Two Bit da Vinci yes, I was looking at the comments to see if anyone else had cathed it, the video is great, just a small error. Thanks for the awesome content.
A couple of things I noticed that you missed. Whilst Panasonic own and operate the cell manufacturing side at Giga Factory 1, Tesla have been instrumental in developing the various cell chemistry's and form factor. Also, the latest info from the last share holders meeting, it was mentioned that the next generation cell would be cobalt free.
Steve Gigafactory is Tesla own and run (it’s Tesla’s name on the side). It’s that Panasonic has significant invented in it and provided the manufacture expertise and machines. They are the cook to Tesla’s recipe
[Ricky] so manufacturing process, optimizations in size per density and price, are where Tesla shines. But in terms of Battery chemistry, Panasonic is king. Great comments, we are so blessed to have such an amazing community of people like you with such good insight. I'll look into the next generation of batteries ,and if they are indeed Cobalt free. thanks again, we hope you'll subscribe, you the kind of person we need in our journey.
"Tesla have been instrumental in developing the various cell chemistry's and form factor." They use a standard form factor.......... and the chemistry too isn't all that special. Other manufacturers just have oped for cheaper alternatives with slightly worse performance characteristics but also a lower environmental impact and with a reduction in the reliance on controversial materials. And Cobalt is instrumental in the lifetime characteristics of LiIon batteries. Change that and you are back to bog standard 18650.
Another very important reason for using several large cylindrical cells is cooling performance. The cooling loop is wound through the batteries and the cell size is optimized for an ideal surface area-to-volume as determined by the necessary worst-case cooling performance. It also reduces the risk of a cascading fire since the energy in each cell is smaller, and it increases the system-level tolerance for cell failure since a failed cell will either fail to conduct or short and cause the fuse to open, and in either case this will have next-to-no noticeable effect on the battery overall since each battery pack features several thousand cells.
Sounds good, this is the design aspect that Nissan keeps absolutely flubbing over and over again, to me their ignorance of the importance cooling performance is astounding, doubly so since they also owned their own battery production until very recently, and ALL of the automotive companies have way more experience with liquid cooling systems than Tesla does.
I am a 20 year engineering professional. I discovered your channel yesterday an have been watching your videos for the past couple days. I must say you are amazing at explaining very technical engineering subjects. Keep up the good work.
The electric vehicle batteries are charged in the garage at room temp (+ 20 Deg C.) How much energy is lost from the battery at minus 20 Deg. C or at lower temperatures ? Regards, Patricia,
Awesome content. Well structured and understandably presented. There are some setbacks like the weight swap and some forgotten letters here and there, but this can be fixed with some reviewing. I see great potential in this channel. Keep it up.
To my understanding the configuration of cylindrical shape of battery is safer as well. Each sheets of metals are rolled up together to form the cylinder. During rough drive the vibration force exerted on each sheet is tangent to the cylinder. For comparison, non-cylindrical battery, during vibration the force is perpendicular to each layer.
Shane Campbell There you go! Sweeping statement, untrue.... Gives wrong information to those who aren't inclined to check, but may pass the info on....... Easy!
Roger Starkey and yet you have no information to disapprove. IIntetesring! Ever hear of an i3, leaf burning an owner alive or firedept unable to extinguish... the dense packing by Tesla has consequences, like it or not!
Shane I see that your distrust is no longer related to battery's shape. Perhaps you will find comfort to know NFPA report everyday there is one person died from car fire. On average there are 31 car fires per hour. -www.nfpa.org

What is the range with the electric heater and defrost fans on in a cold Canadian winter? That 300 miles will go to 200 miles which is not even a road trip in Canada. Batteries hate the cold. My E-Bike has a $900 LiFePO4 and speed and range drops below freezing.
I should start this post with the note that Norway is one of Tesla's best markets. In fact, the Model S is one of the best-selling cars in Norway (#4 across all categories in 2017. The best selling car was the VW Golf, most of which were the hybrid version). Source: cleantechnica.com/2018/02/17/will-new-nissan-leaf-best-selling-car-norway-year/. If you think Canada gets cold, Norwegians will give Canada a run for its money. Batteries aren't as good in the cold, but big battery packs will heat up quiet a bit when discharging - especially if the sensors and computers specifically tell them to charge/discharge in a way that produces more heat. Also, electric motors are far less sensitive to cold start issues than internal combustion motors, so a complete non-start is no longer possible. To me personally, this factor alone is enough to justify that an electric car is more reliable than internal combustion in cold weather. There are few things less comfortable than jump starting your car on a freezing cold morning. For comfort in the cabin, I'm not sure about the Model 3 but the Nissan Leaf uses a (reversible) heat pump, and that handles both heating and cooling. That's about 4 times as efficient as electric-resistance heating. The Model S uses the electric resistance heating. Union of Concerned Scientists have an article showing 2-5 kw power usage for the Leaf, at blog.ucsusa.org/dave-reichmuth/electric-cars-cold-weather-temperatures. That includes all the cabin electronics, not just heating and cooling. Someone has tested this with the Model S (www.teslarati.com/energy-saving-tips-tesla-subzero-weather-using-seat-heaters/) and found that setting the heater as high as it will go can consume 18 miles of range per hour - but with the caveat that this increases the temperature to a ridiculous 108 degrees Fahrenheit(!!!), so you'll probably turn the heater down within a few minutes unless you really want a sauna experience. Overall, to keep the cabin temperature at the standard comfortable temperature of 74 Fahrenheit, you'll lose 1 mile of range per hour. You'll lose more range than that simply due to the higher air density that you have to drive through.
@@TheFragturedNerd Give it another 10 years or so for their production to really ramp up and for more model options, people like you are the market they're trying to reach. They had to do all of the expensive and sporty stuff to prove to investors and customers that EV's aren't lacking in capability. That said, I'm in the same boat, I can't wait to have the money for a Tesla.
Good job! Clear and well put together! Only one detail: there are about 2.2 lbs per kg. So the price of the raw materials for kg needs to be rectified.
Another big plus for small cells in Tesla is that each small cell can be quickly cooled of or warmed up, quickly, if necessary. Lithium batteries hate being too cold or too hot. In the Tesla packs, each small cell is partially wrapped by a liquid cooling 'blanket' that can provide cooling , in the fast charging mode, or heating, in the artic like conditions. The cabin A/C provides colding. For hoting, all on board hoting areas are used(ie...computing heat and whatever other heat sources can scrounged up) . If that isn't enough, resistance heaters are used from the battery, and this is a significant battery drain which leads to big losses in m.p.g. The colding losses are smaller.
@@TwoBitDaVinci I meant what about cobalt's specs like you've explained with Silicon Oxide and Graphite? Does reducing the amount of cobalt decrease energy capacity or anything like that?
[Ricky] Dude we're HUGE FANS!!!!! We love your channel and I've probably seen every DIY powerwall video you've made :) any chance you're interested in a future collaboration?
Teslas video's are soothing . Because I've deans listed for years at LA trade tech in electrical math, refrigeration and engineering . I can't be lied to about anything . Look forward to part 2.
Great video, sub’d for sure. One important thing you didn’t mention about Tesla’s small cylindrical cells vs the larger flat cells used at the competitors, is that the cylindrical cells have a much greater lifespan due to it’s physical shape, it simply can’t expand and contract as much as a flat cell.
Yes, especially in the Model 3 where they have aluminum cooling radiators that surround each individual cell, this is why it doesn't overheat like other EV''s and can be tracked: markets.businessinsider.com/news/stocks/tesla-stock-price-has-remarkable-battery-tech-that-has-been-largely-overlooked-2018-6-1027327792
10:20 well you can do the exact same thing with pouch and prismatic cells. if you want twice the range, you're gonna need twice the batteries, doesn't matter if it's 5000 small or 20 large ones.
the bigger the battery, the less flexibility you have right. A car chassis has reinforcement points, ridges grooves. So the smaller the battery, ideally the more flexibility you have in designing packs. I understand your sentiment though.
Yeah not directly it’ll require a whole new module and cooling. But I’d imagine when battery production continues to scale up, they’ll come up with a replacement pack for those cars.
I am actually thinking about getting a TMX, but trying to decide between the 75D and 100D. I just don't know if ~$16k is worth the extra cost and I am concerned about the problem seen with the 90D battery pack advanced degradation compared to the good degradation performance of the 85D. Do you know if the advanced degradation seen on some of the 90Ds would also hold true with the 75D or 100D battery packs?
You forgot one very important part of why tesla uses small cells instead of bigger cells. This is because of reparability and refurbishing. In large batteries that are solely produce to fit a specific design, the interior design of the battery makes it hard to isolate problematic portions of the cell. But with smaller cells like what Tesla uses, its much easier to find the problematic cells, remove them from the battery pack and have them recycled. This leads to a much smaller percentage of the battery pack needing to be replaced upon imminent failure.
Reparability = bullshit. It's just a design they embraced from day 1 because they had to use off-the-shelf computer parts to fill their Lotus Elise. Now they're optimizing, but, still, there's need to cut costs, so they will keep almost the same kind of harnesses and just make their custom cells, cells that they probably custom-ordered from a laptop parts maker in china.
Also, the cell used are already common format, the 18650 format is the most prevalent one in vaping devices as it can deliver a lot of power in a burst fashion. ( my lg hg2 are rated 20A continuous and 35A burst discharge rates ). But only 3A/h of capacity...
@@MmeHyraelle They dont use 18650 anymore, not since they started production on the Tesla Model 3. Now they use their own modified version of the 18650, its taller and wider but double capacity to a max of 6000mAh and uses more reliable materials.
Nice video! I think you will find that the Tesla's with different batteries in fact run at different voltages. 60 vs. 85 for instance. I see people supercharging those on youtube and they have different voltage ranges...
My Camry Hybrid has NiMH cells. Any tips on swapping these out for lithium packs? Mine's a 2016, and on the 2018 they added another 1.0 kw lithium battery along to the 1.6kw NiMH battery - which they also do to the Prius Plug-in. So it should be easy, at least in theory, right?
[Ricky] Yeah the issue you'll run into is in the difference in core voltage per cell due to different chemistry. I think NiMH cells have a voltage closer to 1.2V so it'll take a little problem solving, but I'm sure you can! Let me look around online, and see if there is any resources on this! I also recommend Jehu Garcia's youtube channel, he does awesome stuff like this all the time :) Cheers Stephen!

Thanks, in the early 70's I worked driving a propane poll hyster, hauling rolls of carpet. The company had a new ideal of doing things. They brought in this much smaller, total electric poll hyster. All of hyster drivers thought, "no way, this little thing can handle the work load, can't possible do the job". Well needless to say, after a week or so of using this smaller total electric hyster, well all fell in love with it. Much fast and, no fumes,, and could pick up more rolls because it was smaller. Faster on everything and only once a day did we have to change out this huge battery. A batter about the size of 4'x4' huge battery. Done with a crane at a place where it was done quickly 15 minutes tops. The whole plant eventually changed to "all electric". The little things were so fast we had to have a class on how to drive them slower and safer. Carrying possibly 3 to 4 tons of carpet can be dangerous. So electric is where the country needs to be. I'm guessing I will love Tesla but they are pricey. I'm not sure which one to buy. 310 mile range on the newer S models or a P 90 much faster but older one. I found one for 62 thousand a used one but a new Model S is about the same. So new or old? I truly don't know. Thanks for your video.
@@chevychase3103 We're sticking our neck out to buy one and we might not. It's hard to tell what the good Lord wants us to do, after all it's his money the wife says. The price will come down and gas motors are not going anywhere for the moment. I'm sorry you can't afford one. Peace Brother!
Kg-pound conversion is bad. 1 kg = 2.2 pounds, so cobalt is about 90$/kg, nickel is about 10$/kg and so. As a kg is bigger than a pound, 1 kg of something cost more than 1 pound of that. Put correct quickly
Thank you very much for the info. I didn't know what used EV to buy because of the concern about battery life, but now it looks like Tesla batteries are the best, so I'll have to go with that.
On the question of why thousands of cells rather than fewer, larger packs, I believe there are several factors you didn't mention. 1) spreading the charge/discharge current over more cells allows Tesla to charge and discharge faster without overheating. 2) it is harder to cool larger cells than small ones (the internal heat source is further from the external cooling system) 3) degraded/dead cells represent much more of a range loss with fewer, larger cells Also, I don't believe panasonic would agree that the relationship is symbiotic or beneficial. they're apparently pretty pissed at how little they make out of the deal
Lol... You start the video with the question of whether making the batteries is worse for the environment or not. You spent the first 9 minutes apparently building up to an answer... then tell us you don't plan to answer that question in this particular video. Wtf?
@10:00 regarding round vs flat/prismatic. AFAIK there is a much more important reason - the lifetime of the battery. With a cylindrical cell it is easy to maintain pressure on the layers in the battery to keep them from coming apart as only tension in the circumference is needed. With flat/rectangular cells this is much more difficult and would need an extremely heavy metal case to provide the same pressure against delamination. We've all seen smartphones with a bulging back, or even a broken screen due to the battery expanding. Now while the exp[ansion is itself a product of battery deterioration once the layers loose contact the process accelerates and the battery deteriorates even more quickly. On the other hand a cylindrical case will maintain its dimension regardless and keep the layers in contact, any pressure in excess of what the cylinder can take being released at the ends.
@@brett7011 Nitpick!? No, that is not nitpicking! If that is a nitpick then we would not been in space, or even have planes! Sorry that a pretty important thing is a nitpick for you. ,,Explain" what? Every other comment is about it but whatever...

Curious and sorta unrelated question. As I'm close to retiring and researching 55+ communities I was curious if Tesla would consider building a Tesla golf cart? I know the Yamaha gas cart is the only long distance cart with a 3 gallon gas tank. The battery carts cannot compete with range as of now. The gas carts are somewhat loud although they've made strides to lower noise level to around 64 decibels. I think it would be a huge market, as retirees would love a quiet, long range golf cart. I hope you can whisper into Elton's ear. thanks for your response.
I think Panasonic won't be a player with Tesla. I would think that Tesla will produce Maxwell dry batteries and super Capacitors in house. Only way they could get the cost down enough to make money on a $35000 car
Cylindrical makes for easy manufacturing. Just roll up the layers and form batteries. This is why AA AAA D C batteries are all cylindrical. As far as size. The thicker they get the more Area is further away from the coolant loop contact. This will result in more uneven cooling heating. Hope that helps
it's waste of materials, time and energy, if you can make battery 3 times faster and cheaper with regular manufacturing. 1852 (or this new on, slightly bigger) format was not invented for use like this. and this is place where tesla fails, it is just too expensive, and without some heavy sponsorship from state etc, musk would be just another business man, talking about science.. and talking buisness: better not to talk about it, when comes to tesla inc., their loss jusr keep growing year by year.
Would just like to complement you on this production. Very well laid out and delivered. Top notch. I found it very informative and even let the adds play in hopes you get paid for your efforts. It did throw me off a sec with mostly American dialect then pronouncing aluminum as a Brit😉 Subscribed👍
Hi. Great video, but I do not understand your math in 5:25 time. If Lithium price is around $7.50/lb, how can be $3.41/kg? As far as I know, pound (lb) is 0.45kg, which mean, the price for kg should be a bit more than double of price per pound. Not vice versa. (Same with Nickel, Cobalt, Manganese, Aluminium... ) Isn't? Update: Sorry, I did not seen your note under video about this at first moment. OK. Fair enough.
I can't get over the fact that in all my years, it has been very uncommon to have *any* battery outlast the device that it goes into. Drills, computers, phones, emergency exit lamps, etc. Then factor in the self-discharge rate. Use it or not, the car is going to be dead in 10 years. I hope I am wrong, but just because a Panasonic 18650 cell is dumped into a car, it is supposed to last longer? Battery technology has a ways to go yet.
Paul I am sorry, but to put it politely, you have literally zero idea of what you’re talking about. You simply can’t compare a drill, laptop, phone etc with a car. The battery management is like comparing cheese with chalk. I have friend in San Diego with a 2012 Tesla, still going fine, still on it’s original battery, LOTS of miles on the odometer.
We will see. Like I said, hopefully I am wrong. It would not take much to implement battery management into a laptop computer, nor a battery drill these days but nobody does that. If you go to flea markets / swap meets, they are littered with battery tools. But they almost never work. If management is the cure to the problem, I wish they would implement it. How many miles is "A LOT?" To some people, that is 70,000. I have 20 years and 248,xxx on my Jeep. It is like one of those car ads where they advertise "Low miles" or "high miles". The odometer only tells about 1/3 of the story anyway. This guy probably has his own home where he can charge the thing daily, combined with the temperate climate of San Diego. It probably lives a good life. As with any car that lives a good life, it'll be a long life. And miles miles miles. It is only 6 years old... maybe 7. Give it another 4 years, and lets see where it is at.
I think there are even better batteries than lithium ion! Also I need a 4x4 pickup truck not a car. I'm totally for 100% quiet vehicles that are cheap, minimal pollution and extremely simple, uncomplicated, very low maintenance and available from other companies than just Tesla. Keep up the good research and work! Have fuN, enjoy
[Ricky] Dodge Chrysler Jeep is one of the most unreliable and poorly made cars out there... I'd rather Have Tesla... but Comparing Tesla to the likes of Honda or Toyota... yeah It'll be a while for them to catch up
i agree. tesla is still a new company. in less then 10 years they will be up there. the only thing right now that makes me not want to support tesla as a company is the lack of consumer available parts. they are very bad about that. i do hope that is to change in the future but i have my doubts
Even if Tesla invents a battery that produces 1000wh/l it will never happen! IBM is your next battery guru! Lithium will be a disaster financially when this comes out!
great video, very informative. I get why they use hundreds of smaller cells, but why cylindrical? why not rectangular? that way there is little or no wasted space between the indivudual cells.. Does the cylindrical shape have any advantage?
The cylinder cell is very easy to manufacture. You can roll the layers up, cut it off, put it in a casing and continue on. Its very advantageous from a manufacturing standpoint. Same reason all batteries are cylindrical basically :)
It’s very advantageous for lots of reasons, including manufacturing, heating, cooling, power density, internal resistance and lots more. Tesla did the Model 3 as a clean slate. Why do you think they stuck with cylindrical cells? It bears little or no resemblance to the S &X, but still uses cylindrical cells, though a larger size 2170 cell. No doubt the S and X will change to them some time in the future.

Awesome content. Well structured and understandably presented. There are some setbacks like the weight swap and some forgotten letters here and there, but this can be fixed with some reviewing. I see great potential in this channel. Keep it up.
To my understanding the configuration of cylindrical shape of battery is safer as well.
Each sheets of metals are rolled up together to form the cylinder. During rough drive the vibration force exerted on each sheet is tangent to the cylinder.
For comparison, non-cylindrical battery, during vibration the force is perpendicular to each layer.
kiryu nil and yet stories of Tesla burning drivers alive occurred every few months.. Safe is relative I guess

There you go! Sweeping statement, untrue.... Gives wrong information to those who aren't inclined to check, but may pass the info on....... Easy!
Roger Starkey and yet you have no information to disapprove. IIntetesring! Ever hear of an i3, leaf burning an owner alive or firedept unable to extinguish... the dense packing by Tesla has consequences, like it or not!
Shane I see that your distrust is no longer related to battery's shape. Perhaps you will find comfort to know NFPA report everyday there is one person died from car fire. On average there are 31 car fires per hour. -www.nfpa.org
Shane Campbell specify which owner was "burnt alive" and which car the fire department was unable to extinguish.

What is the range with the electric heater and defrost fans on in a cold Canadian winter? That 300 miles will go to 200 miles which is not even a road trip in Canada.
Batteries hate the cold. My E-Bike has a $900 LiFePO4 and speed and range drops below freezing.
I should start this post with the note that Norway is one of Tesla's best markets. In fact, the Model S is one of the best-selling cars in Norway (#4 across all categories in 2017. The best selling car was the VW Golf, most of which were the hybrid version). Source: cleantechnica.com/2018/02/17/will-new-nissan-leaf-best-selling-car-norway-year/. If you think Canada gets cold, Norwegians will give Canada a run for its money.
Batteries aren't as good in the cold, but big battery packs will heat up quiet a bit when discharging - especially if the sensors and computers specifically tell them to charge/discharge in a way that produces more heat. Also, electric motors are far less sensitive to cold start issues than internal combustion motors, so a complete non-start is no longer possible. To me personally, this factor alone is enough to justify that an electric car is more reliable than internal combustion in cold weather. There are few things less comfortable than jump starting your car on a freezing cold morning.
For comfort in the cabin, I'm not sure about the Model 3 but the Nissan Leaf uses a (reversible) heat pump, and that handles both heating and cooling. That's about 4 times as efficient as electric-resistance heating. The Model S uses the electric resistance heating. Union of Concerned Scientists have an article showing 2-5 kw power usage for the Leaf, at blog.ucsusa.org/dave-reichmuth/electric-cars-cold-weather-temperatures. That includes all the cabin electronics, not just heating and cooling. Someone has tested this with the Model S (www.teslarati.com/energy-saving-tips-tesla-subzero-weather-using-seat-heaters/) and found that setting the heater as high as it will go can consume 18 miles of range per hour - but with the caveat that this increases the temperature to a ridiculous 108 degrees Fahrenheit(!!!), so you'll probably turn the heater down within a few minutes unless you really want a sauna experience. Overall, to keep the cabin temperature at the standard comfortable temperature of 74 Fahrenheit, you'll lose 1 mile of range per hour. You'll lose more range than that simply due to the higher air density that you have to drive through.
As a huge fan of both Tesla & Panasonic, I'm rooting for them big time. Love my Model 3!

you're so lucky :/ i'm a huge fan of tesla but will probs never have the money for 1 :/

Good job! Clear and well put together! Only one detail: there are about 2.2 lbs per kg. So the price of the raw materials for kg needs to be rectified.
Yes we noted it in the description and address it in part 2
Another big plus for small cells in Tesla is that each small cell can be quickly cooled of or warmed up, quickly, if necessary. Lithium batteries hate being too cold or too hot. In the Tesla packs, each small cell is partially wrapped by a liquid cooling 'blanket' that can provide cooling , in the fast charging mode, or heating, in the artic like conditions. The cabin A/C provides colding. For hoting, all on board hoting areas are used(ie...computing heat and whatever other heat sources can scrounged up) . If that isn't enough, resistance heaters are used from the battery, and this is a significant battery drain which leads to big losses in m.p.g. The colding losses are smaller.
You’re talking part 2 ;) yes great points!

Two Bit da Vinci But what is Cobalt's influence on battery performance if Tesla's putting less with each generation?
Yes down to less than 3% now

is aluminum in Tesla battery the outer shell of battery cell or particles inside chemically mixed with Lithium & Cobalt?
Both. There is aluminium in the cathode, and the outer casing is also aluminium for heat transfer purposes mostly.
Excellent video, apart from the small detail of prices being wrong when comparing pounds and kilograms.
Yes we noted the issue in the video description and also in part 2. Cheers
Great video, sub’d for sure. One important thing you didn’t mention about Tesla’s small cylindrical cells vs the larger flat cells used at the competitors, is that the cylindrical cells have a much greater lifespan due to it’s physical shape, it simply can’t expand and contract as much as a flat cell.
[Ricky] Great point, we will cover some of these sorts of benefits in part 2!
Does it also allow for better thermal management?
[Ricky] Absolutely, we'll cover that in P2.
Yes, especially in the Model 3 where they have aluminum cooling radiators that surround each individual cell, this is why it doesn't overheat like other EV''s and can be tracked: markets.businessinsider.com/news/stocks/tesla-stock-price-has-remarkable-battery-tech-that-has-been-largely-overlooked-2018-6-1027327792
What a great video! This content was very informative and professional.
Keep it up!
10:20 well you can do the exact same thing with pouch and prismatic cells.
if you want twice the range, you're gonna need twice the batteries, doesn't matter if it's 5000 small or 20 large ones.
the bigger the battery, the less flexibility you have right. A car chassis has reinforcement points, ridges grooves. So the smaller the battery, ideally the more flexibility you have in designing packs. I understand your sentiment though.
Do you think the 2017 Tesla Model S and X can be fitted with the new batteries of the model 3 when it is time to replace the old model S/X batteries?
Yeah not directly it’ll require a whole new module and cooling. But I’d imagine when battery production continues to scale up, they’ll come up with a replacement pack for those cars.
I am actually thinking about getting a TMX, but trying to decide between the 75D and 100D. I just don't know if ~$16k is worth the extra cost and I am concerned about the problem seen with the 90D battery pack advanced degradation compared to the good degradation performance of the 85D. Do you know if the advanced degradation seen on some of the 90Ds would also hold true with the 75D or 100D battery packs?
You forgot one very important part of why tesla uses small cells instead of bigger cells. This is because of reparability and refurbishing. In large batteries that are solely produce to fit a specific design, the interior design of the battery makes it hard to isolate problematic portions of the cell. But with smaller cells like what Tesla uses, its much easier to find the problematic cells, remove them from the battery pack and have them recycled. This leads to a much smaller percentage of the battery pack needing to be replaced upon imminent failure.
[Ricky] Didn't forget, that's in Part 2, where we talk about the battery pack!
also thermal control is much simpler and safer, that was also one of the major reasons behind going for small batteries
Reparability = bullshit. It's just a design they embraced from day 1 because they had to use off-the-shelf computer parts to fill their Lotus Elise. Now they're optimizing, but, still, there's need to cut costs, so they will keep almost the same kind of harnesses and just make their custom cells, cells that they probably custom-ordered from a laptop parts maker in china.
Also, the cell used are already common format, the 18650 format is the most prevalent one in vaping devices as it can deliver a lot of power in a burst fashion. ( my lg hg2 are rated 20A continuous and 35A burst discharge rates ). But only 3A/h of capacity...
@@MmeHyraelle They dont use 18650 anymore, not since they started production on the Tesla Model 3. Now they use their own modified version of the 18650, its taller and wider but double capacity to a max of 6000mAh and uses more reliable materials.
Nice video! I think you will find that the Tesla's with different batteries in fact run at different voltages. 60 vs. 85 for instance. I see people supercharging those on youtube and they have different voltage ranges...

My Camry Hybrid has NiMH cells. Any tips on swapping these out for lithium packs? Mine's a 2016, and on the 2018 they added another 1.0 kw lithium battery along to the 1.6kw NiMH battery - which they also do to the Prius Plug-in. So it should be easy, at least in theory, right?
[Ricky] Yeah the issue you'll run into is in the difference in core voltage per cell due to different chemistry. I think NiMH cells have a voltage closer to 1.2V so it'll take a little problem solving, but I'm sure you can! Let me look around online, and see if there is any resources on this! I also recommend Jehu Garcia's youtube channel, he does awesome stuff like this all the time :) Cheers Stephen!

Convince me with facts, not with BS.
how is the price per LB higher for you, when compared to KG? You get more stuff in a KG than in a pound.
Great work. Keep the good coming and all these people being negative shows they don't have the capability to make an informed video like this.
good job explaining the cells strategy. Interesting times - with Tesla model 3 ramping, we'll see it all prove out well or flop on it's own weight... I'm wishing them well !
[Ricky] Thanks, yeah its the most critical period in their history and its great knowing they've put so much thought into everything.
Lyle Stavast well you you just got your wish Tesla has even out sold some of the more popular gasoline cars in the Tesla three and they haven’t even caught up to all the customers who are buying them now imagine when they catch up to the people who want them and that day is closing fast.
Ummm... not sure why it was really all that critical to specifically state it - isn't it generally understood that that is why it's called what it is ?
October and November numbers are really critical, as are the 3Q18 financial results due out maybe the 1st week of November. You can see all the plugin player vehicles (pure EV and plug-in hybrids) in the space at this site - which shows Tesla just completely dominating the space now... insideevs.com/monthly-plug-in-sales-scorecard/
actually they are going to announce 3Q financials on Wed, 24 October... that was announced on Monday night 2 days before... bode well, or ill ?
Thanks, in the early 70's I worked driving a propane poll hyster, hauling rolls of carpet. The company had a new ideal of doing things. They brought in this much smaller, total electric poll hyster. All of hyster drivers thought, "no way, this little thing can handle the work load, can't possible do the job". Well needless to say, after a week or so of using this smaller total electric hyster, well all fell in love with it. Much fast and, no fumes,, and could pick up more rolls because it was smaller. Faster on everything and only once a day did we have to change out this huge battery. A batter about the size of 4'x4' huge battery. Done with a crane at a place where it was done quickly 15 minutes tops. The whole plant eventually changed to "all electric". The little things were so fast we had to have a class on how to drive them slower and safer. Carrying possibly 3 to 4 tons of carpet can be dangerous. So electric is where the country needs to be. I'm guessing I will love Tesla but they are pricey. I'm not sure which one to buy. 310 mile range on the newer S models or a P 90 much faster but older one. I found one for 62 thousand a used one but a new Model S is about the same. So new or old? I truly don't know. Thanks for your video.

Kg-pound conversion is bad. 1 kg = 2.2 pounds, so cobalt is about 90$/kg, nickel is about 10$/kg and so.
As a kg is bigger than a pound, 1 kg of something cost more than 1 pound of that.
Put correct quickly

Working on it now!
On the question of why thousands of cells rather than fewer, larger packs, I believe there are several factors you didn't mention.
1) spreading the charge/discharge current over more cells allows Tesla to charge and discharge faster without overheating.
2) it is harder to cool larger cells than small ones (the internal heat source is further from the external cooling system)
3) degraded/dead cells represent much more of a range loss with fewer, larger cells
Also, I don't believe panasonic would agree that the relationship is symbiotic or beneficial. they're apparently pretty pissed at how little they make out of the deal
So how much do they cost to replace and how often do they need replacing?
the mine you show is a copper mine... and fun fact it's my place of employment.
Lol... You start the video with the question of whether making the batteries is worse for the environment or not. You spent the first 9 minutes apparently building up to an answer... then tell us you don't plan to answer that question in this particular video. Wtf?
Great video! Amazing job keep it up!
@10:00 regarding round vs flat/prismatic. AFAIK there is a much more important reason - the lifetime of the battery. With a cylindrical cell it is easy to maintain pressure on the layers in the battery to keep them from coming apart as only tension in the circumference is needed. With flat/rectangular cells this is much more difficult and would need an extremely heavy metal case to provide the same pressure against delamination. We've all seen smartphones with a bulging back, or even a broken screen due to the battery expanding. Now while the exp[ansion is itself a product of battery deterioration once the layers loose contact the process accelerates and the battery deteriorates even more quickly. On the other hand a cylindrical case will maintain its dimension regardless and keep the layers in contact, any pressure in excess of what the cylinder can take being released at the ends.
If I recall correctly, Tesla's Roadster did _not_ use NCA cells. They are in all of their subsequent vehicles though.

@@TwoBitDaVinci Hi, can I ask what is the price in the chart? They are not the price for pounds, but I don't know what they are.
Curious and sorta unrelated question. As I'm close to retiring and researching 55+ communities I was curious if Tesla would consider building a Tesla golf cart? I know the Yamaha gas cart is the only long distance cart with a 3 gallon gas tank. The battery carts cannot compete with range as of now. The gas carts are somewhat loud although they've made strides to lower noise level to around 64 decibels. I think it would be a huge market, as retirees would love a quiet, long range golf cart. I hope you can whisper into Elton's ear. thanks for your response.
I have a tesla model 3, it has a 300 mile range, but doesn't recommend you charge to full capacity to keep some set of cells as 'spares'
We discuss this in part two. All cells are charged equally so it’s been to just charge all cells to 80-90% whenever possible

Question. How will the threesome between Maxwell Technologies, Panasonic, and Tesla interact?
I think Panasonic won't be a player with Tesla. I would think that Tesla will produce Maxwell dry batteries and super Capacitors in house. Only way they could get the cost down enough to make money on a $35000 car
Pounds and Kilos.... multiply not divide!

Reading all these comments, I'm not even going to watch the video. Y'all should just redo it with the correct math and reupload.
How much of this battery chemistry is recyclable effectively in a cost efficient manner?
Ok on more flexibility by using small cells. Why not use Bigger cells though? Even a 3 or 4 in cube is pretty modular
Cylindrical makes for easy manufacturing. Just roll up the layers and form batteries. This is why AA AAA D C batteries are all cylindrical. As far as size. The thicker they get the more Area is further away from the coolant loop contact. This will result in more uneven cooling heating. Hope that helps
nice video man i like it, you need more subs
thank you sir!
The advantage of small cylindrical cells over prismatic cells is superior heat dissipation.
Indeed
it's waste of materials, time and energy, if you can make battery 3 times faster and cheaper with regular manufacturing. 1852 (or this new on, slightly bigger) format was not invented for use like this. and this is place where tesla fails, it is just too expensive, and without some heavy sponsorship from state etc, musk would be just another business man, talking about science.. and talking buisness: better not to talk about it, when comes to tesla inc., their loss jusr keep growing year by year.

I can't get over the fact that in all my years, it has been very uncommon to have *any* battery outlast the device that it goes into. Drills, computers, phones, emergency exit lamps, etc. Then factor in the self-discharge rate. Use it or not, the car is going to be dead in 10 years. I hope I am wrong, but just because a Panasonic 18650 cell is dumped into a car, it is supposed to last longer?
Battery technology has a ways to go yet.
Paul I’m working on part two as we speak! Please subscribe and wait for part two on Saturday! I’d love your feedback after seeming it
Paul I am sorry, but to put it politely, you have literally zero idea of what you’re talking about. You simply can’t compare a drill, laptop, phone etc with a car. The battery management is like comparing cheese with chalk. I have friend in San Diego with a 2012 Tesla, still going fine, still on it’s original battery, LOTS of miles on the odometer.
We will see. Like I said, hopefully I am wrong. It would not take much to implement battery management into a laptop computer, nor a battery drill these days but nobody does that. If you go to flea markets / swap meets, they are littered with battery tools. But they almost never work. If management is the cure to the problem, I wish they would implement it.
How many miles is "A LOT?" To some people, that is 70,000. I have 20 years and 248,xxx on my Jeep. It is like one of those car ads where they advertise "Low miles" or "high miles". The odometer only tells about 1/3 of the story anyway. This guy probably has his own home where he can charge the thing daily, combined with the temperate climate of San Diego. It probably lives a good life. As with any car that lives a good life, it'll be a long life.
And miles miles miles. It is only 6 years old... maybe 7. Give it another 4 years, and lets see where it is at.

The cylinder cell is very easy to manufacture. You can roll the layers up, cut it off, put it in a casing and continue on. Its very advantageous from a manufacturing standpoint. Same reason all batteries are cylindrical basically :)
It’s very advantageous for lots of reasons, including manufacturing, heating, cooling, power density, internal resistance and lots more.
Tesla did the Model 3 as a clean slate. Why do you think they stuck with cylindrical cells? It bears little or no resemblance to the S &X, but still uses cylindrical cells, though a larger size 2170 cell.
No doubt the S and X will change to them some time in the future.
Wait! What about cars produced from 2013 through 2015? What kind of batteries do they have?
