- What do we do with EV batteries when they need repair? How do we rebuild them? Can a single module be changed? What are mechanics going to have to do in the future with hybrids and EVs?

Great video. Something to note about when you replace modules is that certain chemistries (LiFePO4 comes to mind) has very flat charge curve, so 0,1V difference can be a large difference in charge state. For these chemistries, you should top balance them.
You do this because if you can find a point on the curve where the voltage climbs rapidly with increasing charge, you can be sure all the cells are within a tight range.
This is a lot of effort with high voltage packs, especially if you've disconnected all the bus bars, stopping you from being able to charge large sections at once.
@@ThisRandomUsername yes this is all true! Lifepo4 will definitely have a different charge curve.
10 years ago I built my own electric moped. I built it with 96V large lithium cells (8” tall each). Had to replace every sub module in the moped with 100v compatible ones so I had working brake lights, headlight, signals, etc. I rewound the electric motor with much heavier gauge wire, and much heavier leads to the controller. Put in a very powerful controller I bought from china, and had a custom BMS built in China at a factory to handle the huge amount of current I needed. It was a big job building it all and no info online about any of it as it was very leading edge 10 years ago. Wow it was amazing though. It would do 80km/h, and had over 100km of range. It was stupid quick too. Rode it daily to work for 2 years before I sold it to a friend.
Thanks for the video as it brought back a lot of memories! Hindsight I should prob. have taken more safety precautions with the 96V battery I built from scratch. Bare hands and lots of soldering, with no safety gear whatsoever. 😂 Glad I never made a mistake!
Wow! That is incredible! In modern cars, there is still a 12v circuit for all the other circuits including the BMS. They use a DC to DC converter to bring it from 400v to 12v. I'm having the same problem with any ideas I have to use these modules for any projects as they are 29.6v nominal. I would need a special BMS ordered from a company just to use them for something like that.
Thank you for sharing your project with us! It sounds incredible!
You did an amazing job of teaching during this video btw. I was thoroughly impressed. Good luck with them and if I have any ideas for ya I’ll let you know.
We run 6s1p LiPo packs in series in some of our mid sized 70” RC electric planes which are close to that voltage, but those used cells unfortunately are too heavy and less power dense compared to LiPo cells, or I’d say throw them in an rc plane and fly! Maybe in an RC boat or car would be fun though. 👍
@halflife82 Thank you! I still have more to learn as always. I'll share any new info as the courses roll out. In my industry, the material is still being written for the courses at this stage.
I'm hoping to make an E-bike once I figure out a BMS and controller. Maybe series at 59.2v might work.
I'll keep an eye out for your comments in the future. Keep us posted!
Thank you for that breakdown. I really appreciate it!!
We look forward to diving deeper into EVs in the future!
you are methodical and calm, valueable character attributes (not only) for this profession
We were discussing this last week at work. In this trade, you have to have methods to catch your own mistakes. If you get distracted, it is important to go over all the steps again as people's lives are in your hands when you work on their cars.
One of the best content on the topic. Thanks!
Thanks for the comments!
Sir you give us the very good knowledge thanks a lots
Thanks for your comment! I appreciate it.
Nice detail, u are first person I seen using safety gloves 😂😂😂. I’m doing 2013 model s module replacement and decided to go get some hi voltage glove’s despite no one else using them. Never could find detail video on safety but I will also take out pyro to lower voltage. Thanks for info. , would like to do one of these one day!
Happy to hear! Good luck with your project. When you bleed the cooling system, use a vacuum bleeder. It'll save you headaches. Thanks for the comment!
Nice Job, Well done
Thank you!
Thanks for u contribution
I appreciate this. Thanks!
Beautiful video 😎😎😎
Thanks! I just subscribed to your channel as well. Great info! 👍
Excellent video. Keep doing similar educational videos. Your subscribtion count will grow in no time.
So far that has been true! Our brake service video was the most popular. Did you see the short we did about the hybrid Ioniq? Thanks for the comments!
Very nice video. I would suggest some eye protection in the future ones.
Excellent point! Thank you!
But, but, shhhh, don't tell people that a battery can be repaired so cheaply. The anti-EV trolls want everyone to believe the entire battery pack (very expensive) must be replaced every time.
Ha ha, yes, we addressed that a little in our Tucson hybrid video here: ruclips.net/video/hNGFzAHPTN8/видео.htmlsi=KlliwtDHGYSLyEVi
Check it out right around the 10:00 mark! Thanks for the comments.
No. That's the auto manufacturer telling you that.
I know nothing about EV but I found this very interesting.👍
I hope to show that EVs are rebuildable. A lot of people think that they are just thrown out. Thanks for the comments!
This industry needs building norms in order to facilitate battery repair since is the most expensive part
It sure does. You'd be surprised how difficult a Tesla battery rebuild is compared to this one...
Impressive, am interested in Ev battery maintenance.
I hope they release the new course about this subject at Hyundai soon. I'm looking forward to providing more info!
Thanks my vehicle is prismatic so look forward to have a go.
Us too. We're going to keep our Kona EV for a long time, so when it does start to fail, we can pull it apart and replace whatever is necessary.
Even Fluke talks about the “one hand rule” in their materials in measuring high voltage. My experience with with electrical equipment tells me that any arc is looking for a ground. If I touch a sources of voltage with bare hands or while wet an arc will discharge the voltage to the nearest ground being the nearest conductor whether of not I have my hand behind my back.
However this DC battery isn't "grounded" as a normal 12v system. To complete the path you would have to contact both + and - at the same time.
I hear that all these trades are taught slightly different rules when it comes to high voltage.
As a twenty six year electrician. Not only do you need protective gloves. At those voltages, you need a 70e rated suit, face shield!
At 270 volts? Keep in mind that this is not Earth grounded. There is definitely danger of explosion if the terminals of the battery touch or arc flashing. Also, there is danger of your heart stopping if the current from the battery were to go through your body.
In this video, we share what we have learned from our own automotive related courses. There is a new battery rebuild course coming out soon, and we will report back any new information we're given.
You need a meter that has a slot to hold one of the probes, then use ground lead with an alligator clip. Then you only need one hand to make high voltage readings.
Good suggestion! Thanks.
Cool video, and good safety advice. Are your tools / bit holder the insulated VDE type? Usually VDE tools are Red and Yellow and generally rated up to 1000V
Ironically, these tools are optional extra protection. They are a great idea and I would recommend them. But in our training programs, they are not required. The proper use of HV gloves and safety shoes are meant to protect the user. The insulated tools available are just an extra step of safety. If you check out some of the shorts I posted about 12v batteries in the Tucson, you'll see why these tools might be a good idea 💡. So, no, the tools seen here are normal shop tools and are uninsulated. Just be careful and make sure the gloves are up to date and checked every time they are used.
@@livewirereview Thanks for the reply, I think I'd use VDE ones just as another layer of safety. I wonder if a VDE bit holder for your driver would protect the tool/battery from being zapped by the car battery.
Everyone seems to be commenting about safety. I guess I can play along.
You should be wearing a full fire retardant suit, like 20 cal, and only natural fiber clothing like cotton underneath. A full face shield with glasses behind. I work in power generation and do switching of 128kv. In reality I would suggest wearing natural fiber clothing with long sleeves and a face shield until you verify dead or safe from fault. As far as the “one handed” rule, Yeah, I wouldn’t worry. You are wearing high voltage gloves, like way above the voltage you are working with. I have never seen a coworker do work or test with just one hand.
Overall, cool presentation.
Thanks for the comments! It seems that our trades come with very different education in this field. I still wonder if a lot of the differences come from the fact that it's DC voltage with no earth ground vs. AC with potential for shock to ground. In our case, the only danger is a short between the 2 main terminals or any 2 terminals above 48v DC.
@@livewirereview could very well be. Our big concern is an arc flash and not so much electrocution.
Is there any potential for that battery to short out and explode? That would be similar to an arc flash.
There is a potential for a short, but there is a disconnect in the middle. Sometimes there are 2 disconnects. The last hybrid I worked on had the plug, a disconnect, and a high voltage fuse.
Hyundai is currently developing a battery rebuild course at their training center. I will pose some of these questions to the instructor when we go there.
@@livewirereview yeah, I would definitely suggest asking experts about PPE rather than taking advice from us keyboard experts.
Getting into the rebuild game early is going to play out very well for you in the not to distant future. These batteries may last a long time, but the market share of EV purchases is growing.
Great content mate, do you have an online training on this
I'm a licensed technician at Hyundai. We received training at head office for this. There is a new set of courses out. I will update at some point.
What certification/training you need in order to service / repair / rebuild these batteries? Any good training recommendation?
So far, the courses are still being created. Out in Nova Scotia, the Steele Auto Group is helping Consulab make demonstration vehicles for our colleges right now.
Check with your local colleges and see who is offering courses. Around here, there are some additional elective courses (but aren't mandatory at this time) at local colleges like George Brown. But this is strictly an online course.
Here, we're patiently waiting for Hyundai to release their official battery rebuild course.
Perhaps there will be a follow-up reassembly video but I have an observation about the busbars. They appear to be fully insulated so the interface with the cells is invisible. Is there provision, indeed a requirement, for a very low resistance bonding test across that interface to be carried out? Because of the current drawn any resistance would generate a great deal of heat.
Also, is an in-load test facility available to test for internal resistance of cells and establish battery performance? Just measuring off-load voltages is a poor means of declaring a battery not just serviceable but also delivering full performance.
Actually, the bus bars are nothing more than small pieces of metal. They come out from the orange casing around them as they are inside the battery case. This used to be a common failure point on older prius' batteries. No, there is no test for this. We either replace them or just visually inspect for corrosion first before installing.
As for the cell performance; specialty shops do have the equipment to test for cells using amperage and voltage sag. However, in this vehicle, all of that is done by the BMS. It's very sophisticated and tests for temp, voltage drop, amperage draw, and even cell expansion. The BMS in this battery determined that 2 cells were dropping voltage slightly faster than the rest under load and set a DTC.
@@livewirereview Thank you, most informative.
One hand rule.. instead you missed to check voltage to case and your leg touched the metal, zap.
Luckily, it won't complete the circuit through the metal case. Being an isolated DC circuit. But yes, the one hand rule is a pain.
i totally saw that one bolt fall in the drain well XD
Meh. It's in my shop now, ready for more experiments 😆.
…in the future. how far away are we from HV battery rebuilding? What companies are out there doing this now? Is it an option for PHEV owners, that are outside of vehicle warranty? How does it compare cost wise to a replacement?
@dk6420-v1w there are companies out there performing these services already but you will have to search for them. We have about 3 in the Toronto area from my searches. Yes they do plug in hybrid batteries too. We only have data for a hybrid one recently. $10,500 over the parts counter at a dealership and $1,200 to rebuild the one that was already in the car.
I'm working on a custom nissan leaf cell battery bank right now and I accidentally shorted one of them against the case. KABANG! 7v dc blew a chunk off the enclosure. So as I near the end of the buss bar connections I am around 360v. Now I am an red seal electrician and have worked around 347/600v ac and seen the aftermath of faults that blew doors off disconnects and one incident that nearly took my coworkers life. Part of the reason I left that trade was the all the close calls and dangerous situations I was put in. I was genuinely nervous and afraid of this battery bank. Not only do you have an extreme arc flash hazard but it's also DC voltage which kills you easier than AC. No way to de-energize the cells. I don't think I would do this for a living for any less than $100/h!
You will notice my hand shake in some of the scenes of this video for that very reason! Thank you for this comment!
As for battery recycling at end of life, it's a little easier for them because they get to de-energize the whole battery into the grid before it is disassembled and shredded.
I have been near a simple 12v lead acid battery when it exploded under the hood of a truck once. It's a very dangerous thing. This is more for educational purposes for those wondering what is involved in a rebuild. The utmost care must be taken when performing this kind of work. I'm looking forward to Hyundai's new course on this that comes out later this year or early next year.
Is the BMS capable of individual cell balancing? Thank you
Yes, and it is able to balance at all charge levels. Unlike cheap BMS systems from electronics, this system doesn’t just bleed excess voltage into heat at 100% charge.
Do y'all replace modules in the Tesla model S batteries?
It can be done. There are lots of little shops popping up all over that do change modules in older model S vehicles. On one of the Facebook groups, there is a forklift shop that does this in their spare time.
What happens if an E vehicle is in an accident and the battery gets damaged and you inadvertently touch the metal of the vehicle? In the Toronto area there are an average of 600 accidents every day.
The HV battery is not grounded to the vehicle. It would take a very unlikely set of events to happen for the vehicle to become electrified as the section touching would only short circuit in that particular area. There is a strong safety cage around larger batteries and spacing and sensors that disconnect power in accidents.
The volkswagen e-golf is also air coooled, similiar to the Leaf
That's true. Our tint installers use E-golfs as their runabout cars. When there are no level 2 charge stations around, they charge them from their F150 Lightning!
Normally wear a harness when working on these, not to save you because its instant death you won't just get a little shock ,its to recover the body as tou will stick to it.
Sorry I missed this comment a couple of weeks ago. A harness would be a good idea! What we have been told to use in our industry is a hook or non conductive rod to push a person away from electric shock. You are correct.
The fly in the ointment is that EV batteries are made not to be serviced or repaired. Sandy Munroe, et al rave about how batteries are part of the vehicle structure and how wonderful it is that the plot is glued together instead of those expensive nuts and bolts. Yep, it is wonderful until you have to try to fix it. Tesla doesn't even bother to service a defective battery. They just sell you a new one for $30,000 dollars instead of replacing the $2 "D" flashlight cell that's gone bad.
Not all batteries are meant to be serviced. Hyundai batteries like this are actually very easy to service.
The Tesla battery may not be serviceable as easily, but it is by far the lowest cost to replace of any EV on the market due to economies of scale and recycled materials from Redwood. It's about $20k to $24k here in Canada with labour at the moment.
A comparable Hyundai battery fully assembled is over $30k just for the part. A Mach-E battery costs more than the vehicle in some cases.
Are the BYD blade batteries easier to access and replace than those glued together Teslas??
@@STOLSPEED we won't know until we open one!
These batteries look like they are a lot easier to work on than a tesla. I'm not sure why they insist on the the high voltage. What I'm saying is the high voltage is needed for acceleration. Why do ev,s have to be race cars? Do they make golf cars that can go 0 to 60 in 6 seconds? Sorry but a more practical ev would have the same acceleration as a 4 cylinder economy car. The cost of the battery is not a problem if it can be fixed for 1,000 dollars. Replacing an ev battery is the same as replacing a motor because the water pump broke. We replace the water pump. So fixing they battery is the future of ev's.
@MegaFlguy to answer your question on HV. High voltage has A LOT of benefits in a vehicle regardless of it's power output. Higher voltage allows for far smaller wiring everywhere in the vehicle. This reduces weight, amperage, cost, and complexity. Going from 400v to 800v even has the benefit of smaller DC fast charging cables with twice the output for the same size wire.
As for economy EVs, they do exist! The Nissan Leaf, Chevrolet Bolt, Hyundai Kona, Hyundai Ioniq (original version) and even base model 3s.
Thanks for the comments! Rebuilding batteries will be a lot cheaper than replacement in the future for sure!
Hey Mate, as a HV sparky on mobile mining gear, Diesel electric drive truck etc , the onearm rule is simply ludicrious and more dangerous, gloves yes, safety glasses yes definietly and no exposed arms like you were, rolled down sleeves without exposed skin to contact.
It was just a huge part of our automotive HV training. I would rather work without the one arm rule but it's been drilled into us from every instructor. Linesman training is different than our training is as well.
@@livewirereview Yep, curriculums in trade schools can be contentious sometimes with health and safety regulations. Purely out of interest is it a limited electrical ticket for your auto sparky up to 3 phase or full registration and licence like mine for all sparky work up to national grid, theres quite a difference here for law of liability.
It's barely a part of our curriculum now. But it was added to the test when I wrote it. The only 3 phase we work with would be a disabled motor to test windings if it came down to it and we can change out capacitors and such if required. At this time we receive training through the dealer groups or you can take a short course at local colleges to add on to your knowledge set but no actual certifications at this time. A lot of places deep diving into this stuff are self taught or are at the engineer and programming level. Like Gruber motors in the USA for example.
Refer units are running 600v 3phase, sometimes necessary to check voltage and for voltage drops across a contractor, always try to do it with one hand, but no gloves, and never in a rainstorm.
1 hand rule is ludicrous. EVS are rediculously dangerous and useless in so many ways.
So the 'overhaul' on the EV battery is somewhat like an automatic transmission where the technician only changes out the individual faulty clutch pack, not all of them at the same time. With the battery they only replace the individual faulty battery module or cell, not all the modules or cells at the same time. That's considered to be an 'overhauled' unit. So you've got one new module or cell and perhaps others that may be 4 years old in the same battery. So the battery could be fine for 12 months or more (no specific time able to be given) after the overhaul, until the old modules or cells begin to fail, then it's back in the shop again for another overhaul.
Close, but it's usually done with matched cells. Replacing only one cell would cause early failure of the pack. The BMS' job is to keep every cell at exactly the same voltage all the time to prevent early failure. So when rebuilding a battery, you either use "matched age and voltage" cells or totally brand new cells with matched voltage.
Specialty rebuilding shops will have lots of cells to choose from that were matched together from other torn down batteries. It takes a lot of inventory to do that.
@@livewirereview Okay so pls tell me approximately how much people are spending to have their battery repaired as a dollar figure and what's the warranty period on the repair?
@jamessmyth5949 figures like that are all over the place right now as it's still early in the game. The average Tesla battery is about $24k canadian with installation from Tesla. A Leaf is usually around $16k.
My neighbour had an issue with their Smart EV but that battery is very small. It was $12k from the dealer but she got it replaced for about $6k I believe. (Canadian figures for all).
@jamessmyth5949 try contacting ingenext in Quebec and see what kind of prices they are charging. I don't think they rebuild batteries just yet but they have several used options available.
This will be the future of car repair. Mechanics will need to shift into electronics techs.
Yes, that's true! Training courses are slowly rolling out in the industry.
Here's the guy that's gonna be a bizzionaire.....follow this cat closely!!...There's only so much the industry can hide
Haha, I just share the information. Hyundai has a course coming out that will teach us how to rebuild their batteries very soon. I'll report back after we attend.
I'm a battery discharge engineer with a battery recycler. I need to get my operators trained to disassemble live packs to the module level. Where can i get this training?
5:35 -> bmw PHEVs have also liquid cooling for their battery pack.
Good to know, thanks for the info!
It would be bad than good in the long run, since engineering changed. Totally make dangerous case.
We will learn and adapt as batteries change over time. This is only one example. A Tesla battery looks very different than this inside.
You REALLY should be wearing Arc Flash PPE to be OSHA compliant.
As stated with others comments, our training specifically calls for CSA safety shoes with the omega symbol, HV gloves and protective gloves overtop. We are then taught the one hand rule, and check for voltage after waiting 5 minutes.
A new course is being launched in the next year. I'll report any new recommendations after we've taken more training on the subject. So far, only the above has been required to be certified in our trade.
Ok but where do you buy the parts
In this case, Hyundai sells the battery modules separately. But battery repair shops have different suppliers.
Please wear eye protection. When younger, I was working on a VW generator, and a short shot a glob of molten metal towards my eye. I was wearing glasses, but the molten metal melted a hole in the lens. Lesson learned !
Thank you, I will do that in the future. I wear a full face shield with anything else in the shop.
Missing a real treat..ISOLATION and TESTING IT...
I will make a video about isolation testing in the future. Right now we don't have the equipment to test individual modules. This battery was condemned by information in the BMS about discharge rates.
I will contact battery rebuild companies next to make a video about testing cells.
Where u located I looking to buy a car that I think has a bad battery..can u help me fix it..or where u located
I personally can not help with the battery, but I have contacted a couple of shops in Toronto that safely do this kind of work. One of them was willing to rebuild a hybrid battery for only $1,200cad. Give me a little bit, and I'll post their info.
@@livewirereview I'm in California tho lol
@joeboyfast7827 Ha! I'm in Canada, so I suppose that won't help. There should be lots of places in California. Some forklift shops in the US even do that kind of work on the side.
6 foot man working off a lift table lowered to the ground. what were you thinking?
🤣 You have a good point! Sometimes, the obvious escapes me. But I wanted the camera to have a good view. Thanks for the comment, it made me laugh.
Hey, you didnt follow the one hand rule when you removed the cover
I had verified 0v at that point, and it's not a current carrying part. For a bigger battery without a PRA inside, you'll need 2 people or a chain with lift points to pull the cover.
More jobs for sparkies in the future
Lots of jobs for people willing to learn! Thanks for the comment.
A geman expert died falling on on of these open batterys ,no second chances
Follow the safety precautions! That's why I slowly reduced the available voltage until it was below 48v DC.
Yes he tripped ans fell on it
Sounds awful, I'm sorry that happened to them.
Even if we find a third party shop to repair ev battery, buying ev battery cells to replace them is very difficult.
I've called a few places in Toronto that do this. So far, there are no supply issues here. We can even order modules at the dealer.
One hand rule, off balance, effeted to eyes and body,.. Two hands rule would be saftier
Would be nicer that way!
Insurance premiums will stop this. EV fires are highly likely to result in more damage that just the loss of the car. Insurers will demand mechanics keeps their hands out of the battery packs and use only factory supplied packs so the liability is on the manufacturer, not the mechanic. If a mechanic starts rooting around in the pack, the manufacturers are going to say he caused the fire with faulty workmanship, not them.
You never know what the future will hold. Unlike tesla packs, these are easy to rebuild.
There is a new course coming out soon on this subject. I'll report back when I take it.
@livewirereview skill does not come into it. It is about insurers wanting to minimise their exposure. Insurance premiums for EVs in the UK have soared with some insurers now refusing to cover them. This is a mature EV market where EVs are being driven and maintained like ICE vehicles. Which is poorly. The risk with a bomb ICE car is breakdown, which insurers do not cover. With a badly maintained EV, the danger is fire and a fire that has the potential to cause serious damage to things other than the car. The insurer is liable for the total damage bill.
Sorry, there are more vehicle fires in ICE vehicles than EV's, by far. After 15 years of attending to insurance claims involving property damage every one was an ICE vehicle. At present there are several recalls from various manufacturers regarding ICE vehicles that need to be parked outside due to a fire risk. At present there is only one hybrid vehicle that has a recall for a similar problem.
That is not to say that an EV fire is better or worse, they are harder to extinguish and need to have certain protocols followed when extinguishing them but they do not pose a higher risk than an ICE vehicle.
@michaellippmann4474 agreed and spot on sir 👏.
@@michaellippmann4474 There are millions more ICE vehicles than EVs. They are on average a lot older and many have been poorly maintained or poorly driven. How many EVs did you see 15 years ago? 2008 was the year Tesla came onto the US market so I expect not many. EV insurance rates have soared in the UK which is a pretty mature EV market. Many more EVs are being driven with the same disregard as ICEs were driven. Concerns of physical or shock damage to battery packs means they need to be replaced after a scrape or bingle. Replacement pushes the liability onto the manufacturer and not the repairer who says the pack is OK. If your employee bangs the battery pack on a gutter and one day it catches on fire, who is liable? The mere sign of a dent will see insurers saying they do not cover neglect even if the fire had nought to do with the dent. Is replacing a dented battery pack an insurable repair or normal maintenance like replacing brake pads? This is the real world those pushing RVs do not mention.
You just sold me on keeping my ICE as long as I can. Have my bicycle, so I don't drive that much anymore anyway.
Matt does the same. He drives an older ICE but rides his e-bike and e-scooter for as much of the year as possible. He saves a lot of money that way without having to invest in an EV right away.
My car battery has been tested 200 000km with 90% battery and original brakes. Saving huge amounts on maintenance. The average life on the Smart EV is estimated 20 years.
@jasonsousa4522 Make sure you keep the 12v battery charged in that car. My neighbour had to replace the main battery due to an issue in the BMS programming that allowed the main battery to die, causing cell failure. Someone left the lights on and the 12v died while it was being stored. Other than that, the car is great 👍! It was under $8000 total for the repairs, including new brakes and some other broken parts.
He is missing a lot of safety gear and tools to be working on Hig Voltage. Like VDE 1000V (or simlar) approved PPE and Tools.
Also, DO NOT BELIVE THAT ONE HAND WORK METHOD IS SAFE. Hi Voltage work is never safe. You can only try to reduse the risk. You will also need both hands to safely remove stuff, without the risk of dropping and shot circuit the battery.
Yes it's true. Our industry is taught only these practices. An electrician has a lot more education and experience in this field. Hopefully some of these ideas will be addressed when the full battery course at Hyundai is released.
Even on evs it's always a 10 mil 😂
Always!
😂 Tesla was the blick bate.
Ha! Just wanted to park inside while I was filming! 😄
@@livewirereview thank for sharing and a side note should have been that there are different battery types like Tesla’s cylindrical and pouch and so on and the way too prolong life and repair is a bit different on each type.
@Top12Boardsport I agree. I am researching ways to gain access to different battery types so I can show more of this content. Tesla batteries are much more difficult to work with. For example, the model 3 uses 4 long modules with foam holding in the cells. That battery is easier to replace a whole module rather than a cell or pack of cells. Regular OEM manufacturers seem to have easier to rebuild packs than Tesla but they don't have economies of scale yet so they have higher replacement costs right now. This will definitely change in the future.
@@livewirereview agree, my family has 5 Tesla cars since 2013 to 2023 and all still original Batteries our latest I a Berlin build with BYD LFP batteries should be easier to repair I hope. But still many miles to go I hope one of our Model S cars has been driven 360.000 km.
@@Top12Boardsport that is amazing news! The LFP should go forever. They get 1000 more charge cycles that the equivalent NCA so that should last.
THIS IS NOT UNCOMMON.
We service many pf these cars and this was the only new model that we've seen with an issue. Only one other car has come through here needing a battery rebuild and that was a 2013 Sonata hybrid with 335,000km.
DANGER DANGER. DANGER
YOU SHOULD BE USING HIGH VOLTAGE TOOLS. NOBODY SHOULD BE REPAIRED A BATTERY ASSEMBLY WITHOUT THE NECESSARY TOOLS. DANGER. DANGER DANGER
They do sell insulated tools, but they're not necessary with the correct precautions. Even in our HV training, we used regular tools because of the gloves and one hand rule. At a certain point in this video, I got to the point where the highest voltage was only 30v. At that point, gloves aren't even required.
All this tells me is dont buy an EV.
Similar to rebuilding an engine but with batteries.
One-handed rule is a complete waste of time. Just check it with a no contact voltage and if the voltage is not there on the case, just work like a normal mechanic.
I am with you! I don't enjoy the one hand rule either. It's just part of HV curriculum here in Canada.
