Have paid a lot for EV seminars and training and this one for free is the most helpful of all. Thank you very much for your work, you make it look very simple, excellent instructor, hundred percent educative and pleasant video. Can't wait for more. Massicve Respect!
Hi Dan, great videos keep on going. Just want to add that there is a reason why voltage is exactly 305 V. The reason is that 220V AC RMS Sine voltage has a peak voltage of 305 V DC value so you can desing inverters and permanent magnet motors more easily and system currents are lower for same giving power. 😉👍
Interesting Video. Back in the 80s I worked on aircraft nicad wet cell battery packs. No individual cell monitoring back then. Each cell was connected with stainless steel jumper bars. What fun taking apart all the cell packs and equalizing each cell. I wrapped all my tools in electrical tape and donned heavy rubber gloves for protection.
I bought a Mk 1 Prius to tear down and learn about Hybrid systems. Have to say I was over cautios when stripping the batteries down and would never use a metal topped bench. great video as usual.
as a beginner tech i truly appreciate and do my best to keep up with your video dan thank you sir , also love the father son hangs all the best from ny!
In typical diagnose Dan videos this one referenced excellent learning opportunities. Good job as always. As a sidenote, for those that do not know I would have explained why safety equipment is required when you work on a hybrid. Then again, if you don’t know maybe you should not be working on it.
A simple yet basic explanation of the power distribution arrangement of DC voltage in a hybrid or a totally electric vehicle. Very informative and well explained, Dan. Maybe it should have been stated that No Load must [not] be connected to the battery system before disassembling the bus bars. Wish the battery manufacturers would provide plastic caps or covers for the battery terminals after the connecting metal strips/bus bars were removed. This would protect the technician if he accidentally dropped or mishandled one of the metal covers that are placed on top of the assembly; and keep potential battery terminal short circuits from occurring. As you illustrated, using the proper insulated tools and personal safety equipment are absolutely necessary.
I’m attending my first EV course tomorrow and already I feel I have learnt so much with these 2 videos! Fantastic quality videos! Keep up the hard work 👍
Dan, thanks for making complicated things easy to understand. Excellent channel on vehicle diagnostics. Thanks for making this great video, Diagnose Dan, Detective Dan, Dr. Dan, Professor Dan?
Now you're in my domain! We call the battery computer a BMS, a battery management system. Because lithium cells go high impedance when they fill up, you can't balance cells by just float charging it the last 10% of the way, so one thing the BMS has to do is balance the cells by moving charge from a high cell to a low one. It also monitors individual cell voltages and shuts down if any cell goes too low, which would damage it. Finally it also monitors temperature for safety and determines the state of charge. For cars a slightly higher energy density of NMC is preferred, Nickel manganese cobalt. For stationary applications LiFePO4 is preferred, less risk of fire and longer cycle life.
@@Diagnosedan It's always interesting to see how car makers implement this. I know BYD (Chinese battery maker) also have an architecture like that, where you have individual (rack-mount) modules talk to a BMU, and the BMU consolidates the information and presents it as a unified battery to the rest of the system. The neatest system I've seen is from Sony (now Murata), also with multiple 1.2kwh modules that talk to a single controller, and you can parallel controllers into the hundreds of kwh levels. So quite established tech...
Your on top the line like always Danny! Thank you very much for this tutorial, you're amazing, can't wait for the next video about cell monitoring modules!
Hi Dan. Another very interesting and informative video. Your presentations always seem so polished...hard to believe you ever have any bloopers! They are always funny to watch. Keep 'em coming my Dutch brother.
Skil used to make a 1/4" drive power wrench that ran on 2 Ii-Ion batteries in series. It had a rachet and the power drive, which was of modest strength. You need one. All this 10 mm nut and bolt removal and replacement is too much. See if you can find one. You'll like it. PS. mine stopped working. I need to fix or replace it. Good video.
👍🏼 Excellent video, especially the safety! As an aircraft mechanic, we were taught never to place batteries (lead-acid types), onto metal surfaces for maintenance or concrete (the latter for long-term storage). Perhaps a piece of wood across your metal lift, or whatever the batteries were placed on during this video, would be safer in case of tip-over?
Hi dan what I know the dc voltage doesn’t kill is that true? If it does at what voltage rates also is that battery dc voltage? I’m pretty sure it’s dc and has some inverter to ac ? Please make videos about it thank you
Dan, since you mention it ac is usually protected ( fused ) at multiple locations and relatively benign in a domestic situation with regard to a short circuit, however it has the effect that you are immobilized when exposed to it in some cases, not all, you just cannot move the affected body part, the muscles spasm back and forth ( from experience ). Dc is different in the way that you get a shock and the muscles move away very quickly and the electrical danger is stopped ( from experience ) however dc is usually not fuse protected inside batteries and all the available energy in the battery is released until exhausted. We may well see fuses of some sort inside battery blocks in the future, you may already know all of this and provide a brief explanation but i thought it important to mention, some is not very well understood. Amazing video, great advice and u are absolutely correct. ( een batterij op een metale werkbank?) Best wishes and respect from N.Z.; max
@@maxsmart5466 actually it's the other way around. You have a chance of releasing a high voltage AC component. On a DC high voltage component this is less likely. Also the AC voltage is a average voltage between the two tops, so the effective voltage is lower. On a DC power source you get the full voltage. High voltage system are also fused in a car but remember you only can take a few hundred miliamps thru your hearth before it's stops pumping, so you'll be dead before the fuse blows.
Hey Dan Yet again another great video and you explain things so well and are a real enjoyment to watch, thanks again for all of your hard work 👍👍👍👍👍 Cheers Lee
When you are using insulated gloves, it doesn't really matter. Using one hand is just an extra safety in case the voltage penetrates the glove somehow. But it's not a bad thing, respect the rules in your country
These cars will b coming into our shops with worn out batteries. Installing rebuilt modules is going to b profitable. The worn out ones sell for cheap. And gasoline is going thru the roof in the states. Dan is keeping us ahead if the curve!!
Hey Dan, Thank you for the lovely demonstration. I work in a training department for a car retailer in Dubai. We are introducing EV and Hybrid vehicles in the market soon. Thus we were looking at safety gears especially high voltage gloves that will be both safe and functional (given that most of the class-00 rubber gloves are very thick and which makes it difficult for the tech to grab their tools). Can you tell us about the gloves that you are using in your demonstration and how good is it for practicals applications. I appreciate your time. Thanks Asfaq S
I get a real charge out of these videos. I'm positive I'll learn something but I fear some comments might be negative. Resting any tool on a battery is a bad habit regardless of anything. I'm still a fan tho 😀.
Hallo Dan! En is het mogelijk om deze module volledig te demonteren met batterijen? Interesses prizvoditel,gs yuasa or panasonic ?, evenals de capaciteit van elke cel. Bedankt. En ik zou graag een recensie zien over het remsysteem.
Hi Mr Dan I'm from Iraq thank you for your effors in providing education and training to develop the capabilites ot the others . i have question .when i use scan tools some codes show numbers only for example 00,65,85,66 .what does that mean ? thank you
Hi Dan, great series so far. One very quick question, when you were removing the bus bar, you used the snap on ratchet but what looking like a normal black metal socket, don’t you need one of those orange insulated sockets? Cheers. Looking forward to the next video.
Nice one again Dan, look forward to seeing the battery components further stripped down. Out of interest can you individually replace battery cell packs on this model?
Amazing the multiple levels of connection. Are the modules and cells labeled so that from the scantool you can already identify which of the modules you need to remove and open to get to a specific cell?
Very interesting exploded view and component description. However, as a factory trained technician, I promise every technician watching that you will NEVER be servicing an HEV battery and there will NEVER be a need to disassemble it.
Nice thorough explanation. Learn by doing. Thank you. But I am still afraid of my Highlander hybrid. Some regions are simply Verboten. 500 V and 200A would cook me like a electric chair.
Super video,thank u Dan.One question Dan,my friend has baugt tesla S 2013,this car was brought to europe from amerikan auktion(he did not know that) ,now he cant apdate the cars software,the last apdate was in 2017,as i have found aut,this car is in so called black list in tesla sistem,it means,he cant apdate it,because it was rapaired not in tesla service,do u know if there any possybility to unlock this car,so that he can apdate it without problems,thank u Dan.
I'm learning lots, thanks!
Thanks Thomas!😊👍

I hope you will have a video on all parts of a hybrid not only on the batteries because this kicks ass! So great!
Will do!👍
The moving parts aren’t really that complex but that would be a cool video
Hi Dan, great videos keep on going. Just want to add that there is a reason why voltage is exactly 305 V. The reason is that 220V AC RMS Sine voltage has a peak voltage of 305 V DC value so you can desing inverters and permanent magnet motors more easily and system currents are lower for same giving power. 😉👍

Wow that's interesting!
Wow. As a backyard mechanic, you taught me so much in one video. Thank you
I bought a Mk 1 Prius to tear down and learn about Hybrid systems. Have to say I was over cautios when stripping the batteries down and would never use a metal topped bench. great video as usual.
A big THANK YOU...from all DIY mechanics..keep teaching us..God bless you..
Thanks for watching!
Loving this series Dan, breaking it down to the simplest parts takes the fear and mystery out a complex system. Keep it up bro!👍🏻😎
Exactly! That's what I'm trying to do!
You're an excellent instructor on so many levels Dan! Thanks for putting together such an amazing series like this!
Thanks for watching my video's it's appreciated
@@Diagnosedan ofcourse I'm excited about future PEHV videos 🙃👍
Awesome video as always! One thing we do where I work is always disconnect the middle bus bar first to halve the voltage, then do the rest as needed
Disconnecting the service plug usually already halves the voltage
DiagnoseDan another great video. The educational experience you've provided is a great
Thanks Michael
Absolutely brilliant presentation my friend. Thank you for your time and effort.👍
Thank you Sir😊👍
as a beginner tech i truly appreciate and do my best to keep up with your video dan thank you sir , also love the father son hangs all the best from ny!
You're the BEST. You may consider to be a technical teacher also.
Dan -- Excellent video !!! There are a lot of questions from the public and other techs on this.
Thank you!

Another great vid Dan. Love the way you explain things in detail without rushing. Can’t wait to see more. 👊🏻
Thanks!
Very interesting and fascinating. Now I also have an idea of what's things like inside a hybrid car's battery pack.
Excellent! I believe here in New Jersey batteries are covered for 8 years (an extended period) to help the consumer.
That's great!

I want to learn it too pls how can I locate their company. I’m Michael from Ghana
Very impressive battery layout and containment.
What an interesting video! The extent of depth into the battery was brilliant! Excellent video Dan!
Thanks Cuba😊👍
perfect lesson for all of us ,who want to learn .....thanks a lot Dan
This is a great series, Dan. Very educational. Thank you!
😊😉💪👍
That's what we need as a guide to learning things by their perfect rules you re legend.👍👍
I am fully " charged" with more knowledge about Safety around HIGH VOLTS! Thank you sir.
😊👍
Dan, thanks for making complicated things easy to understand. Excellent channel on vehicle diagnostics. Thanks for making this great video, Diagnose Dan, Detective Dan, Dr. Dan, Professor Dan?
Excellent demonstration once again Dan, thanks again! and great to see your blooper's keeping it real.👍
My entire life is a blooper😂😂
after watching this video.. I decide to connect as many battery in series and tide the both end together.. Dan was my teacher
😂😂😂👍💪
Danny this video is incredible... amazing job for sure ☝️😎
Great to see new uploads from you. Keep on with the great work! Your channel is amazing!
Thanks!👍😊
Always learning something new from watching your videos, thank you.
Thanks Neil!
brilliant ,i for one never knew the inner workings of these batteries so thank you for the fantastic detailed insight
😊👍
dan these are great videos love watching your channel learning a lot about cars you are a great teacher thanks again

Thanks Lee!
Amazing quality content ! Thank you Dan! Maybe it's just me, but each time Dan said "Mitsubishi", i got a big grin on my face :)
Great information thanks. I was always told only try and use one hand when using a meter with high volts but thanks for the great video.

Great video Dan! Keep them coming! Great explanation! nice and in depth!!
Thanks!
Easy so far. Thank you Dan for the lesson.👍
It's easy!
Loving these EV series of videos Dan. Keep them coming please?
Sure no problem!

This is a issue at the moment and i don't know of a solution.
