I'm learning lots, thanks!
Thanks Thomas!😊👍
High value channel free of charge! Thank you professor! 👍
100% Free😊👍
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!
This guy explains better than the teachers I had in school .
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. 😉👍
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.
Wow that's interesting!
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 🙃👍
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.
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!
DiagnoseDan another great video. The educational experience you've provided is a great
Thanks Michael
A big THANK YOU...from all DIY mechanics..keep teaching us..God bless you..
Thanks for watching!
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.
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
Dan -- Excellent video !!! There are a lot of questions from the public and other techs on this.
Thank you!
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.
What an interesting video! The extent of depth into the battery was brilliant! Excellent video Dan!
Thanks Cuba😊👍
Another great vid Dan. Love the way you explain things in detail without rushing. Can’t wait to see more. 👊🏻
Thanks!
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!
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 👍
Good luck!😊
I want to learn it too pls how can I locate their company. I’m Michael from Ghana
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?
Very impressive battery layout and containment.
Absolutely brilliant presentation my friend. Thank you for your time and effort.👍
Thank you Sir😊👍
This is a great series, Dan. Very educational. Thank you!
😊😉💪👍
You're the BEST. You may consider to be a technical teacher also.
Great to see new uploads from you. Keep on with the great work! Your channel is amazing!
Thanks!👍😊
Excellent! I believe here in New Jersey batteries are covered for 8 years (an extended period) to help the consumer.
That's great!
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.
Even if you never open it, it's good to know something about the fundamentals. Thanks for watching my video's it's appreciated
I am fully " charged" with more knowledge about Safety around HIGH VOLTS! Thank you sir.
😊👍
Excellent demonstration once again Dan, thanks again! and great to see your blooper's keeping it real.👍
My entire life is a blooper😂😂
Another spot on video Dan! Very informative.
Thanks!
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.
Thank you very much for taking the time to watch and comment! It's appreciated 👍😊
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.
Thanks!
Always learning something new from watching your videos, thank you.
Thanks Neil!
Good stuff Dan, keep up the good work!
Thanks!😊👍
dan these are great videos love watching your channel learning a lot about cars you are a great teacher thanks again
You are welcome!
Very interesting and fascinating. Now I also have an idea of what's things like inside a hybrid car's battery pack.
perfect lesson for all of us ,who want to learn .....thanks a lot Dan
after watching this video.. I decide to connect as many battery in series and tide the both end together.. Dan was my teacher
😂😂😂👍💪
Another great addition to the series Dan 👍
Thanks!
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 😀.
I'm only human😂
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!
😊💪👍
Thanks for the thorough training, Dan !
Your welcome!👍😊
Excellent Dan your are the best tech and also Profesor, a PHD !!
brilliant ,i for one never knew the inner workings of these batteries so thank you for the fantastic detailed insight
😊👍
ЧУДОВЕ ВІДЕО. ДЯКУЮ за ПРАЦЮ.✌👍
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.
I'll talk about cell ballancing, temperatures in the next video. This car also has a BMS that is in charge of the 10 CMU's
@@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...
That's what we need as a guide to learning things by their perfect rules you re legend.👍👍
👍🏼 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?
Danny this video is incredible... amazing job for sure ☝️😎
Seriously if these mechanics wanna survive the future they should start buying books and watching channels like this good stuff
Thank you Dan for all that videos. EV is the future !! Thanks for sharing
Your welcome!
Dan , once again a fantastic lesson . I really appreciate the knowledge you share, keep it up 👍
Thank you!😊👍
Your videos are awsome, Your channel is awsome, I literally will watch and like every video over summer
Keep those vids coming Dan! Really enjoying this series. Even I was breathing heavy watching it. haha
😂😂👍💪
looking forward to the next video! Fantastic work.
Thanks!
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 job Dan! Thanks & please keep those videos coming!
Sure!😊👍
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
Thanks Lee!
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!!
💪💪💪Thanks Bill
Loving these EV series of videos Dan. Keep them coming please?
Sure no problem!
Sure no problem!
Great video Dan! Keep them coming! Great explanation! nice and in depth!!
Thanks!
Great video and great explanation as always Dan thanks for your efforts
Your welcome!😊👍
Thank you for sharing about high bread unit sir dan.
Thanks Dan, your videos are greatly appreciated.
Thanks!
Very well done, Dan. I learned a lot.
Thanks!😊👍
Its old science and New science for car hybrid. !!! Thanks Dan for thé New vidéo .
Your welcome!
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.
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
Hallo Dan,
Super video erg leersaam
Ik hoop dat je er nog meer maakt over elektriche voertuigen
Meer onderweg!😊👍
Informative series Dan!
Thanks James!
very nice vedeo sir your all vedeos till now i watch all r amazing sir
Thanks!
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.
Great Job 👍
professor Kelly 😷
well done Don great video as always i do enjoy them

Welcome!😊👍
Good job Dan! My eyes glazed over a bit but still enjoyed it .... 😳😂😂😂
😊😉
Knowledge and experience is a very powerful tool for Learn..thanks @diagnosedan
Keep the vids coming they are very informative many thanks.
No problem!
Tnx for sharing knowledge diagnose dan
Great job again like always
Thank you!👍😊
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
Another great video. Thanks Dan.
Your welcome!
I like this video series, could you entertain us a bit more, like introducing little bit of sparks by "accidental" drop of spanner or something similar please?
Let me think about it!🤔
Don't do it....there are so many amps the tool would vaporise and deposit a silver layer on your face. I mean it would be very entertaining but you would do it only once. The lithium battery has a very small internal resistance....one reason it can deliver insane amps.
I know Lithium-ION's are so DANGEROUS! I'm glad their being replaced in newer cars (as of this note 2022), with other materials...
Absolutely brilliant stuff. Thank you
Thank you Dan for this masterpiece. It is amazing to see how each individual cell can power up an EV.
I'm very curious now on the tools you used in this video, specially on the Snap-on VERUS Edge. Will you be so kind and make a video on this tool and how to use it on EVs? Thank you so much!
Get Matco Tools version. Same quality but a little easier on the pocket book
The real fun starts in a Model S or Model X battery, where you'll find north of 8000 individual cells.
I would love to get some insight into the BMS of Tesla, which is most likely the most sophisticated on the market.
I am learning lot's thanks ☺️ sir god bless you
Another great video Dan
Thank you!😉👍
