Could a HV Battery kill you?

This is the third and final part in my High voltage battery series.
In this video we talk in high detail about the components in a high voltage battery and disclose all its secrets.
Battery used in the Video came from a Mitsubishi Outlande PHEV.
I hope you enjoy this video!

[@themechanic6117]

Tons of work went into this . Thank you. I could see this series being used in a classroom environment.

[@Diagnosedan]

It was alot of work but i hope it helps!

[@parochial2356]

Yes, a lot of work. I'd imagine maybe 2-3 days of work with shooting & editing, not including the animations & narration? Dan, care to comment?

[@emilschw8924]

Guys like Dan and South Main Auto really are good teachers for the rest of us bumbling amateurs :)

[@gasgas2689]

@@parochial2356 Not only the shooting and editing, that was nothing compared to the preparation of the battery pack, and even longer I imagine was the time taken to learn all this stuff. I reckon the manufacturers must take 4 weeks to train technicians with all this knowledge that Dan gives in the video.

Thanks Bill!

[@NewStore-ti2md]

Very good explanation which is structured .No single word irrelevant to the lesson. Clear English pronunciation and even asian's can understand. All the very best. From Sri Lanka

Dan unreal the 3 videos on this ev battery unit...the ultimate teacher ...super teacher as always and great explaining through electude..diagnose dan fixed it again..our brains that is 😎😎

[@Diagnosedan]

😂😂Thanks!

[@jamiemurphy6644]

We must get a video of sun mcs 2000 sl..

[@gasgas2689]

That is brilliant, Dan. Apart from the education on how it works, it was confirmation that I do not want a hybrid car! I already had an electric Leaf for two years and I don't want another electric car either!

[@jesusbenito5389]

It is amazing how you explain things to make them simple. It is the best video I have ever seen about how a hybrid vehicle works!!! You are a great professor and should be giving lesson at university!!

[@Adrian-uc2kp]

Because I'm @ home with a broken foot I started binge watching your video's and in between also other diagnostic channels. Danny, you produce by far the best video's! Very clear explanations, sound & light always perfect, a lot of thought put into it! Great job! Respect! I have learned so much, what a pity there are only 42 videos :-)

[@Diagnosedan]

Wow thanks and i hope you get well soon!👍

[@mikechiodetti4482]

For training on a Prius, the instructor separated our group into two groups. Before Lunch, one group made safe and removed the battery pack from the vehicle. The other group made safe and removed the Inverter Assembly from the same vehicle. The instructor removed the battery covers and removed one of the cells. Then he removed the Inverter cover. He then explained what went on inside. Then we put the covers back on, reinstalled the Inverter and Battery pack. We then verified the vehicle started, ran, and no codes were present. After lunch, the groups reversed their positions on the second vehicle, removing the battery pack and inverter assembly. Again battery covers and inverter cover were removed, parts identified, reassembled, reinstalled, vehicle started, and no codes. Time in the shop on two vehicles including lunch hour, 6 hours. Time in class room, 1 hour. MY KIND OF TRAINING!

[@usethenoodle]

Nice series Dan. I have always wondered about the battery systems on the highbred vehicles. I understand they cost something like $20,000 to replace and that their life span is only around 8-10 years. It seems the wrecking yards will fill up fast with these expensive vehicles as their expensive batteries go bad. Frankly, I just don't see the economy in it. Not to mention all the small sensors and such that can fail. I'm just not behind it yet. To buy an expensive vehicle only to toss it in the dump 8-10 years later seems like a terrible idea. My last car was a 1999 Ford Crown Victoria which I had for 20 years. It was still immaculate and running great when I sold it recently. It cost a fraction of what an Outlander costs and will run another 20 years if taken care of. I still feel internal combustion is the most economic idea to come along. The electrics just aren't there yet.

[@flok1971]

Ik wil alles leren Danny! Ik heb een inhaalslag te maken t.o.v. de jongere generatie. Ik stam nog af van de LTS in 1988. Ik hou mij wel enigszins op de hoogte, maar zonder werkgever in de autobranche , loop ik voortdurend achter de feiten aan. Daarom ben ik jouw zo dankbaar voor deze filmpjes.. Dank je wel Danny!

[@scotthayward1017]

Great Videos Dan . The more PHEV vehicles you diagnose the more interest I have . Hope there is more to come on inverters and other components linked to these systems . 😃

[@ohenenorb]

I have been servicing high voltage power inverter battery banks , and now have upgrade to HEV traction battery and auxiliary. Your series have been very good lessons to me . I will like to receive any and all updates on your tutorials .

[@andrewhallett-patterson9778]

Thank you Dan for this fantastic but way too short series. Your knowledge and clear descriptions make a complex subject understandable. I hope there are more in the future.👍👍🇦🇺

[@Diagnosedan]

No problem thanks for watching my video's it's appreciated

[@nbrowser]

This is better EV education than what they provided in a paid school course I took when I was obtaining my Red Seal Automotive Service Technician certification here in Canada. Dan, thank you for your hard work on this AND answering the title question very quickly into the video.

[@PaulysAuto]

Damn Dan, your videos are so damn good! I cannot imagine how much time you put into making these, but it's probably a lot and super exhausting. Fascinating stuff Dan, love this educational stuff you're doing...VERY HELPFUL! Thanks for putting this together for us and I wanted to let you know how much I appreciate your content! I hope you continued success and wish you all the best my friend!

[@Diagnosedan]

That's a great comment, thanks buddy!👍👍👍👍👍👍👍

[@PaulysAuto]

@@Diagnosedan you bet, when someone is doing great things it is something that should be recognized. I just wanted to let you know that you have many people out here watching you and every now and then it's nice to know that all your time and effort in putting this together is noticed! That is why I hope you enjoy great success for it, IMHO nothing is more nobler than a man who has a genuine desire to help others learn, except for laying down ones life for another; which in a way you do with sacrificing your personal time...so thanks for that Dan!

[@diesalweasel]

from watching all 3 videos i feel like a fully qualified ev tech . i want to learn more on this subject please from you . many thanks for your time and information my friend

[@a.a.8572]

Hello Dan! Glad to see that you are back with a new video.

Thanks for watching Daryl

[@sajanaabeywardana9725]

Best series ever! Hope you'll do these kind of informative videos again and again. Good Luck

[@madds6678]

Great video Dan, nice to be able to see the contractors, interlock & cell monitors up close. Really found the cell balancing part informative & thanks for stating not to rely on the contactors definitely being open as I stated in a previous post ( safety first) . Look forward to more EV videos but a few real world engine diagnostics videos in between would be appreciated . Keep up the great work 👍 Madds.

[@Diagnosedan]

Sure no problem!

Brilliant series of videos. My first exposure to PHEV functionality and most illuminating. Thank you!

[@tubeDude48]

This series was worth watching...Thanks Dan! 👍

[@nomebear]

This is a great video for someone who's willing to give it a try. Where I live a Toyota Prius with a dead battery can be had for cheap. Sometimes it's just one or two cells that are weak, or there might be corroded contacts. For someone doing doing their own repairs parts are readily available and cheap.

[@davidmccrudden3197]

Great video, excellent delivery giving a comprehensive and full understanding of this system. One question though Dan, could the metal undertray not have been repaired and the system refitted saving the cost of a whole new HV battery pack?

[@carlosmaurencig6763]

Great video, Danny! The inverters are a very good subject for videos

[@Diagnosedan]

I'll keep that in mind

[@malgailany]

Interesting to see this level of details of the electric car components. I wish you can show more subsystems of electric vehicles, as these becoming popular on the streets nowadays. Great animations, thanks.

[@Diagnosedan]

Sure no problem!

[@myfastcars]

Shows the need for more underbody armor on EV vehicles.. What was the end result for the old damaged battery pack assy?? Was it a turn in for a core item? If so, what was a core worth? If not, its a great source for Solar battery storage. How much is a new replacement battery pack? FANTASTIC training video.. Excellent instructor skills.

Great!👍

[@BLARNEYBLARNEY]

Excellent series Dan, very informative. Noticed you were doing your disassembly on a conductive diamond plate bench. For safety’s sake, you need to work on a non- conductive surface. While the voltage is low, shorting a battery or even a single cell on that surface might be “exciting” and also possibly component destructive. Keep up the great work.

[@Yulian.Mladenov]

exactly that was one of my questions,after we disconnect the HV battery pack ,is still current on the HV connection of the battery pack? And the answer is ,No. and i learned that from this video. thanks a lot 🙏, continue like that,great job!🙂

[@ozzstars_cars]

Fantastic video series Dan. Thanks for taking the time to share your knowledge on HV batteries. I am wondering why the entire battery was changed instead of just the protective cover?

[@Diagnosedan]

Thanks Glen, The reason the battery pack was changed is because first of all water has been in the battery and second, Mitsubishi doesn't want you to repair these batteries yourselve so you can only order the full pack and no parts.

[@Yulian.Mladenov]

Great job Mr. Dan!Bravo. Your videos are very very useful for me, because now I'm learning and working on EV buses which use the same technologies and your videos are answering of many my questions. thank you very very very much. i really enjoy.❤

[@-robster-robster-]

I agree. really unselfish sharing of knowledge that is very rare , usually you get guys that get really good at thier trade and hold back the information so they have the technical edge or a sure income type of repeat job , its an ego and self preservation / job security trait that can be understood e.g say you do a niche job not known to many then you go on youtube for fame and spill all the information letting everyone in on the job you have taken months and years to learn and make a viable business, then over night everyone is fixing thier own stuff and make yourself obsolete

[@Diagnosedan]

No problem Peter!😊

[@inhocsigno9151]

Nice video. PEHV vehicles are so complex, must be expensive. Hopefully the entire battery pack did not have to be changed. I would consider soldering the gash in the pan to seal and coat it, then replacing just the damaged batteries. But I don't have a lot of money. DC voltage makes muscles contract so a person grabs any exposed high voltage part and can't let go. It only takes a few ma thru your heart to stop it.

[@edwindilag4470]

Yes please. Make more videos on the inverter, charging system, and electric motor for electric vehicles.
