Wow. As a backyard mechanic, you taught me so much in one video. Thank you

I hope you will have a video on all parts of a hybrid not only on the batteries because this kicks ass! So great!

The moving parts aren’t really that complex but that would be a cool video

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.

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. 😉👍

You're the BEST. You may consider to be a technical teacher also.

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...

A big THANK YOU...from all DIY mechanics..keep teaching us..God bless 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.

You're an excellent instructor on so many levels Dan! Thanks for putting together such an amazing series like this!

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.

Another great vid Dan. Love the way you explain things in detail without rushing. Can’t wait to see more. 👊🏻

Your videos are awsome, Your channel is awsome, I literally will watch and like every video over summer

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.

Great training video .Thank you

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.

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
