Thank You! As a developer of electric drive off-highway mining trucks, I really enjoyed the detailed explanation and your attention to detail. It's fascinating to see how other engineers solve similar problems. I liked the plastic bus-bar holder that aligns everything for attachment to the individual packs. What a great idea. Never would have thought of that were it not for your video. Thank you again for all the work and effort required for producing these videos. They are unique and unrivaled among the available teaching tools on the internet and speak highly of Weber State

But this is a deep-dive; we don't gloss over anything. So here's the diagram of the module numbering, and here are the stickers that give each module's number. For those of us who are simply here to further our understanding about things in the cosmos - the entertainment of learning something, and will never use any of it in practice, it's nice to *really* see how everything goes together. Even down to fastening the screws and nuts on the bus-bar. Thank you for all the detailed work that you do; it really is appreciated.

Nissan corporate fought me tooth and nail on repairing the battery until it finally when into turtle mode and threw the check engine light. The dealership was on my side, but Nissan corporate would not authorize the repair until it completely failed. They dropped the pack, and replaced the two modules. After it was repaired, I traded it for 2017 Chevy Bolt.

Thanks you for another very informative video! All these high current connections remind me that when I recently replaced a Tesla Model 3 pyro fuse there was a requirement to do a 4 wire resistance check (45 and 60 micro-ohms max) of the finished connection. I can imagine that the Tesla, using plated aluminum connections and max. charging loads of 250 kW is maybe a bit more concerned about this than others, but it made me wonder if we want to be doing such measurements on all high current connections? After all, the consequence of a high resistance connection might be a fire in the battery case and I can't imagine any way that the BMS will detect and prevent such an event ahead of time. In my EV conversion work, we often just give the car a hard drive and then view the system with an IR camera. But in a closed battery case that's not a simple option. Anyway, just the usual musings. Thanks again for sharing so much excellent knowledge on EV's, I've learned many tidbits from your programs.

Hoping that the technology will become less complicated in the coming years so that it comes down to the level of small time Electrical suprevisor's acumen may be able to do it just as a small mech is able to do it with combustible engined cars.

Service disconnect AFAIK is between front stacks and rear stack, dividing voltage in half.

Yes, you are correct. I was wrong. It divides the rear stack from the two side stacks.

Awesome stuff. So many videos are condescending and assuming and this video is fresh air in comparison. A video thats back to basics and gradually educates from the ground up. Very knowledgable and instructional just like being back at school. I understand EV technology in theory but never had a practical. If I ever got into battery servicing I would build a cable testing jig and eliminate problem cables rapidly but that’s another story. Thank you, it was a rapid learning curve and well presented.

Hello from Estonia, again. I have 2014 Leaf, same battery design, different chemistry. Climate here is mild. Two days ago I passed 161xxx Mm (or 100 000 miles) and my battery SOH is 93% (maybe 92% because calculations in cold weather are not very accurate by BMS, it fluctuates seasonally). What I want to say to everybody who really things every battery has to be cooled - NO. No it doesn't. Though chemistry must be totally fine with 20-40*C. 2011-12 Leafs did not like 30*C AT ALL. Also cooling is definitely required if charging happens on average, above 35kW (long distance trips). 24kWh battery will accept 40-45kW for aperiod and gradually slows down to 35kW at around 2/3. 30kWh Leaf can easily take 45-48kW for majority of charging session and THERE you need some active cooling (doesn't have to be liquid). But yea, not all EV's need active cooling :)

Did you know Tesla heat up the battery to 60 degrees to charge and this prevents degradation when charging. This issue with the leaf battery is heating and cooling.

Opening the cell module reminds me when you've disassembled another thing that was not supposed to be disassembled, the grill shutter motor of the Toyota Prius 🤣 but the tool in that case was much more common.
