Last week, we covered a video dissecting the drive unit of a Chevrolet Bolt EV. The video was comprehensive and informative without drowning the audience in complicated mechanical semantics. Now Professor John Kelly of Weber State University is back at it with another deep-dive video. This time, he’s disassembling the battery unit of the 2017 Chevrolet Bolt EV. Buckle up, and bring paper and a writing utensil for notes, this class will go a little long.Â
The video begins with Kelly making a few corrections and clarifications from a previous video, explaining how DC fast charging works with the Bolt. He also explains how to tell which generation of the battery is found in a Chevrolet Bolt EV. One way is to inspect the VIN to see when Chevy built the Bolt EV. If the Bolt EVÂ was made after a specific date, it’d have the second-generation battery. The other is to look at the coolant connectors at the front of the battery. On the new design, there is a male and female connecting port. The old design featured two female connectors.Â
All this happens in the first five minutes of the video, and it gives you an idea on how detailed Kelly is when he’s explaining the various parts and components of battery unit from the Chevrolet Bolt EV. The video is lengthy with a runtime just over an hour and a half, and there’s little justice in transcribing Kelly’s detailed explanations while he disassembles the battery. You can tell he loves cars, technology, and teaching, and blocking out two hours of the day for some extracurricular learning is time well spent.Â
By the end of the video, Kelly has the entire battery disassembled. All that’s left on his workbench is the battery tray—he even removed the structurally supports and individual battery cells. Do yourself a favor and watch the video. It’s not only a great deep-dive into the Chevrolet Bolt EV, but it’s also a great starting point to learn about electric vehicle powertrains and how they work.Â

These videos are well done, thank you for your efforts professor.
Shouldn’t the title of this article read
“Chevy Bolt Battery Tech Shot Acoss Bow Of Tesla”
After all, GM does fire their own shots.
Just a “Heads Up”.
Another “Shot Across The Bow Of Tesla”!

The battery and powertrain are built and designed by LG.
I have bookmarked your blog, the articles are way better than other similar blogs.. thanks for a great blog
Good afternoon,
I’m curios about the retainer clips that hold the orange High Voltage harness to the metal crash bars in between the battery sections. Those retainers aren’t of the “Christmas Tree” type but the kind with wings on them. How did you remove them and were if they can only come out with force, did you replace them?
Your article is very useful, the content is great, I have read a lot of articles, but for your article, it left me a deep impression, thank you for sharing.
