We bring you the fifth video in an ongoing, in-depth study of the Chevrolet Bolt EV battery and electrical systems.
There’s arguably no one better than John D. Kelly at Weber University when it comes to deep dives into batteries and electrical components of today’s EVs. This is, of course, barring our own George Bower and Keith Ritter, who love to work their models and help us decipher the facts. For those highly interested in the subject, this video series is a must. In the fifth video from Kelly’s ongoing analysis, he takes a more detailed look at the high voltage system in the Chevy Bolt and how its nine individual components work together.
Yes, not unlike Kelly’s previous videos, this is a long one likely geared toward those with specific knowledge of the subject and the need to get into the nitty gritty. Still, it’s not as lengthy as some of his previous shares. Grab the popcorn and carve out about a half an hour to take it all in.
Do you pride yourself on extensive knowledge of EV and battery tech? Please share your wisdom with us in the comment section below.
