I just watched this terrific tech talk from Lucid Motors CEO Peter Rawlinson. He does a great job explaining both the basics of electric vehicle battery packs and also some of the tricks Lucid has turned in order to push the technology forward.
Rawlinson incorporates just enough basic physics to ground the explanations in reality. I really appreciated that he took time to explain different approaches to battery pack configuration, what the trade-offs were between approaches, and why Lucid took the approach they did.
Before joining Lucid in 2013, Rawlinson was the Vehicle Engineer on the Tesla Model S.
Frankly, the whole tech talk is worth a listen simply to hear Rawlinson, who is originally from Wales, say “foot garage.”
