A bit more technical detail from greencarreports. I was wondering if 800v charging necessarily implies anything about motor voltage, and apparently it’s “sometimes”.
GM’s GMC Hummer EV, for instance, runs at 400 volts, and each layer of its dual-layer battery pack operates in some ways as an individual pack. In 400-volt charging, the packs are connected in parallel, but for 800-volt charging a switch allows them to be connected in series—like the cells in a long, multi-cell flashlight—to take advantage of the higher voltage.
That 800-volt “trick” permits the Hummer EV pickup, with its 205-kwh battery pack, to charge at 350 kw and gain nearly 100 miles of range in 10 minutes—despite its 400-volt system and its inefficiency compared to other EVs.











Why is this better than the scripting environment in other CAD systems? I’m particular, I looked a bit at https://openscad.org/ previously, though didn’t make much headway modeling the thing I wanted.
Why is a language-level approach better than just an API in an existing, popular language?
