Do you currently just use level 1 charging, or not at all?

Most EVs charge at about 3mph from L1, and if you're on-plug for 10 hours overnight, hey, that's longer than a lot of people commute in a day. Might be able to keep your SoC pretty high with that alone.

Of course L1 is too slow to be useful for sharing, but for a resident it often works out quite well.
