It seems the Tesla-equivalent in the motorcycle world is Zero (by looking at other questions), so I'll focus on this brand for this question (but feel free to correct me here).
Can I charge a Zero motorcycle by just connecting the battery to an AC socket independently?
The motivation of this question is because if you live in a city, it may be hard to find a place to live where you can store the motorbike next to an AC socket whose power can be billed to you properly.
Most of the motorbike owners in my city just let it sleep outside, not even inside a garage. That's a no-no for electric motorbikes, which normally require a night time worth-of-charge. If I could just remove the battery, take it to my apartment, charge it, and come back later, then I could let it sleep in the street as well.
