BYD’s hybrids have quite large batteries (30kWh or more) and electric ranges of >100km, so calling them ‘tiny’ is not correct.

Tiny would be something like a Prius, which does not qualify for a green NEV license plate in China as its battery-only range is not large enough.

Weirdly, even though the majority of Shanghai’s bus fleet is electric, I don’t think any of them are BYD buses (or at least I haven’t seen any) - most buses here are either Sunwin (SAIC) or Yutong.

I must be imagining all the BYDs I see on the streets here in Shanghai, then.

Pretty good. A large number of charging sites are owned by State Grid, the national electrical distribution network. There are large charging sites throughout major cities, and many parking garages for places like malls also have chargers so you can charge while you shop. And almost every rest area on the national expressway network (which is twice as large as the US Interstate system) has fast chargers.
