> Pre-heating an EV cabin before departing
Cars have been doing this for a years now with a keyfob. But I suppose over network/cell gives you greater range.
> Turning charging on and off via lets you take advantage of low electricity rates.
I would have thought that'd be a feature of the charger, not the car, but not an EV owner so maybe I'm just wrong here. That does make more sense for an app, but also sounds like a feature that could work fine without one too.
