This is a slightly different use case (charging for people who don't have off-street parking), but I suspect that it will be a good model for out-of-charge rescues as well. It is essentially a mobile rapid charger:

- ZeroGravitas 5y agoI think there was a HN backed startup that did this with gas for cars parked at workplaces. The win was abitraging the price of petrol and the drivers time. If these mobile batteries charge at non-peak periods they can probably replicate that.
- pjc50 5y agoA Tesla with the largest battery pack is 100kWh. UK electricity prices seem to be about 15p/kWh, so that's £15 of electricity maximum. Not a huge amount of room for margin, but I suppose it's in the same range as Uber trips or food deliveries, and small compared to the £50-£100 of a full tank of petrol.

- ZeroGravitas 5y agoThe service in the post I replied to charges £6 per week for up to 10Kwh, so best case 60pKWH, then 37p/kWh for each kWh beyond 10. Which seems reasonable considering fast chargers at gas stations are about 45p/KwH.
