That's the whole issue with grid and smart grid, what is the true price of electricity? :)
This is all software controlled, all new cars in Europe have a SIM card (eCall law), electric cars are computer on wheels, nothing is missing but the will to do it.
My Tesla model 3 SR+ has 50 kWh of NCA batteries with about 1000-1500 cycles, so about 600k km (to 70% of original capacity). Petrol car leave the european market with about 200-250k km on the odometer (source: discussion with a car journalist).
If you buy a Tesla model 3 SR+ right now in Europe it's made in China with LFP chemistry which is much more durable 3000-6000 cycles to about 2 millions km.
That gives plenty of room to play with car batteries without too much detriment.
And I assume you'll be able to limit discharging to some value to avoid getting stuck on your parking :).
- overscore 6y agoIn Ireland, eCall was only accepted on the condition that it only ever be used for ACR and no other purpose, so I don't think we'll see any EU standards using that eSim for charge control.
- guerby 6y agoI don't think for example my Tesla model 3 has two distinct SIM one for eCall and another one for other data. Do you have a link to Ireland law about eCall? In Europe GDPR force to require consent for personnal data use like most car data is, once consent is given I see no reason not to use the already present SIM for eCall for other purposes.
