But why involve your car? The logical thing to do is install a large lead-acid battery pack for the house, one which is dirt-cheap and won't suffer being charged/discharged. Lead acid batteries of a capacity equivalent to a Tesla can be had for a few hundred dollars. Lead-acids are also infinitely recyclable and don't involve the nasty/complex chemicals of lithiums. The ideal system would be to slowly charge the massive house battery whenever power is cheap, then dump it into charging the Tesla without drawing from the grid.

- Gibbon1 4y agoMy company tried designing a unit that runs off a solar panel and battery. We initially designed around a lead acid battery. And as we kept accounting for things it just got larger and more expensive. We then switched to a lithium ion battery and it's literally a 1/3 the cost and a tenth the weight/size.

And yes, V2H power can increase wear on the battery, but my understanding is that large strides have been made (and certainly will be made) in reducing the wear impact on the battery.
