Study: EVs with V2H cut household electricity costs and need for home batteries

But that would accelerate the vehicle's depreciation, which is costly. I suspect it would make more financial sense to have a home battery, they should have compared the prices of home batteries vs car batteries. And for the national grid effects, just charging your vehicle when electricity prices are the lowest would have mostly the same effect but would be a lot simpler.

V2G is what we should focus on. Tens (eventually hundreds) of millions of EVs soaking up free power that is being curtailed during the day, supplying power back to the grid later in the evening at peak prices, replacing peaker plants.

The success of V2H partially depends on it being a technology that’s not just for nerds. It has to be something where the user just plugs in to their house and doesn’t have to think about it. Their energy use is optimized and their vehicle is charged up for the next day.

The other part of this is that all these things sound great, but single family homes with cars as the primary method of transport is a losing strategy for global sustainability. The best way to reduce global oil consumption is to reduce the number of trips people choose to take with cars.

Electric cars, V2H, that stuff is all something of a band-aid compared to building infrastructure that makes it safe and convenient for me to cycle to work or take the bus.

Even in the United States where single family homes are probably more prominent than anywhere else, something like 40% of people don’t live in a single family home.

I'm looking at a new car later this year. The limited options for V2H are disappointing.
