    Depends.

    If you have, say, a 75kWh battery, that’s 3-4 days of average summer usage in a large house.

    So if you use it to shave off peak usage costs from 4 to 9 pm and then you top it up off peak again from 1 am to 6 am, you cycle through about 10-20 percent of it’s total capacity. If you kept doing this in the mid-range of your battery , like 55-75 percent, it would have a negligible effect on battery life.

      Also consider a car probably sucks a lot more current from the cells than a house (while accelerating). Batteries are much happier about low current draw so it’s probably much milder wear than driving the car for the same amount of energy
