>energy already stored in the car's battery can power home electronics at night.

Will those extra charging cycles shorten the lifetime of my EV? It's one thing to have household batteries, which can be replaced on their own and which are still pretty useful at 40% of their original capacity. But I can't economically replace just the battery on my EV (it'll cost more than the car is worth) and diminished range would really reduce the utility I get from the vehicle it powers.

(But thanks for getting me thinking with that list, regardless.)

Not realistically.

EV batteries are anywhere from 40->120kWh in capacity. The average home consumed consumes around 20 to 30kWh a day. Assuming you pair your EV with a solar you aren't likely using a significant portion of the battery throughout the night.

This does depend on the chemistry. If your EV is using LFPs, you have about 10k cycles to play with. NMC has about 1000.

So, for an LFP vehicle it's practically a no brainer.
