>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.)
