Affordable EVs as home power banks

Mass‑market electric vehicles that include onboard bidirectional inverters turn cars into household energy assets, able to supply ~10 kW of AC power for outage backup and peak‑shaving. By building inverter hardware into the vehicle and pairing it with lower‑cost home controllers, automakers can make vehicle‑to‑home (V2H) and vehicle‑to‑grid (V2G) features affordable for ordinary buyers. — If EVs become cheap, integrated home energy resources, they will reshape residential backup power, electricity peak demand, grid planning, and the economics of household decarbonization.
