Tesla Enables V2H Bidirectional Charging, Europe Completes EV4EU Trial
Tesla has enabled vehicle-to-home (V2H) bidirectional charging for US-built Model 3 and Model Y vehicles from October 2026, requiring specific hardware. The feature allows cars to power homes during outages, with a Powerwall 3 battery. Europe's EV4EU trial demonstrated V2G technologies' benefits, including grid stabilization and renewable energy integration, with cost savings and increased renewable use.
