Tesla is now making more EVs that can double as a home battery
Tesla announced that its Model 3 and Model Y EVs can now provide home backup power using AC bidirectional charging, expanding a feature previously available in the Cybertruck. The system requires a Powerwall 3 battery, costing $8,200 plus installation. Tesla claims this is a more cost-effective solution compared to traditional DC bidirectional chargers. The company is also exploring vehicle-to-grid (V2G) capabilities with utilities like PG&E, CenterPoint Energy, and Oncor.
