Your Polestar EV can now power your house-and save you money
""Most of our cars sit in driveways more than 80% of the time," says Dcbel CEO Marc-André Forget. "Now, for the first time, if we think about it, cars start to be useful even when parked. This is transformational. It's the second-largest investment for most family after the market of the home, and those assets are underused.""
""Should I charge the car right now?" Forget says. "Should I supercharge the car? Should I wait and charge later? Should I use the energy from the car to power the house, to basically avoid buying energy from the grid at a very high price?""
""(The tech can also double as an inverter for solar panels, though if you already have a solar inverter, it likely doesn't have the right software to work with an EV.)""
Polestar 3 now supports bidirectional charging through a partnership with Dcbel and its Ara home energy station. The Ara analyzes energy prices, forecasts household and driving energy needs, and predicts solar generation when applicable. The system uses that data to decide when to charge, when to supercharge, and when to discharge the vehicle to power the home and avoid high grid prices. The Ara converts DC from the car battery to AC for home wiring and can function as a solar inverter if compatible. Polestar and Dcbel collaborated for 18 months to create an automatic, app-monitored user experience that also provides outage backup.
