Polestar is moving fast to bring bi-directional charging to its electric vehicles. Recent tests in Europe and Australia show strong progress. The Polestar 2, 3, and 4 all support the technology during controlled trials. These tests confirm that the cars can send power to homes and even back to the electricity grid.
In Germany, tech company Ambibox tested the Polestar 2 and reached a discharge output of 6 kW. The Polestar 3 and 4 went higher, delivering more than 10 kW. In Australia, RedEarth Energy Storage also tested the system. Their setup reached 11 kW, which suggests strong performance under real conditions.
Major V2G Project in Sweden
Polestar’s largest move is now happening in Gothenburg. The company launched a Vehicle-to-Grid (V2G) project using a virtual power plant. The system links Polestar 3 vehicles to the grid. It chooses the best time to charge or discharge based on energy demand and pricing. This setup helps stabilise the grid and can lower energy bills for drivers.
Smart Charging App Expands Features
In Europe, Polestar is rolling out the Polestar Energy app. The app selects the best charging time based on electricity rates. It will later support full bi-directional features. Polestar plans to launch the home wallbox needed for V2G and Vehicle-to-Home (V2H) in late 2025.
Looking Ahead
Polestar wants its cars to work as mobile energy storage units rather than simple transport. With more renewable energy coming into the grid, this extra flexibility can reduce strain and improve efficiency. If these trials continue to succeed, Polestar may become one of the first global brands to offer large-scale bi-directional charging for everyday drivers.
