- Polestar and Clever are testing V2X tech in selected Danish homes using Polestar 4 vehicles.
- Pilot explores charging when electricity is cheaper or lower-carbon, then discharging during higher demand.
- Polestar has not announced New Zealand availability for this vehicle-to-grid or home-power technology.
Polestar and Danish energy company Clever are exploring whether electric cars can do more than simply draw power from the grid. Their new pilot project in Denmark will test Polestar 4 vehicles as rolling energy stores, able to support homes and potentially feed electricity back into the wider network.
The idea is known as V2X, or vehicle-to-everything. In practical terms, it means an EV battery could charge when electricity is cheaper or when the power mix is cleaner, then discharge later when prices rise or the grid is under heavier load. For households, that could mean lower energy costs. For electricity providers, it could offer another way to smooth demand.
The pilot will run in selected Danish homes and use the Polestar 4, the brand's electric SUV coupe. Polestar and Clever say the work will examine how bidirectional charging can help customers manage energy use while also supporting the electricity grid.
"A solution to some of our time's biggest energy challenges is potentially already sitting in your driveway," said Henrik Bang, managing director of Polestar Denmark.
That pitch matters because EVs are, by nature, large batteries that spend much of their time parked. If enough cars can charge and discharge intelligently, they could become part of a more flexible energy system rather than just another source of demand.
For now, this remains a Danish pilot rather than a confirmed customer rollout. Polestar has not disclosed any New Zealand availability for the programme, nor any local timing for V2X services tied to the Polestar 4.
Still, the trial points to a broader shift in how carmakers and energy companies view EVs. The next step may not simply be faster charging or longer range, but making the battery useful even when the car is sitting at home.
