Polestar and charge point operator Clever announced a joint pilot program to test V2X technology in smart homes across Denmark starting this autumn.
The collaboration marks Denmark’s first complete vehicle-to-everything solution rollout.
V2X allows the Polestar 4’s battery to power homes during peak energy demand through vehicle-to-home functionality. The system can also send power back to Denmark’s electricity grid during high usage periods – helping stabilize the network through vehicle-to-grid capability.
The technology includes an “islanding mode” where the car serves as backup power during outages.
According to Clever, a fully charged EV can power an average home for several days, depending on energy consumption.
Testing Phase Details
The pilot program will focus on selected smart homes throughout Denmark. Polestar and Clever will evaluate how effectively the bidirectional charging works in real-world conditions.
Henrik Bang, managing director of Polestar Denmark, said the project puts consumers and their cars at the center of the green energy transition.
“In the future, the electric vehicle will not only transport people, but also energy. If electricity prices are high or the energy supply fails, the vehicle can become your power bank for the home or grid, reducing everyday energy costs and, in many cases, supporting increased use of renewable energy.”
The testing phase will provide data on how V2X integration affects both household energy costs and grid stability.
Commercial Rollout Timeline
Christina Fink, Clever’s CEO, described moving V2X from future vision to everyday reality.
“Denmark will be one of the first places where the electric car not only uses electricity but can also deliver it back to the home and the electricity grid when needed. This is the beginning of a new chapter, where the electric vehicle battery can both create value for the electric vehicle owner and strengthen the energy system.”
The Polestar 4 doesn’t currently support bidirectional charging as standard equipment. The automaker expects to enable V2X functionality through a future over-the-air software update.
Clever plans to launch its first commercial V2X solution by 2027.
The partnership represents a significant step toward integrating EVs into Denmark’s energy infrastructure – potentially reducing grid strain while providing financial benefits to EV owners through energy arbitrage opportunities.
