Polestar and Clever explore using EVs as a power bank for the home and the electricity grid in Denmark

• In a joint pilot project, Polestar and Clever demonstrate V2X technology in selected Danish homes using Polestar 4 vehicles
• V2X allows the electric vehicle to power homes or feed energy back to the grid, lowering energy costs for consumers
• A solution to some of our time's biggest energy challenges is potentially already sitting in your driveway, says Henrik Bang, Managing Director of Polestar Denmark

GOTHENBURG, SWEDEN - 28 May 2026. Polestar and the charging operator Clever are currently testing V2X (vehicle-to-everything) technology in selected Danish homes, enabling electric vehicles to supply homes with power from the vehicle's battery, send power back to the grid, and provide backup power during power outages.

In a joint technical pilot project, Polestar and Clever are now the first in Denmark to test a complete V2X solution, where Polestar 4 can not only charge, but also deliver power back to both the home and the grid*. This means the vehicle can function as a power bank and help reduce energy costs, stabilise the electricity grid and provide emergency backup power.

The pilot project

The pilot project aims to demonstrate solutions for using Polestar 4's battery for three central functions:

• Powering the home during peak energy demand (V2H)
• Supplying power to the electricity grid during peak demand (V2G)
• Providing backup power to the home in the event of a power outage (islanding mode)

Polestar cars are software-defined, meaning they improve and offer new functionality thanks to a continuous flow of over-the-air updates.

Henrik Bang, Managing Director of Polestar Denmark, says: "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. This is a huge opportunity that puts consumers and their cars at the centre of the green energy transition."

From future vision to everyday reality

As both the production and consumption of electricity increase, the technology can contribute to a more flexible and robust electricity grid while strengthening energy independence and supporting the transition to renewable energy.

In the pilot project, Clever builds on its intelligent charging platform, which already automatically schedules charging to when electricity is at its cheapest.

Christina Fink, CEO at Clever, says: "We are now taking V2X from a vision of the future 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. In 2027, the ambition is for Clever to launch the first commercial V2X solutions."

The goal is for the electric vehicle to be able to cover the household's electricity consumption during the most expensive hours of the day by storing cheap electricity and using it when prices peak.

The pilot project also explores how electric vehicles can function as emergency backup power during power outages, through islanding, where the home is supplied directly from the vehicle's battery. Depending on the household's consumption, a fully charged electric vehicle can keep an average home running for several days.
