How electric vehicles can act as power sources when plugged into the grid

Polestar teams up with a number of partners to accelerate the shift towards more sustainable mobility.

According to a recent report by Boston Consulting Group, more than 90 % of all new cars sold in the Nordics in 2025 are expected to be either EVs or hybrids — and the last gasoline-powered vehicle is expected to go on sale in 2027. As more and more electric vehicles will naturally stress the world’s power grids, Polestar has joined forces with Chalmers University of Technology, energy grid supplier Göteborg Energi, charging solution provider CTEK, and energy solution provider Ferroamp, in a new energy project to accelerate the development of Vehicle-to-X (V2X) technology. V2X allows electric vehicles to act as power sources when they are plugged into the grid. After being charged, the vehicle can then supply its stored energy back to the grid, much like advanced off-grid power solutions that currently utilise battery packs with relatively small capacities to store energy for later use. An important step to accelerate the shift towards more sustainable mobility, according to Hans Pehrson, Polestar’s head of R&D. 

— EVs becoming part of the power grid ecosystem with bi-directional charging capabilities is absolutely crucial, he states. With this project, we take the first steps towards a V2X reality. We will now be able to develop the technology alongside our partners, with a view to integrating the technology in our future products. 

Part of the project will see the construction of two V2X demonstration charging stations in Gothenburg — one at the Polestar global headquarters and one on the Chalmers University campus.
