Polestar aims to transform electric vehicles into mobile power plants

Monday, January 22, 2024

In the Future Mobility-funded innovation project, Polestar, the Electric Power Research Institute, and the California Energy Commission are developing a roadmap towards the use of electric vehicles not only as loads but also as suppliers of electric power to the grid.

As the electrification of society progresses, there's a challenge: how do we handle the extra electricity demand? Enter V2G (vehicle-to-grid), a technology that turns electric cars into moving power sources.

Polestar, the Swedish electric performance car brand, is teaming up with the Electric Power Research Institute and the California Energy Commission, to work on an innovation project to assess the possibility of using electric cars to give energy back to the power grid. This collaboration seeks to pave the way for implementing V2G mobility services in Sweden and the USA. 

Imagine your electric car not just using electricity but also sharing its power with the grid when needed. That's what V2G aims to do by connecting EVs to the electricity grid and unlocking their storage capacity and surplus electricity. This project positions EVs as dynamic solutions to electricity demand, not mere contributors to the problem. For example, the average car is parked 90% of the time. That means a fleet can, beyond consuming electricity, actually contribute to the power grid’s stability, when the cars are not needed for transportation. 

This feasibility project is a crucial step to make V2G services a reality and is tailored specifically for the Swedish automotive industry and the dynamic state of California. By the project's end, a detailed implementation roadmap will guide future initiatives in this field.

The project’s team will also discuss future collaborations with a focus on the execution of the roadmap. The Polestar team will reach out to a wider audience about this project via channels such as the Swedish Electromobility Center. In addition, Polestar will share the insights from the project with other actors in Sweden and Europe, e.g., Vattenfall and Svenska kraftnät. Electric Power Research Institute and the California Energy Commission will also use their network to inform the US public about this project.

This project is made possible through funding and support from Future Mobility, a neutral innovation platform facilitated by Sweden's Innovation Agency, Vinnova, and Lindholmen Science Park. Future Mobility catalyzes research and innovation collaboration within sustainable mobility between the US and Sweden. With dedicated resources in both countries, the Future Mobility initiative aspires to lower the thresholds to collaboration and support the development of impactful, forward-thinking projects like this one.
