Polestar co-founds Swedish energy project to develop technology for electric cars supplying the grid and homes with electricity
New research into vehicle-to-grid and vehicle-to-home technology could maximise the storage of local green energy and provide back-up for peak periods
Polestar is part of a five-partner project in Sweden to accelerate the development of Vehicle-to-X (V2X) technology, including Vehicle-to-Grid (V2G) and Vehicle-to-Home (V2H). Supported by the Swedish Energy Agency, Polestar is joined by Chalmers University of Technology, the Gothenburg energy grid supplier Göteborg Energi, charging solution provider CTEK and energy solution provider Ferroamp, in the study which spans two years and nine months.
Hans Pehrson, Polestar’s head of research and development, said: “V2X will really revolutionise the future of power grids all over the world. I can imagine a world where thousands of electric vehicles, all plugged into the grid, act as an important part of a fully renewable energy system.
“For example, a V2H solution could maximise the storage of local green energy and provide back-up capacity for peak periods. This is a step towards a world without the need for coal or nuclear power plants.”
Part of the project will see the construction of two V2X demonstration charging stations in Gothenburg. One will be located at the Polestar global headquarters and the other at the Chalmers University campus.
V2X technology allows electric vehicles to act as power sources when they are plugged into the grid. Having ideally charged an electric vehicle with green energy, for example from wind or solar, the vehicle can then supply its stored energy back to the grid. This would be much like advanced off-grid power solutions that currently utilise battery packs with relatively small capacities to store energy for later use.
It’s great to see electric cars being used for other tasks beyond zero-emissions driving. This is something Nissan has also been championing in disaster zones. They have used electric cars to provide power when the electricity went down following a tsunami in Japan.
Hans Pehrson added: “This is exciting for us, we have been exploring this bidirectional technology for some time now and we want to bring it to life in our future products. It gives our R&D team great pleasure to be involved in this project with such fantastic future potential.”
