Polestar showcased innovation and a strong path forward at its inaugural Polestar Day. Held in Los Angeles, California, the event gathered key executives and innovations in front of an audience of customers, investors and press.
Thomas Ingenlath, Polestar CEO, says: “Polestar Day provides substantial insight into our products and the innovations we are working on together with global leaders in various fields to bring the best electric performance cars to market. We are progressing from having one car on the roads – Polestar 2 – to having three, with the ongoing launches of our two SUVs, Polestar 3 and Polestar 4. The coming months will be some of the most exciting our young company has ever seen.”
Polestar was joined at the event by executives from strategic partners including Bcomp, Göteborg Energi, Luminar, Mobileye and StoreDot.
Polestar’s full range of future models was exhibited together for the first time, including Polestar 3, Polestar 4, Polestar 5, Polestar Precept, the Polestar Electric Roadster Concept and Polestar Synergy. Guests were able to test drive the latest MY24 Polestar 2, as well as ride in Polestar 3 and Polestar 4 development prototypes with Polestar engineers and experts.
Polestar initiates V2G projects and develops Virtual Power Plant to support large-scale energy transition
Polestar is joining stakeholders in the electricity grid sector with a large-scale vehicle-to-grid (V2G) project in Gothenburg, Sweden, funded by the Swedish Innovation Agency Vinnova and piloting a large fleet of Polestar 3 cars.
Together with Swedish National Grid authority Svenska Kraftnät, local grid owner Göteborg Energi Nät, regional energy distributor Vattenfall Eldistribution, home charging provider Easee, and research partner Chalmers University of Technology, Polestar aims to find potential business models for V2G and trial tangible use cases that can be scalable and applicable across regions.
At the same time, Polestar is forming a collaboration with the California Energy Commission and the independent, non-profit energy R&D institute EPRI, on a pre-study – also funded by Vinnova – to create a roadmap for the implementation of vehicle-to-grid services in California.
Bidirectional charging technology allows Polestar 3 cars to not only charge but also discharge energy from their batteries back to the individual home or the electricity grid. To help manage V2G integration, Polestar is developing a Virtual Power Plant (VPP) that links all participating Polestar 3 cars connected to the grid. The cloud-based VPP calculates the collective capacity of connected batteries and initiates charging or discharging based on grid demand and battery longevity optimisation. This will allow car owners to both contribute to the energy transition and monetise their EV while it’s parked, without any intervention.
The owner simply plugs in their vehicle and the VPP and smart charging tech will do the rest – optimising battery use for their transport needs and support the grid.
EV batteries have the potential to be useful on a large scale. With V2G solutions, EVs have the potential to become an important flexible energy resource and support electricity grids, beyond already being a means for more sustainable transportation.
“Vehicle-to-grid has the potential to not only benefit individual customers, but whole communities. The average car is parked 90% of the time. With the bi-directional charging capabilities of Polestar 3 and the Polestar VPP, we can explore business models and community solutions that can unlock the true potential of V2G and enable owners to support the energy transition when they don’t need their car for driving,” says Thomas Ingenlath, Polestar CEO.
Accelerated electrification of mobility, and industry paired with an expansion of renewable electricity, puts higher demands on the available capacity in electricity grids. Production from variable energy sources, such as wind and solar, is dependent on weather and cannot easily be planned and matched to demand. To avoid extensive and costly investments in grid expansion and reinforcement, there is a need for flexible energy storage to help balance supply and demand.
As EV adoption continues to grow, EV batteries will become a useful existing storage solution for both national, regional, and local grids.
“Vehicle to Grid will have an impact on the electrical grid and how our customers can actively participate and contribute to increased stability in the grid. The car will become a natural element and a potential resource for this. V2G will also influence how electricity grid companies plan their grids in the future,” says Peter Söderström, Manager of Innovation & Market Outlook at Vattenfall Eldistribution.
“V2G technologies turn EVs into virtual power plants, making homes and the grid more resilient while putting money into the pockets of drivers. The CEC is excited to have Polestar partner with innovators in California to advance their V2G plans,” says Commissioner Patty Monahan of the California Energy Commission.
The Gothenburg pilot project’s test phase is planned to commence in Gothenburg during the first half of 2024 and run for two years. The pilot will include a large fleet of Polestar 3 cars, aiming to become one of Europe’s largest V2G pilots, featuring essential representatives from national and local energy infrastructure.
The California pre-study begins in December 2023 and runs until October 2024.
