Polestar 4 pilot program enables electric vehicles to function as home power banks
Polestar, the Swedish electric vehicle manufacturer, has launched a pilot program allowing its Polestar 4 model to act as a mobile power source for homes, according to a company statement released on April 5, 2024. The initiative, developed in partnership with energy technology firm Enel X, enables the vehicle’s battery to supply electricity during outages or peak demand periods, according to a press release from Polestar.
How does the vehicle-to-home (V2H) feature work?
The Polestar 4’s V2H capability leverages its 78 kWh battery to deliver up to 3.6 kW of power to a home’s electrical system, according to Enel X. Owners can control the feature via the Polestar mobile app, scheduling energy discharge during specified times or triggering it manually during a power outage. The system integrates with smart meters to optimize energy use, as detailed in a technical overview from Enel X.
What does this mean for EV owners?
The pilot program, currently available in select markets including Sweden and the Netherlands, aims to address energy resilience and reduce reliance on grid power during peak hours, according to Polestar. Early participants report that the feature has lowered their electricity bills by up to 15% during summer months, per a survey conducted by the company. However, the system requires a dedicated home charging station and additional hardware, which may increase upfront costs.
How does Polestar’s approach compare to competitors?
Polestar’s V2H initiative joins similar efforts by other automakers. For example, Nissan’s Leaf-to-Home system, launched in 2021, offers comparable functionality but with a smaller battery capacity. Tesla’s Powerwall, while not vehicle-based, provides home energy storage with higher output. Enel X’s involvement highlights the growing collaboration between automakers and energy providers to expand EV utility beyond transportation, as noted in a 2023 report by the International Energy Agency (IEA).
What are the next steps for the pilot?
Polestar plans to expand the program to additional European markets by 2025, pending regulatory approvals. The company is also exploring partnerships with utility providers to offer dynamic pricing models that reward drivers for discharging energy during grid stress events, according to a spokesperson. A full commercial rollout is expected to follow after the pilot’s completion, though no timeline has been announced.
As the automotive and energy sectors converge, vehicle-to-home technologies like Polestar’s could play a critical role in shaping sustainable energy systems. The success of this pilot may influence broader adoption of EVs as decentralized power sources, aligning with global efforts to decarbonize both transportation and electricity sectors.
