Polestar has introduced its first commercial bi-directional charging solution for Polestar 3 owners in California through a partnership with dcbel. The vehicle-to-home (V2H) system enables energy discharge from the vehicle battery to power homes.
Highlights
- Initial V2H offer limited to Polestar 3 customers in California using dcbel’s Ara home energy system.
- Potential annual charging cost reduction of up to $1,300 with state rebates available.
- Vehicle can provide blackout backup power for up to 10 days.
- DC-based solution on the Polestar 3’s 400-volt architecture; broader features planned.
Program Details and Customer Benefits
The offering combines Polestar 3’s bi-directional capability with dcbel’s Ara DC home energy station. This setup allows the vehicle to discharge energy directly to the home, reducing reliance on grid power during peak periods.
California residents qualify for rebates through a California Energy Commission program managed by dcbel. These incentives offset a significant portion of the hardware and installation costs.
Reported benefits include:
- Charging cost savings: Up to $1,300 annually based on local rates and usage patterns.
- Backup power duration: Up to 10 days during outages, depending on household load and battery state of charge.
- Renewable energy integration: Prioritizes stored solar energy and minimizes grid draw.
More details and eligibility information are available at the dedicated site: https://polestar.dcbel.energy/.
Technical Implementation
The current solution uses direct-current (DC) bi-directional flow on the Polestar 3’s existing 400-volt platform. No hardware modifications to the vehicle are required.
Future expansions will include vehicle-to-grid (V2G) functionality and additional markets. In Europe, Polestar has already introduced a bi-directional-ready AC charger, Zaptec Go2, for Polestar 3 owners in Germany, with rollout to other countries planned.
Strategic Outlook
Polestar views bi-directional charging as a core element in lowering total cost of ownership and integrating electric vehicles into home energy management. The company continues software and hardware development to extend these capabilities across its lineup and additional regions.
