Polestar and Clever Trial Bi-Directional V2X in Denmark

Why It Matters

The 2027 commercial target gives the V2X market a concrete timeline, while software‑defined activation could let OEMs roll out the technology across existing fleets, accelerating grid‑flexibility solutions in Europe.

Key Takeaways

• First complete V2X pilot in Denmark tests three use cases.
• Clever’s platform will schedule both charging and discharge to optimize costs.
• Polestar 4’s V2X relies on over‑the‑air software updates.
• Commercial V2X services expected to launch in 2027 across Europe.

Pulse Analysis

Vehicle‑to‑everything (V2X) technology is emerging as a cornerstone of the energy transition, allowing electric cars to act as mobile batteries that can supply homes, feed the grid, or serve as emergency power. Denmark, with more than 50 % of electricity generated from wind and a sophisticated demand‑response market, provides an ideal testbed. The Polestar 4‑Clever pilot, slated to run until autumn 2026, puts three real‑world scenarios—vehicle‑to‑home, vehicle‑to‑grid and island‑ing—into daily operation, offering a rare glimpse of how EVs can smooth peak loads and bolster renewable integration.

The trial hinges on Polestar’s software‑defined vehicle architecture, which enables bi‑directional charging through over‑the‑air updates rather than hardware redesigns. Clever’s intelligent charging platform, already capable of shifting charging to the cheapest hours, will be extended to orchestrate discharge events, balancing household demand and grid signals. By leveraging existing communication standards and real‑time metering, the system can automatically decide when to export power or reserve energy for a blackout, demonstrating a scalable model that could be replicated across other OEMs and charging networks.

Commercial rollout is slated for 2027, a timeline that gives energy retailers, charger manufacturers and grid operators a concrete horizon for investment planning. If the pilot validates cost savings for drivers and measurable grid benefits, it could accelerate V2X adoption across Europe, turning EV fleets into distributed energy resources. Moreover, software‑first enablement means that older Polestar 4 units could be upgraded without new hardware, lowering barriers for fleet operators and expanding the addressable market for V2X services.
