Charging is very slow compared to charger rating; vehicle reports reduced charging power but no charger error code.

Safety first: Most checks can be done without opening the charger.

• Check user settings: In the Polestar app or charger menu, verify the maximum current setting. Increase it within the limits of your electrical installation if safe.
• Verify supply rating: Confirm the breaker and wiring size for the charger. The charger may automatically limit current to protect an undersized circuit.
• Improve cooling: Ensure the charger is not exposed to direct sunlight or enclosed in a tight cabinet. Improve airflow around the unit.
• Check load management: If connected to a home energy manager or multiple chargers, verify that load balancing settings are not intentionally limiting current.
