Splitvolt EV charger displays E20 and charging is disabled; may occur when the charger detects an incompatible or unsupported vehicle.

Safety first: Do not attempt to modify the vehicle inlet or charger connector.

• Test with another EV: If another vehicle charges normally, the issue is likely with the original EV’s onboard charger or communication.
• Check vehicle software: Ensure the EV has the latest software/firmware from the manufacturer.
• Update charger firmware: Install the latest Splitvolt firmware to improve compatibility with newer vehicles.
• Try a different EVSE: If the vehicle charges fine on other stations but not on the Splitvolt, contact Splitvolt with vehicle details for compatibility support.
