EV Charger Error

Power Unit Fault (Kempower)

Updated March 2026

Share

This is general guidance based on the ChargeX MREC standard. Actual charger behavior varies by manufacturer and firmware version. Always follow on-screen instructions and contact the charging network if you are unsure.

Critical

The Kempower central power unit has a fault. Since Kempower systems share one power unit across multiple charging satellites, this fault may affect all connectors at the location.

What to do

  1. Try a different satellite. Some faults only affect specific power modules
  2. If no satellites work, the entire power unit is likely down
  3. Report the location to the network operator
  4. You will need to find an alternative charging location

Who's responsible?

  • This is likely a charger hardware issue
  • The charging network operator needs to fix this
