Missing Phase

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.

Warning

One of the three electrical phases supplying the charger is missing. This is a site-level wiring or grid issue. The charger cannot deliver full power.

What to do

  1. Charging may work at reduced speed if the charger can operate on fewer phases
  2. If charging does not start at all, move to a different charger
  3. Report to the charging network. This is an electrical supply issue
  4. Check if other chargers at the same site are also affected

Who's responsible?

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