Possible Causes

Failed internal pre‑charge or safety relay, Control board relay driver failure, Welded relay contacts from previous fault, Incorrect feedback wiring to control board

How to Fix / Troubleshooting

Safety first: This involves internal high‑voltage components. Turn OFF the breaker and do not attempt to bypass safety relays.

  • Power reset: Turn OFF the breaker for 5 minutes, then ON. Attempt to start a charge. If E07 reappears immediately, leave the unit off.
  • Listen for relay clicks: During startup, you may hear one or more faint clicks. No clicks or rapid chattering can indicate a relay or driver issue.
  • Check for prior events: If E07 started after a known power surge, lightning event, or breaker trip, internal relays may have been damaged.

Because relay self‑test is a critical safety function, the EVgo charger should be serviced by an authorized technician. They will test the internal safety relays and replace the relay module or main control board as required.
