Possible Causes

Loose connection at breaker or charger terminals, Overheating of connector or cable, Unstable Wi‑Fi causing remote stop commands, Vehicle‑side charging interruptions

How to Fix / Troubleshooting

Safety first: Turn OFF the breaker before tightening any electrical connections. Do not touch hot or discolored components.

  • Monitor temperature: During a charge, periodically feel (carefully) the EVgo connector and cable. If they become excessively hot, stop using the charger and have it inspected.
  • Check wiring tightness: With power OFF, verify that all line and ground lugs in the charger and at the breaker are tight to the specified torque.
  • Disable smart features temporarily: Turn off any load management, demand response, or scheduled stop features in the EVgo app to rule out software‑initiated stops.
  • Test with another vehicle: If dropouts only occur with one EV, the issue may be with that vehicle’s onboard charger.

Persistent unexplained dropouts warrant a visit from an EVgo‑authorized technician to check for thermal issues, contactor performance, and control board logs.
