EVgo Reduced Output Current / Derating

Vehicle reports that charging current is lower than expected; EVgo charger appears limited

Advertisements

Possible Causes

Charger configured to lower current in settings, Thermal derating due to high temperature, Load management or demand response active, Faulty current sensor in EVgo charger

How to Fix / Troubleshooting

Safety first: No high‑voltage work is required for configuration checks.

  • Check settings: In the EVgo app or installer menu, verify the maximum current setting and adjust if safe and allowed by the circuit.
  • Temperature check: If the charger is hot, allow it to cool and improve ventilation. Thermal derating will reduce current to protect components.
  • Disable load management: Temporarily turn off any smart load sharing or demand response features to see if current increases.

If output remains low despite correct settings and normal temperature, the EVgo current sensor or control board may be faulty and require service.
