Possible Causes
Loose input connections causing voltage dips, Overheating of connector or cable, Vehicle-side charging control interruptions, Marginal Wi-Fi causing remote stop commands or firmware instability
How to Fix / Troubleshooting
Safety first: Do not continue using the charger if the connector or cable feels excessively hot.
- Check for heat: After a few minutes of charging, carefully touch the J1772 handle and cable. Warm is normal; very hot or soft plastic is not. If overheated, stop using and plan to replace the cable/handle assembly.
- Observe vehicle messages: Check the vehicle’s dashboard or app for any charging-related warnings or timers that might be stopping the session.
- Inspect wiring: Have an electrician verify that all input lugs in the panel and charger are tight and that wire gauge is appropriate.
- Disable smart features temporarily: If possible, disable scheduled charging or remote control features in the FLO app to rule out software stops.
- If dropouts persist with multiple vehicles: A technician should test the main control board, current sensor, and temperature sensors for intermittent faults.
