The 2020 Honda Clarity Plug-In Hybrid offers approximately 47 miles of electric range when fully charged. When charging is repeatedly interrupted, you lose the electric-only capability that makes the Clarity PHEV fuel-efficient. Here's how to troubleshoot charging interruptions.
How Clarity Charging Works
The Clarity PHEV uses a 17-kWh battery pack that charges through the driver's side charging port. Standard Level 1 charging uses a household 120V outlet. Level 2 charging at 240V provides faster charging. The vehicle's onboard charger converts AC power to DC for battery storage.
Common Causes of Charging Interruption
EVSE (charging equipment) faults are frequently responsible. The portable charging cord that comes with the vehicle has built-in safety circuits that can trip from power fluctuations. Third-party Level 2 chargers can also fault for various reasons.
Electrical circuit issues at your home can cause interruptions. GFCI outlets may trip from current leakage. Circuits shared with other appliances may overload. Voltage fluctuations from poor wiring cause the charger's safety circuits to activate.
Vehicle-side issues include faulty charge port latching, onboard charger faults, or battery temperature management problems. The system won't charge if the battery is too hot or too cold.
Troubleshooting Steps
Try different outlets if using Level 1 charging. Avoid extension cords and shared circuits. Ensure the outlet is dedicated and properly grounded. Test with a known-good outlet to rule out home electrical issues.
Inspect the charging port for debris, damage, or moisture. The port must latch securely for charging to proceed. Clean any visible contamination with a dry cloth.
Reset the vehicle's charging system by pressing and holding the start button for 30 seconds without your foot on the brake. This resets various modules that may have faulted.
When Professional Help Is Needed
If charging interruptions persist after basic troubleshooting, dealer diagnosis can identify whether the issue is with the onboard charger, battery management system, or other components. Bring your EVSE equipment to the appointment so they can test it as well.
