What to Do If Leakage Current Is Detected on Your EV Charger ？

Safety is the top priority when charging an electric vehicle. Modern EV chargers are equipped with multiple protection mechanisms, including leakage current detection. If your charger detects a leakage current, it means the device has identified an abnormal flow of electricity that could pose a safety risk.

Understanding how to respond when this happens is essential for protecting yourself, your vehicle, and your property. Below is a simple, step-by-step guide on what to do if your EV charger reports a leakage current.

Step 1: Immediately Stop Charging and Disconnect the Charging Connector

As soon as you see a leakage current warning or the charger automatically stops due to a leakage fault, do not ignore it. Immediately stop the charging session if it is still active and carefully disconnect the charging connector from your vehicle.

Do not touch any exposed metal parts or wet surfaces while disconnecting. If the connector or cable appears damaged, hot, or wet, avoid direct contact and turn off the power supply to the charger from the circuit breaker first if possible.

Step 2: Wait a Brief Interval, Then Reconnect and Retry

After disconnecting the connector, wait for a short period of time — typically a few minutes. This allows the system to reset and any temporary moisture or minor electrical fluctuation to clear.

Once the interval has passed, reconnect the charging connector to your vehicle and restart the charging session. Observe the charger’s status indicator to see if it begins charging normally or if the leakage current warning appears again.

Important: If the charger automatically stops and shows the same warning again, do not keep retrying. Repeated attempts could worsen a potential safety issue.

Step 3: Contact Customer Service for Resolution

If the leakage current issue persists after a retry, stop using the charger and contact customer service for professional assistance.

When you reach out, provide the following details to help the support team diagnose the problem quickly:

• Charger model and serial number
• A description of the fault (including when it first occurred)
• The status shown on the charger display or indicator lights
• Whether the charging cable or connector has any visible damage or moisture
• Any recent weather conditions (heavy rain, flooding, etc.) if the charger is installed outdoors

Customer service can guide you through further troubleshooting or arrange for a qualified technician to inspect the unit.

Why Leakage Current Protection Matters

Leakage current detection is a critical safety feature in EV chargers. It helps prevent electric shock and reduces the risk of fire caused by insulation failure, water ingress, or damaged cables. When this protection is triggered, it is a sign that the charger is doing its job — but it also means the underlying cause must be addressed before charging can resume safely.

Final Safety Tips

• Always have your EV charger installed by a qualified electrician.
• Regularly inspect the charging cable, plug, and connector for signs of wear, cracks, or moisture.
• If your charger is installed outdoors, make sure it has adequate weather protection.
• Never bypass or disable safety features, including leakage current detection.
