Handling of leakage signs during the use of electric vehicle chargers

When there are signs of leakage in the electric vehicle charger during use, the following measures should be taken for handling:

First, stop charging immediately

Once you notice any signs of leakage from the charger, such as a tingling sensation when touching the charger's casing, sparks or an unpleasant smell around the charger, you should immediately stop charging and disconnect the charger from the power source and the vehicle.

Second, check the charger and the vehicle

Check the charger:

Carefully observe the casing of the charger to see if there are any cracks, damages or charred marks.

Check whether the power cord, plug and interface of the charger are in good condition, and whether there is any damage, looseness or deformation.

Use a multimeter or other tools to check whether the output voltage and current of the charger are normal, and whether there is any unstable output voltage or abnormal current.

Inspect the vehicle:

Confirm whether the vehicle charging interface is clean and free of foreign objects, and whether the interface connection is firm.

Check if there are any abnormalities in the vehicle's battery and electrical system, such as whether the battery casing is damaged or if the electrical circuits are aged or exposed.

Third, take emergency measures

Stay away from the leakage area: After confirming that the charger is leaking electricity, quickly move away from the leakage area to avoid the risk of electric shock.

Cut off the power supply: If possible, cut off the power supply of the circuit where the charger is located to prevent the leakage accident from expanding.

Notify professionals: Contact the after-sales service personnel of the electric vehicle or professional maintenance personnel, explain the situation and request on-site inspection and handling.

Fourth, follow-up handling

Repair or replace the charger: If the charger is faulty or damaged, it should be repaired or replaced in a timely manner to ensure that the charger can work normally and safely and reliably.

Inspect the vehicle's electrical system: After repairing or replacing the charger, it is recommended to conduct a comprehensive inspection of the vehicle's electrical system to ensure there are no other damages or malfunctions caused by leakage.

Strengthen safety awareness: Enhance safety awareness, understand the correct usage methods of electric vehicle chargers, and avoid using chargers in harsh environments such as dampness and high temperatures to reduce the occurrence of electric leakage and other safety accidents.

Fifth, preventive measures

When purchasing an electric vehicle charger, one should choose a product from a reputable brand with reliable quality and avoid using inferior or "three-no" products.

Regular inspection and maintenance: Regularly inspect and maintain the charger and vehicle to promptly identify and address potential safety hazards.

Follow the usage instructions: Operate strictly in accordance with the charger's usage instructions to avoid safety accidents caused by improper use.

Sixth, Precautions

Do not disassemble the charger by yourself: Non-professionals should not attempt to disassemble the charger for repair by themselves to avoid causing greater damage or safety hazards.

Avoid touching the charger during charging: During the charging process, try to avoid touching the charger and the vehicle's charging interface to reduce the risk of electric shock.

Keep the charging environment well-ventilated and dry: Ensure that the charging environment is well-ventilated and dry, and avoid using the charger in damp, high-temperature or flammable and explosive environments.

In conclusion, when there are signs of leakage in an electric vehicle charger, charging should be stopped immediately and emergency measures taken. At the same time, professional personnel should be contacted for inspection and handling. By enhancing the awareness of safe usage and taking preventive measures, the risk of safety accidents such as electric leakage can be reduced.
