Maintenance measures for electric vehicle chargers in humid environments

Maintenance measures for electric vehicle chargers in wet environments are crucial, and the following are some key maintenance measures:

First, preventive measures

Choose the right charging environment:

Try to avoid charging in the outdoor or unshielded charging pile, should be preferred to choose a sunshade device or a roof charging pile.

A waterproof cover can be used to protect the charger when charging at home.

Check charging devices and connectors:

Before charging, check that the charging gun and charging port are intact to ensure that there is no water or moisture.

Use waterproof charging cables and connectors, and ensure that the connection is tight and not loose.

Keep your hands dry:

Keep your hands dry while charging and avoid direct contact with metal parts to prevent accidental electric shock.

Second, emergency treatment measures

Disconnect power immediately:

Once the charger is found to be wet or in a humid environment, the charging process should be stopped immediately and the connection should be disconnected from the power supply to prevent electrical short circuit or the risk of electric shock.

Check the charger condition:

Carefully inspect the charger's appearance for cracks, breakage, or other physical damage.

Check whether there is water inside the charger, and if necessary, disassemble the charging gun head for internal inspection (this operation is recommended by professionals).

Drying treatment:

Use a clean cloth or paper towel to blot the surface of the charger.

Place the charger in a ventilated and dry environment to dry naturally, avoid using heating equipment such as hair dryers, so as not to cause damage to the internal components.

Third, regular inspection and maintenance

Check the waterproof performance of the charger:

Regularly check whether the waterproof seal of the charger is intact, and replace it in time if it is damaged.

For chargers with a waterproof design (such as IP65 or higher), although they can theoretically withstand a certain degree of rain, they should also avoid prolonged exposure to rain.

Check cables and connectors:

Periodically check the charger cables and connectors for aging, damage, or corrosion.

If the cable skin becomes hard, discolored, or cracks increase, replace the cable in time.

Keep the charger clean:

Use a dry cloth or paper towel regularly to wipe dust and dirt from the surface of the charger.

Avoid wiping the charger with wet rags or water to avoid damaging its waterproof performance.

Fourth, professional maintenance and replacement

Seek professional help:

If you find that the charger fails or the performance deteriorates in a humid environment, you should immediately stop using it and seek professional maintenance services.

Do not disassemble or repair the charger yourself, so as not to cause greater damage or safety hazards.

Timely replacement of aging parts:

For aging or damaged charger parts (such as cables, plugs, etc.), should be replaced in time to ensure the safe and reliable use of the charger.

Fifth, other precautions

Monitoring during charging:

During the charging process, try not to leave the vehicle in order to respond to any potential problems.

If you find that there are abnormal phenomena during the charging process (such as abnormal noise, heat, etc.), you should immediately stop charging and seek professional help.

Preparation before the rainy season:

Before the rainy season, carry out a comprehensive inspection and maintenance work on the charger.

Ensure that the charger is waterproof and in good overall condition to meet the challenges of wet environments.
