Maintenance details of electric vehicle chargers in outdoor environments

In outdoor environments, the maintenance of electric vehicle chargers needs to focus on aspects such as waterproofing, dustproofing, sun protection, lightning protection, and temperature control. The following are the specific details:

Waterproof and moisture-proof measures

Choose a shelter from the rain: Prioritize charging indoors or in a sheltered parking lot to prevent the charger from being directly exposed to the rain. If it is necessary to charge the vehicle outdoors, choose a location with higher ground and no standing water to prevent the bottom components of the vehicle from being soaked by water.

Interface protection: Before charging, carefully clear the accumulated water from the charging port and the charging gun, and wipe them with a dry and clean cloth to ensure that the connection points are dry and clean. During the charging process, a rain cover or plastic sheet can be used to cover the connection part between the charging pile and the vehicle to prevent rainwater from directly falling onto the equipment.

Cable protection: Wrap the charging cable with plastic bags or other items to prevent damage caused by prolonged exposure to rain. After charging is completed, promptly return the charging gun tip to its original position to prevent rainwater from splashing into it.

Dust prevention measures

Regular cleaning: Regularly remove dust and debris from the surface of the charger. You can use a soft-bristled brush or a dry cloth to gently wipe it.

Check the sealing performance: Regularly inspect the sealing components of the charger, such as sealing strips and interface covers, to ensure they are intact and prevent dust from entering the interior.

Sun protection measures

Avoid direct sunlight: Prolonged exposure to sunlight can cause the charger's casing to age and discolor, and even affect the performance of the internal components. Therefore, the charger should be placed in a cool area as much as possible or covered with sunshades or other equipment.

Pay attention to temperature control: High-temperature environments will accelerate the aging of the internal components of the charger and reduce its service life. In hot weather, it is advisable to avoid charging for a long time under direct sunlight. It is better to charge in the early morning or evening when the temperature is lower.

Lightning strike protection measures

Avoid charging during thunderstorms: During thunderstorms, lightning may cause unpredictable damage to vehicles and charging equipment, so charging outdoors should be avoided.

Install lightning protection equipment: If you often need to charge outdoors, you can consider installing lightning protection equipment such as lightning rods and surge protectors to reduce the risk of lightning strikes.

Temperature control

Monitor temperature: Regularly check the operating temperature of the charger to ensure it is within the normal range. Generally speaking, the operating temperature of a charger should be between -20℃ and 40℃.

Heat dissipation treatment: If the charger operates in a high-temperature environment, it should be ensured that it has good heat dissipation. It can clean the dust and debris on the heat sink to ensure smooth ventilation. Auxiliary devices such as cooling fans can also be used for heat dissipation.

Regular inspection and maintenance

Visual inspection: Regularly check the appearance of the charger for any damage, deformation or other conditions. If any problems are found, replace it in a timely manner.

Electrical performance testing: Regularly use professional equipment to test the electrical performance of the charger, such as whether the output voltage and current are stable, and whether the insulation resistance meets the requirements, etc.

Software update: Update the charger's software in a timely manner to fix known vulnerabilities and enhance performance and compatibility.
