Electric vehicle chargers are frequently charged and maintained in logistics parks

In logistics parks, the maintenance of frequent charging of electric vehicle chargers needs to start from aspects such as equipment inspection, charging management, fault handling, environmental adaptation and personnel training. The following is a specific explanation:

Establish an equipment inspection system: Electric vehicles in the logistics park charge frequently. A daily inspection plan should be formulated at least once to check the appearance of the equipment, connection status, cable integrity, interface cleanliness, whether the display screen is normal, and alarm indications, etc. After the inspection, fill in the records and form electronic files to facilitate the traceability of problems.

Optimize the charging management strategy

Shallow charging and shallow discharging: It is recommended that electric vehicles in logistics parks be charged daily to keep the batteries in a shallow cycle state and extend their lifespan.

Set the charging duration reasonably: Set the charging duration reasonably based on the vehicle's condition and remaining battery power to avoid overcharging.

Avoid frequent fast charging: During fast charging, the current is relatively large, which will cause the battery temperature to rise rapidly. Long-term frequent fast charging can damage the battery. It is recommended to avoid using fast charging as much as possible when there is sufficient time, or to arrange the charging time reasonably.

Improve the fault handling mechanism:

Fault classification and response: Establish a fault classification and response process. When a fault occurs, cut off the power supply immediately and notify maintenance personnel for on-site inspection and repair.

Spare parts reserve: Establish a spare parts warehouse for vulnerable parts of charging equipment, such as fuses, connecting wires, interface accessories, etc., to ensure rapid and efficient fault repair.

Emergency communication: Establish an emergency communication mechanism, including multi-channel contact groups such as phone calls, wechat, and text messages, to ensure timely information transmission.

Strengthen environmental adaptability maintenance:

Heat dissipation system maintenance: Logistics parks may face heavy dust environments, and the heat dissipation systems of charging piles are vulnerable to threats. During daily inspections, carefully clean the accumulated dust on the surface of the radiator to prevent it from clogging the heat dissipation fins and affecting the heat dissipation efficiency.

High-altitude adaptability: If the logistics park is located in a high-altitude area, due to the thin air, the electrical insulation performance will change. It is necessary to increase the detection frequency of the insulation performance of electrical components and reasonably optimize the heat dissipation system, such as appropriately increasing the power of the cooling fan.

Emphasize personnel training and responsibility allocation:

Systematic training: All maintenance and emergency response personnel should receive systematic training to master equipment maintenance skills and emergency response procedures. The training content includes equipment operation procedures, fault diagnosis, fire safety, first aid skills, emergency plan drills, etc.

Responsibility allocation: Develop a list of job responsibilities, clearly defining the responsibilities of the equipment maintenance person in charge, emergency response person in charge, on-site safety officer, and other positions. Establish an assessment system and incorporate maintenance quality and emergency response effectiveness into performance evaluation.
