About 48V-96V vehicle charger routine maintenance

China [CN]

Description：As an important part of electric vehicles, the maintenance and care of electric vehicle chargers are crucial to ensure charging efficiency and extend service life. The following are detailed steps and precautions for daily maintenance of 48V/96V on-board chargers:

First, check and maintain the connected circuits, including:

Voltage detection: Use a multimeter to regularly detect the input and output voltages of the charger to ensure that they are within the specified range.

Electronic component inspection: Check whether the rectifier, filter capacitor, switch tube, etc. are working properly, and replace or repair faulty parts in time.

Battery status monitoring

Battery voltage and internal resistance: Measure the battery voltage and internal resistance to determine whether there is a short circuit or undercharging.

Connection wire inspection: Ensure that the connection wire is secure, not loose or corroded, and replace it if necessary.

Second, the appearance and structure of the overall equipment

Shell inspection: Regularly check whether the charger shell is deformed or damaged, and replace it if necessary.

Connection harness maintenance: Check whether each connection harness is damaged or cracked to ensure that the high and low voltage connections are firm.

Third, check the heat dissipation fan and cooling system

Fan operation: Check whether the fan rotates flexibly and clean the outer surface.

Cooling line: Check the cooling line connection for leaks.

In summary, put safety first: Before any repair or inspection, make sure the charger is powered off to avoid the risk of electric shock.

Professional support: If you encounter complex technical problems or are unsure how to make a repair, you should seek help from professional technicians.

Regular maintenance: Even if there are no obvious signs of failure, regular maintenance checks should be performed to prevent potential problems.

In general, following the detailed maintenance steps and precautions above can effectively protect the performance of the 48V/96V on-board charger and extend its service life. Regular maintenance can not only reduce the occurrence of unexpected failures, but also ensure the safety and charging efficiency of electric vehicles.
