Key points for maintaining electric vehicle chargers at different altitudes

The key points for maintaining electric vehicle chargers at different altitudes are as follows:

First, low-altitude areas (below 2,000 meters)

Regular maintenance:

Maintain ventilation: Ensure that the charger is well-ventilated to prevent the plug from overheating and to avoid affecting the charger's lifespan and charging status due to excessive heat.

Regular inspection: Regularly inspect the appearance of the charger, connectors, insulation performance, voltage and communication status, etc., to ensure the charger is working properly.

Proper charging: Master the charging time well. Generally, the charging time is about 10 hours. Avoid overcharging and overdischarging to extend the battery life.

Usage Specification:

Dedicated charger: Use a dedicated charger and do not replace it at will to avoid abnormal charging caused by mismatched parameters.

Avoid high current discharge: When starting, carrying passengers, or going uphill, avoid high current discharge to reduce damage to the battery.

Second, high-altitude areas (above 2,000 meters)

Electrical clearance and insulation performance:

Electrical clearance requirements: At altitudes above 2,000 meters and below 5,000 meters, the electrical clearance between the primary and secondary sides of the charger should be greater than 6mm to meet the safety requirements in high-altitude areas.

Insulation performance inspection: Regularly check the insulation performance of the charger to ensure that in high-altitude areas, the insulation strength will not decline due to the decrease in air density, which may cause leakage accidents.

Heat dissipation and temperature rise control

Cooling fan adjustment: In high-altitude areas, the air density is low, and the air flow of the cooling fan decreases. It is necessary to appropriately adjust the air intake volume of the cooling fan, such as increasing the fan speed or replacing it with a model of higher power.

Real-time temperature rise monitoring: By detecting the temperature rise in real time to adjust the air intake volume, the charger can dissipate heat normally in high-altitude areas and avoid malfunctions caused by overheating.

Equipment compatibility and stability:

Plug compatibility: In high-altitude areas, there may be situations where the charging pile is incompatible with the vehicle plug. It is necessary to prepare a conversion plug in advance to ensure smooth charging.

Avoid car charging: In high-altitude areas, the 12V interface voltage of the car is unstable, and the cigarette lighter interface is prone to loosening. Long-term charging may cause the device to overheat and increase the risk of failure. It is recommended to choose to charge with the mains power as much as possible.

Anti-jolting and anti-impact

Vibration prevention measures: Road conditions in high-altitude areas may be poor. It is necessary to take good vibration prevention measures for the charger to avoid damage to the equipment due to jolting and impact during movement.

Environmental adaptability

Temperature adaptability: In high-altitude areas, the temperature difference between day and night is large. It is necessary to ensure that the charger can adapt to significant temperature changes to avoid a decline in equipment performance due to temperature variations.

Ultraviolet protection: In high-altitude areas, ultraviolet radiation is strong. It is necessary to pay attention to the protection of the plastic parts and rubber sealing parts of the charger to avoid material aging caused by ultraviolet radiation.
