The operation process of electric vehicle charger for first use

The use of electric vehicle chargers at low temperatures is as follows:

First, choose the right charging environment

Indoor charging priority:

In a low temperature environment, you should try to choose an indoor parking lot or a charging station with heating facilities for charging. This can effectively avoid battery and charger exposure to extremely cold weather, reduce battery cooling loss, improve charging efficiency.

Sheltered, sunny places:

If you must charge outdoors, you should try to choose a place that is sheltered from the wind and sunny. Sunlight can provide a certain amount of heat, helping to raise the temperature of the charging environment.

Second, preheat the battery and charger

Using the vehicle heating system:

In a low temperature environment, after starting the vehicle, its own heating system can be used to preheat the battery. When the battery temperature is close to its appropriate working range, then start the charging procedure. This preheating process can improve the battery charging efficiency and speed up charging.

Use a heat shield:

Put a heat shield on the battery and charger to help maintain the temperature of the battery and charger and reduce the impact of low temperatures on charging efficiency.

Third, choose the right charging method

Slow charge is preferred:

In low temperature environments, fast chargers may cause the battery to overheat, affecting battery life. Therefore, it is recommended to preferentially use a slow charger for charging. Although the slow charge takes a long time, the charging process is more stable, which is conducive to protecting the battery.

Avoid deep discharge:

In a low temperature environment, you should try to avoid letting the battery completely run out of power before recharging. Deep discharge can seriously damage the battery and shorten the battery life. It is recommended to charge the battery when the remaining power is 40%-50%.

Fourth, pay attention to charging details

Check the charging port:

Before charging, check the charging port for debris such as snow and ice to ensure that the charging port is dry and clean. If the charging port is covered with ice or blocked, it may cause charging failure.

Reduce car load:

When charging, the opening of electric equipment such as air conditioning and warm air in the car should be minimized to reduce the load of the battery. This helps to improve charging efficiency and shorten charging time.

Fifth, regular maintenance of batteries and chargers

Check the battery regularly:

In the low temperature environment, the battery system of the electric vehicle should be regularly checked, including checking whether the electrolyte of the battery is sufficient and whether the battery surface is clean. If the battery is faulty or abnormal, handle or replace the battery in time.

Maintenance charger:

Periodically check the charger cables and connectors for aging, damage, or corrosion. If the charger is found to be faulty or abnormal, it should be repaired or replaced in time.

Sixth, other precautions

Avoid charging on rainy or snowy days:

In rain and snow, try to avoid charging outdoors. If you must charge outdoors, you should do a good job of waterproof work, use umbrellas and other items for shelter protection.

Understand the status of charging facilities:

Before traveling in winter, you should understand the status of local charging facilities and choose a normal charging station for charging. Avoid charging inconvenience caused by charging facility failure.
