Maintain the stability of the charging speed of electric vehicle chargers

To maintain the stability of the charging speed of electric vehicle chargers, the following aspects can be considered:

First, the charging equipment should be compatible with the vehicle

Select the appropriate charging equipment: Understand the charging methods supported by the vehicle (such as AC slow charging, DC fast charging) and power, and choose a matching charging pile. If the charging pile does not match the vehicle battery pack, it will cause unstable charging current. It is necessary to replace the charging pile with a suitable one or inspect the vehicle battery pack.

Use original or compatible devices: Avoid using non-standard chargers to prevent damage to the battery, which may lead to unstable charging or excessive load.

Second, charging operation norms

Correct insertion and removal of the charging gun: When inserting or removing the charging gun, apply force vertically and avoid tilting or violent insertion and removal to prevent the plug from loosening, oxidation of the contact surface causing heating, short circuit or poor contact.

Control the charging time: Arrange the charging time reasonably according to the battery capacity and remaining power to avoid overcharging. New energy vehicles usually need 7 to 8 hours to be fully charged. Overcharging can cause severe wear and tear on the battery.

Third, battery status management

Avoid deep discharge: New energy vehicles usually remind people to charge as soon as possible when the battery level remains at 20% to 30%. Do not charge when it drops below 20% to prevent deep discharge and shorten the battery life.

Regular battery balancing: There may be performance differences among the individual battery cells in the battery pack of new energy vehicles. It is necessary to carry out regular battery balancing treatment to eliminate the differences between batteries and improve overall performance.

Battery status check: Regularly inspect and maintain the battery to ensure the normal operation of the battery management system (BMS), and replace aged batteries in a timely manner. Battery aging can affect the stability of the charging current.

Fourth, environmental factor control

Avoid charging at extreme temperatures:

Low-temperature environment: In winter, when the temperature is low, the performance of batteries will decline significantly, resulting in low charging and discharging efficiency, reduced battery capacity, and decreased driving range. The car can be parked indoors or in a warm place for charging. Some vehicles will heat the battery to a certain temperature before charging.

High-temperature environment: During the hot summer, the battery's protection mechanism will reduce the charging speed to prevent overheating. Charging should be avoided in direct sunlight.

Keep the charging environment dry: The charging plug should be kept clean and dry. Especially in winter, prevent the rain and snow meltwater on the plug from flowing into the vehicle body. Try to avoid charging the vehicle outdoors on rainy days to prevent rainwater from entering the charging device and interface.

Fifth, power supply and circuit inspection

Check power supply stability: Regularly inspect the power lines and output stability of the charging station to ensure that the power supply meets the standards. Unstable grid voltage may cause current fluctuations. It is necessary to check whether the protection function of the power adapter is normal. If necessary, use a voltage protector for adjustment.

Check for aging lines: Unstable power output at the charging station or aging power lines can cause fluctuations in the charging current. It is necessary to replace the aging lines in a timely manner.

Sixth, maintenance of charging equipment

Regular maintenance of charging piles: Regular maintenance and inspection of charging piles should be carried out, and damaged electronic components such as current sensors or control module failures should be replaced in a timely manner to ensure the normal operation of charging equipment.

Check the matching of charging protocols: If the communication protocols between electric vehicles and charging devices do not match, it may cause current fluctuations. If the agreement does not match, consult the manufacturer or a professional to adjust the charging Settings to meet the vehicle's needs.
