How to properly maintain the power battery system of new energy vehicles?

Gently press the accelerator pedal
When starting, new energy truck drivers must pay attention to gently press the accelerator pedal. If a new energy truck accelerates violently when starting, it will cause a large current discharge of the battery, thereby damaging the physical properties of the battery plate and affecting the battery life.
Avoid exposure to the sun and freezing
When parking new energy truck drivers, you need to pay attention to the surrounding environment. If a new energy truck is exposed to the sun for a long time or parked in an environment with too high a temperature, it will cause the internal pressure of the battery to increase and the battery to lose water, causing the battery activity to decrease. Similarly, if it is parked in a cold environment for a long time, it will also affect the battery’s endurance and have an adverse effect on the performance of the battery pack.
Over-discharge is not feasible
New energy trucks should avoid frequent over-discharge and under-charging, which will shorten the battery life. During use, truck drivers should determine the charging time and efficiency according to the actual vehicle conditions. If the power meter indicator light is on, charge as soon as possible, otherwise excessive discharge of the battery will affect the life, insufficient charging will occur, and the SOC will be falsely high.
Ventilate before turning on the air conditioner
The weather is hot in summer, and truck drivers often turn on the air conditioner immediately after getting in the car. However, turning on the cooling system directly in the closed cab after being exposed to the sun will put the battery under double high temperature pressure, which will not only consume power faster, but also affect the battery life. It is recommended that truck drivers open the windows for about one minute in advance to dissipate heat before turning on the air conditioner. This will not only save power, but also make the interior environment cooler and more comfortable.
Charging while using is not advisable
During daily charging, high-power electrical appliances should be disabled. Using air conditioners, seat heating and other equipment during charging will cause the battery to frequently switch between charging and discharging states, accelerating aging. Actual measurements show that turning on the air conditioner while charging will extend the charging time by 15%-20%.
Note: The cumulative daily charging power should not exceed 1.5 times the current power as much as possible.
Regular inspections and good habits
Regular inspections are an essential part for both traditional fuel trucks and new energy trucks. Before driving, truck drivers need to observe the status of the vehicle dashboard to ensure that the battery system is in normal condition and start on the road without abnormal alarm information.
If the mileage of a new energy vehicle drops significantly during use, it is likely that there is a problem with the battery pack. At this time, you should go to the service station for inspection in time.
Battery maintenance, do it regularly
In the daily operation of cardholders, regular battery maintenance is also essential. Normally operating vehicles must perform “battery maintenance” at least once a year, and vehicles that have not been used for a long time must perform “battery maintenance” every three months.
Battery maintenance method:
① The vehicle is parked in a spacious, flat and safe location, and a complete charging device is required here.
② Adjust the battery power (SOC) of the vehicle to within the range of 25%-40%.
③ After the vehicle stops, turn off the power (turn the key to OFF), then start the power (turn the key to ON), and turn off the on-board electrical equipment.
④ Keep the vehicle powered on (keep the key in ON) and let it stand for 12-15 hours without manual supervision.
⑤ After the standing time is over, a full charge is required.
