Xiaobian teaches you how to maintain the electric car battery

Nowadays, electric vehicles are favored by consumers because of their light and pollution-free advantages. The length of mileage is one of the main criteria for consumers to measure the quality of electric vehicles. It is worth mentioning that in many electric vehicle quality complaints, the battery problem accounts for more than 95%, because the battery is an important factor in determining the length of the electric vehicle. So what problems should be paid attention to in the regular maintenance of electric vehicle batteries ?

It is strictly forbidden to lose electricity when storing

The battery must not be in a deficient state when it is stored. The deficient state means that the battery is not charged in time after use. When the battery is stored in a depleted state, it is prone to sulfation, and the lead sulfate crystals adhere to the electrode plate, blocking the ion channel, resulting in insufficient charging and a decrease in battery capacity. The longer the idle state is idle, the more severe the battery is damaged. Therefore, when the battery is not in use, it should be replenished once a month, which can better maintain the health of the battery.

Regular inspection

In the course of use, if the mileage of the electric vehicle suddenly drops by more than ten kilometers in a short time, it is very likely that at least one battery in the battery pack has a short circuit, such as a broken grid, softening of the plate, and falling off of the active material of the plate. . At this time, you should go to the professional battery repair organization for inspection, repair or matching. This can extend the life of the battery pack relatively and save the maximum cost.

Avoid large current discharge

When the electric car starts, carries people, and goes uphill, please use the ankle to assist, try to avoid instantaneous large current discharge. High current discharges tend to cause the formation of lead sulfate crystals, which impair the physical properties of the battery plates.

Correctly master the charging time

In the process of use, you should accurately grasp the charging time according to the actual situation, refer to the usual use frequency and mileage, and also pay attention to the capacity description provided by the battery manufacturer, as well as the performance of the supporting charger, the magnitude of the charging current and other parameters to grasp the charging frequency. . In general, the battery is charged at night, and the average charging time is about 8 hours. If it is a shallow discharge (the mileage after charging is very short), the battery will soon be full. If it continues to charge, it will overcharge, causing the battery to lose water and heat, reducing battery life. Therefore, the battery charge is best when the discharge depth is 60%-70%, and can be converted into the riding mileage when actually used, and the necessary charging is performed according to the actual situation to avoid the harmful charging.

Prevent exposure

Electric vehicles are strictly prohibited from being exposed to sunlight. If the temperature is too high, the internal pressure of the battery will increase and the battery pressure limiting valve will be forced to open automatically. The direct consequence is to increase the water loss of the battery. The excessive water loss of the battery will inevitably lead to the decrease of battery activity, accelerate the softening of the plate, and charge the case. Body heat, the shell caused by fatal damage such as drums and deformation.

Avoid plugging when charging

Loose output plug of the charger and oxidation of the contact surface will cause the charging plug to heat up. If the heating time is too long, the charging plug will be short-circuited, which will directly damage the charger and cause unnecessary loss. Therefore, when the above situation is found, the oxide should be removed or the connector replaced.

7 times before the new car is fully charged

According to experts, the battery is in a "half full" state before use, commonly known as virtual power. The new car that the consumer just bought will be filled with 10-12 hours before the 7th time. After filling it for 7 times, it is necessary to ride with the ride, usually no more than 8 hours. The most scientific method is to charge the lamp to the full mark and then charge it for an hour. Don't wait until the battery is exhausted before charging, which makes it easy to "tired" the battery. In addition, if the vehicle is not used for a long time, it is necessary to fill the battery and put it again, otherwise the battery will "starve to death."

The procedure for charging an electric vehicle is to first turn off the electric vehicle power switch, plug in the charger, and then connect the 220V power supply. After charging is complete, disconnect the power supply and disconnect the charger.

It is best to pedal first when starting.

Don't be too troublesome to ride an electric car. It is best to ride with your feet first and then slowly accelerate. The battery is afraid of heat in summer, and it must not be exposed to open flames. Avoid direct sunlight. Use the charger to confirm the model, voltage and frequency to meet the requirements.

Every 2 months, you should discharge it deeply and charge it once.
