Six Tips for Electric Vehicle Battery Protection

The length of electric vehicle mileage is one of the main criteria for consumers to measure the quality of electric vehicles. As we all know, electric vehicle battery has played a decisive role, then the maintenance of electric vehicle battery should pay attention to what problems? The research team of the Battery Research Institute of the National Chung Hwa University Research Institute summed up the battery maintenance techniques for reference:

One: Forbidden to lose electricity when stored

When the battery is stored in a depleted state, sulfation is likely to occur. Lead sulfate crystals adhere to the plate, blocking the ion channel, resulting in insufficient charging and decreasing battery capacity. The longer the idle state of idle state, the more severe the damage to the battery. Therefore, when the battery is not used, it should be recharged once a month, so that it can maintain the battery health.

Two: regular inspection

If the mileage of an electric vehicle suddenly drops by more than ten kilometers in a short period of time, there is a possibility that at least one of the batteries in the battery pack has a broken cell, softened plate, and active plate peeling off. At this time, it is necessary to promptly go to a professional battery repair facility for inspection, repair or matching. This can relatively prolong the life of the battery pack and maximize savings.

Three: Avoid large current discharge

When an electric vehicle starts, carries a person, or goes uphill, use an ankle to help and try to avoid instantaneous high-current discharge. The large current discharge easily leads to the production of lead sulfate crystals, thereby impairing the physical properties of the battery plates.

Four: correctly grasp the charging time

In general, the batteries are charged at night and the average charging time is about 8 hours. When the battery is discharged with a depth of 60%-70%, it is best to charge one time. When it is actually used, it can be converted into riding mileage. According to the actual situation, necessary charging can be performed to avoid harmful charging.

V: Prevent exposure

The excessively high temperature environment will increase the internal pressure of the battery and cause the battery pressure limiting valve to be forced to open automatically. The direct consequence is to cause the battery activity to decrease, accelerate the plate to soften, and cause the shell to generate heat, the housing drums, deformation and other fatalities during charging. damage.

VI: Avoid plug heating when charging

Loss of the charger output plug, contact surface oxidation and other phenomena will cause the charging plug to heat up. If the heating time is too long, the charging plug will short circuit, which will directly damage the charger and cause unnecessary losses.
