What is the cause of the electric car battery?

1. The first is that the processing manufacturing process is unqualified. If the electric vehicle market is mixed, many companies are limited due to the limited manufacturing level of the battery, and the electrode coating is not average, and there is no stain to the battery.

Such a battery is extremely easy to drum. 2. Battery overshoot.

The battery overshoot is easy to cause fire, and on the other hand, it will also cause battery drums. The battery overshoot will cause a lot of heat, causing electrolyte analysis and gasification, and the battery is drumping. 3.

The charging current is excessively, many owners have changed their battery and electric cars. In addition, the owner is cheap to buy cheap mismatched chargers, and the different sizes of batteries have a specified voltage current. If the charging current is too large, it causes the electrode The precipitation of the board is too fast, causing the chemical reaction, too high, and if the exhaust is not in time, there will be a phenomenon of battery drums.

4, the safety valve pressure is high, the electric car battery has a safety valve in order to ensure safety, when the pressure in the electric vehicle battery rises, the safety valve will automatically open, perform pressure to ensure battery Internal and external air pressure balance. If the pressure is rising in the battery, the safety valve cannot be opened normally. Over time, due to the high pressure in the battery, the internal and external gas pressure is unbalanced, there will be a phenomenon of drums.

Drums are one of the many phenomena, of course, is also a common battery problem, and the battery of electric vehicle will have lost water, imbalance, sulfate, polar plate softening, etc., which affect the battery life.
