Electric vehicle lead-acid batteries have "three fears"

1. Fear of excessive discharge

When the battery is charged, the lead-acid compound crystals on the electrode plate will be released into the electrolyte, and when the battery is discharged, lead-acid compound crystals will be formed on the electrode plate. If it is over-discharged for a long time, the crystals on the battery electrode plate will accumulate larger and larger. Since these crystals cannot be fully dissolved during charging, the actual capacity of the battery will become smaller and smaller, and the service life of the battery will be shortened.

2. Fear of severe vibration

There are many layers of electrode plates inside the electric vehicle battery. If the battery is subjected to excessive external vibration, it is likely to damage the internal physical structure of the battery, causing the electric vehicle to leak liquid, and at the same time, it will also cause the battery to suddenly appear due to loose port lines. In case of power outage.

3. Afraid of high temperature

According to relevant research data, when the battery is in an environment of 45°C, the lifespan will be shortened by 40%. Therefore, the battery life we ​​work in high temperature areas will be much shorter than that in low temperature areas. Because the higher the external ambient temperature, the more active the chemical reaction of the battery is, and the more obvious the corrosion effect on the electrode plate, thereby accelerating the water loss rate of the battery, so the electric vehicle is very afraid of charging in a high temperature environment, and also afraid of being in a high temperature environment. drive down.
