What are the reasons for the bulging of UPS batteries?

The charging time of an electric vehicle cannot be too long. If it is repeatedly charged for a long time, it is easy to cause the UPS battery to be overcharged and charged. According to actual research data, the charging time is too long, which causes the battery to charge up, accounting for about 15%. Second, the charging current is too large and long-term use of the fast charging station on the roadside will also charge the UPS battery. Because the working principle of fast charging stations is high-current charging, this will cause serious battery loss and cause battery swelling. Third, use different chargers indiscriminately. If chargers of different specifications are used indiscriminately, the rated voltage and current of the charger will not match the battery. Not only will UPS battery charge drums, but also explosions. Fourth, the normal charging mode for long-term charging in a high temperature environment should be: depending on the battery power, the charger can float for 2 hours after turning the green light. If the ambient temperature is high, do not charge after the end of the ride. The correct method is to allow the battery surface temperature to cool naturally before charging. Long-term charging in a high temperature environment will cause the battery to charge up. Fifth, use the damaged charger. The electronic components on the charger motherboard of the electric vehicle are welded. For some large electronic components, bumps and vibrations may cause desoldering, resulting in poor contact, resulting in unstable current and protection during charging. The function fails, causing the UPS battery to charge up. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
