What are the conditions that cause the battery to charge up?

The charging time of an electric vehicle cannot be too long, usually 8-12 hours. If the battery is charged repeatedly for a long time, it is easy to cause the battery to be charged due to overcharging. The charging time is too long, resulting in the battery charging drum accounting for about 15%. The second charging current is too large, the battery will be charged: long-term use of the fast charging station on the roadside will also charge the battery, because the working principle of the fast charging station is to charge a large current for a period of time, which will cause serious gas loss and water loss of the battery , The battery bulge. Third, if you use chargers of different specifications indiscriminately, the battery will be charged: If you use chargers of different specifications, the rated voltage, voltage and current of the charger will not match the battery. Not only will the battery be charged, but it will even explode. The fourth long-term charging battery will be charged in a high temperature environment: the normal charging mode should be: depending on the battery power, in summer, the charger should stop charging after turning the green light, and the charger can float 3-4 after turning the green light in winter When the ambient temperature is high, after riding, the surface temperature of the battery should be allowed to cool down before charging to prevent charging in a high temperature environment. Fifth, the damaged charger will make the battery charge drum: the electronic components on the main board of the electric vehicle charger are welded, some large electronic components, bumps and vibrations may cause desoldering, lead to poor contact, and cause current instability during charging And the protection function fails, causing the battery to be charged.
