1. affects battery life.
Lithium batteries for electric vehicles have low self-discharge rate. However, if the electric vehicle is charged for a long time, the service life of the lithium battery will be affected, and the temperature of the battery will be higher than normal, which will also affect the service life of the battery.
2. Affect battery performance
Charging an electric vehicle for a long time will affect the performance of the battery. When the lithium battery is in the charging state for a long time, it will affect the charging and discharging performance and the use effect of the battery, thus affecting the normal use of the electric vehicle.
3. Increase battery safety hazards
Long-term charging of electric vehicles will lead to excessive battery voltage, and too high voltage will lead to overheating of batteries. If you don't turn off the charging in time, it will cause a short circuit of the battery and even a safety hazard.
4. Shorten battery life.
Charging an electric vehicle for a long time will reduce the cruising range of the battery. This is because the battery will have a "memory effect" during charging, which will affect the battery's cruising range.
5. Produce radiation pollution
If the battery is charged for a long time, it will produce radiation pollution, which will affect people's health, and the temperature of the battery will be higher than normal temperature, which will also produce certain thermal pollution.
