There are usually several reasons why lithium batteries in electric vehicles cannot be charged in winter:
1. Battery life is over
Solution: Replace or repair the battery. .
2. The battery fuse fuse is broken.
Solution: Replace the fuse.
3. There is poor contact between the battery safety tube and the safety seat.
Solution: Adjust the position of the two to make good contact, or replace the fuse.
4. Charger has no or low output voltage
Solution: Replace or repair the charger.
5. There is poor contact between the charger and the 220V AC power supply.
Solution: Disconnect the power supply.
6. The charger indicator light is abnormal, causing improper charging.
Solution: Replace or repair the charger.
7. There is no voltage between the positive polestif and negative of the dial
Solution: The connector is in poor contact or disconnected: reconnect or replace the wire.
8. The light tube is damaged
Solution: Replace or repair the light tube.
9. There is a circuit break on the dial circuit board.
Solution: Replace or repair the instrument circuit board.

Remarks:
Proper use can extend battery life to a certain extent.
1. Do not charge while driving.
Battery life is determined by the number of charge and discharge cycles. The more you charge and discharge, the faster the lifespan decreases. Therefore, you should not charge your electric car just for driving, but when the maximum battery life is 60-70%.
2. Charging time does notshould not be too long
Many electric vehicle users think that the longer the charging time, the greater the battery energy. This is very wrong. Charging time is usually extended within an hour after replacing the charger. Prolonged overcharging can easily cause battery deformation, water loss, etc. This directly harms battery life.
3. It's best to use smart plugs
Many electric car users charge when they get home from work, and then turn off the power when they go to work the next day. . In fact, most chargers are not guaranteed to automatically cut off power when the battery is fully charged. The best way is to buy a smart plug and set the charging time, so you can solve the problem of sleeping at night.
4. It is strictly prohibited to lose power during exercise
The electric bike cannot be charged until it can move, this will seriously damage the battery performance. Multiple deep discharges can significantly reduce battery life. If the battery is low on the road, it is best to pedal in advance to avoid deep discharge.
5. Do not charge at too high or too low a temperature
During the charging process, the battery itself will produce a small amount of heat. Charging at too high a temperature will increase the bottle temperature and damage battery performance. The temperature is too low. The battery acceptance capacity is low, the activity is weakened, the battery power is insufficient, the number of charging and discharging times increases, and the battery life is shortened.
