It may be that the charging line of the electric vehicle has poor contact; Or it could be the charger. ;
Solution: Please ask a professional teacher to test the electric car, according to the actual situation for maintenance or new car battery replacement. ; The correct way to charge electric vehicles:
1, to maintain the battery full state, every day riding electric moped, regardless of 10-50km, should be added to charge, so that the battery in a \"full state\" for a long time, and the same day charged, used up idle for a few days and then charged, prone to plate vulcanization, capacity decline.
；
2, regular deep discharge: it is recommended that you use two months after a deep discharge, that is, long-distance riding until the undervoltage light shines, the power is used up, and then charge to restore the battery capacity, but also make you understand the current capacity level of the battery, whether it needs to be maintained and protected.
；
3, no loss of power storage: battery loss of power storage will seriously affect the service life, if the idle time is longer, the more serious the battery damage. ; Extended data:; Electric vehicle, that is, electric drive car, also known as electric drive. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally, electric vehicles use batteries as energy sources, and convert electrical energy into mechanical energy movement through controllers, motors and other components to control the size of the current and change the speed of the vehicle. ;

The electric car charger breaks the charge for a while, which is the reason for the charger, because the charger is charging the battery, because the power tube is a heating element, it will generate a lot of heat, and it is possible to burn the charger due to overheating. Secondly, there are battery reasons, battery due to aging, resulting in a significant reduction in battery capacity, resulting in a full battery for a while, it is recommended to replace the new battery in time.
The reason is that the vehicle charging interface line is virtual. The poor contact of the charging interface line of the vehicle will lead to frequent gun jumping after the charging gun is inserted into the charging interface of the body, and the vehicle cannot be charged normally.
The maintenance technician will power off the vehicle, remove the liner at the front charging interface of the vehicle, and check whether the charging interface line is damaged and whether the line interface is loose.
The charger or battery is faulty.
< br >
The electric car charger will charge for a while and not charge for a while, generally caused by the failure of two places:
< br >
1, charger failure: When the charger charges the battery, because the power tube is a heating element, it will generate more heat. If the charger voltage output part of the circuit of the component performance is poor, or the component pin welding, it will cause the fault to appear due to the charger temperature rise, but the charging stops; After the charger stops working for a time, the internal temperature of the charger decreases, the components return to normal state, and the charger starts to work again.
< br >
Solution: Open the charger shell, first check whether there is a virtual solder spot, if there is a soldering iron can be welded; If there is no component welding, it is necessary to check the performance of the component itself, especially the power tube.
< br >
2, battery failure: After the charger is full of the battery, the voltage comparison circuit will send a signal, and the charger will stop charging the battery. However, if the battery itself is faulty due to aging and other reasons, such as a serious decline in storage capacity and serious self-discharge phenomenon, it will cause the battery voltage to drop when the charger plug is not pulled out, and the charger starts to work again.
