My electric car 48V charging when the battery is very hot charge a night are dissatisfied with what is going on?

When my electric car is charged 48V, the battery is very hot and charging for one night is a typical manifestation of battery aging. First, the sudden start and sudden braking of electric vehicles will seriously consume battery power, so the slow start and moderate speed smooth cycling can increase the battery use time. Second, the battery should not be used up before charging, which seriously affects the battery life and even damages the battery. Electric vehicle battery shows insufficient power, do not continue to use, although the car can ride a road, but this may cause the battery to run out of power, and seriously shorten the life. Third, if the battery is not used for a long time, it must be fully charged before storage, otherwise, because the battery will finish the power in the natural state, and seriously shorten the life. Fourth, the battery is strictly prohibited from being used in parallel or in series with other lithium batteries or lead-acid batteries, otherwise, the battery will be damaged due to overcharge and overdischarge of some batteries. Fifth, do not let the battery shake in the battery box, otherwise, the battery is very easy to be shaken. Six, because the lower the battery voltage, the greater the internal resistance, the more exhausted the battery heat will be greater during the driving process. Therefore, the battery with charge is the best maintenance for the battery, generally with half of the charge is almost, at most, there is 30% of the power to be charged in time.


The reasons for the battery charging and heating are as follows:

1. Battery aging, battery water loss, and battery plate vulcanization are easy to cause the battery to flush and heat up the battery;

2, line damage;

3. Poor fuse contact;

4, the internal plug-in contact is poor;

5. The charger is damaged;

6. Circuit board failure.

Solution: 1, replace the battery.

2, repair line damage.

3, maintenance fuse contact is poor.

4, repair the internal plug-in.

5, repair and replace the charger.

6. Repair the circuit board.
