Reasons why the battery of an electric vehicle cannot be charged

1. Battery aging

When the battery is aging, it cannot be brought back to life through repair, and it can only be scrapped.

2. The battery loses water

When the battery loses water, the battery can still be used after replenishing water according to the regulations.

3. Battery plate vulcanization

If the electrode plate is vulcanized, the charging and discharging will show that the voltage rises rapidly and the capacity is obviously reduced. The sulfur removal device should be used to restore the electrode plate and restore its activity.

4. The line is broken

Check whether the connection of the charging circuit is reliable, check whether the connection between the connection and the plug is in good contact, and carefully check whether the socket box plug has "fire" arcing phenomenon, whether there is line damage, disconnection, etc. Check whether the charger is damaged and whether the charging parameters meet the requirements.

5. Poor fuse contact

When the contact between the fuse and the fuse seat is poor, the battery will not be charged or not fully charged. As long as the positions of the two are adjusted so that they are in good contact, the problem will be solved.

6. The internal plug-in is in poor contact

The plug-in in the battery is in poor contact or the lead is broken, which will also cause the battery to fail to charge. Just re-plug or change the cable to restore normal charging.

7. The charger is broken

When the charger cannot be charged, but the indicator light is still on, we will mistakenly think that it is charging all the time, but in fact it cannot be charged at all!

8. Circuit board failure

When the circuit board in the dial has an open circuit, it will also cause the battery to fail to charge, as long as the circuit board is replaced or repaired.
