Fault Analysis Of Electric Classic Cars

Analysis of the reasons why electric classic cars cannot be charged:
1. Fault phenomenon:
The ammeter pointer returns too quickly while driving after starting, or the battery temperature of the electric classic car is too high, and the ammeter pointer still points above +5A after driving for a long time.
2. Cause of failure:
(1) Battery damage in electric classic cars.
(2) There is an internal short circuit fault.
(3) The active material on the plate falls off, causing the capacity to be too small.
(4) The plate is vulcanized or the negative plate is hardened.
3. Troubleshooting and troubleshooting:
For fault diagnosis of electric classic car battery failure to charge, judgment must be made based on a comprehensive analysis of the fault phenomenon and its usage. If the electric classic car battery has been used for more than a year and the above phenomenon occurs, it is generally because the electric classic car battery has been exhausted and should be replaced with new parts. If the battery temperature of an electric classic car is too high and the ammeter pointer still points above +5A after driving for a long time, you can use a high-rate discharge meter to find out. If the measured voltage of a single cell is lower than 1.5V, it means there is a short circuit fault in this single cell and it should be disassembled and repaired.
