1. Fault Phenomenon: After starting, the ammeter pointer returns to positive too quickly while driving, or the Foton Electric Car battery temperature is too high, and the ammeter pointer still points above +5A after a long period of driving.
2. Fault Causes
(1) Battery wear and tear.
(2) Internal short circuit fault.
(3) Active material loss from the plates, resulting in insufficient capacity.
(4) Sulfation of the plates or hardening of the negative plate.
3. Fault Diagnosis and Troubleshooting: For diagnosing the problem of an Foton Electric Car battery not charging, a comprehensive analysis of the fault phenomenon and its usage is necessary.
If the Electric Car battery has been used for more than one year and the above phenomena occur, it is generally because the Electric Car battery has worn out and should be replaced with a new one.
