When Electric Car batteries cannot be charged, first check whether the circuit connection is in good contact, check whether the connection line is fixed, and carefully check whether the socket and plug are ignited and burnt, whether there is any line damage or disconnection, etc.
First, these external factors need to be eliminated, and then check whether the charger is intact and whether the charging parameters meet the requirements. Some users are used to carrying chargers with them, and it is very easy for the charger to be damaged and unable to charge due to bumps. Therefore, it is very important to check whether the charger is normal. It is also necessary to check whether the plate is sulfided.
1. You can unplug the brake line of the Electric Car. If it is still turning, it means that the brake handle is broken and should be repaired in time;
2. Check whether the battery output of the Electric Sedan Car is normal. If the output is too low, it means that the battery is damaged and needs to be replaced;
3. Check the handlebar, short-circuit the positive pole and signal line of the handlebar with iron wire. If the car turns, it proves that the handlebar is broken and needs to be replaced or repaired urgently. Turn on the power and twist the handlebar to measure the positive pole and signal line with a meter.
4. If the carbon brush of the motor does not make adequate contact, the Electric Sedan Car will not move even if it has power.
