The use of electric vehicles can be seen from the figures that can be seen everywhere on the street, but electric vehicles always seem to have some problems. How much do you know about these common faults? Let’s take a look at the secrets revealed by electric experts Common faults of electric vehicles!
Common faults of electric vehicles 1: The motor does not rotate, and the instrumentation is normal
1. Unplug the socket of the brake lever. If the motor is running, the brake lever is faulty, and the brake lever should be replaced.
2. If the voltage does not change or is less than 1V when the voltage is detected, the handlebar is faulty or the handlebar wire is short-circuited.
3. Check the motor Hall signal line. If the voltage does not change, the motor Hall is damaged. If each voltage conversion is normal, the controller may be damaged.
Two common faults of electric vehicles: the motor stops when it rotates
1. When the voltage of the battery is in a critical state of under-voltage, it will turn on and off.
2. This fault will also occur if the battery connector is not in good contact.
3. The line of the speed control handle should be broken and the brake power-off switch is faulty.
4. The power lock is damaged or the contact is poor, the line is connected to the plug-in program and the connection is not good, and the components in the controller are not welded firmly.
