What are the reasons for an electric four-wheeled vehicle being powered but not moving?
2 Answers
Electric four-wheeled vehicle being powered but not moving: reasons and solutions are as follows: Controller issue: Turn on the electric vehicle's power lock, use the multimeter's DC 20V range to measure the voltage between the red and black wires of the controller's throttle. If normal, the controller fault can be basically ruled out. Motor fault: Use the multimeter's DC 20V range, connect the black probe to the black wire of the Hall sensor group, the motor voltage should show a sequential high and low change. If there is no change or no voltage, it can be determined that the motor's Hall sensor is damaged. Wiring fault: Turn off the electric vehicle's power lock, use the multimeter's resistance range or buzzer range to measure whether the three connecting wires from the throttle to the controller on the wiring harness are conducting.
Electric four-wheelers power on but don't move – I've fixed this issue many times, and there are quite a few possible causes. The most common is battery problems; it might appear charged but actually have insufficient voltage, preventing the controller from activating. The controller, acting as the brain, could have burnt internal chips or software glitches requiring a reset. As for the motor, if bearings are jammed or carbon brushes are worn, it won't rotate even with power. Transmission system issues like gearbox or differential failures can also lock up the vehicle. Additionally, loose or corroded wiring harness connectors interrupting current might be fixed by simply reconnecting them. Once, I encountered a stuck brake system where the caliper didn't release, creating tire resistance—a gentle push freed it. Lastly, environmental factors like frozen components in cold weather suggest checking basics first before seeking professional help to avoid safety risks.
