Why Won't a Four-Wheel Electric Car Move Despite Having Power?
2 Answers
Accelerator (throttle) internal Hall element damaged, recommended replacement; Brake power-off system stuck or not reset, suggested to reset it; Control circuit shorted or controller malfunction, replace necessary components; Motor failure, recommended to go to a repair shop for inspection and repair. The specific reasons why a four-wheel electric car won't move despite having power are as follows: Check if the electric vehicle's battery output is normal: If the output is too low, it indicates battery damage, requiring battery replacement. Handbrake cable broken: If the wheel turns, it proves the brake handle is faulty and must be replaced. Check the throttle handle: Use a wire to short the throttle handle's positive and signal wires; if the car moves, it indicates a faulty throttle handle, requiring replacement or repair. Turn on the power and twist the throttle handle, use a multimeter to measure the positive and signal wires;
I've been driving a four-wheel electric vehicle for several years and have encountered quite a few situations where it wouldn't move despite having power. Usually, it's not a dead battery but other issues causing trouble. For example, the motor's overheating protection kicks in, especially after frequent uphill climbs or high-speed driving, causing the vehicle to automatically shut down to prevent damage. Or the transmission system gets stuck, like gear wear or bearing problems, requiring a check on whether the wheels rotate smoothly. There's also the controller malfunctioning, similar to a phone freezing, where sensor errors cause signal interruptions. The simplest solution is to restart the ignition or wait a few minutes for cooling. If the dashboard warning light comes on, immediately check the manual for error codes. Regular maintenance focusing on these areas can prevent issues before they require repairs. If the problem persists, don't push it—safety first, take it to a professional shop for inspection.
