What to Do When an Electric Vehicle Shakes and Fails to Move?
3 Answers
Here are the solutions for an electric vehicle that shakes and fails to move: 1. Battery: Check if the battery output is normal. If the output is too low, it indicates a faulty battery that needs immediate replacement. 2. Controller: To test the controller, short-circuit the positive 5V of the throttle wire. If the throttle turns, the controller is fine. The simplest method is to smell for any burnt odor from the controller. 3. Throttle: Inspect the throttle by short-circuiting the positive and signal wires with a piece of wire. If the vehicle moves, the throttle is faulty and needs immediate replacement or repair. Turn on the power and use a multimeter to measure the positive and signal wires while twisting the throttle. 4. Motor: Check the motor's condition. Poor contact of the motor's carbon brushes can also cause the vehicle to have power but not move. 5. Brake: Disconnect the brake wire. If the vehicle moves, the brake handle is damaged and needs replacement.
Last time I drove an electric car, I also encountered the annoying problem of shaking and being unable to move. After parking, I found out it was caused by a loose high-voltage battery connection and unstable current. You can try pulling over, turning off the car, and restarting the system—remove the car key, wait 10 seconds, and then turn it on again. Check if the tire pressure is insufficient and see if there are any warning lights on the dashboard, like a red battery icon indicating a charging issue. Don’t force the car to drive, as it could damage the motor. It’s best to regularly take your electric car to a 4S shop for battery health checks to avoid minor issues turning into major repairs. Battery aging is also a common cause, leading to reduced range—replace it when necessary.
The electric car won't move and keeps shaking? Most likely it's a problem with the motor or controller. First, find a safe place to park and turn on the hazard lights. Try gently pressing the accelerator pedal to see the response, and restarting the system might solve software bugs. For older models, a depleted battery can also cause shaking—use the original charger when charging. Regular maintenance should pay attention to the wheel axles and suspension system; if they're damaged, the car will wobble when driving. New car owners shouldn't panic—simple operations can fix it, and don't try to disassemble parts yourself to avoid trouble.
