What to do if the Emma electric vehicle suddenly stops moving but still has power?
2 Answers
Solutions for when the Emma electric vehicle suddenly stops moving but still has power: 1. Unplug the brake handle socket. If the motor runs, it indicates a faulty brake handle, which should be replaced; 2. Check the throttle signal voltage. The signal voltage should change from 0.8V to 4.2V from low to high. If the voltage does not change and is less than 1V, it indicates a faulty throttle or a short circuit in the throttle wire; 3. Check the motor Hall signal wire. If the voltage does not change, it indicates a damaged motor Hall sensor, and the motor or motor Hall component should be replaced. The reasons why the Emma electric vehicle suddenly stops moving but still has power are: 1. Damaged brake handle; 2. Damaged throttle; 3. Damaged motor; 4. Damaged controller.
I also encountered the strange situation where my electric vehicle had power but wouldn't move last time. It felt really awkward. Don't panic first, it's likely caused by some minor issues. The most obvious thing to check is the braking device to see if it's stuck. Sometimes the brake sensor is too sensitive and cuts off the power supply. Also, try rotating the throttle handle back and forth a few times—it might be poor contact. Then check the tires underneath the vehicle to see if anything is stuck in the drive chain. These are common issues, and I've dealt with them a few times myself. Just loosen the brake point with a wrench and then tighten it, or unplug and replug the controller connection wires, and it usually solves the problem. If none of these work, the controller might be broken or there could be an internal motor fault, in which case you'll need to go to a repair shop. It's best to keep a small toolbox in your vehicle for emergencies. In short, safety comes first—don't spend too much time fiddling on the roadside.
