Why does an electric car show power but not move?
2 Answers
Electric car showing power but not moving may be a controller issue. Below is relevant information about electric vehicles: Introduction: Electric vehicles (BEV) refer to vehicles that use on-board power sources as their driving force, with electric motors driving the wheels to meet all requirements of road traffic and safety regulations. Types: There are mainly three categories of electric vehicles: pure electric vehicles, hybrid electric vehicles, and fuel cell electric vehicles. Power source: Provides electrical energy to the driving motor of electric vehicles, and the motor converts the electrical energy from the power source into mechanical energy. The most widely used power source is lead-acid batteries, but with the development of electric vehicle technology, lead-acid batteries are gradually being replaced by other batteries due to their low energy density, slow charging speed, and short lifespan.
I remember that time when I was driving my electric car to work, the battery showed 70% remaining, but pressing the accelerator had no response at all, which really stressed me out. It turned out to be an issue with the controller—some oxidation at the interface caused a signal interruption. Later at the repair shop, the mechanic said common causes include sensor failure, aging of individual battery cells, or the braking system getting stuck. I’ve learned a bit myself: first, try restarting the entire vehicle system, which usually resolves temporary software glitches; check if the pedal wiring is loose; and also be mindful that humid weather can lead to circuit mold. In such cases, it’s best not to force the car to move—safely pull over and have a professional inspect it to prevent further damage. Regular quarterly maintenance can help reduce the chances of this happening.
