What are the reasons why an electric vehicle won't start?
2 Answers
Electric vehicles may fail to start for the following reasons: 1. Poor connection of wiring: If the wiring becomes loose or corroded due to external factors, poor contact may occur. In this case, the electric vehicle may appear to have power when unloaded, but it actually cannot start. To address this issue, professional testing equipment is needed to locate the poor connection, followed by wire replacement and repair. 2. Motor malfunction: If the motor malfunctions, it will hinder the operation of the entire electric vehicle. For this problem, it is necessary to visit a specialized electric vehicle repair shop. 3. Loose or detached power wires: As the brain of the electric vehicle, the controller is often the most overlooked important component. Many electric vehicle users experience situations where the vehicle has power but won't start, and a very direct reason is that the power wires have become loose or detached.
I once encountered a situation where my electric vehicle wouldn't start, which really stressed me out. It turned out to be caused by a depleted small 12V auxiliary battery. This secondary battery powers the startup system, and once it ages, the car becomes completely unresponsive. At the time, I first checked the charging status, which showed full, but the dashboard had a red warning light; trying to remove and reinsert the key card didn't help, and I eventually had to call for roadside assistance, which diagnosed the battery as faulty. Remember, unlike gasoline cars, EVs don't have traditional ignition components, but cold temperatures or prolonged parking can accelerate the aging of small batteries. It's recommended to check the battery voltage every six months—don't skimp on this to avoid being stranded and delayed. It's also a good habit to routinely start the vehicle's system while charging to confirm everything's working properly.
