What are the reasons why an electric vehicle cannot start?

Reasons why an electric vehicle cannot start: 1. The battery is dead; 2. The controller is damaged; 3. There is a circuit malfunction. After encountering this situation, it is necessary to go to a professional repair facility for inspection and repair. Electric vehicles refer to vehicles that use electrical energy as a power source and are driven by electric motors. They belong to the category of new energy vehicles, including pure electric vehicles (BEV), hybrid electric vehicles (HEV), and fuel cell electric vehicles. Taking pure electric vehicles as an example, they are vehicles driven by electric motors. Compared to fuel-powered vehicles, the main differences of pure electric vehicles lie in four major components: the drive motor, speed controller, power battery, and onboard charger.
As an owner who has driven an electric vehicle for several years, I often encounter situations where the car won't start. The most common issue is a depleted 12V auxiliary battery, which is used for the starting system - if it's low on power, it simply refuses to work. The main high-voltage battery can also cause starting failure if it's not fully charged or damaged. Regarding charging, a loose charging gun or dusty charging port might prevent proper charging. Software issues are also frequent; when the screen freezes, try holding the start button for 15 seconds to reboot. In winter, battery efficiency drops, so parking in a garage or preheating helps. Once my car wouldn't start in sub-zero temperatures, and roadside assistance found the auxiliary battery had aged - replacing it solved the problem. I recommend regular battery checks and consulting professionals when issues arise - safety first, never force solutions.
Honestly, the issue of electric vehicles failing to start is quite annoying. I believe the auxiliary battery is the main culprit - when its charge is too low, the car won't start. The main battery needs sufficient charge, and if the charging display shows abnormalities, it might be due to a loose charging connector or dirty charging port. Occasionally, software glitches may occur, but a system reboot usually fixes it within minutes. In extremely cold weather, battery response slows down, so parking indoors helps. Last time I accidentally left the lights on and completely drained the auxiliary battery - had to get it replaced at a roadside shop to get back on the road. Now I've developed a habit of checking the charging status every night to avoid troubles. Remember, if the vehicle fails to start, don't repeatedly attempt it as this might cause more issues with the electronic control system - contact the 4S shop directly instead.
