What Could Be the Reason for a Pure Electric Vehicle Failing to Start?
2 Answers
Possible reasons for a pure electric vehicle failing to start include: Carbon buildup: Difficulty in ignition caused by carbon buildup in the car, accompanied by slight shaking at idle. Cleaning the throttle valve, intake tract carbon deposits, and fuel injectors can solve the problem. Weak energy: Weak ignition energy from the spark plugs can lead to decreased spark plug ignition energy, causing misfires in severe cases. Many current vehicle models feature direct-injection engines, which place higher demands on spark plugs. Low pressure: Insufficient low pressure in the fuel system can directly cause the engine to require a second ignition. The specific reason is that the first ignition attempt fails because the low-pressure fuel system is building up fuel pressure, while the second attempt succeeds. Components to check specifically: fuel pressure regulator, fuel pump, fuel filter, and fuel lines. Battery depletion: Battery depletion is a more common issue. When the car fails to start, the first reaction of many owners is that the battery is dead. The solution is also simple: just jump-start the car using another vehicle or battery.
I've been driving a pure electric vehicle for over five years and have encountered several startup issues. The most common problem is insufficient charge or aging of the 12V auxiliary battery, which can prevent the car from starting, especially during cold winter starts when resistance increases. A depleted high-voltage battery pack can also cause startup failure—remember to check your charging history to see if it didn’t charge properly or if there was poor port contact. Software glitches are also common; just like a frozen phone, restarting the system might help. Loose charger connections or vehicle safety systems, such as an unreleased brake, can also block startup. I recommend first checking the small battery indicator, confirming the charging status, and trying to reset the onboard computer. If the issue persists, visit a 4S shop as soon as possible, since high-voltage components pose risks and shouldn’t be tampered with. Regular maintenance of the 12V battery and avoiding excessive discharge can prevent most issues—my friend once had to call a tow truck because he left the lights on and drained the battery.
