The reasons why an electric vehicle cannot start after being left unused for a long time are: 1. The power battery is depleted due to self-discharge; 2. The auxiliary battery is depleted from prolonged disuse; 3. The fuse of the starter motor is blown; 4. The steering wheel is locked in a stationary position; 5. The battery has reached the end of its lifespan and can no longer store power; 6. The starter motor gear cannot engage the flywheel. Solutions for an electric vehicle that cannot start after being left unused for a long time: 1. Check if the vehicle's ignition system is functioning properly; 2. Check if the vehicle's battery has sufficient charge; 3. Check if the battery is damaged; 4. Check if the starter motor's fuse is blown.
I usually drive to and from work, but once when I came back from a business trip lasting several months, I found my electric car wouldn't start. The reason was that the battery had drained itself, especially lithium batteries which slowly discharge when left unused for long periods. Those onboard computer systems, like the anti-theft and navigation, also quietly consume power. Later, I asked a mechanic friend, and he said leaving the battery deeply discharged for too long can damage it, making it unable to start. He advised not leaving the car unused for more than a month, and it's best to plug in the charger every week or every two weeks to top up the charge. If you plan to park it long-term, buy a maintenance charger to keep the battery level stable. After that experience, I learned my lesson, and now every time I go on a business trip, I ask someone to help charge it occasionally.
