Why does the electric car not charge and stay green when left for a long time?

If the electric car does not charge and the light stays green, it is likely due to a battery failure. The reasons for not charging and the light staying green are as follows: Charger converter or fuse damage: If the electric vehicle charger light stays green, the first aspect to consider is whether the charger has a fault, which is generally manifested as converter or fuse damage. If the converter is damaged, the charger cannot convert and charge normally, resulting in the electric vehicle not charging and the light staying green. Failure of a small battery in the battery pack: Another aspect to consider is whether there is a battery fault, which is generally manifested as a short circuit in one of the small batteries in the battery pack. In this case, if you charge the electric vehicle, the charger will continue to show a green light and not charge. Loose or poor connection of the wiring: The third aspect to consider is whether there is a loose or poor connection in the wiring, which is generally manifested as a loose interface or corrosion causing a poor connection. The correct solution is to unplug and replug the charger to see if the light changes from green to red. If it does not, then you need to check whether the interface is corroded. If so, the wiring needs to be replaced.
I've repaired many electric vehicles where the charging light stays green but the battery won't charge, usually due to deep discharge. When batteries sit unused for long periods, their internal chemicals degrade, causing the charge level to drop very low. The charger thinks it's fully charged (hence the green light), but actually no power is going in. First check if the connectors are loose or corroded - try unplugging and replugging a few times. If that doesn't work, the battery management system might be locked, requiring a professional charger to wake it up or taking it to a repair shop for voltage testing. Try not to leave your EV unused for too long - charge it every week or two to keep the battery active. Battery lifespan is greatly affected by temperature - both extreme heat and cold can accelerate aging, so store your vehicle in a cool, dry place when possible.
