Why can't new energy vehicles be fully charged?
2 Answers
The reasons why new energy vehicles cannot be fully charged are as follows: Short circuit fault: When a small battery in the electric vehicle battery pack has a short circuit fault, charging the electric vehicle at this time will result in the charging light not turning off, which is commonly referred to as the inability to fully charge. For such issues, the general solution is to replace the entire battery pack, which can resolve the problem of the charging light not turning off. Water loss fault: This situation is relatively common. Generally, if an electric vehicle battery has been used for more than three years, water loss faults often occur. It usually manifests as severe heating of the battery during charging, and the charging light not turning off.
I've encountered the issue of new energy vehicles not charging fully several times, which is quite annoying. The most common reason is battery aging – after prolonged use, the capacity naturally decreases, resulting in noticeably shorter range even when fully charged. Temperature has a significant impact; batteries don't charge well in extreme winter cold, and high summer temperatures aren't ideal either. Charging stations can also malfunction, with issues like unstable output current or loose connectors – I once tried different stations and found only one could charge to full. Software glitches may interfere too; sometimes the vehicle's battery management system works fine after an update. Don't overlook daily habits – avoid waiting until the battery is completely drained to recharge, as this accelerates battery wear. I recommend paying attention to ambient temperature, preheating the battery appropriately before charging when necessary. If this happens frequently, it's safer to get a comprehensive check at a 4S shop. Never compromise on safety – after all, the battery is the core component of an electric vehicle.
