Is the battery dead if the electric vehicle won't charge?
2 Answers
The electric vehicle not charging may indicate a battery failure. The possible reasons and solutions are as follows: Battery End of Life: The battery has reached the end of its service life. Solution: Replace or repair the battery. Poor Fuse Contact: The fuse inside the battery is broken or there is poor contact between the battery fuse tube and fuse holder. Solution: Replace the fuse. Adjust their positions to ensure good contact, or replace the fuse tube. Low Voltage: The charger has no output voltage or low output voltage, or there is poor contact between the charger and the 220V AC power source. Solution: Replace or repair the charger; reconnect the power source. Abnormal Indicator Light: Abnormal charger indicator light causing false full charge. Solution: Replace or repair the charger.
When my electric scooter started failing to charge, I initially thought the battery was dead, but from personal experience, I found the issue could be varied. Battery aging is indeed common, especially after two or three years when capacity drops quickly, but charger malfunctions also occur frequently—such as loose interfaces or damaged internal components. Wiring issues like broken or corroded wires can also cause charging failure. In terms of handling, I first tried another charger, and if that didn't work, I checked if the battery terminals were dirty, using a multimeter to measure voltage for confirmation. I suggest not rushing to replace the battery; troubleshooting simple components can save money. The normal lifespan of a battery is 2-3 years, and regular shallow discharge and charging can extend its usage. Address issues early to avoid being stranded on the road.
