It is a common problem that an electric car charger lights up green but fails to charge the battery. This article will introduce some possible reasons and the corresponding solutions to help you solve this problem.
1. The battery is damaged:
If the internal resistance of the battery is too large, it will lead to a smaller current input during the charging process, and the charger may only show a green light at this time. To solve this problem, you may consider replacing the battery to ensure good current input.
2. Charger failure:
Damage to the filter capacitor or filter resistor inside the charger may be one of the reasons why the charger has a green light and is not charging. Usually, this damage is caused by vibration to the charger. It is easy to solve this problem, just need to replace the damaged parts.
3. power supply false connection:
When the plug is not plugged in properly or the charging cable is bent by an external force, it may lead to a false power connection. At this time, the charger still shows a green light but cannot charge the battery. If the plug is not plugged in, you just need to re-plug the plug to solve the problem; if the charging cable is damaged caused by the false connection, you need to replace the charging cable or ask a professional to repair the barge.
If the above methods are ineffective, it may involve more causes of failure, we suggest you to ask professionals to check and repair to ensure that the electric car can be charged and used normally.
