Why is the electric vehicle charger flashing green light?
3 Answers
If the electric vehicle charger is flashing a green light, it may indicate a circuit disconnection. A steady green light usually signifies that the battery is fully charged. However, if the battery is depleted and the charger still shows a green light upon connection, it could imply a circuit disconnection. Here are the solutions for troubleshooting a flashing green light on an electric vehicle charger: Check the charger output line: Inspect whether the charger output line is broken. You can use a multimeter to verify if there is any electrical output. Check the battery connection line: Examine the battery connection lines for any breaks. A multimeter can be used to test the circuit continuity. Replace the battery: If the electric vehicle battery has been in use for over a year, it might be damaged and require replacement. Visit an electric vehicle repair shop for professional inspection and servicing.
My electric car had the green light flashing a while ago, which is quite common. Generally speaking, a flashing green light indicates that the charger is working normally, but continuous flashing may indicate an issue. Common reasons include the charging nearing completion and entering trickle charging mode, where the battery requires maintenance current; it could also be due to poor heat dissipation in the charger causing overheating and triggering a flashing warning; or it might be caused by loose connections or dust in the interface affecting contact. When I dealt with it last time, I first checked if the connection between the charger and the socket was secure, then cleaned the interface of dust and restarted it. If it still flashes, it might be due to an internal circuit fault or battery aging. It's advisable not to charge for long periods with the light flashing, as it can easily damage the components. If possible, check the charger's manual or visit a repair shop for inspection—safety first.
As someone who frequently tinkers with electric vehicles, I have some insights about the flashing green light. This usually indicates the charger is sending status signals: either the charging is nearing completion with a small current top-up, or it's an alarm for issues like overheating or a short circuit. You can troubleshoot it yourself first: check if the charging cable and socket are functioning properly, clean the charging port to avoid oxidation; observe if the battery is too hot or deformed; if it flashes rapidly, it might be due to damaged internal components in the charger or battery issues. Sometimes unstable voltage can also cause this, especially when using old sockets. Don't rush to replace it; try restarting the entire system or switching to a different charging point to see if the flashing persists. If all else fails, take it to a professional for repair to prevent component damage that could affect battery lifespan.
