The reason for the continuous flashing of the green light after plugging in the electric car charger is that the circuit is not connected. Here are the specific details: Battery Maintenance: Add 15ML of pure water to the battery, charge it with a 4-amp current until the current drops to 1 amp, let it sit for 2 hours, and measure the voltage of each battery to be 13.3. If any battery does not meet this requirement, charge that battery again until it reaches the standard. Then connect the batteries in series. When the battery level is found to be below about 30% during use, it should be charged promptly. Precautions: It is best to charge the battery in a cool, ventilated, and dry place. Direct sunlight or rain can adversely affect the performance of the battery and charger. During charging, keep the battery and charger away from other heat sources. After the battery is used up, it should be fully charged promptly. A green light on the charger indicates a full charge. Storing the battery with insufficient charge for a long time or using the battery without fully charging it will affect its performance. Using the battery 3 hours after the charger shows a green light yields the best results.
I noticed that when the electric car charger's green light is flashing, it usually indicates an issue with the charging process. The most common problems are an unsecured charging plug or dust in the port affecting contact. Once, when I was charging, the green light flashed for half an hour, and I later discovered that the car's charging port was a bit dirty—after cleaning it, everything returned to normal. Additionally, fluctuations in grid voltage can also cause the light to flash, such as when the home circuit is unstable, triggering the charger's self-protection mode. Battery aging is another factor; after long-term use, the battery capacity decreases, making it difficult for the charger to synchronize, so it flashes to indicate a need for inspection. I recommend first trying to reconnect the plug and cleaning the interface. If the green light still doesn’t stay steady, it’s best to take the car to a dealership for a battery test. After all, prolonged charging issues can affect driving safety, and regular maintenance can prevent many problems.
I just started driving an electric car and also encountered the situation where the charger's green light was flashing. A friend said it might be the system detecting something or issuing a warning. It could be due to a poor charging cable connection—sometimes the plug is loose or bent, causing issues. Another reason could be the charger's own overheating protection, especially in summer when garage temperatures are high, requiring it to cool down before trying again. If the battery is nearly full but hasn't stopped charging, the green light might flash as a reminder. I've dealt with similar issues before, and simply restarting the charger or trying a different socket usually solves the problem in most cases. If ignored for a long time, it might damage components, so don't underestimate this signal. If you see the light flashing, unplug it immediately to check if the charging cable is intact, and clean the connectors regularly to prevent oxidation.
