Why is the electric vehicle charger not lighting up?
2 Answers
The reasons why the electric vehicle charger is not lighting up are: 1. The battery and charger do not match: An incompatible charger can cause the power source to generate excessive heat during charging, leading to overheating; 2. Quality issues: Charging an electric vehicle battery requires the release of a large amount of hydrogen gas, but new batteries generally do not exhibit such overheating issues as they are pre-treated by the manufacturer to maintain a constant temperature. If overheating occurs, it indicates a problem with the new battery. The solutions for an electric vehicle charger not lighting up are: 1. Purchase from the original dealer to ensure compatibility; 2. Always follow the manufacturer's instructions strictly during the charging process.
When I first started repairing electric vehicle charging, it was quite common to encounter situations where the charger didn't light up, and the reasons varied widely. The most common issue was a faulty charger itself, such as aging internal components or a short circuit blowing the fuse, causing the indicator light to go out directly. Another frequent problem was power supply issues, like a dead socket or unstable voltage, preventing the charger from functioning. I remember helping a friend fix theirs last time—it turned out the connection wire was loose, and simply plugging it back in tightly solved the problem. But safety comes first; don’t tinker blindly. Use a multimeter to check the voltage or try a different socket. Environmental factors also matter; for example, high temperatures can cause the charger's overheating protection to fail. It's advisable to regularly inspect the charger head and battery port to avoid oxidation and poor contact. If all else fails, take it to a professional shop for testing—after all, electric vehicle charging safety isn’t something to take lightly. Always use reputable brands for easier maintenance.
