What Causes the Noise When Charging a Car?
2 Answers
Car charging noise reasons are as follows: Charging current sound: The sound generated by electric current during charging. Transformer operating sound: The noise produced when the transformer is working. Fan operation sound: The sound generated by the fan inside the charger. All the above noises are normal phenomena and will not affect product usage. Car charging precautions are as follows: Check electrolyte: For batteries in cold weather, check if the electrolyte is frozen before charging. Never charge a frozen battery as it may cause explosion. Check electrolyte level: Before charging, check the electrolyte level. Do not charge if the electrolyte is insufficient.
Hey, I've experienced noise issues when charging my electric car before. At first, the buzzing sound made me think the car was about to explode, but later I learned it was just the battery heating up during charging, and the fan automatically turning on for cooling – which is perfectly normal. However, if the noise turns into a clicking or sharp hissing sound, you should be cautious. It might be caused by a loose charging gun or a loose wire connection leading to a short circuit. A friend of mine once burned out their charger by ignoring this. I recommend checking that the cable is intact before each charge, ensuring there's no water or moisture around, and not rushing to unplug the gun after charging – wait until the fan stops. Regular maintenance for your car can also prevent problems before they occur. Don't wait until a major issue arises to rush to the 4S shop. Safety always comes first.
