If the charger makes no sound, it could be due to a damaged charger or the charger not being a forced-air cooling type. Here are the relevant details: 1. Damaged charger: When you plug in the charger to charge the electric vehicle, if even the power indicator light doesn't turn on (assuming the input power supply is functioning properly), you should consider that the charger might be damaged, and naturally, it wouldn't produce any sound. 2. Forced-air cooling charger: Most electric vehicle chargers nowadays use switching power supplies, which operate silently. To forcibly cool the switching power supply's power transistors, many charger manufacturers install fans inside the charger. If the charger doesn't have forced-air cooling, the absence of sound is a normal phenomenon.
