Is the non-motor vehicle charging pile noisy and safe?

1, the input power supply of electric vehicle is alternating current, and the output is direct current. Manufacturers use high-frequency switching rectifier technology to convert alternating current into direct current. The greater the power, the louder the sound, which is inevitable.

2. With the increasing use and frequency of charging piles for battery cars, charging piles for battery cars have become a charging tool used by many residents every day, so charging piles will undergo strict inspection before leaving the factory to check whether the products are in good condition, which also eliminates the problems in the use of charging piles. Secondly, the charging pile of the battery car is designed during the research and development and production, and there are safety protection measures, so the safety is higher.
