Working principle of energy storage charging pile

The working principle of energy storage charging pile mainly includes three processes: charging, energy storage and discharging. When an electric vehicle is connected to the energy storage charging pile, the charging pile will convert the grid power into DC power and transmit the power to the battery of the electric vehicle through the charging interface for charging. When the grid power supply is excessive or the electric vehicle does not need to be charged, the energy storage charging pile will store the excess power, usually in a built-in energy storage system such as a battery pack or supercapacitor. When the electric vehicle needs power, the energy storage charging pile will release the stored power and transmit it to the battery of the electric vehicle through the charging interface for the electric vehicle to use.
