The DC charging pile, commonly known as "fast charging", is a power supply device that is fixed outside the electric vehicle and connected with the AC power grid, and can provide DC power for the power battery of the off-board electric vehicle. Direct current can be directly output to charge the battery of electric vehicles. The output voltage and current can be adjusted in a wide range to provide sufficient power to realize the rapid charging of electric vehicles. The DC charging pile has a fast charging speed, so it is generally installed in the charging station beside the expressway.

 

  • AC / DC integrated charging pile

 

The fast-charging pile equipment adopts the AC / DC integrated structure. Both DC and AC charging can be realized. When there are many charging services in the daytime, DC mode is used for fast charging. When there are few users in the charging station at night, AC charging can be used for slow charging. The touch screen and keyboard shall be controlled by mutual backup, and the touch screen and keyboard shall be designed to prevent rain and dust; Emergency stop switch with emergency stop; There is a charging connector placement slot, which can be waterproof.
