The classification of electric vehicle charging pile is the most common in terms of installation location and charging mode. It can be divided into public piles, special piles and private piles according to the installation location; According to different charging methods, it can be divided into: slow charging (AC charging), fast charging (DC charging), battery replacement (power change) and wireless charging.

DC charging pile: DC electric vehicle charging station, commonly known as "fast charging", is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid to provide DC power for the power battery of off board electric vehicles The input voltage of the DC charging pile is three-phase four wire AC380V ± 15%, the frequency is 50Hz, and the output is adjustable DC to directly charge the power battery of the electric vehicle. As the DC charging pile adopts three-phase four wire system for power supply, it can provide sufficient power, and the output voltage and current can be adjusted in a large range to meet the requirements of rapid charging.

AC charging pile: AC electric vehicle charging pile, commonly known as "slow charging", is fixed outside the electric vehicle and connected to the AC power grid to provide AC power for the on-board charger (i.e. charging pile) of the electric vehicle. Charger fixed on electric vehicle) power supply device. The AC charging pile only provides power output and has no charging function. It needs to be connected to an on-board charger to charge the electric vehicle. It is equivalent to only controlling the power supply.
