Types of Electric Vehicle Charging Piles
By charging mode
- AC charging pile
The AC charging pile, commonly known as "slow charging", is a power supply device that is fixed outside the electric vehicle and connected to the AC power grid to provide AC power for the onboard charger of the electric vehicle. The AC charging pile only provides power output and has no charging function. It is necessary to connect the onboard charger to charge the electric vehicle. It is equivalent to just playing the role of a control power supply.
- DC charging pile
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.
By installation location
- public charging point. A charging pile is built in a public parking lot combined with a car berth to provide charging services for social vehicles.
- Dedicated charging point. The owner's parking lot is a charging pile used by internal personnel of the unit.
- Self-use charging point. It is built in a personal garage to provide charging piles for private users. The above describes different types of charging piles in different ways. Next, we mainly introduce the characteristics of charging piles divided according to charging methods.
