Charging piles can be divided into AC charging piles and DC charging piles according to the charging method.

AC charging pile: AC electric vehicle charging pile, usually called slow charging, is fixedly installed outside the electric vehicle and connected to the AC power grid to provide AC power for the electric vehicle on-board charger (that is, the charger fixedly installed on the electric vehicle) power supply unit. The AC charging pile only provides power output and has no charging function. It needs to be connected to the car charger to charge the electric vehicle. This is equivalent to controlling the power supply.

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. Since the DC charging pile adopts three-phase four-wire power supply, it can provide sufficient power, and the output voltage and current adjustment range is large, which can meet the requirements of fast charging.

In order to meet the needs of different charging piles for energy meters, IVY METERING has developed AC DC Energy Meter respectively.

Bi-directional charging is when your car battery is able to receive energy from the grid and be able to share the power it produces. Bi-directional charging can also make the entire grid greener and more efficient, enabling more and better use of wind and solar energy. There are two main categories: Vehicle-to-Grid (V2G): Energy is exported from the EV charger to support the grid. Vehicle-to-Home (V2H): Energy is used to power a home or business. When you charge an electric vehicle, the alternating current (AC) it receives from the grid needs to be converted to direct current (DC) to make it the correct format to power the car's battery. This can be done with a converter in the car or with an external charger. If you want to use the energy stored in your EV battery to power your home or send it back to the grid, you must convert the DC power from the car back to AC. This is done by bi-directional chargers.
