How does electric vehicle charging station work?

In recent years, the development of new energy vehicles has become increasingly rapid, and the main factors limiting the development of new energy electric vehicles are the range and charging problems. The range has to be solved by improving the performance of the battery, while the charging problem has to be solved by the popularity of charging piles.

Charging piles are a kind of equipment for charging electric vehicles, divided into AC charging piles and DC charging piles, which are called slow charging and fast charging. The AC charging post is simply a direct connection of 220V electricity from the grid to the electric car, like a household air-conditioning socket can fully meet the requirements. The slightly more complex ones add some control switches and human-machine interface processing on top of this. The charging can be controlled, including the charging time, the charging volume and measures such as on-stop and protection. So AC charging is the same voltage as home electricity only the charging current needs to be larger and the wires need to be slightly thicker. When the AC charging post is connected to an electric vehicle, the AC power is changed to DC power to charge the battery on the vehicle by means of on-board rectification equipment.

The DC charging post simply means that the charging voltage is DC. The DC charging post takes power from the grid, and the charging post itself has an inverter to change the AC power into DC power, which is then directly connected to the battery ends of the electric vehicle. To prevent factors such as overcharging or uneven charging of the battery, a Battery Management System (BMS) is connected to both ends of the battery, which is the core technology of DC charging and can be said to be the battery housekeeper, preventing many unsafe factors and improving the performance and life of the battery.

The DC charging pile adds a lot of safety detection and control, which greatly improves the safety of charging. As the DC charging post adds DC power directly to both ends of the battery, the charging current can be set very high, so the charging time can be greatly reduced.

AC charging posts can be small and convenient, do not require much complexity, can be installed in places such as garages or charging stations and take up very little area. DC charging posts, on the other hand, are very large and generally the equipment is fixed in places such as charging stations, which take up a larger area and the price of the equipment can be much higher.
