Talk about the concept of car charging pile scheme

Introduction to charging pile

The function of the charging pile is similar to the refueling machine in a gas station. It can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential community parking lots or charging stations. It can be based on different voltage levels. Charge various types of electric vehicles. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging electric vehicles.

Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging methods, charging time, and cost data printing. The charging pile display can display data such as charging capacity, cost, and charging time.

　　 Charging post (bolt) can realize time, electricity meter, and amount of charging, and can be used as a citizen's electricity purchase terminal. At the same time, in order to improve the efficiency and practicability of public charging piles (bolts), the functions of a pile (bolt) for multiple charging and electric bicycle charging will be added in the future.

　　 Types of charging piles

　　 There are four types of charging piles:

　　 1. According to the installation method. It can be divided into floor-mounted charging piles and wall-mounted charging piles. Floor-standing charging piles are suitable for installation in parking spaces that are not close to the wall. Wall-mounted charging piles are suitable for installation in parking spaces close to the wall.

　　 2. According to the installation location. According to the installation location, it can be divided into public charging piles and special charging piles. Public charging piles are built in public parking lots (garages) combined with parking spaces to provide public charging services for social vehicles. The special charging pile is the self-owned parking lot (garage) of the construction unit (enterprise) and is used by the internal personnel of the unit (enterprise). Self-use charging piles are built in personal parking spaces (garages) to provide charging for private users. Charging piles are generally constructed in conjunction with parking spaces in parking lots (garages). The protection level of charging piles installed outdoors should not be lower than IP54. The protection level of charging piles installed indoors should not be lower than IP32.

　　 Three, according to the number of charging ports. It can be divided into one charge and one charge.

　　Four. According to the charging method. Charging piles (bolts) can be divided into DC charging piles (bolts), AC charging piles (bolts) and AC and DC integrated charging piles (bolts).

　　 Technical realization of charging pile

　　As an energy replenishment device for electric vehicles, the charging performance of the electric vehicle charging pile is related to the service life and charging time of the battery pack. This is also one of the aspects that consumers are most concerned about before buying an electric car. Achieving fast, efficient, safe, and reasonable power replenishment for power batteries is the basic principle of electric vehicle charger design. In addition, the applicability of the charger to various power batteries must be considered.
