Charging Point
The function of the charging pile is similar to that of the fuel dispenser in the 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 parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels.
The input end of the charging pile is directly connected with the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle. According to the charging mode, it can be divided into AC charging pile, DC charging pile and wireless charging. According to time, it can also be divided into fast charging, slow charging and power change.
Electric vehicle refers to a vehicle that is powered by on-board power supply and driven by motor to drive the wheels, and meets the requirements of road traffic and safety regulations.
It uses electricity stored in the battery to start. The storage battery must be charged by a charging device. Electric vehicle charging facilities are an important part of the electric vehicle industry chain. At present, the charging facilities for electric vehicles are mainly charging stations and charging station piles.
The charging station can be divided into four sub modules according to its functions: power distribution system, charging system, battery dispatching system and charging station monitoring system. The core of the charging system is also the charging pile.
As can be seen from the above figure, the endurance capacity of most electric vehicles is only more than 100 kilometers, so the endurance mileage has become the biggest obstacle encountered in the development of new energy electric vehicles. To ensure the normal driving of electric vehicles, it is necessary to build enough charging stations to facilitate people to charge when driving electric vehicles. "The army has not moved, and the food and grass have taken the lead", and giving priority to the construction of charging stations is a prerequisite for the development of new energy vehicles. This relationship cannot be reversed.
