The function of charging pile is similar to that of the tanker in the gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lot or charging station. 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 network, and the output end is equipped with a charging plug for charging the electric vehicle. Charging piles generally provide two charging modes: conventional charging and fast charging. People can use specific charging cards to swipe cards on the interface of man-machine interaction provided by charging piles, and carry out corresponding charging modes, charging time, cost data printing, etc. Charging piles display screen can display charging amount, charge and charge. Time and other data.
Up to now, the charging stations of electric vehicles in China are mostly confined to electric buses or internal group vehicles, and the service network of charging stations for different users has not yet been built. The representative charging stations that have been built or are under construction have the following contents. In 2006, BYD built Shenzhen's first electric vehicle charging station at its headquarters in Shenzhen.
In 2008, the first centralized charging station in China was built during the Beijing Olympic Games, which can meet the power battery charging demand of 50 pure electric buses.
In October 2009, Shanghai Electric Power Company invested in the construction of Shanghai Caoxi Electric Vehicle Charging Station, which is the first commercial electric vehicle charging station in China. At the end of 2009, Beijing Shouke Group completed the first demonstration charging station for Beijing pure electric passenger cars in Jianxiangqiao, which includes a complete smart micro-grid.
On December 31, 2009, the first batch of charging stations (piles) for electric vehicles put into operation in Southern China Power Grid were built and put into operation in Shenzhen, with a construction scale of 2 charging stations and 134 charging piles (bolts).
On March 31, 2010, Tangshan Nanhu Charging Station of State Grid Corporation was built and put into operation. It is the first typical design charging station of State Grid in China. It can charge 10 electric vehicles in two ways: fast charging and slow charging.
