Brief description of lithium battery charging pile

The origin of lithium battery charging piles: More and more people are starting to buy and use electric vehicles. Their straight energy supply is to charge them, and the charging piles came into being. Its function is similar to the refueling machine in the gas station, but charging Pile installation is more convenient, as long as the environment permits, it can be installed in various places, such as buildings, squares, parking lots, private houses, communities, etc. The charging pile has two modes, one is fast charging and the other is regular charging. People can choose the corresponding charging method according to their needs. The charging pile can also perform operations such as cost data printing, and the charging pile can display data such as the car's charging amount, cost, and charging time. On September 19, 2015, the 3 series of national standards of GB/T20234 'Connecting Device for Conductive Charging of Electric Vehicles' passed the expert review of the Electric Vehicle Sub-committee of the National Automotive Standardization Technical Committee, marking that my country's charging interface standard revision work has achieved critical progress. The charging interface and communication protocol are the basic standards to ensure the interconnection between electric vehicles and the charging infrastructure. The charging interface standard is under the jurisdiction of the automotive industry, including general requirements, AC charging interface, and DC charging interface. The communication protocol standard consists of electric power Industry centralized. Since the publication of the four standards at the end of 2011, they have played an important role in regulating and guiding the design and processing of electric vehicles and the construction and operation of charging infrastructure. Due to insufficient use experience and data accumulation at the beginning of the standard formulation, some clauses and technical details of the charging interface and communication protocol standards are not detailed enough, and there are still incomplete compatibility problems between different vehicles and charging facilities during use. In 2014, the National Standards Committee officially issued a standard revision plan. The automobile industry and the power industry have collaborated and conducted many discussions and experimental verifications. This revision of the charging interface standard includes: increasing the voltage and current levels, thereby increasing the charging power; adjusting the size of the signal pin and the mechanical lock, optimizing the connection sequence, clarifying the relevant requirements of the electronic lock, and improving the safety of charging .
