[0002] As the construction and popularization of charging piles accelerates, the impact on the power grid is getting higher and higher, especially for fast charging piles. The local charging peak power that the power grid needs to provide may exceed 1MW (megawatt). Such an impact may cause the power grid to collapse, and the charging load is pulsed. The cost of large-scale transformation of the power grid load capacity to meet the fast charging demand is too high. When building charging piles, matching energy storage structures is an effective solution to solve the impact of charging pile loads on the power grid. The use of energy storage structures can effectively avoid the impact of charging on the power grid by adjusting the power peak.

[0003] Among energy storage structures, electrochemical energy storage systems represented by lithium batteries are developing the fastest. The battery energy storage structure consists of two main parts: the power conversion system can perform AC / DC and DC / AC conversion, and the electrical energy enters the battery to charge the battery, or the energy stored in the battery is converted into AC power and transmitted back to the grid. The appropriate power device solution depends on the supported voltage and power flow conditions; the battery management system has battery charging, balancing and health monitoring functions, and is equipped with a microprocessor responsible for system control and communication. The basic components provided by the system can integrate the energy storage structure into a larger system.
