储能堆供电充电桩的研究
Research on Power Supply Charging Pile of Energy Storage Stack

储能式充电桩是指在传统的充电桩箱内，按需要添加不同容量的储能电池。由于在使用充电桩进行充电过程中才能获取所需参数，用于计算其储能结构的剩余电量，且多个充电桩同时使用将会会影响单元用电量，存在浪费时间等待后而充电桩单元却无法满足充电需求，为正常使用带来了困扰。本文提出了一种用于充电桩的储能堆供电系统，其目的在于优化充电桩储能结构的使用管理，增大足额单元电量的充电桩使用数量。相比现有技术，本设计将储能结构本身作为可电量监测的辅助单元，简化了电量监控单元的设计，以实际测量为准，并进而计算得出最大充电桩数量。该设计既方便充电用户掌握相关信息，也方便管理人员合理调度﹑管理充电设备以及有充电需求的客户。
Energy storage charging pile refers to the energy storage battery of different capacities added according to the practical need in the traditional charging pile box. Because the required parameters can only be obtained during the process of charging piles, then it is used to calculate the remaining power of the energy storage structure. Multiple charging piles at the same time will affect the electricity consumption of the unit. It will waste time and if at last the charging pile unit cannot meet the charging demand, which brings trouble to the normal use. This paper proposes an energy storage pile power supply system for charging pile, which aims to optimize the use and management of the energy storage structure of charging pile and increase the number of charging pile with full unit power. Compared with the existing technology, this design takes the energy storage structure as an auxiliary unit for power monitoring, simplifies the design of the power monitoring unit, and then calculates the maximum number of charging piles using the actual measurement. The design not only facilitates the charging users to grasp the relevant information, but also facilitates the management personnel to reasonably dispatch and manage the charging equipment and the customers with charging needs.
