The invention relates to a charging pile switching system and a charging pile switching system control method. The system comprises a power supply cabinet and N charging terminals. The power supply cabinet comprises a switching matrix and an AC input unit. The switching matrix comprises M first type switching modules, M second type switching modules and K direct current contactor groups; the M first-type switching modules are connected end to end to form a first annular switching loop, and a direct current contactor group is connected between every two adjacent first-type switching modules; the M second-type switching modules are connected end to end to form a second annular switching loop, and a direct current contactor group is connected between every two adjacent second-type switching modules; and the first type of switching modules are connected with the second type of switching modules in a one-to-one correspondence manner. Due to the structure of the switching matrix, combined switching of the switching modules can be carried out according to the required power of the electric equipment, for example, all the switching modules can be switched to one switching module for output, and the utilization rate of the switching modules is improved to 100%.
本申请涉及一种充电堆投切系统和充电堆投切系统控制方法。系统包括电源柜以及N个充电终端;电源柜包括投切矩阵和交流输入单元;投切矩阵包括M个第一类投切模块、M个第二类投切模块以及K个直流接触器组;M个第一类投切模块首尾相连形成第一环形投切回路,且各相邻的第一类投切模块之间连接有直流接触器组;M个第二类投切模块首尾相连形成第二环形投切回路,且各相邻的第二类投切模块之间连接有直流接触器组;第一类投切模块与第二类投切模块一一对应连接。由于本申请的投切矩阵的结构,使得可以根据用电设备的需求功率进行投切模块的组合投切,例如可将所有的投切模块投切到一个投切模块进行输出,将投切模块的使用率提高到了百分之百。
