The invention discloses a flexible direct current charging system dynamically distributed along with transformer capacity in the field of direct current charging, which comprises a split type charging pile host, a residual capacity monitoring module, a charging module and a charging terminal, and is characterized in that the split type charging pile host is composed of a power conversion main loop and a control system. The residual capacity monitoring module is used for recording the operation state of the transformer, data is transmitted to the background system through 4G network transmission, the background system can predict the use capacity change state of the transformer through big data analysis, more reasonable resource allocation can be carried out, the effective high power capacity and the utilization rate of power equipment are improved. Through reasonable configuration, the charging requirement of a user is met to the greatest extent, the control process is simple, the number of switching devices is small, the maintenance process is simple, the residual capacity of the transformer and the voltage and current power of real-time operation of the transformer are detected in real time, and the system safety level is high.

    本发明公开了直流充电领域的一种随变压器容量动态分配的柔性直流充电系统,包括分体式充电桩主机、剩余容量监控模块、充电模块和充电终端,所述分体式充电桩主机由功率转换主回路和控制系统组成。本发明利用剩余容量监控模块记录变压器运行状态,通过4G网络传输,把数据传到后台系统,后台系统可以通过大数据分析,预测变压器使用容量变化状态,可以进行更合理的资源配置,提有效的高电力容量和电力设备的利用率,通过合理的配置,最大可能的满足用户的充电需求,控制过程简单,且开关器件较少,维修维护过程简单,通过对变压器剩余容量、变压器实时运行的电压电流功率进行实时的检测,系统安全等级高。
