下面参照附图来描述本发明的优选实施方式。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。
本发明提出了一种多支路多端口的储能型移动充电车充电系统，包括由载能电池及充电机构成的电动车充电单元，所述电动车充电单元的数量为两个或两个以上；各电动车充电单元的充电机输出端的连接呈拓扑结构，该结构中相互连接的两个充电机输出端之间设置有开关电路。
拓扑结构中点与点间的连通关系是可以通过边传递的，也就是说连通关系是具有传递性的，在本发明中各电动车充电单元的充电机输出端的连接呈拓扑结构，每个充电机输出端为一个点，两个点之间的具有开关电路的电连接线路为边，通过拓扑结构中相邻的点之间的电连接线路中开关电路的闭合实现多个充电机输出端之间的直流并联大功率输出。
本发明中的所采用的拓扑结构可以为总线型拓扑、环形拓扑、树形拓扑、星形拓扑、混合型拓扑以及网状拓扑等等，只要能实现多个充电机输出端之间的直流并联大功率输出即可。
以6个电动车充电单元为例，将其对应的6个充电机的输出端在C1～C6分别以小圆表示，开关为K1～K6，则对应的环形拓扑结构如图1所示，总线型拓扑结构如图2所示。
本发明在使用状态下，可以依据电动车(待充电车辆)的充电功率参数，闭合相应数量的开关电路，使相应数量的充电机输出端连通后直流并联输出对电动车充电。
本发明中各载能电池分别设置有独立的充电口，充电机构分别设置有独立的充电枪。
本发明中开关电路可以为手动开关。
进一步的，还包括充电机控制器；所述充电机控制器过通信线路分别与各充电机相连接，用于获取电动车动力电池的电池参数，并控制相应充电机对电动车充电。
本发明中开关电路还可以为电磁继电器，电磁继电器的控制端与充电机控制器相连接。
进一步的，还包括整车控制器；每一个载能电池配置一个电池管理系统；所述整车控制器通过通信线路分别与充电机控制器、各电池管理系统相连接，用于获取充电机控制器、各电池管理系统的检测数据，以及向充电机控制器发送控制信息。
本发明中整车控制器与充电机控制器、各电池管理系统相连接的通信线路为CAN总线。
进一步的，还包括交互单元；所述交互单元与整车控制器过通信线路连接，用于显示整车控制器所获取的检测数据、以及向整车控制器发送控制信息。
本发明中交互单元与整车控制器之间的通信线路为RS485总线。
本发明还提出了一种移动充电车，包括车体、以及上述多支路多端口的储能型移动充电车充电系统。
下面以两个电动车充电单元为例对本发明的多支路多端口的储能型移动充电车充电系统进行详细说明。
本实施例的多端口的储能型移动充电车充电系统如图3所示，可以分为三层结构：顶层-人机交互层、中层-集中控制层、底层-设备控制层。
顶层设备为交互单元HMI；中层设备为整车控制器VCU、充电机控制器CMU；底层设备输入侧为第一载能电池和第二载能电池分别配套第一电池管理系统BMS-1和第二电池管理系统BMS-2，输出侧为第一充电机和第二充电机；第一载能电池和第二载能电池分别设置有独立的充电口，第一充电机和第二充电机分别设置有独立的充电枪。
交互单元HMI负责人机对话，接收操作者下发的指令，并将指令下发至中层；整车控制器VCU接收HMI的指令并根据底层上传的信息综合判断后下发指令至电池管理系统或充电机控制器CMU进行控制；底层设备接收中层设备的指令并根据内外部设备的信息进行控制保护，并及时将信息上送至中层设备；各层设备之间自上而下进行控制且下层具备一定的独立性，即下一层受控于上一层控制，但在上一层出现故障后，下层可保持故障前所接收的指令独立正常运行。
交互单元HMI和整车控制器VCU之间通过RS485总线进行点对点通信，RS485总线为差分总线，具备较强的抗干扰性；整车控制器VCU具备3路CAN接口，分别连接输入侧的第一电池管理系统BMS-1、第二电池管理系统BMS-2和充电机控制器CMU。
基于输入侧第一载能电池和第二载能电池可从外部充电桩同时或单独进行充电，故整车控制器VCU分别通过CAN-BM1、CAN-BM2连接第一电池管理系统BMS-1和第二电池管理系统BMS-2通信接口，第一载能电池和第二载能电池可独立进行充电工作而互不影响；即第一载能电池和第二载能电池可进行单独充电或双路同时充电，且每一路控制参数可设置为不同值。
基于输出侧第一充电机和第二充电机具备独立输出和直流侧并联输出两种模式，故设置充电机控制器CMU对两路充电机进行统一控制和管理，整车控制器VCU和充电机控制器CMU之间通过CAN-C总线进行通信，充电机控制器CMU根据整车控制器VCU下发的工作模式及参数进行操作控制或下发参数值至底层第一充电机和第二充电机；通过一路CAN-C总线控制两台充电机，确保控制、保护的在逻辑及时间轴的一致性。
外部第一充电桩通过CAN-BC1连接至第一载能电池及第一电池管理系统BMS-1，外部第二充电桩通过CAN-BC2连接至第二载能电池及第二电池管理系统BMS-2，两路通信及控制相互隔离，互不影响，可实现两路的独立或同时充电工作。
外部第一电动车电气接线连接至第一充电机，其通信接口通过CAN-EV1直接连接至充电机控制器CMU；外部第二电动车电气接线连接至第二充电机，其通信接口通过CAN-EV2直接连接至充电机控制器CMU；充电机控制器CMU根据实际情况接收第一电动车、第二电动车 上传的电池信息，并根据整车控制器VCU下发的工作模式和参数控制第一充电机、第二充电机输出；当需要单台大功率输出时，CMU控制开关K闭合，第一充电机、第二充电机输出侧并联给一台电动车充电；当需要单台或两台小功率输出时，CMU控制开关K分断，第一充电机、第二充电机分别输出给对应电动车充电。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
