本发明具有如下有益效果：本发明是在纯电动车的基础上加了一套充电系统，构成了移动充电车，即可移动的充电桩，随时随地的给任意一个纯电动车应急充电。
附图说明：
图1为本发明原理框图。
图2为整车系统框图。
图3为低压上下电原理。
图4充电系统高压上电流程。
图5充电系统高压下电流程。
具体实施方式：
下面结合附图对本发明作进一步的说明。
如图1至图5，本发明一种移动充电车充电策略，包括动力电池、高压配电柜、充电机和储能能量管理系统，所述动力电池和高压配电柜对应与储能能量管理系统相连，动力电池与充电机均对应与高压配电柜相连。
动力电池选用105AH电芯。高压配电柜的功率为360KW。
移动充电车是由能源系统(驱动)、辅助系统、电力驱动系统级充电系统组成。除去充电系统以外，这个车子与其他的纯电动车无明显区别。该车是在纯电动车的基础上加了一套充电系统，构成了移动充电车，即可移动的充电桩，随时随地的给任意一个纯电动车应急充电。整车系统框图如图2所示(注：动力电池(驱动)：指给车辆本身行驶用的动力电池。动力电池(储能)：指给其他车辆以及车辆本身充电的动力电池)。
本发明中动力电池的高压电到高压配电柜，高压配电柜根据具体情况把高压电分配给充电机，充电机实现给其他车辆或者本车驱动电池充电。
低压上下电流程及控制逻辑
储能电池管理系统(BMS)及高压配电柜低压电使用常电，充电机的低压电源用仪表台上面的翘板开关控制。需要使用充电机充电时，打开整车低压闸刀开关，BMS得电开始进行通讯，此时按下仪表台上的翘板开关，充电机得电开始进行通讯，通讯完成之后，储能电池本身没有在充电，且无故障，执行相应的高压上电流程。下低压电，只需要将翘板开关关闭，再断开低压闸刀开关即可。
BMS及高压配电柜使用常电的原因是储能电池的BMS要实时的与整车进行通讯，让整车控制器掌握储能电池的健康状况，并且将储能电池的故障信息、电压、SOC、单体信息等在仪表显示，让驾驶员实时掌握电池的状态。
高压上电流程：BMS自检成功，收到车载充电机插枪报文(充电机的充电枪接在被充电车上)，高压配电柜内的放电继电器无粘黏故障，依次吸合放电继电器，完成高压上电(如图4)。
高压下电流程：充电机无插枪信号，且车载充电机无需求电流。BMS切断放电回路，完成高压下电。车载充电机故障，BMS发BMS强制切断高压，充电机在10s内至少将电流降至0A，如10s后电流仍大于0A，BMS此处先上报强制切断指令告诉充电机，1s后，自行切断高压。如图5所示。
低压电瓶防亏电控制逻辑：因为充电系统用的低压电为整车低压小电瓶，储能电池BMS及车载充电机长时间使用低压小电瓶。因为充电系统工作时，整车驱动系统没上高压电，低压小电瓶无法充电。所以储能电池BMS检测低压电瓶电压，当低压小电瓶电压过低时，储能电池BMS断开放电回路，同时向仪表发送低压小电瓶亏电故障，提醒驾驶员上整车高压，给低压小电瓶充电。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下还可以作出若干改进，这些改进也应视为本发明的保护范围。
