第一DC/DC 500，用于对第一储能电池200的输出进行直流变换，其中DC/DC是指直流到直流的变换器；
第二DC/DC 600，用于对第一储能电池300的输出进行直流变换；以及
电机驱动器700，用于将动力电池400输出的直流电压变成驱动电机的电压。
进一步，在图1的电动型移动充电车的电路构造中还具备下述开关：
第四开关K4，设置在第一储能电池200和第一DC/DC500之间；
第五开关K5，设置在第二储能电池300和第二DC/DC600之间；
第六开关K6，设置在动力电池400和电机驱动器700之间；
第七开关K7，设置在第五开关K5和第六开关K6之间；
第八开关K8，设置在第一DC/DC500的输出端(即第一DC/DC500一端与第四开关K4连接，第一DC/DC500的另一端与第八开关K8)；
第九开关K9，设置在第二DC/DC600的输出端(即第二DC/DC600一端与第五开关K5连接，第二DC/DC600的另一端与第九开关K9)；以及
第十开关K10，设置在第八开关K8和第九开关K9之间。
在图1所示的电动型移动充电车中，如上所述，选择相同的电池作为第一储能电池200、第二储能电池300以及动力电池400，这样做的好处是：
A.当电动型移动充电车的活动范围较小时，用户分布紧凑对电动型移动充电车本身的续航里程要求低，可利用电动型移动充电车本身的动力电池给用户充电；
B.当电动型移动充电车的活动范围较大时，用户分布较为分散、野外救援的情形等，这时可利用储能电池的电量为充电车充电续航。
另一方面，在图1所示的电动型移动充电车中，当本发明的电动型移动充电车需要补电时，可通过将充电接口100为第一储能电池200、第二储能电池300以及动力电池400进行充电，通过将第一开关K1、第二开关K2以及第三开关K3中的任意一个关闭闭合可以控制充电接口100为哪一块电池充电，其中，在同一时刻第一开关K1、第二开关K2以及第三开关K3中只能有一个开关闭合，每次动作之间要确认所有开关的状态。例如，通过仅闭合第一开关K1，能够从充电接口100对第一储能电池200进行充电；通过仅闭合第二开关K2，能够从充电接口100对第二储能电池300进行充电；通过仅闭合第三开关K3，能够从充电接口100对动力电池400进行充电。
另一方面，对于图1所示的电动型移动充电车，当该电动型充电车为用户充电时：
A.如果两个用户在同一地点，本发明的电动型移动充电车可以同时输出两路直 流电为两个用户充电，这时断开第十开关K10，闭合第四开关K4和第八开关K8输出一路直流电，闭合第五开关K5和第九开关K9输出一路直流电。
B.当只有一个用户需要服务时，在本发明的电动型移动充电车中，闭合第八开关K8和第十开关K10并断开K9；或者闭合第九开关K9、第十开关K10并断开第八开关K8，这样可以利用两路DC/DC系统关联为用户提供更为快速的充电服务。
根据本发明第一实施方式的电动型移动充电车，利用第一开关K1、第二开关K2以及第三开关K3这三个切换开关来实现一次插枪可给三块电池充电，而且在第一实施方式中只需要设置一个充电接口100就能够为各储能电池与动力电池进行补电，有效简化操作流程，简化了电路结构，节省成本。
第二实施方式
接着，对于本发明的第二实施方式的电动型移动充电车进行说明。
图2是表示本发明第二实施方式的电动型移动充电车的一部分的电路的电路构造图。
图2所示的电动型移动充电车的电路构造图是在图1所示的电路构造中增加设置了监控器800。为了简化电路图，在图2中省略了图1中的右侧部分的电路。监控器8000的一端与充电接口100连接，另一端分别连接到第一储能电池200、第二储能电池300以及动力电池400。
参照图2对于对本发明的电动型移动充电车进行补电操作的情形进行说明。所谓补电操是指为电动型移动充电车的储能电池与动力电池充电。在上述图1的电动型移动充电车中通过利用第一开关K1、第二开关K2以及第三开关K3这三个切换开关来实现一次插枪可给三块电池充电，对操作人员来说只需要一次插枪操作，由监控器800根据它的充电决策控制完成。
以下，对于由监控器800控制的补电操作进行具体说明。
监控器800根据第一储能电池200、第二储能电池300以及动力电池400的SOC控制补电操作。具体如下：
A.监控器800获取第一储能电池200、第二储能电池300以及动力电池400这三块电池的SOC，优先对动力电池400进行补电，在给动力电池400进行 补电时第一开关K1、第二开关K2断开，第三开关K3闭合，在给动力电池400补电完成后，第三开关K3断开，这时补电监控自动重启；
B.监控器800再次获取第一储能电池200、第二储能电池300以及动力电池400这三块电池的SOC，这时动力电池400为满电状态，对于储能电池，优先给其中SOC较小的储能电池充电，充电时只有电池对应的开关闭合，其他开关断开，当前电池充电完成，断开当前相应的开关，补电监控自动重启；
C.监控器800再次获取第一储能电池200、第二储能电池300以及动力电池400这三块电池的SOC，这时只有一块电池的SOC较小，则给最后一块电池补电，其开关状态操作与上述类似情况。当充电完成，断开当前开关，补电监控自动重启动；
D.监控器800再次获取第一储能电池200、第二储能电池300以及动力电池400这三块电池的SOC，这时检测到三块电池都是满电状态，这时向操作人员发送充电完毕的消息。
图3是表示本发明第二实施方式的电动型移动充电车的另一部分电路的电路构造图。
接着，参照图3对于本发明第二实施方式的电动型移动充电车的服务操作进行说明。所谓服务操作就是指电动型移动充电车对用户的电动车进行充电服务操作。
在本实施方式中，服务操作分以下几种情况：
(1)同时给两个用户充电的情况下，利用第一储能电池200给用户1充电、利用第二储能电池300给用户2充电，这时第四开关K5、第五开关K5、第八开关K8以及第九开关K9闭合，同时，第十开关K10断开，由此从第一储能电池200通过第一DC/DC500向用户1供给充电，从第二储能电池300通过第二DC/DC600向用户2供给充电为给两个用户充电；
(2)仅给一个用户充电的情况下，可以利用第一储能电池200和第二储能电池300一起为同一用户充电，开关状态为第四开关K4、第五开关K5以及第十开关K10闭合，同时，根据实际插充电枪的情况来选择闭合第八开关K8或者第九开关K9中的一个。另外，在用两块电池同时给一个用户充电时，可优先对第二储能电池300放电。
(3)当充电车活动范围较小时，在第一储能电池200、第二储能电池300都没有电量可用的情况下，还可以利用动力电池300为用户充电。这时需要关闭充电车本身电源，即断开第四开关K4、第五开关K5，闭合第七开关K7，利用动力电池400通过第二DC/DC600为用户充电。
如上所述，根据本发明第二实施方式的电动型移动充电车，能够利用监控器800对各储能电池以及动力电池的SOC进行监控，根据监控结果对储能电池以及动力电池进行补电，其中，优先对动力电池进行补电，在动力电池完成补电的情况下，再优先对SOC相对较小的储能电池进行补电，由此，能够保证优先对动力电池进行补电，能够实现以智能、高效的方式对移动充电车的动力电池和储能电池进行补电。
而且，根据本发明第二实施方式的电动型移动充电车，利用第一储能电池200以及第二储能电池300能够同时给两个用户提供充电，另一方面，也可以利用第一储能电池200以及第二储能电池300一起给同一个用户提供充电。而且，还能够利用动力电池400给用户提供充电，因此，本发明第二实施方式的电动型移动充电车能够按照应用的实际情况提供多种充电方式，充电方式多样，充电效率高。

最后，对于本发明的变形例电动型移动充电车的电路构造进行说明。

若所述第1储能电池～第N储能电池以及所述动力电池的SOC都为满电状态，则补电动作结束。
另一方面，述监控器进一步用于根据监测结果控制电动型移动充电车对用户提供充电服务。具体地，所述监控器设置为实施以下方式之一的控制：
利用第一～第N储能电池分别为N个用户提供充电服务；
