Description

充电系统和共享系统 技术领域
本申请涉及新能源技术领域，并且更具体地，涉及新能源技术领域中的一种充电系统和共享系统。
背景技术
随着科技的发展，终端(如电动汽车(electric vehicle，EV))的充电功率需求越来越大。电动汽车通常通过充电系统(例如充电桩)进行充电。由于不同电动汽车所需的充电电压差异较大，单个充电系统不能同时为不同电动汽车充电。而且单个充电系统的输出功率难以满足电动汽车的大功率充电需求，影响电动汽车的充电速度。或者，单个充电系统的输出功率远远超过电动汽车的大功率快速充电需求，导致充电系统中功率模块空置。因此，亟需一种可以同时为不同电动汽车充电的技术方案。
发明内容
本申请提供一种充电系统和共享系统，不仅能够同时为不同电动汽车充电，而且在为不同电动汽车充电的过程中，还可以实现不同充电系统之间的功率共享。
第一方面，本申请提供一种充电系统，可以包括多个功率模块、分配开关模块和多个充电端口。其中，分配开关模块可以包括第一分配单元和第二分配单元。
多个功率模块中的第一部分功率模块(如多个功率模块中序号为奇数的功率模块)可以通过第一分配单元与多个充电端口中的第一充电端口连接，多个功率模块中的第二部分功率模块(如多个功率模块中序号为偶数的功率模块)可以通过第二分配单元与多个充电端口中的第二充电端口连接。
从上述连接关系可以看出，第一分配单元与第一部分功率模块和第一充电端口对应，第二分配单元与第二部分功率模块和第二充电端口对应。
第一部分功率模块和第二部分功率模块中的每个功率模块可以用于：将来自外部电源的第一功率(可以用P 1表示)进行转换并输出第二功率(可以用P 2表示)。第一分配单元可以用于：将第一部分功率模块中每个功率模块输出的第二功率P 2分配给第一充电端口。
与第一分配单元类似，第二分配单元可以用于：将第二部分功率模块中每个功率模块输出的第二功率P 2分配给第二充电端口。
于是，第一充电端口可以用于：根据第一分配单元分配的功率为第一终端(如第一电动汽车)充电。
与第一充电端口类似，第二充电端口可以用于：根据第二分配单元分配的功率为第二终端(如第二电动汽车)充电。
本申请提供的充电系统通过分配开关模块中的第一分配单元和第二分配单元将来自第一部分功率模块和第二部分功率模块中每个功率模块输出的功率(即第二功率P 2)分配给不同的充电端口(即第一充电端口和第二充电端口)，不仅能够通过不同的充电端口同时为不同的电动汽车(即第一电动汽车和第二电动汽车)充电，而且充电系统的输出功率能够满足不同电动汽车的充电需求，提高了电动汽车的充电速度和充电系统中功率模块的利用率。
需要说明的是，可以通过同一个外部电源为多个功率模块提供第一功率P 1(即通过同一个外部电源为多个功率模块供电)，还可以通过不同的外部电源为多个功率模块提供第一功率P 1。
进一步地，上述的第一功率P 1可以由外部电源的输出电压和输出电流共同确定，上述的第二功率P 2由功率模块的输出电压和输出电流共同确定。
更进一步地，外部电源的输出电压可以为直流电压，也可以为交流电压。
于是，在一示例中，当外部电源的输出电压为直流电压时，上述的功率模块可以为直流(direct current，DC)/DC转换模块。也就是说，功率模块可以将来自外部电源的一种电压等级直流电压进行转换，输出另一种电压等级的直流电压(即功率模块的输出电压可以为直流电压)。
例如，功率模块可以将来自外部电源的高电压等级的直流电压进行转换(如降压)，输出低电压等级的直流电压。
在另一示例中，当外部电源的输出电压为交流电压时，上述的功率模块可以为交流(alternating current，AC)/DC转换模块。也就是说，功率模块可以将来自外部电源的交流电压进行转换(也可以叫做整流)，输出直流电压(即功率模块的输出电压可以为直流电压)。
需要说明的是，功率模块的输出电压的性质(即交流电压或者直流电压)是电动汽车所需的电压性质(即交流电或直流电)决定的。
在一种可能的实现方式中，上述的第一分配单元和第二分配单元均可以包括多个第一切换开关，通过多个第一切换开关实现多个功率模块输出的第二功率分配至不同的充电端 口，实现不同电动汽车的同时充电。
进一步地，分配开关模块还可以包括多个第二切换开关。多个第二切换开关可以将第一部分功率模块和第二部分功率模块中相邻两个功率模块连接。也就是说，本申请可以通过多个第二切换开关实现多个功率模块中相邻两个功率模块之间的互连，并通过相应的第一切换开关将来自功率模块的第二功率分配至相应的充电端口。
例如，多个功率模块中的第一个功率模块和第二个功率模块(两者相邻)之间可以通过一个第二切换开关连接(即第一个功率模块和第二个功率模块之间设置第二切换开关)，多个功率模块中的第三个功率模块和第四个功率模块(两者相邻)之间可以通过另一个第二切换开关连接(即第三个功率模块和第四个功率模块之间设置第二切换开关)。
又例如，第一个功率模块和第二个功率模块(两者相邻)之间可以通过一个第二切换开关连接，第二个功率模块与第三个功率模块(两者相邻)之间不通过第二切换开关连接(也就是说第二个功率模块与第三个功率模块之间不设置第二切换开关)，第三个功率模块与第四个功率模块之间不通过第二切换开关连接(也就是说第三个功率模块与第四个功率模块之间不设置第二切换开关)，第四个功率模块和第五个功率模块(两者相邻)之间可以通过另一个第二切换开关连接。
当然，第二切换开关的布置不局限于以上所列举的情况，只要是相邻的功率模块，都可以通过第二切换开关连接，通过第二切换开关和相应的第一切换开关实现来自功率模块的第二功率传输至相应的充电端口，本申请不做一一列举。
更进一步地，本申请提供的充电系统还可以包括共享开关模块和多个共享端口。其中，多个共享端口可以包括第一共享端口和第二共享端口。
于是，共享开关模块可以将第一部分功率模块与第一共享端口连接，且共享开关模块可以将第二部分功率模块与第二共享端口连接。也就是说，通过共享开关模块实现多个功率模块与多个共享端口的连接。
在一种可能的实现方式中，上述的共享开关模块可以包括第一共享单元和第二共享单元。其中，第一部分功率模块可以通过第一共享单元与第一共享端口连接，第二部分功率模块可以通过第二共享单元与第二共享端口连接。
可选地，第一共享单元和第二共享单元均可以包括多个第三切换开关。
进而，多个功率模块各自输出的第二功率P 2可以通过相应的第三切换开关共享给相应的共享端口，同时，通过控制第三切换开关动作可以灵活控制共享端口传输的功率(即通过共享端口传输给下一充电系统的功率)。
进一步地，上述的共享开关模块除了包括第一共享单元和第二共享单元以外，共享开关模块还包括多个第四切换开关。多个第四切换开关可以将第一充电端口、第二充电端口、 第一共享端口和第二共享端口连接。也就是说，本申请可以通过第四切换开关实现多个充电端口与多个共享端口的互连。
本申请通过在多个充电端口与多个共享端口之间设置多个第四切换开关，并控制第四开关动作，可以实现多个功率模块的输出功率灵活分配至任一充电端口(如第一充电端口或者第二充电端口)或者任一共享端口(如第一共享端口或者第二共享端口)。不仅提高了单个充电端口的充电功率以及单个功率模块的利用率，还通过共享开关模块使充电系统具备对外共享功率的能力，大幅度提升充电系统的灵活性。
在一种可能的实现方式中，上述的第一切换开关、第二切换开关、第三切换开关和第四切换开关分别可以采用接触器、半导体开关(也可以叫做固态开关)或半导体混合开关(可以简称为混合开关)等。
进一步地，上述的接触器可以为单触点接触器(也可以叫做单极接触器)，还可以为双触点接触器(也可以叫做双极接触器)。当然，接触器还可以为其他类型的接触器，本申请实施例对接触器的类型不做限定。
第二方面，本申请提供了一种共享系统，可以包括至少两个(即多个)并联的上述充电系统。
本申请提供的共享系统不仅能够通过不同充电系统的充电端口为不同电动汽车同时充电，且能够实现不同充电系统之间的功率共享,通过功率共享可以大幅度提高了充电系统的输出功率(即充电系统通过充电端口为电动汽车提供的充电功率)。也就是说，功率共享不会影响共享系统为不同电动汽车的同时充电，提高了电动汽车充电的速度和充电系统中功率模块的利用率。
需要说明的是，至少两个充电系统可以通过同一外部电源供电，也可以通过给每个充电系统均配置一个外部电源实现充电系统的独立供电，本申请对至少两个充电系统的供电方式不做限定。
在一种可能的实现方式中，至少两个充电系统之间可以通过功率共享母线连接。
进一步地，功率共享母线上可以设置控制开关或者连接件。
可选地，控制开关可以采用接触器、断路器或者隔离开关等，本申请对此不做限定。
可选地，连接件可以采用连接器或者可拆卸铜排等，本申请对此不作限定。
当然，本申请还可以在功率共享母线上设置其他具有能够实现通断功能的设备，本申请实施例对此不作限定。
更进一步地，功率共享母线可以为铜排、铝排或者线缆等，本申请对此不做限定。
应当理解的是，本申请的第二方面与本申请的第一方面的技术方案一致，各方面及对应的可行实施方式所取得的有益效果相似，不再赘述。

为了解决上述技术问题，本申请实施例提供了一种充电系统，如图1所示。充电系统(charging system，CS)可以包括多个功率模块(即图1中的第一部分功率模块A(包括功率模块PM(power module)1、功率模块3、…、功率模块PM(N-1))和第二部分功率模块B(包括功率模块PM2、功率模块4、…、功率模块PMN)、分配开关模块(distributing switch module，DSM)和多个充电端口C(如图1中的充电端口(charging port，CP)1和充电端口CP2)。分配开关模块DSM可以包括分配单元(distributing unit，DU)1(即第一分配单元)和分配单元DU2(即第二分配单元)。
进一步地，参考图1，第一部分功率模块A中的每个功率模块和第二部分功率模块B中的每个功率模块(即图1中的功率模块PM1至功率模块PMT)各自的输入端与外部电源(power supply，PS)连接，第一部分功率模块A中功率模块的输出端通过分配单元DU1与充电端口CP1连接，充电端口CP1与电动汽车EV1连接，进而为电动汽车EV1充电。类似，第二部分功率模块B中功率模块的输出端通过分配单元DU2与充电端口CP2连接，充电端口CP2与电动汽车EV2连接，进而为电动汽车EV2充电。
从上述连接关系可以看出，分配单元DU1与第一部分功率模块A和充电端口CP1对应，分配单元DU2与第二部分功率模块B和充电端口CP2对应。
在图1所示结构的基础上，上述第一部分功率模块A和第二部分功率模块B中的每个功率模块(即功率模块PM1至功率模块PMN)可以用于：将来自外部电源PS的第一功率(可以用P 1表示)进行转换并输出第二功率(可以用P 2表示)。
进一步地，上述的分配单元DU1可以用于：将第一部分功率模块A中每个功率模块输出的第二功率P 2分配给充电端口CP1。与分配单元DU1类似，上述的分配单元DU2可以用于：将第二部分功率模块B中每个功率模块输出的第二功率P 2分配给充电端口CP2。
更进一步地，充电端口CP1可以用于：根据分配单元DU1分配的功率为电动汽车EV1充电。与充电端口CP1类似，充电端口CP2可以用于：根据分配单元DU2分配的功率为电动汽车EV2充电。
本申请实施例提供的充电系统通过分配开关模块DSM中的中的分配单元DU1和分配单元DU2将来自第一部分功率模块A和第二部分功率模块B中每个功率模块输出的功率(即第二功率P 2)分配给不同的充电端口(即充电端口CP1和充电端口CP2)，不仅能够通过不同的充电端口同时为不同的电动汽车(即电动汽车EV1和第二电动汽车EV2)充电，而且充电系统的输出功率能够满足不同电动汽车的充电需求，提高了电动汽车的充电速度和充电系统中功率模块的利用率。
需要说明的是，本申请实施例以同一个外部电源PS为多个功率模块提供第一功率P 1(即通过同一个外部电源PS为多个功率模块供电)为例，当然，还可以通过不同的外部电源为多个功率模块提供第一功率P 1。
进一步地，上述的第一功率P 1可以由外部电源PS的输出电压和输出电流共同确定，上述的第二功率P 2由功率模块的输出电压和输出电流共同确定。
更进一步地，外部电源PS的输出电压可以为直流电压，也可以为交流电压。
于是，在一示例中，当外部电源PS的输出电压为直流电压时，上述的功率模块可以为DC/DC转换模块。也就是说，功率模块可以将来自外部电源PS的一种电压等级直流电压进行转换，输出另一种电压等级的直流电压(即功率模块的输出电压可以为直流电压)。
例如，功率模块可以将来自外部电源PS的高电压等级的直流电压进行转换(如降压)，输出低电压等级的直流电压。
在另一示例中，当外部电源PS的输出电压为交流电压时，上述的功率模块可以为AC/DC转换模块。也就是说，功率模块可以将来自外部电源PS的交流电压进行转换(也可以叫做整流)，输出直流电压(即功率模块的输出电压可以为直流电压)。
需要说明的是，功率模块的输出电压的性质(即交流电压或者直流电压)是电动汽车所需的电压性质决定的。由于电动汽车通常所需的电压为直流电压，所以本申请上述实施例中功率模块的输出电压是以直流电压为例进行说明的。
可以理解的，如果电动汽车所需的电压为交流电压，存在以下两种情况：
情况一：当外部电源PS的输出电压为直流电压时，上述的功率模块可以为DC/AC转换模块。也就是说，功率模块可以将来自外部电源PS的直流电压进行转换(可以叫做逆变)，输出交流电压(即功率模块的输出电压可以为交流电压)。
情况二：当外部电源PS的输出电压为交流电压时，上述的功率模块可以为AC/AC转换模块。也就是说，功率模块可以将来自外部电源PS的一种电压等级交流电压进行转换，输出另一种电压等级的交流电压(即功率模块的输出电压可以为交流电压)。
例如，功率模块可以将来自外部电源PS的高电压等级的交流电压进行转换(如降压)，输出低电压等级的交流电压。

还例如，通过第二切换开关S2(N/2)可以实现功率模块PMN与功率模块PM(N-1)的互连。于是，可以第二切换开关S2(N/2)和第一切换开关S1(N-1)将功率模块PMN输出的第二功率P 2分配给充电端口CP1，还可以通过第二切换开关S2(N/2)和第一切换开关S1N将功率模块PM(N-1)输出的第二功率P 2分配给充电端口CP2。
需要说明的是，功率模块PM(N+1)无需与第二切换开关连接。
在一种可能的实现方式中，在图14的基础上，本申请实施例提供的充电系统CS还可以包括共享开关模块SSM和多个共享端口(本申请实施例以2个共享端口(即图15和图17中的共享端口SP1和共享端口SP2)为例)，如图15和图17所示。
进一步地，共享开关模块SSM可以包括共享单元SU1(即第一共享单元)和共享单元SU2(即第二共享单元)，如图15至图18所示。共享单元SU1可以包括第三切换开关S31、第三切换开关S33(即与功率模块PM3(图15和图17中未示出)连接的第三切换开关，图15至图18未示出)、…、第三切换开关S3(N-1)和第三切换开关S3(N+1)。共享单元SU2可以包括第三切换开关S32、第三切换开关S34(即与功率模块PM4(图15和图17中未示出)连接的第三切换开关，图15至图18未示出)、…、第三切换开关S3N和第三切换开关S3(N+2)。
于是，共享单元SU1中的第三切换开关可以将功率模块PM1、功率模块PM3、…、功率模块PM(N-1)和功率模块PM(N+1)与共享端口SP1连接，共享单元SU2中的第三切换开关可将功率模块PM2、功率模块PM4、…、功率模块PMN和功率模块PM(N+1)与共享端口SP2连接。也就是说，本申请实施例可以通过共享开关模块SSM中的共享单元SU1和共享单元SU2实现N+1个功率模块与共享端口SP1和共享端口SP2的连接。
可以理解的，共享开关模块SSM可以将N+1个功率模块与共享端口SP1和共享端口SP2连接。也就是说，本申请实施例可以通过共享开关模块SSM实现N+1个功率模块与共享端口SP1和共享端口SP2的连接。
参考图15和图16，共享开关模块SSM可以包括共享单元SU1和共享单元SU2中的N+2个第三切换开关(即图15和图16中的第三切换开关S31、第三切换开关S32、…、第三切换开关S3(N-1)、第三切换开关S3N、第三切换开关S3(N+1)、第三切换开关S3(N+2))。
从图15可以看出，N+2个第三切换开关可以将N+1个功率模块与共享端口SP1和共享端口SP2连接，也就是说，本申请实施例可以通过N个第三切换开关实现N个功率模块与共享端口SP1和共享端口SP2的连接。
例如，第三切换开关S3(N+1)可以将功率模块PM(N+1)与共享端口SP1连接，于是，第三切换开关S3(N+1)可以将功率模块PM(N+1)输出的第二功率P 2分配给共享端口SP1。
又例如，第三切换开关S3(N+2)可以将功率模块PM(N+1)与共享端口SP2连接，于是第三切换开关S3(N+2)可以将功率模块PM(N+1)输出的第二功率P 2分配给共享端口SP2。
结合图15和上述的连接关系可以看出，N+1个功率模块各自输出的第二功率P 2可以通过相应的第三切换开关共享给相应的共享端口，同时，通过控制第三切换开关动作可以控制共享端口传输的功率(即通过共享端口传输给下一充电系统的功率)。
需要说明的是，N个第一切换开关(即第一切换开关S11、第一切换开关S12、…、第一切换开关S1(N-1)、第一切换开关S1N)、N/2个第二切换开关(即第二切换开关S21、…、第二切换开关S2(N/2))以及N个第三切换开关(即第三切换开关S31、第三切换开关S32、…、第三切换开关S3N)各自与相应功率模块PM的连接关系和功率分配过程可以参考上文，本申请实施例在此不做赘述。
在图15和图16的基础上，上述的共享开关模块SSM除了包括N+2个第三切换开关(即图17和图18中的第三切换开关S31、第三切换开关S32、…、第三切换开关S3(N-1)、第三切换开关S3N、第三切换开关S3(N+1)、第三切换开关S3(N+2))，共享开关模块SSM还可以包括多个第四切换开关(即图5和图6中的第四切换开关S41、第四切换开关S42和第四切换开关S43)，如图17和图18所示。
从图17可以看出，共享单元SU1中的第三切换开关可以将功率模块PM1、功率模块PM3、…、功率模块PM(N-1)和功率模块PM(N+1)与共享端口SP1连接，共享单元SU2中的第三切换开关可以将功率模块PM2、功率模块PM4、…、功率模块PMN和功率模块PM(N+1)与共享端口SP2连接，第四切换开关S41、第四切换开关S42、第四切换开关S43可以将充电端口CP1、充电端口CP2、共享端口SP1和共享端口SP2连接。也就是说，本申请实施例可以通过N+2个第三切换开关实现N+1个功率模块与共享端口SP1 和共享端口SP2的连接，同时，本申请实施例还可以通过第四切换开关S41、第四切换开关S42、第四切换开关S43实现充电端口CP1、充电端口CP2、共享端口SP1和共享端口SP2之间的互连。
从图17和上述的连接关系可以看出，通过多个第三切换开关和多个第四切换开关可以将N+1个功率模块各自输出的第二功率P 2在充电端口CP1、充电端口CP2、共享端口SP1和共享端口SP2之间实现共享，同时可以控制共享端口传输的功率。
本申请实施例通过分配开关模块DSM和共享开关模块SSM可以将任一功率模块的输出功率分配至任一充电端口和任一共享端口，不仅提高了单个充电端口的充电功率以及单个功率模块的利用率，还通过共享开关模块SSM使充电系统具备对外共享功率的能力，大幅度提升充电系统的灵活性。
需要说明的是，图7至图10仅仅示出了本申请实施例提供的部分充电系统的结构图，当然，本申请实施例的技术方案还可以用于其他结构的充电系统，所有类似结构都属于本申请实施例的保护范围之内。
在一种可能的实现方式中，上述的第一切换开关、第二切换开关、第三切换开关和第四切换开关分别可以采用接触器、半导体开关(也可以叫做固态开关)或半导体混合开关(可以简称为混合开关)等。
进一步地，上述的接触器可以为单触点接触器(也可以叫做单极接触器)，还可以为双触点接触器(也可以叫做双极接触器)。当然，接触器还可以为其他类型的接触器，本申请实施例对此不作限定。
在一种可能的实现方式中，本申请实施例提供了一种共享系统(sharing system，SS)，如图19所示。共享系统SS可以包括M(M大于等于2，即至少2个)个并联的上述的充电系统(即图19中的充电系统CS1、充电系统CS2、…、充电系统CSM)。
本申请实施例提供的共享系统不仅能够通过不同充电系统的充电端口为不同电动汽车同时充电，且能够实现不同充电系统之间的功率共享，通过功率共享，大幅度提高了充电系统的输出功率(即充电系统通过充电端口为电动汽车提供的充电功率)。也就是说，功率共享不会影响共享系统为不同电动汽车的同时充电，提高了电动汽车充电的速度和充电系统中功率模块的利用率。
同时，本申请实施例提供的共享系统中的充电系统都是独立的模组，可以发现共享系统的模组化程度高，可以按照电动汽车的实际充电需求选择充电系统的数量，灵活性高。
在一种可能的实现方式中，如图20所示，相邻充电系统之间可以通过功率共享母线(也可以叫做连接导体)连接。
例如，充电系统CS1(可以为充电系统CS1的共享端口SP1)与充电系统CS2(可以 为充电系统CS1的共享端口SP1)之间通过功率共享母线(power sharing bus，PSB)1连接。
能够理解的，充电系统CS1的共享端口SP1可以认为是充电系统CS1的共享输出端口，由于充电系统CS1为共享系统SS的第一个充电系统，所以充电系统CS1可以只设置一个共享端口(作为充电系统CS1的共享输出端口)。
还能够理解的，由于中间的充电系统(即共享系统SS中除充电系统CS1和充电系统CSM以外的其他充电系统，如充电系统CS2等)需要和与相邻的充电系统连接，所以充电系统CS2等中间的充电系统可以设置共享端口SP1和共享端口SP2共两个共享端口。此处，如果功率是从充电系统CS1向充电系统CS2等中间的充电系统传输的，那么，充电系统CS2等中间的充电系统的共享端口SP1可以认为是共享输入端口，充电系统CS2等中间的充电系统的共享端口SP2可以认为是共享输出端口。
当然，由于功率的传输是双向的，因此，如果功率是从充电系统CS2等中间的充电系统向充电系统CS1传输的，那么，充电系统CS2等中间的充电系统的共享端口SP1则可以认为是共享输出端口，充电系统CS2等中间的充电系统的共享端口SP2可以认为是充电系统CS2等中间的充电系统的共享输入端口(此处可以是充电系统CS3等中间的充电系统向充电系统CS2传输功率)。
与充电系统CS1类似，充电系统CSM为共享系统SS的最后一个充电系统，所以充电系统CSM也可以只设置一个共享端口(作为充电系统CSM的共享输入端口)。
当然，如果需要在共享系统中M个充电系统的基础上进一步实现功率共享，或者为了实现充电系统的批量生产，可以给充电系统CS1设置共享端口SP2(图20中未示出，即充电系统CS1的共享输入端口)，还可以给充电系统CSM设置共享端口SP2(图20中未示出，即充电系统CSM的共享输出端)。也就是说，本申请实施例对充电系统设置的共享端口的数量不做限定。
从图20可以看出，本申请实施例可以通过不同的充电系统同时为不同的电动汽车充电。
例如，可以通过充电系统CS1的不同充电端口(如充电系统CS1的充电端口CP1和充电端口CP2)为不同电动汽车(如电动汽车EV1和电动汽车EV2)充电。
又例如，通过充电系统CS2的不同充电端口(如充电系统CS2的充电端口CP1和充电端口CP2)为不同电动汽车(如电动汽车EV3和电动汽车EV4)充电。
再例如，通过充电系统CSM的不同充电端口(如充电系统CSM的充电端口CP1和充电端口CP2)为不同电动汽车(如电动汽车EV5和电动汽车EV6)充电。
结合图7可以理解，图20示出的共享系统中的每个充电系统可以设置更多数量的充 电端口(即不止充电端口CP1和充电端口CP2这2个充电端口)。
例如，充电系统CS1还可以设置充电端口CP3(图20中未示出)和充电端口CP4(图20中未示出)，在不同充电系统之间共享分享的同时，通过多个充电端口实现多个电动汽车的充电。
从图20还可以看出，为了提高共享系统的可靠性，本申请实施例提供的共享系统中的每个充电系统(可以认为是充电系统的功率模块)可以通过不同的外部电源供电。
例如，充电系统CS1通过外部电源SP1供电。
又例如，充电系统CS2通过外部电源SP2供电。
再例如，充电系统CSM通过外部电源SPM供电。
当然，本申请实施例还可以通过同一外部电源为共享系统中的所有充电系统供电，或者可以多个(如2个或3个等)充电系统通过一个外部电源供电(即一个外部电源为部分充电系统供电)。本申请实施例对共享系统中的充电系统的供电方式不做限定。
在一种示例中，如图21所示，共享系统可以包括K个并联的充电系统(即图21中的充电系统CS1、充电系统CS2、…、充电系统CSK，每个充电系统均包括N个(即偶数个)功率模块)。相邻两个充电系统之间通过功率共享母线连接。例如，充电系统CS1与充电系统CS2之间通过功率共享母线PSB1连接。
从图21可以看出，充电系统CS1可以通过充电系统CS1的充电端口CP1和充电端口CP2为不同的电动汽车充电，同时可以通过充电系统CS1的共享端口SP2将功率共享传输给充电系统CS2。
与充电系统CS1类似，充电系统CS2可以通过自身的共享端口SP1接收充电系统CS1共享的充电系统CS1的功率，并通过充电系统CS2的充电端口CP1和充电端口CP2为不同的电动汽车充电。同时，通过充电系统CS2的三个第四切换开关可以将充电系统CS1的功率共享至充电系统CS2，或可以通过充电系统CS2的共享端口SP1、共享端口SP2以及其中一个第四切换开关将充电系统CS1的功率共享给充电系统CS2之后的充电系统CS(如充电系统CS3，充电系统CS3在图21中未示出)。
需要说明的是，上述通过充电系统CS2的三个第四切换开关可以将充电系统CS1的功率共享至充电系统CS2的过程不会影响充电系统CS2内部的充电端口的使用，也就是说，不会影响充电系统CS2通过自身的充电端口CP1和充电端口CP2给电动汽车充电。
还需要说明的是，上述的通过充电系统CS2的共享端口SP2将充电系统CS1的功率共享给充电系统CS2的之后充电系统CS的过程中，充电系统CS2的三个第四切换开关为充电系统CS1的功率共享至充电系统CS2的之后充电系统CS提供了一个功率的传输通道，该过程也不会影响充电系统CS2内部的充电端口的使用。
需要说明的是，由于功率具有双向传输特性，所以如上所述，充电系统CS1可以将自身的功率共享给充电系统CS2，充电系统CS2还可以将自身的功率共享给下一充电系统CS。当然，充电系统CS2还可以将自身的功率共享给充电系统CS1。
还需要说明的是，图21提供的共享系统中其余充电系统CS(如充电系统CSK与充电系统CS(K-1)(充电系统CS(K-1)在图21中未示出)等)之间的功率共享原理同上，本申请实施例在此不做赘述。
在另一示例中，结合上文的图12示出的包括4个充电系统CS(每个充电系统CS均包括4个功率模块PM)对本申请实施例提供的共享系统进行详细介绍。
如图22所示，共享系统可以包括K个并联的充电系统(即图21中的充电系统CS1、充电系统CS2、…、充电系统CSK)。相邻两个充电系统之间通过功率共享母线连接。例如，充电系统CS1与充电系统CS2之间通过功率共享母线PSB1连接。
从图22可以看出，充电系统CS1可以通过充电系统CS1的充电端口CP1和充电端口CP2为不同的电动汽车充电，同时可以通过充电系统CS1的共享端口SP2将功率共享传输给充电系统CS2。
同样，充电系统CS2可以通过自身的共享端口CP1接收充电系统CS1共享的功率，并通过充电系统CS2的充电端口CP1和充电端口CP2为不同的电动汽车充电，同时，充电系统CS2还可以通过充电系统CS2的共享端口SP2将功率共享传输给下一个充电系统CS(如充电系统CS3，充电系统CS3在图22中未示出)。
需要说明的是，由于功率具有双向传输特性，所以如上所述，充电系统CS1可以将自身的功率共享给充电系统CS2，充电系统CS2还可以将自身的功率共享给下一充电系统CS。当然，充电系统CS2还可以将自身的功率共享给充电系统CS1。
还需要说明的是，图22提供的共享系统中其余充电系统(如充电系统CSK与充电系统CS(K-1)(充电系统CS(K-1)在图22中未示出)等)之间的功率共享原理同上，本申请实施例在此不做赘述。
在再一示例中，结合上文的图17示出的包括K个充电系统(每个充电系统CS均包括N+1个(即奇数个)功率模块)对本申请实施例提供的共享系统进行详细介绍。
如图23所示，共享系统可以包括K个并联的充电系统(即图21中的充电系统CS1、充电系统CS2、…、充电系统CSK)。相邻两个充电系统之间通过功率共享母线连接。例如，充电系统CS1与充电系统CS2之间通过功率共享母线PSB1连接。
从图23可以看出，充电系统CS1可以通过充电系统CS1的充电端口CP1和充电端口CP2为不同的电动汽车充电，同时可以通过充电系统CS1的共享端口SP2将功率共享传输给充电系统CS2。
同样，充电系统CS2可以通过自身的共享端口SP1接收充电系统CS1共享的功率，并通过充电系统CS2的充电端口CP1和充电端口CP2为不同的电动汽车充电，同时，充电系统CS2还可以通过充电系统CS2的共享端口SP2将功率共享传输给下一个充电系统CS(如充电系统CS3，充电系统CS3在图23中未示出)。
需要说明的是，由于功率具有双向传输特性，所以如上所述，充电系统CS1可以将自身的功率共享给充电系统CS2，充电系统CS2还可以将自身的功率共享给下一充电系统CS。当然，充电系统CS2还可以将自身的功率共享给充电系统CS1。
还需要说明的是，图23提供的共享系统中其余充电系统(如充电系统CSK与充电系统CS(K-1)(充电系统CS(K-1)在图23中未示出)等)之间的功率共享原理同上，本申请实施例在此不做赘述。
结合图21、图22和图23可以看出，共享系统中不同充电系统之间可以实现功率共享，且不受每个充电系统中功率模块PM数量的限制。也就是说，不管充电系统中功率模块有多少个，共享系统中不同充电系统之间均可以实现功率共享，而且，每个充电系统还可以在共享功率的同时为不同电动汽车进行充电。
综上所述，本申请实施例提供的上述如图21、图22和图23所示的包括K个充电系统的共享系统不仅可以实现每个充电系统为不同的电动汽车充电，同时还可以实现所有充电系统之间的功率共享。
需要说明的是，充电系统的详细介绍可以参考上文，本申请实施例在此不做赘述。
在一种可能的实现方式中，相邻充电系统之间连接的功率共享母线可以为铜排、铝排或者线缆等，本申请实施例对功率共享母线的类型不做限定。
在另一种可能的实现方式中，上述的功率共享母线上可以设置控制开关或者连接件。
可选地，上述的控制开关可以为接触器、断路器或者隔离开关等。同样，此处的接触器也可以为单触点接触器(也可以叫做单极接触器)，或者可以为双触点接触器(也可以叫做双极接触器)。当然，接触器还可以为其他类型的接触器，本申请实施例对此不作限定。
可选地，上述的连接件可以采用连接器或者可拆卸铜排等，本申请对此不作限定。
当然，本申请还可以在功率共享母线上设置其他具有能够实现通断功能的设备，本申请实施例对此不作限定。
