户外运动已经成为人们在闲暇时段推崇的休闲娱乐方式，而高质量的户外运动需要多样化的装备以及设备的支持。与此同时，为了降低户外运动的成本，人们通常会将居家场景中使用的装备或设备、比如电饭煲以及电热水壶等小型家电，应用到户外运动的场景中来，这类设备需要借助于电能供给设备提供匹配且稳定的电能才能正常运行。
针对以上技术问题，在户外场景中户外便携式储能设备比如户外电源受到了广泛的欢迎。然而，单一的户外电源通常无法满足各种电能消耗设备的电能使用需求，同时，若设计单台能够满足大部分的家用电器电能消耗需求的户外电源，则需要将户外电源的输出功率设计在大于2KW的范围。然而，这样的输出功率范围势必导致户外电源体积以及重量的骤然增大，从而使得单台户外电源失去便携性这一优势。
为了降低对户外电源的便携性的消极影响，相关技术中还提出了对多台户外电源进行并机配置，以满足大部分家用电器的电能消耗需求。然而，相关技术中的并机配置方案，需要并机配置人员具备丰富的并机配置经验以及电路连接检查知识。因此，这样的并机配置方式灵活性不足。

在一种实施方式中，目标信息还可以包括第二设备下发的停止并机状态的指令。
在一种实施方式中，第四状态可以包括断开状态；示例性地，开关模块107中的第二开关单元(图中未示出)可以设置在检测模块106与AC电能输出模块105之间，因此，第一控制模块104通过控制第二开关单元切换至断开状态，从而断开第四连接；示例性地，第四连接可以为电性连接。
由以上可知，本申请实施例提供的储能设备中的第一控制模块，在获取到目标信息之后，能够控制开关模块的开关状态切换至第四状态，且目标信息至少包括储能设备处于异常状态的信息，如此，能够在储能设备切换至异常状态之后，实时的对第四连接进行控制，从而能够降低储能设备异常状态时依然输出电能产生的风险，进而实现了在并机过程中对储能设备的主动保护。
基于前述实施例，本申请实施例提供的储能设备1中，AC输出模块105，被配置为在第四连接断开、且储能设备处于并机状态时，输出第二AC电能。
示例性地，在第四连接断开、且储能设备处于并机状态时，若AC输入模块102仍然能够接收第一设备传输的第二AC电能，则第一控制模块104可以控制开关模块107保持第三状态，从而使得AC输出模块105可以将第二AC电能输出。
示例性地，在储能设备1处于异常状态时，第一通信模块103可以通过第一连接将异常状态发送至第二设备，以供第二设备生成电能均衡指令，并将电能均衡指令发送至参与并机的其它正常状态的储能设备，以供这些储能设备进行电能输出均衡，从而改善并机过程中电能输出的稳定性和持续性。
由以上可知，本申请实施例提供的储能设备中的AC输出模块，能够在第四连接断开、且储能设备处于并机状态时，输出第二AC电能，从而能够降低储能设备异常状态对并机电能输出的影响，进而提高并机的储能设备的电能输出的稳定性和持续性。
基于前述实施例，本申请实施例提供的储能设备1中的第一通信模块103，还被配置为通过第一连接接收第二设备下发的设备标识；第一控制模块104，被配置为在设备标识不为指定标识时，控制AC输入模块102接收第二AC电能。
示例性地，若设备标识为指定标识，则第一控制模块104可以控制AC输入模块102处于非工作状态，从而不接收第二AC电能。
在一种实施方式中，设备标识可以是用户输入至第二设备的；示例性地，设备标识可以是第二设备为与其建立有通信连接的各个储能设备自动设置的标识；示例性地，第二设备可以根据与其建立通信连接的时间顺序、通信连接的制式类型、通信连接的稳定性、各个储能设备中剩余DC的数量中的至少一种生成设备标识。
在一种实施方式中，设备标识可以通过字符和/或数字的形式体现，比如第一个储能设备的设备标识可以为1，第二个储能设备的设备标识可以为2；示例性地，设备标识中的最大值可以为与第二设备建立有第二连接的储能设备的数量，比如，若有n个储能设备与第二设备建立有通信连接，则设备标识的最大值可以为n，其中，n可以为大于或等于2的整数。
在一种实施方式中，指定标识可以为第二设备发送至储能设备1的；示例性地，指定标识可以是预先设定的、多个设备标识中的任一标识；示例性地，指定标识可以为设备标识的最小值，比如1；示例性地，设备标识的编号可以体现并机过程中各个储能设备的并机顺序，比如，设备标识为k的储能设备的AC输出模块输出的AC电能，可以输入至设备标识为k+1的储能设备的AC输入模块，其中，k为大于1的整数；示例性地，设备标识为指定标识时，比如设备标识为1，则第一个储能设备的AC输入模块无法接收其它储能设备输出的AC电能，而只能将其输出的AC电能输入至第二个储能设备。
在一种实施方式中，可以将参与并机设置的多个储能设备中的第一个至第n-1个储能设备称为从电能输出设备，而将第n个储能设备称为主电能输出设备；示例性地，主电能输出设备的AC输入模块能够接收第一个至第n-1个储能设备输出的AC电能，并将第一个至第n-1个储能设备输出的AC电能与其自身输出的AC电能进行合并输出；示例性地，主电能输出设备的AC输出模块可以连接至耗电设备。
由以上可知，本申请实施例提供的储能设备中，第一通信模块能够通过第一连接接收第二设备下发的设备标识；并且，第一控制模块能够在设备标识不为指定标识时，控制AC输入模块接收第二AC电能，如此，第二设备通过发送设备标识的形式，就能够简洁高效的控制储能设备的AC输入模块的工作状态；并且，储能设备通过判断其所收到的设备标识与指定标识之间的关系，就能够灵活的控制AC输入模块的工作状态，并能够确定储能设备在并机设备群中的角色信息，从而为并机过程AC电能的稳定安全传输奠定基础。
基于前述实施例，本申请实施例提供的储能设备1中，AC输入模块102包括第一接头，第一接头与AC电源线的母接头匹配；AC输出模块105包括第二接头；第二接头与AC电源线的公接头匹配。
在一种实施方式中，第一接头与第二接头的数量可以为多个，且各个第一接头可以分别与AC电源线的母接头匹配，各个第二接头可以分别与AC电源线的公接头匹配。
在实际应用中，具备并机功能的储能设备之间需要特定的并机线才能实现电能的传输。
而本申请实施例提供的储能设备的AC输入模块包括的第一接头与AC电源线的母接头匹配，且AC输出模块包括的第二接头与AC电源线的公接头匹配，从而使得储能设备能够通过AC电源线接收第一设备发送的第二AC电能，也能通过AC电源线输出第一AC电能、或第一AC电能与第二AC电能的合并电能、或第二AC电能，从而能够降低对特定的并机线的依赖，进一步提高了并机操作的灵活性，而且还能降低并机的设备成本。

如图4所示，双向逆变模块101可以为由四个金属-氧化物半导体场效应晶体管(Metal-Oxide-Semiconductor Field-Effect Transistor，MOSFET)Q1、Q2、Q3以及Q4组成的全桥逆变电路，其通过Vbus端口可以接收储能模块中的DC电能，并通过上述全桥逆变电路将DC电能转换为第一AC电能。
在图4中，AC输入模块102可以通过火线和零线接收第一设备发送的第二AC电能；在图4中，检测模块106可以包括第一检测单元H1以及第二检测单元H2，其中，第一检测单元H1以及第二检测单元H2可以分别实现对第一AC电能以及第二AC电能的电流检测；示例性地，第一检测单元H1以及第二检测单元H2可以分别为霍尔器件，其中，第一检测单元H1以及第二检测单元H2的端口5至8分别被配置为接地、接入参考电压、向第一控制模块输出检测结果以及接入3.3V的偏置电压；第一检测单元H1的端口3和4分别被配置为接入第一AC电能，端口1和2分别被配置为输出第一AC电能至第二检测单元的4端口；第二检测单元H2的端口1和2分别被配置为接入第二AC电能，端口3可以悬空设置，端口4可以输出第二AC电能，同时与第一AC电能进行合并，然后将合并后的第一AC电能以及第二AC电能传输至AC输出模块105，并通过AC输出模块105的火线和零线输出。
示例性地，在第一通信模块未接收到并机指令时，第一控制模块能够控制开关模块107中的开关K1以及开关K2处于断开状态，此时AC输入模块102无法接收第一设备传输的第二AC电能。
示例性地，在第一通信模块接收到并机指令后，第一控制模块可以控制储能设备切换至并机状态，并控制开关K1至开关K3均切换至闭合状态，此时AC输入模块102可以接收第一设备传输的第二AC电能，并将第二AC电能传输至第二检测单元H2，同时，双向逆变模块101输出的第一AC电能传输至第一检测单元H1，并通过第一检测单元H1的端口1和2将第一AC电能传输至第二检测单元H2的端口4，并在此处完成第一AC电能以及第二AC电能的合并，合并后的第一AC电能以及第二AC电能可以通过AC输出模块105输出至AC耗电设备、或下一 个储能设备的AC输入模块。

示例性地，当第一储能设备2以及第二储能设备3接收到第二设备发送的并机指令之后，它们能够分别在第一MCU 209以及第二MCU 309的控制下切换至并机状态；示例性地，第一储能设备2以及第二储能设备3还可以根据第二设备发送的设备标识，确定第一储能设备2为从电能输出设备，第二储能设备3为主电能输出设备，从而使得第一储能设备2的第一输入模块201处于非工作状态、且第二开关208处于断开状态，而第二储能设备3的第二输入模块301处于工作状态，从而能够接收第一储能设备2的第一输出模块210输出的AC电能。
示例性地，第一MCU 209可以控制第一开关207切换至闭合状态，从而使得第一逆变处理模块202输出的AC电能即前述实施例中的第二AC电能、经过第一频率检测单元203以及第一电流检测单元205、第一开关207与第一输出模块210之间的通路，传输至第二储能设备3的第二输入模块301。
示例性地，第二输入模块301可以将第一AC电能传输至第三频率检测单元303，以供其对第一AC电能进行频率检测得到第一参数，同时，第四频率检测单元304可以对第二AC电能进行频率检测，得到第二参数；示例性地，第三频率检测单元303以及第四频率检测单元304可以分别将第一参数以及第二参数，发送至第二MCU 309，以供第二MCU 309确定是否执行并机操作；示例性地，若第二MCU 309确定能够执行并机操作，则可以将能够执行并机操作的结果发送至第二设备，同时还可以控制第三开关307以及第四开关308分别切换至闭合状态，如此，第一AC电能经过第三电流电测单元305的电流检测之后、第二AC电能经过第四电流检测单元306的电流检测之后，可以在第三开关307处进行合并，并将合并结果传输至第二输出模块301以供其输出至下一个储能设备，或输出至AC耗电设备。
示例性地，在并机输出电能的过程中，任一储能设备可以发送DC剩余电量至第二设备，以供第二设备确定是否发送电能均衡指令至各个储能设备，从而供各个储能设备之间执行电能均衡操作，从而改善电能输出的稳定性。
示例性地，若第二储能设备3检测到其中的至少一个模块状态异常，则可以自动的、或基于第二设备的控制而控制第二逆变处理模块302停止工作，或断开第一AC电能的传输通路，但仍然保持第四开关308的闭合状态，从而能够将第二AC电能稳定输出。
示例性地，第一储能设备2与第二储能设备3之间可以通过AC电源线连接，从而实现第二AC电能的传输。
由以上可知，本申请实施例提供的储能设备，能够自动的执行并机操作，且能够在并机 传输电能的过程中实时的处理异常状态，保障并机状态下电能的稳定输出，并且，通过AC电源线连接各个储能设备，还能降低并机电能传输的硬件成本；与此同时，基于第二设备的无线控制实现并机连接，也大大提高了并机操作的灵活性。
