本发明实施例一提供了一种储能系统，如图1所示，包括：
M个储能电池1和通讯链路3，每个储能电池1均对应设置有一个控制器2，所述控制器2通过执行控制软件从而对对应的储能电池1进行控制；M个控制器2均能够通过所述通讯链路3进行数据通信；所述控制软件对应有版本号，且控制软件越新，则版本号越高；M为自然数，M≥2；这里，该储能电池1中可以包含有多个电芯，这些电芯串联或并联从而构成了该储能电池1，该储能电池1可以为镍氢电池、镍镉电池和锂电池等，该控制器2可以为单片机等，该通信链路可以为以太网，光纤网络，CAN(Controller Area Network，控制器域网)等；所述控制器2通过执行控制软件从而对对应的储能电池1进行充电、放电、接入该储能系统中或从该储能系 统中旁路等控制。每个控制器2中通常会设置有一个存储装置，在该存储装置中存储有该控制软件。
这里，该控制软件可以包含有可执行软件部分，配置信息等。
每个控制器2均用于：获取本控制器对应的控制软件的第一版本号，并基于所述通信链路向其余M-1个控制器2都发送第一版本号，并接收其余M-1个控制器2所发送的第二版本号；从第一版本号和M-1个第二版本号中选择最高的目标版本号，并获取目标版本号对应的目标控制器；当本控制器对应的控制软件的第一版本号低于目标版本号时，本控制器为待升级控制器；在实际中，当某个控制器2在运行时，则该控制器2即为“本控制器”。
这里，由于每个控制器2均会向其余M-1个控制器2发送其版本号，因此，每个控制器2均能够接收到其余M-1个控制器2所发送的版本号，每个控制软件都对应有版本号，且控制软件越新，则版本号越高。此外，该版本号具有一个固定的格式，例如，V1.0，V1.1，V1.2，V1.21等，因此，基于预定的格式，就可以对版本号比较高低。例如，V1.0<V1.1<V1.2<V1.21。
M个控制器2都能够通过所述通讯链路3进行数据通信，则每个控制器2都具有唯一的通信地址，因此，当接收到某个控制器2所发送的版本号之后，还可以得到该控制器2的通信地址，于是，就可以在该版本号与通信地址之间建立对应关系，即使用通信地址来标记该控制器2。此外，还可以为每个控制器2都设置一个唯一的标识符，在本控制器向其余M-1个控制器2都发送版本号时，也会同时发送本控制器的标识符，于是，每个控制器2就可以在版本号与标识符之间建立对应关系，此外，只要获知某个控制器2的标识符，就可以基于该标识符向该控制器2发送数据。
这里，当多个控制器2对应的控制软件的版本号一样，且都是最高的，则目标版本号对应的控制器2的数量可能为多个，则可以从中选择出一个作为目标控制器。
所述待升级控制器用于：通过所述通讯链路3向所述目标控制器发送升级请求指令，且在接收到升级数据时，基于所述升级数据，将对应的控制软件进行升级；当第一版本号低于目标版本号时，则表明本控制器对应的控制软件相对于目标控制器的控制软件是比较旧的，因此，就可以进行升级了，即从目标控制器中下载最新的升级数据，来对本地的较旧的控制软件进行升级。
所述目标控制器用于：通过所述通讯链路3从待升级控制器接收到升级请求指令，并生成控制软件在待升级控制器对应的版本号和目标版本号之间的升级数据，并通过所述通讯链路3将升级数据发送给待升级控制器。
这里，在该储能系统中，该升级过程可以由目标控制器主动发起、还可以由待升级控制器主动发起，即：1、由目标控制器主动发起该升级过程，目标控制器可以根据该储能系统的状况来 决定是否发起该升级过程，比如：如果该储能系统时处于工作中，则不建议发起该升级过程，如果处于空闲中，则建议发起该升级过程；如果决定发起该升级过程，则该目标控制器可以向其余的M-个控制器2都发送升级指令，该升级指令至少包括目标版本号，于是，当某个控制器2确定其为待升级控制器时，开启该升级过程；2、当某个控制器2确定其为待升级控制器时，会自动与目标控制器建立起数据传输通道，并开启该升级过程。
综上所述，在储能系统中，只要一个储能电池1的控制软件升级了，其余的储能电池1会主动的进行升级，非常的简单方便。
这里，可以理解的是，在执行该升级操作时，不能百分之百的确保控制软件的升级一定成功，因此，在对控制软件进行升级之前，需要将该目标软件进行备份。例如：在存储装置中需要设置一个备份区，首先将该控制软件拷贝到备份区，然后，操作“基于所述升级数据，将对应的控制软件进行升级”具体包括：基于所述升级数据，将备份区中的控制软件升级为所述目标版本号对应的控制软件；然后本控制器重启，再重启之后，执行备份区中的控制软件，然后，使用备份区中的控制软件来覆盖原先的控制软件。
可选的，该待升级控制器还执行以下操作：在接收到目标控制器发送的重启指令之后，重启，然后执行升级后的控制软件。
这里，升级数据可以为：目标版本号所对应的完整软件数据，或者，该控制软件在第一版本号与目标版本号之间的差异数据。
这里，在每个控制器2进行升级的过程中，可以存储有升级前的控制软件和升级后的控制软件之间的差异，目标控制器在升级其控制软件的时候，也会存储升级前的控制软件和升级后的控制软件之间的差异，因此，如果目标控制器存在第一版本号和目标版本号之间的数据差异，可以直接发给本控制器。
本实施例中，所述“接收到升级数据”具体包括：接收到升级数据和校验数据；所述“基于所述升级数据，将对应的控制软件进行升级”具体包括：基于校验算法和校验数据，确定所述升级数据通过校验时，基于所述升级数据将对应的控制软件进行升级。这里，在该通讯链路3上传输升级数据的时候，有可能会发生数据错误，因此，需要设置有校验数据，从而确保升级数据的正确性和完整性。
本实施例中，所述校验数据为所述升级数据的CRC(Cyclic Redundancy Check，循环冗余校验)校验码，所述校验算法为CRC校验算法
本实施例中，所述“生成控制软件在待升级控制器对应的版本号和目标版本号之间的升级数据”具体包括：生成控制软件在待升级控制器对应的版本号和目标版本号之间的差异数据。
这里，当目标控制器接收到第一版本号对应的控制软件之后，就可以获知在第一版本号和目标版本号之间，该控制软件到底在哪些部分被修改了，从而就有可能先将目标版本号和第一版本号之间的差异数据给计算出来，然后再发送给本控制器。
本实施例中，所述“通过所述通讯链路3向所述目标控制器发送升级请求指令”具体包括：通过所述通讯链路3向所述目标控制器发送升级请求指令，所述升级请求指令包含有待升级控制器对应的第一控制软件；这里，第一控制软件可以为该控制软件的全部，也可以为该控制软件的部分。例如，可执行软件部分或配置信息等。
所述“通过所述通讯链路3从待升级控制器接收到升级请求指令，并生成控制软件在待升级控制器对应的版本号和目标版本号之间的差异数据”具体包括：从待升级控制器接收其对应的第一控制软件，获取目标版本号对应的第二控制软件，生成第二控制软件相对于第一控制软件的若干改进的数据块D，从而得到N个三元组C
i[数据块D
i的起始地址B
i，数据块D
i的结束地址E
i，数据块D
i]，其中，N和i均为自然数，i＝1,2,...,N，所述升级数据包含有N个三元组C
i；
这里，将第二控制软件和第一控制软件进行比较，从而就可以得到第二控制软件相对于第一控制软件之间的改进数据。可以使用以下比较方法：
方法一、可以将第二控制软件和第一控制软件进行逐位或逐比特的比较，从而就可以得到若干改进的数据块D；这里，当第二控制软件的长度<第一控制软件的长度，即第一控制软件的末尾，有部分需要被截掉，则需要包含有一个三元组C，在该三元组C中，数据块的内容为空或字符“NULL”等，即三元组C中的起始地址至结束地址的部分数据需要截掉；当第二控制软件的长度>第一控制软件的长度，即第一控制软件的末尾需要增加部分数据，则需要包含有一个三元组C，在该三元组C中，数据块的内容为需要增加的数据，即三元组C中的起始地址为第一控制软件的末尾的地址+1；
在实际中，控制软件通常都会包含有多个文件，有些文件是可执行的二进制文件，有些文件是字符文件，因此，第二控制软件和第一控制软件进行比较时，可以首先提取出这些文件，然后进行比较逐文件进行比较；可选的，如果是二进制文件，则当两个二进制文件存在差异时，可以将第二控制软件中的较新的二进制文件利用三元组发回；而如果是字符文件，可以将两个字符文件进行逐字符的比较，从而就可以得到若干改进的数据块D；这里，当新的字符文件的长度<旧的字符文件的长度，即旧的字符文件的末尾，有部分字符需要被截掉，则需要包含有一个三元组C，在该三元组C中，数据块的内容为空或字符“NULL”等，即三元组C中的起始地址至结束地址的部分数据需要截掉；当新的字符文件的长度>旧的字符文件的长度，即旧的字符文件的末尾需要增加部分字符，则需要包含有一个三元组C，在该三元组C中，数据块的内容为需要增加的 字符串，即三元组C中的起始地址为旧的字符文件的末尾的地址+1。
所述“基于所述升级数据，将对应的控制软件进行升级”具体包括：对每个三元组C
i[数据块D
i的起始地址B
i，数据块D
i的结束地址E
i，数据块D
i]均执行以下操作：当数据块D
i为空时，将本控制器对应的控制软件中的在地址B
i至E
i的数据清空；当数据块D
i不为空且“数据块D
i的长度＝E
i-B
i+1”时，将本控制器对应的控制软件中的在地址B
i至E
i的数据替换为据块D
i。
本实施例中，还包括以下步骤：当“数据块D
i的长度≠E
i-B
i+1”时，发出报警，停止升级。
本实施例中，所述“基于所述通信链路向其余M-1个控制器2都发送第一版本号，并接收其余M-1个控制器2所发送的第二版本号”具体包括：基于所述通信链路向其余M-1个控制器2都发送第一版本号和本控制器对应的储能电池1的序列号，并接收其余M-1个控制器2所发送的第二版本号和序列号；所述“获取目标版本号对应的目标控制器”具体包括：当目标版本号对应多个控制器2时，从所述多个控制器2中、选择序列号最高的作为目标控制器。
本实施例中，所述通讯链路3为CAN(Controller Area Network，控制器局域网络)通讯链路3。
本实施例中，所述“基于所述升级数据，将对应的控制软件进行升级”具体包括：将本控制器对应的待升级的第三控制软件拷贝至备份区，基于所述升级数据，将备份区中的控制软件升级为升级之后的第四控制软件；在重启时，将第四控制软件覆盖第三控制软件。
本实施例中，所述“通过所述通讯链路3向所述目标控制器发送升级请求指令”具体包括：在接收到目标控制器发送的升级指令之后，通过所述通讯链路3向所述目标控制器发送升级请求指令。
