具体实施方式
下面将结合本申请实施例中附图，对本申请实施例中的技术方案进行描述。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步定义和解释。同时，在本申请的描述中，术语“第一”、“第二”等仅用于区分描述，而不能理解为指示或暗示相对重要性。
为了更好地管理电池，通常需要不定时的获取电池中各电池单体的工作参数，例如，电池单体的温度、电流、电压等参数，从而可以更好地实现电池的管理以及电池的安全情况的监控。
发明人研究了解到目前对电池中的各电池单体的管理是通过提前在电池中的各个位置设置传感器，通过该传感器采集周边数个电池单体的工作参数。然后各个传感器可以与电池的电池管理单元连接，从而可以使电池管理单元可以获得传感器采集的数据。通常情况下，如果电池中布置的传感器较少的话，所需连接在传感器与电池管理单元的线也就相对简单，操作起来也较为容易，但是这就不可避免的不能很好地对各个电池单体的情况进行准确定位；如果在电池中布置较多的传感器，例如，每个电池单体都布置有一个或多个传感器，可以使传感器采集到的数据更好地与电池单体对应上，也能够很好地对各电池单体的情况进行准确定位，但是这不可避免的是连接在传感器与电池管理单元的线也相对复杂，厂线操作复杂，布线的效率低。

步骤410，获取电池中的电池单体的位置信息。
可选地，可以先确定出电池的起始位置，该起始位置可以是电池中最边缘的电池单体。例如，该电池中包括M行N列电池单体为例，该起始位置可以是第一行第一列的电池单体所在位置。然后，从该起始位置，按照电池单体在电池中的排列方式依次确定电池中的各单体电池的位置信息。
示例性地，可以通过图像识别的方式对电池进行识别，以确定电池的起始位置。
示例性地，电池单体的位置信息可以通过坐标表示，例如，其中该坐标分别表示电池单体在电池中的行数以及列数。例如，一个电池单体位于电池中的第m1行，第n1列，则该电池单体的位置信息可以表示为(m1，n1)。
示例性地，电池单体的位置信息也可以是一个数值、或关键字符加数值，以电池中包括多个电池单体为例，可以通过一个数值表示电池单体在电池中的位置的位置信息。例如，一个电池中的电池单体按照图1所示的实例中进行排序的位序为10，则该电池单体的位置信息可以为10。该位置信息可以通过一个或多个数值以及关键字符表示各电池单体在电池中的位置。例如，一个电池中的电池单体按照图1所示的实例中进行排序的位序为10，则该电池单体的位置信息可以为P10，其中，P表示位置标记，10表示电池单体的位序。
示例性地，电池单体的位置信息也可以是多个数值、或关键字符加数值，以电池中包括多个电池模组，每个电池模组包括多个电池单体为例，该位置信息可以包括通过多个数值表示各电池单体在电池中的位置的位置信息。例如，一个电池单体位于第3个电池模组中，且该电池单体在第3个电池模组中的位序为7，则该电池单体的位置信息可以表示为3-7。该位置信息可以通过多个数 值以及关键字符表示各电池单体在电池中的位置。例如，一个电池单体位于第3个电池模组中，且该电池单体在第3个电池模组中的位序为7，则该电池单体的对应关系信息可以为M3-7，其中，M表示电池模组标记，3表示电池模组在电池中的位序，7表示电池单体在电池模组中的位序。
步骤420，获取该电池单体的功能芯片的芯片标识信息。
其中，功能芯片为安装在电池单体上的，用于对单体电池进行监控、采集电池单体的工作参数的芯片。例如，该功能芯片可以为电芯监控单元。该芯片标识信息可以是每个电池单体的电芯监控单元的唯一标识。该芯片标识信息可以是二维码、条形码、字符串等能够唯一表示该电芯监控单元的标识。该芯片标识信息可以跟随其数据发送，也就是电芯监控单元发送的每一帧数据都可以携带有其芯片标识信息。
示例性地，若电池中包括多行多列电池单体，可以从第一行第一列开始依次获取电池中每个电池单体的芯片标识信息。以一块电池中包括M行N列电池单体为例，可以从第一行第一列开始依次获取第一行的电池单体的芯片标识信息，直到获取第一行第N列的电池单体的芯片标识信息后，第二行从第二行第N列开始依次获取第二行的电池单体的芯片标识信息，直到获取第二行第一列的电池单体的芯片标识信息后，从第三行第一列开始获取依次获取第三行的电池单体的芯片标识信息，以此类推，获取整个电池中各个电池单体的芯片标识信息。
当然，在获取每一行的电池单体的芯片标识信息也可以均从第一列开始获取。
示例性地，若电池中包括多个电池模组，每个电池模组包括多行多列电池单体。可以按照电池模组的排序依次获取每个电池模组中的所有电池单体的芯片标识信息，针对每一个电池模组，可以依次获取各个电池模组中各个电池单体的芯片标识信息，例如，可以从第一行第一列开始依次获取电池中每个电池单体的芯片标识信息。以第一个电池模组中包括M1行N1列电池单体为例，可以从第一行第一列开始获取依次获取第一行的电池单体的芯片标识信息，直到获取第一行第N1列的电池单体的芯片标识信息后，第二行从第二行第N1列开始依次获取第二行的电池单体的芯片标识信息，直到获取第二行第一列的电池单体的芯片标识信息后，从第三行第一列开始获取依次获取第三行的电池单体的芯片标识信息，以此类推，获取整个电池中各个电池单体的芯片标识信息。
可选地，上述的步骤410和步骤420可以交替进行，例如，在每获取一个电池单体的位置信息后，即可获取该电池单体的功能芯片的芯片标识信息。因此，在每次获得该电池单体的位置信息和芯片标识信息后，即可将两项信息进行关联。
可选地，也可以在通过步骤410获得电池中所有电池单体的位置信息后，再获得各个电池单体的功能芯片的芯片标识信息。再基于各位置信息与芯片标识信息的关系，构建位置信息和芯片标识信息的对应关系信息。
可选地，在步骤410与步骤420的先后顺序也可以不以图4所示的示例为限，例如，可以在获取各个电池单体的芯片标识信息时，可以按照获取顺序依次存放各芯片标识信息，然后按照各个芯片标识信息的存放顺序，确定出各电池单体的位置信息。例如，若该电池中包括96个电池单体，则可以将96项芯片标识信息依次存放呈一个有序的数组。例如，一芯片标识信息被存放在37的位置处，则可以表示该芯片标识信息对应的电池单体在电池中的位置位于第37位，则该电池单体的位置信息可以表示为37或者P37等。
步骤430，将该电池单体的该位置信息和该芯片标识信息的对应关系信息存入该电池的电池管理单元中。
其中，芯片标识信息可以用于在电池管理单元与电池单体的功能芯片之间实现通信功能。例如，电池管理单元需要与各功能芯片进行通信时，可以通过该标识信息实现与该功能芯片通信。
其中，该对应关系信息用于表示电池单体在电池中的位置以及各个单体电池的芯片标识信息。例如，该对应关系信息可以包括每个电池单体的芯片标识信息和位置信息。
可选地，可以在获得电池的各个电池单体的芯片标识信息后，可以按获取顺序存储，在需要使用该芯片标识信息时，则可以根据该存储顺序确定出各个芯片标识信息与各电池单体的位置信息的关系，以构建电池单体的位置信息与其芯片标识信息的对应关系信息。
可选地，该对应关系信息还可以通过各电池单体的位置信息与芯片标识信息组合形成。例如，一个电池中的电池单体按照图1所示的实例中进行排序的位序为13，且该电池单体的芯片标识信息为ID13，则该对应关系信息可以表示为13_ID13或P13_ID13。
再例如，一个电池单体位于第1个电池模组中，且该电池单体在第1个电池模组中的位序为5，且该电池单体的芯片标识信息为ID15，则该电池单体的对应关系信息可以表示为1-5_ID15或M1-5_ID15。
可选地，可以将电池单体的位置信息以及其该芯片标识信息进行绑定，以确定出其中一个电池单体的对应关系信息。例如，若一个电池单体的位置信息为P37，且该电池单体的芯片标识信息可以为ID37，则该电池单体的对应关系信息可以包括P37和ID37，在电池管理单元中存储的对应关系信息中可以通过P37查询出该电池单体的芯片标识信息为ID37，在电池管理单元中存储的对应关系信息中可以通过芯片标识信息ID37可以查询出该电池单体的位置信息为P37。
可选地，在电池管理单元获得该对应关系信息后，还可以将该对应关系信息发送给各个电池单体对应的电芯监控单元，以供各个电芯监控单元也对该对应关系信息进行存储。例如，若电池的电池管理单元损坏，需要替换新的电池管理单元，在电池管理单元投入使用之前，可以先从各个电芯监控单元中获取各个电池单体的对应关系信息。再例如，若电池的电池管理单元损坏，其记录的对应关系信息丢失，在电池管理单元投入使用之前，可以各个电芯监控单元可以先将各个电池单体的对应关系信息发送给电池管理单元，以供电池管理单元对对应关系信息进行存储。
本实施例中，通过在电池管理单元中存储各个电池单体的芯片标识信息，可以使电池管理单元能够准确地知道其管理的电池中包含的电芯监控单元，从而与其包含的电芯监控单元进行通信，也就能够更准确地获得其包含的各个电池单体的工作参数。
在一可选的实施方式中，步骤410可以包括：根据预设次序获取该电池中的该电池单体的位置信息。
示例性地，可以按照图1所示的虚线箭头的次序依次获取电池中的电池单体的位置信息。
可以在获取该电池单体的功能芯片的芯片标识信息之前，通过虚线箭头的次序获得该电池单体的位置信息；在获得该单体电池的位置信息后，获取该电池单体的功能芯片的芯片标识信息。按照图1所示的虚线箭头的次序重复执行步骤410和步骤420可以完成电池中的电池单体的位置信息的获取以及芯片标识信息的获取。
在一可选的实施方式中，步骤410可以包括：根据该电池单体的位置信息，获取该单体电池的功能芯片的芯片标识信息。
可选地，可以在确定任意一个电池单体的位置信息后，随即获取该电池单体的芯片标识信息。
可选地，也可以按照各个单体电池的位置信息，定位该电池单体的位置，以读取该位置的电池单体的功能芯片的芯片标识信息。示例性地，在获取该芯片标识信息后，可以将该芯片标识信息与电池单体的位置信息进行关联。
本实施例提供的电池可以包括多个电池模组，每个该电池模组包括多个电池单体，每个该电池模组包括多个电池单体。在此基础上，如图5所示，步骤420可以包括步骤421至步骤423。
步骤421，根据该电池单体的第一位置信息，依次获取该电池模组中的每个电池单体的芯片标识信息。
在一种实施方式中，在电池模组组装完成后，根据该电池单体的第一位置信息，依次通过扫描设备依次扫描该电池模组中的各个电池单体的芯片标识信息。
示例性地，其中一个电池模组可以包括M1行N1列电池单体为例，则该电池模组中的各电池单体的第一位置信息可以是按第一行至第M1行，每一行可以从第一列至第N1依次确定的。则可以通过扫描设备按照从第一行至第M1行，每一行可以从第一列至第N1列依次扫描该电池模组中的M1*N1个电池单体的芯片标识信息。
例如，各个电池单体的芯片标识信息可以标记在电池单体的电芯监控单元上。例如，可以通过雕刻的方式将芯片标识信息雕刻在电芯监控单元表面，以方便扫描设备扫描该芯片标识信息。
在另一种实施方式中，电池单体的第一位置信息可以在组装电池模组过程中按照电池单体的组装顺序依次确定的，则也可以按照各电池单体的组装顺序依次获取每个用于组装电池模组的电池单体的芯片标识信息。
示例性地，则可以在组装电池模组时，确定组装形成的电池模组中的各个电池单体的第一位置信息，以及采集各电池单体的芯片标识信息。
在另一种实施方式中，在电池模组组装完成后，根据该电池单体的第一位置信息，依次获取每个用于组装电池模组的电池单体的芯片标识信息。
例如，可以在每个电池模组组装完成后，再按照设定的顺序依次确定出电池模组中各电池单体的第一位置信息，也按照各电池单体的第一位置信息，依次扫描电池模组的电池单体的芯片标识信息。该设定顺序可以是第一行至第M1行，每一行都可以从第一列至第N1列依次扫描；也可以是蛇形顺序，例如，单数行可以从第一列至第N1列依次扫描，双数行可以从第N1列至第一列依次扫描。
步骤422，根据该电池模组的电池单体的芯片标识信息以及该电池单体的第一位置信息，生成模组标识。
其中，该模组标识包括该电池模组中包含的电池单体的芯片标识信息和位置信息。
示例性地，该模组标识可以包括该电池模组中所包含的全部电池单体的芯片标识信息，以及各个电池单体在电池模组中的位置信息。例如，一电池模组中的第i个电池单体的位置信息可以表示为Mx-i，其中，x表示待确定的位置，在该电池模组在电池中的位置确定后，可以确定出该待确定的位置。例如，该电池模组在整个电池中被安装在排序第四的位置，则该x的取值则可以为4。
步骤423，按照该电池模组在该电池中的第二位置信息，依次获取各个电池模组的模组标识。
可选地，在各个该电池模组组装成电池后，按照各个该电池模组在该电池中的位置，通过扫描设备依次扫描各个电池模组的模组标识。
例如，以电池模组在电池中的排序为第j位序，则该电池模组中i个电池单体的位置信息可以表示为Mj-i。
对应关系信息可以包括表征各个电池单体在电池模组中的第一位置信息以及单体电池所在的电池模组在电池中的位置的第二位置信息，以及电池单体的功能芯片的芯片标识信息。
该对应关系信息可以包括每个电池单体的位置信息与芯片标识信息的关系信息。每一个电池单体的关联信息可以由一串字符串表示，也可以通过将位置信息与芯片标识信息进行绑定呈现。
电池模组在电池中的排序为第j位序，则该电池模组中i个电池单体的位置信息可以表示为Mj-i，且该电池单体的芯片标识信息可以表示为IDji。在一个实例中，由一串字符串表示一个电池单体的关联信息，该电池单体的关联信息可以表示为Mj-i_IDji。在另一个实例中，也可以仅将位置信息Mj-i与芯片标识信息IDji进行绑定，并存储在电池管理单元中，该电池管理单元可以通过位置信息Mj-i可以查询到电池单体的芯片标识信息为IDji，该电池管理单元也可以通过电池单体的芯片标识信息IDji可以查询到电池单体的位置信息为Mj-i。
进一步地，步骤430可以包括：根据该第二位置信息以及该模组标识，确定出该电池单体的该位置信息和该芯片标识信息的对应关系信息；将该电池单体的该位置信息和该芯片标识信息的对应关系信息存入该电池的电池管理单元中，其中，该电池管理单元通过该标识信息与该功能芯片通信。
本实施例中，如果电池由多个电池模组组成，可以先形成一个中间标识模组标识，可以降 低位置信息的复杂度，还能够使各电池单体的相对位置更加清晰，从而可以使对应关系信息所表达出的电池单体的各位置关系更加准确。
每个电池单体除了唯一对应有其包含的电芯监控单元的芯片标识信息，还可以包括记录电池单体生产信息、电池单体特性信息的单体标识信息。因此在存入电池管理单元的对应关系信息中还可以包括单体标识信息。在步骤410之前，电池编码方法还可以包括：在每个电池单体完成制作后，获取每个电池单体的单体标识信息和芯片标识信息，并将每个电池单体的该单体标识信息与该芯片标识信息进行关联存储。
步骤430可以包括：将该电池单体的该位置信息、该芯片标识信息以及该单体标识信息的对应关系信息存入该电池的电池管理单元中。
每个电芯监控单元与每个单体电池单体在生产电池单体进行绑定，在每个电池单体在下线后，可以将芯片标识信息作为电池单体的标识。
可选地，可以在将电芯监控单元装配到电池单体上，可以实现电芯监控单元与电池单体的物理绑定时，使用扫码设备扫描单体标识信息与芯片标识信息，并将单体标识信息与芯片标识信息进行绑定。
因此，在获得任意一个电池单体的单体标识信息可以通过预先关联存储的数据中确定出电池单体的芯片标识信息，在获得任意一个电池单体的芯片标识信息可以通过预先关联存储的数据中确定出电池单体的单体标识信息。
在一个实例中，电池模组在电池中的排序为第j位序，则该电池模组中i个电池单体的位置信息可以表示为Mj-i，且该电池单体的芯片标识信息可以表示为IDji，电池单体的单体标识信息可以为ID-ji。在一个实例中，由一串字符串表示一个电池单体的关联信息，该电池单体的关联信息可以表示为Mj-i_IDji_ID-ji。
在另一实例中，位置信息为P37的电池单体的芯片标识信息可以为ID37，且该电池单体的单体标识信息可以为ID-37，则该电池单体的对应关系信息可以表示为P37_ID37_ID-37。
通过上述电池编码方法的实现过程实现了首次装配电池时的组网过程，即电池管理单元在发送信息时，只和自己存储列表已存在芯片标识信息的电芯监控单元通信，不和不存在芯片标识信息的电芯监控单元通信，从而可以避免该电池与其它电池或者待组装的电池单体的电芯监控单元形成通信。
通过上述编码方法，该做法的好处为：每个电池中的电池管理单元都有自己需要通信的电芯监控单元的芯片标识信息，后续根据芯片标识信息及其对应的位置信息可以快速定位到异常电池单体位置。
在上述的电池的应用过程中只与自己列表中存在的芯片标识信息的电芯监控单元通信，相当于身份认证，提高了数据通信的可靠性，避免后续黑客伪装电芯监控单元信息，影响通信，窃取数据(增加译码过程)；另外，每个电芯监控单元存储自己的位置标识，提供了一个备份，当电池管理单元出现了异常，丢失了电芯监控单元的芯片标识信息的列表信息，使用新的电池管理单元后，可以将从各个电芯监控单元中将数据读回，避免需要重新扫码确认。
下面通过两个实例来描述电池编码方法的流程：
若直接将电池单体组装成电池，则可以通过以下流程进行电池的编码：
每个电芯监控单元上的电池单体监控芯片需要有自己的唯一芯片标识信息，该唯一的芯片标识信息可以跟随其数据发送(即电芯监控单元发送的每一帧数据都有芯片标识信息)，该唯一的芯片标识信息可以通过二维码标识标记在电池单体的电芯监控单元的芯片外壳上。
将电芯监控单元与单体电池单体绑定过程：每个电池单体在下线过程后，都会有自己的唯一的单体标识信息，该单体标识信息可以是二维码。将电芯监控单元装配到单体电池单体时，使用扫码设备扫描电池单体的二维码与芯片的二维码，实现两者电芯监控单元与单体电池单体在软件上绑定。并且将电芯监控单元的芯片集成在单体电池单体上，实现了物理上的绑定。因此，可以以电 芯监控单元的唯一芯片标识信息作为整体电池单体的标识。
将电池单体组成电池后，使用扫码设备按顺序扫描电池中每个电池单体的二维码，例如，可以从BAT-开始为第一个；
通过上述操作流程可以得到了对应关系：例P1_ID1_ID-1，该电池的第1个电池单体，对应的电芯监控单元的芯片标识信息为ID1，对应的电池单体的单体标识信息为ID-1；
因此，通过每个电池单体发送数据的芯片标识信息，我们就可以解析出该电池单体在电池中的物理位置。
若需要先将电池单体组装成电池模组，然后再将电池模组组装成电池，则可以通过以下流程进行电池的编码：
将电芯监控单元与单体电池单体绑定过程：每个电池单体在下线过程后，都会有自己的唯一的单体标识信息，该单体标识信息可以是二维码。将电芯监控单元装配到单体电池单体时，使用扫码设备扫描电池单体的二维码与芯片的二维码，实现两者电芯监控单元与单体电池单体在软件上绑定。并且将电芯监控单元的芯片集成在单体电池单体上，实现了物理上的绑定。因此，可以以电芯监控单元的唯一芯片标识信息作为整体电池单体的标识。
将电池单体组成电池模组后，使用扫码设备按电池模组负到正，逐个扫描电芯监控单元的二维码信息，然后生成模组二维码。该二维码需要包含电芯监控单元的芯片标识信息的顺序。例：Mx-1，Mx-2，x为预留位置，可标定为具体代表电池模组的顺序的符号，比如1，2或者Ⅰ，Ⅱ；
将该电池模组装配成电池后，使用扫码设备按顺序扫描每个模组二维码(通常从BAT-开始为第一个)。并将模组顺序信息写入预留的标定位，即可形成：M1-1，M1-2，M2-2等。即可以形成电池模组的顺序信息与电池单体的在电池模组中的顺序信息，并相互绑定；
通过上述方式可以得到了对应关系：例M1-1_ID1_ID-1，即可以标识1号模组的第一个电池单体，对应的电芯监控单元的ID号为ID1，对应的电池单体的ID号为ID-1；
然后，上位机完成上述处理过程后，可以将对应信息发送给该电池的电池管理单元，电池管理单元将数据存储在存储器中，并通过无线管理单元，将数据发送个每个电芯监控单元，电芯监控单元将与自己芯片标识信息一致的位置信息写入自己的存储器，该位置存储位置受保护；
同时，该过程也实现了电池在首次装配时的组网过程，即电池管理单元在发送信息时，只和自己存储列表已存在芯片标识信息的电芯监控单元通信，不与列表中不存在芯片标识信息的电芯监控单元通信，避免了该电池与其它电池或者待组装的电池单体形成通信，提高电池管理单元工作的有效性。
