Description

一种通信方法、装置及系统 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法、装置及系统。
背景技术
为了对电池的全生命周期(例如，电池生产、存储、运输、回收等各个环节)进行管理，通常会设置电池管理系统(battery management system，BMS)。
随着电池的数量增多，电池中设置的终端节点的数量也相应增多。因此，如何提升BMS中的管理节点的通信容量，以BMS满足对大量电池的状态进行管理的需求，是本申请亟需解决的问题。
发明内容
本申请提供一种通信方法、装置及系统，用以提升电池管理系统(battery management system，BMS)中管理节点的通信容量，以满足BMS对大量电池的状态进行管理的需求。
第一方面，本申请实施例提供一种通信方法，该方法可以应用于管理节点，也可以应用于管理节点中的部件(例如处理器、芯片、或芯片系统等)，该方法包括：在第一时间窗内，与至少一个第一节点建立通信连接，至少一个第一节点属于第一分组；在第一时间窗内，接收至少一个第一节点关联的电池信息；在第二时间窗内，与至少一个第二节点建立通信连接，至少一个第二节点属于第二分组；在第二时间窗内，接收至少一个第二节点关联的电池信息；其中，第一时间窗与第二时间窗不存在重叠的时间资源，和/或，第一分组和第二分组中不存在相同的节点。
可以理解的是，本申请实施例中“第一时间窗”或“第二时间窗”可以通过以下一项或多项信息定义：起始时间、起始时间的时间偏移量、截止时间、截止时间的时间偏移量、周期、窗长。以及，本申请实施例中“第一时间窗与第二时间窗不存在重叠的时间资源”，可以理解为第一时间窗和第二时间窗对应的时间资源可以是连续的，或者是存在预设间隔的，本申请实施例不作具体的限制。
在本申请实施例中，管理节点可以将其管理的节点(即至少一个第一节点和至少一个第一节点)进行分组管理，并且在每个时间窗内与一个分组中的节点建立通信连接，以及接收该分组中的节点关联的电池信息，从而实现对该分组中的节点关联的电池的管理。如此，通过对管理节点的通信资源合理分配，可以有效减少管理节点因资源受限无法对大量节点进行管理的情况，从而有效提升BMS中管理节点的通信容量，满足BMS对大量电池的状态进行管理的需求。
在一种可能的实施方式中，上述至少一个第一节点关联的电池信息可以包括电池的电压信息、电流信息、温度信息、湿度信息或形变信息中的一项或多项。在该实施方式中，至少一个第一节点关联的电池信息包括电池的多种信息，使得BMS可以从多个维度对至少一个第一节点关联的电池的状态进行监控。
在一种可能的实施方式中，上述第一时间窗对应第一资源，第二时间窗对应第二资源；相应的，在第一时间窗内，接收至少一个第一节点关联的电池信息，包括：在第一资源上， 接收至少一个第一节点关联的电池信息；在第二时间窗内，接收至少一个第二节点关联的电池信息，包括：在第二资源上，接收至少一个第二节点关联的电池信息。
可以理解的是，第一资源或第二资源包括但不限于时域、频域、空域或功率域等资源，本申请实施例不作限制。
在该实施方式中，通过为第一时间窗设置第一资源，以及为第二时间窗设置第二资源，使得管理节点在每个时间窗内可以通过该时间窗对应的特定资源，接收该分组内的节点关联的电池信息。
在一种可能的实施方式中，所述第一分组与第一时间窗对应；和/或，上述第二分组与第二时间窗对应。本申请实施例中“第一时间窗对应第一分组”可以理解为管理节点为第一分组设置了第一时间窗，进而第一分组中的第一节点可以在第一时间窗内与管理节点建立通信连接，以及本申请实施例中“第二时间窗对应第二分组”可以理解为管理节点为第二分组设置了第二时间窗，进而第二分组中的第二节点可以在第二时间窗内与管理节点建立通信连接。在该实施方式中，通过为不同的分组设定不同的时间窗，使得管理节点在不同的时间窗内，可以对不同分组中的节点进行管理，从而使得管理节点的资源(例如通信资源)合理分配。
在一种可能的实施方式中，上述第一分组包括第一子分组，上述方法还包括：在满足第一条件时，对第一子分组中的第一节点执行第一操作；其中，第一条件包括以下中一个或多个：第一时间窗的截止时间到达；第一子分组中的第一节点的服务质量QoS业务中无低时延传输要求；接收到释放请求指示信息，释放请求指示信息用于指示释放第一子分组中的第一节点对应的通信连接；第一子分组中的第一节点处于低功耗模式；第一子分组中的第一节点的温度超出第一预设值；第一子分组中与管理节点建立通信连接的第一节点的数量超出第二预设值。
其中，上述第一操作包括但不限于以下任一项：释放第一子分组中的第一节点对应的通信连接；去激活第一子分组中的第一节点；向第一子分组中的第一节点发送第一信息，第一信息用于指示第一子分组中的第一节点进入低功耗模式。
可以理解的是，本申请实施例中，“低功耗模式”是指第一节点处于节能模式，周期性地与管理节点建立通信连接。示例性的，低功耗模式的周期为30ms，则第一节点在前20ms内与管理节点建立通信连接，在后10ms内不与管理节点建立通信连接。
在该实施方式中，第一分组包括第一子分组，管理节点可以在满足第一条件时，对第一子分组中的第一节点执行相应的操作(例如，释放通信连接、去激活等)，可以有效减少BMS的资源开销。
在一种可能的实施方式中，上述第一分组中还包括第二子分组，第一子分组和第二子分组不存在相同的第一节点；上述方法还包括：在第一时间窗结束后的第一时长内，与第二子分组中的第一节点保持通信连接；和/或，在第一时间窗内，与第二子分组中的第一节点建立通信连接的时间不晚于与第一子分组中的第一节点建立通信连接的时间。
可以理解的是，在一些实施例中，“第二子分组中的第一节点”可以是用于管理一个或多个子节点的节点。例如，第二子分组中的第一节点可以接收至少一个子节点关联的电池信息，并将该电池信息上报至管理节点，如此使得管理节点可以获取更多节点关联的电池信息，进一步使得BMS中管理节点的通信容量最大化。因此，在该实施方式中，管理节点在第一时间窗结束后的第一时长内，与第二子分组中的第一节点保持通信连接；和/ 或，在第一时间窗内，与第二子分组中的第一节点建立通信连接的时间不晚于与第一子分组中的第一节点建立通信连接的时间，可以实现对大量的节点关联的电池进行管理。
在一种可能的实施方式中，若上述至少一个第一节点关联的电池信息中的温度信息指示至少一个第一节点关联的电池的温度超出第三预设值，则管理节点可以向至少一个第一节点发送第二信息，第二信息用于指示对至少一个第一节点关联的电池进行第一处理。其中，第一处理包括但不限于放电、断电、充电或停止充电中的一项或多项。
类似的，若上述至少一个第一节点关联的电池信息中的电压信息指示至少一个第一节点关联的电池的电压超出第四预设值，管理节点也可以向至少一个第一节点发送第二信息，第二信息用于指示对至少一个第一节点关联的电池进行第一处理。类似的，若上述至少一个第一节点关联的电池信息中的电流信息指示至少一个第一节点关联的电池的电流超出第五预设值，管理节点也可以向至少一个第一节点发送第二信息，第二信息用于指示对至少一个第一节点关联的电池进行第一处理。类似的，若上述第一分组中的第一节点关联的电池信息中的湿度信息指示第一分组中的第一节点关联的电池的湿度超出第六预设值，管理节点也可以向第一分组中的第一节点发送第二信息，第二信息用于指示对第一分组中的第一节点关联的电池进行第一处理。类似的，若上述至少一个第一节点关联的电池信息中的形变信息指示至少一个第一节点关联的电池发生形变，管理节点也可以向至少一个第一节点发送第二信息，第二信息用于指示对至少一个第一节点关联的电池进行第二处理；其中，第二处理包括但不限于断电或停止充电中的任一项。
在该实施方式中，在至少一个节点关联的电池信息的出现异常时，管理节点可以指示对至少一个第一节点关联的电池进行相应的处理(例如，第一处理和第二处理)。如此，有效提升电池的使用安全性，从而可以有效延长电池的使用寿命。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)电池管理系统(battery management system，BMS)，用于保护电池组的安全使用，在电池组充放电使用过程中，保障安全的同时，延长电池组的使用寿命。电池管理系统提供了电池管理功能，电池管理功能包括但不限于监控电池的状态(例如，电池的电压、电流、温度或形变)、计算电池的充电水平和容量、控制电池的充电和放电和通信功能。其中，电池管理系统中设置了管理设备和多个终端设备，管理设备和终端设备之间可以进行通信，以传递电池的信息。
2)管理设备，BMS中与设置于电池中的终端设备进行信息交互的终端设备，下文也称作“管理节点”。管理设备与设置于电池中的终端设备共同实现BMS的通信功能。例如，管理设备可以接收终端设备关联的电池信息，以及下发相应的控制信息。在一些可能的实施例中，管理设备还可以将设置于电池中的终端设备进行分组管理。
3)分组，在本申请实施例中是指管理节点将设置于电池中的终端设备进行分组管理形成的分组，例如，第一分组和第二分组。
4)时间窗，在本申请实施例中是指管理节点对其提供的资源进行分时使用形成的预设时长，该预设时长包括截止时间、起始时间、起始时间对应的偏移量、截止时间对应的偏移量、窗长和周期。例如第一时间窗和应第二时间窗。
5)第一节点，在本申请实施例中是指第一分组中的节点。
6)第二节点，在本申请实施例中是指第二分组中的节点。
7)电芯，电芯作为电池的一个组成部分。可选的，电池中还包括保护电路板。保护电路板是指对电芯起保护作用的集成电路板。保护电路板可以包括保护芯片、金属氧化物场效应晶体管(metal oxide semiconductor，MOS)、电阻、电容、或印制电路板(printed circuit board，PCB)中的至少一项。保护电路板可以用于控制电芯进行充电、放电、或断电等处理。在本申请的一些实施例中，电池中的终端设备关联一个或多个电芯，因此该终端设备向管理设备上报的电池信息为一个或多个电芯的信息。在另一些可能的实施例中，电池中的终端设备关联一个或多个电芯和保护电路板，因此该终端设备向管理设备上报的电池信息包括一个或多个电芯的信息和保护电路板的信息。以及，在另一些可能的实施例中，电池中的终端设备关联保护电路板，因此该终端设备向管理设备上报的电池信息包括保护电路板的信息。
8)电池模组，当多个电芯被同一个外壳框架封装在一起，通过统一的边界与外部进行联系时，这就组成了一个电池模组。也就是说，一个电池模组中包括多个电芯。本申请实施例中，一个电池可以包括一个或多个电池模组。在本申请的一些实施例中，电池中的终端设备设置于电池模组中，因此电池中终端设备向管理设备上报的电池信息为电池模组的信息。当该终端设备关联一个电池模组时，该终端设备可以用于上报一个电池模组的信息，因此电池中终端设备向管理设备上报的电池信息为一个电池模组中电芯的信息；当终端设备关联多个电池模组时，该终端设备可以用于在同一时刻上报多个电池模组的信息，因此电池中终端设备向管理设备上报的电池信息为多个电池模组中电芯的信息。如此，终端设备用于上报一个或多个电池模组中电芯的信息，可以有效减少BMS中终端节点的数量。
9)“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一信息和第二信息，只是为了区分不同的信息，而并不是表示这两种信息的内容、优先级、发送顺序或者重要程度等的不同。
如上介绍了本申请实施例涉及的一些概念，下面介绍本申请实施例的技术特征。
为了提升BMS中的管理节点的中管理节点的通信容量，以满足BMS对大量电池的状态进行管理的需求。本申请实施例提供一种通信方法，该方法可以应用于管理节点，该方法包括：在第一时间窗内，与至少一个第一节点建立通信连接，至少一个第一节点属于第一分组；在第一时间窗内，接收至少一个第一节点关联的电池信息；在第二时间窗内，与至少一个第二节点建立通信连接，至少一个第二节点属于第二分组；在第二时间窗内，接 收至少一个第二节点关联的电池信息；其中，第一时间窗与第二时间窗不存在重叠的时间资源，和/或，第一分组和第二分组中不存在相同的节点。如此，管理节点可以将其管理的节点(即至少一个第一节点和至少一个第一节点)进行分组管理，并且在每个时间窗内与一个分组中的节点建立通信连接，以及接收该分组中的节点关联的电池信息，从而实现对该分组中的节点关联的电池的管理。如此，对管理节点的通信资源合理分配，可以有效减少管理节点因资源受限无法对大量节点进行管理的情况，从而有效提升BMS中管理节点的通信容量，满足BMS对大量电池的状态进行管理的需求。
下面介绍本申请适用的系统架构。
请参见图1A，图1A示出了本申请实施例适用的一种可能的系统的架构示意图，该系统包括管理节点、节点1、节点2、节点3、节点4、节点5和节点6。
其中，节点1、节点2和节点3属于第一分组，节点4、节点5和节点6属于第二分组，第一分组对应第一时间窗，第二分组对应第二时间窗。相应的，管理节点可以在第一时间窗内，与节点1、节点2、节点3建立通信连接，并在所述第一时间窗内，接收节点1、节点2、节点3关联的电池信息；以及，管理节点可以在第二时间窗内，与节点4、节点5和节点6建立通信连接，并在所述第二时间窗内，接收节点4、节点5和节点6关联的电池信息。如此，对管理节点的通信资源合理分配，可以有效减少管理节点因资源受限无法对大量节点进行管理的情况，从而有效提升BMS中管理节点的通信容量，满足BMS对大量电池的状态进行管理的需求。
可以理解的是，上述系统中终端节点的分组是以第一分组和第二分组为例，并非限定，在其他可能的实施例中，系统中终端节点的分组可以更多或更少。
进一步的，上述管理节点还可以将第一分组划分为第一子分组和第二子分组。在本申请实施例中“第二子分组中的第一节点”可以是用于管理一个或多个子节点的节点。例如，第二子分组中的第一节点可以接收至少一个子节点关联的电池信息，并将该电池信息上报至管理节点，如此使得管理节点可以获取更多节点关联的电池信息，进一步使得BMS中管理节点的通信容量最大化。因此，管理节点在第一时间窗结束后的第一时长内，与第二子分组中的第一节点保持通信连接；和/或，在第一时间窗内，与第二子分组中的第一节点建立通信连接的时间不晚于与第一子分组中的第一节点建立通信连接的时间，可以实现对大量的节点关联的电池进行管理。
示例性的，请再参见图1B，图1B示出了本申请实施例适用的另一种系统的架构示意图。在图1B中，管理节点管理的第一分组中的节点包括节点1、节点2、节点3、节点4、节点5、节点6和节点7。其中，节点1、节点2和节点3属于第一子分组，节点4、节点5、节点6和节点7属于第二子分组。在第一时间窗结束后的第一时长内，与节点4、节点5、节点6和节点7保持通信连接；和/或，在第一时间窗内，与节点4、节点5、节点6和节点7建立通信连接的时间不晚于与节点1、节点2和节点3建立通信连接的时间。
第二子分组中的每个节点还可以用于管理其他的节点，将其他节点关联的电池信息上传至管理节点。例如，节点4可以管理节点8、节点9和节点10，将节点8、节点9和节点10关联的电池信息上报至管理节点。例如，节点5可以管理节点11和节点12，将节点11和节点12关联的电池信息上报至管理节点。例如，节点6可以管理节点13、节点14和节点15，将节点13、节点14和节点15关联的电池信息上报至管理节点。例如节点7 可以管理节点16、节点17和节点18，将节点16、节点17和节点18关联的电池信息上报至管理节点。如此，管理节点可以实现同时对大量的节点关联的电池进行管理。

类似的，节点2在第一时间窗内和管理节点建立通信连接，从板3中的采集芯片可以采集模组m-模组n的信息，进而节点2通过从板3中的采集芯片获取到模组m-模组n的信息，可以将模组m-模组n中电芯的信息上报至管理节点。

类似的，第二分组中的第二节点关联的电池信息包括但不限于电池的电压信息、电流信息、温度信息、形变信息或者湿度信息中的一项或多项。因此，BMS可以从多个维度对第二分组中的第二节点关联的电池的状态进行监控。
在第二分组中的第二节点关联的电池信息异常(例如，电池的电压信息、电流信息、温度信息、形变信息或者湿度信息中的至少一项异常)时，管理节点可以执行相应操作，该操作与在第一分组中的第一节点关联的电池信息异常时，管理节点执行的操作类似，请参见前文的描述，只需将“第一分组中的第一节点”替换为“第二分组中的第二节点”。
在一种可能的实施方式中，在满足第一条件时，管理节点还可以对第一分组中的第一节点执行第一操作。
本申请实施例中，上述第一条件包括以下中一个或多个：第一时间窗的截止时间到达；第一分组中的第一节点的服务质量QoS业务中无低时延传输要求；管理节点接收到释放请求指示信息，该释放请求指示信息用于指示释放第一分组中的第一节点对应的通信连接；第一分组中的第一节点处于低功耗模式；第一分组中的第一节点的温度超出第一预设值；第一分组中与管理节点建立通信连接的第一节点的数量超出第二预设值。本申请实施例中，上述第一操作可以包括以下任一项：释放第一分组中的第一节点对应的通信连接；去激活第一分组中的第一节点；向第一分组中的第一节点发送第一信息，该第一信息用于指示第一分组中的第一节点进入低功耗模式。其中，可以是去激活第一分组中的全部或部分第一节点。
可以理解的是，本申请实施例中，“低功耗模式”是指第一节点处于节能模式，周期性地与管理节点建立通信连接。示例性的，低功耗模式的周期为30ms，则第一节点在前20ms内与管理节点建立通信连接，在后10ms内不与管理节点建立通信连接。

在图3所示的实施例中，管理节点可以将其管理的节点(即至少一个第一节点和至少一个第一节点)进行分组管理，并且在每个时间窗内与一个分组中的节点建立通信连接，以及接收该分组中的节点关联的电池信息，从而实现对该分组中的节点关联的电池的管理。如此，对管理节点的通信资源合理分配，可以有效减少管理节点因资源受限无法对大量节点进行管理的情况，从而有效提升BMS中管理节点的通信容量，满足BMS对大量电池的状态进行管理的需求。
需要说明的，在一些可能的实施例中，上述第一分组可以包括第一子分组和/或第二子分组，其中，第一子分组和第二子分组不存在相同的第一节点；第二子分组中的第一节点是用于管理一个或多个子节点的节点，第二子分组中的第一节点可以接收至少一个子节点关联的电池信息，并将该电池信息上报至管理节点，如此使得管理节点可以获取更多节点关联的电池信息，进一步使得BMS中管理节点的通信容量最大化。其中，第二子分组中的第一节点例如可以是图1B所示的节点4、节点5、节点6和节点7，子节点例如可以是图1B所示的节点8、节点9和节点10。
示例性的，请参见图5，图5示出了本申请实施例中提供的另一种通信方法的流程示意图，该方法适用于图1B所示的系统架构，该方法包括以下步骤：

示例2，第一条件以管理节点接收到释放请求指示信息为例，第一操作以释放第一子分组中的第一节点对应的通信连接为例，在管理节点接收到释放请求指示信息时，管理节点释放第一子分组中的第一节点对应的通信连接。

示例4，第一条件以第一子分组中的第一节点的温度超出第一预设值为例，第一操作以向第一子分组中的第一节点发送第一信息为例，在第一子分组中的第一节点的温度超出第一预设值时，向第一子分组中的第一节点发送第一信息，该第一信息用于指示第一子分组中的第一节点进入低功耗模式。
示例5，第一条件以第一子分组中与管理节点建立通信连接的第一节点的数量超出第二预设值和部分第一节点无低时延传输要求为例，第一操作以释放第一子分组中的第一节点对应的通信连接为例，在第一子分组中与管理节点建立通信连接的第一节点的数量超出第二预设值时，释放第一子分组中的部分第一节点对应的通信连接。例如，可以去激活无低时延传输要求的第一节点。
示例6，第一条件以第一子分组中与管理节点建立通信连接的第一节点的数量超出第二预设值和部分第一节点无低时延传输要求为例，第一操作以去激活第一子分组中的第一节点为例，在第一子分组中与管理节点建立通信连接的第一节点的数量超出第二预设值时，去激活第一子分组中的部分第一节点。
示例7，第一条件以第一子分组中的第一节点的QoS业务中无低时延传输要求为例，第一操作以向第一子分组中的第一节点发送第一信息为例，在第一子分组中的第一节点的QoS业务中无低时延传输要求时，向第一子分组中的第一节点发送第一信息，该第一信息用于指示第一子分组中的第一节点进入低功耗模式。
在该实施方式中，管理节点可以在满足第一条件时，对第一子分组中的第一节点执行相应的操作(例如，释放通信连接、去激活等)，可以有效减少BMS的资源浪费。
在图5所示实施例中，由于第二子分组中的第一节点可以用于管理至少一个子节点，在第一时间窗内，管理节点与第二子分组中的第一节点建立通信连接的时间不晚于与第一子分组中的第一节点建立通信连接的时间，如此使得管理节点可以获取更多节点关联的电池信息，进一步使得BMS中管理节点的通信容量最大化。
在一种可能的实施方式中，若第一分组中包括第二子分组，管理节点在第一时间窗结束后的第一时长内，仍然与第二子分组中的第一节点保持通信连接。如此，使得管理节点可以持续获取第二子分组中的第一节点关联的电池信息，并且第二子分组中的第一节点可以管理至少一个子节点，使得管理节点可以获取更多的节点关联的电池信息，进一步使得BMS中管理节点的通信容量最大化。该实施方式和图5所示的实施例可以结合使用或者单独使用，本申请实施例不作限制。
需要说明的是，每个分组对应的时间窗内还可以对应预留资源，进而管理节点在每个分组对应的时间窗内可以通过预留资源与其他分组中的节点建立连接。其中，预留资源包括但不限于时域、频域、空域和功率域等资源，本申请实施例不作具体的限制。
如图6所示，第一分组包括节点1、节点2、节点3和节点4，第二分组包括节点5、节点6、节点7和节点8，第三分组包括节点9、节点10、节点11和节点12；由于第一时间窗对应预留资源，第一时间窗调度的节点为节点1、节点5和节点9，因此在第一分组对应的第一时间窗内，管理节点可以通过上述第一资源与节点1建立通信连接，以及通过预留资源与节点5和节点9建立通信连接。类似的，第二时间窗对应预留资源，第二时间窗调度的节点为节点2、节点3、节点6、节点7和节点10，因此在第二分组对应的第二时间窗内，管理节点可以通过上述第二资源与节点2、节点3建立通信连接，以及通过预留资源与节点6、节点7和节点10建立通信连接。第三时间窗对应预留资源，第三时间窗调度的节点为节点4、节点8、节点11和节点12，因此在第三分组对应的第三时间窗内，管理节点可以通过第三时间窗对应的第三资源与节点11和节点12建立通信连接，以及通过预留资源与节点4和节点8建立通信连接。其中，第三资源包括但不限于时域、频域、空域和功率域等资源，本申请实施例不作具体的限制。
如此，管理节点在每个分组对应的时间窗内可以通过预留资源与其他分组中的节点建立通信连接，便于其他分组中的节点上报其关联的电池信息，尤其是在其他分组中的节点关联的电池出现异常(例如，温度超出预设值、电压超出预设值、电流超出预设值、发生形变等)时，便于对其他分组中的关联的电池采取相应的安全措施。
为了便于理解，下面以第一时间窗内的调度的节点为例，介绍管理节点通过预留资源与其他分组中的节点建立连接的过程。
示例性的，请参见图7，图7示出了本申请实施例中提供的另一种通信方法的流程示意图，该方法包括以下步骤：
S701、管理节点在第一时间窗内，通过第一资源与第一分组中的第一节点建立通信连接。
相应的，管理节点可以在第一时间窗内，通过第一资源接收第一分组中的第一节点关联的电池信息。
S702、管理节点在第一时间窗内，通过预留资源与至少一个第三节点建立通信连接。
可以理解的是，至少一个第三节点不属于第一分组，可以是其他分组中的一个或多个节点。
示例性的，请参见继续图6，至少一个第三节点例如可以是第二分组中的节点5，或者，可以是第三分组中的节点9，或者，可以是第二分组中的节点5和第三分组中的节点9。
其中，至少一个第三节点的优先级高于第一分组中第一节点的优先级，该优先级可以通过待上报信息的紧急程度或服务质量(quality of service，QoS)要求中的至少一项表征。
可以理解的是，至少一个第三节点的优先级是动态变化的。例如，节点1在第一时刻的待上报信息的紧急程度较高，则节点1的优先级为高；又例如，节点1在第二时刻的待上报信息的紧急程度较低，则节点1的优先级为低。
在一些可选的设计中，至少一个第三节点中的每个第三节点可以用于管理子节点，即每个第三节点可以向管理节点上报该第三节点管理的子节点所关联的电池信息，则至少一个第三节点设置为一个分组，这个分组的优先级高于BMS中其他终端节点的分组(例如，第一分组和第二分组)。
在本申请实施例中，“待上报信息的紧急程度”可以是通过判断至少一个第三节点关联的电池信息中的电压信息、电流信息、温度信息、湿度信息或形变信息中的至少一项是否存在异常，来确定的。例如，至少一个第三节点关联的电池信息中的电压信息异常，第一分组中第一节点的电池信息中的电压信息无异常，则确定至少一个第三节点待上报信息的紧急程度高于第一分组中第一节点待上报信息的紧急程度，相应的，至少一个第三节点的优先级高于第一分组中第一节点的优先级。例如，至少一个第三节点关联的电池信息中的电流信息异常，第一分组中第一节点的电池信息中的电流信息无异常，则确定至少一个第三节点待上报信息的紧急程度高于第一分组中第一节点待上报信息的紧急程度，相应的，至少一个第三节点的优先级高于第一分组中第一节点的优先级。例如，至少一个第三节点关联的电池信息中的温度信息异常，第一分组中第一节点的电池信息中的温度信息无异常，则确定至少一个第三节点待上报信息的紧急程度高于第一分组中第一节点待上报信息的紧急程度，相应的，至少一个第三节点的优先级高于第一分组中第一节点的优先级。例如，至少一个第三节点关联的电池信息中的湿度信息异常，第一分组中第一节点的电池信息中的湿度信息无异常，则确定至少一个第三节点待上报信息的紧急程度高于第一分组中第一节点待上报信息的紧急程度，相应的，至少一个第三节点的优先级高于第一分组中第一节点的优先级。例如，至少一个第三节点关联的电池信息中的形变信息异常，第一分组中第一节点的电池信息中的形变信息无异常，则确定至少一个第三节点待上报信息的紧急程度高于第一分组中第一节点待上报信息的紧急程度，相应的，至少一个第三节点的优先级高于第一分组中第一节点的优先级。
在本申请实施例中，QoS要求用于表征至少一个第三节点的QoS策略，QoS策略例如可以是保障速率、传输时延、时延抖动、丢包率、可靠性要求或业务类型(高吞吐、低时 延传输等)中的至少一项。若至少一个第三节点的QoS要求中包括低时延传输要求，则管理节点确定至少一个第三节点的优先级较高，为至少一个第三节点建立通信连接。或者，至少一个第三节点的QoS要求中包括低时延传输要求和待上报信息的紧急程度较高时，则管理节点确定至少一个第三节点的优先级较高，为至少一个第三节点建立通信连接。
在图7所示的实施例中，通过第一时间窗内的预留资源，管理节点可以在第一时间窗内与其他分组中的待上报信息紧急程度较高的节点和/或存在QoS要求的节点建立通信连接，从而使得这些节点关联的电池的紧急信息可以及时上报，或者，可以有效满足这些节点的QoS要求(例如低时延传输要求)。
在一种可能的实施方式中，上述第一时间窗是根据管理节点与第一分组中第一节点之间的信道质量、QoS要求、或第一分组中第一节点的数量中的至少一项确定的。例如，第一分组中第一节点的数量越多，管理节点与第一分组中第一节点之间的信道质量越好，则第一时间窗的窗长越短。例如，第一分组中第一节点的数量越多，管理节点与第一分组中第一节点之间的信道质量较差，则第一时间窗的窗长越长。例如，第一分组中第一节点的数量越多，管理节点与第一分组中第一节点之间的信道质量越好，则第一时间窗的窗长越短。类似的，上述第二时间窗是根据管理节点与第二分组中的第二节点之间的信道质量、QoS要求、或第二分组中第二节点的数量中的至少一项确定的。在该实施方式中，第一时间窗和第二时间窗可以根据一种或多种因素灵活确定。
请参见图8，在一种可能的实施方式中，BMS中还可以设置节能策略，节能策略例如可以是非连续接收机制(discontinuous reception，DRX)(即管理节点可以周期性地接收终端节点上报的电池信息)，其中，BMS为非连续接收机制配置了第一周期T，第一周期T包括唤醒时间窗和休眠时间窗。在唤醒时间窗内，管理节点和设置于电池中的终端节点均处于唤醒状态，管理节点可以与终端节点建立通信连接。在休眠时间窗内，终端节点处于休眠模式。本申请实施例中“休眠模式”可以理解为管理节点与终端节点不建立通信连接，或者，终端节点处于低功耗模式。如此，通过在第一周期内设置唤醒时间窗和休眠时间窗，使得管理节点可以周期性地与终端节点建立通信连接，从而有利于终端节点以及管理节点的功率消耗。
示例性的，唤醒时间窗例如可以是前文所述的第一时间窗和第二时间窗，相应的，在唤醒时间窗内，管理节点可以与第一分组中的第一节点和/或第二分组中的第二节点(即终端节点)建立通信连接。类似的，在休眠时间窗内，第一分组中的第一节点和第二分组中的第二节点处于休眠模式。
可以理解的是，上述第一周期T可以是灵活配置的，本申请实施例不作具体的限制。
在一些可能的实施例中，管理节点还可以基于BMS中终端节点的标识信息，将BMS中终端节点分为至少一个分组。其中，至少一个分组中的每个分组可以对应一个时间窗，例如第一分组对应第一时间窗。
可以理解的是，“至少一个分组”是管理节点将设置于电池中的终端节点进行分组管理形成的分组，例如，第一分组和第二分组。可选的，至少一个分组中的每个分组中对应的终端节点可以是动态变化的。以及每个分组中终端节点的数量可以相同或不同。不同的分组中的终端节点可以部分相同或全部不同。
在一种可能的实施方式，若BMS中配置了节能策略，节能策略例如可以是上述非连 续接收机制，且BMS为非连续接收机制配置了第一周期T，则管理节点可以根据每个时间窗对应的时间资源和第一周期T，确定第一周期T中的时间窗个数，该时间窗个数即BMS中至少一个分组的分组数目。进一步的，管理节点还可以根据BMS中终端节点的标识信息，确定每个时间窗的起始时刻。
其中，BMS中终端节点的标识信息可以是管理节点预先存储的，也可以是管理节点后续获取的。其中，管理节点获取BMS中终端节点的标识信息，有多种实现方式，包括但不限于以下实施方式：
方式1，管理节点接收BMS中终端节点的广播信息，所述广播信息用于指示BMS中终端节点的标识信息。
示例性的，管理节点接收第一分组中的第一节点的广播信息，该广播信息用于指示第一分组中的第一节点的标识信息。
方式2，管理节点接收BMS中终端节点的单播信息，所述单播信息用于指示BMS中终端节点的标识信息。
可以理解的是，管理节点接收BMS中终端节点的单播信息之前，管理节点需要与BMS中终端节点建立通信连接。
示例性的，管理节点接收第一分组中的第一节点的单播信息，所述单播信息用于指示第一分组中的第一节点的标识信息。
方式3，管理节点通过内存获取BMS中终端节点的标识信息。
示例性的，管理节点通过内存获取第一分组中的第一节点的标识信息。
其中，BMS中终端节点的标识信息可以是技术人员通过上位机，写卡器，管脚，串口等方式写入管理节点的内存，进而管理节点通过内存获取BMS中终端节点的标识信息。
以上三种实施方式可以单独使用或者结合使用，本申请实施例不作具体的限制。
在本申请实施例中，BMS中节点的标识信息包括但不限于以下任一种：媒体接入层标识、层2链路标识、国际移动设备标识(international mobile equipment identity，IMEI)、临时移动用户标识(temporary mobile subscriber identity，TMSI)、国际移动用户标识(international mobile subscriber identity，IMSI)、或网络接入标识(network access identifier,NAI)，本申请实施例不作具体的限制。
