具体实施方式
下面结合附图和实施例对本申请的实施方式作进一步详细描述。以下实施例的详细描述和附图用于示例性地说明本申请的原理，但不能用来限制本申请的范围，即本申请不限于所描述的实施例。
在本申请的描述中，需要说明的是，除非另有说明，“多个”的含义是两个以上；术语“上”、“下”、“左”、“右”、“内”、“外”等指示的方位或位置关系仅是为了便于描述 本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
本申请中术语“和/或”，仅仅是一种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：存在A，同时存在A和B，存在B这三种情况。另外，本申请中字符“/”，一般表示前后关联对象是一种“或”的关系。
除非另有定义，本申请所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同；本申请中在申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请；本申请的说明书和权利要求书及上述附图说明中的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。本申请的说明书、权利要求书或附图中的术语“第一”、“第二”、“第三”等是用于区别不同对象，而不是用于描述特定顺序或主次关系。
在本申请中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本申请所描述的实施例可以与其它实施例相结合。
在新能源领域中，电池作为用电设备，例如电动车辆、船舶或航天器等的主要动力源，其重要性不言而喻。在本申请中，电池是指包括一个或多个电池单体(battery cell)以提供更高的电压和容量的单一的物理模块。该电池一般包括用于封装一个或多个电池单体的箱体。可选地，本申请中所提到的电池可以称之为电池包(battery pack)。可选地，该电池可以是任意类型的电池，例如：锂离子电池、锂金属电池、锂硫电池、钠离子电池、铅酸电池、镍隔电池、镍氢电池、或者锂空气电池等等。
在电池的运行、充电、换电过程中，均需要对电池的实时状态进行监控，以提高电池在上述各过程中的安全性。因此，根据实际情况的需要，在电池的内部、用电设备、换电设备等位置可配置有电池管理设备，例如：电池管理单元(BMU)等，对电池的运行状态进行监控和管理。
作为一种示例，在电动车辆以及电池的内部均配置有BMU，其中，电动车辆中的BMU可称之为主电池管理单元(Master Battery Manager Unit，MBMU)，电池的内部配置的BMU可称之为从电池管理单元(Slaver Battery Manager Unit，SBMU)。在该示例中，MBMU可以与SBMU相互连接并进行信息交互，以共同实现对电池的运行状态的监控和管理。
在一些实施方式中，MBMU与SBMU通过实体走线(例如：控制器局域网络(Controller Area Network，CAN)走线)相互连接，该实体走线在两个BMU上的安装方式较为复杂，影响制造和维修效率。在另一些实施方式中，MBMU与SBMU通过无线方式进行连接，在该无线连接方式下，MBMU与SBMU之间的通信易受到环境等多种因素的影响，因而容易出现连接故障。
可以理解的是，除了上述MBMU与SBMU以外，换电站中也会配置一种或多种BMU。该换电站中多种BMU之间，和/或，换电站中的BMU与车辆中的BMU之间也相互连接，因而，在无线连接方式下，除了上述MBMU与SBMU容易出现连接故障 以外，换电站中多种BMU之间，和/或，换电站中的BMU与车辆中的BMU之间也较为容易出现连接故障。
鉴于此，本申请提供一种电池管理设备的无线连接控制方法，其中，该电池管理设备包括但不限于是BMU，该无线连接控制方法应用于电池管理设备中的控制装置，且该控制装置连接于电池管理设备中的无线连接装置。该无线连接控制方法包括：接收连断请求命令，该连断请求命令用于指示电池管理设备与第一设备之间的无线连接或断开，根据该连断请求命令，控制无线连接装置与第一设备无线连接或断开，检测该无线连接装置的连断状态数据，根据该连断状态数据，判断电池管理设备与第一设备之间的无线连接或断开是否正常。通过该技术方案，不需要对电池管理设备的现有硬件进行改动，在电池管理设备中增加无线连接装置，且通过控制装置对该无线连接装置进行控制即可实现电池管理设备与第一设备之间的无线连接或断开，其实现方式较为简单且能够兼容现有产品。另外，电池管理设备的控制装置能够对无线连接装置的连断状态数据进行检测，并根据该连断状态数据判断电池管理设备与第一设备之间的无线连接或断开是否正常，有利于实现对电池管理设备与第一设备之间无线连断的有效监控，从而提高电池管理设备与第一设备之间的连接性能。

S1010：获取连断请求命令，该连断请求命令用于指示电池管理设备与第一设备之间的无线连接或断开。
S1021：将基于第一通信协议的连断请求命令转换为基于第二通信协议的连断请求数据。

步骤S1031和步骤S1032可以为上文图5中步骤S530的一种实现方式。
具体地，在步骤S1031中，第一预设时间段大于或等于连断请求数据在控制装置310与无线连接装置320之间的传输时间。该传输时间受控于控制装置310与无线连接装置320之间的连接方式。作为示例，在控制装置310与无线连接装置320通过SPI总线相互连接时，则数据在二者之间的传输时间大约在5ms左右。鉴于此，在本申请实施例中，第一预设时间段可以为5ms，控制装置310在向无线连接装置320发送连断请求数据之后的5ms内，检测无线连接装置320的连断状态数据。
通过该技术方案，控制装置310能够有效检测无线连接装置320最新的连断状态数据，保证数据的有效性和可靠性。根据该有效且可靠的连断状态数据，可以提升控制装置310对于无线连接装置320与第一设备之间的无线连断异常的判断的有效性及可靠性。
具体地，在步骤S1032中，控制装置310还可以每间隔第二预设时间段检测无线连接装置320当前的连断状态数据，以实现对无线连接装置320与第一设备之间无线连断的持续监控，保障该无线连接装置320与第一设备之间长期的无线连断的可靠性。
作为一种示例，本申请实施例中第二预设时间段可小于或等于100ms。在其它示例中，该第二预设时间段还可以根据实际情况进行调整，本申请实施例对该第二预设时间段的具体数值不做限定。
可选地，在一些实施方式中，上述控制装置310接收的连断请求命令可以为蓝牙连断命令，对应的，无线连接装置320可以为蓝牙芯片。
在该实施方式中，将无线连接装置320设计为蓝牙芯片，该无线连接装置320可以通过蓝牙协议与第一设备进行相互通信。该无线连接装置320可以具有蓝牙芯片的低功耗、低延时、低成本的特点，因而较为适宜的设置于车辆1和/或换电站2中，实现短距离、低成本的可靠通信。
图11示出了本申请实施例提供的一种电池管理设备300的无线连接控制方法1100的示意性流程框图。该无线连接控制方法1100可同样应用于上文图3中所示的电 池管理设备300中的控制装置310，可选地，该控制装置310可以为控制芯片，或者也可以称之为主芯片。该控制芯片(主芯片)连接于电池管理设备300中的无线通信芯片，例如：蓝牙芯片。
如图11所示，在本申请实施例中，该无线连接控制方法1100可以包括以下步骤。
S1110：接收CAN传输的蓝牙连断请求命令。
S1120：将蓝牙连断命令的报文转换为连断请求数据，该连断请求数据包括：待连接设备的蓝牙MAC，位置，连断请求。
S1130：调用连断命令处理函数，拷贝连断请求数据至SPI可访问结构体以及NVM中，并做数据校准。
S1140：调用SPI传输数据状态机，拷贝连断请求数据至SPI需传输的数组中。
S1150：调用SPI协议向蓝牙芯片传输连断请求数据。
S1160：5ms后通过SPI回读蓝牙芯片的蓝牙连断状态。
S1170：判断连断状态与连断请求数据是否相同。
S1180：从NVM中读取连断请求数据，重新调用连断命令处理函数。
具体地，上述步骤S1110至S1180的执行主体可为上文图3中所示的电池管理设备300中的控制装置310。
具体地，对于步骤S1110，在车辆的换电流程中，或者在车辆的运行过程中，电池管理设备300中的主芯片可以通过CAN总线连接于外部设备，该主芯片可以接收外部设备通过CAN总线传输的蓝牙连断请求命令，该蓝牙连断请求命令可以用于指示电池管理设备300与待连接设备(例如上文的第一设备)的蓝牙连断。
对于步骤S1120，主芯片将蓝牙连断命令的报文转换为连断请求数据，该连断请求数据包括：蓝牙MAC，待连接设备的位置，连断请求。
具体地，通过CAN总线传输的蓝牙连断命令可以为报文数据，主芯片能够将该报文数据转换为连断请求数据，该连断请求数据可以满足SPI协议。在该连断请求数据中，可以包括待连接设备的蓝牙Mac地址、位置、连断请求等信息，以便于主芯片将该连断请求数据传输至蓝牙芯片后，该蓝牙芯片能够根据该蓝牙Mac地址以及位置等信息确定待连接设备，且根据连断请求建立与待连接设备的蓝牙连断。
对于步骤S1130，主芯片可包括主程序，该主程序可以调用连断命令处理函数，该连断命令处理函数可以用于将连断请求数据同步拷贝至SPI可访问结构体以及NVM中。在拷贝过程中，可以对连断请求数据进行校准，即每拷贝一项数据，即更新该数据对应的标志位，保证连断请求数据全部进行了拷贝。
对于步骤S1140，主芯片还可包括SPI传输数据状态机，主程序可调用该SPI传输数据状态机，该SPI传输数据状态机用于将SPI可访问结构体中的连断请求数据再拷贝至SPI需传输的数组中。
对于步骤S1150，主芯片还可包括：SPI协议层，主芯片中的主程序可调用该SPI协议层，将SPI需传输的数组中的连断请求数据通过SPI传输至蓝牙芯片中。
对于步骤S1160，通过SPI协议传输一次数据时长需5ms。通过SPI协议传输数 据之后，主芯片马上回读蓝牙芯片的状态。例如，主芯片向蓝牙芯片发送连断状态请求信息，蓝牙芯片将其与待连接设备的连断状态发送回主芯片，以使得主芯片回读到蓝牙芯片与待连接设备之间当前的连断状态。
对于步骤S1170，主芯片判断连断状态与连断请求数据是否相同。若是，则表明当前蓝牙芯片与待连接设备之间正常连断，无异常发生。
若否，则执行步骤S1180，主芯片从NVM中读取连断请求数据，重新调用连断命令处理函数，再次拷贝连断请求数据至SPI可访问结构体以及NVM中。然后，重复执行上述步骤S1130至步骤S1170，以重新向蓝牙芯片传输连断请求数据，且回读蓝牙芯片的蓝牙连断状态，直至判断连断状态与连断请求数据相同，以确定当前蓝牙芯片与待连接设备之间正常连断，无异常发生。
