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。此外，术语“第一”、“第二”、 “第三”等仅用于描述目的，而不能理解为指示或暗示相对重要性。“垂直”并不是严格意义上的垂直，而是在误差允许范围之内。“平行”并不是严格意义上的平行，而是在误差允许范围之内。
下述描述中出现的方位词均为图中示出的方向，并不是对本申请的具体结构进行限定。在本申请的描述中，还需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可视具体情况理解上述术语在本申请中的具体含义。
在本申请实施例中，电池可以为锂离子电池、锂金属电池、铅酸电池、镍隔电池、镍氢电池、锂硫电池、锂空气电池或者钠离子电池等，在此并不限定。从规模而言，电池可为电池单体、电池模组或电池包，在此并不限定。
随着新能源技术的发展，电池的应用领域越来越广泛，如可以为用电装置提供动力或者为用电装置供电。例如，电池可以作为动力源为车辆提供动力，在车辆中电池的电量不足以支持车辆继续行驶的情况下，可利用充电桩等充电设备对车辆进行充电，即对车辆中的电池进行充电，以实现电池的充、放电循环使用。但电池充电需要花费较长时间，限制了车辆的续航使用。
为了提高车辆的续航使用率，换电技术应运而生。换电技术采用“车电分离”的方式，可以通过换电站为车辆提供电池更换服务，即电池可以从车辆上快速取下或者安装。从车辆上取下的电池可以放入换电站的换电柜中进行充电，以备为后续进入换电站的车辆进行换电。
目前在换电场景中，各电池管理设备之间的交互采用的是控制器局域网(Controller Area Network，CAN)，这是一种有线通信方式，需要有物理线束及接插件用于数据传输。由于车辆换电频次高，每次换电都需要经过车辆接插件的拔插，并且接插件是损耗件，多次换电后可能会出现接插件或线束损坏导致通讯异常，从而影响了通信可靠性。
有鉴于此，本申请实施例提供了一种电池管理设备，在该电池管理设备内部集成蓝牙芯片，主控芯片通过蓝牙芯片与其他设备的蓝牙芯片之间的无线通信实现与其他设备的数据交互，也就是说，电池管理设备与其他设备之间采用蓝牙通信的方式，不会产生因接插件或线束损坏带来的通讯问题，从而提高了通信可靠性。
需要说明的是，本申请实施例中的电池管理设备可以是本领域技术人员所理解的电池管理单元(Battery Management Unit，BMU)，也可以是能够实现无线通信的普通控制器。例如，在将电池单体到底盘(cell to chassis，CTC)场景中，也就是，将电池放在底盘之中，电池管理设备可以是用电装置上的控制器，其既可以实现电池内的电池管理单元的功能，又可以实现用电装置上的电池管理单元的功能，还可以实现现有的整车控制器(Vehicle control unit，VCU)的功能，本领域技术人员对此不作限定。
图1示出了本申请实施例适应的一种电池系统的高压架构拓扑图。如图1所示，该电池系统包括多个并联在一起的电池(10_1，……，10_N)。每个电池内部还可以一个负极继电器(102_1，……，102_N)，该负极继电器与电池内由多个电池单体组成的电池模组的负极串联，该负极继电器用于控制电池(10_1，……，10_N)与用电装置的高压系统连接与断开。每个电池内部可以设置一个从电池管理单元(Slave Battery Management Unit，SBMU)(101_1，…..，101_N)，用于获取对应电池的电流值、电芯电压、继电器状态以及功率等状态。电池系统还可以包括主正继电器30，该主正继电器设置在多个电池(10_1，……，10_N)并联之后的母线上，用于控制用电装置的高压系统与外部的充电装置或用电装置的连接与断开。该电池系统还可以包括预充继电器40和预充电阻50，用于进行上高压预充。该电池系统内还设置有主电池管理单元(Master Battery Management Unit，MBMU)20，MBMU 20与SBMU(101_1，…..，101_N)相互通讯，MBMU 20可以从SBMU(101_1，…..，101_N)获取电池(10_1，……，10_N)的电流值、电芯电压、继电器状态以及功率等状态。以实现对电池(10_1，……，10_N)的控制管理。
在一些实施例中，SBMU(101_1，…..，101_N)可利用对应电池(10_1，……，10_N)的电池管理系统(Battery Management System，BMS)来实现；MBMU 250可以通过电池断路单元(Battery Disconnect Unit，BDU)的控制模块来实现，也可以通过其中一个电池的BMS来实现。
图2示出了本申请实施例的电池管理设备200的示意性框图。该电池管理设备200可以是图1所示的MBMU，也可以是图1所示的SBMU。可选地，该电池管理设备200还可以是换电站内的电池管理单元，例如，换电站内集成在管理装置的传输电池管理单元(Transmission Battery Management Unit，TBMU)或者是换电站内集成在换电柜的充电电池管理单元(Charger Battery Management Unit，CBMU)。如图2所示，该电池管理设备包括以下或全部内容。

处理器，能够快速唤醒MCU、超低待机电流、灵活的射频核心以及更多的外设等优点。该主控芯片220也可以采用任一种型号的微控制单元(Microcontroller Unit，MCU)，例如，该主控芯片可以采用型号为TC275的微控制器。
在该实施例中，在该电池管理设备200内部集成蓝牙芯片210，主控芯片220通过蓝牙芯片210与其他设备的蓝牙芯片之间的无线通信实现与其他设备的数据交互，也就是说，电池管理设备200与其他设备之间采用蓝牙通信的方式，不会产生因接插件或线束损坏带来的通讯问题，从而提高了通信可靠性。
可选地，如图3所示，所述蓝牙芯片210还用于生成唤醒信号，所述唤醒信号用于唤醒所述主控芯片220。
具体地，蓝牙芯片210可以连接到主控芯片220上的一个通用输入输出(General Purpose Input/Output，GPIO)接口，当主控芯片220处于休眠状态时，蓝牙芯片210与主控芯片的相连的管脚会相应发出一个电平信号，该电平信号会传递到主控芯片220上，从而可以将主控芯片220唤醒，进入到工作模式。
需要说明的是，在电池管理设备200内部可能还会集成其他唤醒源，例如，该电池管理设备200内部可以集成wifi芯片，wifi芯片也可以生成唤醒信号，该唤醒信号用于唤醒主控芯片220。也就是说，主控芯片220既可以通过蓝牙芯片210产生的唤醒信号唤醒，也可以通过其他唤醒源产生的唤醒信号唤醒。只要有一个唤醒源产生唤醒信号，该主控芯片220就唤醒，进入到工作模式。
在该实施例中，通过蓝牙芯片210唤醒主控芯片220，可以不用额外设置其他唤醒源，从而可以简化电池管理设备的结构。
可选地，在本申请实施例中，所述蓝牙芯片210还用于获取所述主控芯片的更新程序，所述更新程序用于对所述主控芯片内部的程序进行更新。
通常主控芯片210内部的程序需要周期性地刷新，以完善电池管理设备200的功能。该更新程序可以从云端获取，例如，该电池管理设备200内部可以设置wifi芯片，主控芯片220可以通过wifi芯片从云端获取到该主控芯片220的更新程序。在本申请实施例中，该主控芯片220可以通过蓝牙芯片210从其他设备处获取该主控芯片220的更新程序。具体地，蓝牙芯片210可以接收其他设备的蓝牙芯片发送的主控芯片220的更新程序。
在该实施例中，通过蓝牙芯片210获取的主控芯片210的更新程序，以对主控芯片210内部的程序更新，可以完善电池管理设备200的功能。例如，设置在电池内部的电池管理设备200可以通过对程序更新，清除电池当前所存在的部分故障。
可选地，如图4所示，该电池管理设备200还包括：存储芯片230，用于存储蓝牙芯片210获取的更新程序；该蓝牙芯片210还用于向主控芯 片220发送触发信号，该触发信号用于触发主控芯片220从存储芯片230处获取该更新程序，以对主控芯片220内部的程序进行更新。
可选地，该存储芯片230可以是FLASH存储器。其存储容量大，可以与MCU之间通过命令的方式进行读写、擦除操作。当蓝牙芯片210接收到其他设备的蓝牙芯片发送的主控芯片220的更新程序之后，该蓝牙芯片210可以与存储芯片230之间进行交互，以将该更新程序存储在存储芯片230中。存储芯片230可以进一步地向主控芯片230发送触发信号，使得主控芯片230读取该存储芯片230内存储的更新程序，并进行更新。
在该实施例中，通过专用的存储芯片230存储主控芯片220的更新程序，可以避免在主控芯片220未获取该更新程序的情况下，该更新程序的丢失。
可选地，如图5所示，该蓝牙芯片210用于从换电站内的管理装置300处获取该更新程序。
可选地，该电池管理设备200设置于用电装置内或者电池内。也可就是说，该电池管理设备200可以是主电池管理设备MBMU或者是从电池管理设备SBMU。若该电池管理设备200是MBMU，蓝牙芯片210可以直接从管理装置300处接收主控芯片220的更新程序，蓝牙芯片210也可以从管理装置300处接收SBMU的主控芯片的更新程序，并转发给SBMU的蓝牙芯片。若该电池管理设备200是SBMU，则蓝牙芯片210通过MBMU的蓝牙芯片间接从管理装置300处接收主控芯片220的更新程序。当用电装置到达换电站时，若换电站内的管理装置300获取到主控芯片210的更新程序，管理装置300可以通过其内部的蓝牙芯片向电池管理设备200内的蓝牙芯片210发送该更新程序。可选地，管理装置300可以从云端获取该主控芯片210的更新程序。
在该实施例中，电池管理设备200的主控芯片220的更新程序是从换电站的管理装置处获取的，无需在电池管理设备200内设置与云端通信的通信芯片，只需要电池管理设备200的蓝牙芯片210与管理装置300之间进行通信交互即可获得，故可以降低该电池管理设备200自身的成本以及在通信过程中的成本。
可选地，在本申请实施例中，该电池管理设备200设置于用电装置内，主控芯片220用于通过该蓝牙芯片210与换电站内的管理装置300交互换电数据，该换电数据用于控制用电装置在换电站内更换电池。
例如，电池管理设备200为MBMU，MBMU可以与管理装置300内的TBMU交互。具体地，该TBMU内部也集成蓝牙芯片，蓝牙芯片210与TBMU内的蓝牙芯片进行无线通信，使得MBMU内的主控芯片220与TBMU内的主控芯片可以交互换电数据。
在该实施例中，用电装置内的电池管理设备200通过蓝牙芯片210与管理装置300交互换电数据，有利于管理装置300在换电之前确定用电装置上的电池是否存在影响换电的故障，从而可以避免将电池从用电装置上拆下来再退回去的情况发生，有利于提高换电效率。
