随着新能源汽车在市场占有率的逐渐升高，新能源汽车电池是影响汽车运行的重要部件，当前汽车动力域出现问题首先需要对汽车电池进行故障检测，所以电池的故障检测频率较高。
传统的汽车电池的故障诊断需要使用专用的故障诊断设备，通过在汽车的OBD诊断接口插入CAN线读取故障信息，操作较为繁琐。
有鉴于此，本申请实施例提供了一种故障诊断的方法和故障诊断设备，故障诊断设备通过与车辆之间的无线连接来获取车辆上的电池的故障信息，不再使用CAN线的通讯方式，可以提高诊断人员操作的便利性，节约故障诊断时间，提高效率。
图1示出了本申请实施例的故障诊断的方法的应用场景的一种示意图。该方法涉及到故障诊断设备11和车辆10之间的无线交互。具体地，涉及到故障诊断设备11和车辆10上的电池管理单元12之间的无线交互。电池管理单元12用于管理车辆10上的电池13。例如，用于控制电池13中的继电器的断开和闭合。再例如，用于采集电池13的电压、温度、电流等。故障诊断设备11用于对车辆10，进行故障诊断，以便于诊断人员对车辆10进行维修。更具体地，故障诊断设备11用于对车辆10上的电池13进行故障诊断。
可选地，在本申请实施例中，故障诊断设备11和车辆10之间的无线通信，可以包括但不限于蓝牙通信、WiFi通信、ZigBee通信等各种方式，在此并不限定。
可选地，车辆10上可以安装多个电池13，车辆10上可以设置第一电池管理单元，该第一电池管理单元可用于管理车辆10上安装的多个电池，例如，可称第一电池管理单元为主电池管理单元(Master Battery Management Unit，MBMU)。每个电池10可对应设置一个第二电池管理单元，例如，可称该第二电池管理单元为从电池管理单元(Slave Battery Management Unit，SBMU)。MBMU可以从SBMU获取电池的电流值、电芯电压、继电器状态以及功率等状态。其中，MBMU与SBMU之间的通讯方式不限于无线蓝牙、CAN总线、以太网、5G网络通讯等方式。
在一些实施例中，SBMU可利用对应电池的电池管理系统(Battery Management System，BMS)来实现；MBMU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。
需要说明的是，由于车辆10和故障诊断设备11之间通过无线连接进行通信，因此，如图1所示，故障诊断设备11可以同时与多个车辆10进行无线通信。也就是是，故障诊断设备11可以同时对多个车辆10进行故障诊断。
图2示出了本申请实施例的故障诊断的方法200的示意性框图。应理解，该方法200可以由图1所示的故障诊断设备11执行。第一用电装置可以是如图1所示的车辆10。具体地，如图2所示，该方法200包括以下部分或全部内容。
S210，在故障诊断设备与第一用电装置建立无线连接之后，故障诊断设备向第一用电装置发送第一指令，第一指令用于请求读取第一用电装置上的第一电池的故障信息。
S220，故障诊断设备接收第一用电装置基于第一指令发送的第一电池的故障信息。
S230，故障诊断设备解析第一电池的故障信息，并控制故障诊断设备的输出装置向诊断人员输出第一电池当前存在的故障。
当第一用电装置到达厂家指定的维修地点时，维修地点内的故障诊断设备可以与第一用电装置建立无线连接。例如蓝牙连接、WiFi连接、ZigBee连接等。具体地，故障诊断设备可以与用电装置上的电池管理单元(例如，MBMU或SBMU)建立无线连接。也就是说，故障诊断设备设置有无线通信模块，而用电装置上的电池管理单元也设置有无线通信模块。故障诊断设备和用电装置上的电池管理单元通过各自的无线通信模块建立无线连接。需要说明的是，在本申请实施例中，在故障诊断设备与第一用电装置建立无线连接之后，故障诊断设备与第一用电装置之间的交互可以均通过无线连接实现。
在故障诊断设备与第一用电装置建立无线连接之后，故障诊断设备可以向第一用电装置发送第一指令，即读取第一电池的故障信息的指令。在第一用电装置接收到该第一指令之后，第一用电装置可以向故障诊断设备发送该第一用电装置上的第一电池的故障信息。即故障诊断设备可以接收第一用电装置基于该第一指令发送的该第一用电装置上的第一电池的故障信息。进一步地，故障诊断设备可以对该第一电池的故障信息进行解析，并控制故障诊断设备的输出装置，例如，显示屏，向诊断人员输出第一电池当前存在的故障。
在一种实施例中，在故障诊断设备与第一用电装置建立无线连接之后，故障诊断设备可以自主向第一用电装置发送第一命令。在另一种实施例中，在故障诊断设备与第一用电装置建立无线连接之后，诊断人员也可以对故障诊断设备进行输入操作。例如，故障诊断设备具有显示屏，显示屏上显示有引导诊断人员点击的图标，该图标可以指示第一指令，诊断人员通过在该图标上的点击操作，触发故障诊断设备向第一用电装置发送该第一指令。
需要说明的是，第一电池是指第一用电装置上的电池，可以是指一个电池，也可以是指多个电池。当第一用电装置上安装有多个电池时，第一用电装置可以向故障诊断设备发送存在故障的所有电池的故障信息。

可选地，在其他实施例中，在故障诊断设备与第一用电装置建立无线连接之后，第一用电装置也可以向故障诊断设备发送第一电池的参数，例如，第一电池的电量、电压和温度等。故障诊断设备可以根据接收到的该第一电池的参数信息，确定第一电池当前存在的故障。进而故障诊断设备可以控制故障诊断设备的输出装置向诊断人员输出第一电池当前存在的故障。
可选地，在本申请实施例中，方法还包括：故障诊断设备向第一用电装置发送第二指令，第二指令用于指示清除第一电池当前存在的故障。
电池存在的故障，通常分为两大类，一种是可以通过软件清除的，一种是需要对电池进行维修的。也就是说，故障诊断设备可以在对第一电池的故障信息解析之后，可以确定第一电池当前存在的故障属于哪一类。若属于第一类，则故障诊断设备可以向第一用电装置发送第二指令，即清除第一电池当前存在的故障的指令。
在该实施例中，故障诊断设备向第一用电装置发送第二指令，从而可以快速清除第一电池当前存在的故障。
同样地，在一种实施例中，故障诊断设备一旦接收到第一电池的故障信息之后，可以自主向第一用电装置发送第二指令，第一用电装置在确定第一电池当前存在的故障为第一类故障，则可以清除第一电池当前存在的故障，例如，可以清除存储在第一用电装置内部的故障码。
而在另一种实施例中，故障诊断设备向第一用电装置发送第二指令，包括：根据诊断人员的输入操作，故障诊断设备向第一用电装置发送第二指令。
具体地，可以在故障诊断设备的显示屏显示引导诊断人员点击的图标，该图标可以指示第二指令，即清除第一电池当前存在故障的指令。诊断人员通过在该图标上的点击操作，触发故障诊断设备向第一用电装置发送该第二指令。第一用电装置在接收到该第二指令之后，就可以清除该第一电池存在的故障。
在该实施例中，故障诊断设备可以基于诊断人员的输入操作，向第一用电装置发送第二指令，从而可以避免在第一电池所存在的故障为非软件清除时发送的无效指令。
对于第二类电池故障，则需要诊断人员对第一电池当前存在的故障进行主观分析、查阅资料以及联系厂家技术人员来对第一电池进行维修。
可选地，在诊断人员确定第一电池当前存在的故障为第二类电池故障，故障诊断设备可以根据诊断人员的操作在云平台中查询与该第一用电装置的第一电池的故障相匹配的故障案例，进而查询该故障案例对应的案例信息，并通过故障诊断设备的输出装置向诊断人员展示，以使得诊断人员对所述第一电池进行维修。
需要说明的是，诊断人员，可以是驻维修站的工作人员或技术员，也可以是驾驶员自身。
可选地，在本申请实施例中，方法200还包括：在故障诊断设备断开与第一用电装置之间的无线连接之前，且在故障诊断设备与第二用电装置建立无线连接之后，
故障诊断设备向第二用电装置发送第三指令，第三指令用于请求读取第二用电装置上的第二电池的故障信息。
第二用电装置是指与第一用电装置不同的用电装置，第二电池是指第二用电装置上的电池，第二用电装置与第一用电装置可以是同一类型的用电装置，也可以是不同类型的用电装置，例如，第二用电装置与第一用电装置均为车辆。应理解，本申请实施例的第二用电装置与故障诊断设备之间的交互可以参考第一用电装置与故障诊断设备之间的交互，为了简洁，此处不作过多描述。
在该实施例中，由于用电装置与故障诊断设备之间通过无线连接通信，因此，故障诊断设备可以同时对多个用电装置进行故障诊断，并将诊断结果汇总。例如，出租车公司，可以同时对停放的多辆出租车电池进行故障检测，短时间内分析多辆车的电池状态，可以很大程度地节省故障检测时间。
可选地，在本申请实施例中，方法还包括：故障诊断设备获取第一用电装置的MAC地址信息；故障诊断设备根据MAC地址信息，向第一用电装置发起蓝牙连接请求。
需要说明的是，在故障诊断设备与第一用电装置建立起蓝牙连接之后，故障诊断设备和第一用电装置之间的交互均可以通过蓝牙连接实现。

在该实施例中，故障诊断设备可以在云端服务器查找到用电装置的MAC地址信息，进而可以基于该MAC地址信息，向用电装置发起蓝牙连接请求，而后可以通过蓝牙连接与用电装置进行信息交互，可以确保数据传输的稳定性，并且可以降低维修成本。
在其他实施例中，故障诊断设备可以通过其他系统获取第一用电装置的MAC地址信息。例如，故障诊断设备可以通过射频识别系统获取用电装置的MAC地址信息，本申请实施例对此不作限定。
可选地，在本申请实施例中，方法200还包括：故障诊断设备在接收到第一电池的故障信息之后或者接收到第一用电装置发送的故障清除完成指令之后，断开与第一用电装置之间的无线连接。
正如上文描述的，电池故障可以分为两类，若第一电池当前存在的故障属于需要对电池进行维修的故障，那么在故障诊断设备向诊断人员展示第一电池当前存在的 故障之后或者在接收到第一用电装置发送的故障清除完成指令之后，可以在故障诊断设备的显示屏显示引导诊断人员点击的图标，该图标指示断开与第一用电装置之间的无线连接。
可选地，在本申请实施例中，该输出装置可以是显示屏。该输出装置也可以是扬声器。
