具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
随着新能源产业的迅速发展，电动汽车的数量逐步增加，而对充电设备的安全性、可靠性和及时性需求也不断提高。车辆控制单元(ECU)相当于汽车的大脑，ECU能够与汽车上的电子元件连接，车辆统一诊断服务(UDS)是实现车辆电子故障诊断服务制定的统一国际标准，ECU和电子元件之间需要在UDS的规定下进行通信。
充电座是安装在电动汽车上用于与充电接口连接的装置，充电座本身可能因温度过高或过低、振动、撞击等情况发生损坏，而现有的电动汽车中充电座除了具有与充电接口连接进行充电的作用，还可以对充电座的部分状态情况进行监测。
但现有技术中只能够监测充电座的状态情况，不存在对充电座进行升级的方法，但在实际工作和生活中，还要在需要的时候通过电动汽车厂商后台的服务单元对充电座进行升级，以便及时解决充电座内部在充电、监测等过程中可能产生的漏洞。因此现在亟需一种充电座升级的方法，来对充电座进行升级。
为了解决上述问题，本发明实施例提供了一种充电座升级的方法，能够对充电座进行升级。图1是本发明实施例提供的一种充电座升级的方法的步骤示意图，本说明书提供了如实施例或流程图所述的方法操作步骤，但基于常规或者无创造性的劳动可以包括 更多或者更少的操作步骤。实施例中列举的步骤顺序仅仅为众多步骤执行顺序中的一种方式，不代表唯一的执行顺序。在实际中的***或装置产品执行时，可以按照实施例或者附图所示的方法顺序执行或者并行执行。
充电座安装在电动汽车上，在向电动汽车充电时，充电桩通过充电线与充电接头连接，充电接头***充电座中对电动汽车进行充电。在充电座中设置有能够对充电座的状态信息进行监测的监测模块和与监测模块电连接的中控模块，监测模块可以包括温度监测模块、电压监测模块、插座锁监测模块和充电指示灯监测模块。
其中，中控模块与电动汽车的车辆控制单元(ECU)电连接。温度监测模块主要是对充电过程中端子、电线等的温度进行监测；电压监测模块主要是对充电过程中的充电电压进行监测；充电过程中充电接口在充电座中通过插座锁锁紧，插座锁监测模块是对插座锁是否锁紧进行监测；充电过程中充电指示灯用于指示是否正在充电，充电指示灯监测模块对充电状态进行监测。中控模块可以为单片机，中控模块中可以有存储器和处理器，存储器可以将监测模块监测到的状态信息存储，处理器可以将状态信息发送给ECU。
为了保证电动汽车能够正常使用，电动汽车厂商在需要定期对充电座进行升级，升级时可以通过厂商后台的服务单元发送升级包，升级的内容可以包括提高温度监测模块对温度进行监测的精准度，调节充电指示灯的亮度和颜色等等。其中服务单元可以为服务器。
当服务单元发送升级包时，服务单元将升级包发送给ECU，ECU通过判断是否可选择充电座升级时间进一步确定升级时间，在升级时间对充电座进行升级，在进行升级前，需要通过验证数据验证充电座是否正常，验证成功后进行升级。升级时会先将旧应用程序备份至存储器的备份区中，如果升级不成功，则将存储器备份区中的旧应用程序重新恢复。通过这种方法能够进行充电座的升级，提高升级过程的适用性，同时保证升级过程中的安全性。
参照图1，一种充电座升级的方法，应用于车辆控制单元；包括：
S001：接收升级包中的新应用程序，并检查所述升级包中的新应用程序是否有效；
S002：若有效，则将所述升级包中的新应用程序写入所述充电座存储器激活区中进行升级；
S003：判断是否升级成功，当升级成功时，将所述充电座的标志位置位，以标记升级成功。
进一步的，若所述升级包中的新应用程序有效，则可以进行升级，若进行升级，在所述升级包中的新应用程序写入所述充电座存储器激活区中之前，将所述充电座存储器激活区中的旧应用程序备份至充电座存储器备份区中，并将所述充电座存储器激活区中的旧应用程序清除，以接收所述升级包中的新应用程序。
具体的，检查所述升级包中的新应用程序是否有效可以通过ECU进行检查，检查的方法可以是通过相应的检查算法对新应用程序进行检查，确定新应用程序不存在程序缺陷等漏洞，当然也可以是其他检查的方法，本文对检查方法不做限定。为了防止充电座的应用程序升级失败后，导致整个充电座中没有可以运行的应用程序，可以将旧应用程序先在备份区备份一下，然后再将激活区中的旧应用程序清除。当升级成功时，可以将备份区中的旧应用程序清除，以达到节省存储空间的目的，然后，将标志位置位为1。在初始状态时，ECU接收到升级指令后，就会将充电座的标志位置位为0，标志位为0表示此时有升级指令，但未进行升级，需要进行充电座的升级，标志位为1表示此时升级成功，起到标记升级状态的作用，可以作为后续其他应用的依据。
在本文另一实施例中，若所述升级包中的新应用程序有效，则将所述升级包中的新应用程序写入充电座升级存储区中，车辆控制单元重启后加载新应用程序的存储地址，并将车辆控制单元重启前的旧应用程序作为备份。
其中，所述将所述升级包中的新应用程序写入所述充电座存储器激活区中进行升级，包括：
接收开始升级指令；
根据所述开始升级指令的指示，将所述升级包中的新应用程序写入所述充电座存储器激活区中进行升级；
接收升级结束指令；
根据所述升级结束指令的指示，停止将所述升级包中的新应用程序写入所述充电座存储器激活区中。
车辆控制单元ECU可以接收到服务单元发送的开始升级指令和升级结束指令，根据对应的指示进行新应用写入充电座存储器激活区的过程。
参照图2，在本发明实施例中，还包括：
S011：读取充电座的硬件信息和软件信息；
S012：根据所述硬件信息和所述软件信息，确定所述充电座是否进行升级；
S013：若进行升级，则将所述充电座存储器激活区中的旧应用程序备份至充电座存储器备份区中，并将所述充电座存储器激活区中的旧应用程序清除。
具体的，上述步骤S011至S013可以与步骤S001并行或一先一后执行，对其执行的顺序不做限定。硬件信息可以通过温度监测模块、电压监测模块、插座锁监测模块和充电指示灯监测模块进行检查，软件信息可以检查充电座内部运行的应用程序是否无差错且完整，只有硬件信息和软件信息检查通过后才可以进行升级。
参照图3，进一步的，在本发明实施例中，所述判断是否升级成功，包括：
S021：接收所述升级包中的新应用程序对应的初始校验码和终止校验码；
S022：对所述升级包中的新应用程序对应的初始校验码进行计算，确定所述升级包中新应用程序对应的标准校验码；
S023：判断所述终止校验码与所标准述校验码是否一致；
S024：若一致，则升级成功。
具体的，升级包中的新应用程序携带有初始校验码，随着新应用程序写入充电座存储器激活区，初始校验码会受程序的读入等因素影响，在新应用程序写完后，初始校验码发生改变，形成终止校验码。而ECU会接收初始校验码和终止校验码，然后依据SHA256算法对初始校验码进行计算，得到标准校验码，如果新应用程序的写入过程不存在问题、未发生异常、升级成功，则终止校验码与标准校验码应当保持一致，如果不一致，说明新应用程序写入过程存在问题，即升级不成功。
在本发明的实施例中，进行升级之前，充电座会接收车辆控制单元ECU的上电或唤醒的操作后被唤醒，唤醒后进入编程诊断会话。在检查升级包中的新应用程序有效且充电座的硬件信息和软件信息正常的情况下，将充电座存储器激活区中的旧应用程序备份至充电座存储器备份区中，并将充电座存储器激活区中的旧应用程序清除。在新应用程序写入之前，充电座会向车辆控制单元ECU发送请求写入的命令，ECU接收到命令后向服务单元发送相应请求指令，此时服务单元回传开始升级指令给ECU，ECU将升级包中的新应用程序写入充电座存储器激活区中进行升级；升级完毕后，充电座会向ECU发送请求退出的命令，ECU接收到命令后向服务单元发送相应请求指令，此时服务单元回传升级结束指令给ECU，ECU停止将升级包中的新应用程序写入充电座存储器激活区中。ECU会接收初始校验码和终止校验码，然后依据SHA256算法对初始校验码进行计算，得到标准校验码，判断标准校验码与终止校验码一致后，确认升级成功，将所述充电座的标志位置位，以标记升级成功。
参照图4，在接收升级包中的新应用程序之前，还包括：
S101：接收升级指令，根据充电座的初始状态数据和近期状态数据判断是否可选择充电座升级时间；
S102：如果可选择充电座升级时间，则从给定时间中选取升级时间；
S103：如果不可选择充电座升级时间，则将默认时间确定为升级时间；
S104：在所述升级时间通过服务单元传输的升级包对充电座进行升级。
当车辆控制单元ECU接收到服务单元发送的升级指令时，由于车辆此时可能处于正在行驶状态或者车主急需用车，此时ECU根据初始状态数据和近期状态数据判断是否可选择充电座升级时间。如果可选择充电座升级时间，则可以由车主或者直接随机在给定时间中选取升级时间，其中给定时间可以为提前预设的若干时间，比如1小时后，2小时后等等，一般来说，给定时间在12或24小时内。如果不可选择充电座升级时间，则将默认时间确定为升级时间，其中默认时间可以为提前预设的时间，比如30秒后，一般来说，默认时间为间隔较短的时间，以便及时进行升级更新。通过这种方法，可以根据车主需要和车辆的状态来进行升级时间的选择，在合适的升级时间进行充电座升级，这一过程既可以保证充电的安全，及时有效进行升级，又符合实际需求。
在本发明实施例中，步骤S101之前，ECU会获取充电座的硬件版本和软件版本，并获取服务单元发送的升级包中的版本信息，将充电座对的硬件版本和软件版本与升级包中的版本信息进行比较，如果现有版本类型与升级包中的版本类型经比较后一致，且现有版本等级低于升级包中的版本等级，则可以进行步骤S104。以保证充电座进行正确、合适的升级，提高升级的质量和效果。
参照图5，在本发明实施例中，步骤S101：所述根据充电座的初始状态数据和近期状态数据判断是否可选择充电座升级时间之前；还包括：
S201：接收服务单元用于充电座升级的验证数据，将所述验证数据发送给充电座，并接收充电座回传的加密数据；
S202：将所述加密数据发送给所述服务单元，当服务单元确定所述加密数据解密后与所述验证数据相同时；
S203：根据充电座的初始状态数据和近期状态数据判断是否可选择充电座升级时间。
具体的，通过ECU进行加密验证：ECU接收到服务单元发送的验证数据后，将验证数据发送给充电座，充电座会进行加密，得到加密数据，然后充电座会将加密数据传 送给ECU，ECU在接收后会将加密数据发送给服务单元，服务单元将加密数据解密后与验证数据进行比较，如果相同则验证通过，验证通过才可以进行后续步骤S101。这一加密验证过程中，充电座和服务单元共用一套加密***，因此充电座的加密和服务单元的解密是一个对应的过程，这一过程可以验证充电座是否为与服务单元对应的充电座，以保证充电座升级的安全性。
参照图6，在本发明实施例中，所述根据充电座的初始状态数据和近期状态数据判断是否可选择充电座升级时间，包括：
S1011：根据所述充电座的初始状态数据，确定标准状态区间；
S1012：判断充电座的近期状态数据是否在所述标准状态区间内；
S1013：如果所述近期状态数据在所述标准状态区间内，则可选择充电座升级时间。
其中，状态数据可以包括温度状态数据、电压状态数据、充电指示灯状态数据和插座锁状态数据，充电座的初始状态数据的选取时间可以为提前设定好的，电动汽车刚出厂时对应的时间段，初始状态数据为上述状态数据在电动汽车刚出厂时的状态。由于电动汽车刚出厂时各种性能处于最优状态，因此以这个时间段对应的状态数据选作初始状态数据，可以作为后期各种状态性能的基准，由此可以确定标准状态区间。
然后进一步判断充电座近期状态数据是否在标准状态区间内，近期状态数据可以为接收到升级指令前一周、前三天等对应的状态数据，因为这种最近时间段的近期状态数据才能够反应出充电座的最近状态。最后如果近期状态数据在标准状态区间内，则可以选择充电座升级时间，即充电座的近期状态与刚出厂时状态相近，表明充电座的状态仍旧不错，以此作为是否可选择充电座升级时间的标准。
参照图7，在本发明实施例中，步骤S1011中所述根据所述充电座的初始状态数据，确定标准状态区间，包括：
S1011a：将所述充电座的所述初始状态数据中的异常数据剔除；
S1011b：确定所述初始状态数据的标准值和误差值；
S1011c：根据所述标准值和误差值确定所述标准状态区间。
具体的，电动汽车刚出厂时，无法避免充电座因为人为因素或自然因素导致获取到的初始状态数据中有些许异常数据，这些异常数据可能表现为温度突增或突降，充电指示灯短暂熄灭等等。但是由于这些许异常数据并不是因为充电座自身出现问题而产生 的，因此这些异常数据不具备代表性，需要将其剔除，可以使用孤立森林模型对异常数据进行剔除。
在将异常数据剔除后，可以确定初始状态数据的标准值和误差值，具体的，由于初始状态数据服从正态分布，将初始状态数据符合正态分布曲线，通过正态分布曲线可以确定初始状态数据的期望值μ和方差σ，进而可以根据实际需求将期望值确定为初始状态数据的标准值，将一倍方差、二倍方差或三倍方差确定为初始状态数据的误差值。其中一倍方差、二倍方差或三倍方差作为初始状态数据的误差值时，会导致确定的标准状态区间的大小不同，原则上，一倍方差作为误差值所确定的标准状态区间小于二倍方差作为误差值所确定的标准状态区间，二倍方差作为误差值所确定的标准状态区间小于三倍方差作为误差值所确定的标准状态区间。
标准状态区间的范围越大，近期状态数据在标准状态区间内的概率就越高，因此标准状态区间的范围可以根据实际需求来进行选择，如果对精准度要求更高，包容性要求较低，就可以选择一倍方差作为误差值，如果对精准度要求不高，对包容性要求更高，就可以选择三倍方差作为误差值。以此来满足不同的精准度和包容性要求。
需要注意的是，对于温度、电压等状态数据存在不同时间点温度或电压高低不同，服从正态分布，可以用上述方式确定标准状态区间。但是对于充电指示灯、插座锁等状态数据，在不同时间点只可能存在亮或灭，锁紧或未锁紧这两种状态，无法用上述方式确定标准状态区间。对于这类状态信息，以充电指示灯的状态信息为例，异常数据可以为0，0表示充电指示灯不亮或闪烁，标准值为1，1表示充电指示灯亮起，误差值设定为0，即不允许存在误差，通过标准值和误差值确定标准状态区间。
进一步的，所述根据所述标准值和误差值确定所述标准状态区间，包括：
将所述标准值与所述误差值之差确定为所述标准状态区间的左端点值，将所述标准值与所述误差值之和确定为所述标准状态区间的右端点值。
具体的，所述标准状态区间通过如下公式确定：
M∈[A-B，A+B]；
其中，M为标准状态区间，A为标准值，B为误差值。
具体的，如果将σ(一倍方差)作为初始状态数据的误差值，则标准状态区间可以确定为[μ-σ，μ+σ]；如果将2σ(二倍方差)作为初始状态数据的误差值，则标准状态区间可以确定为[μ-2σ，μ+2σ]；如果将3σ(三倍方差)作为初始状态数据的误差值，则标准状态区间可以确定为[μ-3σ，μ+3σ]。
需要注意的是，对于温度、电压等状态数据可以通过上述方法确定标准状态区间，对于充电指示灯、插座锁等状态数据可以确定标准状态区间为[1，1]，其中1代表充电指示灯亮起，或插座锁锁紧。
参照图8，此外，在本发明实施例中，所述根据充电座的初始状态数据和近期状态数据判断是否可选择充电座升级时间，包括：
S1014：比较所述近期状态数据与所述初始状态数据，判断所述近期状态数据与所述初始状态数据是否一致；
S1015：如果所述近期状态数据与所述初始状态数据一致，则可选择充电座升级时间。
其中，在电动汽车出厂后的一段时间内，选取其中任意时间点充电座对应的状态数据作为初始状态数据，在选取该时间点时，需要确保该时间点充电座的状态良好，没有异常情况发生，这时的状态数据才具备代表性。
进一步的，判断近期状态数据与初始状态数据是否一致，对于温度状态数据和电压状态数据来说，此处的一致可能并非完全相同，在允许的误差范围内，都算作一致，例如，可以将温度误差范围设置在±0.1℃，初始状态数据中的温度为10摄氏度，则在9.9-10.1℃内均确定为一致。但是对于充电指示灯状态数据和插座锁状态数据来说，此处的一致可能为完全相同，不存在允许的误差范围，只有充电指示灯状态数据与初始充电指示灯状态数据一致，均为1(充电指示灯亮起)，或插座锁状态数据与初始插座锁状态数据一致，均为1(插座锁锁紧)才能确定为两者一致。
进一步的，还包括：当升级失败时，将所述充电座存储器备份区中的旧应用程序重新恢复至所述充电座存储器激活区中。
如果升级失败，标志位为0，将备份区中的旧应用重新恢复至激活区中，此时标志位仍旧为0，标志位为0，表示此时有升级指令，但未进行升级(升级未成功)，需要进行充电座的升级。
通过上述一系列步骤，可以通过充电座的近期状态数据与初始状态数据进行比较，判断充电座是否可选择充电座的升级时间，如果近期状态数据在由初始状态数据确定的标准状态区间内，或者近期状态数据与初始状态数据一致，则可以选择充电座的升级时间，以提高***的交互性和可用性。如若不然，则需要将默认时间确定为升级时间，以提高***的安全性，保证充电座能够高性能高质量的完成充电任务。在升级时间到来时，可以先进行备份，再进行升级，目的是防止充电座升级不成功的情况发生，即使升 级不成功，可以续用之间的旧应用程序，避免因升级不成功造成无限等待后续维修升级的过程，提高了充电座的升级效率。
参照图9，基于上述所述的一种充电座升级的方法，需要设计一种充电座使得充电座升级的方法基于充电座来进行升级，其中充电座1包括中控模块2，以及与中控模块2电连接的监测模块3；
所述监测模块3用于采集所述充电座1的状态信息并将所述状态信息传递给所述中控模块2；
所述中控模块2与车辆控制单元4电连接，所述中控模块2用于将所述状态信息传递给所述车辆控制单元4，并在车辆控制单元4的控制下在升级时间进行升级。
具体的，监测模块3可以包括温度监测模块、电压监测模块、插座锁监测模块和充电指示灯监测模块。温度监测模块主要是对充电过程中端子、电线等的温度进行监测；电压监测模块主要是对充电过程中的充电电压进行监测；充电过程中充电接口在充电座中通过插座锁锁紧，插座锁监测模块是对插座锁是否锁紧进行监测；充电过程中充电指示灯用于指示是否正在充电，充电指示灯监测模块对充电状态进行监测。
