随着新能源技术的快速发展，为新能源服务的各项技术也得到了极大的提高。基于充电困难、充电速率慢、电池续航能力有限等方面考虑，针对新能源汽车的换电技术应运而生。
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。
然而，现阶段，换电站内的动力电池整个充电过程的持续时间较长，影响用户使用体验。示例性地，在换电站以及换电站内的可用电池的数量不足以满足用户需求的具体应用场景下，动力电池的充电时间过长将会导致换电站的换电效率低下，从而影响用户的使用体验。
因此需要一种能够提高动力电池充电效率的技术方案。
基于此，本申请实施例提供了动力电池的充电方法、装置、设备和介质，可以应用到车辆换电的应用场景中。通过本申请实施例提供的动力电池的充电方案，能够提高动力电池的充电效率，提高用户使用体验。
为了更好的理解本申请，在开始介绍本申请实施例提供的车辆控制方案之前，本申请实施例先依次对本申请涉及的车辆、动力电池、换电站等概念作具体解释说明。
(1)车辆，本申请实施例的车辆可以与电池可拆卸连接。在一些实施例中，车辆可以是小汽车、货车等以动力电池为动力源的车辆。
(2)动力电池，本申请实施例中的动力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，在此不作限定。
从规模而言，动力电池也可以为电池单体，也可以是电池模组或电池包，在此不作限定。
从应用而言，动力电池可以应用于电动汽车内，为电动汽车的电机供电，作为电动汽车的动力源。电池还可为电动汽车中的其他用电器件供电，比如为车内空调、车载播放器等供电。
(3)换电站，在本申请实施例中，换电站可以指为车辆提供换电服务的场所。比如，可以是固定的场所，或者是诸如移动换车车辆等移动场所，本申请实施例对此不作限定。
在介绍完上述概念之后，为了便于理解，在对本申请实施例提供的动力电池的充电方案进行具体说明之前，本申请实施例的下述部分将先对一种示例性地换电场景展开具体说明。
图1是本申请实施例提供的一种示例性的换电场景的场景示意图。如图1所示，换电站12可以包括换电柜121。其中，换电柜121可以包括多个充电仓122。
当安装有动力电池P1的车辆11驶入换电站12之后，换电站12通过换电装置将动力电池P1从车辆11取下，并从充电仓122中取出动力电池P2，然后将动力电池P2安装到车辆11上之后，安装有动力电池P2的车辆11可以驶离换电站12。通过该换电技术，可以在几分钟、甚至数十秒内对车辆进行快速的能量补充，提高了用户的体验。
另外，对于取下的动力电池P1，可以将其放入空闲的充电仓122内进行充电，以便于换电站12继续为其他车辆提供换电服务。在介绍完换电场景之后，接下来，为了便于理解，在对本申请实施例提供的动力电池的充电方案进行具体说明之前，本申请实施例的下述部分将先对换电系统展开具体说明。

首先，对于该无线通信链路。在一些实施例中，该无线通信链路可以是第二BMU基于第一BMU的物理地址请求建立的。其中，第一BMU的物理地址可以是第一BMU的媒体访问控制(Media Access Control，MAC)地址。其中，不同动力电池的第一BMU的物理地址不同。在一些实施例中，该无线通信链路可以是蓝牙连接的通信链路。 需要说明的是，该无线通信链路还可以是无线保真(Wireless Fidelity，Wi-Fi)等无线通信链路，对此不作具体限定。
其次，对于第一BMU的物理地址的获取方式。
在第一个示例中，换电站的换电装置取下动力电池之后，可以通过信息读取装置从设置于第一BMU内部或者外壳上的信息存储装置内直接读取该物理地址。在一个具体的示例中，对于信息存储装置和信息读取装置的具体类型，信息存储装置可以是具备能够存储信息功能以及能被信息读取装置读取信息功能的设备。比如，信息存储装置可以是射频识别(Radio Frequency Identification，RFID)标签，相应地，信息读取装置可以是RFID阅读器。需要说明的是，信息存储装置和信息读取装置还可以是其他具备信息读取以及被读取功能的配套设备，比如芯片等，对此不作具体限定。在一个具体的示例中，对于信息读取装置的使用方式。信息读取装置可以设置于电池运输装置上，从而信息读取装置可以在动力电池运输至换电仓的过程中读取该物理地址。示例性地，信息读取装置可以设置于堆垛机上。当换电装置将取下的动力电池放置于堆垛机之后，信息读取装置可以读取动力电池的物理地址。又或者，可以是车辆在抵达指定区域之后，通过信息读取装置获取该物理地址。比如，可以在换电站的入口处设置信息读取装置，或者在车辆抵达指定换电区域之后，通过信息读取装置读取该物理地址。
需要说明的是，当在入口处或者指定换电区域读取到该物理地址时，可以先于或者同步于更换电池的流程执行本申请实施例提供的充电方法，进一步提高了充电效率。
在第二个示例中，为了提高信息的安全性，换电站的服务器可以通过该信息读取装置从该信息存储装置内获取第一BMU的标识信息或者动力电池的标识信息之后，换电站的服务器通过预设的标识信息与物理地址的对应关系中查询得到与所获取的标识信息对应的物理地址，然后将该物理地址发动至第二BMU的。其中，信息读取装置的具体内容可以参见本申请上述实施例的相关说明，在此不再赘述。在一个具体地示例中，动力电池的标识信息可以包括电池包序号(Packet Number，PN)码。
通过本示例，防止了信息读取装置内的信息被恶意读取之后会造成车辆或者电池的信息泄露，从而提高了车辆以及电池包的信息安全性。
在第三个示例中，为了提高信息的安全性，换电站的服务器通过该信息读取装置从该信息存储装置内获取车辆标识信息、第一BMU的标识信息或者动力电池的标识信息等标识信息之后，将其读取得到的标识信息发送至云端服务器，由云端服务器通过预设的标识信息与物理地址的对应关系中查询得到与所获取的标识信息对应的物理地址，并将该物理地址信息通过换电站的服务器发送至第二BMU。
通过本示例，防止了信息读取装置内的信息被恶意读取之后会造成车辆或者电池的信息泄露，从而提高了车辆以及电池包的信息安全性。
在一个具体的示例中，为了进一步提高信息安全性，在将换电站的服务器的标识信息发送至云端服务器之后，云端服务器可以根据动力电池或者第一BMU的标识信息对动力电池进行身份验证，在身份验证通过之后，将第一BMU的物理地址返回云端 服务器。
通过本示例，当大量的电池在换电站之间不断流转时，当云端服务器对第一BMU身份验证通过之后，才会将第一BMU的物理地址发送至第二BMU，以使第二BMU基于该物理地址与第一BMU建立无线通信连接。从而可以防止使用劣质电池来换取换电站的优质电池等行为造成的损失以及安全隐患。
在第四个示例中，换电站的服务器可以在车辆抵达指定区域之后，通过图像采集装置获取车辆的车牌信息，然后在云端服务器或者换电站的服务器中基于预设的车牌信息与第一BMU的物理地址的绑定关系，确定第一BMU的物理地址。其中，图像采集装置可以是摄像装置、监控器、照相机等具有图像采集功能的设备或者模块。
在一个具体地示例中，在完成对车辆的换电之后，可以该绑定关系中该车辆与更换前的动力电池的第一BMU的物理地址的对应关系替换为将该车辆与更换后的动力电池的第一BMU的物理地址的对应关系。
通过本实施例，当用户绕过换电站私自更换电池时，比如用户将车辆的电池A私自更换为电池B之后，当用户再需要在换电站中继续更换电池时，通过上述绑定关系，会返回电池A的第一BMU的物理地址。第二BMU在获取该物理地址之后，将无法与车辆内的电池B的第一BMU建立无线通信连接，从而保证了电池的可靠性。
在第五个示例中，车辆本体内的第三BMU可以获知车辆所安装动力电池的第一BMU的物理地址。在车辆抵达换电站之后，第三BMU与换电站的服务器之间建立无线通信链路，然后第三BMU通过该无线通信链路将第一BMU的物理地址发送至换电站的服务器。
通过本示例，在第三BMU与换电站的服务器建立无线通信链路之后，即可开始执行本申请实施例提供的充电方法，从而使得在电池入仓之前即可开始对电池进行软件更新。相较于车辆进入换电仓之后，开始软件更新的方案相比，提高了充电效率。在一个具体地换电场景中，在动力电池拆卸以及运输过程中即可完成动力电池的第一BMU的软件更新，也就是说，在电池进入充电仓前即可完成软件更新，提高了充电效率。
在第六个示例中，车辆可以向云端服务器发送换电请求，该换电请求包括车辆的标识信息、动力电池的标识信息或者动力电池的第一BMU的物理地址信息等。在该换点请求包括车辆的标识信息、或者动力电池的标识信息的情况下，云端服务器可以基于该标识信息查询动力电池的第一BMU的物理地址，然后将该物理地址发送至换电站的服务器。或者，在该换电请求包括动力电池的第一BMU的物理地址的情况下，云端服务器可以将其发送至换电站的服务器。
通过上述一个或多个示例，在一些实际场景中，若动力电池可以在入仓前开始更新，即开始更新的时刻早于动力电池进入充电仓的时刻，可以进一步缩短充电时间，提高充电效率。
其次，对于S311的具体实施方式。第二BMU可以通过该无线通信链路获取到第一软件版本的版本信息之后，再将第一软件版本的版本信息发送至。在一些实施例中，第一软件版本的版本信息可以是在经过三次握手之后，第一BMU向第二BMU上报 的，或者是第一BMU基于第二BMU的请求发送至第二BMU的。
在第二个实施例中，第一软件版本的版本信息可以是信息读取装置从信息存储装置内读取得到的。其中，信息读取装置以及信息存储装置的具体内容可以参见本申请实施例的上述内容，对此不再赘述。
在第三个实施例中，信息读取装置从信息存储装置内读取得到的车辆、动力电池或者第一BMU的标识信息，然后基于该标识信息从换电站的服务器或者是云端服务器中预设的绑定关系中获取该标识信息对应的第一软件版本的版本信息。
第四个实施例中，第一软件版本的版本信息可以是第三BMU在建立与换电站的服务器的无线通信链路之后，通过该无线通信链路向换电站的服务器发送的。
第五个实施例中，第一软件版本的版本信息可以是云端服务器从车辆的换电请求中直接获取的，或者是根据换电请求中的车辆、动力电池或者第一BMU的标识信息确定的。
需要说明的是，本申请实施例还可以通过其他方式获取第一软件版本的版本信息，本申请对此不作具体限定。
在详细介绍了第一软件版本的具体内容之后，接下来，本申请实施例的下述部分对软件更新过程展开具体说明。
S320，在第一软件版本的版本信息低于存储于换电站的服务器的第二软件版本的版本信息的情况下，控制换电站的第二BMU将第一BMU的第一软件版本更新为第二软件版本，以基于第二软件版本对动力电池进行充电。
首先，对于第二软件版本，第二软件版本可以是希望动力电池统计更新的软件版本，比如，可以是最新版的软件版本，或者是bug数最少的软件版本，或者是安全性最高的软件版本等，对此不作具体限定。
其次，对于S320的具体实施方式。在一些实施例中，可以将第二软件版本的数据包发送至第二BMU，以使第二BMU基于该数据包对第一BMU进行更新。在一些示例中，可以提前将第二软件版本的数据包分发至各第二BMU，比如可以在换电控制器的第二软件版本更新之后，将更新后的第二软件版本的数据包发送至各第二BMU。在另一些示例中，可以在确定第一软件版本的版本信息低于第二软件版本的版本信息之后，将第二软件版本的数据包发送至第二BMU。
另外，对于第二BMU对第一BMU的软件更新方式。图5是本申请实施例提供的第三种动力电池的充电方法的流程示意图。图5与图3的不同之处在于，S320可以具体包括S321。
S321，通过第二BMU与第一BMU之间的无线通信链路，将第二软件版本的数据包发送给第一BMU，以使第一BMU的第一软件版本更新为第二软件版本。也就是说，换电站的服务器可以将第二软件版本的数据包发送至第二BMU，然后由第二BMU通过无线通信链路发送至第一BMU。
在一个示例中，该无线通信链路可以是蓝牙通信链路。无线通信链路的具体内容可以参见本申请上述实施例的相关内容，在此不再赘述。
相较于有线更新的方式，有线更新的方式必须是在动力电池进入充电仓且与第 二BMU插接好之后才能开始充电流程。而本实施例通过S321，第二BMU可以基于无线通信的方式对第一BMU进行更新，可以在动力电池进入充电仓前即可开始更新，且节省了有线插接的时间，提高了充电效率。
在另一个示例中，第二BMU还可以对第一BMU进行有线更新，本申请实施例对此不作具体限定。
通过本申请实施例提供的动力电池的充电方法，在安装有动力电池的车辆抵达换电站之后，换电站的服务器可以在动力电池的第一电池管理模块的第一软件版本的版本信息低于该服务器存储的第二软件版本的情况下，先将第一电池管理模块的第一软件版本更新至第二软件版本之后再对动力电池进行充电。通过本申请实施例，在充电前可以将第一软件版本更新至第二软件版本，避免了在充电时因软件版本过低需要暂停充电流程进行版本更新所导致的充电时间较长的问题，提高动力电池充电效率，进而提高用户使用体验。
另外，现阶段，由于在换电技术中大量动力电池会在不同的换电站之间流转，难以将各动力电池的第一BMU的软件版本统一更新至同一版本。而本申请实施例当动力电池进入换电站之后，可以通过换电站的服务器将动力电池的版本更新至第二软件版本，实现了对各动力电池的第一BMU的软件版本的统一。
在整体介绍了本申请实施例提供的动力电池的充电方法之后，由于第一BMU的软件版本随着时间以及根据需求而不断更新。在一些实施例中，为了能够保证动力电池更新后的软件版本的兼容性等因素，在具体换电场景中，需要根据需求对换电站的服务器内的第二软件版本的数据包进行灵活更新。接下来，本申请将通过四个实施例对换电站的服务器内的第二软件版本的数据包的更换过程展开详细说明。
在第一个实施例中，图6是本申请实施例提供的第四种动力电池的充电方法的流程示意图。图6与图5的不同之处在于，动力电池的充电方法还可以包括S331。
S331，周期接收云端服务器发送的第二软件版本的数据包。
在一个示例中，可以是云端服务器每间隔预设时长主动向换电站的服务器发送第二软件版本的数据包。比如，若第二软件版本是最新版，云端服务器可以每间隔预设时长确定已有的最新的软件版本，然后将已有的最新软件版本的数据包发送至换电站的服务器。其中，预设时长可以根据实际场景或者具体需求设置，比如可以几天或者一个月等。
在另一个示例中，可以是换电站的服务器每间隔预设时长之后向云端服务器发送第二软件版本的请求信息。云端服务器响应于该请求信息，向换电站的服务器返回的第二软件版本的数据包。
在第二个实施例中，图7是本申请实施例提供的第五种动力电池的充电方法的流程示意图。图7与图5的不同之处在于，动力电池的充电方法还可以包括S332和S333。
S332，基于车辆的换电预约请求，向云端服务器请求第二软件版本。
在一个示例中，换电站服务器可以在每次接收到接收到车辆的预约换电请求之后，向云端服务器请求第二软件版本。
在另一个示例中，换电站的服务器可以在第一软件版本的版本信息高于第二软件版本的版本信息的情况下，向云端服务器请求第二软件版本。
在实际场景中，由于某些原因(比如车辆刚从整车厂下线的，第一BMU的第一软件版本是当天更新的，挂牌后马上就来换电了；而第一BMU的升级包也是刚刚才发布到云端服务器的)导致换电站的服务器未及时更新第二软件版本，则车辆到换电站之后，换电站的服务器确定第一软件版本的版本信息高于第二软件版本的版本信息，则换电站的服务器可以向云端服务器请求第二软件版本。
S333，接收云端服务器发送的第二软件版本的数据包。
在第三个实施例中，为了保证换电站内的第二软件版本的及时性，动力电池的换电方法还包括：
步骤A1、当云端服务器上的第二软件版本更新之后，可以对换电站内的第二软件版本进行同步更新。
在第四个实施例中，为了进一步提高充电效率，动力电池的换电方法还包括：
步骤A2、云端服务器接收到车辆的预约换电请求以及换电站的服务器发送的第二软件版本。其中，预约换电请求包括车辆的动力电池的第一BMU的第一软件版本的版本信息。
步骤A3、若第一软件版本的版本信息低于云端服务器发送的第二软件版本的版本信息，且换电站的服务器内存储的第二软件版本的版本信息低于云端服务器内的第二软件版本的版本信息，则云端服务器向换电站的服务器发送第二软件版本的数据包。
需要说明的是，换电站的服务器还可以以其他方式对其存储的第二软件版本进行更新，对此不作具体限定。
另外，在一些实施例中，换电站的服务器获取云端服务器发送的第二软件版本的数据包之后，会用新接收的第二软件版本的数据包替换掉原有的第二软件版本的数据包。示例性地，若换电站的服务器中原先存储有版本A的数据包，云端服务器向换电站的服务器发送版本B的数据包之后，换电站的服务器会将版本B作为新的第二软件版本。
在一些实施例中，为了提高软件更新过程的安全性，图8是本申请实施例提供的第六种动力电池的充电方法的流程示意图。图8与图5的不同之处在于，动力电池的充电方法还包括：
S341，接收云端服务器发送的第一BMU的公钥。
在一些实施例中，云端服务器可以将可信电池的第一BMU的公钥发送至可信的换电站中。
S342，将第一BMU的公钥发送至第二BMU，以使第二BMU利用预先存储的换电站的私钥和第一BMU的公钥，对第二软件版本的数据包加密，得到密文数据；以及将密文数据发送至第一BMU，以使第一BMU基于换电站的公钥和第一BMU的私钥对密文数据解密，得到数据包。
在一些实施例中，可以使用第一BMU的公钥对数据包进行加密，得到数字签 名，然后利用换电站的私钥对该数字签名再次加密，得到待传输的密文数据。
相应地，在该密文数据传输至第一BMU支行，可以用换电站的公钥和第一BMU的私钥对该密文数据依次解密，得到数据包。
需要说明的是，通过本实施例，可以保证数据包传输过程的安全性，放置加密数据包被非法获取。并且，由于云端服务器会在可信的换电站和可信的动力电池之间进行秘钥互换，从而防止了非可信电池在换电站内的更新，以及防止非可信换电站对可信电池的更新，从而防止了私自换电等异常现象的产生，提高了换电流程的可靠性。
在一个示例中，本申请实施例的加密算法可以是对称加密算法，或者非对称加密算法，对此不作具体限定。示例地，可以是哈希算法。
在一些实施例中，为了提高软件更新过程的安全性，图9是本申请实施例提供的第七种动力电池的充电方法的流程示意图。图9与图5的不同之处在于，动力电池的充电方法还包括S351和S352。
S351，获取换电站的私钥和换电站的公钥。
S352，将换电站的私钥发送至第二BMU，以及将换电站的公钥发送至云端服务器，以供云端服务器将换电站的公钥分发至动力电池。
通过本申请实施例，可以将换电站的公钥分发给可信动力电池，保证了整个换电过程的可靠性。从而当可信动力电池接收到非法换电站伪造的密文数据之后，若使用换电站的公钥对无法其解密，从而可以暂停软件更新过程，提高了换电过程的可靠性。
通过上述实施例对软件更新过程展开具体说明之后，接下来将对软件更新之后的充电过程展开具体说明。
在一些实施例中，图10是本申请实施例提供的第八种动力电池的充电方法的流程示意图。图10与图3的不同之处在于，动力电池的充电方法还包括S361和S362。
S361，接收第二BMU发送的更新反馈信息，更新反馈信息表示第一BMU已将第一软件版本更新为第二软件版本。
在一个示例中，第一BMU基于数据完自身完成更新之后，会向第二BMU发送更新反馈信息。第二BMU接收到该更新反馈信息之后，会向换电站的服务器发送更新反馈信息。
S362，响应于更新反馈信息，启动利用第二软件版本对动力电池充电的充电流程。
在一个示例中，换电站的服务器可以向第二BMU发送启动软件更新的指令。第二BMU基于该指令，通过控制充电装置对动力电池进行充电。
基于相同的申请构思，本申请实施例除了提供了动力电池的充电方法之外，还提供了与之对应的动力电池的充电装置。
下面结合附图，详细介绍根据本申请实施例动力电池的充电装置。
