随着新能源技术的发展，电池的应用领域越来越广泛，如可作为动力源为车辆提供动力，减少不可再生资源的使用。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。或者，也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电池存放机构中进行充电，以备为后续进入换电站的车辆进行换电。
电池在使用了一段时间或一定循环圈数后，电池的性能可能会发生改变，例如电池的健康状态(state of health，SOH)，可能会随着电池的使用而产生衰减。如果仍然按照新电池的SOH来计算该电池的费用，则会造成计费不准确，给用户或运营商带来损失。另外，随着电池的使用，电池的荷电状态(state of charge，SOC)也有可能因为误差的积累而导致测量结果的不准确，如果仍然按照该电池直接测量得到的SOC进行计费，同样会造成计费不准确，给用户或运营商带来损失。
鉴于此，本申请实施例提供了一种用于电池换电的方法，通过获取电池在使用过程中净消耗的电量，并根据该电量进行计费，可以免第一电池在使用过程中电池参数的变化导致的计费误差，从而实现合理计费，有利于提高计费的准确性。
图1示出了本申请实施例的更换电池的方法的应用场景的一种示意图。如图1所示，该更换电池的方法的应用场景可涉及到换电站11、车辆12和电池。
换电站11可指为车辆提供换电服务的场所。例如，换电站11可以为固定的场所，或者，换电站11可为如移动换电车辆等可移动场所，在此并不限定。
车辆12可与电池可拆卸连接。在一些示例中，车辆12可以是小汽车、货车等以动力电池为动力源的车辆。
电池可包括设置在车辆12内的电池和位于换电站11中用于换电的电池。为了便于区分，如图1所示，车辆12内待更换的电池记作电池141，换电站中用于换电的电池记作电池142。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。电池除了可作为动力源为车辆12的电机供电，还可为车辆12中的其他用电器件供电，例如，电池还可为车内空调、车载播放器等供电。
当安装有电池141的车辆12驶入换电站11之后，换电站11通过换电装置将电池141从车辆12取下，并从换电站11中取出电池142，然后将电池142安装到车辆12上。之后安装有电池142的车辆12可以驶离换电站11。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。
如图1所示，换电站11中可设置有换电柜13。换电柜13包括第一电池管理单元131和充电单元132。换电柜13还可设置有多个充电仓133，用于换电的电池可放置于换电站11的换电柜13的充电仓133中。第一电池管理单元131可为设置在换电柜13中的电池管理单元，例如，可称第一电池管理单元131为中心电池管理单元(Central Battery Management Unit，CBMU)。充电单元132可对充电仓133中的电池充电。在一些示例中，充电单元可包括交流/直流模块即AC/DC模块等具有充电功能的部件、装置或设备，在此并不限定。充电单元132可与充电仓133一一对应设置，也可多个充电仓133共用一个充电单元132，在此并不限定。
电池可对应设置有第二电池管理单元143。例如，可称第二电池管理单元143为从电池管理单元(Slave Battery Management Unit，SBMU)。
车辆12上还设置有第三电池管理单元121。该第三电池管理单元121可用于管理车辆上安装的多个电池141，例如，可称第三电池管理单元121为主电池管理单元(Main Battery Management Unit，MBMU)。
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。
换电站11还可对应设置有管理装置。该管理装置可为集中式结构，也可为分布式结构，在此并不限定。管理装置可设置在换电站11内，也可以设置在换电站11外。在管理装置为分布式结构的情况下，管理装置还可以部分设置在换电站11内，部分设置在换电站11外。例如，如图1所示，管理装置可以包括换电站11内的站控系统151和换电站11外的云端服务器152，在此并不限定。站控系统151也可以称为是换电站11中的电池管理单元，用于对换电站11中的电池142进行管理控制。
可选地，第一电池管理单元131可通过有线或无线方式与其他单元、模块、装置等进行通信交互。第二电池管理单元143可通过有线或无线方式与其他单元、模块、装置等进行通信交互。第三电池管理单元121可通过有线或无线方式与其他单元、模块、装置等进行通信交互。站控系统151可通过有线或无线方式与其他单元、模块、装置等进行通信交互。有线通信方式包括例如CAN通信总线。无线通信方式包括例如 蓝牙通信、WiFi通信、ZigBee通信等各种方式，在此并不限定。
例如，第一电池管理单元131可以与第二电池管理单元143之间进行通信，以控制对电池仓133内的电池142进行充电。再例如，第三电池管理单元121可以与第二电池管理单元143之间进行通信，以集中管理车辆12上的多个电池141。再例如，站控系统151可以与第一电池管理单元131、第二电池管理单元143或第三电池管理单元121之间进行通信，以获取车辆12上的电池141或充电仓133内的电池142的相关信息。再例如，站控系统151也可以与云端服务器152之间进行通信，以获取车辆12上的电池141或充电仓133内的电池142的相关信息。
在将旧电池从用电设备换下，将新电池为用电设备换上后，换电设备可以对该次换电进行计费，其中用电设备例如可以是图1中的车辆12。本申请提供了一种用于电池换电的方法，如图2所示。图2中示出的方法200可以由站控系统执行，例如图1中的站控系统151。可选地，方法200也可以应用于服务器、电池管理系统、换电设备等能够对电池的相关参数进行处理的装置。应理解，本申请对执行方法200的装置不做限定，即可以对电池的相关参数进行处理的装置均适用于本申请实施例。方法200可以包括以下内容中的至少部分内容。
S210：获取第一电池在从被换上至用电设备到从所述用电设备换下的使用过程中的放电电量。
S220：根据所述放电电量进行计费。
第一电池为用电设备中已使用的旧电池，在换电过程中需要换电设备将第一电池换下，再为用电设备换上新电池。在用电设备完成电池的更换后，换电站中的站控系统需要对该次换电进行计费。为了避免第一电池在使用过程中电池参数发生变化而导致计费不准确，在对第一电池的换电过程进行计费时，可以通过记录第一电池实际消耗的电量来进行计费。
放电电量可以看作是第一电池的净消耗电量，指的是第一电池消耗的电量中除去了使用过程中的增加电量的部分，该放电电量也即为用于计费的电量。
在一种可能的实施方式中，放电电量可以由第一电池的BMS确定。BMS通过安时积分法记录第一电池在使用过程中的消耗的容量和增加的容量，计算出第一电池实际的放电电量，并将放电电量发送给站控系统。
在另一种可能的实施方式中，放电电量可以由站控系统确定。BMS通过安时积分法记录第一电池在使用过程中的消耗的容量和增加的容量，并将这些直接获取到的容量发送给站控系统，由站控系统计算第一电池实际的放电电量。
在用电设备换上电池的数量和换下电池的数量不同的情况下，例如，用电设备换下了一块第一电池并换上了多块第二电池，则可以按照方法200对第一电池实际消耗的电量进行计费，另外再根据换上电池的数量，或者，换下电池的数量，或者，第一电池和第二电池之间的数量差，来确定用户使用电池的基础费用。若用电设备换下了多块第一电池且仅换上了一块第二电池，可以分别对每一块第一电池进行计费，再根据第一电池和第二电池的数量，确定用户使用电池的基础费用。
通过获取第一电池在使用过程中的放电电量，可以直接根据第一电池净消耗的电量进行计费，能够避免第一电池在使用过程中电池参数的变化导致的计费误差，从而实现合理计费，有利于提高计费的准确性。
根据本申请的一些实施例，可选地，步骤S210可以包括：站控系统获取第一电池的路途放电容量，路途放电容量为第一电池在使用过程中被记录的放电容量；站控系统根据路途放电容量确定放电电量。
路途放电容量指的是用电设备在使用第一电池的过程中，当有放电电流通过第一电池时，被记录的放电容量。例如，可以由BMS利用安时积分法对第一电池在放电过程中的放电容量进行记录。安时积分法即为在一定时间内对电流进行积分来计算出该段时间内电池消耗或累积的容量的方法。在本申请实施例中，在第一电池放电的时间范围内对经过第一电池的放电电流进行积分，则能够获取第一电池的路途放电容量。
在第一电池的使用过程中，可能仅涉及到路途放电容量，则可以将路途放电容量换算为路途放电电量，以作为放电电量来进行计费。
在一种可能的实施方式中，站控系统获取第一电池的路途放电容量时，可以执行步骤S301，从第一电池的BMS，接收路途放电容量。
以路途放电容量来确定第一电池的放电电量，可以直接将第一电池消耗的电量作为放电电量进行计费，可以避免第一电池的电池参数变化对计费的准确性的影响，从而能够实现合理计费，提高计费的准确性。
根据本申请的一些实施例，可选地，方法200还包括：站控系统获取第一电池的路途充电容量，路途充电容量为第一电池在使用过程中被记录的充电容量。站控系统根据路途放电容量和路途充电容量确定放电电量。
考虑到用户在使用第一电池的过程中，有可能会利用充电设备对第一电池进行充电，例如，利用充电桩对第一电池进行充电。为了计费的合理性，用户自行充电的这部分电量不应算在对换电过程的计费中，因此在对换电过程进行计费时，可以考虑减去用户已经对第一电池进行充电的部分。
在一种可能的实施方式中，第一电池的路途充电容量也可以由BMS利用安时积分法进行记录，即，在充电的时间范围内对充电电流进行积分，来计算充电时间内电池累积的容量。
在对换电过程进行计费时，可以将路途放电容量减去路途充电容量，再换算成电量，即为用于计费的放电电量。
在一种可能的实施方式中，站控系统获取第一电池的路途充电容量时，可以执行步骤S302，从第一电池的BMS，接收路途充电容量。
通过考虑用户自行对充电设备进行充电的电量，可以避免对这部分电量重复收费，使得收费方式更加合理准确。
根据本申请的一些实施例，可选地，方法200还包括：站控系统获取第一电池的路途回收容量，路途回收容量为第一电池在使用过程中被记录的回收容量。站控系统根据路途放电容量和路途回收容量确定放电电量。
在一些可能的情况下，用电设备在使用第一电池的过程中可能会产生一定的能量回收，例如，用电设备为电动汽车的情况下，电动汽车减速时可以通过电机制动来发电，这部分电量就会被回收至第一电池。则在对第一电池的换电过程进行计费时，需要考虑将回收的电量排除在用于计费的电量之外。
具体地，第一电池的路途回收容量也可以由BMS利用安时积分法进行记录，即，在有回收电量的电流经过第一电池时，BMS对这段时间内的电流进行积分，来计算电池累积的容量。
在对换电过程进行计费时，可以将路途放电容量减去路途回收容量，再换算成电量，即为用于计费的放电电量。
在一种可能的实施方式中，站控系统获取第一电池的路途回收容量时，可以执行步骤S303，从第一电池的BMS，接收路途回收容量。
通过考虑用电设备在使用过程中产生的路途回收电量，可以避免对这部分电量额外收费，使得收费方式更加合理准确。
根据本申请的一些实施例，可选地，方法200还包括：站控系统获取第一电池的路途放电容量、路途充电容量和路途回收容量，路途放电容量为第一电池在使用过程中被记录的放电容量，路途充电容量为第一电池在使用过程中被记录的充电容量，路途回收容量为第一电池在使用过程中被记录的回收容量。其中步骤S220可以包括：根据路途放电容量、路途充电容量和路途回收容量确定放电电量。
在第一电池的使用过程中，如果同时存在用户为第一电池充电以及用电设备产生了能力回收，则在对第一电池的换电过程进行计费时，需要将上述两种情况产生的电量均排除在外。
如图3所示，站控系统可以执行步骤S304，根据接收到的相关参数进行计费，在与计费有关的电池参数均换算为电量的情况下，路途放电电量减去路途充电电量和路途回收电量，则为第一电池在使用过程中的实际放电电量，该放电电量则为本次换电过程用于计费的放电电量。
充分考虑第一电池在使用过程中可能会消耗电量或累积电量的情况，仅对实际消耗的电量中未收费的部分进行计费，也不对额外累积的电量进行计费，这样有利于实现合理计费，提高计费的准确性。
根据本申请的一些实施例，可选地，根据以下公式(1)计算放电电量。
Figure PCTCN2022104213-appb-000003
其中，H为放电电量，E 1为第一电池的总电量，C为路途放电容量，D为路途充电容量，E为路途回收容量，M为第一电池的总容量。
放电电量即为用于计费的电池电量，例如，可以将放电电量与电量单价相乘，来获取计费结果。公式(1)考虑了第一电池的使用过程包括用户为第一电池充电以及用电设备存在回收电量的情况，在用户没有为第一电池充电或用电设备不存在回收电量的情况下，相应参数可以为0。
通过充分考虑在第一电池的使用过程中用户可能会对第一电池充电，以及用电设备本身可能会回收电量的情况来计算用于计费的结算电量，能够使得计费过程更加合理，从而提高计费的准确性。
本申请还提供了一种用于电池换电的方法400，如图4所示，可以应用于电池管理系统，电池管理系统可以例如是第一电池的BMS，即该电池管理系统始终跟随着电池的；也可以是通过外部接口与第一电池连接的BMS，即仅在需要对电池的相关参数进行测量时接入第一电池。可选地，方法400也可以应用于服务器、换电设备等能够对电池的相关参数进行处理的装置。应理解，本申请对执行方法400的装置不做限定，即可以对电池的相关参数进行处理的装置均适用于本申请实施例。本申请实施例仅以应用于第一电池的BMS为例进行说明，方法400可以包括以下内容中的至少部分内容。
S410：获取第一电池的路途放电容量，路途放电容量为第一电池在从被换上至用电设备到从所述用电设备换下的使用过程中被记录的放电容量。
S420：发送路途放电容量，路途放电容量用于确定第一电池在使用过程中的放电电量，放电电量用于计费。
