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。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。但现阶段,在换电站中需要人工操作换电站中的换电相关设备,换电效率仍然有待提高。
本申请实施例可提供一种车辆换电方法、换电站、车辆及系统,换电站能够根据车辆的车辆标识,使得换电站中的管理单元与车辆中的管理单元建立无线通信连接,从而通过无线通信连接进行交互,自动启动换电流程,实现换电站中换电的自动化,不需人工进行操作,以提高换电效率。
为了便于理解,下面先对本申请实施例提供的车辆换电方法的应用场景做示例性说明。图1为本申请实施例提供的车辆换电方法的应用场景的一示例的示意图。如图1所示,车辆换电方法可涉及换电站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。
在本申请实施例中,如图1所示,换电站11可包括第一管理单元111。在一些示例中,第一管理单元111可以为设置在换电站中的电池管理单元,例如,可称第一管理单元111为换电站的电池管理单元(Tube Battery Management Unit,TBMU)。第一管理单元111具有无线通信功能,能够与其他具有无线通信功能的单元、模块、装置等建立无线通信连接,并通过无线通信连接与其他具有无线通信功能的单元、模块、装置等进行交互。第一管理单元111的无线通信功能可包括蓝牙通信功能、WiFi通信功能、ZigBee通信功能等,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。
在本申请实施例中,车辆12具有第二管理单元121。在一些示例中,第二管理单元121可以为设置在车辆中的电池管理单元,例如,可称第二管理单元121为主电池管理单元(Master Battery Management Unit,MBMU)。第二管理单元121具有无线通信功能,能够与其他具有无线通信功能的单元、模块、装置等建立无线通信连接,并通过无线通信连接与其他具有无线通信功能的单元、模块、装置等进行交互。第二管理单元121的无线通信功能可包括蓝牙通信功能、WiFi通信功能、ZigBee通信功能等,在此并不限定。
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。换电站11中用于换电的电池可放置于换电站11的换电柜112中,在此并不限定。为了便于区分,如图1所示,车辆12内的电池记作电池131,换电站中用于换电的电池记作电池132。
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。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。
电池还可对应设置有第三管理单元133。在一些示例中,第三管理单元133可为与电池对应的电池管理单元,例如,可称第三管理单元133为从电池管理单元(Slave Battery Management Unit,SBMU)。第三管理单元133具有无线通信功能,能够与其他具有无线通信功能的单元、模块、装置等建立无线通信连接,并通过无线通信连接与其他具有无线通信功能的单元、模块、装置等进行交互。第三管理单元133的无线通信功能可包括蓝牙通信功能、WiFi通信功能、ZigBee通信功能等,在此并不限定。
如图1所示,当车辆12驶入换电站11,换电站11可将车辆12中电量不足的电池131取出,并将换电站11中电量充足的电池132安装至车辆12。电量充足的电池132安装至车辆12后,车辆12完成换电驶出换电站11。本申请实施例能够实现换电站11中换电的自动化,可以在几分钟、甚至数十秒内对车辆12完成换电,提高了换电效率。
在一些实施例中,换电站11还可对应设置有管理装置。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,管理装置还可部分设置在换电站11内,部分设置在换电站11外。管理装置可实现为换电站的站内内计算机和/或远程服务器等,在此并不限定。
图2为本申请实施例提供的车辆换电方法的应用场景的另一示例的示意图。图2与图1的不同之处在于,图2所示的应用场景还可包括换电站的站内计算机141和远程服务器142。站内计算机141可与第一管理单元111进行有线通信或无线通信,在此并不限定。站内计算机141可通过第一管理单元111和第二管理单元121获取车辆12内电池的相关信息和换电站11内用于换电的电池的相关信息,以及向第一管理单元111发送相关指令等。远程服务器142可与站内计算机141进行通信交互,以从站内计算机142获取车辆12内电池的相关信息和换电站11内用于换电的电池的相关信息,以及向站内计算机141发送相关指令等。
下面将对车辆换电方法、换电站、车辆及系统依次进行说明。
本申请第一方面提供一种车辆换电方法,可应用于换电站。换电站的具体内容可参见上述相关说明,在此不再赘述。下面以车辆中的电池为电池包为例进行说明。图3为本申请提供应用于换电站的车辆换电方法的一实施例的流程图。如图3所示,该车辆换电方法可包括步骤S201至步骤S204。
在步骤S201中,在目标车辆到达换电站的入口的情况下,采集目标车辆的车辆标识。
目标车辆可指待进行换电的车辆。车辆标识可用于标识车辆,即不同的车辆的车辆标识不同。车辆标识可包括车牌号码、车辆唯一标识码、车辆组成部件的产品序列号等,在此并不限定。车辆标识可设置在车辆外部,也可承载于射频识别(Radio  Frequency Identification,RFID)标签等可供读写的器件中,通过射频标签读写器可读取承载于射频识别标签中的车辆标识。在车辆标识承载于射频识别标签等可供读写的器件时,射频识别标签等可供读写的器件中还可存储车辆中第二管理单元的网络位置地址等其他信息,再此并不限定。射频识别标签等可供读写的器件中存储的至少部分信息可为加密后的信息,在此并不限定。对射频识别标签等可供读写的器件中的信息加密,可避免射频识别标签等可供读写的器件中的信息泄露,以保证车辆的信息安全。
在一些示例中,换电站的入口处可设置车辆标识采集装置,车辆标识采集装置可用于采集目标车辆的车辆标识。换电站的入口处还可设置采集区域,车辆标识采集装置具体可设置在采集区域的特定位置。车辆行驶至换电站的入口处,可停准在采集区域,以使得车辆标识采集装置能够采集到车辆标识。
例如,车辆标识为车牌号码,则车辆标识采集装置可为图像采集装置,通过图像采集装置如摄像头拍摄车牌号码,以对拍摄得到的车牌号码进行识别。又例如,车辆标识为车辆唯一标识码,车辆识别代码可存储于射频识别标签,射频识别标签可设置于车身或车辆内部,车辆标识采集装置可为射频识别标签读写器,在车辆停准在采集区域时,车辆的射频识别标签与车辆标识采集装置对准,使得车辆标识采集装置可读取射频识别标签中存储的信息。
在步骤S202中,根据目标车辆的车辆标识和存储的第一绑定关系,得到目标网络位置地址。
第一绑定关系包括车辆的车辆标识与车辆中第二管理单元的网络位置地址的对应关系。目标网络位置地址包括第一绑定关系中与目标车辆的车辆标识对应的第二管理单元的网络位置地址。即目标网络位置地址即为目标车辆中第二管理单元的网络位置地址。网络位置地址的类型可根据第一管理单元具有的无线通信功能和第二管理单元具有的无线通信功能设定,在此并不限定。例如,网络位置地址具体可包括媒体接入控制地址(Media Access Control Address,MAC地址)。
在一些示例中,换电站可对应设置有管理装置,第一绑定关系可存储于管理装置,管理装置的相关内容可参见上述相关说明,在此不再赘述。例如,管理装置包括站内计算机,则第一绑定关系可存储于站内计算机。又例如,管理装置可包括站内计算机和远程服务器,则第一绑定关系可存储于远程服务器,由远程服务器发送至站内计算器。可由管理装置根据目标车辆的车辆标识和存储的第一绑定关系,得到目标网络位置地址,将目标网络位置地址发送给第一管理单元。
在步骤S203中,基于目标网络位置地址,由第一管理单元向目标网络位置地址对应的第二管理单元发起无线通信请求。
在换电站获取到目标网络位置地址后,第一管理单元可利用目标网络位置地址向目标车辆的第二管理单元发起无线通信请求。无线通信请求用于请求与该第二管理单元建立无线通信连接。
第一管理单元利用第一绑定关系中与目标车辆的车辆标识对应的网络位置地址,向网络位置地址对应的第二管理单元发起无线通信请求,可避免与非法车辆中的 第二管理单元进行无线通信连接,进而避免为非法车辆进行换电,以保护合法车辆的换电权益。非法车辆可包括套牌车辆、非法组装的车辆等。
在步骤S204中,在第一管理单元与目标网络位置地址对应的第二管理单元成功建立无线通信连接的情况下,与目标网络位置地址对应的第二管理单元交互,以启动换电流程。
第一管理单元与目标网络位置地址对应的第二管理单元成功建立无线通信连接,即第一管理单元与目标车辆的第二管理单元成功建立无线通信连接后,第一管理单元与目标车辆的第二管理单元可进行交互。例如,第一管理单元可与该第二管理单元交互用于协助换电的信息或指令,如目标车辆中电池包的电池状态信息、电池包的充电参数信息、换电指令等,在此并不限定。
在本申请实施例中,换电站可根据目标车辆的车辆标识,得到在车辆标识与第二管理单元的网络位置地址的对应关系中与目标车辆的车辆标识对应的目标网络位置地址,即目标车辆的第二管理单元的网络位置地址。换电站中第一管理单元主动与目标车辆的第二管理单元建立无线通信连接,并可通过建立的无线通信连接交互,完成换电所需的信息、指令的交互,从而自动的启动换电流程。在目标车辆到达换电站入口后,换电站不需要人工操作,即可自动启动换电流程,提高了换电效率。
在一些实施例中,为了便于第一管理单元向目标车辆的第二管理单元发起无线通信连接,第一管理单元可切换为无线通信主节点模式。图4为本申请提供应用于换电站的车辆换电方法的另一实施例的流程图。图4与图3的不同之处在于,图4所示的车辆换电方法还可包括步骤S205,图3中的步骤S204可具体细化为图4中的步骤S2041至步骤S2043。
在步骤S205中,第一管理单元切换为无线通信主节点模式。
在得到目标网络位置地址之后,第一管理单元可切换为无线通信主节点模式。第一管理单元切换为无线通信主节点模式,可向处于无线通信从节点模式的装置、设备、部件等发起无线通信请求。处于无线通信主节点模式的第一管理单元作为无线通信的主节点,可向多个处于无线通信从节点模式的装置、设备、部件等发起无线通信请求,并可与多个处于无线通信从节点模式的装置、设备、部件等建立无线通信连接。
在一些示例中,换电站的第一管理单元切换为无线通信主节点模式,在多个车辆进入换电站的情况下,第一管理单元可向这多个车辆中的第二管理单元发起无线通信连接,并与这多个车辆中的第二管理单元建立无线通信连接。第一管理单元与每个车辆中的第二管理单元发起、建立无线通信连接的过程的具体内容可参见上述实施例中的相关说明,在此不再赘述。
在步骤S2041中,由第一管理单元向目标车辆的车辆标识对应的第二管理单元发送换电指令。
换电指令可用于指示换电。第二管理单元在接收到换电指令的情况下,开始执行换电流程的相关操作。
在步骤S2042中,由第一管理单元接收目标车辆的车辆标识对应的第二管理单 元发送的主从通信切换指令。
主从通信切换指令是目标车辆的车辆标识对应的第二管理单元响应于换电指令发送的。即目标车辆的第二管理单元在接收到换电指令的情况下,可向第一管理单元发送主从通信切换指令。
在步骤S2043中,响应于主从通信切换指令,第一管理单元由无线通信主节点模式切换为无线通信从节点模式。
由于在换电流程中,车辆的第二管理单元不仅需要与第一管理单元建立无线通信连接,还需与电池包的第三管理单元建立无线通信连接。即车辆的第二管理单元还需向电池包的第三管理单元发起无线通信请求,车辆的第二管理单元可切换为无线通信主节点模式,以便向第三管理单元发起通信连接请求。车辆的第二管理单元切换为无线通信主节点,对应地,第一管理单元可切换为无线通信从节点。因此,第一管理单元在接收到第二管理单元发送的主从通信切换指令的情况下,可由无线通信主节点模式切换为无线通信从节点模式。
随着无线通信技术的发展,有些无线通信技术不再限制只能由处于无线通信主节点模式的装置、设备、部件等发起无线通信请求,处于无线通信从节点模式的装置、设备、部件等也可发起无线通信请求。在本申请实施例中,第一管理单元、第二管理单元、第三管理单元等也可不进行无线通信主节点模式和无线通信从节点模式的切换,正常发起无线通信请求,建立无线通信连接即可,在此并不限定。
换电站的第一管理单元可与目标车辆的第二管理单元直接无线通信交互,实现换电流程的启动,不需要车辆整车配合与换电站进行通讯,适用性更强。
在一些实施例中,为了进一步保证换电站中对车辆的换电的安全性和可执行性,第二管理单元还可提供用于协助换电的电池包的相关信息,保证换电正常进行。图5为本申请提供应用于换电站的车辆换电方法的又一实施例的流程图。图5与图3的不同之处在于,图3中的步骤S204可具体细化为图5中步骤S2044和步骤S2045。
在步骤S2044中,由第一管理单元从与目标网络位置地址对应的第二管理单元获取换电准备信息。
换电准备信息是电池包为换电所采取的准备措施的相关信息,具体可根据车辆和换电站的需求、经验等选取,在此并不限定。换电准备信息由第二管理单元从目标车辆的电池包的第三管理单元获取。第二管理单元可与第三管理单元建立无线通信连接,通过交互,从第三管理单元获取电池包的换电准备信息。在进入换电站,车辆的第二管理单元可与车辆中待换的电池包的第三管理单元建立无线通信连接的情况下,第三管理单元可周期性向第二管理单元发送换电准备信息,或者,在电池包的换电准备信息发生变化时第三管理单元向第二管理单元发送换电准备信息,在此并不限定。
在步骤S2045中,在换电准备信息满足预设的换电准备安全条件的情况下,由第一管理单元向与目标车辆的车辆标识对应的第二管理单元发送换电指令。
换电准备安全条件为用于判定车辆的电池包换电准备是否安全的条件,可根据车辆和电池包的需求、经验等设置,在此并不限定。换电准备信息满足换电准备安全条件,表示车辆的电池包换电准备安全,可对车辆的电池包进行更换。第一管理单元 可将换电准备信息上传至换电站的管理装置,由管理装置确定换电准备信息是否满足换电准备安全条件,并在换电准备信息满足换电准备安全条件的条件下,控制第一管理单元向第二管理单元发送换电指令。
在一些示例中,换电准备信息可包括电池包的继电器的通断状态和电池包的换电锁结构的开关状态。换电准备安全条件包括:电池包的继电器的通断状态为断开状态,电池包的换电锁结构的开关状态为解锁状态。电池包的继电器的通断状态为断开状态,表示车辆已下电。电池包的继电器可包括电池包内的支路继电器、车辆与电池包对应的主回路继电器,在此并不限定。电池包的换电锁结构的开关状态为解锁状态,表示电池包可从车辆取出。
通过换电准备信息和换电准备安全条件,使得在目标车辆的电池包换电准备安全的情况下,才执行换电流程,从而保证了换电的安全性和可靠性。
在一些实施例中,还可对目标车辆进行身份验证,以保证换电的可靠性和可控性。图6为本申请提供应用于换电站的车辆换电方法的再一实施例的流程图。图6与图3的不同之处在于,图6所示的车辆换电方法还可包括步骤S206和步骤S207,图3中的步骤S202可具体细化为步骤S2021。
在步骤S206中,在预先获取的换电权限名单中查询目标车辆的车辆标识。
换电权限名单中包括具有换电权限的车辆的车辆标识。在换电权限名单中查询目标车辆的车辆标识,以确定目标车辆是否具有换电权限。换电权限名单可存储在换电站的管理装置中,由管理装置在换电权限名单中查询目标车辆的车辆标识。可由站内计算机执行在换电权限名单中查询目标车辆的车辆标识,或者,可由远程服务器执行在换电权限名单中查询目标车辆的车辆标识。
在步骤S207中,在换电权限名单中存在目标车辆的车辆标识的情况下,允许目标车辆进入换电站。
换电权限名单可包括提前进行预约换电的车辆的车辆标识、开通换电业务的车辆的车辆标识等。若换电权限名单中存在目标车辆的车辆标识,表示目标车辆具有换电权限,允许目标车辆进行入换电站。若换电权限名单中不存在目标车辆的车辆标识,表示车辆不具有换电权限,不允许目标车辆进入换电站。
换电站可设置道闸,该道闸可由换电站的管理装置控制。在管理装置确定换电权限名单中存在目标车辆的车辆标识的情况下,管理装置可控制道闸开启,以供目标车辆进入换电站。在管理装置确定换电权限名单中不存在目标车辆的车辆标识的情况下,管理装置可控制道闸关闭,拒绝目标车辆进入换电站。
在步骤S2021中,在换电权限名单中存在目标车辆的车辆标识的情况下,根据目标车辆的车辆标识和预存的第一绑定关系,得到目标网络位置地址。
在确定目标车辆具有换电权限的情况下,才允许获取目标网络位置地址,从而使得换电站的第一管理单元能够与目标车辆的第二管理单元建立无线通信连接。
通过换电权限名单来确定目标车辆是否有换电权限,换电站只允许具有换电权限的车辆进入,能够保证换电流程的可靠性和可控性。
在一些实施例中,换电站中可包括多个换电区域,在目标车辆达到换电站 的入口的情况下,还可确定换电站中是否具有空闲的换电区域,若换电站具有空闲的换电区域,允许目标车辆进入换电站;若换电站不具有空闲的换电区域,拒绝目标车辆进入换电站。
本申请第二方面提供一种车辆换电方法,可应用于车辆中的第二管理单元。车辆和第二管理单元的具体内容可参见上述相关说明,在此不再赘述。下面以车辆中的电池为电池包为例进行说明。图7为本申请提供应用于第二管理单元的车辆换电方法的一实施例的流程图。如图7所示,该车辆换电方法可包括步骤S301和步骤S302。
在步骤S301中,在车辆进入换电站后,接收换电站中第一管理单元发送的无线通信请求。
无线通信请求由第一管理单元基于获取到的目标网络位置地址发送。目标网络位置地址为换电站中存储的第一绑定关系中与车辆的车辆标识对应的网络位置关系。第一绑定关系包括车辆的第二管理单元的网络位置地址与车辆的车辆标识的对应关系。
无线通信请求、目标网络位置地址、第一绑定关系等具体内容可参见上述实施例中的相关说明,在此不再赘述。
在步骤S302中,响应于无线通信请求,与换电站中第一管理单元建立无线通信连接,与换电站中第一管理单元交互,以启动换电流程。
第二管理单元与换电站的第一管理单元成功建立无线通信连接后,第二管理单元与换电站的第一管理单元可进行交互。例如,第二管理单元可与该第一管理单元交互用于协助换电的信息或指令,如目标车辆中电池包的电池状态信息、电池包的充电参数信息、换电指令等,在此并不限定。
在一些示例中,可设置无线通信连接建立的超时时间阈值,若在该超时时间阈值内第二管理单元与第一管理单元建立起无线通信连接,即认为第二管理单元与第一管理单元成功建立无线通信连接;若在该超时时间阈值内第二管理单元与第一管理单元未建立起无线通信连接,认为第二管理单元与第一管理单元无线通信连接建立失败。该超时时间阈值可根据场景、需求、经验等设定,在此并不限定。例如,超时时间阈值可为10秒。
若第二管理单元与第一管理单元成功建立无线通信连接,第二管理单元可保持上电状态,以启动换电流程。若第二管理单元与第一管理单元无线通信连接建立失败,第二管理单元可进入下电状态或休眠状态,以节省电能。
在本申请实施例中,换电站中第一管理单元可通过第一绑定关系,获取到车辆的车辆标识对应的目标网络位置地址。车辆的第二管理单元可接收换电站的第一管理单元根据目标网络位置地址主动发起的无线通信请求,以与该第一管理单元建立无线通信连接。第二管理单元与第一管理单元可通过建立的无线通信连接交互,完成换电所需的信息、指令的交互,从而自动的启动换电流程。在目标车辆到达换电站入口后,换电站不需要人工操作,即可自动启动换电流程,提高了换电效率。
在一些实施例中,为了便于第一管理单元向目标车辆的第二管理单元发起 无线通信连接,第一管理单元可切换为无线通信主节点模式,对应地,第二管理单元可切换为无线通信从节点模式。图8为本申请提供应用于第二管理单元的车辆换电方法的另一实施例的流程图。图8与图7的不同之处在于,图8所示的车辆换电方法还可包括步骤S303,图7中的步骤S302可具体细化为图8中的步骤S3021至步骤S3023。
在步骤S303中,第二管理单元切换为无线通信从节点模式。
在车辆进入换电站,为了配合换电,车辆需要下电。在车辆未下电前,第二管理单元可处于无线通信主节点模式,并与车辆的电池包的第三管理单元无线通信连接,此时第三管理单元处于无线通信从节点模式。在车辆下电的情况下,在第一管理单元得到第二管理电源的网络位置地址后,第一管理单元可切换为无线通信主节点模式,主动发起无线通信请求。第二管理单元需要与第一管理单元建立无线通信连接,第二管理单元可先断开与第三管理单元的无线通信连接,然后切换为无线通信从节点模式以接收并响应第一管理单元发起的无线通信请求,与处于无线通信主节点模式的第一管理单元建立无线通信连接。
在步骤S3021中,由第二管理单元接收第一管理单元发送的换电指令。
换电指令用于指示启动换电流程。第二管理单元接收到换电指令的情况下,可执行换电流程的相关操作。
在步骤S3022中,响应于换电指令,第二管理单元切换为无线通信主节点模式。
在换电流程中,第二管理单元需要从电池包的第三管理单元获取电池包的用于协助换电的信息,因此第二管理单元需要与第三管理单元建立无线通信连接。对应地,第二管理单元可切换为无线通信主节点模式,以主动向第三管理单元发起无线通信请求,实现与第三管理单元的无线通信连接。
在步骤S3023中,由第二管理单元向第一管理单元发送主从通信切换指令。
第二管理单元切换为无线通信主节点模式,对应地,需要与第二管理单元无线通信连接的第一管理单元和第三管理单元需要切换为无线通信从节点模式。主从通信切换指令用于指示第一管理单元切换为无线通信从节点模式。通过主从通信切换指令使第一管理单元切换为无线通信从节点模式。
第二管理单元切换为无线通信主节点模式,第二管理单元可主动搜索处于无线通信从节点模式的第一管理单元和第三管理单元的网络位置地址,从而与第一管理单元和第三管理单元建立无线通信连接。
随着无线通信技术的发展,有些无线通信技术不再限制只能由处于无线通信主节点模式的装置、设备、部件等发起无线通信请求,处于无线通信从节点模式的装置、设备、部件等也可发起无线通信请求。在本申请实施例中,第一管理单元、第二管理单元、第三管理单元等也可不进行无线通信主节点模式和无线通信从节点模式的切换,正常发起无线通信请求,建立无线通信连接即可,在此并不限定。
车辆的第二管理单元可与换电站的第一管理单元直接无线通信交互,实现 换电流程的启动,不需要车辆整车配合与换电站进行通讯,适用性更强。
在一些实施例中,为了提高换电的安全性,第二管理单元可在确定车辆下高压的情况下,再与第一管理单元建立无线通信连接,以启动换电流程。图9为本申请提供应用于第二管理单元的车辆换电方法的又一实施例的流程图。图9与图7的不同之处在于,图9所示的车辆换电方法还可包括步骤S304,图7中的步骤S301可具体细化为图9中的步骤S3011。
在步骤S304中,由第二管理单元从车辆的整车控制器获取车辆下高压状态信息。
整车控制器可对车辆的下高压状态进行监控,并生成下高压状态信息。下高压状态信息可表征车辆是否已下高压。
在步骤S3011中,在车辆下高压状态信息表征车辆已下高压的情况下,接收换电站中第一管理单元发送的无线通信请求。
在车辆已下高压的情况下,第二管理单元才会与第一管理单元建立无线通信连接,以及启动换电流程,以保证换电的安全性和可靠性。
在一些实施例中,为了进一步保证换电站中对车辆的换电的安全性和可执行性,第二管理单元还可获取并提供用于协助换电的电池包的相关信息。图10为本申请提供应用于第二管理单元的车辆换电方法的再一实施例的流程图。图10与图7的不同之处在于,图10所示的车辆换电方法还可包括步骤S305和步骤S306,图7中的步骤S302可具体细化为图10中的步骤S3024。
在步骤S305中,由第二管理单元向目标车辆的电池包的第三管理单元发起无线通信请求。
第三管理单元具有无线通信功能,可用于监控电池包状态信息。电池包状态可包括电池包的换电准备信息。第三管理单元、换电准备信息等的具体内容可参见上述实施例中的相关说明,在此不再赘述。
在步骤S306中,在第二管理单元与第三管理单元成功建立无线通信连接的情况下,由第二管理单元从第三管理单元获取换电准备信息,并向第一管理单元发送。
在步骤S3024中,在换电准备信息满足预设的换电准备安全条件的情况下,由第二管理单元接收第一管理单元发送的换电指令
在一些示例中,换电准备信息包括电池包的继电器的通断状态和电池包的换电锁结构的开关状态。换电准备安全条件包括:电池包的继电器的通断状态为断开状态,电池包的换电锁结构的开关状态为解锁状态。
换电准备安全条件、换电准备信息等的具体内容可参见上述实施例中的相关说明,在此不再赘述。
通过换电准备信息和换电准备安全条件,使得在目标车辆的电池包换电准备安全的情况下,才执行换电流程,从而保证了换电的安全性和可靠性。
