附图说明
为了更清楚地说明本申请实施例的技术方案,下面将对本申请实施例中所需要使用的附图作简单地介绍,显而易见地,下面所描述的附图仅仅是本申请的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据附图获得其他的附图。
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;

图4是本申请实施例提供的第一种换电方法的流程示意图;

图6示出了本发明实施例提供的换电设备的硬件结构示意图。
在附图中,附图并未按照实际的比例绘制。
具体实施方式
下述描述中出现的方位词均为图中示出的方向,并不是对本申请的具体结构进行限定。在本申请的描述中,还需要说明的是,除非另有明确的规定和限定,术语“安装”、“相连”、“连接”应做广义理解,例如,可以是固定连接,也可以是可拆卸连接,或一体地连接;可以是直接相连,也可以通过中间媒介间接相连。对于本领域的普通技术人员而言,可视具体情况理解上述术语在本申请中的具体含义。
下面将详细描述本申请的各个方面的特征和示例性实施例,为了使本申请的目的、技术方案及优点更加清楚明白,以下结合附图及具体实施例,对本申请进行进一步详细描述。应理解,此处所描述的具体实施例仅意在解释本申请,而不是限定本申请。对于本领域技术人员来说,本申请可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本申请的示例来提供对本申请更好的理解。
需要说明的是,在本文中,诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来,而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下,由语句“包括……”限定的要素,并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
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,车辆达到换电站之后,换电站会确定是否有足量的可用电池。如果换电站不能提供足够的可用电池包提供给用户,则需要车辆等待换电站充电或者寻找其他换电站,影响用户的换电体验。示例性地,在换电站不足以满足汽车的换电需求的具体应用场景下,可能会造成诸如车辆到达换电站之后才发现换电站没有可用电池需要寻找其他换电站,或者到达换电站之后发现需要等待很长一段时间,影响用户的使用体验。
因此需要一种能够提高用户使用体验的技术方案。
基于此,本申请实施例提供了换电方法、装置、设备和介质,可以应用到车辆在换电站更换电池的应用场景中。示例性的,可以具体应用于车辆预约换电的具体应用场景中。与上述相关技术相比,能够响应于车辆的换电请求,根据车辆的预约换电时间以及预约换电量为用户推荐换电时间以及推荐换电量,以使用户可以根据推荐换电时间以及推荐换电量提前确定是否换电,避免了到站之后发现可用电池数量不足的现象,从而提高了用户的使用体验。
为了更好的理解本申请,在开始介绍本申请实施例提供换电方案之前,本申请实施例先依次对本申请涉及的车辆、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)电池,本申请实施例中的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,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,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换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通过换电装置将第一电池P1从车辆11取下,并从充电仓122中取出第二电池P2,然后将第二电池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换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***展开具体说明。
图2是本申请实施例提供的一种换电***的***框架图。如图2所示,换电***10可以包括车辆的终端设备21和换电站服务器22。
首先,对于车辆的终端设备21,其可以包括具有外部通讯功能的设备或者模块。比如,车辆的终端设备21可以是手机、智能手表、电脑、平板电脑、车载通讯设备等具备通讯功能的设备。
在一些示例中,车辆的终端设备21可以包括诸如远程信息处理器(Telematics BOX,TBOX)或者RDB(一种车联网设备)等车联网设备。比如,用户可以通过手机APP发起换电请求,然后经过车联网设备将该请求发送至换电站服务器22。又比如,用户在车辆的控制屏等信息输入设备上发起换电请求,比如用户点击触控屏幕上的“换电”控件,然后信息输入设备将该换电请求通过车联网设备发送至换电站服务器22。
其次,对于换电站服务器22,其可以具备通信功能以及计算功能。
再其次,车辆的终端设备21和换电站服务器22之间可以联网通信,比如可以利用全球移动通信***(Global System for Mobile Communications,GSM)网络、***移动通信技术(the 4th generation mobile communication technology,4G)等数据传输网络,蓝牙、紫蜂等近距离无线通信技术进行通信,对此不作具体限定。
图3是本申请实施例提供的另一种换电***的***框架图。图3与图2的不同之处在于,换电***20还可以包括云端服务器23,以及,车辆的终端设备21和云端服务器23之间可以互相通信,云端服务器23与换电站服务器22之间可以互相通信。其中,上述设备之间可以通过上述数据传输网络通信,在此不再赘述。

在一些实施例中,车辆的终端设备21还可以与换电站服务器22之间通信,其具体通信方式可见本申请实施例的上述内容,在此不再赘述。
在充分介绍了换电***之后,接下来,本申请实施例的下述部分将结合附图, 详细描述根据本申请实施例的换电方法、装置、设备和介质,应注意,这些实施例并不用来限制本申请公开的范围。
图4是本申请实施例提供的第一种换电方法的流程示意图。图4中各步骤的执行主体可以是诸如换电站服务器或者是云端服务器等具有计算能力的换电装置,对此不作具体限定。
如图4所示,换电方法包括S410至S430。
S410,接收车辆的换电请求。
首先,对于车辆。本申请实施例中的车辆可以安装有至少一个电池包,关于本申请实施例中车辆的其他内容可参见本申请上述实施例的相关说明,在此不再赘述。
其次,对于换电请求。
从请求发送方而言。在一些实施例中,换电请求可以是用户在车联联网设备的触控屏或者用户在手机等移动终端设备上的预约换电应用程序(application,APP)或者预约换电网页上发起的。在另一些实施例中,换电请求可以是在车辆在抵达换电站之后换电站服务器发送的换电请求。
从换电请求的具体含义而言。本申请实施例的换电请求表示车辆请求在换电站内更换电池。具体地,本申请实施例中的换电请求包括第一换电时间和第一换电量,第一换电时间为预约换电时间,第一换电量为预约换电量。相应地,包含有第一换电时间和第一换电量的换电请求表示车辆请求在第一换电时间更换上电量为第一换电量的一个或者多个电池。相应地,在一个示例中,换电请求可以包括第一换电时间16:40,第一换电量80%,也就是说,该换电请求表示车辆请求在16:40分更换上电量为80%SOC的电池。
接下来,针对第一换电量以及第一换电时间展开具体说明。
第一、针对二者的具体含义,说明如下。
针对第一换电时间T1,其可以为预约换电时间。其中,第一换电时间T1可以是指定的目标换电时间,也就是说,用户希望在该该换电时间进行换电。又或者,可以是用户可以接受的最晚换电时间。又或者可以是用户达到换电站的最早时间。本申请对第一换电时间T1的具体含义不作限定。
在一个示例中,第一换电时间的形式可以包括具体的换电时刻,比如“小时:分:秒”的形式。又或者,还可以包括具体的年月日,对其形式不作具体限定。在又一个示例中,第一换电时间可以表示车辆在多长时间之后请求换电。比如,若第一换电时间为50分钟(min),则表示车辆在50min之后,请求换电。其中,可以是距离车辆发起换电请求多久之后请求换电,又或者可以是距离该换电请求的响应时刻多久之后请求换电。本申请实施例第一换电时间T1的具体形式可以根据实际场景和具体需求设置,对此不作具体限定。
在另一些实施例中,针对第一换电量C1,其可以为预约换电量。即车辆需要换电站为其提供的。第一换电量C1可以是指定的目标换电量,也就是说,用户希望更换上该电量的电池。又或者,可以是用户可以接受的最小电池电量。又或者可以是用户接受的最大电池电量。本申请对第一换电量C1的具体含义不作限定。示例性地,第一换电量C1可以为表示电池电量的参数,比如电池的荷电状态(State Of Charge,SOC)或者是电池的电量Q。
其次,对于二者的具体获取方式,说明如下。
在一些实施例中,第一换电时间T1和第一换电量C1可以是用户在车联联网设备的触控屏或者用户在手机等移动终端设备上的预约换电应用程序(application,APP)或者预约换电网页等信息输入模块上输入的。在一个具体的示例中,用户可以自行选择是否输入第一换电量C1,当接收到用户输入的第一换电量C1时,默认用户选择更换目标电量的电池,其中目标电量可以是100%SOC,或者90%SOC等预设值,其可以根据具体场景和实际需求设置,对此不再赘述。
在另一些实施例中,第一换电时间T1可以是计算得到的。
在一个示例中,第一换电时间T1的具体计算方式包括:

步骤A2,根据用户的位置信息、换电站的位置信息以及驾驶习惯信息,计算第一换电时刻。
示例性地,可以根据用户在一段时间周期内的驾驶速度计算平均驾驶速度V,以及根据用户的位置信息和换电站的位置信息计算车辆与换电站之间的距离S。根据距离S与平均驾驶速度V,计算第一换电时间T1。比如,可以将距离S与平均驾驶速度V的比值Ta作为第一换电时间T1,或者将比值Ta与车辆触发预约换电操作的时间的和值作为第一换电时间T1。又比如,根据用户的刹车频率以及比值Ta,计算用户的刹车次数N,将刹车平均时长与N的乘积Tb与比值Ta的和值作为第一换电时间T1,或者将刹车平均时长与N的乘积Tb、比值Ta以及车辆触发预约换电操作的时间的和值作为第一换电时间T1。
在一些实施例,当车辆所安装电池的数量为多个时,换电请求还可以包括电池数量,比如,若车辆中1个或者多个电池故障,则可以接收用户通过上述信息输入装置输入的电池数量。又比如,可以根据车辆的车型信息,确定车辆对应的电池数量。比如,A车型对应2个电池,B车辆对应3个电池,则接收到A车型车辆的车型信息之后,可以确定需要更换2个电池包。又比如,若用户没有输入,则默认电池数量为预设数量。比如,可以是2或者3等车辆常设置的电池位数量,预设数量可以根据实际 场景和具体需求设置,对此不再赘述。
需要说明的是,当车辆安装M个电池,且电池需要同时更换时,换电请求还可以不包括电池数量。换电装置接收到换电请求之后,会确定需要M个电池。其中,M为大于或等于2的整数。
S420,在将第一充电参数调整为第二充电参数对换电站的可用电池充电的情况下,基于第一换电时间和第一换电量确定第二换电时间和第二换电量。
首先,对于换电站。在一些实施例中,其可以是车辆用户选择的目标换电站。比如,可以是用户在上述信息输入装置上从多个可选换电站中选择的目标换电站。又比如,可以是在车辆所抵达的换电站。在另一些实施例中,换电站可以是具备提供换电能力的多个换电站。比如,若换电方法的执行主体为云端服务器,换电请求包括车辆的剩余电量信息,则可以是云端服务器接收到车辆的换电请求之后,基于所述剩余电量信息,确定所述车辆的剩余行驶里程确定以换电信息所对应的车辆位置为中心、以该剩余行驶里程为半径的预设范围内的多个换电站,然后对多个换电站,执行S420。
需要说明的是,换电站的其他内容可参见本申请上述部分的相关内容,在此不再赘述。
其次,对于可用电池。在本申请实施例中可用电池可以表示可以被换上车辆的电池。其中,可用电池可以是换电站以第二充电参数充电时,电量在第二换电时间达到第二换电量的电池。在一些实施例中,若换电站内在第二换电时间达到第二换电量的电池的数量P大于用户所需电池的数量M,则从P个电池中选出的M个电池作为可用电池。
在一些实施例中,可用电池还需要是电池温度处于预设温度范围内的电池。其中,预设温度范围可以是适宜电池工作的温度区间。当电池的温度处于该预设温度范围内时,电池可以具有良好的充放电性能以及安全稳定性。在一些实施例中,预设温度范围可以是电池的正常工作温度区间,示例性地,预设温度范围可以是(+10℃,+∞)。在一个可选的实施例中,预设温度范围可以是(+20℃,+55℃)。
示例性地,若换电站中在第二换电时间达到第二换电量的总数大于或等于车辆所需要更换的电池数量M,但是温度处于预设温度范围内的电池的数量小于M,则可以对部分温度处于该预设温度范围之外的电池进行温度调制,以使换电站能够在第二换电时间提供电量等于第二换电量、且温度处于预设温度范围的M个可用电池。
具体地,对于温度高于该预设温度范围的上限温度值的电池,可以利用散热模块对其进行散热。其中,散热模块可以是半导体散热片、散热管路等散热模块,对此不作限定。
以及,对于温度低于该预设温度范围的下限温度值的电池,可以以电池自加热模式、以环境温度对电池进行加热模块或者加热模块进行加热的模式对其加热。
在另一些实施例中,若车辆需要电池的数量为M个,则M个电池还需要满足预设成组条件,其中,预设成组条件可以包括下述子条件A-C中的至少一者。
子条件A:可用电池彼此间的电压差值小于预设压差阈值。在一个示例中,预设压差阈值可以根据电池中电池单体的最大允许采样误差值ΔV以及单个可用电池内的电池单体的数量L确定的。比如说,预设压差阈值可以为ΔV×L。比如,最大允许采样误差值ΔV可以是0.48伏特(V)。需要说明的是,预设压差阈值可以根据实际场景和具体需求采用不同设置方式或者取值,比如具体数值可以是2V,对其设置方式和具体取值不作限定。
通过设置子条件A,可以防止因可用电池之间压差过大烧坏电池供电线路上的继电器的风险,提高了电池的安全性以及可靠性。以及,可以防止因可用电池之间的压差在可用电池之间产生的环流对电池电量的消耗,降低了电池的耗电速度。
子条件B:可用电池彼此间的电量参数的差值小于预设电量差阈值。其中,电池参数可以是能够衡量电池容量的参数,比如可以是电池的电量,或者说是电池的SOC,对此不作限定。另外,预设电量差阈值可以根据实际场景和具体需求设置,比如,以电量参数为SOC为例,预设电量差阈值的取值可以是3%或者5%,对其设置方式和具体取值不作限定。
在一些实施例中,由于当电池使用寿命相差较大时,会导致相同电压的电池的SOC存在差异。当M个电池同时满足上述子条件A和子条件B时,可以保证电池的充放电特性的一致性,从而避免因使用过程因电池使用寿命差值不一致所造成的额外电量损耗以及安全风险。
子条件C:可用电池彼此间的电池健康程度(State Of Health,SOH)的差值小于预设SOH差值阈值。
对于SOH,其表示电池老化程度。其中,SOH越小,则电池老化程度越高。比如,SOH=100%表示电池处于出厂之前或者出厂时,即电池处于初始寿命时期(Beginning of Life,BOL)的电池老化程度。SOH=0%则表示电池处于报废状态。在一个具体的示例中,电池在目标时刻下的SOH可以用电池在目标时刻下的满充容量与额定容量的比值来表示。在另一个具体的示例中,电池在目标时刻下的SOH可以用电池在目标时刻下的剩余循环次数与电池的总循环次数的比值。需要说明的是,SOH还可以是其他表示方式,比如最大放电容量和内阻等,本申请实施例对此不作具体限定。
对于预设SOH差值阈值,其可以根据实际场景和具体需求设置,对其设置方式和具体取值不作限定。
由于电池的健康程度差异会在电池的使用过程中造成充放电性能差异,通过子条件C可以保证电池的充放电特性的一致性,从而避免因使用过程因电池使用寿命差值不一致所造成的额外电量损耗以及安全风险。
子条件D:可用电池彼此间的温度差值小于预设温差阈值。
在一些实施例中,预设温差阈值可以根据实际场景和具体需求设置,比如其具体取值可以是3摄氏度(℃),对其设置方式和具体取值不作限定。
通过子条件D,通过调整温度,可以保证各电池包的充放电性能处于较优状态。
在一些实施例中,若换电站内在满足上述预设成组条件、且能够在第二换电时间以第二充电参数充至第二换电量的可选电池数量P大于用户所需电池的数量M,除了上述子条件之外,还可以按照下述子条件从P个可选电池中选择M个可用电池。
子条件E:在P个可选电池中选择进入换电站的时间最早的M个电池匹配成组。通过子条件E,可以防止电池在换电站内被闲置,均衡各电池的使用频率,从而在整体上保证了电池寿命的均衡性。
子条件F,若换电站内分别有多组可选电池组,其中每个可选电池组中的电池彼此之间均满足上述预设成组条件,则可以选取对应的换电量最高的一组可选电池组的电池作为可用电池。
在数量上,本申请实施例为车辆提供的可用电池的数量可以与车辆上的最大可安装电池的数量相同,也就是说,可以用可用电池替换下车辆上的所有电池。又或者,可以为车辆提供的可用电池的数量小于车辆上的最大可安装电池的数量,也就是说,可以用可用电池替换下车辆上的部分电池。对可用电池的数量不作具体限定。
需要说明的是,若用可用电池替换下车辆上的部分电池,则可用电池在第二换电时间数需要与车辆上剩余电池在第二换电时间满足上述预设成组条件。
在充分说明了可用电池之后,接下来对充电参数展开具体说明。
对于第一充电参数以及第二充电参数,第一充电参数和第二充电参数可以是与电池充电速率相关的参数。其中,第二充电参数对应的充电速率大于第一充电参数对应的充电速率。
在一个示例中,第一充电参数可以为第一充电倍率,第二充电参数可以为第二充电倍率。其中,第一充电倍率小于第二充电倍率。
在另一个示例中,第一充电参数可以为第一电流值,第二充电参数可以为第二电流值。其中,第一电流值小于第二电流值。
在又一个示例中,第一充电参数可以为第一电压值,第二充电参数可以为第二电压值。其中,第一电压值小于第二电压值。
在本实施例中,换电站可以以第一充电参数对电池充电,以尽量减缓电池老化,延长电池寿命。换电站也可以以第二充电参数对电池充电,来提高充电效率。在本实施例中,可以响应于换电请求,根据第二充电参数估算第二换电时间以及第二换电量,提高了估算准确度,从而能够根据换电站的潜在换电能力来估算第二换电时间以及第二换电量,进而可以提高换电站的换电能力。
在介绍完充电倍率之后,接下来,将结合换电站的充电能力,分为多个实施例对S420中第二换电时间和第二换电量展开具体说明。
首先,第二换电时间为换电站提供的推荐换电时间,第二换电量为换电站提供的推荐换电量。第二换电量可以是换电站以第二充电参数对可用电池充电的情况下,可用电池在第二换电时间的预估电量。
在一些实施例中,为了提高电池性能参数的采样准确度,第二换电时间包括可用电池的静置时间和基于第二充电参数对换电站的可用电池充电的充电时间。其中,静置时间可以根据实际场景和具体需求设置,比如10分钟等,对此不作具体限定。
通过本实施例,由于电池在静置一段时间之后,电池性能参数采集准确度较高,从而使得制备出的可用电池的真实性能参数符合车辆需求。
接下来,本申请实施例将结合换电站的充电能力对第二换电时间和第二换电量展开具体说明。
在一些实施例中,在换电站以第二充电参数对换电站的可用电池充电的情况下,若可用电池在第一换电时间可达到第一换电量,则第二换电时间与第一换电时间相同,且第二换电量与第一换电量相同。也就是说,如果换电站具备在预约充电时间充电至预约换电量的能力,则向车辆推荐在第一换电时间来更换上第一换电量的可用电池。比如,换电站以第二充电参数对换电站的可用电池充电,若可用电池在时间tx达到第一换电量,则时间tx小于或等于第一换电时间T1,则表示可用电池在第一换电时间可达到第一换电量。
在另一些实施例中,在换电站以第二充电参数对换电站的可用电池充电的情况下,若可用电池在第一换电时间可达到第二换电量且小于第一换电量,则第二换电时间与第一换电时间相同。也就是说,若换电站在用户的预约换电时间无法调制出车辆的预约换电量,则可以向车辆推荐在第一换电时间来更换上第二换电量的可用电池。
在又一些实施例中,在换电站以第二充电参数对换电站的可用电池充电的情况下,若可用电池在第二换电时间可达到第一换电量,则第二换电时间长于第一换电时间,第二换电量等于第一换电量。也就是说,若换电站在用户的预约换电时间无法调制出车辆的预约换电量,则可以向车辆推荐在第二换电时间来更换上第一换电量的可用电池。
S430,向车辆的终端设备发送换电响应。
在S430中,换电响应包括第二换电时间和第二换电量。
在一些实施例中,为了能够提高换电灵活性,换电响应还可以包括除了第二换电时间T2和第二换电量C2之外的其他换电时间,以及与其他换电时间对应的第二换电量。比如,换电响应包括:第二换电时间T2以及在第二换电时间T2的推荐换电量,以及第三换电时间T3以及第三换电时间T3的推荐换电量等。
示例性地,在换电站以第二充电参数对可用电池充电的情况下,在第二换电时间可用电池的电量等于第一换电量,第二换电时间大于第一换电时间,也就是说,换电站以第二充电参数充电时无法在用户预约换电时间为用户提供预约换电量。则换电响应还可以包括第一换电时间以及换电站以第二充电参数对电池充电时可用电池在第一换电时间的换电量。比如,车辆预约在15:00更换95%SOC的电池,但是换电站以第二充电参数在15:00时能充好75%SOC的电池,以第二充电参数在15:30能充好95%的电池。则换电响应可以包括:第二换电时间15:00、第二换电量95%,以及第三换电时间15:00、第三换电量75%,以供车辆从中选择合适的换电时间以及合适的换电量。
在另一些实施例中,为了给车辆提高更加灵活的换电策略,换电响应还可以包括换电站以第一充电参数对可用电池充电时,换电站在第四换电时间的推荐换电量。比如,换电站以第一充电参数对可用电池充电时在第一换电时间的换电量,以及换电站以第一充电参数对可用电池充电时在第四换电时间达到第一换电量时,换电响应还可以包括第四换电时间和第四换电量,其中,第四换电量的数值等于第一换电量。
本申请实施例的换电方法,在接收到车辆的换电请求之后,可以在将第一充电参数调整为第二调整参数的情况下,根据车辆的换电请求中的预约换电时间以及预约换电量为车辆提供推荐换电时间以及推荐换电量。从而使得车辆可以在预约换电时,根据换电站的充电能力为车辆的终端设备提供推荐换电时间以及推荐换电量,以使用户可以根据推荐换电时间以及推荐换电量确定是否换电,提高了用户的使用体验。
在一些实施例中,若接收到车辆的终端设备的换电确认信息,则可以控制换电站制备可用电池。
针对具体制备方式,本申请实施例具体说明如下。
在一种示例中,若可用电池的电量为第一换电量,也就是说,在车辆预约时已经有充好的可用电池,则可以静置存放可用电池,直到车辆达到时为车辆更换。
在另一种示例中,若以第一充电参数对可用电池充电时,可以在第一换电时间达到第一换电量,则可以以第一充电参数对可用电池充电。
通过本实施例,由于以第一充电参数为可用电池充电能够延长电池使用寿命,因此在该情况下选用第一充电参数为可用电池充电能够保证换电站为车辆定时的提供指定换电量的情况下提高了电池使用寿命。
需要说明的是,在该情况下,若换电站的充电位置不足,比如多个车辆所预约的电池数量大于换电站的充电仓数量,为了整体提高充电流程,可以以第二充电参数对可用电池充电。
在又一种示例中,若以第一充电参数对可用电池充电时在第一换电时间的换电量小于第一换电量,且以第二充电参数对可用电池充电时在第一换电时间的换电量大于第一换电量。
为了保证充电质量,可以先以第二充电参数充电,在达到预设电压值或者预设时间之后,再调制为第二充电参数为电池充电。
在再一种示例中,若电池在第二充电参数对可用电池充电时,在第二换电时间的换电量等于第一换电量,第二换电时间大于第一换电时间时,也就是说,换电站以大速率(第二充电参数)充电时,换电站在车辆预约换电时间无法调制出预约换电量,则可以控制换电站以第二充电速率充电,直到达到第一换电量。
通过上述多个示例充分介绍了换电站的充电调制策略之后,由于在一些实施例中,接下来对可用电池与车辆的绑定关系进行具体说明。
在一些实施例中,为了保证换电过程的可靠性,在接收到车辆的终端设备的换电确认信息之后,可以建立车辆与可用电池的绑定关系。
通过本实施例,可以在接收到车辆的换电请求之后,为车辆预留可用电池,能够避免车辆到达换电站之后才发现电池被其他车辆换走等情况的发生,提高了换电流程的可靠性,提高了用户的换电体验。
在结合图4和上述实施例充分介绍了本申请实施例提供的第一种换电方法之后,基于相同的发明构思,本申请实施例还提供了第二种换电方法。第二种换电方法包括下述步骤B1至B3。
步骤B1,接收车辆的换电请求。换电请求包括第一换电时间,第一换电时间为预约换电时间。
步骤B2,在将第一充电参数调整为第二充电参数对换电站的可用电池充电的情况下确定换电站在第一换电时间的预估换电量。
步骤B3,向车辆的终端设备发送换电响应,换电响应包括第一换电时间和预估换电量。
在一些实施例中,为了提高换电策略的灵活性,换电响应可以包括多个充电参数对应在第一换电时间的预估换电量。其中,每一充电参数在第一换电时间的预估换电量包括换电站以该充电参数对可用电池充电时,可用电池在第一换电时间可达到的换电量的预估值。
需要说明的是,第二种换电方法的其他内容与上述第一种换电方法的内容相似,在此不再赘述。
与上述第一种换电方法的不同之处在于,上述第一种换电方法可以为车辆以及换电站之间提供一种可协商的换电模式,第二种换电方法提供了一种以换电站的换电能力为主的换电模式。
此外,基于相同的发明构思,本申请实施例还提供了第三种换电方法。第三种换电方法包括下述步骤C1至C3。
步骤C1,接收车辆的换电请求。换电请求包括第一换电量,第一换电量为预约换电量。
步骤C2,在将第一充电参数调整为第二充电参数对换电站的可用电池充电的情况下确定可用电池的电量达到第一换电量的预估充电完成时间。
在一个示例中,为了降低电池电量的采集误差,预估充电完成时间包括可用电池达到第一换电量之后的静置时间。
步骤C3,向车辆的终端设备发送换电响应,换电响应包括第一换电量和预估充电完成时间。
在一些实施例中,为了提高换电策略的灵活性,换电响应可以包括以多个充电参数对可用电池充电时第一换电量的预估充电完成时间。
与上述两种换电方法的不同之处在于,第三种换电方法提供了一种以用户换电要求为主的换电模式。
基于相同的申请构思,本申请实施例除了提供了换电方法之外,还提供了与之对应的换电装置。
