随着可移动平台进入的行业越多(比如农业,电力以及很多特殊场景应用),可移动平台的使用也越频繁。以无人机为例,无人机采用电池供电,电池输出的电能作为无人机的飞控供电和动力来源。当无人机的电池电量耗尽时,需要及时为电池充电来保障无人机的继续使用。
如果无人机的电池的温度较低,则对无人机的电池加热,直至电池的温度不小于预设值时停止加热,然后开始对电池充电,在这个温度下对电池充电能保证电池的充电效率。发明人发现,如果过一段时间后电池的温度又下降至小于预设值,则停止对电池的充电,并再次对无人机的电池加热,直至电池的温度不小于预设值停止加热,然后再次对电池充电。循环多次这样的操作,直至电池充电结束。但是,从电池开始充电到充电结束,电池并未处于恒温过程,如此充电过程会影响电池的使用寿命。
基于此,本申请的实施例提供了电池加热方法、充电装置、系统、电池和可移动平台。在采用充电装置对电池的充电过程中,通过控制对加热装置的供电,采用加热装置对电池进行加热,使得电池基本处于恒定的温度下进 行充电,以抵消低温的外部环境所造成的热量损失。

当无人机的电池电量不足时,需要采用充电装置对电池进行充电以提高电池的电量,然后再次为无人机提供充足的动力,保证无人机的正常工作。其中,无人机基本上在室外环境下工作,而且大部分情况下是在野外大自然环境下工作,所以很在可能在野外大自然环境工作的过程中电量不足,需要在当前环境下及时对电池进行充电以保证无人机能继续工作。当野外大自然环境的环境温度低时,要保证电池的充电性能,在充电前对电池进行加热,提高电池的自身温度至预设充电温度,然后再开始对电池充电。但是,电池当前处于低温的野外大自然环境下,这种自然环境下的温度又无法改变,而且低温的环境会使得加热过的电池的热量散失,从而使得电池的自身温度下降,影响电池的充电性能。因此,针对这种在电池外部环境的温度无法改变的情况下,为了保证电池的充电性能,可以在电池在充电过程中使得电池的自身温度基本上处于恒定状态,以避免电池的自身温度下降至预设充电温度。因此,本申请提出了一种在采用充电装置对电池的充电过程中,采用加热装置对电池进行间歇加热以抵消低温的外部环境所造成的热量损失的方案。其中,本申请中的充电装置可以是充电器或者充电箱等。
本申请提及的加热装置可以设置于充电装置中。如图2所示,充电箱200中设置有电池仓201,电池仓201用于容纳电池202,当电池202需要充电时,可以将电池202放入电池仓201内,充电箱200可以对电池202进行充电。另外,充电箱200中还设置有加热装置,加热装置可以对电池仓201内的电池202进行加热。
或者,本申请提及的加热装置可以设置于电池中。如图3所示,电池内设置有加热装置301,而且加热装置301形成有多个电芯仓位,电池的电芯组中的各个电芯302容纳于电芯仓位内,从而加热装置301可以对各个电芯行加热。在一种实现方式中,加热装置301可以为加热膜。
其中,图3中以每个电芯仓位内容纳有一个电芯为例示出,电芯的上下两个表面均与加热装置接触。在另一种实现方案中,图4所示,加热装置301形成多个电芯仓位,每个电芯仓位内容纳有2个电芯,一个电芯的上侧面与加热装置接触,另一个电芯的下侧面与加热装置接触。
下面采用几个具体的实施例对本申请的方案进行详细介绍。
图5为本申请一实施例提供的电池加热方法的流程图,如图5所示,本实施例的方法可以应用于充电装置,也可以应用于电池。本实施例的方法可以包括:
S501、在充电装置对电池充电的过程中,获取第一占空比,所述第一占空比与所述电池所处环境的环境温度有关。
本实施例中在充电装置对电池充电的过程中,获取用于表示控制加热装置对电池进行间歇加热的占空比,该占空比称为第一占空比。并且第一占空比与电池所处环境的环境温度有关。电池所处环境的环境温度不同,相应的第一占空比也可能不同。比如第一占空比为0.5,则可以表示每一秒钟中存在0.5秒的时长加热装置对电池进行加热,而另外0.5秒加热装置不对电池进行加热。
可以理解,在充电装置对电池充电的过程中,可以是获取第一控制信号,第一控制信号包括第一占空比。该第一控制信号还可能包括其他信息,例如,为电池充电的电压和/或电流,从而在为电池加热的同时,为电池充电。
S502、根据所述第一占空比,控制所述加热装置对所述电池进行间歇加热。
本实施例中,在获取到第一占空比后,根据该第一占空比,在充电装置对电池充电的过程中,控制加热装置对电池进行间歇加热,以使电池在充电过程中的电池的自身温度基本恒定。
本实施例的方法可以应用于充电装置,如果加热装置设置于电池,则充电装置控制电池的加热装置对电池进行间歇加热。如果加热装置设置于充电装置,则充电装置控制充电装置的加热装置对电池进行间歇加热。
本实施例的方法可以应用于电池,如果加热装置设置于电池,则电池控制电池的加热装置对电池进行间歇加热。如果加热装置设置于充电装置,则电池控制充电装置的加热装置对电池进行间歇加热。
本实施例中,通过在充电装置对电池充电的过程中,获取第一占空比,所述第一占空比与所述电池所处环境的环境温度有关;并根据所述第一占空比,控制所述加热装置对所述电池进行间歇加热。通过在充电装置对电池充电过程中对电池间歇加热,来弥补因为电池所处的低温环境造成电池自身热 量的损失,以保证电池的自身温度在充电过程保持基本恒定,不会因为电池的自身温度而中断电池的充电过程,保证电池处于持续充电的状态,提高电池的充电效率,提高电池的使用寿命。
在一些实施例中,上述第一占空比越大,加热装置对电池间歇加热的过程中持续加热的时长越长。以一个间歇加热时长1秒为例,比如第一占空比为0.5,表示每一秒时间内持续加热的时长为0.5秒,另外0.5秒加热装置停止对电池加热;比如第一占空比为0.2,表示每一秒时间内持续加热的时长为0.2秒,另外0.8秒加热装置停止对电池加热。这也表示第一占空比越大,在充电过程中电池获得的热量越多。
在一些实施例中,第一占空比与环境温度负相关。电池所处环境的环境温度越低,环境会造成电池的热量损失越多,所以第一占空比越大,这样电池通过加热装置可以获得的热量越多,尽可能与损失的热量持平,以保证电池的自身温度恒定。
在图5所示实施例的基础上,图6为本申请另一实施例提供的电池加热方法的流程图,如图6所示,本实施例的方法可以应用于充电装置,也可以应用于电池,本实施例的方法可以包括:
S601、在充电装置对电池充电的过程中,获取所述电池所处环境的环境温度。
本实施例中,在充电装置对电池充电的过程中,获取电池所处环境的环境温度。
其中,电池内可以设置有温度检测装置,该温度检测装置可以检测电池的自身温度。
其中,充电装置内可以设置有温度检测装置,该温度检测装置可以检测充电装置的自身温度。
若本实施例的方法应用于充电设备,上述S601可以存在如下两种实现方式:
在第一种可能的实现方式中,获取充电装置与电池建立连接时从电池获取的电池的自身温度为环境温度。其中,充电装置与电池建立连接时,充电装置与电池之间可以相互通信,电池可以获取电池的温度检测装置检测到的电池的自身温度,并将电池的自身温度通过电池与充电装置之间的通信信号 发送给充电装置。由于充电装置与电池建立连接时,充电装置还未开始对电池充电,电池的自身温度还未受到充电过程中产生热量的影响,而且加热装置也未开始对电加热,电池的自身温度还未受到加热装置产生热量的影响,所以此时电池的自身温度与电池所处环境的环境温度接近,因此,充电装置可以将充电装置与电池建立连接时电池的自身温度确定为环境温度。
在第二种可能的实现方式中,充电装置的温度检测装置可以检测充电装置的自身温度,由于充电装置与电池处于相同环境中,所以充电装置可以将温度检测装置检测到的充电装置的自身温度确定为电池所处环境的环境温度。可选的,为了避免充电装置对电池充电过程中产生的热量的影响,本实施例可以将充电装置与电池建立连接时充电装置的温度检测装置检测的充电装置的自身温度确定为环境温度。
若本实施例的方法应用于电池,上述S601可以存在如下两种实现方式:
第一种可能的实现方式中,获取充电装置与电池建立连接时电池的温度检测装置检测到电池的自身温度。由于充电装置与电池建立连接时,充电装置还未开始对电池充电,电池的自身温度还未受到充电过程中产生热量的影响,而且加热装置也未开始对电加热,电池的自身温度还未受到加热装置产生热量的影响,所以此时电池的自身温度与电池所处环境的环境温度接近,因此,电池可以将充电装置与电池建立连接时电池的自身温度确定为环境温度。
在第二种可能的实现方式中,充电装置的温度检测装置可以检测充电装置的自身温度,充电装置可以将温度检测装置检测到的充电装置的自身温度发送给电池。由于充电装置与电池处于相同环境中,所以电池可以将充电装置的自身温度确定为电池所处环境的环境温度。可选的,为了避免充电装置对电池充电过程中产生的热量的影响,本实施例可以将充电装置与电池建立连接时从充电装置获取的充电装置的自身温度确定为环境温度。
S602、根据所述环境温度,确定第一占空比。
本实施例中,在获得电池所处环境的环境温度后,根据该环境温度,确定用于表示控制加热装置对所述电池进行间歇加热的占空比,称为第一占空比。
下面采用几种具体的实现方式对上述S602进行详细介绍。
在一种具体的实现方式中,根据电池的预设充电温度和上述环境温度,确定第一占空比。其中,第一占空比与预设充电温度正相关。预设充电温度越高,为了维持电池的自身温度在充电装置对电池充电的过程中基本恒定在预设充电温度,则需要为电池补偿更多的热量,所以第一占空比越大,使得加热装置间隙加热的过程中持续加热时长越长。从而可以实现电池高温充电,降低电芯的极化,提高电池充电电流,达到快充的目的。
如果本实施例的方法应用于电池,该预设充电温度可以预先存储在电池本地。如果本实施例的方法应用于充电装置,则充电装置与电池建立连接后,电池可以将电池的预设充电温度通过充电装置与电池之间的通信信号发送给充电装置。相应地,充电装置在获取第一占空比前,从电池获取该电池的预设充电温度。
在另一种具体的实现方式中,根据充电装置对电池充电的过程中电池的自身温度和上述环境温度,确定第一占空比。其中,第一占空比与电池的自身温度负相关。在充电装置对电池充电的过程中也会造成电池的自身温度发生变化,如果电池的自身温度越低,为了维持电池的自身温度在充电装置对电池充电的过程中基本恒定,则需要为电池补偿更多的热量,所以第一占空比越大,使得加热装置间隙加热的过程中持续加热时长越长。从而可以实现根据电池的自身温度动态调整第一占空比,使得间歇加热后电池的自身温度基本恒定的基础上,节省能量,避免过加热的情况。
如果本实施例的方法应用于电池,该电池的自身温度可以通过电池的温度检测装置检测得到。如果本实施例的方法应用于充电装置,电池获取在充电装置对电池充电的过程中电池的温度检测装置检测到的该电池的自身温度后,将电池的自身温度发送给充电装置。相应地,充电装置在充电装置对电池充电的过程中,从电池获取该电池的自身温度。
在另一种具体的实现方式中,根据充电装置对电池充电的过程中电池的自身温度、上述环境温度以及电池的预设充电温度,确定第一占空比。既能实现高温充电,也能节省能量,避免过加热的情况发生。
在上述任一实现方式的基础上,可选的,如果环境温度大于等于电池的预设充电温度,则确定的第一占空比例如为0。
S603、根据所述第一占空比,控制加热装置对所述电池进行间歇加热。
如果本实施例的方法应用于充电装置,则充电装置根据第一占空比,控制充电装置与加热装置之间的电连接间歇导通。当充电装置与加热装置电连接导通时,加热装置获得电能,使得加热装置工作,加热装置工作的过程中产生热量,产生的热量用于加热电池。可选的,当所述充电装置与所述加热装置电连接导通时,充电装置控制所述充电装置对所述加热装置输出电流,使得所述加热装置产生热量。其中,充电装置对加热装置输出的电流越大,使得加热装置产生的热量越多;充电装置对加热装置输出的电流越小,使得加热装置产生的热量越少。
如果本实施例的方法应用于电池,则电池根据第一占空比,控制电池的电芯组与加热装置之间的电连接间歇导通。当电芯组与加热装置电连接导通时,加热装置获得电能,使得加热装置工作,加热装置工作的过程中产生热量,产生的热量用于加热电池。可选的,当所述电芯组与所述加热装置电连接导通时,电池控制所述电芯组对所述加热装置输出电流,使得所述加热装置产生热量。其中,电芯组对加热装置输出的电流越大,使得加热装置产生的热量越多;电芯组对加热装置输出的电流越小,使得加热装置产生的热量越少。
需要说明的是,在一些特殊情况下,比如无人机未处于低温环境下,第一占空比为0,则无需控制加热装置对电池进行加热,无需为电池额外增加热量,电池的自身温度也能基本恒定。
另外还需要说明的是,上述的电池的自身温度在充电装置对电池充电的过程中会发生变化,因此第一占空比也会动态变化,所以间歇加热过程也不一定是固定的。
本实施例是根据第一占空比,在充电装置对电池充电过程中对电池间歇加热,来弥补因为电池所处的低温环境造成电池自身热量的损失,以保证电池的自身温度在充电过程保持基本恒定,不会因为电池的自身温度而中断电池的充电过程,保证电池处于持续充电的状态,提高电池的充电效率,提高电池的使用寿命。
在一些实施例中,在执行上述S603之后,还可以执行S604和/或S605。需要说明的是,S604与S605的执行顺序不做限定。
S604、在所述充电装置对所述电池充电的过程中,若所述电池的自身温 度大于预设温度,则控制所述充电装置停止对所述电池充电,和/或,输出提示信息,所述提示信息用于提示所述电池的自身温度大于预设温度。
本实施例中,由于电池内设置有温度检测装置,在充电装置对电池充电的过程中,电池的温度检测装置可以检测到电池的自身温度。
如果本实施例的方法应用于电池,则在充电装置对电池充电的过程中,电池获取电池的温度检测装置检测到的电池的自身温度。然后电池判断电池的自身温度是否大于预设温度,如果电池的自身温度大于预设温度,说明电池的自身温度过高,继续充电会对电池不利,则电池控制充电装置停止对电池充电,比如电池向充电装置发送停止充电指示信息,相应地,充电装置根据从电池获取的停止充电指示信息,停止对电池的充电过程。或者,则电池输出提示信息(比如通过指示灯闪烁,或者,通过蜂鸣器发生蜂鸣声),所述提示信息用于提示所述电池的自身温度大于预设温度,用户获知到该提示信息后可以断开电池与充电装置之间的连接,停止充电装置与电池的充电过程。或者,则电池控制充电装置停止对电池充电以及输出提示信息。如果电池的自身温度小于等于预设温度,则电池继续获取温度检测装置检测到的温度,并判断该温度是否大于预设温度。
如果本实施例的方法应用于充电装置,则在充电装置对电池充电的过程中,电池的温度检测装置检测到的电池的自身温度,电池获取温度检测装置检测到的温度并发送给充电装置。相应地,充电装置从电池获取在充电装置对电池充电的过程中电池的自身温度。如果电池的自身温度大于预设温度,说明电池的自身温度过高,继续充电会对电池不利,则充电装置控制充电装置停止对电池充电,比如充电装置断开与电池的电芯组之间的电连接。或者,则充电装置输出提示信息(比如通过指示灯闪烁,或者,通过蜂鸣器发生蜂鸣声),所述提示信息用于提示所述电池的自身温度大于预设温度,用户获知到该提示信息后可以断开电池与充电装置之间的连接,停止充电装置与电池的充电过程。或者,则充电装置停止对电池充电以及输出提示信息。如果电池的自身温度小于等于预设温度,则充电装置继续从电池获取电池的自身温度,并判断该温度是否大于预设温度。
S605、若所述充电装置对所述电池充电的时长大于等于预设时长,则控制所述加热装置停止对所述电池进行间歇加热。
本实施例中,在充电装置对电池开始充电时,例如通过计时器开始计时,计时的时长即为充电装置对电池充电的时长,然后判断充电装置对电池充电的时长是否小于预设时长,如果充电装置对电池充电的时长大于等于预设时长,说明充电装置对电池充电的时长过长,这么长时间的充电过程应该使得电池的电量已充满,所以没必要再让电池的自身温度基本恒定,然后控制所述加热装置停止对所述电池进行间歇加热,以节省能量。如果充电装置对电池充电的时长小于预设时长,则继续获取充电装置对所述电池充电的时长,并判断该时长是否小于预设时长。
在一些实施例中,在执行上述S601之前,在充电装置对电池充电之前,还可以判断电池的自身温度是否小于预设充电温度,如果电池的自身温度小于预设充电温度,则控制加热装置对电池加热。直至电池的自身温度大于等于预设充电温度时,控制充电装置对电池充电。如果电池的自身温度大于预设充电温度,则控制充电装置对电池充电,需要在充电之前控制加热装置对电池加热。
电池或者充电装置如何获得电池的自身温度可以参见上述实施例中的相关描述,此处不再赘述。
其中,在执行S601之前控制加热装置对电池加热的一种可能的实现方式可以包括S600a和S600b。
S600a、在充电装置对电池充电之前,若电池的自身温度小于预设充电温度,则获取第二占空比。
本实施例中,在充电装置对电池充电之前,并且充电装置与电池建立连接后,若电池的自身温度小于预设充电温度,则获取用于指示控制加热装置对电池加热的占空比,此处的占空比称为第二占空比。
可选的,S600a中获取第二占空比的一种可能的实现方式为,根据充电装置与电池建立连接时电池的自身温度确定第二占空比。其中,第二占空比与电池的自身温度负相关。
可选的,S600a中获取第二占空比的另一种可能的实现方式为,根据充电装置与电池建立连接时电池的自身温度以及预设充电温度确定第二占空比。其中,第二占空比与电池的自身温度负相关,第二占空比与预设充电温度正相关。
可选的,第二占空比可以预先设置的占空比,第二占空比的值为默认值,与电池的自身温度无关。
其中,电池或充电装置如何获取充电装置与电池建立连接时电池的自身温度,可以参见上述实施例中的相关描述,此处不再赘述。
S600b、根据所述第二占空比,控制所述加热装置对所述电池间歇加热,直至电池的自身温度大于等于预设充电温度。
本实施例中,在获得第二占空比后,根据第二占空比,控制加热装置对电池间歇加热,直至电池的自身温度大于等于预设充电温度时,停止根据第二占空比控制加热装置对电池间歇加热。然后控制充电装置对电池进行充电。
可选的,第二占空比大于第一占空比,这样使得充电装置在对电池充电前,电池可以迅速升温。第二占空比例如可以是0.5~1。在一种特殊情况下,第二占空比可以为1。
可以理解,可以获取第二控制信号,该第二控制信号包括第二占空比。该第二控制信号还可包括其他信息,例如用于指示电池在位的信息,因此,能够确保在电池在位的情况下,对电池进行加热。
在一些实施例中,如果本实施例的方法应用于充电装置,充电装置在所述充电装置对所述电池充电的过程,通过对所述电池的在位检测,确定所述充电装置与所述电池是否电连接。如果确定充电装置与电池电连接,则充电装置继续对电池充电,以及在对电池充电的过程中,继续根据第一占空比控制加热装置对电池间歇加热。如果确定充电装置与电池未连接,则充电装置停止对电池充电,以及控制加热装置停止对电池间歇加热,节省能量,避免电能损失。
在一些实施例中,如果本实施例的方法应用于电池,则当所述电池为外部设备供电时,电池还控制所述电芯组对所述加热装置输出电流,使得所述加热装置产生热量。这样保证电池在低温环境下使用时,电池的自身温度不会过低,比如无人机的电池在通过上述方案充电结束后,无人机在低温环境下工作,同样电池也随无人机处理相同的低温环境,通过本方案,电池的自身温度可以保持在预设工作温度基本恒定,保证电池的放电性能。可选的,电池控制电芯组对加热装置输出电流的一种实现方式可以是根据占空比控制电芯组对加热装置输出电流,使得加热装置间歇产生热量。
在一些实施例中,上述的第一占空比可以替换为电流,实现原理类似。比如根据环境温度确定电流,然后根据电流控制加热装置对电池加热。其中,电流越大,加热装置对电池加热产生的执量越多。而且电流的值与环境温度负相关,即环境温度越低,电流的值越大。
