Description

一种充电方法和装置、存储介质 技术领域
本发明涉及电池充电技术,尤其涉及一种充电方法和装置、存储介质。
背景技术
在手机的使用过程中,一些使用场景或者由于用户的使用习惯,会导致手机电池的加速老化。比如,专车或者出租车的司机会长时间,将手机插着充电设备。
二次充电指的是手机等设备在充满电后会截止充电,但由于设备系统自身耗电、电池电压正常回落等因素,导致设备在于充电设备连接的状态下且电池电量降低时,会进行充电的行为。充电超时指的是在规定的时间内可以进行充电,但超过规定时间后会禁止进行充电行为。
由于手机的系统自身耗电、电池电压正常回落等因素,导致连接充电设备的状态下,电池电量降低时,继续进行的充电行为。这样会导致电池长期在满电状态附近进行二次充电,而反复的二次充电对电池的损伤是巨大的,使得电池的使用寿命缩短。
发明内容
本发明实施例的目的在于提供一种充电方法和装置、存储介质,解决了充电电池使用寿命短的问题。
为了达到上述目的,本发明实施例提供一种充电方法,包括:

具体实施方式
为使本发明要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
如图1所示,为本发明实施例提供的一种充电方法的流程示意图,包括以下步骤:
步骤S101、对二次充电门限进行初始化工作,获取一二次充电门限的默认值。
步骤S102、在电子设备与电源适配器连接时,获取一二次充电门限调整参数。
步骤S103、根据所述二次充电门限调整参数判断是否需要调整所述二次充电门限,得到一判断结果。
步骤S104、当所述判断结果指示需要调整所述二次充电门限时,将所述二次充电门限从所述默认值调整为小于所述默认值的当前值。
步骤S105、利用所述当前值进行二次充电控制。
在本实施例中,获取二次充电门限调整参数,其中二次充电门限调整参数可以为各种参数,并根据二次充电门限调整参数判断是否需要进行二次充电,在需要进行二次充电的情况下,将二次充电门限调整为小于初始默认值的当前值,通过调整二次充电门限值对电池进行二次充电控制,减少二次充电次数,从而最大程度上减少电池长期在满电状态附近进行的二次充电行为。这样可以最大程度上的降低对电池的损耗,延长电池的使用寿命和提升电池的使用效率。
本发明实施例中,需要根据二次充电门限调整参数来判断是否减小二次充电门限。二次充电门限参数可以是各种参数,以下分别说明如下。
<二次充电门限调整参数为工作模式参数>
这种方式下,所述二次充电门限调整参数为工作模式参数,所述根据二次充电门限调整参数判断是否需要调整二次充电门限的步骤中,当所述工作模式参数表示所述电子设备工作于车载模式时,得到指示需要调整二次充电门限的判断结果。
如图2所示,为本发明实施例提供的一种在车载模式下调整二次充电门限的流程示意图,包括以下步骤:
步骤S201、手机进入车载模式。
步骤S202、车载模式相关的进程开启的时候,监听进程会查询到,并在充电模块进行相应操作。当手机检测到处于充电状态且处于车载模式的情况下,会检查用户是否有配置二次充电门限和充电超时门限。
步骤S203、当用户没有配置二次充电门限的时候,将二次充电门限调整至当前值。
在本实施例中,假定电池容量为3000mAh,导航模式下耗电电流为300mA,用户一上午或下午从满电开始使用导航模式(时间约为4小时),那么4小时耗电为1200mAh,所述当前值可以设置为70%。
步骤S204、当用户配置了二次充电门限的时候,执行用户配置。
在本实施例中用户配置第二次充电门限为70%,即当电量低于70%的时候,进行二次充电。
很多司机会有将手机一直插着充电设备的习惯,或者由于运行打车软件等工作的需要,在车载模式下,手机一直处于较大的负载状态,所以会频繁的进行二次充电,这对于电池的损伤是非常严重的。在实际使用过程,对二次充电门限进行调整,将充电行为维持在一个可控的范围内,避免电池的长时间处于二次充电状态,减少电池的二次充电次数,从而最大程度上的降低对电池的损耗,延长电池的使用寿命和提升电池的使用效率。
对此举例说明如下。
假定电池容量为3000mAh,导航模式下耗电电流为300mA(即每半小时耗费5%的电量),初始的二次充电门限为95%,而本发明实施例的当前值设置为70%。
假定出租车司机从下午1点持续工作到晚上7点,从满电开始使用导航模式。根据相关技术提供的充电方案,每半小时就需要进行一次充电,6小时需要充电12次。而利用本发明实施例的方法,每3小时充电一次,6小时只需要充电2次,充电次数只有相关技术的1/6。当当前值设置的更小时,则充电次数更好。
但为了保证用户任何时候离开车辆手机都具有一定的电量可以使用,该当前值一般不低于60%。
<二次充电门限调整参数为电池老化系数>
这种方式下,所述二次充电门限调整参数为电池老化系数,所述根据二次充电门限调整参数判断是否需要调整二次充电门限的步骤中,当所述电池老化系数小于第一预定门限时,得到指示需要调整二次充电门限的判断结果。
所述将所述二次充电门限从所述默认值调整为小于所述默认值的当前值的步骤中,所述电池老化系数越小,所述当前值越低。
如图3所示,本发明实施例提供的一种在电池老化的情况下调整二次充电门限的流程示意图,包括以下步骤:
步骤S301、检查电池老化状态,获取电池老化系数。老化状态的检查是通过电池的充放电次数、完整充放电过程的库伦即数据以及在高温状态下的运行时间等计算出来的。
步骤S302、基于S301,当手机检测到电池处于老化的时候,会进一步检查用户是否有配置二次充电门限和充电超时门限。
步骤S303、当用户没有配置二次充电门限时候,将所述二次充电门限从所述默认值调整为小于所述默认值的当前值,所述当前值按照下面的分段函数配置二次充电门限。
步骤S304、当用户配置了二次充电门限的时候,执行用户配置。
随着电池充放电次数的增加和使用时间,手机电池的老化程度会加深。根据老化程度的不同,设置不同的二次充电门限,用以下分段函数表示:
Figure PCTCN2016102620-appb-000001
其中上面分段函数中的门限值,用户可以根据实际情况自行调整。
其中老化系数是指目前可用最大容量与额定容量的比值。老化系数为0.8,说明手机的可用最大容量已经下降为出厂时候可用容量的80%。手机在使用的过程中,老化一直在发生,所以这个门限在本实施例中设置的数值,在老化系数是0.6以上呈线性关系。在实际应用中,对于老化系数在0.6以下的电池,老化程度已经非常严重,基本处于淘汰状态。在本实施例中门限设置为60%,设置在60%上下,可以保证用户保持有一定的用电量, 同时也能在一定程度上减少电池的二次充电次数,从而延长电池的使用寿命。
<二次充电门限调整参数为持续充电时间>
这种方式下,所述二次充电门限调整参数为持续充电时间,所述根据二次充电门限调整参数判断是否需要调整二次充电门限,当所述持续充电时间大于第二预定门限时,得到指示需要调整二次充电门限的判断结果。
所述将所述二次充电门限从所述默认值调整为小于所述默认值的当前值的步骤中,所述持续充电时间越长,所述当前值越低,二者的负相关的数量关系可以使用下降趋势的一次函数或多次函数表示。
如图4所示,本发明实施例提供的一种在长时间充电情况下调整二次充电门限的流程示意图,包括以下步骤:
步骤S401、当充电的时候,获取目前充电时间。当充电设备连接的时候,会触发充电相关的中断,同时拔出的时候,也会触发充电相关的中断。依据于此,可以获取连接充电设备的时间。
步骤S402、基于S401,检查用户是否配置二次充电门限和充电超时门限。
步骤S403、当用户没有设置二次充电门限时候,将所述二次充电门限从所述默认值调整为小于所述默认值的当前值,所述当前值按照下面的分段函数配置二次充电门限。
步骤S404、当用户配置了二次充电门限的时候,执行用户配置。
在本实施例中用户配置的二次充电门限为80%,即当电量低于80%的时候,进行二次充电。
手机在实际使用过程中,用户经常会遇到长时间充电的场景,如过夜充电等,根据充电时间的不同,设置不同的二次充电门限,有以下分段函数表示:
Figure PCTCN2016102620-appb-000002
其中上面分段函数中的门限值,用户可以根据实际情况自行调整。
其中,充电时间指的是连续插入充电设备的时间,市面上绝大部分手机的充电时间会小于4个小时,在用户轻度使用的时候,充电时间会相应增加一些。而过夜充电等此类情况充电时间一般都会超过6个小时,在这种情况下,将门限设置为95%,基本能保证待机充电期间不会出现和很少出现二次充电动作。在本实施例中,比如在手机充电的过程中,用户因为出差或者旅行而忘记插拔,让手机长时间处于充电状态,在这种情况下,二次充电门限需要大幅降低,以减少用户因为外出或者出差期间手机的二次充电次数。减少电池二次充电的次数,来降低持续二次充电对电池的损耗,从而延长电池的使用寿命和提升电池的使用效率。
如图5所示,本发明实施例提供的一种在不同充电场景下调整二次充电门限的流程示意图,包括以下步骤:
步骤S501、系统开启的时候,进行二次充电门限的初始化工作。
步骤S502、基于步骤S501,检测到特殊模式后,调整二次充电的门限值。
步骤S503、基于步骤S501,根据电池的老化情况,调整二次充电的门限值,老化程度越严重,二次充电门限值越低。当严重到一定程度的时候,禁止二次充电。
步骤S504、基于步骤S501,当检测到系统长时间充电的时候,调整二次充电门限值。如果有设置充电超时门限值,在超时后,禁止二次充电。
步骤S505、基于步骤S501,用户可以基于系统的友好提示,根据自己的实际情况和偏好,自定义二次充电门限值和充电超时门限值,设定后会 一直保存到手机设置的数据里,系统重启或者再次启动后会首先加载用户配置的数据,再根据该数据在进行动态调整。如果用户自定义了二次充电门限值,S102-S104不会再起作用。系统不会允许用户自定义比默认值更高的门限值。如果用户配置了充电超时时间,当充电时间达到该值的时候,系统会禁止充电,直到再次触发充电流程。在此实施方案中,用户可以根据自身的需求进行自由设置和选择,因此进一步满足了用户的个性化需求,提高了用户的体验度。
步骤S506、基于步骤S501,当退出二次充电状态时候,同样会清除二次充电的动态调整,恢复配置到默认状态。
需要注意的是,在诸多动态调整的因素里,在初始化后,首先会根据用户是否进行了二次充电门限值的配置,在进行后面的S502-S504的动态调整,且会在S502-S504出现交集的情况下,会取最小值,即最严格的二次门限值。
