S101、在检测到对所述终端进行充电的条件满足时,获取所述终端的当前状态信息;其中,所述当前状态信息至少包括以下之一:电池温度、电池电量、用户设置的充电参数;
一般来说,如果检测到所述终端与电源适配器建立电性连接时,确定对所述终端进行充电的条件满足,此时,可以按照预设的时间间隔获取所述终端的当前状态信息,或者,检测到所述当前状态信息中的任一状态满足预设条件时,获取所述终端的当前状态信息,例如,所述电池温度在单位时间内的变化值大于预设的温度阈值时,获取所述终端的当前状态信息。

例如,当检测到所述终端与电源适配器建立电性连接时,启动语音识别程序,以便随时接收用户发出的语音指令。如果所述终端接收到的语音指令中包括与充电相关的语音信息,确定接收的语音指令为语音充电指令。例如,接收到的语音指令为“50W充电”、 “我要快速充电”或“小功率充电”时,确定接收的是语音充电指令。
S202、基于所述语音充电指令,确定所述用户设置的充电参数;
通常情况下,通过对所述语音充电指令的内容进行识别,得到文本内容,然后从文本内容中提取所述充电参数。例如,文本内容为“50W充电”,则可以确定所述用户设置的充电参数为“50W”;再如,文本内容为“我要快速充电”,则可以确定所述用户设置的充电参数为“快速充电”。
需要说明的是,步骤S201和步骤S202为“获取所述用户设置的充电参数”的一种实施示例。
S203、基于所述用户设置的充电参数,确定与所述充电参数对应的第一充电功率;
S204、获取所述终端当前的电池温度和电池电量;

在本申请实施例中,用户可以通过语音充电指令设置充电参数。这样,通过开通语音通道,便于用户自行且快速地设置所述终端当前所需的充电功率,从而满足用户在不同应用场景下,对充电速度和发热程度的要求。
本申请实施例提供另一充电方法,该方法包括步骤S301至步骤S308:
S301、在检测到对所述终端进行充电的条件满足时,显示预设的充电功率设置界面,所述充电功率设置界面包括至少一项可供所述用户选择的充电功率档位;
例如,确定所述终端与电源适配器建立电性连接时,显示所述充电功率设置界面,以供用户在所述充电功率设置界面选择当前想要的充电功率;在其他实施例中,用户可以通过点击用于调用所述充电功率设置界面的按键,来触发显示所述充电功率设置界面。例如,图2A所示,用于调用所述充电功率设置界面的按键20可以显示在应用程序为“设置”的应用界面21中;如图2B所示,按键20还可以隐藏在通知栏22中,用户可以通过上拉操作或者下拉操作调出通知栏22,从而点击按键20,触发显示所述充电功率设置界面。对于终端而言,如果接收到操作指令,所述操作指令用于指示所述终端显示所述充电功率设置界面,则基于所述操作指令,显示所述充电功率设置界面。
在实际应用中,例如,图3A所示,所述充电功率设置界面31上包括“大功率充电”、“中功率充电”、“小功率充电”这3个充电功率档位。再如,图3B所示,所述充电功 率设置界面32上包括20W、30W、40W、50W、60W、70W、80W、90W、100W这9个充电功率档位。
S302、在所述充电功率设置界面上接收选择指令,选择指令用于指示所述终端以所述选择指令所指示的充电参数对所述电池组件进行充电;
S303、基于所述选择指令,确定所述用户设置的充电参数;
一般来说,通过确定在所述充电功率设置界面上接收所述选择指令的位置,即可确定所述用户所选择的充电功率档位(即所述用户设置的充电参数)。
需要说明的是,步骤S301至步骤S303为“获取所述用户设置的充电参数”的另一种实施示例。
S304、基于所述用户设置的充电参数,确定与所述充电参数对应的第一充电功率;
S305、获取所述终端当前的电池温度和电池电量;
S306、基于所述电池温度和所述电池电量,确定第二充电功率,所述第二充电功率为所述电池组件当前能够接受的最大安全充电功率;
S307、基于所述第一充电功率和所述第二充电功率确定所述目标充电功率;
S308、以所述目标充电功率为所述终端的电池组件进行充电。
在本申请实施例中,用户可以通过充电功率设置界面设置充电参数,从而自行控制所述终端的当前充电功率,满足用户在不同应用场景下,对充电速度和发热程度的要求。
本申请实施例提供另一充电方法,该方法包括步骤S401至步骤S409:
S401、在检测到对所述终端进行充电的条件满足时,获取所述终端的当前状态信息;
S402、基于所述电池温度和所述电池电量,确定第二充电功率,所述第二充电功率为所述电池组件当前能够接受的最大安全充电功率;
S403、确定所述当前状态信息中是否包括所述用户设置的充电参数;如果是,执行步骤S404;否则,执行步骤S406;
S404、基于所述用户设置的充电参数,确定与所述充电参数对应的第一充电功率;
举例来说,如果所述用户设置的充电参数不是具体的充电功率数值,而是用于指示充电速度的参数(例如,快速充电、慢速充电、小功率充电、大功率充电等),那么,可以根据预设的功率映射表,确定所述用户设置的充电参数对应的第一充电功率。例如,表1所示,快速充电对应的第一充电功率为90瓦特(Watt,W),中速充电对应的第一充电功率为60W,慢速充电对应的第一充电功率为30W,当用户设置的充电参数为快速充电时,从表1中可以确定快速充电对应的第一充电功率为90W。
表1
充电参数 第一充电功率(瓦特)
快速充电 90
中速充电 60
慢速充电 30
S405、基于所述第一充电功率和所述第二充电功率,确定所述目标充电功率,然后进入步骤S409;
可以理解地,用户设置的充电参数可能不在所述终端当前允许的充电功率范围内,所述用户设置的充电参数可能不满足所述终端的当前充电条件,例如,用户设置的第一充电功率大于电池组件当前允许的最大安全充电功率,如果此时以用户设置的第一充电功率给电池组件进行充电,可能会损伤电池组件的电芯性能,甚至导致电芯爆炸。因此,这里,基于所述第一充电功率和所述第二充电功率,确定所述目标充电功率,能够在实现充电功率的自动调整,均衡充电速度和发热程度对用户使用终端时的影响的前提下,确保充电安全。
另外,用户设置的第一充电功率可能并不符合电池组件的当前充电条件,例如,用户设置的第一充电功率大于电池组件当前允许的最大安全充电功率,如果此时以用户设置的第一充电功率给电池组件进行充电,可能会损伤电池组件的电芯性能,甚至导致电芯爆炸。
需要说明的是,步骤S404和步骤S405为“基于所述当前状态信息,确定目标充电功率”的一种实施示例。
例如,在其他实施例中,对于步骤S405,所述基于所述第一充电功率和所述第二充电功率,确定所述目标充电功率,可以包括:将所述第一充电功率与所述第二充电功率进行比较;如果所述第一充电功率小于所述第二充电功率,将所述第一充电功率确定为所述目标充电功率;如果所述第一充电功率大于或等于所述第二充电功率,将所述第二充电功率确定为所述目标充电功率。
S406、获取所述终端的其他当前状态信息,所述其他当前状态信息至少包括以下之一:当前运行状态、所述终端与电源适配器的连接方式;
可以理解地,终端的当前运行状态与终端产生的能耗呈现正相关,举例来说,终端当前运行的应用越多或者终端的内存开销越大,终端的负载消耗的能力就越多,随之带 来的发热现象也就越严重。在其他实施例中,可以获取终端的内存开销,通过内存开销表征终端的当前运行状态。
目前,所述终端与所述电源适配器的连接方式,如图4A所示,通常情况下为电源适配器40通过电源线41与终端42建立电性连接。在本申请实施例中,提供另一种连接方式,如图4B所示,电源适配器40通过散热装置43与终端42建立电性连接,这样,通过散热装置43可以对正在进行充电的终端42进行散热,从而及时减少终端42在充电过程中所产生的热量。在实际应用中,散热装置43可以是风扇、制冷装置等。在散热装置43插入终端42的充电接口之后,散热装置43可以通过与终端42之间的无线通信链路(例如,蓝牙链路、WIFI链路、NFC链路等),给终端42发送提示信号,以告知终端42当前插入所述终端42的装置为散热装置。例如,所述提示信号中包括散热装置43的标识码,终端42根据接收的提示信号,即可确定是否是通过散热装置与电源适配器建立电性连接的。
另外,需要说明的是,如图4B所示,散热装置43上设置有与终端42的充电接口匹配的插头,例如,终端42的充电接口上具有电源引脚VBUS、D+引脚、D-引脚和接地引脚GND,对应地,散热装置43上的插头上也具有这四个引脚。通过散热装置43上的插头与终端42连接,可以最大限度地缩短散热装置43与终端42之间的距离,从而充分利用散热装置43的散热能力,快速地终端42进行降温。
电源适配器40与终端42可以通过通信接口(例如图4B所示的终端42的充电接口上的D+引脚所在的线路421)进行信息交互,也就是,由散热装置43进行中转;当然,电源适配器40与终端42还可以通过无线通信方式进行信息交互。电源适配器40在对终端42进行充电时,电源适配器40的输出电流,经过散热装置之后,流入终端42,为终端42上的电池组件进行充电。
S407、基于所述第二充电功率和所述其他当前状态信息,确定第三充电功率;
可以理解地,所述当前状态信息中没有所述用户设置的充电参数时,即,所述用户没有设置所述终端当前的充电参数,通过步骤S407和步骤S408,在保证充电安全的前提下,实现终端当前充电功率的自动调整;这样,当终端处于充电状态时,如果用户没有使用该终端,通过步骤S407和步骤S408,可以提高充电速度,缩短充电时长;当终端处于充电状态时,如果用户正在使用该终端,通过步骤S407和步骤S408,可以均衡终端的充电速度和发热程度对用户使用终端时的影响,提高用户充电体验。
S408、基于所述第二充电功率和所述第三充电功率,确定所述目标充电功率;
可以理解地,如果所述当前状态信息中不包括所述用户设置的充电参数时,可以基于所述其他当前状态信息,确定目标充电功率,以实现充电功率的自动调整,均衡充电速度和发热程度对用户使用终端时的影响,提高用户充电体验。
需要说明的是,步骤S406至步骤S408为“基于所述当前状态信息,确定目标充电功率”的另一种实施示例。
在其他实施例中,如果所述当前状态信息中不包括所述用户设置的充电参数时,也可以直接将所述第二充电功率确定为所述目标充电功率,从而提高所述电池组件的充电效率,减少充电时长。
S409、以所述目标充电功率为所述终端的电池组件进行充电。
本申请实施例提供又一充电方法,该方法包括步骤S501至步骤S508:
S501、在检测到所述终端与电源适配器建立电性连接之后,获取所述终端的当前状态信息;所述当前状态信息中包括所述终端当前的电池温度、电池电量和内存开销;
这里,需要说明的是,由于用户没有设置充电参数,所以,在获取所述终端的当前状态信息时,无法获取到用户设置的充电参数,即,所述当前状态信息中没有用户设置的充电参数。
S502、基于所述电池温度和所述电池电量,确定第二充电功率,所述第二充电功率为所述电池组件当前能够接受的最大安全充电功率;
S503、确定所述终端是否通过散热装置与所述电源适配器建立电性连接;如果是,执行步骤S504;否则,执行步骤S507;
例如,所述终端可以通过解析与其直连的装置发送的通信信号,来确定是否通过散热装置与电源适配器建立电性连接。
可以理解地,当所述终端连接有所述散热装置时,确定的第二充电功率(即最大安全充电功率),相比于所述终端没有连接散热装置时,前者可以获得更大的第二充电功率。因此,当所述终端连接有所述散热装置时,如果使用所述第二充电功率对所述电池组件进行充电,能够更加快速地完成充电。
S504、获取所述散热装置的散热参数,所述散热参数用于表征所述散热装置的散热能力,然后进入步骤S505;
例如,所述散热参数可以是散热装置的额定功率、散热方式等,额定功率越大,表明散热能力越强;散热方式,例如,可以是风扇散热,也可以是通过制冷散热等,相对来说,制冷散热的散热能力较强。在其他实施例中,可以定时获取所述终端的机身温度 或者电池温度,然后计算机身温度或者电池温度的下降速度,将所述机身温度或者电池温度的下降速度确定为所述散热参数。
S505、基于所述第二充电功率、所述散热参数和所述内存开销,确定所述第三充电功率,然后进入步骤S507;
可以理解地,所述当前状态信息中没有所述用户设置的充电参数时,在用户边充电边使用终端的应用场景下,如果直接以第二充电功率(即电池组件当前的最大安全充电功率)为电池组件进行充电,电池的持续升温、发烫,可能会给用户带来不好的充电体验。因此,在本申请实施例中,结合散热参数和/或内存开销来确定目标充电功率,从而有效均衡终端的充电速度和发热程度对用户使用终端时的影响,提高用户充电体验。
例如,可以确定第二充电功率、散热参数、内存开销分别对目标充电功率的影响程度,基于每一当前状态的影响程度,来确定所述第三充电功率。
S506、基于所述第二充电功率和所述内存开销确定所述第三充电功率;
S507、基于所述第二充电功率和所述第三充电功率,确定所述目标充电功率;
例如,比较所述第二充电功率和所述第三充电功率的大小关系,如果所述第三充电功率大于或等于所述第二充电功率,则将所述第二充电功率确定为目标充电功率;如果所述第三充电功率小于所述第二充电功率,则将所述第三充电功率确定为目标充电功率;这样,使目标充电功率始终小于或等于电池组件当前的最大安全充电功率,确保充电安全。
需要说明的是,步骤S502至步骤S507为“确定第三充电功率”的一种实施示例。
S508、以所述目标充电功率为所述终端的电池组件进行充电。
在其他实施例中,对于步骤S505,基于所述第二充电功率、所述散热参数和所述内存开销,确定所述第三充电功率,可以通过如下步骤S5051至步骤S5052实现:
S5051、从预设的第一功率增量映射表中,确定与所述内存开销对应的第一功率增量;
可以理解地,所述终端当前的内存开销越大,负载消耗的能量就越多,随之带来的发热现象也就越严重。因此,在设置所述第一功率增量映射表时,通常将第一功率增量设置为负值。例如,表2所示,内存开销小于1GB时,对应的第一功率增量为0;内存开销属于[1.0GB,1.5GB)时,对应的第一功率增量为-5W;内存开销属于[1.5GB,2.0GB)时,对应的第一功率增量为-10W。
表2
内存开销 第一功率增量
[0,1GB) 0
[1.0GB,1.5GB) -5W
[1.5GB,2.0GB) -10W
…… ……
S5052、从预设的第二功率增量映射表中,确定与所述散热参数对应的第二功率增量;
可以理解地,散热装置的散热能力越强,终端的机身温度或者电池温度下降的越快。因此,在设置所述第二功率增量映射表时,通常将第二功率增量设置为正值。例如,所述散热装置中设置有风扇时,对应的散热参数通过风扇的转速来表征,设置的第二功率增量映射表,如表3所示,风扇转速小于2000转/min时,对应的第二功率增量为5W,风扇转速属于[2000转/min,3000转/min)时,对应的第二功率增量为10W;风扇转速属于[3000转/min,4000转/min)时,对应的第二功率增量为15W。
表3
风扇转速 第一功率增量
[0,2000转/min) 5W
[2000转/min,3000转/min) 10W
[3000转/min,4000转/min) 15W
…… ……
S5053、将所述第二充电功率、所述第一功率增量和所述第二功率增量进行累加,得到所述第三充电功率。
在其他实施例中,如果所述终端与所述电源适配器的连接方式为所述终端通过电源线与所述电源适配器建立电性连接时,基于所述第二充电功率和所述内存开销,确定所述第三充电功率。例如,将所述第二充电功率和所述第一功率增量进行累加,得到所述第三充电功率。
一般来说,手机在进行大功率快速充电时,功率越大,充电越快,但是发热也越严重,充电时引起的发热现象会给用户带来一些不好的体验。在本申请实施例中,阐述一 种手机和用户交互的方式,即,用户在不同的应用场景中,可以自行设置不同的充电功率,来平衡充电速度和发热程度对自己使用手机的影响,从而带来更好的使用体验。
例如,用户此时急需把手机充满电,可以忍受更严重的发热。也就是,快速充电是主要需求,发热递变为次要需求,用户此时可以选择最大功率进行充电,手机会以安全范围内的最大功率进行快速充电。
再如,在给手机充电时,用户正在玩游戏,此时不能忍受手机发热,发热递变为主要需求,充电速度变为次要需求,用户此时可以选择低功率进行充电,手机会以安全范围内最接近用户选择的功率进行快速充电。
而目前常见的大功率充电方案中,对充电功率的控制在手机的后台,用户无法自行控制。本申请实施例中,可以让用户在不同的应用场景中,自行设置不同的充电功率,来平衡充电速度和发热程度对自己使用手机的影响,从而带来更好的使用体验。
例如,在手机上显示预设的充电功率设置界面,用户选择的按钮(即充电功率档位)可以是具体的数值,比如,20W、30W、40W、50W、60W、70W、80W、90W、100W等,也可以是大功率、中功率、小功率这种不具体的数值。
用户选择的按钮展现方式可以是弹框选择,也可以隐藏在通知栏供用户选择,也可以在手机的“设置”APP中的子选项中去选择。
假设用户可选择的充电功率P_user为20W、30W、40W、50W、60W、70W、80W、90W、100W;后台可设置的充电功率P_set为20W、30W、40W、50W、60W、70W、80W、90W、100W。用户把手机插入电源适配器进行充电时,在手机的用户界面(User Interface,UI)会出现选择充电功率的按钮供用户选择。
在不同的电池温度、电池电量条件下,后台计算出的当前最大安全充电功率为Pmax_set1,用户在手机界面选择的充电功率为P_user1。
若P_user1>=Pmax_set1,手机以当前最大安全充电功率Pmax_set1进行充电;
若P_user1<Pmax_set1,手机以当前用户选择的充电功率P_user1进行充电;
若用户不进行选择,手机会以当前最大安全充电功率Pmax_set1进行充电。
另外,需要说明的是,关于大功率充电的实现,可参考以下方式:
1、在不考虑手机发热的情况下,可直接通过增加电源适配器的输出功率实现。充电架构可以使用现在的快充架构(低压大电流),或者其它充电架构(高压小电流)。
2、在考虑手机发热,即需要控制手机的发热的情况下,可以增加一个额外的散热装置(例如,风扇、制冷散热等方式),对在充电的手机进行散热。手机、电源适配器 和散热装置的连接关系如图4B所示。手机可以通过各种方式(比如,感应、通信)检测散热装置是否存在,例如,接收散热装置发送的提示信号,根据提示信号携带的散热装置的标识码确定是否连接有散热装置。如果手机上连接有散热装置,即可确定采用大功率充电(可为超过50W的充电功率)对手机进行充电。此时,可结合上述的用户交互进行充电功率的控制。
需要说明的是,电源适配器和手机之间的通信方式,可以是通过通信接口,由散热装置进行中转;也可以是手机和电源适配器直接无线通信交互。电源适配器对手机进行充电,也可以是通过散热装置中的通路中转。另外,散热装置如果是需要供电的,也可以由适配器直接进行供电。
基于前述的实施例,本申请实施例提供一充电装置,该装置包括各模块、以及各模块所包括的各单元,可以通过终端中的处理器来实现;当然也可通过具体的逻辑电路实现;在实施的过程中,处理器可以为中央处理器(CPU)、微处理器(MPU)、数字信号处理器(DSP)或现场可编程门阵列(FPGA)等。
图5为本申请实施例充电装置的组成结构示意图,如图5所示,所述充电装置500包括当前状态信息获取模块501、目标充电功率确定模块502和充电模块503,其中:

目标充电功率确定模块502,用于基于所述当前状态信息,确定目标充电功率;
充电模块503,用于以所述目标充电功率为所述充电装置的电池组件进行充电。
