- FIG. 5 is a flowchart of the fast charging control method in the embodiment. As shown in FIG. 5, the method provided in this embodiment includes the following steps.
- step 1010 when the terminal charging chip output voltage Vout reaches the maximum battery operating voltage Vmax_bat for the first time, the voltage Vchar_bat actually added to the battery cell is definitely less than Vmax_bat, that is, the battery enters the constant voltage charging phase.

- the charging current is Ichar_temp at this time, since the charging line from the charging chip to the battery cell has a trace impedance and a connector contact resistance (the total impedance is Rdc), it is added to the battery cell.
- the voltage is:
- Vchar_bat Vout-Ichar_temp ⁇ Rdc (1-1)

- Rdc's measurements are throughout the charging process, and real-time measurements are more tracking and correction, ensuring that the voltage applied across the battery is within safe limits.
- the measurement interval of Rdc can be adjusted according to the actual situation.
- Rbat represents the battery-related resistance, including the internal resistance of the battery and the damping of the charge due to the charging chemical reaction. Since each measurement of Rdc is short-lived, the variation of Rbat at different Vouts and during the measurement can be ignored.

- Vout and Ichar1 reach the relationship of the formula (1-4), so that the voltage applied to the battery cell reaches Vmax_bat.
- the charging chip output voltage is increased from Vmax_bat to Vmax_bat+Ichar1*Rdc; the corresponding voltage applied to the battery cell is increased from Vbat_char to Vmax_bat while still maintaining a safe voltage range.
- the system error needs to be considered in practical applications, and the threshold is set to have a safety margin. That is, the actual increase in the output voltage of the charging chip should be Ichar1*Rdc- ⁇ V. Where ⁇ V is the voltage error introduced by the actual system error.
- T1 (100%-C_bat)/Ichar1 (1-5)
- Vout and Ichar1 constraint relationships in the calculations in this section can also be given directly by hardware.
- real-time detection ensures that the voltage applied to the battery cell is Vmax_bat. In this way, we do not need complicated calculations, and directly give the corresponding Vout and Ichar1, and the corresponding T1 through real-time detection.
- step 1060 After T1 is calculated by step 1060, T1/x (x ⁇ 1) time is charged by Ichar1, and then step 1020 is performed again.
- the setting value of x can be larger.
- the setting of x may be fixed or may be appropriately adjusted according to relevant parameters.
- the actual set value will be smaller than the calculation here.
- the magnitude of the value used herein is determined by the error caused by the application scenario of the electronic device used and the total error caused by the device errors used by the plurality of modules.
- step 1070 charging is stopped.
- the software execution code is monitored with a timer to ensure that the charging chip output voltage is within the battery safe voltage range when the timer expires (ie, when the software is not controlled).

本公开实施例所提供的方法实施例可以在移动终端、计算机终端或者类似的运算装置中执行。以运行在移动终端上为例,图2是一实施例提供的一种充电方法的移动终端的硬件结构框图。如图2所示,移动终端20可以包括一个或多个(图2中仅示出一个)电池202、设置为连接电池202与电源装置206的线路204、以及设置为给电池202供电的电源装置206。本领域普通技术人员可以理解,图2所示的结构仅为示意,并不对上述电子装置的结构造成限定。例如,移动终端20还可包括比图2中所示更多或者更少的组件,或者具有与图2所示不同的配置。

电源装置206设置为给电池202充电或者是给其他部件供电。在一个实例中,电源装置206包括可以是移动电源或者固定电源。
在一实施例中,本公开的方法还可以应用在如图3中所示的硬件装置中,包括以下内容:
如图3所示,电池为电子产品供电和存储充电模块提供的电能。充电模块,设置为为电池充电和检测电池一项或多项参数,并与控制模块通信。控制模块设置为对整个电子产品进行指令控制,包括输入、输出、存储以及数据分析等一项或多项命令和任务。输入、输出和存储等其他模块,设置为实现电子产品的用户交互、数据存储以及网络通信等其他功能。充电线路为充电模块与电池之间的电能传输线路,包括电子产品上的信号走线和连接器,也包括电池上的走线、连接器和电极等。电池检测反馈信号用于电池身份信息及其他电气参数反馈。包括电池温度、电池厂家信息及其他电气数据等。

在本实施例中提供了一种充电方法,应用于上述移动终端,如图4所示,该方法包括如下步骤。
在步骤402中,在对电池进行充电的过程中,在确定电池进入恒压充电阶段后,增加充电芯片的输出电压。
在步骤404中,利用增加后的充电芯片的输出电压对电池进行充电。
通过上述步骤,由于终端在对电池进行充电的过程中,如果确定了电池进入恒压充电阶段,则增加充电芯片的输出电压;并利用增加后的充电芯片的输出电压对电池进行充电。因此,可以使电池在最后的充电阶段中,不会因为充电电压低而造成充电指标不达标,造成充电时间长的问题,达到缩短电池充电时间,以及充电指标达标的效果。
在一实施例中,上述步骤的执行主体可以为终端(比如手机、电脑或平板等),但不限于此。
在本实施例中,上述中的恒压充电阶段是指电池充电电流逐渐减少的阶段,即电池充入的电量不能成比例增加。本公开在增加充电电压之后,电池的充电电压不会逐渐降低,从而可以保证电池的正常充电,即充电电量与充电时间会成比例增加。可以减少相关技术中存在的电池充电的最后阶段,充电时间长的 问题。并且,本实施例中增加的电池电压不大于电池的最大安全电压,即将电池的电压增加到正常充电的电压即可,以保证电池充电时的安全性。
在一个实施例中,增加上述充电芯片的输出电压可以包括:检测电池的电池电量以及上述电池进入恒压充电阶段后的电池电压,并判断电池是否支持大于上述电池的最大工作电压的充电电压;根据检测到的电池电量、电池电压以及判断结果增加上述充电芯片的输出电压。在本实施例中,需要对电池是否进入恒压充电阶段进行判断,在确定电池进入恒压充电阶段,并且,电池的电量是没有充满的状态时,对电池执行充电相关操作。
在一个实施例中,根据检测到的上述电池电量、电池电压以及判断结果增加上述充电芯片的输出电压可以包括以下之一:在检测到的电池电量小于预定值、电池电压小于最大工作电压,且判断结果为上述电池不支持大于上述最大工作电压的充电电压的情况下,确定最大工作电压为增加后的充电芯片的输出电压;根据确定的上述增加后的充电芯片的输出电压增加上述充电芯片的输出电压;在上述检测到的电池电量小于预定值、电池电压小于上述最大工作电压,且上述判断结果为上述电池支持大于上述最大工作电压的充电电压的情况下,确定上述电池正常充电阶段的电压为增加后的充电芯片的输出电压;根据确定的上述增加后的充电芯片的输出电压增加上述充电芯片的输出电压。在本实施例中,上述中的电池电量的预设值可以是电池的100%,也可以是设定的电量值。并且,在对上述中的电池进行充电时,需要保证电池的电压处于安全的范围内,可以通过设置实时检测反馈机制对电池电压进行实施检测反馈。根据反馈的电池电压,不断增加输出电压,直到达到最大工作电压。并根据增加后的充电芯片的输出电压对电池进行充电。
在一个实施例中,利用增加后的上述充电芯片的输出电压对上述电池进行充电可以包括以下之一:在上述判断结果为上述电池不支持大于上述最大工作电压的充电电压的情况下,计算增加了输出电压的充电芯片的充电电流;利用上述充电电流和上述增加后的充电芯片的输出电压对上述电池进行充电;在上述判断结果为上述电池支持大于上述最大工作电压的充电电压的情况下,利用上述电池正常充电阶段的电压和上述电池正常充电阶段的电流对上述电池进行充电。在一实施例中,上述正常充电阶段为上述电池在进入上述恒压充电阶段之前的充电阶段。在本实施例中,在对电池进行充电的阶段中,也需要保证电池的充电电流处于安全的范围之内。
在一个实施例中,利用增加后的上述充电芯片的输出电压对上述电池进行充电时,上述方法还可以包括以下之一:在上述判断结果为上述电池不支持大于上述最大工作电压的充电电压的情况下,利用上述充电电流和上述电池电量计算出用于检测上述充电芯片的输出电压的第一检测时间,根据上述第一检测时间周期性地检测上述电池电压和/或电池电量;在上述判断结果为上述电池支持上述大于上述最大工作电压的充电电压的情况下,利用上述电池电量和上述电池正常充电阶段的电流计算出用于检测上述充电芯片的输出电压的第二检测时间,根据上述第二检测时间周期性地检测上述电池电压和/或电池电量。在本实施例中,在对电池进行充电的过程中,需要周期性地对电池电压进行检测,以保证电池的安全性。上述中的第一检测时间和第二检测时间即是对电池进行检测的时间周期。
在一个实施例中,在确定上述电池进入恒压充电阶段后,上述方法还可以包括以下之一:在确定电池电量为充满状态的情况下,停止对上述电池进行充电;在确定上述电池电压大于或者等于上述电池的最大工作电压的情况下,停止对上述电池进行充电。在本实施例中,上述中的对电池停止充电的条件可以根据电池的性能和需要进行设定。
综上,通过对电池最后阶段充电的管理,可以使得电池快速地充电,又可以保证电池的安全性,增加了用户体验。
下面结合实施例对本公开进行说明:
在符合本公开的一个实施例中:
下面以电子设备(对应上述中的终端或移动终端)的电池充电为例进行说明:本实施例是在电子设备电池充电电流逐渐减小阶段实现大电流充电,本实施例提供的充电方法包括以下内容:
电子设备电池的充电电压的设置结合电量计所检测的电池电量,在电池电量不满的情况下,即是在确定电池进入恒压充电阶段后(恒压充电阶段是指电池充电电流逐渐减少的阶段,即电池充入的电量不能成比例增加)继续增加电池的充电电压,而不限制在电池最大工作电压。从而增加最后阶段充电电流,通过电量计检测电池电量和计算(或反馈)的电芯处的真实电压是否达到最大工作电压,作为停止充电判断条件之一。本实施例中的电池可以是干电池、铅蓄电池或者锂电池。并且,在本实施例中,还可以在终端或其他电子设备上引入除上述类型之外的电池,采用更高耐压的电极材料和电解质材料。在电池充 电电流逐渐减少的阶段通过增加充电电压,保证电池接近充满时有足够的充电电流,减少充电时间。
图5是本实施例中的快速充电控制方法的流程图,如图5所示,本实施例提供的方法包括以下步骤。
在步骤1010中、终端充电芯片输出电压Vout第一次达到电池最大工作电压Vmax_bat时,实际加到电池电芯的电压Vchar_bat肯定小于Vmax_bat,即是电池进入了恒压充电阶段。上述中的Vout是用于给终端进行充电的最大电压,进入恒压充电阶段后,电池的充电电压会不断减小。
如图6所示,如果此时充电电流是Ichar_temp,则由于从充电芯片到电池电芯间充电线路有走线阻抗和连接器接触阻抗等(总的阻抗是Rdc),加到电池电芯的电压为:
Vchar_bat=Vout-Ichar_temp×Rdc (1-1)
图6中充电线路阻抗引起Vout与Vchar_bat不一致。
在步骤1020中,读取用于测量电池电量的电量计,判断电池电量C_bat是否满足C_bat=100%,若满足则转入步骤1070,若不满足,则转入步骤1030。
在步骤1030中,暂时停止充电,并检测电池电压Vbat是否满足Vbat>=Vmax_bat,若满足则转入步骤1070,若不满足,则转入步骤1040。
步骤1020和步骤1030用于判断电池电量状态和开路电压(零负载电压)状态,确保电池继续充电是安全的。在电池的恒压充电阶段,需要不断地检测充电电压的安全,即需要保证在电池的整个充电阶段电池的性能是安全的。
在步骤1040中,判断电池种类,即判断加到电芯上的电压是否能超过电芯最大工作电压,如果能,则转入步骤1050,如果不能,则转入步骤1060。在检测电池的充电电压时,还需要检测电池的充电电压是否与电池的种类相匹配。避免超过不同的电池种类所能承受的最大充电电压。比如:通用的锂离子电池,加到的电芯的电压不能超过最大工作电压Vmax_bat。对于其他新型电池,则可能存在加到电池的电压可以超过Vmax_bat。
步骤1050对应支持高压充电的新型电池充电的步骤,在步骤1050中,根据电池电量C_bat和停止充电时测得的电池电压Vbat,计算得出按原充电电流Ichar0充电T0时间后才能充满,相应的T0为:
T0=(100%-C_bat)/Ichar0 (1-2)
计算得出T0后,在Ichar0充电T0/x(x≥1)时间后,再次对电池的安全性 进行检测,即步骤1020循环操作。为实现循环检测,使得电池的电量逼近充满状态,确保对电池充电电压控制的准确性和安全性,x的设定值可以更大。在一实施例中,x的设定可以是固定的,也可以是根据相关参数进行适当调整的。在一实施例中,相关参数包括电池的性能或者是电压的变化。
步骤1060是对应不支持高压充电的锂离子等电池进行充电的步骤。在步骤1060中,计算得出加到电池两端的电压Vchar_bat=Vmax_bat时的充电电流Ichar1,并计算得出采用Ichar1充电T1时间后才能充满。
首先Rdc表示充电芯片到电池间的走线阻抗和接触阻抗等,电池的电压被用户使用过程中不是恒定不变的,在充电时需精确计算。Rdc的测量是贯穿整个充电过程的,实时的测量更多是跟踪和修正,确保加到电池两端的电压是在安全范围之内的。Rdc的测量间隔可根据实际情况进行调整。
如图7所示,Rbat表示电池特性相关的电阻,包括电池内阻和由于充电化学反应对电荷的阻尼。由于Rdc每一次的测量是短暂的,Rbat在不同Vout下和测量过程中的变化可以忽略。
通过式(1-3)测量一系列不同Vout下的Ichar_temp,拟合得出Rdc:
Vout_1=Ichar_temp_1×(Rdc+Rbat)
Vout_2=Ichar_temp_2×(Rdc+Rbat)
Vout_N=Ichar_temp_N×(Rdc+Rbat) (1-3)
在有了精确的Rdc后,可以计算得出加到电芯的电压Vchar_bat=Vmax_bat,充电芯片对应输出的电压Vout与Ichar1的约束关系为:
Vout=Ichar1×Rdc+Vmax_bat (1-4)
通过调节充电芯片,使Vout和Ichar1达到式(1-4)的关系,这样就实现了加到电池电芯的电压达到Vmax_bat。
采用上述方法,在进入恒压充电阶段后,充电芯片输出电压从Vmax_bat增加到Vmax_bat+Ichar1*Rdc;相应的加到电池电芯的电压从Vbat_char增加到了Vmax_bat,而仍然保持在安全的电压范围。在一实施例中,在实际应用需要考虑到系统误差,阈值设定要留有安全余量。也就是充电芯片输出电压实际增加量应为Ichar1*Rdc-ΔV。其中,ΔV为实际系统误差引入的电压误差。
最后T1根据式(1-5)计算
T1=(100%-C_bat)/Ichar1 (1-5)
在一实施例中,本部分的计算中Vout和Ichar1约束关系也可以通过硬件手 段直接给出。比如我们可以在电芯的正负极处额外引出检测信号,在调节Vout时,实时检测确保加到电池电芯的电压为Vmax_bat。这样我们不用复杂的计算,通过实时检测直接给出相应的Vout和Ichar1,以及对应的T1。
通过步骤1060计算得出T1后,按Ichar1充电T1/x(x≥1)时间后,再次进行步骤1020循环。为实现循环检测,逐渐使电池的电量逼近充满状态,确保电池的充电电压控制的准确性和安全性,x的设定值可以更大。在一实施例中,x的设定可以是固定的,也可以是根据相关参数进行适当调整的。
考虑到计算误差和安全性问题,实际设置的值会比此处计算要小。在一实施例中,此处所采用值的大小决定于所用电子设备应用场景所带来的误差和多个模块所用器件误差综合得出的总误差大小。
在步骤1070中,停止充电。
在一实施例中,考虑到电池充电的安全性,防止在外界硬件参数突然变化而软件失控,需要增加保护手段。包括,用计时器对软件执行代码进行监控,确保在计时器超时(也就是软件不受控制时)充电芯片输出电压在电池安全电压范围以内。在一实施例中,也可以采用上述所说,在电芯额外引出检测信号,作为充电安全停止的出发事件。
在符合本公开的一个实施例中:
下面根据实际终端设计中的参数,给出本公开中对于锂离子电池充电方法中涉及的计算进行举例。在计算之前,为了便于定量计算,首先确定两个近似。
1)相关技术中,充电电流逐渐减少的阶段中电流减少速度也越来越慢,为计算线性减少的近似值,设定电流减少的速度是恒定的。
2)由于电池的电解质内部不是时刻均匀的,电解质在实际的充电中阻尼作用模型也是复杂变化的,下面定量计算中不考虑电解质阻尼作用的变化。但是实际算法中要在充电过程中时刻进行检测和计算,以确保充电参数(电池最大电压等)是可控的。
设定最大充电电流是Ichar_max=1安培(A),电池最大工作电压Vmax_bat=4.3伏特(V),从充电芯片到电池电极的整个走线电阻、接触电阻和串联期间电阻等总电阻为Rdc=100毫欧(mohm)。
相关技术的充电方案中,Vout=4.3V,Vchar_bat=4.3V-1A*100mohm=4.2V,充电电流开始减少,从充电电流开始减少到电池充满,平均充电电流Ichar_average=Ichar_max/2=500毫安(mA)。
采用本公开方案,达到上述电流逐渐减少状态时,根据Rdc值增加Vout,保证Vout=Vchar_bat+Ichar_temp*100mohm成立。在不考虑电解质不均匀的情况下,加到电解质两端电压达到4.3V之前电解质能维持吸收1A的充电电流。从而整个充电的平均电流能按照1A来计算,是上述的充电电流较少的阶段平均电流的2倍,这个阶段的充电时间可以减少50%。
如果从充电电流开始减少到电池充满的这段时间,占整个充电时间的30%,那么采用本方案的充电方法比相关技术中的充电方案花费的时间少15%。
采用本方案后,终端电池充电曲线如图8所示。图8右边部分,给出了采用本方案后电池端电压电流变化走向示意,以及相对相关技术中所采用方案所节省的时间部分。
以上所述控制方法包括终端电池充电控制,但不限制于终端的电子产品,任何具有充电智能控制电子设备都可以采用此方案所提出的控制方法。
综上所述,本实施例通过实时跟踪终端或其他电子产品硬件状态,校准调整充电参数,减少终端或其他电子产品电池最后阶段的充电时间,从而减少电池的整体充电时间。实现保证安全性前提下,不影响续航能力和不增加成本情况下实现电池更快充电,提升用户体验。在采用更高耐压材料的电池上面,采用本实施例的技术方案,将有更大的技术优势和商用价值。
通过以上的实施方式的描述,本领域的技术人员可以了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现,当然也可以通过硬件,但很多情况下前者是更佳的实施方式。基于这样的理解,本公开的技术方案本质上可以以软件产品的形式体现出来,该计算机软件产品存储在一个存储介质(如只读存储器(Read-Only Memory ROM)/随机存取存储器(Random Access Memory,RAM)、磁碟、光盘)中,包括一个或多个指令用以使得一台终端设备(可以是手机、计算机、服务器或者网络设备等)执行本公开任意实施例所述的方法。
