Description
本申请涉及电子技术领域,尤其涉及一种电子设备及其电池充电方法、以及计算机可读存储介质。The present application relates to the field of electronic technologies, and in particular, to an electronic device and a battery charging method thereof, and a computer readable storage medium.
目前,手机、平板电脑等电子设备一般都使用锂电池进行供电,现有的锂电池的充电过程一般分为预充电、恒流充电、恒压充电三个阶段。其中,在预充电阶段,充电电压与充电电流迅速攀升,充电持续时间很短;在恒流充电阶段,充电电压缓慢增大,充电电流保持不变,这个阶段充入电池的能量可达到电池总电量的70%;在恒压充电阶段,充电电压保持不变,充电电流逐渐减小,直到到达截止电流时,停止充电。At present, electronic devices such as mobile phones and tablet computers generally use lithium batteries for power supply. The charging process of existing lithium batteries is generally divided into three stages: pre-charging, constant-current charging, and constant-voltage charging. Among them, in the pre-charging stage, the charging voltage and the charging current rise rapidly, and the charging duration is very short; in the constant current charging phase, the charging voltage is slowly increased, the charging current remains unchanged, and the energy of the battery charged at this stage can reach the total battery. 70% of the power; in the constant voltage charging phase, the charging voltage remains unchanged, the charging current is gradually reduced, and the charging is stopped until the off current is reached.
由于在恒流充电阶段电池的充电功率等于充电电流与充电电压的乘积,而充电电流保持不变,充电电压一般在恒流充电阶段结束时才达到峰值,可见,恒流充电阶段的电池的充电功率还有一定的提升空间。Since the charging power of the battery in the constant current charging phase is equal to the product of the charging current and the charging voltage, and the charging current remains unchanged, the charging voltage generally reaches a peak at the end of the constant current charging phase. It can be seen that the charging of the battery in the constant current charging phase is observed. There is still room for improvement in power.

It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.
请参阅图1,为本申请实施方式提供的一种电池充电方法的流程示意图。所述电池充电方法应用于电子设备中,其中,所述电子设备可以是智能手机、PDA、平板电脑等计算机设备。应说明的是,本申请实施方式的所述电池充电方法并不限于图1所示的流程图中的步骤及顺序。根据不同的需求,所示流程图中的步骤可以增加、移除、或者改变顺序。如图1所示,所述电池充电方法包括如下步骤:Please refer to FIG. 1 , which is a schematic flowchart diagram of a battery charging method according to an embodiment of the present application. The battery charging method is applied to an electronic device, wherein the electronic device may be a computer device such as a smart phone, a PDA, or a tablet computer. It should be noted that the battery charging method of the embodiment of the present application is not limited to the steps and the sequence in the flowchart shown in FIG. 1 . The steps in the illustrated flow diagrams can be added, removed, or changed in order, depending on the requirements. As shown in FIG. 1, the battery charging method includes the following steps:
步骤101,对电池进行充电。In step 101, the battery is charged.
步骤102,判断所述电池是否处于恒流充电状态。若所述电池处于恒流充电状态,则执行步骤103。若所述电池未处于恒流充电状态,则流程返回至步骤102。Step 102: Determine whether the battery is in a constant current charging state. If the battery is in a constant current charging state, step 103 is performed. If the battery is not in the constant current charging state, the flow returns to step 102.
步骤103,实时检测所述电池的充电电压。In step 103, the charging voltage of the battery is detected in real time.
如图2所示,电池的充电过程一般分为预充电阶段I、恒流充电阶段II、恒压充电阶段III。在预充电阶段I,电池电压值U
bat(即充电电压)与电池电流值I
bat(即充电电流)迅速攀升,充电持续时间很短;预充电阶段I结束后,进入所述恒流充电阶段II(快速充电阶段);在所述恒流充电阶段II,充电电压缓慢增大,充电电流保持不变;当充电电压达到截止电压U
max时,进入所述恒压充电阶段III,在所述恒压充电阶段III,充电电压保持不变,充电电流逐渐减小,直至电池充满电量。
As shown in FIG. 2, the charging process of the battery is generally divided into a pre-charging phase I, a constant current charging phase II, and a constant voltage charging phase III. In the pre-charging phase I, the battery voltage value U bat (ie, charging voltage) and the battery current value I bat (ie, charging current) rapidly rise, and the charging duration is short; after the pre-charging phase I ends, the constant current charging phase is entered. II (fast charging phase); in the constant current charging phase II, the charging voltage is slowly increased, the charging current remains unchanged; when the charging voltage reaches the cutoff voltage U max , the constant voltage charging phase III is entered, During the constant voltage charging phase III, the charging voltage remains unchanged and the charging current is gradually reduced until the battery is fully charged.
在恒流充电过程中,由于采用较大的电流充电,可以快速对电池进行充电,节省电池的充电时间。在所述恒压充电阶段III,由于电池的充电电流较小,并且随着时间的继续,充电电流会越来越小,因此在所述恒压充电阶段III的充电速度较慢。为了提高电池的充电速度,应该通过延长恒流充电的时间及/或缩短恒压充电的时间来达到要求。During the constant current charging process, the battery can be quickly charged due to the large current charging, which saves the charging time of the battery. In the constant voltage charging phase III, since the charging current of the battery is small, and as time continues, the charging current becomes smaller and smaller, so the charging speed in the constant voltage charging phase III is slower. In order to increase the charging speed of the battery, the requirement should be met by extending the time of constant current charging and/or shortening the time of constant voltage charging.
由于在所述恒流充电阶段II中,电池的充电电流保持不变,充电电压一般在所述恒流充电阶段II结束时才达到峰值,而电池的充电功率等于充电电流与充电电压的乘积,如图3的曲线P1所示,电池的充电功率也在所述恒流充电阶段II结束时才达到峰值。可见,在所述恒流充电阶段II的大部分时间 里,还没有充分利用电池的特性与充电设备的输出能力,电池的充电功率还有一定的提升空间,例如可将充电功率提升到如曲线P2所示的理想值。Since the charging current of the battery remains unchanged during the constant current charging phase II, the charging voltage generally reaches a peak at the end of the constant current charging phase II, and the charging power of the battery is equal to the product of the charging current and the charging voltage. As shown by the curve P1 of Fig. 3, the charging power of the battery also reaches a peak at the end of the constant current charging phase II. It can be seen that during most of the constant current charging phase II, the characteristics of the battery and the output capability of the charging device have not been fully utilized, and the charging power of the battery has a certain room for improvement, for example, the charging power can be increased to a curve. The ideal value shown in P2.
本申请实施方式中,主要针对恒流充电过程的充电电流进行逐步调整,在恒流充电阶段提升电池的充电功率,从而增加电池在恒流充电阶段所吸收的能量,可以减少在恒压充电阶段所需要吸收的能量,缩短恒压充电的时间,进而能够缩短总的充电时间,提高充电速度。In the embodiment of the present application, the charging current of the constant current charging process is gradually adjusted, and the charging power of the battery is increased during the constant current charging phase, thereby increasing the energy absorbed by the battery during the constant current charging phase, which can be reduced in the constant voltage charging phase. The energy that needs to be absorbed shortens the time of constant voltage charging, thereby shortening the total charging time and increasing the charging speed.
步骤104,判断检测到的所述充电电压是否达到所述电池的安全截止电压。若所述电池的充电电压未达到所述安全截止电压,则执行步骤105。若所述电池的充电电压达到所述安全截止电压,则执行步骤106。Step 104: Determine whether the detected charging voltage reaches a safe cutoff voltage of the battery. If the charging voltage of the battery does not reach the safety cutoff voltage, step 105 is performed. If the charging voltage of the battery reaches the safety cutoff voltage, step 106 is performed.
在本实施方式中,所述安全截止电压为所述电池进入恒流充电时设置的截止电压,所述安全截止电压一般小于所述电池的安全电压。其中,电池的安全电压由电池的电芯材料决定,例如,根据电芯材料的不同,电池的安全电压可以为4.3V,4.4V,4.5V等。可以理解的是,为了确保恒压充电的安全,安全截止电压一般设置为小于电池的安全电压,例如,安全截止电压可以比电池的安全电压小50毫伏(MV)。In this embodiment, the safety cutoff voltage is a cutoff voltage set when the battery enters a constant current charge, and the safe cutoff voltage is generally smaller than a safe voltage of the battery. Among them, the safe voltage of the battery is determined by the battery material of the battery. For example, depending on the material of the battery, the safe voltage of the battery can be 4.3V, 4.4V, 4.5V, and the like. It can be understood that in order to ensure the safety of constant voltage charging, the safety cut-off voltage is generally set to be less than the safe voltage of the battery. For example, the safety cut-off voltage can be 50 millivolts (MV) less than the safe voltage of the battery.
步骤105,调整所述电池的充电电流,使所述电池的实际充电功率达到预设的最大阈值。流程返回至步骤103,继续实时检测所述电池的充电电压。Step 105: Adjust a charging current of the battery, so that an actual charging power of the battery reaches a preset maximum threshold. The flow returns to step 103 to continue detecting the charging voltage of the battery in real time.
在一些实施方式中,可根据充电设备,例如适配器的输出能力、充电线路及所述电池的耐受能力来确定所述电池的充电功率的最大阈值。其中,所述电池的充电功率的最大阈值可以是根据所述电池的出厂测试数据得到的。In some embodiments, the maximum threshold for the charging power of the battery can be determined based on the charging device, such as the output capabilities of the adapter, the charging line, and the tolerance of the battery. Wherein, the maximum threshold of the charging power of the battery may be obtained according to the factory test data of the battery.
可以理解的是,在恒流充电过程中,由于充电电压逐渐增大,而所述电池的充电功率的最大阈值固定不变,为了使所述电池的实际充电功率尽可能地达到最大阈值,需要根据不断变化的充电电压来逐渐调整充电电流。图4示出了在理想状态下的电池在恒流充电过程中的充电电流与充电电压的曲线示意图。It can be understood that, in the constant current charging process, since the charging voltage is gradually increased, and the maximum threshold of the charging power of the battery is fixed, in order to make the actual charging power of the battery reach the maximum threshold as much as possible, it is required. The charging current is gradually adjusted according to the changing charging voltage. Fig. 4 is a graph showing the relationship between the charging current and the charging voltage of the battery in the ideal state under constant current charging.
步骤106,以所述安全截止电压对所述电池进行恒压充电。 Step 106, the battery is subjected to constant voltage charging with the safety cutoff voltage.

The energy that needs to be absorbed during the charging phase shortens the time of constant voltage charging, thereby shortening the total charging time and increasing the charging speed.
在一些实施方式中,所述步骤105可包括:根据所述电池的充电功率的最大阈值、所述电池的当前充电电压、以及充电电流与充电功率和充电电压之间 的对应关系,调整当前的充电电流,使所述电池的当前充电功率达到所述最大阈值。In some embodiments, the step 105 may include: adjusting a current threshold according to a maximum threshold of a charging power of the battery, a current charging voltage of the battery, and a correspondence between a charging current and a charging power and a charging voltage. The charging current is such that the current charging power of the battery reaches the maximum threshold.
具体地,在第一实施方式中,请参阅图5,所述步骤104可包括:Specifically, in the first embodiment, referring to FIG. 5, the step 104 may include:

步骤502,根据所述电池的充电功率的最大阈值、获取到的所述当前充电电压、以及充电电流与充电功率和充电电压之间的对应关系,计算所述电池的充电电流,其中,所述当前充电电压与计算出的充电电流的乘积等于所述电池的充电功率的最大阈值。Step 502: Calculate a charging current of the battery according to a maximum threshold of charging power of the battery, the obtained current charging voltage, and a correspondence between a charging current and a charging power and a charging voltage, where The product of the current charging voltage and the calculated charging current is equal to the maximum threshold of the charging power of the battery.
步骤503,根据计算出的充电电流调整电流输出装置的输出电流,使所述电池的当前充电功率达到所述最大阈值。流程返回至所述步骤501,并继续执行所述步骤501至503,直至所述电池的充电电压达到所述安全截止电压。Step 503: Adjust an output current of the current output device according to the calculated charging current, so that a current charging power of the battery reaches the maximum threshold. The flow returns to the step 501 and continues to perform the steps 501 to 503 until the charging voltage of the battery reaches the safety cutoff voltage.
可以理解的是,为了使所述电池的当前充电功率尽可能地达到所述最大阈值,应尽可能地缩短所述预设时间间隔,例如设定所述预设时间间隔为5秒,10秒,30秒,1分钟等,从而可以尽可能多地对所述电池的当前充电电压进行采样。It can be understood that, in order to make the current charging power of the battery reach the maximum threshold as much as possible, the preset time interval should be shortened as much as possible, for example, setting the preset time interval to 5 seconds, 10 seconds. , 30 seconds, 1 minute, etc., so that the current charging voltage of the battery can be sampled as much as possible.

The charging current is adjusted, and the output current of the current output device is adjusted according to the charging current that is continuously obtained, so that the current charging power of the battery reaches the maximum threshold until the charging voltage of the battery reaches the safety cut-off voltage.
可以理解的是,在所述第二实施方式中,在进入恒流充电过程的初始状态下,若从所述充电参数表中未获取到与所述当前充电电压对应的充电电流,则以预设的初始充电电流对所述电池进行恒流充电,并返回至所述步骤602,继续获取所述电池的新的当前充电电压。It can be understood that, in the second embodiment, in the initial state of entering the constant current charging process, if the charging current corresponding to the current charging voltage is not obtained from the charging parameter table, The initial charging current is applied to the battery for constant current charging, and returns to the step 602 to continue acquiring the new current charging voltage of the battery.
可以理解的是,在根据获取到的充电电流至少调整了一次所述电流输出装置的输出电流之后,若从所述充电参数表中未获取到与新的当前充电电压对应的充电电流,则继续以上一次获取到的充电电流来控制所述电流输出装置的输出电流,并返回至所述步骤602,继续获取所述电池的新的当前充电电压。It can be understood that, after the output current of the current output device is adjusted at least once according to the obtained charging current, if the charging current corresponding to the new current charging voltage is not obtained from the charging parameter table, continue The charging current obtained in the previous time controls the output current of the current output device, and returns to the step 602 to continue acquiring the new current charging voltage of the battery.
可以理解的是,在所述第二实施方式中,由于所述充电参数表记录了所述电池在恒流充电过程中的多个时刻对应的充电参数,因此,只需在充电过程中继续根据新的当前充电电压来继续调用数据,即,根据继续获取到的新的当前充电电压来从所述充电参数表中继续获取对应的充电电流,即可调整所述电流输出装置的输出电流,使所述电池的当前充电功率达到所述最大阈值。It can be understood that, in the second embodiment, since the charging parameter table records charging parameters corresponding to the battery at a plurality of times during the constant current charging process, it is only necessary to continue according to the charging process. The new current charging voltage is used to continue to call the data, that is, the corresponding charging current is continuously obtained from the charging parameter table according to the new current charging voltage that is continuously acquired, so that the output current of the current output device can be adjusted, so that The current charging power of the battery reaches the maximum threshold.
在第三实施方式中,请参阅图7,所述步骤104可包括:In the third embodiment, referring to FIG. 7, the step 104 may include:
