具体实施方式
下面详细描述本申请的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本申请,而不能理解为对本申请的限制。
需要说明的是,本申请提出的适配器适用于为待充电设备充电。在本申请的实施例中, 适配器可输出脉动波形的电压/电流为待充电设备充电。脉动波形的电压/电流的大小周期性变换,与传统的恒压恒流相比,能够降低锂电池的析锂现象,提高电池的使用寿命,并且还能够减少充电接口的触点的拉弧的概率和强度,提高充电接口的寿命,以及有利于降低电池的极化效应、提高充电速度、减少电池的发热,保证充电时的安全可靠。此外,由于适配器输出的是脉动波形的电压,从而无需在适配器中设置电解电容,不仅可以实现适配器的简单化、小型化,还可大大降低成本。
如图2所示,在一个实施例中,适配器1包括:第一整流单元101、开关单元102、变压器103、第二整流单元104、第一充电接口105、采样单元106和控制单元107。
第一整流单元101对输入的交流电(市电,例如AC220V)进行整流以输出第一脉动波形的电压例如馒头波电压,其中,第一整流单元101可以是四个二极管构成的全桥整流电路。
开关单元102用于根据控制信号对第一脉动波形的电压进行调制,其中,开关单元102可由MOS管构成,通过对MOS管进行PWM(Pulse Width Modulation,脉冲宽度调制)控制以对馒头波电压进行斩波调制。
变压器103用于根据调制后的所述第一脉动波形的电压输出第二脉动波形的电压。
第二整流单元104用于对所述第二脉动波形的电压进行整流以输出第三脉动波形的电压。在一个实施例中,第二整流单元104可由二极管或MOS管组成,能够实现次级同步整流,从而第三脉动波形与调制后的第一脉动波形保持同步,需要说明的是,第三脉动波形与调制后的第一脉动波形保持同步。具体是指第三脉动波形的相位与调制后的第一脉动波形的相位保持一致。第三脉动波形的幅值与调制后的第一脉动波形的幅值变化趋势保持一致。
第一充电接口105与第二整流单元104相连,用于将第三脉动波形的电压输出,以给待充电设备2充电。
采样单元106用于对第二整流单元104输出的电压和/或电流进行采样以获得电压采样值和/或电流采样值,控制单元107分别与采样单元106和开关单元102相连,控制单元107输出控制信号至开关单元102,并根据电压采样值和/或电流采样值对控制信号的占空比进行调节,以使该第二整流单元104输出的第三脉动波形的电压满足充电需求。
如图2所示,在一个实施例中,待充电设备2包括:第二充电接口201和电池202,第二充电接口201与电池202相连,其中,当第二充电接口201与第一充电接口105连接时,第二充电接口201将第三脉动波形的电压加载至电池202,实现对电池202的充电。在本申请的一个实施例中,适配器1还包括驱动单元,例如MOSFET驱动器,驱动单元连接在开关单元102与控制单元107之间,驱动单元用于根据控制信号驱动开关单元102的开通 或关断。当然,需要说明的是,在本申请的其他实施例中,驱动单元也可集成在控制单元107中。
在本申请的一个实施例中,适配器1还包括辅助绕组和供电单元,辅助绕组根据调制后的第一脉动波形的电压生成第四脉动波形的电压,供电单元与辅助绕组相连,供电单元(例如包括滤波稳压模块、电压转换模块等)用于对第四脉动波形的电压进行转换以输出直流电,分别给驱动单元和/或控制单元107供电。供电单元可以是由滤波小电容、稳压芯片等器件构成,实现对第四脉动波形的电压进行处理、转换,输出3.3V或5V等低电压直流电。
也就是说,驱动单元的供电电源可以由供电单元对第四脉动波形的电压转换得到,控制单元107设置在初级侧时,其供电电源也可以由供电单元对第四脉动波形的电压转换得到。其中,控制单元107设置在初级侧时,供电单元提供两路直流电输出,以分别给驱动单元和控制单元107供电,在控制单元107与采样单元106之间设置光耦隔离单元实现适配器1的初级和次级之间的信号隔离。
当控制单元107设置在初级侧且集成有驱动单元时,供电单元单独给控制单元107供电。当控制单元107设置在次级侧、驱动单元设置在初级侧时,供电单元单独给驱动单元供电,控制单元107的供电由次级提供例如通过一个供电单元将第二整流单元104输出的第三脉动波形的电压转换为直流电源来供给控制单元107。
在本申请的另一个实施例,适配器1还包括第一电压检测单元,第一电压检测单元分别与辅助绕组和控制单元107相连,第一电压检测单元用于检测第四脉动波形的电压以生成电压检测值,其中,控制单元107还用于根据电压检测值对控制信号的占空比进行调节。
也就是说,控制单元107可根据第一电压检测单元检测到的辅助绕组输出的电压来反映第二整流单元104输出的电压,然后根据电压检测值对控制信号的占空比进行调节,使得第二整流单元104的输出匹配电池的充电需求。
在本公开的实施例中,适配器1还可与待充电设备通过充电接口进行双向通信,交互终端的信息(例如,电池电压信息、电池温度信息等)。
在本公开的实施例中,待充电设备可以是指终端,该“终端”可包括,但不限于智能手机、电脑、个人数字助理(personal digital assistant,PDA)、智能穿戴设备、游戏设备、摄像设备等。适配器,还可以为车载适配器、充电宝等具有给终端充电的功能的设备。
应理解,本申请中的适配器也可以是快充适配器或普通适配器。
基于上述待充电设备的适配器,本申请提出了一种待充电设备的适配器老化检测方法和待充电设备的适配器老化检测装置。
下面结合附图来描述本申请实施例的适配器老化检测方法和适配器老化检测装置。
图1为根据本申请实施例的适配器老化检测方法的流程图。如图1所示,本申请实施例的适配器老化检测方法,包括以下步骤:
S101:获取待充电设备在预设状态下的充电曲线。
其中,预设状态可为从待充电设备电量为零充电至100%的状态。
应当理解的是,在确定适配器匹配的待充电设备之后,对待充电设备按照预设状态进行充电,以获取待充电设备在预设状态下的充电曲线,即待充电设备充电电量和时间的关系曲线。
S102:根据充电曲线生成适配器的输出曲线。
其中,输出曲线包括多个负载状态,以及每个负载状态的持续时间。
还需要说明的是,负载状态可为负载百分比,例如100%负载(即满载)、80%负载等。其中,负载百分比与待充电设备的电量相对应,例如,当待充电设备电量为0%时,相应的负载状态为100%负载,当待充电设备电量为20%时,相应的负载状态为80%,当待充电设备电量为100%时,相应的负载状态为0%负载。
其中,每个负载状态的持续时间可根据待充电设备的充电电量从一个百分比阶跃到下一百分比的持续时间。
因此,输出曲线可为满载老化15分钟,80%负载老化30分钟,50%负载老化30分钟……直至0%负载老化预设时间。
S103:控制适配器按照输出曲线进行输出,并检测适配器的温度。
需要说明的是,可通过负载模拟器控制适配器按照输出曲线进行输出。其中,负载模拟器可包括控制器、负载模拟电路和与适配器相连的接口,控制器用于根据负载曲线对负载模拟电路进行控制以生成不同负载状态,使模拟负载电路通过与适配器相连的接口,按照负载曲线对应的负载状态接收适配器传送的电能,从而实现为适配器进行模拟输出的目的。进一步地,负载模拟器还可包括显示装置,以实时显示当前负载状态,便于对当前负载状态以及每个负载状态的持续时间进行观测。
S104:根据适配器的温度判断是否老化合格。
也就是说,先确定适配器匹配的待充电设备,然后获取该待充电设备在预设状态下的充电曲线,根据充电曲线生成适配器的输出曲线,控制适配器按照输出曲线进行输出,即控制适配器的输出状态模拟为待充电设备充电的状态,同时检测适配器的温度,并根据适配器的温度判断适配器是否老化合格。
根据本申请的一个实施例,还可根据适配器的温度和/或老化检测时间生成输出曲线。
由此,通过控制适配器按照输出曲线进行输出,实现适配器输出状态的动态调整,能够在保证适配器老化效果的前提下,节约适配器的生产成本,即,适配器通过减少热处理 的方式节省成本时,也不会在老化检测过程中产生老化过度。
根据本申请的一个实施例,根据适配器的温度判断是否老化合格具体包括:在每个负载状态运行对应的持续时间之后,判断适配器的温度是否大于预设温度阈值;如果大于预设温度阈值,则判断老化。
其中,每个负载状态对应的预设温度阈值可不同。
需要说明的是,输出曲线可包括N个负载状态,其中,第i个负载状态对应的预设温度阈值小于第i+1个负载状态对应的预设温度阈值,其中,i小于N。例如,以待充电设备每充电20%为一个负载状态为例,则输出曲线的第1个负载状态可为满载状态,输出曲线的第2个负载状态可为80%负载状态,进一步地,第1负载状态对应的第一温度阈值小于第2负载状态对应的第二温度阈值。其中,第一温度阈值可为100度,第二温度阈值可为110度。
举例来说,以满载老化15分钟然后800%负载老化30分钟为例,控制适配器以第1负载状态进行输出,并持续第一预设时间例如15分钟,然后检测适配器的当前温度,判断适配器的当前温度是否大于第1负载状态对应的第一温度阈值,如果适配器的当前温度大于第1负载状态对应的第一温度阈值,则判断适配器老化不合格,标记为不良品,如果适配器的当前温度小于或等于第1负载状态对应的第一温度阈值,则判断适配器老化合格,然后控制适配器以第2负载状态进行输出,并持续第二预设时间,例如30分钟,然后检测适配器的当前温度,判断适配器的当前温度是否大于第2负载状态对应的第二温度阈值,如果适配器的当前温度大于第2负载状态对应的第二温度阈值,则判断适配器老化不合格,标记为不良品,如果适配器的当前温度小于或等于第2负载状态对应的第二温度阈值,则判断适配器老化合格。
由此,通过在每个负载状态持续时间之后对适配器的老化是否合格进行检测,能够及时检测出适配器是否合格,以及若当适配器出现大量不合格时,可根据适配器不合格节点对适配器的生产进行调整,从而提高适配器生产制造的良品率。
综上所述,根据本申请实施例的待充电设备的适配器老化检测方法,通过获取待充电设备在预设状态下的充电曲线,然后根据充电曲线生成适配器的输出曲线,控制适配器按照输出曲线进行输出,并检测适配器的温度,根据适配器的温度判断是否老化合格。由此,本申请实施例的检测方法根据输出曲线控制适配器进行输出,从而既可以满足适配器的老化效果,还可以检测出适配器工作时的工作情况,确保适配器的可靠性。
图2为根据本申请实施例的待充电设备的适配器老化检测装置的方框示意图。如图2所示,本申请实施例的待充电设备的适配器老化检测装置100包括:获取模块10、生成模块20和检测模块30。
其中,获取模块10用于获取待充电设备在预设状态的充电曲线;生成模块20用于根据充电曲线生成适配器的输出曲线;检测模块30控制适配器按照输出曲线进行输出,并检测适配器的温度,以及根据适配器的温度判断是否老化合格。
其中,预设状态为从待充电设备电量为零充电至100%的状态。
其中,输出曲线包括多个负载状态,以及每个负载状态的持续时间。
应当理解的是,在确定适配器匹配的待充电设备之后,对待充电设备按照预设状态进行充电,以获取待充电设备在预设状态下的充电曲线,即待充电设备充电电量和时间的关系曲线。
需要说明的是,负载状态可为负载百分比,例如100%负载、80%负载等。其中,负载百分比与待充电设备的电量相对应,例如,当待充电设备电量为0%时,相应的负载状态为100%负载,当待充电设备电量为20%时,相应的负载状态为80%,当待充电设备电量为100%时,相应的负载状态为0%负载。
其中,每个负载状态的持续时间可根据待充电设备的充电电量从一个百分比阶跃到下一百分比的持续时间。
因此,输出曲线可为满载老化15分钟,80%负载老化30分钟,50%负载老化30分钟……直至0%负载老化预设时间。
也就是说,先确定适配器匹配的待充电设备,然后获取该待充电设备在预设状态下的充电曲线,根据充电曲线生成适配器的输出曲线,控制适配器按照输出曲线进行输出,即控制适配器的输出状态模拟为待充电设备充电的状态,同时检测适配器的温度,并根据适配器的温度判断适配器是否老化合格。
根据本申请的一个实施例,还可根据适配器的温度和/或老化检测时间生成输出曲线。
由此,通过控制适配器按照输出曲线进行输出,实现适配器输出状态的动态调整,能够在保证适配器老化效果的前提下,节约适配器的生产成本,即,适配器通过减少热处理的方式节省成本时,也不会在老化检测过程中产生老化过度。
根据本申请的一个实施例,检测模块30还用于在每个负载状态运行对应的持续时间之后,判断适配器的温度是否大于预设温度阈值,如果大于预设温度阈值,则判断老化。
其中,每个负载状态对应的预设温度阈值可不同。
需要说明的是,输出曲线可包括N个负载状态,其中,第i个负载状态对应的预设温度阈值小于第i+1个负载状态对应的预设温度阈值,其中,i小于N。例如,以待充电设备每充电20%为一个负载状态为例,则输出曲线的第1个负载状态可为满载状态,输出曲线的第2个负载状态可为80%负载状态,进一步地,第1负载状态对应的第一温度阈值小于第2负载状态对应的第二温度阈值。其中,第一温度阈值可为100度,第二温度阈值可为 110度。
举例来说,以满载老化15分钟然后800%负载老化30分钟为例,检测模块30向适配器施加满载即第1负载状态,持续第一预设时间例如15分钟,然后检测适配器的当前温度,判断适配器的当前温度是否大于第1负载状态对应的第一温度阈值,如果适配器的当前温度大于第1负载状态对应的第一温度阈值,则判断适配器老化不合格,标记为不良品,如果适配器的当前温度小于或等于第1负载状态对应的第一温度阈值,则判断适配器老化合格,然后检测模块30继续向适配器施加80%负载即第2负载状态并持续第二预设时间,例如30分钟,然后检测适配器的当前温度,判断适配器的当前温度是否大于第2负载状态对应的第二温度阈值,如果适配器的当前温度大于第2负载状态对应的第二温度阈值,则判断适配器老化不合格,标记为不良品,如果适配器的当前温度小于或等于第2负载状态对应的第二温度阈值,则判断适配器老化合格。
由此,通过在每个负载状态之后对适配器的老化是否合格进行检测,能够及时检测出适配器是否合格,以及若当适配器出现大量不合格时,可根据适配器不合格节点对适配器的生产进行调整,从而提高适配器生产制造的良品率。
综上所述,根据本申请实施例的待充电设备的适配器老化检测装置,通过获取模块待充电设备在预设状态的充电曲线,然后生成模块根据该曲线生成适配器的输出曲线,检测模块控制适配器按照输出曲线进行输出,并检测适配器的温度,根据适配器的温度判断是否老化合格。由此,本申请实施例的检测装置根据输出曲线控制适配器进行输出,从而既可以满足适配器的老化效果,还可以检测出适配器工作时的工作情况,确保适配器的可靠性。
