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满足充电需求。
如图1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将第三脉动波形加载至电池202，实现对电池202的充电。
在本公开的一个实施例中，充电装置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，在本公开的其他实施例中，驱动单元也可集成在控制单元107中。
在本公开的一个实施例中，充电装置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充电装置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。
在本公开的另一个实施例，充电装置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。
应理解，本公开中的充电装置可以是快充充电装置，例如，采用低压大电流快充的充电装置或采用高压低电流快充的充电装置等。本公开中的充电装置还可以为普通充电装置，例如，相关技术中采用5V/1A输出的充电装置。本公开实施例对此并不做限制。
基于上述待充电设备的充电装置，本公开提出了一种电池的快速充电方法、充电装置、待充电设备和充电系统。
下面参考附图描述本公开实施例的电池的快速充电方法、充电装置、待充电设备和充电系统。
需说明的是，锂离子电池充电过程中，阴极电位持续上升，阳极电位持续降低。当阳极电位低于0V时，Li+(锂离子)会在阳极析出，形成锂枝晶，即“析锂”。析锂不仅会影响电池的电化学性能，而且会 降低电池的安全性。因此，在电池使用过程中，需要尽量避免电池析锂的情况出现。
本申请发明人通过对三电极法获得的电池充电曲线进行分析发现，在充电过程中，只要阴极电位未达到锂金属析出电位，电池的充电参数(充电电压、充电电流等)均可超出电池额定参数。例如，当电池的额定电压为4.4V、额定充电电流为3.0A时，在实际充电过程中，可以将电池的电压充电至4.4V以上，且电流也能超出额定充电电流3.0A。
应理解，电池的额定参数(例如额定充电倍率、额定电压和额定容量等)可由电池制作商规定。
由此，通过测试，可以得到电池充电时产生锂金属析出时的电压Va，也就是说，在电池的电压未达到Va时，整个充电过程电池也就未产生锂金属析出。进而，在得到电池充电时产生锂金属析出时的电压Va之后，可基于电池充电时产生锂金属析出时的电压Va，得到超过电池额定电压的电池充电电压，例如下面实施例提到的第一电压和第三电压。
本公开实施例预先设定了超过电池额定电压的电池充电电压。在实际充电过程中，可先对电池进行恒流充电，直至将电池电压充电至超过电池额定电压的电池充电电压；然后，对电池进行恒压充电。从而，突破电池额定参数的限制，较大幅度缩短充电时间，有效提升充电速度，且不会影响电池的使用寿命。
需说明的是，在本公开实施例中，在充电装置与待充电设备通过充电接口连接后，充电装置与待充电设备可进行双向通信，其中，充电装置可通过充电接口中的电源线为待充电设备的电池充电，充电装置通过充电接口中的数据线与待充电设备进行通信。
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)、可穿戴设备、蓝牙耳机、游戏设备、摄像设备等。充电装置可以是，适配器、移动电源(充电宝)或车载充电器等具有给终端充电的功能的设备。本公开实施例的电池的快速充电方法可应用于充电装置，也可应用于待充电设备。其中，在应用于充电装置时，待充电设备可采集电池的状态参数(电压、电流等)，并将该电池的状态参数通过充电接口中的数据线发送至充电装置。或者，在应用于待充电设备时，待充电设备可将充电参数(充电电压、充电电流、充电模式等)发给充电装置。
应理解，待充电设备可以包括一个电池，也可包括多个串联连接的电池。下文结合具体的例子，以第一电池和多个电池为例，分别详细描述本公开一种实施例的电池的快速充电方法。
一)待充电设备包括一个电池
图2是根据本公开实施例的电池的快速充电方法的流程图。如图2所示，方法包括：
S1：使用第一充电倍率对电池进行恒流充电，直至电池的电压达到第一电压，其中，第一电压大于电池的额定电压。
具体地，第一充电倍率和第一电压可预先设定。在使用第一充电倍率对电池进行恒流充电时，可将充电电流调整至为第一充电倍率，以对待充电设备的电池进行恒流充电。即言，在恒流充电时，可保持充电电流不变，电池电压将随充电过程的进行逐渐增加。
在本公开实施例中，第一充电倍率可小于或等于电池的额定充电倍率，例如，电池的额定充电倍率为1.5C时，第一充电倍率可为1.3C。其中，电池的充电倍率指电池的充电电流与电池的额定容量之比。
第一电压的范围可为额定电压的1.01-1.2倍，更具体地，第一电压的范围可为额定电压的1.01-1.02倍。例如，额定电压为4.4V时，第一电压可为4.45V或更高电压。并且，电池的额定电压低于(即小于)电池充电时产生锂金属析出时的电压。当然，为了确保充电过程不产生锂金属析出，第一电压也是低于电池充电时产生锂金属析出时的电压的。
需要说明的是，第一电压可通过试验测试确定，不同型号的电池可对应不同的第一电压。具体地，第一电压可以离线确定，实际交互时，直接使用通过测试确定出的第一电压即可。
应理解，第一电压可以是基于电池充电时产生锂金属析出时的电压而确定的。例如，在确定每种型号的电池的第一电压时，可以先确定电池充电时产生锂金属析出时的电压，然后基于电池充电时产生锂金属析出时的电压选取合适的第一电压，以在确保充电过程未产生锂金属析出的前提下选取岀高于额定电压的第一电压。换言之，第一电压可在高于电池额定电压的范围内选取，第一电压可选取足够高的电压值，只要满足整个充电过程未产生锂金属析出即可。
S2：对电池进行恒压充电；
具体地，以第一电压对电池进行恒压充电。
S3：获取电池的电流，当电池的电流达到预设阈值时，停止对电池充电。
具体地，在使用第一电压对电池进行恒压充电时，可将充电电压调整至为第一电压，以对待充电设备的电池进行恒压充电。即言，在恒压充电时，可保持充电电压不变，电池电流将随充电过程的进行逐渐减小。
可选地，作为一个实施例，在使用步骤S1的恒流充电方式将电池的电压充电至第一电压时，电池容量从额定容量的0％充电至较高容量，例如可充电至80％以上(包括80％)。进而，在使用步骤S2的恒压充电方式对电池进行充电时，只需将剩余容量即低于额定容量的20％充满，完成剩余的充电即可。
可以理解的是，随着恒压充电的进行，电池容量越来越高，维持第一电压所需要的电流也越来越小，直至电池的电流达到预设阈值时，充电截止，即在此时，认为电池充满电了。也就是说，在以第一电压对电池进行恒压充电时，充电电压恒定在第一电压，此时可实时获取电池的电流，直至电池电流达到预设阈值时，停止对电池充电。
由此，通过以第一电压对电池进行恒压充电，可实现大电流截止，缩短充电时间，有效提升充电速度和充电效率。应理解，上述充电参数(第一电流倍率、第一电压、预设阈值)可以存储于充电装置中，也可以存储于待充电设备中，这取决于本公开实施例的电池快速充电方法的执行主体是充电装置还是待充电设备。
例如，应用于充电装置时，可以由待充电设备负责采集电池的状态参数(本实施例中为电池电压和电池电流)，并将该电池的电压和电流通过充电接口中的数据线发送至充电装置；充电装置在与待充电设 备通过充电接口连接后，使用第一充电倍率对电池进行恒流充电，即将充电电流调整为第一充电倍率，并在恒流充电过程中通过待充电设备获取电池的电压，在电池的电压达到第一电压时，以第一电压对电池进行恒压充电，即将充电电压调整为第一电压，在恒压充电过程中通过待充电设备获取电池的电流，并在电池的电流达到预设阈值时，停止充电。又如，应用于待充电设备时，待充电设备不但负责采集电池的状态参数(本实施例中为电池电压和电池电流)，还负责经将充电参数(本实施例中为第一电流倍率、第一电压、预设阈值)发送给充电装置；待充电设备在与充电装置通过充电接口连接后，可向充电装置发送第一电流倍率和恒流充电指令，充电装置在接收到第一电流倍率和恒流充电指令之后，使用接收到第一充电倍率对电池进行恒流充电，即将充电电流调整为第一充电倍率；待充电设备在恒流充电过程中获取电池的电压，并在电池的电压达到第一电压时，向充电装置发送第一电压和恒压充电指令，充电装置以第一电压对电池进行恒压充电，即将充电电压调整为第一电压；待充电设备在恒压充电过程中获取电池的电流，并在电池的电流达到预设阈值时，停止充电。
具体地，结合图1实施例，使用第一充电倍率对电池进行恒流充电，控制单元可根据第一充电倍率和第二整流单元的输出电流对控制信号的占空比进行调节，以使该第二整流单元输出的第三脉动波形满足以使用第一充电倍率进行恒流充电需求。使用第一电压对电池进行恒压充电，控制单元可根据第一电压和第二整流单元的输出电压对控制信号的占空比进行调节，以使该第二整流单元输出的第三脉动波形满足以使用第一电压进行恒压充电需求。
由此，本公开实施例提出的电池的快速充电方法，先使用第一充电倍率对电池进行恒流充电，直至将电池的电压充电至第一电压，再以第一电压对电池进行恒压充电，直至电池的电流达到预设阈值，从而，能够将电池电压充电至比额定电压更高的电压，突破电池额定参数的限制，较大幅度缩短充电时间，有效提升充电速度，且不会影响电池的使用寿命。
二)待充电设备包括多个电池
图3是根据本公开实施例的电池的快速充电方法的流程图。如图3所示，方法包括：
S11：使用第一充电倍率对多个电池进行恒流充电，直至任一电池的电压达到第一电压，其中，第一电压大于至少一个每个电池的额定电压中的最小额定电压。
具体地，多个电池可串联连接。第一充电倍率和第一电压可预先设定。在使用第一充电倍率对多个电池进行恒流充电时，可将充电电流调整至为第一充电倍率，以对待充电设备的多个电池进行恒流充电。即言，在恒流充电时，可保持充电电流不变，每个电池电压将随充电过程的进行逐渐增加。
并且，在多个电池进行恒流充电，可监测每个电池的电压，并根据每个电池的电压对多个电池进行均衡控制，以使多个电池的电池基本保持一致。由此，对多个电池进行恒流充电，直至任一电池的电压达到第一电压。
在本公开实施例中，第一充电倍率可小于或等于每个电池的额定充电倍率。应理解，多个电池的额定参数例如额定充电倍率、额定电压可相同，也可不相同。例如，额定充电倍率相同时，假设每个电池 的额定充电倍率均为1.5C，则第一充电倍率可选择1.3C。又如，额定充电倍率不相同时，假设多个电池的额定充电倍率的最小值为1.5C，则第一充电倍率可选择1.3C。
第一电压的范围可为最小额定电压的1.01-1.2倍。应理解，不同电池可具有相同的额定电压或不同的额定电压。例如，每个电池的额定电压均为4.4V时，第一电压均可为4.4V的1.01-1.2倍，例如可以为4.45V或更高电压。又如，多个电池包括两个电池，其中第一电池的额定电压为4.4V，第二电池的额定电压为4.2V时，第一电压可为4.25V或更高电压。
并且，电池的额定电压低于(即小于)电池充电时产生锂金属析出时的电压。当然，为了确保充电过程不产生锂金属析出，第一电压也是低于每个电池充电时产生锂金属析出时的电压的。
需要说明的是，第一电压可通过试验测试确定。具体地，第一电压可以离线确定，实际交互时，直接使用通过测试确定出的第一电压即可。
应理解，第一电压可以是基于每个电池充电时产生锂金属析出时的电压而确定的。例如，在确定第一电压时，可以先确定每个电池充电时产生锂金属析出时的电压，然后基于每个电池充电时产生锂金属析出时的电压选取合适的第一电压，以在确保充电过程未产生锂金属析出的前提下，选取岀高于每个电池的额定电压的第一电压。换言之，第一电压可在高于每个电池额定电压的范围内选取，第一电压可选取足够高的电压值，只要满足整个充电过程未产生锂金属析出即可。
S12：对多个电池进行恒压充电；具体地，以多个第一电压之和对多个电池进行恒压充电。
S13：获取每个电池的电流，当任一电池的电流达到相应的预设阈值时，停止对相应电池充电。
具体而言，以N(N为大于1的整数)个电池为例，可以N个第一电压之和即V1×N对N个电池进行恒压充电。在恒压充电的过程中，可监测每个电池的电压，并根据每个电池的电压对多个电池进行电压均衡控制，以使多个电池的电池基本保持一致。
并且，N个电池分别与N个预设阈值对应，在恒压充电的过程中，对每个电池的电流进行监测，当第i个电池的电流达到第i个电池的预设阈值时，停止对第i个电池充电，i大于等于1且小于等于N。例如，可通过开关将第i个电池断开，以停止对第i个电池充电。
进一步地，在停止对第i个电池充电之后，还可将N个第一电压之和调整为(N-1)个第一电压之和，此时，以(N-1)个第一电压之和对N个电池进行恒压充电，并继续对剩余的(N-1)个电池进行电压均衡控制，同时监控剩余的(N-1)个电池的电流，当第j个电池的电流达到第j个电池的预设阈值时，停止对第j个电池充电，j≠i，j大于等于1且小于等于N。
如此重复，直至N个电池的电流均达到相应的预设阈值，完成整个充电过程。
具体地，在使用多个第一电压之和对多个电池进行恒压充电时，可将充电电压调整至为多个第一电压之和，以对待充电设备的多个电池进行恒压充电。即言，在恒压充电时，可保持充电电压不变，电池电流将随充电过程的进行逐渐减小。
可选地，作为一个实施例，在使用步骤S11的恒流充电方式将任一电池的电压充电至第一电压时， 任一电池容量从额定容量的0％充电至较高容量，例如可充电至80％以上(包括80％)。进而，在使用步骤S12的恒压充电方式对电池进行充电时，将每个电池的剩余容量充满，完成剩余的充电即可。
可以理解的是，随着恒压充电的进行，电池容量越来越高，维持第一电压所需要的电流也越来越小，直至电池的电流达到预设阈值时，充电截止，即在此时，认为电池充满电了。也就是说，在以多个第一电压之和对电池进行恒压充电时，充电电压恒定在多个第一电压之和，此时可实时获取每个电池的电流，并在每个电池的电流达到相应的预设阈值时，停止对相应的电池充电。
由此，通过以多个第一电压之和对多个电池进行恒压充电，可实现大电流截止，缩短充电时间，有效提升充电速度和充电效率。
应理解，上述充电参数(第一电流倍率、第一电压、预设阈值)可以存储于充电装置中，也可以存储于待充电设备中，这取决于本公开实施例的电池快速充电方法的执行主体是充电装置还是待充电设备。
例如，应用于充电装置时，可以由待充电设备负责采集电池的状态参数(本实施例中为电池电压和电池电流)，并将该电池的电压和电流通过充电接口中的数据线发送至充电装置；充电装置在与待充电设备通过充电接口连接后，使用第一充电倍率对电池进行恒流充电，即将充电电流调整为第一充电倍率，并在恒流充电过程中通过待充电设备获取每个电池的电压，在任一电池的电压达到第一电压时，以多个第一电压之和对多个电池进行恒压充电，即将充电电压调整为多个第一电压之和，在恒压充电过程中通过待充电设备获取每个电池的电流，并在每个电池的电流达到相应的预设阈值时，停止对相应电池充电。
又如，应用于待充电设备时，待充电设备不但负责采集电池的状态参数(本实施例中为电池电压和电池电流)，还负责经将充电参数(本实施例中为第一电流倍率、第一电压、预设阈值)发送给充电装置；待充电设备在与充电装置通过充电接口连接后，可向充电装置发送第一电流倍率和恒流充电指令，充电装置在接收到第一电流倍率和恒流充电指令之后，使用接收到第一充电倍率对多个电池进行恒流充电，即将充电电流调整为第一充电倍率；待充电设备在恒流充电过程中获取多个电池的电压，并在任一电池的电压达到第一电压时，向充电装置发送多个第一电压之和以及恒压充电指令，充电装置以多个第一电压之和对多个电池进行恒压充电，即将充电电压调整为多个第一电压之和；待充电设备在恒压充电过程中获取每个电池的电流，并在每个电池的电流达到预设阈值时，停止对相应电池充电。
具体地，结合图1实施例，使用第一充电倍率对多个电池进行恒流充电，控制单元可根据第一充电倍率和第二整流单元的输出电流对控制信号的占空比进行调节，以使该第二整流单元输出的第三脉动波形满足以使用第一充电倍率进行恒流充电需求。使用多个第一电压之和对多个电池进行恒压充电，控制单元可根据多个第一电压之和以及第二整流单元的输出电压对控制信号的占空比进行调节，以使该第二整流单元输出的第三脉动波形满足以使用多个第一电压之和进行恒压充电需求。
由此，本公开实施例提出的电池的快速充电方法，先使用第一充电倍率对多个电池进行恒流充电，直至将任一电池的电压充电至第一电压，再以多个第一电压之和对多个电池进行恒压充电，直至每个电池的电流达到相应的预设阈值，从而，能够将电池电压充电至比额定电压更高的电压，突破电池额定参 数的限制，较大幅度缩短充电时间，有效提升充电速度，且不会影响电池的使用寿命。
下面结合图4至图5，详细描述根据本公开实施例的充电装置和待充电设备。需要说明的是，前述对电池的快速充电方法实施例的解释说明也适用于充电装置和待充电设备，此处不再赘述。
图4是根据本公开实施例的充电装置的方框示意图。其中，充电装置在与待充电设备通过充电接口连接后与待充电设备进行通信，如图4所示，充电装置10包括第一通信控制电路11和第一充电电路12。
其中，第一通信控制电路11用于使用第一充电倍率，通过第一充电电路12对至少一个电池进行恒流充电，直至任一电池的电压达到第一电压，其中，第一通信控制电路11通过待充电设备获取每个电池的电压，第一电压大于至少一个电池的额定电压中的最小额定电压；第一通信控制电路11用于通过第一充电电路12对至少一个电池进行恒压充电，并获取每个电池的电流，当任一电池的电流达到相应的预设阈值时，停止对相应电池充电，其中，第一通信控制电路11通过待充电设备获取每个电池的电流。
其中，至少一个电池串联连接，第一通信控制电路11用于以至少一个第一电压之和，通过第一充电电路12对至少一个电池进行恒压充电。
应理解，本实施例的待充电设备对单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如，结合图1实施例的充电装置时，第一充电电路12可包括第一整流单元101、开关单元102、变压器103、第二整流单元104、第一充电接口105中电源线。第一通信控制电路11可包括采样单元106和控制单元107以及第一充电接口105中通信线。

应理解，待充电设备可以包括一个电池，也可包括多个串联连接的电池。下文结合具体的例子，以第一电池和多个电池为例，分别详细描述本公开另一种实施例的电池的快速充电方法。
一)待充电设备包括一个电池
图7是根据本公开实施例的电池的快速充电方法的流程图。如图7所示，方法包括：
S10：使用第二充电倍率对电池进行恒流充电，直至电池的电压达到第二电压；
S20：使用第三充电倍率对电池进行恒流充电，直至电池的电压达到第三电压，其中，第三充电倍率小于第二充电倍率，第三电压大于第二电压，且第三电压大于电池的额定电压；
具体地，第二充电倍率和第二电压可预先设定。在使用第二充电倍率对电池进行恒流充电时，可将充电电流调整至为第二充电倍率，以对待充电设备的电池进行恒流充电。并且，第三充电倍率和第三电压可预先设定。在使用第三充电倍率对电池进行恒流充电时，可将充电电流调整至为第三充电倍率，以对待充电设备的电池进行恒流充电。在恒流充电时，可保持充电电流不变，电池电压将随充电过程的进行逐渐增加。
在本公开实施例中，第二充电倍率可为电池的额定充电倍率，第三充电倍率小于电池的额定充电倍率。例如，电池的额定充电倍率为1.5C，第三充电倍率可为1.0C。
第二电压可为电池的额定电压，第三电压的范围为额定电压的1.01-1.2倍。例如，额定电压为4.4V时，第三电压可为4.45V或更高电压。电池的额定电压低于(即小于)电池充电时产生锂金属析出时的电压。当然，为了确保充电过程不产生锂金属析出，第三电压也是低于电池充电时产生锂金属析出时的电压的。
需要说明的是，第三电压可通过试验测试确定，不同型号的电池可对应不同的第三电压。具体地，第三电压可以离线确定，实际交互时，直接使用通过测试确定出的第三电压即可。
应理解，第三电压可以是基于电池充电时产生锂金属析出时的电压而确定的。例如，在确定每种型号的电池的第三电压时，可以先确定电池充电时产生锂金属析出时的电压，然后基于电池充电时产生锂金属析出时的电压选取合适的第三电压，以在确保充电过程未产生锂金属析出的前提下选取岀高于额定电压的第三电压。换言之，第三电压可在高于电池额定电压的范围内选取，第三电压可选取足够高的电压值，只要满足整个充电过程未产生锂金属析出即可。
在本实施例中，先使用电池的额定充电倍率对电池进行恒流充电，直至电池电压充电至电池的额定电压，在电池电压充电至电池的额定电压，再使用低于电池的额定充电倍率的第三充电倍率对电池进行恒流充电，直至电池电压充电至高于额定电压的第三电压，从而能够进一步提升充电速度和充电效率，同时更准确地将电池电压控制在第三电压，确保整个充电过程未产生锂金属析出。

具体地，在使用第三电压对电池进行恒压充电时，可将充电电压调整至为第三电压，以对待充电设备的电池进行恒压充电。即言，在恒压充电时，可保持充电电压不变，电池电流将随充电过程的进行逐渐减小。
可选地，作为一个实施例，在使用步骤S10-S20的恒流充电方式，最终将电池的电压充电至第三电压时，电池容量从额定容量的0％充电至较高容量，例如可充电至80％以上(包括80％)。进而，在使用步骤S30的恒压充电方式对电池进行充电时，只需将剩余容量即低于额定容量的20％充满，完成剩余的充电即可。
可以理解的是，随着恒压充电的进行，电池容量越来越高，维持第三电压所需要的电流也越来越小，直至电池的电流达到预设阈值时，充电截止，即在此时，认为电池充满电了。也就是说，在以第三电压对电池进行恒压充电时，充电电压恒定在第三电压，此时可实时获取电池的电流，直至电池电流达到预设阈值时，停止对电池充电。
由此，通过以第三电压对电池进行恒压充电，可实现大电流截止，缩短充电时间，有效提升充电速 度和充电效率。
应理解，上述充电参数(第二电流倍率、第三电流倍率、第二电压、第三电压、预设阈值)可以存储于充电装置中，也可以存储于待充电设备中，这取决于本公开实施例的电池快速充电方法的执行主体是充电装置还是待充电设备。
例如，应用于充电装置时，可以由待充电设备负责采集电池的状态参数(本实施例中为电池电压和电池电流)，并将该电池的电压和电流通过充电接口中的数据线发送至充电装置；充电装置在与待充电设备通过充电接口连接后，使用第二充电倍率对电池进行恒流充电，即将充电电路调整为第二充电倍率，并在恒流充电过程中通过待充电设备获取电池的电压，在电池的电压达到第二电压时，使用第三充电倍率对电池进行恒流充电，即将充电电流调整为第三充电倍率，并在恒流充电过程中通过待充电设备获取电池的电压，在电池的电压达到第三电压，以第三电压对电池进行恒压充电，即将充电电压调整为第三电压，在恒压充电过程中通过待充电设备获取电池的电流，并在电池的电流达到预设阈值时，停止充电。
又如，应用于待充电设备时，待充电设备不但负责采集电池的状态参数(本实施例中为电池电压和电池电流)，还负责经将充电参数(本实施例中为第二电流倍率、第三电流倍率、第二电压、第三电压、预设阈值)发送给充电装置；待充电设备在与充电装置通过充电接口连接后，可向充电装置发送第二电流倍率和恒流充电指令，充电装置在接收到第二电流倍率和恒流充电指令之后，使用接收到第二充电倍率对电池进行恒流充电，即将充电电流调整为第二充电倍率；待充电设备在恒流充电过程中获取电池的电压，并在电池的电压达到第二电压时，向充电装置发送第三电流倍率和恒流充电指令，充电装置在接收到第三电流倍率和恒流充电指令之后，使用接收到第三充电倍率对电池进行恒流充电，即将充电电路调整为第三充电倍率；待充电设备在恒流充电过程中获取电池的电压，并在电池的电压达到第三电压时，向充电装置发送第三电压和恒压充电指令，充电装置以第三电压对电池进行恒压充电，即将充电电压调整为第三电压；待充电设备在恒压充电过程中获取电池的电流，并在电池的电流达到预设阈值时，停止充电。
具体地，结合图1实施例，使用第二充电倍率对电池进行恒流充电，控制单元可根据第二充电倍率和第二整流单元的输出电流对控制信号的占空比进行调节，以使该第二整流单元输出的第三脉动波形满足以使用第二充电倍率进行恒流充电需求。同理，使用第三充电倍率对电池进行恒流充电，控制单元可根据第三充电倍率和第二整流单元的输出电流对控制信号的占空比进行调节，以使该第二整流单元输出的第三脉动波形满足以使用第三充电倍率进行恒流充电需求。使用第三电压对电池进行恒压充电，控制单元可根据第三电压和第二整流单元的输出电压对控制信号的占空比进行调节，以使该第二整流单元输出的第三脉动波形满足以使用第三电压进行恒压充电需求。
由此，本公开实施例提出的电池的快速充电方法，先使用第二充电倍率对电池进行恒流充电，直至电池的电压达到第二电压，再使用第三充电倍率对电池进行恒流充电，直至电池的电压达到更高的第三电压，最后以第三电压对电池进行恒压充电，直至电池的电流达到预设阈值时，停止对电池充电，从而，能够将电池电压充电至比额定电压更高的电压，突破电池额定参数的限制，较大幅度缩短充电时间，有效提升充电速度，且不会影响电池的使用寿命。
二)待充电设备包括多个电池
图8是根据本公开实施例的电池的快速充电方法的流程图。如图8所示，方法包括：
S21：使用第二充电倍率对多个电池进行恒流充电，直至任一电池的电压达到第二电压。
其中，多个电池串联连接
S22：使用第三充电倍率对多个电池进行恒流充电，直至任一电池的电压达到第三电压，其中，第三充电倍率小于所述第二充电倍率，第三电压大于第二电压，且第三电压大于多个电池的额定电压中的最小额定电压。
具体地，第二充电倍率和第二电压可预先设定。在使用第二充电倍率对多个电池进行恒流充电时，可将充电电流调整至为第二充电倍率，以对待充电设备的多个电池进行恒流充电。并且，第三充电倍率和第三电压可预先设定。在使用第三充电倍率对多个电池进行恒流充电时，可将充电电流调整至为第三充电倍率，以对待充电设备的多个电池进行恒流充电。在恒流充电时，可保持充电电流不变，电池电压 将随充电过程的进行逐渐增加。
并且，在多个电池进行恒流充电，可监测每个电池的电压，并根据每个电池的电压对多个电池进行均衡控制，以使多个电池的电池基本保持一致。由此，对多个电池进行恒流充电，直至任一电池的电压达到第二电压或第二电压。
在本公开实施例中，第二充电倍率为至少一个电池的额定充电倍率中的最小额定充电倍率，第三充电倍率小于最小额定充电倍率。应理解，多个电池的额定参数例如额定充电倍率、额定电压可相同，也可不相同。例如，额定充电倍率相同时，假设每个电池的额定充电倍率均为1.5C，则第二充电倍率可为1.5C，第三充电倍率可为1.0C。又如，额定充电倍率不相同时，假设多个电池的额定充电倍率的最小值为1.5C，则第二充电倍率可为1.5C，第三充电倍率可为1.0C。
第二电压为最小额定电压，第三电压的范围为最小额定电压的1.01-1.2倍。应理解，不同电池可具有相同的额定电压或不同的额定电压。例如，每个电池的额定电压均为4.4V时，第三电压均可为4.4V的1.01-1.2倍，例如可以为4.45V或更高电压。又如，多个电池包括两个电池，其中第一电池的额定电压为4.4V，第二电池的额定电压为4.2V时，第三电压可为4.25V或更高电压。
并且，电池的额定电压低于(即小于)电池充电时产生锂金属析出时的电压。当然，为了确保充电过程不产生锂金属析出，第三电压也是低于每个电池充电时产生锂金属析出时的电压的。
需要说明的是，第三电压可通过试验测试确定。具体地，第三电压可以离线确定，实际交互时，直接使用通过测试确定出的第三电压即可。
应理解，第三电压可以是基于每个电池充电时产生锂金属析出时的电压而确定的。例如，在确定第三电压时，可以先确定每个电池充电时产生锂金属析出时的电压，然后基于每个电池充电时产生锂金属析出时的电压选取合适的第三电压，以在确保充电过程未产生锂金属析出的前提下，选取岀高于每个电池的额定电压的第三电压。换言之，第三电压可在高于每个电池额定电压的范围内选取，第三电压可选取足够高的电压值，只要满足整个充电过程未产生锂金属析出即可。
在本实施例中，先使用多个电池的最小额定充电倍率对多个电池进行恒流充电，直至电池电压充电至最小额定电压，在电池电压充电至最小额定电压，再使用低于最小额定充电倍率的第三充电倍率对多个电池进行恒流充电，直至电池电压充电至高于最小额定电压的第三电压，从而能够进一步提升充电速度和充电效率，同时更准确地将电池电压控制在第三电压，确保整个充电过程未产生锂金属析出。
S23：对多个电池进行恒压充电；
具体地，以多个第三电压之和对多个电池进行恒压充电。
S24：获取每个电池的电流，当任一电池的电流达到相应的预设阈值时，停止对相应电池充电。
具体而言，以N(N为大于1的整数)个电池为例，可以N个第三电压V3之和即V3×N对N个电池进行恒压充电。在恒压充电的过程中，可监测每个电池的电压，并根据每个电池的电压对多个电池进行电压均衡控制，以使多个电池的电池基本保持一致。
并且，N个电池分别与N个预设阈值对应，在恒压充电的过程中，对每个电池的电流进行监测，当第i个电池的电流达到第i个电池的预设阈值时，停止对第i个电池充电，i大于等于1且小于等于N。例如，可通过开关将第i个电池断开，以停止对第i个电池充电。
进一步地，在停止对第i个电池充电之后，还可将N个第三电压之和调整为(N-1)个第三电压之和，此时，以(N-1)个第三电压之和对N个电池进行恒压充电，并继续对剩余的(N-1)个电池进行电压均衡控制，同时监控剩余的(N-1)个电池的电流，当第j个电池的电流达到第j个电池的预设阈值时，停止对第j个电池充电，j≠i，j大于等于1且小于等于N。
如此重复，直至N个电池的电流均达到相应的预设阈值，完成整个充电过程。
具体地，在使用多个第三电压之和对多个电池进行恒压充电时，可将充电电压调整至为多个第三电压之和，以对待充电设备的多个电池进行恒压充电。即言，在恒压充电时，可保持充电电压不变，电池电流将随充电过程的进行逐渐减小。
可选地，作为一个实施例，在使用步骤S11的恒流充电方式将任一电池的电压充电至第三电压时，任一电池容量从额定容量的0％充电至较高容量，例如可充电至80％以上(包括80％)。进而，在使用步 骤S21的恒压充电方式对电池进行充电时，将每个电池的剩余容量充满，完成剩余的充电即可。
可以理解的是，随着恒压充电的进行，电池容量越来越高，维持第三电压所需要的电流也越来越小，直至电池的电流达到预设阈值时，充电截止，即在此时，认为电池充满电了。也就是说，在以多个第三电压之和对电池进行恒压充电时，充电电压恒定在多个第三电压之和，此时可实时获取每个电池的电流，并在每个电池的电流达到相应的预设阈值时，停止对相应的电池充电。
由此，通过以多个第三电压之和对多个电池进行恒压充电，可实现大电流截止，缩短充电时间，有效提升充电速度和充电效率。
应理解，上述充电参数(第二电流倍率、第三电流倍率、第二电压、第三电压、预设阈值)可以存储于充电装置中，也可以存储于待充电设备中，这取决于本公开实施例的电池快速充电方法的执行主体是充电装置还是待充电设备。
例如，应用于充电装置时，可以由待充电设备负责采集电池的状态参数(本实施例中为电池电压和电池电流)，并将该电池的电压和电流通过充电接口中的数据线发送至充电装置；充电装置在与待充电设备通过充电接口连接后，使用第二充电倍率对电池进行恒流充电，即将充电电路调整为第二充电倍率，并在恒流充电过程中通过待充电设备获取每个电池的电压，在任一电池的电压达到第二电压时，使用第三充电倍率对多个电池进行恒流充电，即将充电电流调整为第三充电倍率，并在恒流充电过程中通过待充电设备获取每个电池的电压，在任一电池的电压达到第三电压，以多个第三电压之和对电池进行恒压充电，即将充电电压调整为多个第三电压之和，在恒压充电过程中通过待充电设备获取每个电池的电流，并在每个电池的电流达到相应的预设阈值时，停止对相应电池充电。
又如，应用于待充电设备时，待充电设备不但负责采集电池的状态参数(本实施例中为电池电压和电池电流)，还负责经将充电参数(本实施例中为第二电流倍率、第三电流倍率、第二电压、第三电压、预设阈值)发送给充电装置；待充电设备在与充电装置通过充电接口连接后，可向充电装置发送第二电流倍率和恒流充电指令，充电装置在接收到第二电流倍率和恒流充电指令之后，使用接收到第二充电倍率对多个电池进行恒流充电，即将充电电流调整为第二充电倍率；待充电设备在恒流充电过程中获取每个电池的电压，并在任一电池的电压达到第二电压时，向充电装置发送第三电流倍率和恒流充电指令，充电装置在接收到第三电流倍率和恒流充电指令之后，使用接收到第三充电倍率对多个电池进行恒流充电，即将充电电路调整为第三充电倍率；待充电设备在恒流充电过程中获取每个电池的电压，并在任一电池的电压达到第三电压时，向充电装置发送多个第三电压之和以及恒压充电指令，充电装置以多个第三电压之和对多个电池进行恒压充电，即将充电电压调整为多个第三电压之和；待充电设备在恒压充电过程中获取每个电池的电流，并在每个电池的电流达到相应的预设阈值时，停止对相应的电池充电。
具体地，结合图1实施例，使用第一充电倍率对多个电池进行恒流充电，控制单元可根据第一充电倍率和第二整流单元的输出电流对控制信号的占空比进行调节，以使该第二整流单元输出的第三脉动波形满足以使用第一充电倍率进行恒流充电需求。使用多个第三电压之和对多个电池进行恒压充电，控制单元可根据多个第三电压之和以及第二整流单元的输出电压对控制信号的占空比进行调节，以使该第二整流单元输出的第三脉动波形满足以使用多个第三电压之和进行恒压充电需求。
由此，本公开实施例提出的电池的快速充电方法，先使用第二充电倍率对多个电池进行恒流充电，直至任一电池的电压达到第二电压，再使用第三充电倍率对多个电池进行恒流充电，直至任一电池的电压达到更高的第三电压，最后以第三电压对多个电池进行恒压充电，直至每个电池的电流达到相应的预设阈值时，停止对相应电池充电，从而，能够将电池电压充电至比额定电压更高的电压，突破电池额定参数的限制，较大幅度缩短充电时间，有效提升充电速度，且不会影响电池的使用寿命。
