Description

用于终端的充电系统、充电方法及电源适配器、充电装置 技术领域
本发明涉及终端设备技术领域，特别涉及一种用于终端的充电系统、一种用于终端的充电方法以及一种电源适配器、一种充电装置、一种充电方法。
背景技术
目前，移动终端(例如智能手机)越来越受到消费者的青睐，但是移动终端耗电量大，需要经常充电。
通常移动终端是通过电源适配器来进行充电。其中，电源适配器一般包括初级整流电路、初级滤波电路、变压器、次级整流电路、次级滤波电路以及控制电路等，这样电源适配器通过将输入的220V交流电转换为适于移动终端需求的稳定低压直流电(例如5V)，以提供给移动终端的电源管理装置和电池，实现移动终端的充电。
但是，随着电源适配器的功率变大，例如从5W向10W、15W、25W等更大功率升级时，需要更多能够承受高功率和实现更好精度控制的电子元器件进行适配，这不仅会增加电源适配器的体积，同时也会增加适配器的生产成本和制造难度。
发明内容
本申请是基于发明人对以下问题的认识和研究而做出的：
发明人在研究时发现，随着电源适配器的功率变大，电源适配器在对移动终端的电池进行充电时，容易造成电池极化电阻变大、电池温升较高，从而降低电池的使用寿命，影响电池的可靠性和安全性。
并且，通常交流电源供电时，大多数设备都无法直接使用交流电工作，这是因为交流 电例如50Hz的220V市电是间断性地输出电能，而为了不“间断”，需要使用电解电容器储能，从而当供电处于波谷时，供电的持续依赖电解电容器的储能来维持稳定的电能供应。所以，交流电源通过电源适配器给移动终端充电时，都是先将交流电源提供的交流电例如220V的交流电转换为稳定的直流电以供给移动终端。然而电源适配器是为移动终端的电池充电，从而间接为移动终端供电，供电的持续性有电池作为保障，这样电源适配器在给电池充电时就可以不需要连续输出稳定的直流电。
为此，本发明的第一个目的在于提出一种用于终端的充电系统，能够使得电源适配器输出满足充电需求的第二交流电，并使其直接加载至终端的电池，从而可以实现电源适配器的小型化、低成本，提高电池的使用寿命。
本发明的第二个目的在于提出一种电源适配器。本发明的第三个目的在于提出一种充电装置。本发明的第四个目的在于提出一种充电方法。本发明的第五个目的在于提出一种用于终端的充电方法。

其中，需要说明的是，第二交流电满足充电需求，是指第二交流电的峰值电压/平均电压和峰值电流/平均电流需满足电池充电时的充电电压和充电电流。也就是说，控制单元107根据采样到的电源适配器输出的电压和/或电流即第二交流电的电压和/或电流来调节控制信号例如PWM信号的占空比，实时地调整合成单元的输出，实现闭环调节控制，从而使得第二交流电满足终端的充电需求，保证电池安全可靠地充电，具体通过PWM信号的占空比来调节输出到电池的充电电压波形如图3所示。
可以理解的是，在对PWM信号的占空比进行调节时，可根据电压采样值、也可根据电流采样值、或者根据电压采样值和电流采样值来生成调节指令。
因此，在本发明的实施例中，通过控制开关单元102，直接对全桥整流后的第一脉动波形的电压即馒头波电压进行PWM斩波调制，送到高频变压器，通过高频变压器从初级耦合到次级，然后经过合成单元的波形合成或拼接输出交流波形的第二交流电，直接输送到电池，实现对电池的快速充电。其中，第二交流电的电压幅值，可通过PWM信号的占空比进行调节，实现电源适配器的输出满足电池的充电需求。由此可知，本发明实施例的电源适配器，取消初级、次级的电解电容器，通过交流波形的电压直接对电池充电，从而可以减小电源适配器的体积，实现电源适配器的小型化，并可大大降低成本。
其中，在本发明的一个具体示例中，控制单元107可以为MCU(Micro Controller Unit，微控制处理器)，即可以是集成有开关驱动控制功能、电压电流调节控制功能的微处理器。
根据本发明的一个实施例，控制单元107还用于根据电压采样值和/或电流采样值对控制信号的频率进行调节，即可控制输出至开关单元102的PWM信号持续输出一段时间后再停止输出，停止预定时间后再次开启PWM信号的输出，这样使得加载至电池的电压是断续的，实现电池断续充电，从而可避免电池连续充电时发热严重而导致的安全隐患，提高了电池充电可靠性和安全性。
对于锂电池而言，在低温条件下，由于锂电池自身离子和电子导电能力的下降，充电过程中容易引起极化程度的加剧，持续充电的方式会使得这种极化表现的愈加明显，同时也增加了析锂形成的可能性，从而影响电池的安全性能。并且，持续的充电会引起由于充电而形成热的不断积累，造成电池内部温度的不断上升，当温度超过一定限值时，会使得电池性能的发挥受到限制，同时增加了安全隐患。
而在本发明的实施例中，通过对控制信号的频率进行调节，使得电源适配器间断性输出，即相当于在电池充电的过程中引入电池静置过程，能够缓解持续充电中可能由极化引起的析锂现象，并且减弱生成热的持续积累的影响，达到降温的效果，保证电池充电的可靠和安全。
其中，输出至开关单元102的控制信号可如图4所示，先持续一段时间输出PWM信号，然后停止输出一段时间，再持续一段时间输出PWM信号，实现输出至开关单元102的控制信号是间隔的，并且频率可调。
如图2所示，控制单元107与第一充电接口105相连，控制单元107还用于通过第一充电接口105与终端2进行通信以获取终端2的状态信息。这样，控制单元107还用于根据终端的状态信息、电压采样值和/或电流采样值对控制信号例如PWM信号的占空比进行 调节。
其中，终端的状态信息可包括所述电池的电量、所述电池的温度、所述终端的电池电压/电流、所述终端的接口信息、所述终端的通路阻抗的信息等。
具体而言，第一充电接口105包括：电源线和数据线，电源线用于为电池充电，数据线用于与终端进行通信。当第二充电接口201与第一充电接口105连接时，电源适配器1与终端2之间可相互发送通信询问指令，并在接收到相应的应答指令后，电源适配器1与终端2之间建立通信连接，控制单元107可以获取到终端2的状态信息，从而与终端2协商充电模式和充电参数(如充电电流、充电电压)，并对充电过程进行控制。
其中，电源适配器和/或终端支持的充电模式可以包括普通充电模式和快速充电模式。快速充电模式的充电速度大于普通充电模式的充电速度(例如，快速充电模式的充电电流大于普通充电模式的充电电流)。一般而言，普通充电模式可以理解为额定输出电压为5V，额定输出电流小于等于2.5A的充电模式，此外，在普通充电模式下，电源适配器输出端口数据线中的D+和D-可以短路。而本发明实施例中的快速充电模式则不同，本发明实施例的快速充电模式下电源适配器可以利用数据线中的D+和D-与终端进行通信以实现数据交换，即电源适配器与终端之间可相互发送快速充电指令：电源适配器向终端发送快速充电询问指令，在接收到终端的快速充电应答指令后，根据终端的应答指令，电源适配器获取到终端的状态信息，开启快速充电模式，快速充电模式下的充电电流可以大于2.5A，例如，可以达到4.5A，甚至更大。但本发明实施例对普通充电模式不作具体限定，只要电源适配器支持两种充电模式，其中一种充电模式的充电速度(或电流)大于另一种充电模式的充电速度，则充电速度较慢的充电模式就可以理解为普通充电模式。相对充电功率而言，快速充电模式下的充电功率可大于等于15W。
即言，控制单元107通过第一充电接口105与终端2进行通信以确定充电模式，其中， 充电模式包括快速充电模式和普通充电模式。
具体地说，所述电源适配器与终端通过通用串行总线(Universal Serial Bus，USB)接口相连，该USB接口可以是普通的USB接口，也可以是micro USB接口。USB接口中的数据线即第一充电接口中的数据线用于所述电源适配器和所述终端进行双向通信，该数据线可以是USB接口中的D+线和/或D-线，所谓双向通信可以指电源适配器和终端双方进行信息的交互。
其中，所述电源适配器通过所述USB接口中的数据线与所述终端进行双向通信，以确定使用所述快速充电模式为所述终端充电。
需要说明的是，在电源适配器与终端协商是否采用快速充电模式为所述终端充电的过程中，电源适配器可以仅与终端保持连接状态，不充电，也可以采用普通充电模式为终端充电，还可以采用小电流为终端充电，本发明实施例对此不作具体限定。
所述电源适配器将充电电流调整至所述快速充电模式对应的充电电流，为所述终端充电。电源适配器确定采用快速充电模式为终端充电之后，可以直接将充电电流调整至快速充电模式对应的充电电流，也可以与终端协商快速充电模式的充电电流，例如，根据终端中的电池的当前电量来确定快速充电模式对应的充电电流。
在本发明实施例中，电源适配器并非盲目地增大输出电流进行快速充电，而是需要与终端进行双向通信，协商是否可以采用快速充电模式，与现有技术相比，提升了快速充电过程的安全性。

可选地，作为一个实施例，在确定所述第一充电接口与所述第二充电接口之间是否接触不良之前，所述控制单元还用于从所述终端接收用于指示所述终端的通路阻抗的信息，其中，所述控制单元向所述终端发送第四指令，所述第四指令用于询问所述终端内的电池的电压；所述控制单元接收所述终端发送的所述第四指令的回复指令，所述第四指令的回复指令用于指示所述终端内的电池的电压；所述控制单元根据所述电源适配器的输出电压和所述电池的电压，确定所述电源适配器到所述电池的通路阻抗；所述控制单元根据所述电源适配器到所述电池的通路阻抗、所述终端的通路阻抗，以及所述电源适配器和所述终端之间的充电线线路的通路阻抗，确定所述第一充电接口与所述第二充电接口之间是否接触不良。

以上从电源适配器的角度详细描述了根据本发明实施例的快速充电过程，下面将从终端的角度描述根据本发明实施例的快速充电过程。
应理解，终端侧描述的电源适配器与终端的交互及相关特性、功能等与电源适配器侧的描述相应，为了简洁，适当省略重复的描述。
根据本发明的一个实施例，如图12所示，终端2还包括充电控制开关203和控制器204，充电控制开关203例如电子开关器件构成的开关电路连接在第二充电接口201与电池202之间，充电控制开关203在控制器204的控制下用于关断或开通电池的充电过程，这样也可以从终端侧来控制电池的充电过程，保证电池充电的安全可靠。

为了开启和使用快速充电模式，电源适配器可以与终端进行快充通信流程，经过一次或多次握手协商，实现电池的快速充电。下面结合图5，详细描述本发明实施例的快充通信流程，以及快充过程包括的各个阶段。应理解，图5示出的通信步骤或操作仅是示例，本发明实施例还可以执行其它操作或者图5中的各种操作的变形。此外，图5中的各个阶段可以按照与图5呈现的不同的顺序来执行，并且也可能并非要执行图5中的全部操作。其中，需要说明的是，图5中的曲线是充电电流的峰值或平均值的变化趋势，并非是实际充电电流曲线。
如图5所示，快充过程可以包含五个阶段：
阶段1：
终端与电源提供装置连接后，终端可以通过数据线D+、D-检测电源提供装置的类型，当检测到电源提供装置为电源适配器时，则终端吸收的电流可以大于预设的电流 阈值I2(例如可以是1A)。当电源适配器检测到预设时长(例如，可以是连续T1时间)内电源适配器输出电流大于或等于I2时，则电源适配器认为终端对于电源提供装置的类型识别已经完成，电源适配器开启适配器与终端之间的握手通信，电源适配器发送指令1(对应于上述第一指令)询问终端是否开启快速充电模式(或称为闪充)。
当电源适配器收到终端的回复指令指示终端不同意开启快速充电模式时，则再次检测电源适配器的输出电流，当电源适配器的输出电流在预设的连续时长内(例如，可以是连续T1时间)仍然大于或等于I2时，再次发起请求询问终端是否开启快速充电模式，重复阶段1的上述步骤，直到终端答复同意开启快速充电模式，或电源适配器的输出电流不再满足大于或等于I2的条件。
当终端同意开启快充模式后，快充充电过程开启，快充通信流程进入第2阶段。
阶段2：
电源适配器输出的馒头波电压可以包括多个档位，电源适配器向终端发送指令2(对应于上述第二指令)询问终端电源适配器的输出电压是否匹配电池的当前电压(或是否合适，即是否适合作为快速充电模式下的充电电压)，即是否满足充电需求。
终端答复电源适配器的输出电压偏高或偏低或匹配，如电源适配器接收到终端关于适配器的输出电压偏高或偏低的反馈时，则控制单元通过调节PWM信号的占空比将电源适配器的输出电压调整一格档位，并再次向终端发送指令2，重新询问终端电源适配器的输出电压是否匹配。
重复阶段2以上步骤直到终端答复电源适配器其输出电压处于匹配档位后，进入第3阶段。
阶段3：
当电源适配器收到终端答复电源适配器的输出电压匹配的反馈后，电源适配器向终端发送指令3(对应于上述第三指令)，询问终端当前支持的最大充电电流，终端答 复电源适配器其当前支持的最大充电电流值，并进入第4阶段。
阶段4：
电源适配器接收终端答复的当前支持的最大充电电流值的反馈后，电源适配器可以设置其输出电流基准值，控制单元107根据该电流基准值调节PWM信号的占空比，使得电源适配器的输出电流满足终端充电电流需求，即进入恒流阶段，这里的恒流阶段是指电源适配器的输出电流峰值或电流平均值基本保持不变(也就是说输出电流峰值或电流平均值的变化幅度很小，比如在输出电流峰值或平均值的5％范围内变化)，即第二交流电的峰值电流在每个周期保持恒定。
阶段5：
当进入电流恒定变化阶段时，电源适配器每间隔一段时间发送指令4(对应于上述第四指令)，询问终端电池的当前电压，终端可以向电源适配器反馈终端电池的当前电压，电源适配器可以根据终端关于终端电池的当前电压的反馈，判断USB接触即第一充电接口与第二充电接口之间接触是否良好以及是否需要降低终端当前的充电电流值。当电源适配器判断为USB接触不良，发送指令5(对应于上述第五指令)，之后复位以重新进入阶段1。
可选地，在一些实施例中，在阶段1中，终端回复指令1时，指令1对应的数据中可以附带该终端的通路阻抗的数据(或信息)，终端通路阻抗数据可以用于在阶段5判断USB接触是否良好。
可选地，在一些实施例中，在阶段2中，从终端同意启动快速充电模式，到电源适配器将电压调整到合适值的时间可以控制在一定范围之内，该时间超出预定范围则终端可以判定为请求异常，进行快速复位。
可选地，在一些实施例中，在阶段2中，可以在电源适配器的输出电压调整到相较于电池当前电压高于ΔV(ΔV约为200～500mV)时，终端对电源适配器作出关于电源适 配器的输出电压合适/匹配的反馈。其中，在终端对电源适配器作出关于电源适配器的输出电压不合适(即偏高或偏低)的反馈时，控制单元107根据电压采样值对PWM信号的占空比进行调节，从而对电源适配器的输出电压进行调整。
可选地，在一些实施例中，在阶段4中，电源适配器的输出电流值的大小调整速度可以控制一定范围之内，这样可以避免由于调整速度过快导致快充异常中断。
可选地，在一些实施例中，在阶段5中，电源适配器的输出电流值的大小的变化幅度可以控制在5％以内，即可以认定为恒流阶段。
可选地，在一些实施例中，在阶段5中，电源适配器实时监测充电回路阻抗，即通过测量电源适配器的输出电压、当前充电电流及读取的终端电池电压，监测整个充电回路阻抗。当测出充电回路阻抗>终端通路阻抗+快充数据线阻抗时，可以认为USB接触不良，进行快充复位。
可选地，在一些实施例中，开启快充模式之后，电源适配器与终端之间的通信时间间隔可以控制在一定范围之内，避免出现快充复位。
可选地，在一些实施例中，快速充电模式(或快速充电过程)的停止可以分为可恢复的停止和不可恢复的停止两种：
例如，当终端检测到电池充满或USB接触不良时，快充停止并复位，进入阶段1，终端不同意开启快速充电模式，快充通信流程不进入阶段2，此时停止的快充过程可以为不可恢复的停止。
又例如，当终端和电源适配器之间出现通信异常时，快充停止并复位以进入阶段1，在满足阶段1要求后，终端同意开启快充模式以恢复快充充电过程，此时停止的快充过程可以为可恢复的停止。
还例如，当终端检测到电池出现异常时，快充停止并复位以进入阶段1，在进入阶段1后，终端不同意开启快充模式。直到电池恢复正常，且满足阶段1要求后，终端 同意开启快充以恢复快充过程，此时停止的快充过程可以为可恢复的停止。
需要特别说明地，以上对图5示出的通信步骤或操作仅是示例，举例来说，在阶段1中，终端与适配器进行连接后，终端与适配器之间的握手通信也可以由终端发起，即终端发送指令1询问适配器是否开启快速充电模式(或称为闪充)，当终端接收到电源适配器的回复指令指示电源适配器同意开启快速充电模式时，快速充电过程开启。
需要特别说明地，以上对图5示出的通信步骤或操作仅是示例，举例来说，在阶段5之后，还可包括一恒压充电阶段，即，在阶段5中，终端可以向电源适配器反馈终端电池的当前电压，随着终端电池的电压不断上升，当所述终端电池的当前电压达到恒压充电电压阈值时，充电转入恒压充电阶段，控制单元107根据该电压基准值(即恒压充电电压阈值)调节PWM信号的占空比，使得电源适配器的输出电压满足终端充电电压需求，即基本保持电压恒定变化，在恒压充电阶段中，充电电流逐渐减小，当电流下降至某一阈值时停止充电，此时标识电池已经被充满。其中，这里的恒压充电指的是第二交流电的峰值电压基本保持恒定。
可以理解的是，在本发明的实施例中，获取电源适配器的输出电压是指获取的是第二交流电的峰值电压或电压平均值，获取电源适配器的输出电流是指获取的是第二交流电的峰值电流或电流平均值。
在本发明的一个实施例中，如图6所示，电源适配器1还包括：整流滤波单元109和控制所述整流滤波单元109是否进行工作的可控开关108，所述整流滤波单元109用于对所述多个脉动波形的电压中的一个进行整流滤波以输出第二直流电例如5V，其中，所述控制单元107还用于在确定所述充电模式为普通充电模式时，通过控制所述可控开关108以使所述整流滤波单元109进行工作，并控制所述合成单元104停止工作，所述整流滤波单元109输出所述第二直流电给所述电池充电，以及在确定所述充电模式为快速充电模式时，通过控制所述可控开关108以使所述整流滤波单元109停止工作，并控制所述合成单元104 进行工作，以使所述第二交流电加载至所述电池。
其中，整流滤波单元109包括整流二极管和滤波电容，该滤波电容可支持5V的标充，即对应普通充电模式，可控开关108可由半导体开关器件例如MOS管构成。电源适配器采用普通充电模式(或称标充)对终端中的电池进行充电时，控制单元107控制可控开关108闭合，控制整流滤波单元109进行工作，这样可以更好地兼容直流充电技术，即将第二直流电加载至终端的电池，实现对电池的直流充电。例如，一般情况下，滤波部分包括并联的电解电容和普通电容即支持5V标充的小电容(如固态电容)。由于电解电容占用的体积比较大，为了减少电源适配器的尺寸，可以去掉电源适配器内的电解电容，保留一个容值较小的电容。当使用普通充电模式时，可以控制该小电容所在支路导通，对电流进行滤波，实现小功率稳定输出，对电池直流充电；当使用快速充电模式时，直接输出第二直流电，施加到电池，实现电池快速充电。
根据本发明的一个实施例，控制单元107还用于在确定充电模式为快速充电模式时根据终端的状态信息获取快速充电模式对应的充电电流和/或充电电压，并根据快速充电模式对应的充电电流和/或充电电压对控制信号例如PWM信号的占空比进行调节。也就是说，在确定当前充电模式为快速充电模式时，控制单元107根据获取的终端的状态信息例如电池的电压、电量、温度、终端的运行参数、以及终端上运行的应用程序的耗电信息等获取快速充电模式对应的充电电流和/或充电电压，然后根据获取的充电电流和/或充电电压来调节控制信号的占空比，使得电源适配器的输出满足充电需求，实现电池的快速充电。
其中，终端的状态信息包括电池的温度。并且，当电池的温度大于第一预设温度阈值或电池的温度小于第二预设温度阈值时，如果当前充电模式为快速充电模式，则将快速充电模式切换为普通充电模式，其中，第一预设温度阈值大于第二预设温度阈值。即言，当电池的温度过低(例如，对应小于第二预设温度阈值)或过高(例如，对应大于第一预设温度阈值)时，均不适合进行快充，所以需要将快速充电模式切换为普通充电模式。在本 发明的实施例中，第一预设温度阈值和第二预设温度阈值可根据实际情况进行设定或写入控制单元(比如，电源适配器MCU)的存储中。
在本发明的一个实施例中，控制单元107还用于在电池的温度大于预设的高温保护阈值时控制开关单元102关断，即在电池的温度超过高温保护阈值时，控制单元107需要采用高温保护策略，控制开关单元102断开，使得电源适配器停止给电池充电，实现对电池的高温保护，提高了充电的安全性。所述高温保护阈值与所述第一温度阈值可以不同，也可以相同。优选地，所述高温保护阈值大于所述第一温度阈值。
在本发明的另一个实施例中，所述控制器还用于获取所述电池的温度，并在所述电池的温度大于预设的高温保护阈值时，控制所述充电控制开关关断，即通过终端侧来关断充电控制开关，从而关断电池的充电过程，保证充电安全。
并且，在本发明的一个实施例中，所述控制单元还用于获取所述第一充电接口的温度，并在所述第一充电接口的温度大于预设的保护温度时，控制所述开关单元关断。即在充电接口的温度超过一定温度时，控制单元107也需要执行高温保护策略，控制开关单元102断开，使得电源适配器停止给电池充电，实现对充电接口的高温保护，提高了充电的安全性。

具体地，在本发明的一个实施例中，如图7所示，电源适配器1还包括驱动单元110例如MOSFET驱动器，驱动单元110连接在开关单元102与控制单元107之间，驱动单元110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，在本发明的其他实施例中，驱动单元110也可集成在控制单元107中。
并且，如图7所示，电源适配器1还包括隔离单元111，隔离单元111连接在驱动单元110与控制单元107之间，实现电源适配器1的初级和次级之间的信号隔离(或变压器103的初级绕组和次级绕组之间的信号隔离)。其中，隔离单元111可以采用光耦隔离的方式，也可采用其他隔离的方式。通过设置隔离单元111，控制单元107就可设置在电源适配器1的次级侧(或变压器103的次级绕组侧)，从而便于与终端2进行通信，使得电源适配器1的空间设计变得更为简单、容易。
当然，可以理解的是，在本发明的其他实施例中，控制单元107、驱动单元110均可以设置在初级侧，这时可在控制单元107与采样单元106之间设置隔离单元111实现电源适配器1的初级和次级之间的信号隔离。

也就是说，驱动单元110的供电电源可以由供电单元112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112对第四脉动波形的电压转换得到。其中，如图8所示，控制单元107设置在初级侧时，供电单元112提供两路直流电输出，以分别给驱动单元110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111实现电源适配器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110时，供电单元112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110设置在初级侧时，供电单元112单独给驱动单元110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合成单元104输出的第二交流电转换为直流电源来供给控制单元107。

如图11所示，第二电压采样电路114可连接到第一整流单元101的第一输出端和第二输出端，实现对第一脉动波形的电压进行采样，控制单元107对第二电压采样电路114采样到的电压值进行判断，如果第二电压采样电路114采样到的电压值大于第一预设电压值，则说明电源适配器1受到雷击干扰，出现浪涌电压，此时需要把浪涌电压泄放掉，来保证充电的安全可靠，控制单元107控制开关单元102开通一段时间，形成泄放通路，将由雷击造成的浪涌电压泄放，防止雷击对电源适配器给终端充电时造成的干扰，有效地提高终端充电时的安全可靠性。其中，第一预设电压值可根据实际情况进行标定。

图14为根据本发明实施例的用于终端的充电方法的流程图。如图14所示，该用于终端的充电方法包括以下步骤：
S1，当电源适配器的第一充电接口与终端的第二充电接口连接时，对输入到电源适配器的交流电进行一次整流以输出第一脉动波形的电压。
即言，通过电源适配器中的第一整流单元对输入的交流电(即市电，例如220V、50Hz或60Hz)的交流市电进行整流，并输出第一脉动波形的电压(例如100Hz或120Hz)的馒头波电压。
S2，通过控制开关单元以对第一脉动波形的电压进行调制，并通过变压器的变换以输出多个脉动波形的电压。
其中，开关单元可由MOS管构成，通过对MOS管进行PWM控制以对馒头波电压进行斩波调制。然后，由变压器将调制后的第一脉动波形的电压耦合到次级，由次级绕组进行输出多个脉动波形的电压。
在本发明的实施例中，可采用高频变压器进行变换，这样变压器的体积可以很小，从而能够实现电源适配器大功率、小型化设计。
S3，对多个脉动波形的电压进行合成以输出第二交流电，其中，第二交流电每个周期的正半部的波峰电压大于负半部的波谷电压的绝对值，第二交流电的电压波形可如图3所示。
其中，根据本发明的一个实施例，所述变压器包括初级绕组、第一次级绕组和第二次级绕组，所述变压器根据调制后的所述第一脉动波形的电压通过所述第一次级绕组输出第二脉动波形的电压，并根据调制后的所述第一脉动波形的电压通过所述第二次级绕组输出 第三脉动波形的电压。
然后，通过合成单元对所述第二脉动波形的电压和所述第三脉动波形的电压进行合成以输出所述第二交流电。
并且，通过第二充电接口将第二交流电加载至终端的电池，实现对终端电池的充电。
S4，对第二交流电的电压和/或电流进行采样以获得电压采样值和/或电流采样值。
S5，根据电压采样值和/或电流采样值对控制开关单元的控制信号的占空比进行调节，以使第二交流电满足充电需求。
需要说明的是，第二交流电满足充电需求，是指第二交流电的至少波峰电压和波峰电流需满足电池充电时的充电电压和充电电流。也就是说，可根据采样到的电源适配器输出的第二交流电的电压和/或电流来调节控制信号例如PWM信号的占空比，实时地调整电源适配器的输出，实现闭环调节控制，从而使得第二交流电满足终端的充电需求，保证电池安全可靠地充电，具体通过PWM信号的占空比来调节输出到电池的充电电压波形如图3所示。
因此，在本发明的实施例中，通过控制开关单元直接对全桥整流后的第一脉动波形的电压即馒头波电压进行PWM斩波调制，送到高频变压器，通过高频变压器从初级耦合到次级，然后经过合成单元的合成或拼接以输出第二交流电，直接输送到终端的电池，实现电池快速充电。其中，第二交流电的电压幅值，可通过PWM信号的占空比进行调节，实现电源适配器的输出满足电池的充电需求。由此可以取消电源适配器中初级、次级的电解电容器，通过第二交流电直接对电池充电，从而可以减小电源适配器的体积，实现电源适配器的小型化，并可大大降低成本。
根据本发明的一个实施例，还根据电压采样值和/或电流采样值对控制信号的频率进行调节，即可控制输出至开关单元的PWM信号持续输出一段时间后再停止输出，停止预定时间后再次开启PWM信号的输出，这样使得加载至电池的电压是断续的，实现电池断续 充电，从而可避免电池连续充电时发热严重而导致的安全隐患，提高了电池充电可靠性和安全性。其中，输出至开关单元的控制信号可如图4所示。
进一步地，上述的用于终端的充电方法还包括：通过第一充电接口与终端进行通信以获取终端的状态信息，以根据终端的状态信息、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。
也就是说，当第二充电接口与第一充电接口连接时，电源适配器与终端之间可相互发送通信询问指令，并在接收到相应的应答指令后，电源适配器与终端之间建立通信连接，这样可以获取到终端的状态信息，从而与终端协商充电模式和充电参数(如充电电流、充电电压)，并对充电过程进行控制。
根据本发明的一个实施例，还通过变压器的变换以生成第四脉动波形的电压，并检测第四脉动波形的电压以生成电压检测值，以根据电压检测值对控制信号的占空比进行调节。
具体而言，变压器中还可设置有辅助绕组，辅助绕组可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，这样，通过检测第四脉动波形的电压可以反映电源适配器的输出电压，从而根据电压检测值对控制信号的占空比进行调节，使得电源适配器的输出匹配电池的充电需求。
在本发明的一个实施例中，所述对所述第二交流电的电压进行采样以获得电压采样值，包括：对所述第二交流电的波峰电压进行采样并保持，并对所述第二交流电的电压过零点进行采样；在所述电压过零点时对所述波峰电压进行采样并保持的波峰电压采样保持单元进行泄放；对所述波峰电压采样保持单元中的波峰电压进行采样以获得所述电压采样值。由此，能够实现对电源适配器输出的波峰电压实现精确采样，并保证电压采样值能够与第一脉动波形的峰值电压保持同步，即相位和幅值变化趋势保持一致。
进一步地，在本发明的一个实施例中，上述的用于终端的充电方法还包括：采样所述第一脉动波形的电压，并在采样到的电压值大于第一预设电压值时控制所述开关单元开通 第一预设时间以对第一脉动波形的尖峰电压、浪涌电压进行放电工作。
通过对第一脉动波形的电压进行采样，然后对采样到的电压值进行判断，如果采样到的电压值大于第一预设电压值，则说明电源适配器受到雷击干扰，出现浪涌电压，此时需要把浪涌电压泄放掉，来保证充电的安全可靠，需要控制开关单元开通一段时间，形成泄放通路，将由雷击造成的浪涌电压泄放，防止雷击对电源适配器给终端充电时造成的干扰，有效地提高终端充电时的安全可靠性。其中，第一预设电压值可根据实际情况进行标定。
根据本发明的一个实施例，还通过第一充电接口与终端进行通信以确定充电模式，并在确定充电模式为快速充电模式时根据终端的状态信息获取快速充电模式对应的充电电流和/或充电电压，以根据快速充电模式对应的充电电流和/或充电电压对控制信号的占空比进行调节，其中，充电模式包括快速充电模式和普通充电模式。
也就是说，在确定当前充电模式为快速充电模式时，可根据获取的终端的状态信息例如电池的电压、电量、温度、终端的运行参数、以及终端上运行的应用程序的耗电信息等获取快速充电模式对应的充电电流和/或充电电压，然后根据获取的充电电流和/或充电电压来调节控制信号的占空比，使得电源适配器的输出满足充电需求，实现电池的快速充电。
其中，终端的状态信息包括电池的温度。并且，当所述电池的温度大于第一预设温度阈值或所述电池的温度小于第二预设温度阈值时，如果当前充电模式为快速充电模式，则将快速充电模式切换为普通充电模式，其中，所述第一预设温度阈值大于所述第二预设温度阈值。即言，当电池的温度过低(例如，对应小于第二预设温度阈值)或过高(例如，对应大于第一预设温度阈值)时，均不适合进行快充，所以需要将快速充电模式切换为普通充电模式。在本发明的实施例中，第一预设温度阈值和第二预设温度阈值可根据实际情况进行标定。
在本发明的一个实施例中，当所述电池的温度大于预设的高温保护阈值时，控制所述开关单元关断，即在电池的温度超过高温保护阈值时，需要采用高温保护策略，控制开关 单元断开，使得电源适配器停止给电池充电，实现对电池的高温保护，提高了充电的安全性。所述高温保护阈值与所述第一温度阈值可以不同，也可以相同。优选地，所述高温保护阈值大于所述第一温度阈值。
