请参阅图2和图3，图2是本申请实施例提供的测试***的第二种结构示意图，图3是本申请实施例提供的测试***的第三种结构示意图。该充电装置10可以包括第一整流单元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。
在一些实施例中，变压器103可以包括初级绕组和次级绕组，初级绕组的一端与第一整流单元101的第一输出端相连，第一整流单元101的第二输出端接地，初级绕组的另一端与开关单元102相连(例如，该开关单元102为MOS管，则此处是指初级绕组的另一端与MOS管的漏极相连)，变压器103用于根据调制后的第一脉动波形的电压输出第二脉动波形的电压。其中，变压器103为高频变压器，其工作频率可以为50KHz－2MHz，高频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。在本申请的实施例中，采用高频变压器，可以利用高频变压器相较于低频变压器(低频变压器又被称为工频变压器，主要用于指市电的频率，比如，50Hz或者60Hz的交流电)体积小的特点，从而能够实现充电装置10的小型化。
第二整流单元104与变压器103的次级绕组相连，第二整流单元104用于对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。其中，第二整流单元104可包括二 极管或MOS管，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，采样单元106用于对初级绕组上的电压和/或电流进行采样即对调制后的第一脉动波形的电压进行采样，从而实现初级采样。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，并根据采样单元106采样的电压值和/或电流值计算与第二整流单元的输出相对应的电压采样值和/或电流采样值，即计算得到的电压采样值和/或电流采样值对应第二整流单元的输出，为充电装置的输出电压和/或输出电流，以及根据电压采样值和/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。其中，第三脉动波形的输出电压和/或输出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，保证终端充电时的安全可靠。此外，由于电源适配器输出的是脉动波形的电压，从而无需在充电装置(电源适配器)中设置电解电容，不仅可以实现充电装置(电源适配器)的简单化、小型化，还可大大降低成本。
请参阅图4，图4是本申请实施例提供的充电***第四种结构示意图。该充电***包括充电装置10和程控电源70。
充电装置10，充电装置10包括第一充电接口105，第一充电接口105输出脉动信号。
程控电源70，程控电源70包括第二充电接口701，第二充电接口701连接充电装置10的第一充电接口105，当充电装置10输出脉动信号的电压高于第一电压阈值时，程控电源70接收并检测充电装置10输出的脉动信号，当充电装置10输出脉动信号的电压低于或等于第一电压阈值时，程控电源70给充电装置10供电。
在对充电装置10进行测试时，因为充电装置10输出的是脉动信号，即充电装置10输出上述的第三脉动波形。该脉动信号的电压是波动的，即该脉动信号包括峰值电压值(最大电压值)和谷值电压值(最小电压值)，该脉动信号的电压在峰值电压值和谷值电压值之间波动。在充电装置10给电子设备的电池直充时，若脉动信号中的电压低于一 定值时(如脉动信号的电压低于2.8V时)，脉动信号的电压会被电池电压反灌嵌位住，从而使充电装置10不断电。等脉动信号的电压高于一定值时(如脉动信号的电压高于2.8V时)，脉动信号给电池充电。
但是，在产线测试时，若使用电池进行测试，无法准确模拟电池的各种状态进行测试，如电池低电量、中电量、高电量、满电量等情况，只能测试电池的一种情况，测试效果无法满足需要。或者需要更换多个不同电量的电池，增加操作步骤，操作繁琐，而且容易弄混，造成测试失败，需要重新测试，效率低且容易出错。另外，各个不同电量的电池在测试过程中不断改变其电量，需要定期检查并放电处理，使用不方便。大批量的充电装置10进行产线流水线测试，上述问题都很难解决，严重影响效率。因此，本申请实施例使用程控电源70进行测试，使用程控电源70模拟电池各种状态，使其能够顺利、快速、完整的测试。
使用程控电源70测试，发明人在实际测试时发现，当充电装置10输出的脉动信号电压低于第一电压阈值时(如2.8V)，充电装置10会断电，以至无法正常测试。具体的，充电装置10因为输入的为交流电，而且充电装置10直接给电池充电，在交流电为低电压时，充电装置10内部的多个部件无法供电，进而导致充电装置10内部的多个部件无法工作，导致充电装置断电无法正常工作。发明人经过长时间研究，并进行大量试验后，使用程控电源70进行测试可以解决该问题。当充电装置10输出脉动信号的电压低于第一电压阈值时，程控电源70给充电装置10供电，以使充电装置10内部的多个部件继续工作。
具体的，当充电装置10输出脉动信号的电压高于或等于第一电压阈值时，充电装置10输出的脉动信号输入程控电源70进行测试。而后，当充电装置10输出脉动信号的电压低于第一电压阈值时，程控电源70给充电装置10供电。

测试***的通信模块60先发送一个控制信息至充电装置10，然后程控电源70获取充电装置10的输出信号，然后检测充电装置10的输出信号的电压或电流或频率与控制信息是否匹配，从而检测充电装置10的通信功能是否正常，同时也检测充电装置10的性能。例如，控制信息包括改变输出信号的电压，将输出电压的峰值从5V改为12V，程控电源70检测充电装置10的输出信号的峰值电压，若输出信号的峰值电压从5V变为12V，说明充电装置10的通信功能正常，且可以检测当输出信号的峰值电压为12V时的各个参数，如电流、平均电压、频率等。

请参阅图7，图7是本申请实施例提供的充电***第七种的结构示意图。该测试***还包括电子负载20，电子负载20与充电装置10连接，电子负载20用于测试充电装置10输出的脉动信号。
测试***包括电子负载20和程控电源70，电子负载20用于测试充电装置10输出的脉动信号，程控电源70用于当脉动信号低于第一电压阈值时，给充电装置10供电。
在产线测试充电装置10时，可以使用电子负载20对充电装置10进行测试。电子负载20是通过控制内部功率(MOSFET)或晶体管的导通量(量占空比大小)，依靠功率管的耗散功率消耗电能的设备。它能够准确检测出负载电压，精确调整负载电流，同时可以实现模拟负载短路。

在一些实施例中，充电装置包括温度检测单元，温度检测单元设置在电压调整电路上。控制单元与温度检测单元连接，并获取温度检测单元检测到的温度信息。控制单元将温度信息通过控制单元的通信端口发送至通信模块。程控电源的检测模块根据通信模块获取的温度信息，检测充电装置的输出电信号。
充电装置内部设有温度检测单元，该温度检测单元检测电压调整电路的温度信息，控制单元获取该温度信息，当温度信息对应的温度大于预设温度阈值时，控制单元调整电压调整电路，例如可以降低输出电压、降低输出电流、降低输出功率、间断输出电信号、停止输出电信号等。控制单元将该温度信息发送给通信模块，通信模块可以将该温 度信息展示给用户看，如通过显示屏显示、通过点亮不同颜色的LED表示不同的温度范围，然后查看对比程控电源检测到的充电装置的输出电信号，确定根据温度调整电压调整电路是否正常。也可以通信模块将该温度信息发送给程控电源，程控电源检测充电装置输出的电信号与该温度信息对应的预设输出电信号是否匹配。
请继续参阅图2和图3，控制单元107，还用于根据通信模块60的发送信息、电信号采样值对控制信号的占空比进行调节。
其中，电信号采样值包括电压采样值、电流采样值中的一项或两项。发送信息可包括模拟电池电量的信息、模拟电池温度的信息、模拟电池的电压/电流信息、模拟终端的接口信息、模拟终端的通路阻抗的信息等。
其中，需要说明的是，第三脉动波形的电压满足测试需求，可以是指第三脉动波形的电压和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根据采样到的初级侧的电压值和/或电流值来获得充电装置10输出的电压和/或电流，然后根据充电装置10输出的电压和/或电流来调节控制信号例如PWM信号的占空比，实时地调整第二整流单元的输出，实现闭环调节控制，从而使得第三脉动波形的电压满足电子设备的充电需求，保证电池安全可靠地充电。
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。译
因此，在本申请的实施例中，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，然后经过同步整流后还原成馒头波电压/电流，直接输送到电池，实现对电池的快速充电。其中，馒头波的电压幅值，可通过PWM信号的占空比进行调节，实现充电装置10的输出满足电池的充电需求。由此可知，本申请实施例的充电装置10，取消初级、次级的电解电容器，通过馒头波电压直接对电池充电，从而可以减小充电装置10的体积，实现充电装置10的小型化，并可大大降低成本。
在一些实施例中，控制单元107通过第一充电端口与通信模块60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。
其中，充电装置10和电子设备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，充电装置10输出端口数据引脚中的D+和D－可以短路。而本申请实施例中的快速充电模式则不同，本申请实施例的快速充电模式下充电装置10可以利用数据线中的D+和D－与电子设备进行通信以实现数据交换，即充电装置10与电子设备之间可相互发送快速充电指令：充电装置10向电子设备发送快速充电询问指令，在接收到电子设备的快速充电应答指令后，根据电子设备的应答指令，充电装置10获取到电子设备的状态信息，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。但本申请实施例对普通充电模式不作具体限定，只要充电装置10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。在测试时，可以通过通信模块模拟电子设备发送和接收指令。
在一些实施例中，在充电装置10使用快速充电模式输出电信号的过程中，控制单元107接收通信模块60发送的测试信息，以通过控制开关单元102不断调整充电装置10输出电信号的电流，测试信息包括仿电池电压信息。
其中，充电装置10可以不断向询问电子设备(通信模块60)的当前状态，从而不断调整充电电流和充电电压，如询问电子设备的电池电压、电池电量等。测试时，通信模块60模拟终端发送测试信息，测试信息模拟电子设备电池的电压信息、电量信息等。
在一些实施例中，在充电装置10使用快速充电模式输出电信号的过程中，控制单元107还通过第一充电接口105与通信模块60进行双向通信，通信模块60与程控电源70连接；
当程控电源70检测到第一充电接口105与第二充电接口701之间接触不良时，通信模块60发送退出信息至控制单元107，退出信息用于控制充电装置10退出快速充电模式。
程控电源70获取第一充电接口105和第二充电接口701的通路阻抗的信息，根据该通路阻抗信息判断第一充电接口105和第二充电接口701之间接触是否不良，当接触不良时，通信模块60发送退出信息至控制单元107，退出信息用于控制充电装置10退出快速充电模式。其中可以程控电源70连接通信模块60，程控电源70将接触不良信息发送至通信模块60，通信模块60再发送退出信息至控制单元107。也可以程控电源70确定 接触不良信息后发送警示信息，如显示屏显示相关信息、LED灯闪烁、喇叭发声等方式。然后用户再通过通信模块60发送退出信息给控制单元107。
上述实施例中，通信模块60可以为一个通信小板。程控电源70还可以连接一控制电脑，该控制电脑也可以连接该通信模块60。
在一些实施例中，充电装置可采用反激式开关电源、正激式开关电源、推挽式开关电源、半桥式开关电源和全桥式开关电源中的任意一种来输出脉动波形的电压。
请参阅图8，图8是本申请实施例提供的充电装置和电子设备的结构示意图。电子设备50包括第五充电接口501和电池502，第五充电接口501与电池502相连，其中，当第五充电接口501与第一充电接口105连接时，第五充电接口501将第三脉动波形的电压加载至电池502，实现对电池502的充电。
在一些实施例中，测试装置包括程控电源、通信模块和控制电脑，程控电源与控制电脑连接，通信模块也与控制电脑连接，控制电脑可以控制程控电源，也可以通过通信模块与充电装置通信。快充过程可以包含五个阶段：
阶段1：
电子设备(或测试装置)与电源提供装置连接后，电子设备(或测试装置)可以通过数据引脚D+、D－检测电源提供装置的类型，当检测到电源提供装置为充电装置时，则电子设备(或测试装置)吸收的电流可以大于预设的电流阈值I2(例如可以是1A)。当充电装置检测到预设时长(例如，可以是连续T1时间)内充电装置输出电流大于或等于I2时，则充电装置认为电子设备(或测试装置)对于电源提供装置的类型识别已经完成，充电装置开启与电子设备之间的握手通信，充电装置发送指令1询问电子设备(或测试装置)是否开启快速充电模式(或称为闪充)。
当充电装置收到电子设备(或测试装置)的回复指令指示电子设备(或测试装置)不同意开启快速充电模式时，则再次检测充电装置的输出电流，当充电装置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，再次发起请求询问电子设备(或测试装置)是否开启快速充电模式，重复阶段1的上述步骤，直到电子设备(或测试装置)答复同意开启快速充电模式，或充电装置的输出电流不再满足大于或等于I2的条件。
当电子设备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：
充电装置输出的馒头波电压可以包括多个档位，充电装置向电子设备(或测试装置)发送指令2询问电子设备(或测试装置)充电装置的输出电压是否匹配电池当前电压(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。测试装置则是模拟电池处于不同电压时的状况。
电子设备(或测试装置)答复充电装置的输出电压偏高或偏低或匹配，如充电装置接收到电子设备(或测试装置)关于充电装置的输出电压偏高或偏低的反馈时，则控制单元通过调节PWM信号的占空比将充电装置的输出电压调整一格档位，并再次向电子设备(或测试装置)发送指令2，重新询问电子设备(或测试装置)充电装置的输出电压是否匹配。
重复阶段2以上步骤直到电子设备(或测试装置)答复充电装置其输出电压处于匹配档位后，进入第3阶段。
阶段3：
当充电装置收到电子设备(或测试装置)答复充电装置的输出电压匹配的反馈后，充电装置向电子设备(或测试装置)发送指令3，询问电子设备(或测试装置)当前支持的最大充电电流，电子设备(或测试装置)答复充电装置其当前支持的最大充电电流值，并进入第4阶段。
阶段4：
充电装置接收电子设备(或测试装置)答复的当前支持的最大充电电流值的反馈后，充电装置可以设置其输出电流基准值，控制单元根据该电流基准值调节PWM信号的占空比，使得充电装置的输出电流满足电子设备(或测试装置)充电电流需求，即进入恒流阶段，这里的恒流阶段是指充电装置的输出电流峰值或平均值基本保持不变(也就是说输出电流峰值或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)，即第三脉动波形的电流峰值在每个周期保持恒定。
阶段5：
当进入电流恒定变化阶段时，充电装置每间隔一段时间发送指令4，询问电子设备电池的当前电压，电子设备可以向充电装置反馈电子设备电池的当前电压，充电装置可以根据电子设备关于电子设备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电子设备当前的充电电流值。当充电装置判断为USB接触不良，发送指令5，之后复位以重新进入阶段1。测试装置则模拟电子设备电池此状态下的情况。
当进入电流恒定变化阶段时，充电装置每间隔一段时间发送指令4，询问电子设备电池的当前电压，电子设备可以向充电装置反馈电子设备电池的当前电压，充电装置可以根据电子设备关于电子设备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电子设备当前的充电电流值。当充电装置判断为USB接触不良，发送指令5，之后复位以重新进入阶段1。测试装置则模拟电子设备电池此状态下的情况。
在测试过程中，测试装置模拟电子设备在各个不同阶段情况下进行测试。具体的，程控电源模拟电子设备电池在不同阶段情况下的电压、电流、阻抗等，通信模块模拟电子设备电池在不同阶段情况下发送的信息，通过通信模块收发的信息和程控电源检测到的电压、电流等信号来判断充电装置各个功能是否正常。
可选地，在一些实施例中，在阶段1中，电子设备(或测试装置)回复指令1时，指令1对应的数据中可以附带该电子设备(或测试装置)的通路阻抗的数据(或信息)，电子设备(或测试装置)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，从电子设备(或测试装置)同意启动快速充电模式，到充电装置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电子设备(或测试装置)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，可以在充电装置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，电子设备(或测试装置)对充电装置作出关于充电装置的输出电压合适/匹配的反馈。其中，在电子设备(或测试装置)对充电装置作出关于充电装置的输出电压不合适(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，从而对充电装置的输出电压进行调整。
可选地，在一些实施例中，在阶段4中，充电装置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，充电装置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，充电装置实时监测充电回路阻抗，即通过测量充电装置的输出电压、当前充电电流及读取的电子设备电池电压，监测整个充电回路阻抗。当测出充电回路阻抗＞电子设备通路阻抗+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，充电装置与电子设备(或测试装置)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，当电子设备(或测试装置)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，电子设备(或测试装置)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，当电子设备(或测试装置)和充电装置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，电子设备(或测试装置)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，当电子设备(或测试装置)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，电子设备(或测试装置)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，电子设备(或测试装置)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，以上的通信步骤或操作仅是示例，举例来说，在阶段1中，电子设备(或测试装置)与充电装置进行连接后，电子设备(或测试装置)与充电装置之间的握手通信也可以由电子设备(或测试装置)发起，即电子设备(或测试装置)发送指令1询问充电装置是否开启快速充电模式(或称为闪充)，当电子设备(或测试装置)接收到充电装置的回复指令指示充电装置同意开启快速充电模式时，快速充电过程开启。
请参阅图9，图9是本申请实施例提供的测试方法的流程示意图。该测试方法基于上述实施例中的测试***，该测试方法具体可以包括：
101，将充电装置连接程控电源。
102，当充电装置输出脉动信号的电压高于第一电压阈值时，利用程控电源测试充电装置输出的脉动信号。

控制信息还可以为模拟电池需要的电压值、电流值等。用于检测充电装置面对电池需要的电压值的反应，如电池需要为5V，充电装置之前的输入电压为9V，则充电装置需要将脉动信号的输出电压降到5V。
充电装置接收到控制信息后，根据该控制信息改变输出的脉动信号。程控电源检测改变输出后的脉动信息，从脉动信息中得到测试电压值、测试电流值、测试频率值中的至少一项，控制电脑根据预存的对应信息，得到控制信息对应的参考电压值、参考电流值、参考频率值中的至少一项，接着将测试电压值与参考电压值、测试电流值与参考电流值、测试频率值与参考频率值进行比较，若比较结果在范围内，如两者相差在5％以内，则判定充电装置合格，否则判定充电装置不合格。从而可以测试充电装置的普通充电是否合格、快速充电是否合格、过压保护是否合格、过流保护是否合格等不同的性能。
