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。
下面参考附图描述本申请实施例的充电装置的测试板、测试系统和测试方法,该充电装置的测试板、测试系统和测试方法用于对充电装置进行测试。
在本申请的实施例中，充电装置可用于给电子设备进行充电。电子设备可以是指终端，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。以适配器为例，充电装置可以VOOC适配器，VOOC适配器的充电电路可通过充电接口直接连接至电子设备的电池。
可理解，为了保证充电装置的安全可靠，充电装置通常设置有安全保护机制，例如，过压过流过温的保护、通路阻抗异常的保护、开关管异常的保护等。由此，在实际使用过程中，充电装置出现某种异常状态，充电装置进入保护状态。
为此，本申请实施例的充电装置的测试系统，通过测试板模拟电子设备的状态，与充电装置实时通信，故意制造异常状态，并实时监控充电装置的状态，判断充电装置是否在异常时进入相应的保护状态，从而验证各个保护功能的有效性。
下面结合图1-4详细描述本申请实施例的充电装置的测试板。
如图1所示，本申请实施例的充电装置的测试板100包括：连接电路10、第一通信模块20、第二通信模块30和控制模块40。
其中，连接电路10分别连接充电装置200和负载模块300，以使充电装置200通过连接电路10与负载模块300形成测试回路。即充电装置200输出的电 流经测试板20的连接电路10流向负载模块300，电流方向如图1中箭头方向所示。
第一通信模块20与上位机400进行通信；第二通信模块30与充电装置200进行通信，控制模块40与第一通信模块20和第二通信模块30相连。也就是说，控制模块40可通过第一通信模块20接收上位机400发送的信息也可向上位机400发送信息，同理，控制模块40可通过第二通信模块30接收充电装置200发送的信息也可向充电装置200发送信息。
需要说明的是，负载模块10可为无电池的负载，而测试板20与负载模块10配合可模拟电子设备的状态，例如，通过测试板20模拟电子设备的快充电过程中电池的状态，电池的状态包括电池电流、电池电压等，然后，测试板20再将模拟的电池状态上报给充电装置30，充电装置30可根据测试板20上报的电池状态模拟充电过程。
在测试过程中，控制模块40可通过第一通信模块20接收上位机400发送指令信息，并根据指令信息生成相应的测试指令，以使测试板100或充电装置200测试指令。
作为一个示例，上位机400可向测试板100发送指令信息，该指令信息用于指示当前测试类型，例如当前测试类型可包括过压测试、过温测试、通路阻抗测试等。控制模块40可通过第一通信模块20接收上位机400发送指令信息，并根据指令信息确定当前测试类型，并根据当前测试类型生成相应的测试指令。然后，确定所生成的测试指令的执行主体，例如，该测试指令的执行主体为充电装置200时，控制模块40可通过第二通信模块30向充电装置200发送测试指令，充电装置200执行该测试指令，以使充电装置实现相应测试类型的测试，又如，该测试指令的执行主体为测试板100时，控制模块40可直接执行该测试指令，以使充电装置实现相应测试类型的测试。
由此，能够实现自动测试，操作简单，省时省力，缩短全套测试的耗时时间。
可理解，当需要对充电装置200进行多项测试时，上位机400可按照设定好的测试时序顺序发送多个指令信息，测试板100每次接收到指令信息后，均可根据接收到的指令信息生成相应的测试指令，以根据相应的测试进行测试。并且，在当前测试完成后，上位机400可自动或根据用户输入的指令发送下一个指令信息。由此，能够自动实现全套测试，省时省力，缩短全套测试的耗时时间。
在本申请一些实施例中，在测试板100或充电装置100执行测试指令之后，控制模块40还用于获取充电装置200的状态信息，并根据充电装置200的状态信息确定测试结果的测试结果，以及向上位机400发送测试结果。
在本申请一些实施例中，在测试板100或充电装置200执行测试指令之后，控制模块40还用于获取充电装置200的状态信息，并向上位机400发送充电装置200的状态信息，以使上位机400根据充电装置200的状态信息确定测试结果。
作为一个示例，充电装置200的状态信息可包括运行状态信号例如保护状态等和输出状态信息例如输出电压、输出电流等。
具体地，当控制模块40执行测试指令时，模拟测试指令所指示的异常状态，并采集充电装置200的运行状态信息，其中，运行状态信息用于指示充电装置40是否进入保护状态。
可理解，上位机400可以给测试板100发送指令信息，指令信息可以指示测试类型，测试板100的控制模块40在通过第二通信模块30接收到指令信息之后，可以根据接收到的指令信息生成相应的测试指令，然后，控制模块40可执行该测试指令，模拟该测试指令所指示的异常状态，由于充电装置200通过连接电路10与负载模块300形成测试回路，充电装置200可检测到该异常状态，在该异常状态的保护功能正常时进入保护状态。
接下来，测试板100通过第二通信模块30接收充电装置200的运行状态信息，即充电装置200是否进入保护状态的信息。测试板100可自行根据运行状 态信息判断充电装置200是否进入保护状态或者将运行状态信息发送给上位机400，让上位机400判断充电装置200是否进入保护状态。如果充电装置进入保护状态，则确认充电装置具有该异常保护功能或者该异常保护功能有效，如果充电装置未进入保护状态，则确认充电装置不具有该异常保护功能或者该异常保护功能失效。
作为一个示例，以充电装置200到负载模块300的通路阻抗的保护功能测试为例，当进行通路阻抗保护功能测试时，控制模块40可根据测试指令模拟通路阻抗异常状态，即控制模块40可向充电装置200发送测试电池电压VBAT，充电装置200可接收测试板100上报的测试电池电压VBAT，并根据测试电池电压VBAT计算充电装置200到负载模块300的通路阻抗，以及根据充电装置200到负载模块300的通路阻抗控制充电装置200的运行状态(包括但不限于正常工作状态、保护状态等)。即在通路阻抗大于预设阻抗时，充电装置200进入保护状态，在通路阻抗大于等于预设阻抗时，充电装置200处于正常工作状态。
此时，测试板100通过第二通信模块30获取充电装置200的运行状态，并自行根据运行状态信息判断充电装置200是否进入保护状态或者将运行状态信息发送给上位机400，让上位机400判断充电装置200是否进入保护状态。如果充电装置进入保护状态，测试板100或上位机400则确认充电装置具有通路阻抗保护功能或者通路阻抗保护功能有效，如果充电装置未进入保护状态，测试板100或上位机400则确认充电装置不具有通路阻抗保护功能或者通路阻抗保护功能失效。
需要说明的是，充电装置200可根据充电装置200的充电电压、测试板100上报的测试电池电压VBAT和充电装置200的充电电流计算充电装置200到负载模块300的通路阻抗。即，充电装置30可根据以下公式计算充电装置30到负载模块10的通路阻抗：
R＝(VBUS-VBAT)/I
其中，R为充电装置30到负载模块10的通路阻抗，VBUS为充电装置30 的充电电压，VBAT为测试板20上报的测试电池电压，I为充电装置30的充电电流。
并且，控制模块40可可采样测试板上的电压，并根据测试板上的电压V-ADC、模拟阻抗增加值△R、充电装置30的充电电流I计算测试电池电压VBAT。其中，模拟阻抗增加值△R大于或等于预设阻抗。即，控制模块40可根据以下公式计算测试电池电压：
VBAT＝V-ADC-△R*I
其中，VBAT为测试电池电压，V-ADC为测试板20上的电压，△R为模拟阻抗增加值，I为充电装置30的充电电流。
具体地，当充电装置200执行测试指令时，控制装置40通过第二通信模块30向充电装置200发送测试指令，并采集充电装置200的输出状态信息，其中，输出状态信息用于指示充电装置200根据测试指令运行时的输出状态。
可理解，上位机400可以给测试板100发送指令信息，指令信息可以指示测试类型，测试板100的控制模块40在通过第二通信模块30接收到指令信息之后，可以根据接收到的指令信息生成相应的测试指令，然后，控制模块40可通过第二通信模块30向充电装置200发送该测试指令，充电装置200可执行该测试指令，进入某种测试状态。
接下来，测试板100可通过第二通信模块30接收充电装置200的输出状态信息，例如充电装置200的输出电压、输出电流等。测试板100可自行根据输出状态信息判断充电装置200的输出状态信息是否满足测试要求或者将输出状态信息发送给上位机400，让上位机400判断充电装置200的输出状态信息是否满足测试要求。
作为一个示例，以功耗测试为例，当进行功耗测试时，控制模块40可向充电装置200发送测试指令，充电装置200可根据测试指令进入某种测试场景，测试板100可通过第二通信模块30获取充电装置200的输出状态例如电压电流等。测试板100可自行根据输出状态信息判断充电装置200是否满足功耗测试 要求或者将输出状态信息发送给上位机400，让上位机400判断是否满足功耗测试要求。
下面描述测试板200的具体结构。
如图2-4所示，连接电路10可包括第一电源线101和第二电源线102。
并且，充电装置200可具有电源线，充电装置200可通过电源线向外部输出电能，例如为电子设备的电池充电，或者向负载模块300传输电能。具体地，充电装置200的电源线可包括正电源线301a和负电源线301b。其中，第一电源线101的一端连接负载模块300的正极，第一电源线101的另一端连接充电装置200的正电源线301a；第二电源线102的一端连接负载模块300的负极，第二电源线102的另一端连接充电装置200的负电源线301b。
正电源线301a还可与充电装置200的充电电路303的正输出端+相连，负电源线301b还可与充电装置200的充电电路303的负输出端-相连。
可理解，电流从充电装置200的充电电路303的正输出端+流出，依次经正电源线301a和第一电源线101流入负载模块300的正极，再由负载模块300的正极流出，依次经第二电源线102和负电源线301b流回充电装置200的充电电路303的负输出端-。
作为一个示例，在充电装置200与电子设备相连时，正电源线301a和负电源线301b可分别连接至电池的正极和负极，以为电子设备的电池进行充电。
根据图4所示，连接电路10还包括开关管103，开关管103串联在第一电源线101或第二电源线102上，控制模块40与开关管103的控制极相连，控制模块40通过控制开关管103导通或关断以控制充电装置200到负载模块300的测试回路导通或关断。
可理解，当开关管103导通时，充电装置200到负载模块100的测试回路开通，充电装置200输出电能到负载模块300；当开关管103关断时，充电装置200到负载模块300的测试回路断路，充电装置200停止输出电能到负载模块300。
控制模块40与开关管103的控制极相连，在对充电装置200进行测试时，开关管103可在控制模块40的控制下导通。开关管40可为MOS管或三极管。控制模块40可为MCU(Micro-controller Unit，微控制单元)。
具体地，以MOS管为例，如MOS管放在第一电源线101上，MOS管的漏极可靠近充电装置200设置，而MOS管的源级可远离充电装置200设置。
根据图4所示，连接电路40还可包括采样电阻R1，采样电阻R1串联在第一电源线101或第二电源线102上，采样电阻R1的两端还与控制模块40相连。也就是说，控制模块40可通过采样电阻R1采样第一电源线101或第二电源线102上的电流，控制模块40可将该电流作为测试回路的电流，并根据该电流对充电装置200进行控制，也可在电流大于预设电流时控制开关管103，从而实现过流保护。
在本申请的一些实施例中，负载模块300可为电子负载或程序电源。其中，电子负载可处于恒流模式或恒压模式。程控电源可在作为负载的同时向外供电。
具体地，当负载模块300为电子负载时，控制模块40可与外部电源50相连，以使外部电源50为控制模块40供电。当负载模块300为程序电源时，程控电源还为控制模块40供电。
也就是说，测试板100的供电可以外部供电或者使用作为负载模块300的程控电源供电，从而防止充电装置200进入保护状态后，关闭电源输出后，控制模块40掉电。
在本申请的一个实施例中，如图4所示，第二通信模块30可通过第一通信线105与充电装置200进行通信，第一通信线105、第一电源线101和第二电源线102可设置于同一线缆中。该线缆可为USB线缆或Type-c线缆，从而，便于实现充电装置与测试板之间的连接。
在本申请的一个实施例中，如图4所示，第一通信模块20可通过通信线缆与上位机400进行通信，该通信线缆可为串行通信线缆，即上位机400与测试板100之间可进行串行通信。
