如何在没有电池设备的情况下以编程方式模拟 Windows 工作站中的电池？

Question

出于测试目的，我需要强制 Windows 认为它​​在工作站 PC 上有电池。

有没有办法在没有电池设备的Windows工作站中伪造/模拟/模拟/模拟电池状态/低电平/充电/放电？

我可以在 Windows 上以编程方式设置电池电量吗？

tl;dr：使用 Windows 驱动程序工具包 (WDK) 中的 Windows Driver Testing Framework (WDTF) Runtime Libraries

长指令：

1. 使用 Windows 驱动程序工具包 (WDK) 安装 Visual Studio

2. 创建虚拟机

3. 在C:\Program Files (x86)\Windows Kits 中搜索WDK Test Target Setup x64-x64_en-us.msi

4. 在虚拟机上安装WDK Test Target Setup x64-x64_en-us.msi。

5. 在 Visual Studio 中，在主菜单 Driver > Test > Configure Devices 添加要安装的虚拟机 (WDTF) Runtime Libraries。

6. 从您工作站上的虚拟机复制文件夹C:\Program Files (x86)\Windows Kits\10\Testing\Runtimes\WDTF\RunTime

7. 从RunTime文件夹以管理员身份运行RegisterWDTF.exe

输出：

现在您可以在您的程序语言中使用 COM 对象“WDTF2.WDTF”，就像在这个 VBScript 示例中一样：

'
' Variable defenition 
'
Dim WDTF
Dim SimulatedBatterySystemSystemAction


'
' Create WDTF object
'
Set WDTF = CreateObject("WDTF2.WDTF")

'
'  Get your newly created SimulatedBatterySystem action interface
'
Set SimulatedBatterySystemSystemAction = WDTF.SystemDepot.ThisSystem.GetInterface("SimulatedBatterySystem")


'  enable the simulated battery
SimulatedBatterySystemSystemAction.EnableSimulatedBattery()

'  disable real batteries
SimulatedBatterySystemSystemAction.DisableRealBatteries()

'  set to DC power status
SimulatedBatterySystemSystemAction.SetSimulatedBatteryToDC()

'  set to 50% charge level
SimulatedBatterySystemSystemAction.SetSimulatedBatteryChargePercentage(50)

WScript.Sleep 10000 

'  set to AC power status
SimulatedBatterySystemSystemAction.SetSimulatedBatteryToAC()

'  enable real batteries
SimulatedBatterySystemSystemAction.EnableRealBatteries()

'  disable the simulated battery
SimulatedBatterySystemSystemAction.DisableSimulatedBattery()

这里所有 WDTF 参考：https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/content/_dtf/

Oleg 的回答很简单，但我无法让它模拟电池 - 禁用和启用真实电池的操作确实成功了。

很遗憾，我在公共 Internet 上找不到有关这些错误的信息。希望有人遇到这种情况并知道下一步该做什么！

编辑：似乎 Visual Studio 除了安装测试框架外还安装了各种驱动程序，因此仅复制 RunTime 文件夹是不够的。我最终使用来自另一个工作站的 VS 将我的工作站添加为完整目标。然后让我模拟电池。
