我正在测试几台安装了 Windows 的笔记本电脑，我需要编写代码来计算“充满电”所需的时间（以秒或分钟为单位）——Windows 显示的值，以及完全放电所需的时间。指示完全放电所需的分钟数的值包含在 PowerStatus.BatteryLifeRemaining 属性中。
我找不到在哪里可以读取充满电所需的时间。我不想计算它，因为我需要与 Windows 显示的时间完全相同的时间。
CIM_Battery 方法、Win32_Battery、Win32_PortableBattery 和 PowerStatus 不提供此信息。

我可以通过 PowerShell 获取剩余的放电时间（分钟）（“BatteryLifeRemaining”参数 - 与 Windows 显示的相同），通过 PowerStatus，但不能获取“完全充电时间” - BatteryFullLifetime 参数始终为 -1。
通过 Windows PowerShell 获取“完全充电时间”（与窗口显示的相同）的方法对我很有帮助。
