C++ WINAPI 充电

Question

使用 WINAPI C++，当我的笔记本电脑电量达到 95% 时，我需要停止充电，我该怎么做？

尝试挖掘 winapi 文档但没有找到任何东西

Answer 1

您是否尝试查看电源管理 API？ 这是代码片段

#include <Windows.h>

GUID currentPowerScheme;
    PowerGetActiveScheme(NULL, &currentPowerScheme);
    SYSTEM_POWER_STATUS powerStatus;
    GetSystemPowerStatus(&powerStatus);
    ULONG batteryCapacity = powerStatus.BatteryLifePercent;
    DWORD batteryThreshold = 95;

if (batteryCapacity >= batteryThreshold) {
        GUID subGroup = GUID_ACDC_POWER_SOURCE;
        GUID powerSetting = GUID_BATTERY_DISCHARGE_THRESHOLD;
        DWORD batteryStopThreshold = batteryThreshold * 100;
        POWER_SETTING_VALUE value;
        value.ValueLength = sizeof(DWORD);
        value.Data = &batteryStopThreshold;

        PowerWriteACValueIndex(NULL, &currentPowerScheme, &subGroup, &powerSetting, batteryStopThreshold);
   }
