你试过查看电源管理 API 吗？
以下是代码片段：
#include <Windows.h>
GUID currentPowerScheme;
PowerGetActiveScheme(NULL, ¤tPowerScheme);
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, ¤tPowerScheme, &subGroup, &powerSetting, batteryStopThreshold);
}

Did you try looking at the power management API?
Here is the code snippet:
#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);
}
