[C++知识库]windows系统C++获取当前电脑电池信息

系统API结构介绍：
  /*  ACLineStatus: Byte; {0:电源断电; 1:电源正常; 255:电源状态未知}
    BatteryFlag: Byte; {1:电量充足; 2:电量低; 4:电池基本耗尽; 8:充电; 128:没有电池; 255:电池状态未知}
    BatteryLifePercent: Byte; {0..100:所剩电量百分数; 255:未知}
    Reserved1: Byte; {保留, 须为 0}
    BatteryLifeTime: DWORD; {电池剩余能量; -1 表示未知}
    BatteryFullLifeTime: DWORD; {电池总能量; -1 表示未知}*/
