我也试着用nim写了一个

type
    SYSTEM_POWER_STATUS* {.final, pure.} = object
        ACLineStatus*: int8
        BatteryFlag*: int8
        BatteryLifePercent*: int8
        Reserved1*: int8
        BatteryLifeTime*: int32
        BatteryFullLifeTime*: int32

var test:SYSTEM_POWER_STATUS

proc getPowerStatus*(stat:var SYSTEM_POWER_STATUS):int {.stdcall, dynlib:"kernel32", 
    importc:"GetSystemPowerStatus", discardable.}

test.getPowerStatus
echo test
echo "电池电量：",test.BatteryLifePercent

if test.ACLineStatus == 0:
    echo "笔记本，断电了"
elif test.ACLineStatus == 1:
    echo "笔记本，接通外接电源中"
else:
    echo "我觉得我可能是运行在一台台式电脑上了。"
复制代码

输出：
(ACLineStatus: 1, BatteryFlag: 1, BatteryLifePercent: 99, Reserved1: 0, BatteryLifeTime: -1, BatteryFullLifeTime: -1)
电池电量：99
笔记本，接通外接电源中
