如何获得批量电池的百分比？

Question

所以，我只是想知道如何获得批量电池的百分比。
我认为这将是一件好事，如果格式是这样的：

:forever 
get-battery 
if "%battery%"=="100%" goto reached100 
goto forever 

:reached100 
echo Your battery has finished charging! 
goto forever 

Answer 1

使用WMIC

:: Variables to translate the returned BatteryStatus integer to a descriptive text 
SET BatteryStatus.1=discharging 
SET BatteryStatus.2=The system has access to AC so no battery is being discharged. However, the battery is not necessarily charging. 
SET BatteryStatus.3=fully charged 
SET BatteryStatus.4=low 
SET BatteryStatus.5=critical 
SET BatteryStatus.6=charging 
SET BatteryStatus.7=charging and high 
SET BatteryStatus.8=charging and low 
SET BatteryStatus.9=charging and critical 
SET BatteryStatus.10=UNDEFINED 
SET BatteryStatus.11=partially charged 

:: Read the battery status 
FOR /F "tokens=*" %%A IN ('WMIC Path Win32_Battery Get BatteryStatus /Format:List ^| FIND "="') DO SET %%A 

:: Check the battery status, and display a warning message if running on battery power 
IF NOT "%BatteryStatus%"=="2" (
    > "%~dpn0.vbs" ECHO MsgBox vbLf ^& "The laptop is currently running on its battery." ^& vbLf ^& vbLf ^& "The battery is !BatteryStatus.%BatteryStatus%!." ^& vbLf ^& vbLf ^& "Connect the laptop to the mains voltage if possible." ^& vbLf ^& " "^, vbWarning^, "Battery Warning" 
    CSCRIPT //NoLogo "%~dpn0.vbs" 
    DEL "%~dpn0.vbs" 
)
