方法一：

import psutil

import psutil
battery = psutil.sensors_battery()
if battery is None:print("No battery is found.")exit()
print (battery)
percentage=battery.percent
print(f"Battery Percentage: {percentage}%")

Battery的信息中包含电池的电量，剩余时间，和当前状态。

方法二：

import wmi

def Power():c = wmi.WMI()t = wmi.WMI(moniker="//./root/wmi")batts2 = t.ExecQuery('Select * from BatteryStatus where Voltage > 0')for i, b in enumerate(batts2):# print ('PowerOnline:       ' + str(b.PowerOnline))z = str(b.PowerOnline)if z=='True':print(r'Now PC in AC')else:print(r'Now PC in DC')return z

Power（）返回值是True是AC状态，False是DC状态。
