Triggering a python script when charger is plugged in windows 10

I want to write a python script that will alarm the user when the battery is fully charged in his/her laptop. I can write a python script that will check the battery status every 5 minutes and when the battery is 100% charged, it will fire some alarm. But I don't want this script to be running in the background forever. Instead, I want to run this script only when the charger is plugged in. How do I access this kind of event?
