Is it correct for the property to unplug the charging head after charging?

For the sake of safety. After charging, the indicator light changes, but there is still current flowing, which will promote the aging of components for a long time, and the charger will have short circuit and unsafe factors over time.

Electric car charger only changed the lights. Only the green light shows that it is fully charged. If the green light is not displayed, it proves that it is not fully charged. This kind of battery will sulfide if stored, so it is best to unplug the charger when it is fully charged.
