The car also has certificates from the manufacturer, and those certificates have a maximum 90 day validity. The charger has to verify the certificates before providing power. Some but not all chargers let the car have internet access to renew the certificates from a manufacturer server.
Effectively, that means if your car manufacturer goes bankrupt, you lose charging ability 90 days later. Same if you only charge in places without internet connectivity.
