There is quite a bit more background material in my article:

In order to use PnC, a vehicle must have a unique public key certificate issued and installed very similarly to how a secure website needs a certificate and matching private key to have an “https” URL that authenticates its identity to users and their browser software. The PnC certificates are based on the same X.509 standard used for Internet website certificates......
With all of this in place, a driver can arrive at a charger, perhaps at an Electrify America site, and plug in their car. This would automatically result in their car creating a TLS (also known as SSL) connection to the charging station almost exactly the way a browser would connect to a website with an https URL.
The actual communications involved are very much like a web transaction because CCS sets up a private network between the charger and the vehicle based on the same Internet protocol standards like TCP, UDP, IP, and TLS that are used between a home Internet router and your home’s network-connected computers and other devices.
