what  is plug and charge in EV?

Plug and Charge is a new way of automating payment for EV charging, bringing Tesla-style convenience to people who drive something other than Teslas—for instance, the 2021 Ford Mustang Mach-E. The Plug and Charge protocol tells the charging station what kind of EV you're plugging in and conveniently bills you.

Till now Plug & Charge is the simplest, most secure way for drivers to charge their electric vehicles. All drivers need to do is connect their EV's charging cable to the charge point, and the vehicle is immediately starts to charge – — with no additional user steps required.
