SECC

Also called: Supply Equipment Communication Controller A Supply Equipment Communication Controller, or SECC, is the communication controller on the EVSE side of the ISO 15118 interface. It exchanges high-level messages with the Electric Vehicle Communication Controller in the vehicle. The SECC participates in establishing the communication session and handles ISO 15118 messages used for charging control, authorisation and other supported services. A charge point controller can host SECC functionality as part of a wider EVSE control design. The SECC role itself is defined by the vehicle-to-EVSE communication architecture, not by the physical form of the controller board.
