scope:

This international standard specifies the communication between the electric vehicle (EV), including battery electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV), and the EV supply equipment. The application layer message sets defined in this revision of ISO 15118-2 are designed to support the electricity power transfer between an EV and an EV supply equipment. The bidirectional electricity power transfer, use case of that was already included in edition 1.0 of part 1 but not included in part 2, was officially added to the scope of this standard. Herein edition 2.0 of part 2 defines the communication messages and sequence requirements for bidirectional power transfer. Also the scope is widely extended in this revision, requirements of wireless communication for both conductive charging and wireless charging are defined. Additionally, requirements of communication for automatic connection device and information services about charging and control status are defined in this revision. The purpose of this part 2 of ISO 15118 is to detail the communication between an electric vehicle communication controller (EVCC) and supply equipment communication controller (SECC). Aspects are specified to detect a vehicle in a communication network and enable an Internet Protocol (IP) based communication between EVCC and SECC.
