The purpose of J2931/6 is to complement J2954 and J2847/6 as it describes the physical layer communication between
the EVSE and the PEV. The use cases for communications between a PEV and the utility are described in J2836/6™ with
the message details included in J2847/6. This document is intended to describe the issues with PEV association,
interoperability with various PEVs and EVSE suppliers, utilities, etc. as multiple manufacturers introduce their products.
Several scenarios are encountered as the customers determine their home application to PEV energy needs that also
includes the Home Area Network (HAN) that interfaces with home appliances and the utility. Some customers will interface
with the utility using multifamily dwellings, street parking, energy transfer at work, businesses and these all have their
variations on how the PEV communicates.
