Plug-In Electric Vehicle (PEV) Interoperability with Electric Vehicle Supply Equipment (EVSE)
This SAE Recommended Practice J2953/1 establishes requirements and specification by which a specific Plug-In Electric Vehicle (PEV) and Electric Vehicle Supply Equipment (EVSE) pair can be considered interoperable. The test procedures are further described in J2953/2.
This document supports the digital communication requirements within SAE J2836™ that includes the use cases and general information for several communication approaches and SAE J2847 includes the corresponding detail messages and state diagrams. SAE J2931 identifies the requirements and protocols, as various options are available to the consumer and utility. Battery Electric Vehicles (BEV) were developed several years ago and the connector, EVSE and analogue interface was described in SAE J1772™ and has been updated to better match Plug-In Hybrid Vehicle (PHEV) criteria. Utility companies are developing the smart grid communication and control system to balance this additional load with available distribution and several options will be available to the consumer. Plug-In Vehicle (PEV) and EVSE digital communication is required to insure the customer is able to roam and connector any PEV to any EVSE for these additional features. Considerably more manufacturers have entered the market PEVs and EVSEs with more BEV and PHEV combinations, and also offer a wide variety of EVSEs from 120V and 240V AC, plus DC charging where the EVSE includes an off-board charger for faster rates. This market will continue to expand and change, and the customers need to connect and charge any PEV with any EVSE using their preferred communication medium and still interface with the local utility.
