SAE J2836-4:2017 pdf free.Use Cases for Diagnostic Communication for Plug-in Electric Vehicles
This SAE Surface Vehicle Technical Information Report, J2836/4, establishes diagnostic use cases between Plug-in Electric Vehicles (PEV) and the Electric Vehicle Supply Equipment (EVSE). As PEVs are deployed and include both Plug-In Hybrid Electric (PHEV) and Battery Electric (BEV) Vehicle variations, failures of the charging session between the EVSE and PEV may include diagnostics particular to the vehicle variations. This document describes the general information required for diagnostics and J2847/4 will include the detail messages to provide accurate information to the customer and/or service personnel to identify the source of the issue and assist in resolution. Existing vehicle diagnostics can also be added and included during this charging session regarding issues that have occurred or are imminent to the EVSE or PEV, to assist in resolution of these items.
This document provides the general information which must be supported by SAE Recommended Practice J2847/4.
J1772 identifies Control Pilot and Proximity circuits for PEV charging. These circuits have included resistors in certain locations that allow analogue diagnostics for (1) open circuits, (2) shorts to ground and (3) short to 12 V (or 16 V). Four points on the control pilot and five on the proximity circuit have been evaluated for these three failure conditions and this document summarizes the resulting effect and whether it is detectable or not. Additional versions of this document are intended to include more information regarding from Interoperability testing to J2953.
This is the generic term used to describe the device that is physically connected and provides energy to the vehicle. EVSEs may take several physical forms, and their logical function may likewise differ substantially. Physical forms include a mobile cord set used for 120 VAC charging, a fixed or wall-mounted 240 VAC charger, or an off-board DC charger. An EVSE may also support reverse power flow (discharging).SAE J2836-4 pdf free download.
