本SAE地面车辆技术信息报告SAE J2836/4建立了插电式电动汽车（PEV）和电动汽车供电设备（EVSE）之间的诊断用例。随着PEV的部署，并包括插电式混合动力（PHEV）和电池电动（BEV）车辆变体，EVSE和PEV之间的充电会话故障可能包括特定于车辆变体的诊断。本文件描述了诊断所需的一般信息，SAE J2847/4将包括向客户和/或服务人员提供准确信息的详细信息，以确定问题的来源并协助解决。 在充电过程中，还可以添加和包括现有的车辆诊断，以帮助解决电动车辆供电设备或PEV已经发生或即将发生的问题。

This SAE Surface Vehicle Technical Information Report, SAE 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 SAE 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.
