SAE J2836/5_202603

This SAE Information Report establishes the Use Cases for communications and customer-focused Key Performance Indicators (KPI) between plug-in electric vehicles (PEVs) and their customers. The Use Case Scenarios define the information to be communicated related to customer convenience features for charge on/off control, charge power curtailment, customer preference settings, charging status, electric vehicle supply equipment (EVSE) availability/access, and electricity usage, plus customer information resulting from conflicts to charging preferences. It also addresses the KPI that can provide a uniform set of metrics to quantitively assess the charging experience. This document only provides the Use Cases that define the communications requirements to enable customers to interact with the PEV and the KPI to optimize their experience with charging a PEV. Specifications such as protocols and physical transfer methods for communicating information are not within the scope of this document. Electric vehicle (EV) sales account for a rapidly growing portion of the light-duty vehicle market. However, the growth of EV adoption is inherently tied to the reliability and usability of public EV charging. Today, customers of public charging stations, EV drivers, frequently encounter problems, such as lengthy wait times, trouble starting charging sessions, and slow charging speed. It is crucial for the EV charging industry to understand and address these issues to improve the customer experience and ensure a continuing upward trend in EV adoption. This update intends to include material in the ChargeX Consortium’s Working Group 1: Defining the Charging Experience into this SAE Technical Information Report.
