Plug-in Electrical Vehicle Charge Rate Reporting and Test Procedures
J2953/4_202106
This document facilitates clear and consistent comparisons of realistic charging capabilities of passenger vehicles via commercially available DC EVSE. Common test procedures and metrics are established for both vehicles and EVSEs operating without limitations in nominal conditions. This document does not attempt to address performance variations of EV-EVSE interactions outside of nominal conditions such as extreme temperatures, variable SOCs, and so on.
Rationale:
For the purposes of comparing charging capabilities of electric vehicles (EVs) and electric vehicle supply equipment (EVSEs), a unified methodology of reporting the charging rate is needed in the field. This document will provide common test procedures to consistently measure capabilities of vehicles and EVSEs for the consumer and media to use for clear comparisons. This document describes testing and reporting schema for direct current (DC) charging systems as applied to light duty passenger vehicles directly connected charging systems. Extensions may be added (as needed) for alternating current (AC) charge and/or wireless power transfer (WPT) systems. This document is relevant to passenger vehicles.
