SAE J2758-2018 PDF

Scope: This document describes a test procedure for rating peak power of the Rechargeable Energy Storage System (RESS) used in a combustion engine Hybrid Electric Vehicle (HEV). Other types of vehicles with non fossil fuel primary engines@ such as fuel cells@ are not intended to use this test procedure. Purpose The purpose of this document is to provide a test procedure to determine RESS peak power so that a vehicle??s ratio of RESS peak power rating to the sum of the Internal Combustion Engine power rating and the RESS peak power rating can be established. Because of the vehicle-specific nature of the RESS control and environment@ this test is designed to calculate the RESS peak power for a specific vehicle. As a result@ the same RESS used in a different vehicle must be retested to determine its peak power rating in the new HEV environment.
