Recommended Practice for Performance Rating of Electrical Vehicle Battery Modules
|Publication Date:||1 January 1997|
1. Scope--This SAE Recommended Practice provides for common test and verification methods to determine Electric Vehicle battery module performance. The document creates the necessary performance standards to determine (a) what the basic performance of EV battery modules is; and (b) whether battery modules meet minimum performance specification established by vehicle manufacturers or other purchasers. Specific values for these minimum performance specifications are not a part of this document.
1.1 Field of Application--Electri
1.2 Product Classification--Elec
1.3 Form--An Electric Vehicle propulsion battery will consist of a battery configuration of several (typically 12 V) modules interconnected in one or more series strings. This document provides test methods to determine performance of such modules, including but not limited to modules built in accordance with SAE J1797. Use of this document is intended for independently packaged modules operating at ambient temperature. Testing of a fully configured propulsion battery system, or battery subsystems designed to operate at elevated temperatures, is expected to require additional testing methods beyond those included in this document.
