This SAE Recommended Practice provides for common battery designs through the description of dimensions, termination, retention, venting system, and other features required in an electric vehicle application. The document does not provide for performance standards. Performance will be addressed by SAE J1798. This document does provide for guidelines in proper packaging of battery modules to meet performance criteria detailed in J1766.
The Battery Size Standardization committee recommends moving this standard into “Stabilize” status at this time. The committee is currently evaluating transitioning the standards work at the battery cell level instead of at the battery pack or battery module level. With the many new variations of both automotive and non-automotive applications there are emerging many new technologies that may require different packaging, but today the OEMs are focusing their efforts on getting to a set of standard battery cells. This standard may still be quite applicable for many applications, especially for the emerging 48V and 12V stop/start applications therefore we do not want to abandon it but rather to keep it on the books.
