This is an informative document covering the broadest aspects of automatic monitor systems as they apply to traction battery applications. The subject of the guide covers those monitor characteristics and features which need to be controlled, though not necessarily currently available. In addition it accommodates those characteristics which are measurable and provides interpretations of accuracy and reliability of the information generated. This publication has the status of a Technical Report - type 3.
