Battery state of health monitoring, combining conductance technology with other measurement parameters for real-time battery performance analysis

Managers responsible for stationary battery systems may need to consider this question, “What monitoring option(s) cam be used to effectively evaluate the relative state of health of installed batteries?” This is no small issue given the proliferation of site designs and the sheer number of locations equipped with stationary batteries. Further, there seems to be no consensus among battery users or battery manufacturers regarding what to monitor. Detailing which battery operating parameter(s) will provide the appropriate technical information associated with identifying weak or failing battery strings/cells while in service is the challenge. To help clarify one of several new technical options, this paper introduces new battery monitoring models that illustrate how multiple measurement inputs can be configured to guarantee finding potential service-affecting battery faults. Once detected, this information can be sent through embedded alarm communications systems to a designated maintenance response authority
