Batteries for stationary standby and for stationary cycling applications introduction

The term "stationary battery" tends to conjure up many interpretations among power engineers, depending on one\´s perspectives on battery energy storage. The primary application that immediately comes to mind is that for standby or UPS use, but that is not the only application for stationary batteries. Currently, changes are underway where large stationary batteries are being used in grid-tied cycling applications for distributed energy resource systems. The current IEEE standards developed for standby application do not apply to these new stationary applications, but many engineers are totally unaware of the not-so-subtle differences in standby battery and cycling battery O&M requirements. The purpose of this paper is to introduce engineers are using stationary batteries in cycling applications to the differences in battery system management standards currently in use in the IEEE to preclude the improper application of standards for standby applications with those intended for cycling applications.
