IEEE Draft Recommended Practice for Sizing Nickel-Cadmium Batteries for Stationary Applications

This recommended practice covers the sizing of nickel-cadmium batteries used for standby operation in stationary applications. Recommendations are provided for applications including, but not limited to, generating stations, substations, telecommunications, switchgear and control systems, compressor stations, emergency lighting, and uninterruptible power supplies. The following topics are beyond the scope of this document: Installation, maintenance, qualification, and testing procedures; Sizing guidance for engine starting applications; Consideration of battery types other than nickel-cadmium; Renewable energy systems (e.g., wind turbines and photovoltaic systems) that may provide only partial or intermittent charging; Design of the dc system and sizing of the battery charger(s)
