This standard specifies the performance characteristics of battery chargers that continuously maintain a battery's state of charge while simultaneously providing dc power to connected loads. These battery chargers provide transformer isolation of the dc output from the input and are designed for stationary applications. Telecommunication applications are beyond the scope of this standard.
This guide discusses operational parameters that may be observed by battery monitoring equipment used in stationary applications, and the relative value of such observations. Although this guide does not give a listing of commercially available systems, it does provide a means for establishing specifications for the desired parameters to be monitored.
This guide provides information on the differences between stationary standby and stationary cycling applications and appropriate battery management strategies in cycling operations. While the primary emphasis is on lead-acid batteries, information is also provided on alternative and emerging storage technologies. The management of battery systems in stationary standby service is covered in other IEEE documents and is beyond the scope of this guide.
This recommended practice defi nes the areas of recommended knowledge for installers and maintainers of stationary standby batteries (primarily lead-acid and Ni-Cd standby batteries) and related systems to the extent that they aff ect the battery, personnel safety and reliability of any related systems. Designing the dc system (including any connected ac inverters) and sizing of the dc battery charger(s) are beyond the scope of this recommended practice. While some of the battery information… read more covered by this practice applies to small off - grid cycling applications, information relative to large energy storage cycling applications is limited. read less
This recommended practice provides guidance for the design of stationary dc power systems. The components of the stationary dc power system addressed by this recommended practice include the following: - Storage batteries - Static battery chargers/rectifiers (including sizing) - Distribution equipment - Protection equipment - Control equipment - Interconnections - Instrumentation Guidance for selecting the quantity, types, and ratings of equipment is also provided. The considerations of each of… read more these different components and the issue of load voltage and other load specifics are discussed in terms of their effect on the design of the whole system. Guidance on short-circuit calculation and contribution of different dc power system components is also offered to improve reliability, performance, and safety of the installation. read less
