Abstract
The thesis provides an overview of batteries remote monitoring system. It describes different battery types used in uninterruptable power supply systems for telecommunication, used rectifier system and software. Due to understanding of the technologies and realization of this project, key elements of the battery monitoring system are described.
Modern base transceiver stations of mobile operators have nowadays constant load profiles. This is a result of modern digital mobile telephone systems. Complete power supply system offers high level of automatization and ability of remote monitoring of each equipment. Remote data access is commonly available only via mobile network. Power outage is rare and consequently there is also rare situations when batteries are discharging. This is a main reason for battery monitoring system, due to monitoring batteries and locating fault when batteries are in float mode.
As the central part of the battery monitoring system is used monitoring unit S-BMM2, which was developed in company SITEL and is used for monitoring DC voltages and currents in DC power supply systems. Communication interface is used for data sending to a server which runs web application.
Last part of the thesis includes tests of three different batteries sets. Voltage and current monitoring is automatic. All measurements are present in different charts, depends on type of data. Based on results, at the end statements and conclusions are given.
