Interfacing the aluminium-air battery with telecommunications equipment
The tests carried out by British Telecom (BT) on the aluminum-air battery with regard to using the battery in a standby power system are described. The background to BT's interest in the aluminium-air battery is outlined along with the design considerations of a prototype power system to be installed in the switching network. The need for an interfacing DC/DC converter between the battery and the equipment is described, and the converter's novel features and operation are explained.<<ETX>>
Further development of the aluminum-air telecommunications reserve power source
Aluminum-air power sources for reserve applications have undergone successful discharge testing with a variety of potential users. Their diverse requirements have expanded the initial operational range of the units, which were characterized as 600 W and 1.2 kW. The introduction of a new cell which permits operation at higher power levels (6 kW) is described. It is concluded that under typical usage profiles likely to be desired in Europe and North America, aluminum-air power sources are cost- and space-effective alternatives to conventional diesel generator sets and secondary battery systems.<<ETX>>
Telecommunications Power System Reliability in the U.K.
This paper describes the U.K. exchange power systems and their reliability targets which are successfully attained in practice. Elemental parts of the power systems are discussed in detail, and the advantages of a new rectifier sub-system explained. Advances towards distributed power systems are then proposed.
