Abstract

The author describes principles and equipment for automatic battery supervision in telephone exchanges and the advantages involved. To simplify maintenance and supervision, a computer-based system for remote supervision of batteries has been developed. The system, BMP 610, reduces the costs of maintenance to a minimum and improves the reliability. The supervisory system can supervise all types of stationary lead storage batteries. The system is part of a major power management system, the Ericsson Energymaster, for supervision of power plants and cooling plants in telephone exchanges. The supervisory system supervises many conditions of the batteries, and issues alarms if necessary. Wiring, cell voltage deviations, level of electrolyte, leakage, high temperature, low status, and short reserve time are supervised
