Abstract :
The adoption of sealed lead-acid batteries and switching rectifier unit systems in DC power supplies (DC UPS) provided with a back-up function by a storage battery, has made it possible to realize a compact, lightweight, and maintenance-free design for DC switching power supply systems. The authors report on a method for monitoring the conditions of sealed storage batteries, which allows calculations and display of remaining battery discharge time during discharge, and also the optimum charging method of the batteries. They also give an example of the optimum configuration of a system incorporating these functions
