An uninterrupted power supply ("UPS") system is disclosed which uses a battery communication system to communicate to a UPS processor information concerning the status of a battery pack in an array of parallel coupled battery packs. The battery packs provide back-up power for the UPS system. Information about the battery packs is collected by a monitor associated with each of the battery packs. The monitors measure battery pack voltage, currents and temperature and compile information about the battery pack from the measured values. Each monitor prepares a data word representing information about its battery pack. The data words are transmitted to the UPS in response to commands issued by the UPS processor to the monitors.

[ What is claimed is:] [1.]1. A UPS system for supplying electrical power to an electrical load comprising, in combination,a plurality of battery packs electrically coupled in parallel,a UPS processor,a power circuit adapted for coupling to a load and to a main power source and coupled to the battery packs for supplying power from the battery packs to a load,a plurality of battery pack monitors with each monitor coupled by a battery information sensor to at least one local battery pack for monitoring local battery information and including a programmed monitor processor for processing local battery information and for transmitting battery information to the UPS processor over a communication line.
