BATTERY COMMUNICATION SYSTEM
First Claim
1. A UPS system employing a back-up power system for supplying electrical power to a load when power from an AC power source is performing outside of acceptable limits or fails comprising, in combinationa power control circuit, including a UPS processor, for coupling to an AC power source and to a back-up power system including one or more battery packs coupled together in parallel for supplying power to a load when an AC power source is performing outside acceptable limits or fails anda battery communication system including, in combination with the UPS processor,a plurality of battery pack monitors, one monitor being associated with one battery pack in the parallel coupled array of one or more battery packs,each monitor including a battery processor coupled to its associated battery pack for receiving, processing and storing battery pack information anda communication lead line coupled to the UPS processor and the monitor processors for transmission of battery pack information among the monitor processors and the UPS processor.

Abstract
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.
