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. A method of monitoring a back-up power system associated with an uninterruptible power supply (UPS), the method comprising:selectively coupling a load to an AC power source or to a back-up power system including a plurality of battery packs coupled together in parallel for supplying power to the load when the AC power source is performing outside acceptable limits or fails, the plurality of battery packs including at least a first battery pack and a second battery pack;receiving, at a UPS processor, battery pack information from a first battery processor monitoring the first battery pack, the battery pack information being indicative of operational status of the plurality of battery packs, wherein battery pack information associated with battery packs other than the first battery pack is received via the first battery pack from a second battery processor monitoring the second battery pack; andtransmitting commands associated with the first and second battery processors to the first battery processor.
