Abstract
Methods and apparatus for providing uninterruptible power are provided by aspects of the invention. One aspect is more particularly directed to an uninterruptible power supply for providing power to a load. The uninterruptible power supply includes an input to receive input power, an output to provide output power, a plurality of battery modules that provide backup power, a power circuit coupled to the input, coupled to the plurality of battery modules and coupled to the output to provide power derived from at least one of the input power and the backup power to the output, a controller, a return line coupled to the controller and coupled to each of the battery modules, and a fist sense line coupled to the controller and coupled to the plurality of battery modules. The controller and each of the battery modules are configured and arranged such that at least one characteristic of the battery modules is determined by the controller based on signals detected by the controller on the first sense line.
