BACK-UP POWER SYSTEM

摘要

A back-up power system having a monitoring system for determining, and for allowing remote monitoring of, a back-up time can be provided by a plurality of batteries for a given application, at all times. The back-up power system includes a plurality of batteries (10(1) to (10(n)), each having an integrat ed circuit adapted to monitor individual battery's state of health. The back-up power system also includes a data management unit (25) for evaluating the ba ck- up time available from the plurality of batteries based on a sum of individu al battery available capacity, a measured ambient temperature (35) and a continuously updated measured application current load (34). The available back-up time and the measured application current load are accessible to a remote user (30) via a communication link (28).
