SYSTEM FOR MANAGING THE POWER SOURCE LIFE BETWEEN MULTIPLE INDIVIDUALLY POWERED DEVICES IN A WIRED SYSTEM AND METHOD OF USING SAME

摘要

A power management system (100) includes a group of individually powered electronic devices (101-107) connected with a power management controller (109). The power management controller (109) operates to determine the operation and charge of each power source of the electronic devices (101-107) for managing the power source life of at least one of the devices through the use of pre-selected power management algorithms. These include a preprogrammed and predictive algorithm (203, 205) based on anticipated or actual device activity, a priority algorithm (207) based on device priority or a maximize work shift algorithm (209) based on the time period of the user's work shift.
