Zusammenfassung:A power management system uses software to predictively estimate remaining battery endurance by considering battery usage in context of a predetermined battery output and equipment load profiles, and appropriately issuing a shutdown alert or commencing a shutdown event as the end of battery endurance nears. More particularly, a battery supplies power to electrical equipment when a primary power source fails. Initially, the system receives one or more estimates of the battery's endurance and capability of supplying electrical power to the equipment. The system tracks battery use by prescribed electrical equipment. Utilizing software, for example, the system determines when estimated endurance minus battery usage equals a predetermined difference. Relative to this time, the system takes appropriate action(s) such as initiating shutdown of the equipment or issuing a shutdown alert.
