METHODS AND SYSTEMS FOR WARNING USERS OF A DEGRADED BACKUP CAPACITY IN BATTERY PLANTS
First Claim
1. A method of warning a user when a backup capacity of a battery plant in a system is substantially degraded, the method comprising:
- determining a baseline capacity for the battery plant by estimating a reserve time of the battery plant while the battery plant is installed in the system;
determining a present capacity of the battery plant by estimating the reserve time of the battery plant while the battery plant is installed in the system;
comparing the present capacity with the baseline capacity; and
generating a warning when the baseline capacity exceeds the present capacity by more than a defined amount.

Abstract
A method of warning a user when a reserve time of a battery plant in a system is substantially degraded is disclosed. The method includes determining a baseline capacity for the battery plant by estimating the reserve time of the battery plant while the battery plant is installed in the system, subsequently determining a present capacity of the battery plant by estimating the reserve time of the battery plant while the battery plant is installed in the system, comparing the present capacity with the baseline capacity, and generating a warning when the baseline capacity exceeds the present capacity by more than a defined amount. Example embodiments of systems and control circuits configured to perform the methods are also disclosed herein.

10. A non-transitory computer readable medium storing computer-executable instructions for warning a user when a backup capacity of a battery plant in a system is substantially degraded, the instructions configured to determine a baseline capacity for the battery plant by estimating a reserve time of the battery plant while the battery plant is installed in the system, determine a present capacity of the battery plant by estimating the reserve time of the battery plant while the battery plant is installed in the system, compare the present capacity with the baseline capacity, and generate a warning when the baseline capacity exceeds the present capacity by more than a defined amount.
- 11. A system for warning a user when a backup capacity of a battery plant is substantially degraded, the system comprising a power plant including a main power supply for providing power to a load and a battery plant coupled to the main power supply, the battery plant including one or more batteries for providing power to the load when the main power supply is inoperable, and a control circuit coupled to the power plant and configured to determine a baseline capacity for the battery plant by estimating a reserve time of the battery plant while the battery plant is installed in the system, determine a present capacity of the battery plant by estimating the reserve time of the battery plant while the battery plant is installed in the system, compare the present capacity with the baseline capacity, and generate a warning when the baseline capacity exceeds the present capacity by more than a defined amount.
