摘要:
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.
