  • Method and Apparatus for Estimating the Available Runtime of a Battery Backup System
    Publication number: 20230021521
    Abstract: A battery monitoring system continuously calculates the estimated runtime of a bank of batteries in a battery backup system during both a period of operation when the load current is supplied by a commercial source of AC power and during a period of operation when the commercial source of AC power is not present and the load current is supplied by the bank. The estimated runtime may be displayed to an operator and used to alert the operator if the cutoff voltage of a battery in the bank is at or near its cutoff voltage. The system may open a circuit breaker to avoid catastrophic damage before the cutoff voltage is reached.
