  • Monitoring battery health in an HVAC system
    Patent number: 8423238
    Abstract: Systems and methods of monitoring battery health in an HVAC system. The charge state of a rechargeable battery and the number of amp-hours provided to or from the rechargeable battery are monitored. The number of amp-hours provided is recorded and an end-of-life condition is detected based on the number of amp-hours provided during the charge or discharge cycle. In some constructions, the end-of-life condition is detected by comparing the number of amp-hours provided during the charge or discharge cycle to a threshold. In some constructions, the end-of-life condition is detected by calculating a rate of change of the number of amp-hours provided during a charge or discharge cycle and comparing the rate of change to a threshold.
