  • Low cost ultra low power in-battery charge monitor
    Publication number: 20080007222
    Abstract: Battery monitoring systems include a microprocessor and a current sensor that is coupled to periodically sample current provided by the battery. Based on the periodic samples and an initial battery capacity, the microprocessor determines a remaining battery capacity. The microprocessor and current sensor are powered by the battery being monitored, and to reduce power consumption, periodic current sensings alternate with periodic sleep periods in which the current sensor and the microprocessor are substantially disabled or operate with substantially reduced power consumption.
