Latest Patents
David Canny holds a patent for a "Battery capacity measurement circuit." This invention involves an electronic circuit and a method for accurately measuring intermittent current pulses supplied by a storage battery to energize a load. The preferred embodiment utilizes an analog integrator that accumulates current pulses in response to a voltage drop across a sense resistor connected in series between the storage battery and the load. The voltage drop is proportional to the flow of current from the battery through the load. The output of the integrator is filtered with a low pass filter to block high-frequency noise, and the filtered output is sent to an analog to digital (A/D) converter. This converter transforms the analog signal into a corresponding digital signal, which is then processed by a processor. The processor actuates a reset switch to zero the output of the analog integrator at the end of each integration time period and recalibrates the circuit at predefined intervals to improve measurement accuracy. The processor samples the output of the A/D converter every 100 milliseconds, with calibration typically performed every 15 minutes while the load is energized from an AC source. This measurement circuit is an integral part of a battery management system that also includes a charge circuit for recharging the battery.
