Latest Patents

Huffman holds a patent for a "Battery Thermal Runaway Monitor." This device is designed to determine a thermal runaway condition in nickel-cadmium batteries. It utilizes a current sensor that develops a DC voltage proportional to the battery current. A converter then transforms this voltage into a pulse train, with a frequency directly proportional to the battery current. The pulse train frequency is monitored over fixed periods, and changes in frequency are analyzed to determine the slope of the charge current. A maximum allowable slope is specified and fed into a binary up/down counter, which counts the pulse train frequency. If the difference between two pulse train frequency readings exceeds the maximum allowable, a potential thermal runaway condition is indicated. After a predetermined number of consecutive indications, an indicator is activated to provide a warning.
