Texas Instruments announces a unique 'gas gauge' technology that calculates remaining capacity in lithium-based battery packs with up to 99% accuracy throughout the entire life of a battery. The Impedance Track™ technology allows designers and users of portable medical, industrial appliances, and notebooks to prolong battery use and always know the exact amount of potential energy left inside the battery. Impedance Track technology precisely gauges changes in impedance, or resistance caused by battery age, temperature and cycle patterns, to accurately predict run-time of two-, three- and four-cell battery packs. The technology, which sits inside TI's Flash-based bq20z8x gas gauge chipset, analyzes precise state of charge when a battery pack is in a relaxed state by correlating between a battery pack's open circuit voltage and the current state of charge and temperature.
