Battery gas gauge uses charge voltage measurements for lithium batteries

July 6, 2012 By ECN Staff

Texas Instruments Inc. introduced the first in a family of multi-chemistry, multi-cell battery management gas gauge circuits with TI’s proprietary Impedance Track capacity measurement technology. The bq34z100 power management chip is asserted to be the first gas gauge in the industry to support a wide range of lithium-ion and lithium iron phosphate chemistries in 2- to 16-cell battery packs, extending battery run-time in applications like medical instruments, power tools, e-bikes and uninterruptible power supplies. Impedance Track technology uses charge voltage measurements, battery characteristics and properties to determine a battery’s state-of-health and maintain up to a 94 percent accurate capacity measurement for the entire life of the battery. The circuit also works independently of series-cell configuration, and can reduce power consumption through an external voltage translation circuit.
