BQ27Z561EVM-011 EVM Single-Cell Impedance Track™ Technology

The BQ27Z561 EVM comes with the BQ27Z561 gas gauge IC and all other components necessary to measure and predict capacity of a Li-ion or Li-polymer cell. This user's guide will walk you through the following tasks:

  • Connect the necessary components together to power up the EVM
  • Installation of the necessary Texas Instruments software tools
  • Bring up the EVM for a basic chemistry and accuracy cycle check
  • Evaluate the functionality of the BQ27Z561 solution under different charge and discharge conditions

The latest Windows®-based PC software can be downloaded from the product folder on the Texas Instruments website. Use the Texas Instruments web search for Battery Management Studio on
