1 Introduction
The bq26220EVM-001 is a complete evaluation system for the bq26220 flash-based battery
monitoring IC. The EVM includes one bq26220 circuit module, an EV2200 PC interface board
for gas-gauge evaluation, a PC serial cable, and Windows-based PC software.The circuit
module includes one bq26220 and all other components on-board necessary to monitor capacity
and other critical parameters in a one-cell Li-Ion battery pack.The circuit module connects
directly across the cell in a battery. With the EV2200 interface board and software, the user can
read the bq26220 data registers and evaluate the functions of the bq26220 under different
charge and discharge conditions
