bq27411 EVM: System-Side Impedance Track™
This evaluation module (EVM) is a complete evaluation system for the bq27411 fuel gauge. The EVM
includes one bq27411 circuit module with a current-sense resistor. A separate orderable EV2300 or
EV2400 PC interface board for fuel gauge interface along with a PC USB cable, and Microsoft
based PC software is needed when using this EVM. The circuit module includes one bq27411 integrated
circuit and all other onboard components necessary to monitor and predict capacity for a pack-side fuel
gauge solution. The circuit module connects directly across the battery cell. With the EV2300 or EV2400
interface board and software, the user can:
Read the bq27411 data registers
Update the RAM for different configurations
Log cycling data for further evaluation
Evaluate the overall functionality of the bq27411 solution under different charge and discharge
conditions
The latest Windows-based PC software can be downloaded from the product folder on the Texas
Instruments Web site.
