Setting the CEDV Parameters

To ease evaluation of the bq34110, users can obtain the CEDV parameters from our online gauging
parameter calculator (GPC) for the CEDV gauges tool (

www.ti.com/tool/GPCCEDV

). After programming

the design parameters to the gauge, the EVM can be used to obtain the experimental data needed to
calculate the CEDV coefficients.

Figure 8. CEDV Coefficients Calculation Flow

The equipment necessary is as follows:

bqStudio software

bq34110EVM-796

Power supply able to source/sink current. A DC power supply and electronic load.

See the

Simple Guide to CEDV Data Collection for Gauging Parameter Calculator (GPC)

user's guide

(

SLUUB45

for a detailed explanation of the CEDV coefficients data collection process and GPC tool

configuration.

Use the

GPC Cycle

plug-in to control the collection of the log files and the

GPCPackager

plug-in to

package the files into a zip file to import to the online GPCCHEM tool.
