bq34110EVM Quick Start Guide

This section provides the step-by-step procedures required to take a new EVM and configure it for
operation in a laboratory environment.

2.1

Items Required for EVM Setup and Evaluation

The following items are required to set up and evaluate the EVM:

bq34110 EVM

EV2400

communications interface adapter

USB cable to the communications interface adapter to the computer

Windows 7 capable PC (or higher)

DC power supply. (Constant current and constant voltage capability is desirable.)

If using the EV2300 (older version of interface adapter), USB drivers need to be installed. See the EV2300
product page for details:

http://www.ti.com/tool/EV2300

2.2

Battery Management Studio (bqStudio) Software

bqStudio is a graphical user interface that allows the user to interact with the bq34110 device.

1. Download the latest version of

bqStudio.

The latest version listed as BQSTUDIOTEST is

recommended since it will contain the latest improvements (bq34110 needs v1.3.80 or later).

2. Run the installer. Make sure to ‘Run as Administrator’

3. Follow the on-screen instructions until completing the software installation.

4. Before starting the evaluation software, connect the EV2400 to the PC using the USB cable. The

EV2400 driver will install automatically.

2.3

EV2400 Firmware Updater

The EV2400 firmware is updated periodically. The bqStudio software will indicate which firmware version
is detected in the Dashboard. It is recommended to use v0.18 or later. If needed, the EV2400 Firmware
Updater is available at

http://www.ti.com/tool/ev2400.

The EV2400 User’s guide contains detailed

instructions for using the Firmware Updater.

2.4

Update bq34110 Device Firmware

The bq34110 may need updated firmware. Updating to the latest firmware version is recommended if it is
not already using the latest version.

1. 1. Download the latest bq34110 Firmware bundle from:

http://www.ti.com/product/BQ34110/toolssoftware

2. The installation will place the extracted files in a folder in ‘C:\ProgramData\Texas Instruments\’. Copy

the .bqz file to the directory: ‘C:\ti\BatteryManagementStudio\config’. This will ensure bqStudio has the
latest updates and tools for bq34110 evaluation.

3. Find the .srec file in the same folder from Step 2. Follow the directions in Section 3.5 to use bqStudio

to program the latest firmware .srec to the device.

4. Once programming is finished, the EVM is ready to use with the latest firmware.

2.5

EVM Connections

The bq34110 evaluation system comprises three hardware components: the bq34110 circuit module, the
EV2400 PC interface board, and the PC.

2.5.1

Connecting the bq34110 Circuit Module to a Battery Pack

Figure 1

illustrates the board connections to a battery pack.
