Operation
This section provides instructions for operating the software.
3.1
Starting the Program
With the EV2400 and the bq34110EVM connected to the computer, run bqStudio from the Desktop or
installation directory. The initial window consists of a tools panel at the top and other child windows that
can be hidden, docked in various positions, or allowed to float as separate windows. When bqStudio first
starts up the DashBoard, the Registers, and Commands windows should be open. Additional windows can
be added by clicking the corresponding icons in the tools panel at the top of the main window.
The Scan (continuous scan) or Refresh (single time scan) buttons can be clicked in order to update the
data in the Registers and Data Memory windows.
bqStudio provides a logging function which logs selected Data Registers last received from the bq34110.
To enable this function, click the Start Log button. The default elapsed interval is 4000 milliseconds, to
change this interval, go to Windows, select Preferences, choose Registers, and change Scan/Log Interval
from 4000 to 1000 milliseconds. There is no need to log faster than 1 second as the gauge will not update
the registers faster than 1 second.
The Registers section contains parameters used to monitor gauging (see Figure 2). The Bit Registers
section provides a bit-level picture of status and fault registers. A green flag indicates that the bit is 0 (low
state) and a red flag indicates that the bit is 1 (high state). Data begins to appear once the Refresh
(single-time scan) button is selected, or it scans continuously if the Scan button is selected.

Operation
3.2.1
www.ti.com
Cell Configuration
The bq34110 operates in one of two modes for measuring battery voltage. Place jumpers on the J2 and
J5 headers to select the mode of operation. See the EVM Connections section.
For packs where the stack voltage is less than 5 V:
• Enable Calibration Mode on the device by pressing the CAL_TOGGLE button on the Commands
panel. Verify that the CAL_EN flag is set in the Manufacturing Status register.
• Update the Flash Update OK Voltage parameter on the Data Memory Configuration screen to
100mV (default is 2.8V). This parameter prevents flash updates when the measured voltage is below
this setting. This can later be updated to an appropriate voltage once the dividers are configured.
• Set the Number of Series Cells parameter to the appropriate value on the Data Memory
Configuration screen.
• Reset the gauge using the RESET button on the Commands panel.
• Calibrate the stack voltage. See the Calibration section.
NOTE: The EVM can support single cell applications, where the cell voltage can drop below 2.5 V,
by providing an external 3.3-V supply to power REGIN. For voltages below 2.5V, remove the
jumper from J2 – pins 3 and 4 (upper ≤ 5-V jumper location) and apply a 3.3-V supply to the
REGIN test point.
For packs where the stack voltage is greater than 5 V:
• Enable Calibration Mode on the device by pressing the CAL_TOGGLE button on the Commands
panel. Verify that the CAL_EN flag is set in the Manufacturing Status register.
• Update the Flash Update OK Voltage parameter on the Data Memory Configuration screen to
100mV (default is 2.8V). This parameter prevents flash updates when the measured voltage is below
this setting.
• Set the VEN_EN bit to “1” in the Pin Control Config in Data Memory on the Settings screen. This
enables the external voltage divider on the EVM and disables the internal voltage divider. The VEN pin
will pulse to enable the external resistor divider only during a voltage measurement to save power.
• Set the Number of Series Cells parameter to the appropriate value on the Data Memory
Configuration screen.
• Set the Voltage Divider parameter in Data Memory on the Calibration screen. This value should be
set based on the external resistor divider setting. (For example, use ~19,200 when the J5 header is set
to the 16V setting which divides the BAT+ voltage by 19.2).
• Reset the gauge using the RESET button on the Commands panel.
• Calibrate the stack voltage. See the Calibration section.
