2.3 EVM Connections Module Connections
This section covers the hardware connections for the EVM. See Figure 1.
www.ti.com
Figure 1. bq27750 Circuit Module Connection to Cells and System Load or Charger
• Direct connection to the cells: 1N (BAT–), 1P (BAT+)
Attach the cells to the J2 terminal block. A specific connection sequence is not required, but it is a
good practice to start with the BAT– of the battery before the BAT+. A power supply set at 4 V can be
used instead of a battery for evaluation purposes.
• I2C™ (SDA, SCL)
Attach the communications interface adapter cable to J3 and to the I2C port on the EV2300.
NOTE: If the EVM board is an E1 revision, it will only work with an EV2400. If it is an A revision, the
EV2300 can be used. Ensure that shunts are placed on P2 and P3 jumpers to enable the
onboard pullup resistors. If the EV2400 is used, there will be no need for shunts on P2 and
P3 because it has internal pullup resistors.
• System load and charger connections across Charger+/Load+ and Charger-/LoadAttach the load to the J1 terminal block. The positive terminal of the load should be connected to the
terminal block position labeled PACK+. The ground wire for the load should be connected to the other
terminal block position labeled Charger-/Load-.
• Wake-up the device up from SHUTDOWN (WAKE)
Press the Wake pushbutton switch S1 to temporarily connect 1P to Charger+/Load+. This applies
voltage to the PACK pin on the bq27750 to power-up the regulators and start the initialization
sequence.
• Parameter setup
Data flash parameters should be updated to fine tune the gauge to the pack. See the bq27750
Technical Reference Manual (SLUUBI6) for help with setting the parameters.

The Battery Management Studio program provides a logging function which logs all the values of the
parameters in the Register section if running the program in “Show basic view mode”. To selectively
choose the parameters of the Register section that are scanned and logged, set Battery Management
Studio to “Show Advanced view mode”. This mode can be set via | Windows | Preferences | All Global
Settings| Show Advanced Views. Uncheck the fields that are not needed to be scanned or logged. To
enable logging, select the Log button; this causes the Scan button to be selected. When logging is
stopped, the Scan button is still selected and has to be manually deselected.
3.3 Data Memory Screen
The bq27750 data flash comes configured per the default settings detailed in the bq27750 TRM. Ensure
that the settings are correctly changed to match the pack and application for the solution being evaluated.
For ease of configuration, a text file with a gg.csv extension can be extracted, modified, and imported back
on the device. Use the export and import buttons as seen in Figure 4 to export and import gg.csv files.
The auto export button enables gg files to be exported periodically at intervals. This is useful when
debugging issues with the gauge. A Write All command is necessary if a gg.csv file is imported to ensure
that all the changes made on the gg.csv file are effected on the gauge. The Read All command is used to
read back all of the data written to the gauge so that the changes made can be verified. The Filter/Search
field enables the user to search for a particular parameter in the data memory content.
NOTE: Do not make modifications to the gg.csv file using Microsoft Excel®as it makes changes to
file, which bqStudio rejects. Make sure to use a text editor like Notepad or similar to edit a
gg.csv file.
Battery Management Studio
3.4 Calibration Screen
The voltages, temperatures, and currents should be calibrated to provide good gauging performance.
Press the Calibration button while in the “Show Advanced view mode” to select the Advanced
Calibration window, see Figure 5. If in the “Show basic view mode”, the basic calibration window shows
when the Calibration button is clicked. The Advanced Calibration window enables the internal
temperature sensor as well as the external thermistor to be calibrated.
