EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of 3 V and 25 V, with a

maximum voltage drop across the sense resistor of 250 mV (1−W power dissipation).

Exceeding the specified input range may cause unexpected operation and/or irreversible

damage to the EVM. If there are questions concerning the input range, please contact a TI

field representative prior to connecting the input power.

Applying loads outside of the specified output range may result in unintended operation and/or

possible permanent damage to the EVM. Please consult the EVM User’s Guide prior to

connecting any load to the EVM output. If there is uncertainty as to the load specification,

please contact a TI field representative.

During normal operation, some circuit components may have case temperatures greater than

60°C. The EVM is designed to operate properly with certain components above 60°C as long

as the input and output ranges are maintained. These components include but are not limited

to linear regulators, switching transistors, pass transistors, and current sense resistors. These

types of devices can be identified using the EVM schematic located in the EVM User’s Guide.

When placing measurement probes near these devices during operation, please be aware

that these devices may be very warm to the touch.

Introduction

This EVM is a complete evaluation system for the bq2060A battery

management system. The bq2060A is backwards compatible with the

bq2060. New features in the bq2060A can be accessed from the EEPROM

screen in the EV2200-60 software.

For this document bq2060AEVM-00X is used for both the bq2060AEVM-001

and the bq2060AEVM-002.

1.1 Overview

The EVM includes one bq2060A circuit module, a current sense resistor, a

thermistor, an EV2200 PC interface board for gas gauge interface, a PC serial

cable, and an EEPROM connector. The latest windows based EV2200-60 PC

software can be downloaded from the TI web site. The circuit module includes

one bq2060A IC and all other onboard components necessary to monitor and

predict capacity of Li-Ion or Li-Polymer (bq2060AEVM-001) or NiMH

(bq2060AEVM-002) cells. Protection for Li-Ion or Li-Polymer cells is not in-

cluded on this module. The circuit module connects directly across the cells

in a battery. With the EV2200 interface board and software, the user can read

the bq2060A data registers, program the chipset for different pack configura-

tions, log cycling data for further evaluation and evaluate the overall functional-

ity of the bq2060A solution under different charge and discharge conditions.

1.2 Features

-Complete evaluation system for the bq2060A SBS 1.1 compliant

advanced gas gauge

-Populated circuit module for quick setup

-PC software and interface board for easy evaluation

-Software that allows data-logging for system analysis

1.3 Kit Contents

-bq2060A circuit module

-EEPROM Interface connector with wires

-Sense resistor

-EV2200 PC interface board

-PC serial cable

-Set of support documentation

bq2060A-Based Circuit Module

The bq2060A-based circuit module includes all components required for a

complete battery management solution. It includes the bq2060A gas gauge

IC, 24LC01 EEPROM and other components to accurately predict and monitor

capacity of NiMH, Li-Ion, and Li-Polymer cells.

Contacts on the circuit module provide direct connection to the cells (BAT−, 1P,

2P, 3P, BAT+) and the serial communications port (SMBC, SMBC). The

system load and charger connect across PACK+ and PACK−.

The SAFE output reflects the state of the safety output from the bq2060A and

has extra ESD protection just for evaluation purposes.

SBS Data can be logged for further evaluation by using the File | Start Data

Log menu options. Then enter the desired file name and click on | SAVE |. A

window appears asking for the desired log interval. Select a desired interval

and click | CLOSE |. An example of a data log file is shown in Table 5−1. To

stop the data log, follow the same sequence. The log file can be customized

by clicking on the check box (in the Log column) next to the data fields on the

bq2060A Data and Extended screens. All the data fields that are checked are

recorded in the log file. It is important to select the desired data fields prior to

starting a log because check-box updates made after logging starts are

ignored.

5.4 Setting Programmable bq2060A Options

The EEPROM on the EVM is configured as an example LION battery for the

bq2060AEVM-001 and for an example Nickel battery for the

bq2060AEVM-002 on delivery. The bq2060A includes 3 new EEPROM

locations that are not in the bq2060. They are: EDV TC factor, Misc Options,

and Safety Over Temperature. The bq2060A is backwards compatible with the

bq2060. Special attention should be paid to make sure the settings are

correctly changed for the pack, and application with which the bq2060A

solution is being evaluated. Do this prior to calibrating the module, described

in the following section. The bq2060A must be reset after changing EEPROM

5.5 Calibration of a bq2060A Based Module Using the EV2200-60 Software

The VFC Offset tab is used in the calibration routine. The VFC Offset screen

offers a simple-to-use interface for calibrating the Offset of the VFC. Two

different types of offset can be selected.

Figure 5−9. VFC Offset Screen

Default VFC Offset: To select this offset method, click on | Start Calibration |.

This method appies an internal short (inside the bq2060A) across the sense

resistor. With the sense resistor shorted inside the bq2060A, there is less

chance that an external current can cause a poor offset calculation. If the

circuit board induces a slight offset, then it is not compensated for with this

method.

Alternate VFC Offset: To select this offset method, click on | Start Alternate

Calibration |. This method does not apply an internal short across the sense

resistor. Care must be taken that no current is flowing through the sense

resistor. If there is current, the bq2060A applies this current to its calculations,

resulting in an inaccurate VFC offset. With no short across the sense resistor,

this method compensates for board offset as long as no current is flowing.

Once calibration is started, the Calibration Started Field displays the time

when the calibration was initiated. The Elapsed Time continually updates the

amount of time in minutes since the calibration began.

To abort the offset attempt, click on | Abort |. This halts the offset calculation

process and stores a value of 0x003800 in to the EEPROM.

If this module is installed on a pack where VCC will be present to the bq2060A

after disconnecting from the EV2200, then you can click | Continue Calibration

a popup window appears asking if you wish to seal the pack after the

calibration is complete. Click | Yes | to seal the pack after calibration or | No |

to finish calibration without sealing the pack. This also is done automatically

by the bq2060A after it completes calibration.

Figure 5−10. 3 Cell LION Calibration Screen

The LiON Calibration screen differs from the NiMH calibration screen by the

individual cell voltages and cell structure. If the Chemistry or Cell Structure

fields do not show the proper configuration in their respective fields, then

select the bq2060A Data Screen Tab, select | Options | Initialize Device |, wait

5 seconds and then return to the Calibration Tab.

The Voltage/Temperature and Current/VFC Gain screen has two frames. The

top frame is for calibrating voltage and temperature. Perform this calibration

procedure prior to the Current/VFC Gain calibration.

To perform the Voltage/Temperature calibration, enter values in the Reference

Standard column that were recorded using a traceable calibrated standard. Be

sure to measure the voltage at the connections to the bq2060AEVM-00X

module to get the most accurate results. Also be sure to add the cells together

at each individual cell field for all the cells below it. The Battery Voltage Field

should be derived from all the cells added together. If this application does not

have individual cell voltage monitoring, then only the Battery Voltage field is

displayed. Enter the temperature in the appropriate field in the Reference

Standard column. Click on the | Start | button to finish the Voltage/Temperature

calibration.

To perform the Current/VFC Gain calibration, connect a traceable calibrated

load to the bq2060AEVM-00X module as shown in Figure 5−1 or 5−2. Then

enter the Load current in the Reference Standard column, and click | Start | to

finish the Current/VFC Gain calibration.

5.6 Direct Access Communication

The Pro Screen allows direct access to all the memory in the bq2060A

including the memory above the SMBus locations providing that the bq2060A

is unsealed. The scan tool called Dwell is useful for scanning a specific

location.
