Overview

The bq76920EVM is a populated circuit board for evaluation of the bq7692000 analog front-end (AFE) along with the bq78350 Battery Management Controller that serves as part of a complete pack monitoring and protection solution for 3 to 5-series Lithium Ion, Lithium iron phosphate, and more battery chemistries.  When used with an EV2400 interface adapter and appropriate evaluaton software available from the website, it provides a complete environment to evaluate register control of the AFE or the controller configuration and demonstrate current control of a battery system with the devices.

Features
  • Populated circuit board with:
  • Bq7692000 AFE IC
  • Bq78350 Battery Management controller
  • FETs for current control
  • Test point patterns for easy evaluation

Release Infomation

Overview

bqProduction Hi-cell software offers a full suite of robust tools to assist with the process of configuring, calibrating, manufacturing and tracking printed circuit boards utilizing TI Battery management products. This includes features that allow writing a golden image followed by different types of calibration to provide desired levels of accuracy, writing date of manufacture, writing unique serial numbers, and finally validating limits for calibration parameters to spike out any inconsistencies in material. bqProduction Hi-cell software offers three (3) levels of access to allow strict control over the manufacturing process with the assembly line operator only having access to the "Start" button. bqProduction Hi-cell software supports a single station from a single computer and has inbuilt capability to maintain log files for the processed printed circuit boards.

Requires

MKST-3P-ALT-EV2300

Mode of operation dependent: Requires 1mV, 1mA accurate external power supplies able to supply current required for calibration.

Features

  • Support for MKST-3P-ALT-EV2300
  • Uses industry standard Motorola SREC format golden image programmer
  • Calibration and test automation
  • Unique serial number assignment/programming
  • Supports bq34z100-G1, bq34110, bq78350

MKST-3P-ALT-EV2300 is used as a substitute for EV2300. Separate installers may be provided for each family of products and build numbers may vary by device family.

Limitations: Recommended display resolution is 1920x1080 with maximum 125% scaling. The GUI may not show password fields and/or buttons may be moved out of the visible area when using other display settings.

 

What's new

  • Uses MKST-3P-ALT-EV2300 instead of EV2300
  • Adds support for bq78350 family of gauges
  • Separate installers for each family of products

Technical reference manual addendum for BQ78350-R3

Release Infomation

Overview

BQ78350 family of gauges firmware is a firmware-only release that can be flashed onto any existing BQ78350 hardware (such as the BQ78350, BQ78350-R1, BQ78350-R2, … devices). The firmware incorporates the CEDV Li-ion and LiFePO4 battery management controller to create a pack-based solution that provides a rich array of features for gas gauging, protection, authentication, and monitoring using the companion BQ769x0 family of analog front end (AFE) protection devices for upto 15-series cell Li-ion and Li-polymer battery packs.

The BQ78350-R1A device offers optional LED or LCD display configurations for capacity reporting. It also makes data available over its SMBus 1.1 interface. Battery history and diagnostic data is also kept within the device in non-volatile memory and is available over the same interface.

Features

The BQ78350-DEVICE-FW firmware is usable on any previous version of the BQ78350 hardware. Refer the release notes for more information.
