BQ27Z746-DEVICE-FW
BQ27Z746 電量計韌體系列
BQ27Z746-DEVICE-FW
概覽
BQ27Z746-DEVICE-FW 是一個僅限韌體 (FW) 版本，可以閃存到任何現有硬體 (例如 BQ27Z746 產品) 上。該韌體採用 Impedance Track™ 專利技術，建立基於電池組的解決方案，爲 1 節鋰離子和鋰聚合物電池組提供氣體計量、保護和差分電池感測類比輸出和驗證提供豐富的功能。
BQ27Z746 系列的電量計韌體透過其整合式高性能類比周邊設備啟用裝置，並測量並維護鋰離子或鋰聚合物電池的可用容量、電壓、電流、溫度和其他重要參數的準確記錄，並將此資訊呈報至系統主機控制器。整合式防護可針對過電壓 (OVP)、電壓過低 (UVP)、充電/放電過電流 (OCC/OCD)、短路放電 (SCD) 和電池感測保護 (BCP、BCN、BDP 和 BDN) 提供安全防護。
SHA-2 驗證使用驗證金鑰適用的安全記憶體，可以識別真正的電池組。。
BQ27Z746-DEVICE-FW 韌體可用於任何舊版 BQ27Z746 硬體。
特點
- 支援含強化健全狀態 (SOH) 演算法的電池組側計量

Overview
The BQ27Z746-DEVICE-FW is a firmware (FW)-only release that can be flashed onto any existing hardware such as BQ27Z746 product. The firmware incorporates the patented Impedance Track™ technology to create a pack-based solution that provides a rich array of features for gas gauging, protection, differential battery sensing analog output, and authentication for 1-series cell li-ion and li-polymer battery packs.
Using its integrated high-performance analog peripherals, the BQ27Z746-DEVICE-FW firmware enables the device and measures and maintains an accurate record of available capacity, voltage, current, temperature, and other critical parameters in li-ion or li-polymer batteries, and reports this information to the system host controller. The integrated protection provide safety protection against Over Voltage (OVP), Under Voltage (UVP), Over Current in Charge/Discharge (OCC/OCD), Short Circuit Discharge (SCD), and Battery Sensing Protections (BCP, BCN, BDP and BDN).
SHA-2 authentication, with secure memory for authentication keys, enables identification of genuine battery packs.
BQ27Z746-DEVICE-FW is usable on any previous version of the BQ27Z746 hardware.
Features
Supports pack-side gauging including enhanced state of health (SOH) algorithm

Description:
BQ-BATTERY-PROGRAMMER-SW software development kit (SDK) is a collection of robust software command line tools that assist with the process of programming, testing, or assembling packs that use TI Battery management products. The executables in this software work with the MKST-3P-ALT-EV2300 MKS Technology alternative for EV2300 communications transceiver. The executables work with a single station but can be extended to multiple stations by using additional software and GUI from MKS Technology Inc. . Support for multiple stations is not included in this software.
There are multiple executables in the download, usually one per family of products. Older products such as BQ20xxx and BQ30xxx are also supported. Examples using the C++ programming language API and Python® programming language are provided for custom development.
Requirements:
- Hardware: MKST-3P-ALT-EV2300
- Supported operating systems: Windows (32 and 64 bits)
- Software: Microsoft Visual Studio 2010 C++ Runtime redistributable
Features:
- Collection of command line executables for Windows
- Small executable size with few dependencies
- Fast programming
- Supports BQFS/DFFS and SREC file formats
- Provides C API for custom code development
- Callable from other programs for automation
- Portable design simplifies deployment
- Separately downloadable support software to enable legacy software like BQEVSW and ADVANCED-BQMTESTER to work with MKST-3P-ALT-EV2300
Getting started:
1. Download the software
2. Run the installer
3. The executables, C API and Python API files can be found in the install location
4. Run the command line executable without arguments to get usage help. Refer to Readme.txt in the install folder for more information and how to get help using the command line.
