BQ28Z620 評估模組,適用於單或雙串聯電池芯鋰離子 Impedance Track™ 電池電量計
BQ28Z620EVM-071
概覽
此評估模組 (EVM) 是適用於 BQ28Z620 和 BQ294502 電池管理系統的完整評估系統。EVM 包括一個 BQ28Z620 和 BQ294502 電路模組,和至 Windows® 式 PC 軟體的連結。電路模組包括一個 BQ28Z620 積體電路 (IC)、BQ294502 IC 和其他板載必要元件,以監控預測容量、執行電池芯平衡、監控電路參數,並防止單或雙串聯電池芯鋰離子或鋰聚合物電池組中出現電池過充、過放電、短路和過電流情況。電路模組與電池中的電池芯直接連接。您可透過 EV2400 介面電路板和軟體讀取 BQ28Z620 資料暫存器,為不同電池組配置的晶片組進行編程,記錄循環資料以進一步評估,並使用 I²C 通訊協定針對不同充電和放電條件下的解決方案整體功能性進行評估。

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.
新功能
- Added support for BQ78350 and BQ34Z100

版本資訊
The Texas Instruments BQ28Z620 device is a highly integrated, accurate, 1-series to 2-series cell gas gauge and protection solution, enabling autonomous charger control and cell balancing.
The BQ28Z620-DEVICE-FW enables autonomous charge control through Master Mode I2C broadcasts of charging current and voltage information, eliminating software overhead that is typically incurred by the system’s host controller.
The BQ28Z620-DEVICE-FW device provides a fully integrated pack-based solution with a flash programmable custom reduced instruction-set CPU (RISC), safety protection, and authentication for 1- to 2-series cell Li-ion and Li-polymer battery packs.
The BQ28Z620-DEVICE-FW communicates via an I2C compatible interface and combines an ultra-low-power, high-speed TI BQBMP processor, high-accuracy analog measurement capabilities, integrated flash memory, an array of peripheral and communication ports, an N-CH FET drive, and a SHA-1 Authentication transform responder into a complete, high-performance battery management solution.
Features
- Autonomous battery charging control, using a dedicated MASTER mode I2C interface
- 400-kHz I2C bus communications interface, including a 1.2-V logic level for high-speed programming and data access
- Cell balancing with an internal bypass to optimize battery health
- A high-side protection N-CH FET drive enables serial bus communication during fault conditions
- Programmable protection levels for voltage, current, and temperature
- Support for simultaneous current and voltage sampling
- Supports down to 0.5-mΩ current sense resistor while capable of 1-mA current measurement
- SHA-1 authentication responder for increased battery pack security
