Das BQ27Z746EVM-047-Evaluierungsmodul (EVM) ist ein komplettes Evaluierungssystem für den BQ27Z746-Batterie-Manager. Das EVM enthält den BQ27Z746 mit integriertem Schutzschaltkreismodul und einem Link zur Windows® basierten PC-Software. Der integrierte Schaltkreis (IC) BQ27Z746 und alle Onboard-Komponenten dienen zur Überwachung kritischer Zellparameter, zur Vorhersage der Zellkapazität und des Zustands sowie zum Schutz der Zellen vor Überladung, Überentladung, Kurzschluss und Überstrom in Li-Ion- oder Li-Polymer-Akkupacks mit 1 Zelle. Das BQ27Z746EVM kann die BQ27Z746-Datenregister lesen, den BQ27Z746 für verschiedene Gehäusekonfigurationen programmieren, Zyklendaten zur weiteren Evaluierung protokollieren und die Gesamtfunktionalität der Lösung unter verschiedenen Lade- und Entladebedingungen mit dem Kommunikationsprotokoll I2C communication EV2400 und der Software-GUI von bqStudio evaluieren.

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.

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:
