BQ24747EVM

The BQ2474XEVM family of products is an easy-to-use, high-performance evaluation and demonstration boards and kits for power and battery management systems. BQ2474XEVM products offer complete development and debugging of systems powered by single cells, dual cells, Li-ion, or lead-acid batteries.

The BQ24747EVM evaluation kit features a board to control and validate algorithm behavior for applications with Li-ion battery packs. The board is designed with a complete set of communication, signal conditioning, and control circuitry to ensure accurate data capture and system testing.

The purpose of the BQ24747EVM is to provide an efficient environment for evaluating the performance and operation of the BQ2474X device for Li-ion battery management applications. This evaluation kit includes a single-cell Li-ion battery (not mounted) and provides a graphical user interface (GUI) to communicate with the device and tune its settings.

Operation of the BQ24747EVM is based on two main principles. The first is that of system providing the logic needed to run the board and the software pertaining to operating the board. The second is to provide the balancing of the cells, in order to keep all the cells in a pack or battery system balanced. This is accomplished through the use of the BQ2474X power and battery management IC.

The BQ2474X IC is a single-chip solution for Li-ion battery management systems. It incorporates advanced features such as cell balancing and protection, cell voltage monitoring, and under-voltage protection. The device offers both a simplified hardware design and a simple GUI-based setup interface. It also includes a fast start-up feature that allows the device to be up and running in as little as 10 seconds.

The BQ24747EVM board is designed to specifically provide power to the BQ2474X via a USB connection. This connection is used to transfer the necessary data to configure the BQ2474X for the system being tested. The board also features two plug-and-play solid-state relays, allowing for the connection and disconnection of cell strings during operation.

The GUI is used to control and monitor all parameters related to the system. This includes setting up the cell constants, cell balancing, and other system specific parameters. This allows for the user to adjust the settings for optimum performance in any particular application.

The BQ24747EVM can be used to evaluate the performance of the BQ2474X for single-cell Li-ion battery applications. This evaluation kit provides all the features and functionality necessary to properly test and evaluate the device. With its comprehensive set of features and simple GUI interface, the BQ24747EVM is an excellent evaluation and development board for Li-ion battery management systems.
