Evaluation and demonstration boards and kits are devices that enable engineers to test and evaluate various technical aspects of design while developing embedded systems. BQ20Z60EVM is one such evaluation board and kit that allows engineers to quickly evaluate and demonstrate the performance and features of the bq20z60 battery gauge, integrated power management, and fuel-gauging functionality. This article focuses on the application field and working principle of the BQ20Z60EVM.

The BQ20Z60EVM is an evaluation board designed to work with the bq20z60 battery gauge. It provides a platform for engineers to evaluate the performance of the bq20z60 battery gauge, integrated power management, and fuel gauging features in a variety of applications. The board offers excellent flexibility and integration up to 16 cells in series. Furthermore, with its integrated model based on voltage, current, and temperature sensing, the BQ20Z60EVM supports both single-ended sensing and multi-ended sensing.

The BQ20Z60EVM includes four LED indicator LEDs that feedback the respective operating mode of the bq20z60, temperature, and low-battery status. Also, the board supports up to 20 applications that make use of the bq20z60\'s device features, including OLED, I2C, Power Path Management, and charging control. It also consists of a universal power supply for input voltages up to 36V, making the product ideal for developing high-end applications.

The working principle of the BQ20Z60EVM evaluation board is based on the bq20z60 battery gauge’s integrated fuel-gauging algorithm. This algorithm is used to continuously monitor the battery cell’s voltage, temperature, current, and SoC (state of charge). The bq20z60 uses this data to estimate the remaining fuel capacity for the battery. The bq20z60 has an on-chip fuel-gauging model, which is used to convert the measured data to the fuel-gauged SoC. It also has an integrated Power Path Management (PPM) simulator, which manages the system’s power supply and helps in efficiently charging the battery.

In addition, the BQ20Z60EVM supports a graphical user interface to facilitate the evaluation of its features. The graphical user interface allows users to view the R-C time constants, relative capacities, fuel usage, temperature sensor accuracy, and other parameters. This helps engineers in tuning the parameters to optimize the performance of the bq20z60 and the integrated power management feature.

The BQ20Z60EVM can be used in a variety of applications, ranging from medical devices to consumer electronics. It can be used to design board-mounted and off-board battery management functions for systems such as cell phones, laptops, and medical devices. It can also be used to evaluate the performance of integrated power management systems for automotive, surveillance, and industrial applications.

The BQ20Z60EVM is an extremely useful tool for engineers in the development of embedded systems. It offers an excellent platform for evaluating and demonstrating the features of the bq20z60 battery gauge, integrated power management, and fuel-gauging features, making it an ideal product for developing high-end applications.
