製品概要

概要

The STEVAL-L99615C is an evaluation kit composed of an expansion board containing the L9961 IC device for battery pack monitoring solution, and the NUCLEO-G071RB STM32 Nucleo-64 development board.

The evaluation kit demonstrates the performance and the ease of integration of ST technology for BMS applications.

The STEVAL-L99615C exploits the characteristics of the L9961 able to monitor up to five Li-ion battery cells in series configuration, communicating with the STM32G071RB microcontroller, through an I²C interface.

The expansion board has been specifically developed to be stacked on the NUCLEO-G071RB development board through the morpho connectors. It embeds a power connector for the connection to a 5-cell battery pack or, alternatively to an external power supply to emulate the battery pack.

A dedicated software package containing firmware program for the STM32G071RB microcontroller and a GUI for the PC (STSW-L99615C), has been released to permit the users to take benefit from the demonstration.

Major characteristics described by STSW-L99615C are: cell voltage and stack voltage monitoring, stack current monitoring, temperature conversion via external NTC, OV, and UV thresholds management.
