Battery Management System
Our configurable battery management system is engineered to offer a complete solution for monitoring high voltage battery packs. It consist of a Master board based on an STM32
Designing a Battery Management System (BMS) with STM32 involves defining the BMS requirements, choosing the appropriate microcontroller, designing the hardware, writing the firmware, testing, debugging, and deploying the BMS.
Here's an example code for a basic BMS with STM32 for a 3-cell battery pack: Note: This code initializes the necessary GPIO pins and ADC channels for voltage, current, and temperature sensing. It then reads the voltage levels of each cell in the battery pack, calculates the battery voltage, and checks for overvoltage and under-voltage conditions.
Battery packs are at the core of all cordless equipment, and they all include battery management systems (BMS) to interface with chargers and power tools to maintain proper operating conditions. The BMS monitors each battery cell and total battery pack voltage and operating current to ensure safe and reliable operation.
STMicroelectronics provides a range of integrated circuits allowing to build up battery management systems for Lithium-Ion batteries. ST's BMS solution demonstrates the benefits of a battery management system for automotive applications, based on the L9963E battery monitoring and protection IC and ST's automotive MCUs.
