Active Battery Management System (BMS) Development

Project Date: Ongoing

This project focuses on developing an advanced, low-cost Battery Management System (BMS) for energy storage solutions, particularly for electric vehicles and renewable energy applications.

The new BMS design addresses previous limitations by introducing efficient charge redistribution, constant monitoring, and active balancing to ensure safety and optimize performance.

Key Features and Innovations

Pack-to-Cell Balancing: Ensures even charge distribution across all cells.

Cell Monitoring: Utilizes differential op-amps for accurate, safe monitoring of individual cells.

Efficient Communication: Integrates CANBus, I2C, and UART for robust system communication.
