Development of a Distributed Battery Management System with Active Balancing for Electric Vehicles
Main Article Content
Abstract
This work presents the development of a distributed battery management system with active balancing for electric vehicles. A modular architecture was implemented consisting of a master module and multiple slave modules communicating via an RS-485 bus. The slaves use isolated flyback DC-DC converters for cell balancing. Simulations validated the system's functionality which was further tested experimentally. The results demonstrated correct and reliable operation in transferring power between the LiFePO4 cell pack and the lead-acid service battery in both directions. However, some unwanted noise was observed during switching which was successfully minimized using RC snubbers. Overall, the developed system allows effective cell balancing to improve the battery pack lifetime.
