Abstract: Battery technology is evolving rapidly with growing energy and power densities.While this energy storage device becomes more prominent and ubiquitous in the automotive industry, safety and reliability of the battery system are attracting more attention than ever before.The battery management system (BMS) becomes the key to improving vehicle safety, prolonging battery life, and reducing cost.This project focuses on constructing a test bench for BMS with Hardware-Inthe-Loop (HIL) technique.A battery model that is single-cell-capable and real-timecapable simulates a battery pack's behavior as a series of connected cells.It takes into account the manufacturing differences between cells that cause voltage deviation from the ideal reference voltage.Said model is then implemented into the dSpace mid-size HIL simulator.Several experiments were performed with the virtual battery model to validate prototyped BMS components and BMS software.These components include a module balancing board, a battery controller module, and a battery data logger.These tests indicate it is feasible to validate BMS with HIL techniques, and the developed battery model can reduce the cost of developing BMS software and hardware.
