    Lithium-Ion batteries are becoming the standard solution as power source for electrical vehicles, but the increasing request of autonomous driving capability imposes stringent safety requirements and asks to fulfil ever growing constraints to achieve the safety specifications. Several considerations must be done about the Safe Operating Area of a battery, that means maintaining the correct levels of voltage, temperature and current, as well as avoiding main power cuts due to system faults. This article proposes an FPGA implementation of a Triple Module Redundancy extension for a conventional BMS. The design of the hardware accelerator is described, the testing set-up is introduced and the results of the experimental validation process are discussed. The FPGA accelerator successfully demonstrates the full functionality and the advantages achievable by its introduction in the Battery Management System (BMS) architecture.

    This paper aims at presenting new solutions for advanced Li-Ion battery management to meet the performance, cost and safety requirements of automotive applications. Emphasis is given to monitoring and controlling the battery temperature, a parameter which dramatically affects the performance, lifetime, and safety of Li-Ion batteries. In addition to this, an innovative battery management architecture is introduced to facilitate the development and integration of advanced battery control algorithms. It exploits the concept of smart cells combined with an FPGA-based centralized unit. The effectiveness of the proposed solutions is shown through hardware-in-the-loop simulations and experimental results.

    The battery is a fundamental component of electric vehicles, which represent a step forward towards sustainable mobility. Lithium chemistry is now acknowledged as the technology of choice for energy storage in electric vehicles. However, several research points are still open. They include the best choice of the cell materials and the development of electronic circuits and algorithms for a more effective battery utilization. This paper initially reviews the most interesting modeling approaches for predicting the battery performance and discusses the demanding requirements and standards that apply to ICs and systems for battery management. Then, a general and flexible architecture for battery management implementation and the main techniques for state-of-charge estimation and charge balancing are reported. Finally, we describe the design and implementation of an innovative BMS, which incorporates an almost fully-integrated active charge equalizer.
