摘要
针对燃料电池汽车对镍氢动力电池管理系统的要求,本文介绍了一种基于实时操作系统的设计方案。阐述了电池管理系统对电池组的综合评价方法;剩余电量的估算结合了电流积分法,开路电压法和零负载电压法,具有较高的精度;设计了基于高可靠性MC9S12系列单片机的硬件平台,将实时操作系统μC/OS-Ⅱ的移植到该平台上,并设计了基于操作系统的多任务应用软件。通过实际运行证明,该设计方案达到了设计要求,同时提高了系统的实时性和扩展性。
According to the fuel cell vehicles on the nickel-hydrogen battery management system requirements, the paper introduced a design based on real-time operation system and explained the battery＇s quality synthetic evaluation method. The estimation of state-of-charge combines current integration ,open circuit voltage and the zero load voltage,which obtained high precision. It designed hardware platform based on the high-reliability MC9S12 MCU, transplanted the real-time operating system μC/OS-Ⅱ to the platform and designed multi-task applications with it. Through the actual operation, it proved that the designing met the design requirements and improved the system＇s real-time and scalability.
