电池管理系统是保证锂离子电池高效、安全运行的重要手段。在电池管理系统功能中,电池状态估计,特别是荷电状态（state of charge,SOC）估计和健康状态（state of health,SOH）估计至关重要。SOC/SOH不仅与全生命周期内电池安全运行直接相关,也是其他功能有效实现的必要前提。本文围绕模型类电池状态估计方法,综述了国内外在锂离子电池模型构建、SOC及SOH估计方法方面的研究进展;指出了模型类状态估计方法存在的难点和局限,提出了今后研究重点。 相似文献

In this paper, the nitration characteristic of alcohols with mixed acid for the synthesis of energetic materials in a stainless steel microreactor was investigated experimentally. The nitration of iso-octanol with HNO3-H2SO4 mixed acid was chosen as a typical model reaction which involved fast and strong exothermic liquid-liquid heterogeneous reaction process. The influences of mixed acid composition, flow rate, organic/aqueous flow ratio and reaction temperature have been investigated. The results indicated that the reaction could be conducted safely and stably in the microreactor at 25-40°C, which are enhanced compared to 15°C or below for safe operating conditions in the conventional reactors. Moreover, the 98.2% conversion of iso-octanol could be obtained and no by-products were detected in all cases. 相似文献
