摘要：

为控制新能源汽车电池耗电量，并对其电能消耗行为进行原位分析，针对新能源汽车电池的在线监测与原位分析技术展开研究。完善动力锂电池组结构模型，根据汽车电池的热耦合特性，推导监测核函数，实现新能源汽车电池的在线监测。在此基础上，确定汽车电池的电极材料，并分别从表征特性、拉曼光谱两个角度，对其电池元件的原位特性进行研究。

关键词: 新能源汽车, 在线监测, 原位分析, 热耦合特性, 表征特性, 拉曼光谱

Abstract:

To control the power consumption of new energy vehicle batteries and conduct in-situ analysis of their energy consumption behavior, research is conducted on online monitoring and in-situ analysis technologies for new energy vehicle batteries. Improve the structural model of power lithium battery packs, derive monitoring kernel functions based on the thermal coupling characteristics of automotive batteries, and achieve online monitoring of new energy vehicle batteries. On this basis, the electrode materials for automotive batteries were determined, and the in-situ characteristics of their battery components were studied from the perspectives of characterization characteristics and Raman spectroscopy.

Key words: new energy vehicles, on-line monitoring, in situ analysis, thermal coupling characteristics, characterization characteristics, Raman spectrum
