纯电动轿车用锂离子电池系统技术研究

Pure Electric Cars Using Lithium-ion Battery System Technology Research

以某款纯电动轿车为研究对象,研究了电池包与整车的匹配集成及电池系统内部布置集成、设计了电池系统的热管理控制策略、开发了电池系统安全技术,并利用CFD对电池系统温升进行了分析设计,研究结果表明,电池系统本部布置合理,电池系统安全性高,系统冷却及控制系统合理。

In a pure electric cars as the research object, the research of battery pack and vehicle matching integration, integration and battery system interior layout design the battery thermal management of system control strategy, developed a battery system security technology, and by using CFD analyses the temperature rise of the battery system design, the results show that the battery system based layout reasonable, battery system has high security, cooling system and control system is reasonable.
