三元锂电池在新能源汽车上的设计与应用

Design and Application of Ternary Lithium Battery in New Energy Vehicles

新能源汽车是汽车行业发展的大势趋,我国当前对燃料电池(FCV)汽车和纯电动(EV)汽车给予更多政策上的倾斜。现阶段新能源车的续航里程在大幅度地提升,与之息息相关的就是电池技术的提升。作为解决方案之一的锂电池,具有电池能量密度大、没有记忆效应、循环性能优越、使用寿命长诸多优点,是未来发展的一大趋势。以卡罗拉双擎E+车型为例,论述动力三元锂电池在乘用车上的设计和具体应用,为后续的PHEV车型动力电池的设计提供参考。

New energy vehicles are the general trend of the development of the automobile industry.At present,China gives more preferential policies to fuel cell(FCV)vehicles and pure electric(EV)vehicles.At this stage,the range of new energy vehicles is greatly improved,which is closely related to the improvement of battery technology.As one of the solutions,lithium battery has many advantages,such as high energy density,no memory effect,excellent cycle performance and long service life,which is a major trend of future development.This paper takes Carola dual engine E+vehicle as an example,discusses the design and specific application of power ternary lithium battery in passenger cars,and provides reference for the design of power battery of PHEV.
