基于DM-i技术的EHS电混系统研究

Research on EHS Electric Mixing System Based on DM-I Technology

传统燃油车对于环境的污染问题日益凸显,新能源汽车的发展还远远未达到普及,续航里程不足的问题一直饱受诟病。混合动力汽车兼具两者优势,在动力性和燃油经济性的平衡方面有其特有的优势,比亚迪在2020年发布了DM-i“智慧双模超级混动技术”,在发展至第三代后更是引入了EHS电混系统,这标志着全车电力驱动时代的到来。本文主要介绍了比亚迪EHS电混系统的原理、优势以及对传统机构的影响。

The environmental pollution of traditional fuel vehicles is becoming increasingly prominent,while the development of new energy vehicles is far from reaching popularity,and the problem of insufficient range has been criticized.Hybrid electric vehicles have both advantages and have their own unique advantages in the balance of power performance and fuel economy.BYD released DM-I"Intelligent Dual-mode Super hybrid Technology"in 2020,and introduced EHS electric hybrid system after the development to the third generation,which marks the arrival of the era of all-vehicle electric drive.This paper mainly introduces the principle,advantage and influence of BYD EHS electric hybrid system on traditional institutions.
