摘要
电动汽车以其高效率、低排放等优点受到越来越多的重视。由于二次电池储存能量的有限性,因此电机驱动系统的效率是增加续驶里程,降低成本的关键之一。对电动汽车电机驱动系统最大效率控制进行了综述。从电机驱动系统着手,首先分析了最大效率控制的工作原理,对其实现方法和特点进行了重点阐述,并指出了最大的效率控制实现的条件。
Electric vehicles（EVs） have engaged our att,-ntion on because of its high efficiency and low emission. Due to the limitation of energy source in secondary batteries ,efficiency of the motor drive system is the one of the key to extend drive range and reduce the cost. This paper synthesized efficiency optimized control （EOC）of EVs＇drive system. Motor driving system of EVs are compared firstly,and then the principle of EOC is described. Especially, the two type of implement methods of EOC and their characteristics are emphasized, respectively. Finally,conditions of EOC are also proposed.
