电动汽车续驶里程影响因素分析

Analysis of Influencing Factors of Driving Range for Electric Vehicle

电动汽车因操作便捷、噪声低、节能环保等特点,已成为人们出行的首选交通工具之一。续驶里程作为电动汽车的关键性能之一,广受关注。分析了影响续驶里程的能量流向,然后以能量流向为基础,分析了电动汽车的整车参数、动力电池、电机及其控制器系统、制动能量回收等因素对续驶里程的影响,展望了未来电动汽车续驶里程增加的方向。

Due to factors such as its convenient operation,low noise,energy conservation and environmental protection and so on,the electric vehicle has become one of the preferred transportation tools in a trip for the public.As one of the important performances from the electric vehicle,the driving range has been deeply concerned by the users.The driving energy flowing direction is analyzed,which can affect driving range.And then based on the driving energy flowing direction,interfering factors such as vehicle parameters,the power battery,motor and its controller system,the feedback of braking energy and so on are analyzed.The future direction of increasing driving range for electric vehicle is expected.
