摘要
针对城市电动公交车加速控制策略不当而导致其输出功率大和电能量消耗高的问题,以某款纯电动公交客车为对象,研究了加速控制曲线与其电能量消耗和最大需求功率之间的关系,并建立Matlab/Simulink整车仿真模型,通过模型对所获得的最优加速控制曲线进行了基于ECE工况的整车加速仿真试验。仿真试验表明,与常用加速控制曲线相比,纯电动公交客车在该最优加速控制曲线作用下,不仅可以降低其单位里程能耗,而且其动力性也能得到保证。
Improper acceleration control strategy always causes high power output and electric energy consumption of city electric bus, to solve this problem, we analyze the relationship between the acceleration control curve with the energy consumption and maximum power on the pure electric transit bus, and build vehicle simulation model in Matlab/Simulink, in which vehicle acceleration simulation test is carried out to verify the optimum acceleration control curve based on ECE driving conditions. The result of the simulation test shows that, compared with the common acceleration control curve, the pure electric transit bus can not only reduce energy consumption per kilometer, but also its power property can be ensured under the optimum acceleration control curve.
