驾驶员的驾驶品质对纯电动汽车能耗的影响

以济南市实际运行的纯电动物流用车为研究对象,分析了不同司机驾车行驶时能耗差别及影响因素,并对车辆加速度、车速、能量回馈、行驶工况及电机过载等因素对纯电动汽车能耗的影响规律进行了测试分析.通过整车控制器对电机过载转矩进行限制、增加超速模式等措施对能耗敏感的驾驶参数进行了优化.试验结果表明,优化后车辆能耗显著降低,有效减小了驾驶员驾驶特性对车辆能耗的影响,与原车相比能耗降低最高可达34.94%. 

The Effect of Driving Manners on EV Energy Consumption

EV energy consumption was affected by driver's driving characteristic and could be lowered by perfect driving manners. The difference of energy consumption driving by different drivers was tested and driving characters of affecting the difference were discussed according to test results of electric vans running in Ji'nan city. Factors influencing EV energy consumption, such as vehicle acceleration, speed, energy recovery, driving cycle and motor overload were tested and analyzed. By vehicle controller, motor torque and over-speed were controlled, and therefore driving parameters to which energy consumption was sensitive were optimized. The test of optimized electric vans is carried out, and results indicated that energy consumption of optimized vans is lowered and insensitive to different drivers. Compared to the original one, energy consumption of optimized vans could be decreased as more as 34.94%.
