组建PHEV车队,由不同通勤距离的用户使用,进行了为期1年的道路试验。对试验结果进行分析后发现:PHEV能耗受行驶工况等影响,与充电行驶里程相关,并且对环境温度极其敏感,除空调等因素外,试验车辆自身的一些特点——在CD模式下,发动机适当参与驱动以及必要的暖机等,使其在低温环境下的能耗明显增加,主要体现在CD距离缩短,CD模式和CS模式燃油消耗量增加3个方面。在使用中应尽量提高充电频率,提高PHEV运行在CD模式下的行驶里程比例,更多地依赖从电网获得电能减少燃油消耗。
The PHEV fleet was set up and used by users with different commuting distances for a one-year road test. After analyzing the test results, it is found that the energy consumption of PHEV is affected by driving conditions and is related to charging mileage and is extremely sensitive to the ambient temperature. Besides the air conditioning and other factors, some features of the vehicle are tested - in CD mode, Engine proper participation in the drive and the necessary warm-up, so that its energy consumption increased significantly in low temperature environment, mainly in the shorten the CD distance, CD mode and CS mode fuel consumption increased by three aspects. Should be used in the charging frequency should be increased to improve PHEV run in CD mode mileage ratio, more dependent on the grid to obtain electricity to reduce fuel consumption.
