The invention discloses an experimental platform for fault diagnosis of extended-range electric vehicles, which comprises a platform base, the lower surface of the platform base is fixedly connected with a fixing device, and the lower surface of the platform base is fixedly connected with vertical and horizontal movable Sliding seat, the upper surface of the platform base is fixedly connected with an adjustable sliding seat, the upper side of the adjustable sliding seat is plugged with a liftable adjustment device, and the top of the liftable adjustment device is fixedly connected with a range extender base . Fault generating devices can be mainly divided into four categories: simulation of engine misfire fault, simulation of misalignment fault, simulation of inter-turn short circuit fault of generator components, simulation of different types of coupling faults. As one of the most important devices in the range extender experimental platform, the fault generating device can simulate the faults that may occur during the actual operation of the range extender electric vehicle, and analyze the faults through artificial setting, which can be used for the range extender electric vehicle. Car fault diagnosis provides a certain basis.
Description
technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a fault diagnosis experiment platform for range-extended electric vehicles. Background technique [0002] In order to cope with the tense situation of energy shortage and environmental pollution, electric vehicles have become a research hotspot due to their advantages of energy saving and environmental protection. However, insufficient power, short cruising range, low battery density, and long charging time all restrict the development of electric vehicles. Hybrid vehicles greatly improve the power performance and change the operation mode of traditional vehicles. However, the energy saving and emission are far lower than that of electric vehicles. Extended-range electric vehicles are superior to pure electric vehicles in terms of cruising range and lower than hybrid vehicles in terms of energy saving and emissions. They have the advantages of economy, environmental p...
