Range-extended electric automobile

Abstract

The invention discloses a range-extended electric automobile using a micro gas turbine generator set. The electric automobile comprises a power electronic converter, a vehicle-mounted charger, an energy storage device, an energy management unit, an overall controller, an electromotor, a speed changer, a micro gas turbine controller, the micro gas turbine generator set and a fuel tank; and under the control of the overall controller, the fuel tank supplies fuel to the micro gas turbine generator set, and the micro gas turbine generator set generates electricity to increase the running mileage of the vehicle. The ranged-extended pure electric automobile reduces the dependence on a charging foundation facility, can adapt to running of high-speed and suburb road conditions better, improves the adaptability of the vehicle, meanwhile diversifies the energy of the vehicle, is favorable for energy safety, and solves the refrigerating and heating problems of the pure electric automobile.

Description

technical field [0001] The invention relates to a range-extended pure electric vehicle, in particular to a range-extended pure electric vehicle which adopts a micro gas turbine generator set to increase the mileage and improve the adaptability of the vehicle. Background technique [0002] Pure electric vehicles use electric motors as drive devices, and are powered by on-board rechargeable batteries or other energy storage devices. They have the advantages of zero emissions, high efficiency, quietness, smooth operation, easy driving and operation, low maintenance costs, and a wide range of required power sources. , so in the existing new energy vehicle technology, it is regarded as the long-term development goal or the ultimate development goal. [0003] The energy storage devices commonly used in pure electric vehicles are battery packs and super capacitor packs. Although the charging and discharging speed of super capacitor packs is fast, its electric energy cannot be store...

AI Technical Summary

Problems solved by technology

Due to the limited driving range and the contradiction between the driving range and the cost and weight of the vehicle, pure electric vehicles can only be used in a small area in the city

Moreover, due to the imperfect charging infrastructure and the lack of breakthrough in ultra-fast charging technology for battery packs, the popularization and mass production of pure electric vehicles have been restricted to a large extent.

[0005] Alternatively, in conventional pure electric vehicles, all energy is derived from energy storage devices, as in Ref.: Essene et al., Modern Electric, Hybrid Electric, and Fuel Cell Vehicles—Rationale, Theory, and Design .Beijing: Mechanical Industry Press, 2008, including the energy required for vehicle cooling and heating, and vehicle cooling and heating, especially cooling energy consumption is very large, so there is a gap between vehicle driving comfort and driving mileage contradiction
