Super capacitor driven electric automobile motive power device

Abstract

The invention relates to a super capacitor driven electric automobile motive power device, which belongs to the technical field of electric automobile driving and aims at providing the electric automobile motive power device with high specific power and high endurance capability. The super capacitor driven electric automobile motive power device adopts the technical scheme that the output end of a charging module is connected in series with a super capacitor capacitance balance control module and is then connected with the input end of a super capacitor bank, the output end of the super capacitor bank is sequentially connected in series with a direct current-direct current conversion module, a motor controller and a normally closed switch SW1 and is then connected with the power supply end of a direct current motor in a coaxial direct current motor generator set, the motive power output end of the direct current motor is connected with a speed changer, the output end of a direct current generator is connected with the input end of a resonance controller, the output end of the resonance controller is connected in series with a normally open switch SW2 and is then connected with themotor controller, and the output end of the resonance controller is connected in series with a normally open switch SW3 and is then connected with an input port of the super capacitor capacitance balance control module. The super capacitor driven electric automobile motive power device is applicable to the field of electric automobiles.

Description

technical field [0001] The invention relates to a supercapacitor-driven electric vehicle power device, belonging to the technical field of electric vehicle drive. Background technique [0002] With the global energy shortage and the intensification of environmental pollution, energy conservation and emission reduction and low-carbon life have become important tasks for the Chinese government; for the automobile industry, it is mainly to upgrade products, and the national "863 Plan" has specially set up an electric vehicle project. According to the national new energy development plan, hybrid electric vehicles will gradually transition to pure electric vehicles and fuel vehicles. At present, the main bottleneck of the research and development of electric vehicles is that the battery life and specific power as the vehicle power source are different from the expectations of vehicle users. There is a large gap, and there is a certain difficulty in popularizing and using them. ...
