Embodiment Construction

[0036] The invention will be further described in detail below in conjunction with the drawings.

[0037] figure 1 It is a cross-sectional view of a flywheel type power generation device of an electric vehicle range extender of the present invention. A flywheel type power generation device of an electric vehicle range extender, which is characterized in:

[0038] Including stator core, armature winding, shaft, flywheel housing, permanent magnet, magnetic soft iron and non-magnetic ferrule.

[0039] Magnetically conductive soft iron and permanent magnets are arranged at intervals and bonded on the inner surface of the flywheel housing. A magnetically conductive soft iron and a permanent magnet form a pair of poles.

[0040] The permanent magnets have multiple pieces and are arc-shaped. All permanent magnets generate the same direction of magnetic field. The arc length of a permanent magnet is greater than 0.3 times the arc length of a pair of poles and less than 0.4 times the arc lengt...

Abstract

A flywheel power generation device for an electric vehicle range extender, characterized in that it includes a stator iron core, an armature winding, a shaft, a flywheel shell, a permanent magnet, a magnetically conductive soft iron and a non-magnetically conductive ferrule, wherein the soft iron is made of The dummy poles and the permanent magnet steels are spaced and bonded on the rotor core to form a pair of poles. The magnetic fields generated by all the permanent magnet magnets are in the same direction, all facing the inside of the rotor or all facing the outside of the rotor; the shape and size of the dummy poles are the same as The permanent magnets are equal; both the dummy poles and the permanent magnets are fixed on the rotor core with non-magnetic ferrules; the permanent magnets and the dummy poles are both rectangular parallelepipeds. The technology of the present invention can effectively reduce the manufacturing cost.

Description

Technical field [0001] The invention relates to a flywheel type power generation device of an electric vehicle range extender, belonging to the technical field of automobile electrical appliances. Background technique [0002] Although pure electric vehicles have the advantages of energy saving, environmental protection, and zero emissions, their driving range is limited. If the electric energy is exhausted before reaching the destination, the car cannot move forward. The range extender is composed of an engine and a generator, which can replenish electric energy to the battery at any time and solve the problem of short driving range of pure electric vehicles. Therefore, it is very necessary to develop a high power density and cost-effective generator for pure electric vehicle range extender. [0003] There have been reports that General Motors' Chevrolet Volt sedan, Chery Automobile's Riich M1 sedan, and Audi A1 e-tron sedan are equipped with range extenders. At present, the ge...
