A small electric vehicle with extended range and its control method

Abstract

The invention discloses a small-sized extended-range electric vehicle. The small-sized extended-range electric vehicle comprises a driving motor (15) and a range extender system (10), wherein the range extender system (10) is provided with an engine (25) which is a naturally aspirated in-line two-cylinder gasoline engine, and the discharge capacity of the engine (25) ranges from 0.6 L to 1.0 L. The invention further discloses a control method of the small-sized extended-range electric vehicle. By adoption of the technical scheme, the arrangement compactness, safety and convenience of the vehicle are improved, the weight of the small vehicle is reduced, the dynamic property and driving mileage of the vehicle are increased, the fuel efficiency is improved, and the overall fuel consumption is reduced; meanwhile, the whole vehicle has the advantages of being safe in running and charging and low in vibration and noise; the structural layout of the whole vehicle is convenient to implement and compact, gear shifting is simple, a driver can drive the vehicle easily, and the technical scheme is particularly suitable for the field of small-sized electric vehicles.

Description

technical field [0001] The invention belongs to the technical field of new energy electric vehicles. Specifically, the present invention relates to a more compact vehicle layout scheme for an extended-range small electric vehicle. In addition, the present invention also relates to a control method of the small electric vehicle. Background technique [0002] With the advancement of science and technology, the increasing scarcity of oil resources and the improvement of public awareness of environmental protection, electric vehicles have attracted more and more attention. In recent years, electric vehicles have achieved significant development, but the energy density of batteries is not high, and battery life is short, resulting in short mileage, which is a major bottleneck in the current market promotion. [0003] In order to solve the problem of short cruising range of electric vehicles, various extended-range electric vehicles have emerged as the times require. The range-...
