Problems solved by technology
[0002] Affected by factors such as small power battery specific energy, high price, and long charging time, pure electric vehicles cannot meet the needs of various working conditions. After development in recent years, the cruising range of pure electric vehicles has improved. Substantial improvement, enough to meet the needs of short-distance travel in urban areas, but not enough for occasional long-distance travel
[0003] Adding a set of on-board generator sets consisting of "internal combustion engine + generator" to pure electric vehicles, that is, electric vehicles with detachable range-extending devices, solves the "range anxiety" of short driving range of pure electric vehicles, but For most customers, pure electric driving is enough to meet most daily travel needs. In short-distance use in the city, it is rare to use a range extender to generate power to extend the cruising range. Traditional electric vehicles with detachable range extenders are relatively cost-effective. lower

Embodiment Construction
[0019] Referring to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention include the shape, structure, mutual position and connection relationship of each part, the function and working principle of each part, and the manufacturing process of the various components involved. And the method of operation and use, etc., are described in further detail to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.
[0020] Such as figure 1 In the shown embodiment 1, the range extender system is an independent assembly module, which can be separated and combined with pure electric vehicles, and the range extender assembly rental points can be set up at highway intersections and important transportation hubs between cities. During daily short-distance driving in urban areas, the plug-and-play range-extender electr...

The invention discloses an electric automobile with a detachable mileage increasing device. The electric automobile comprises an electric automobile body and the mileage increasing device. The electric automobile body and the mileage increasing device are two separable parts independent of each other. By means of the electric automobile and the control method, the mileage increasing device can beadditionally installed on the electric automobile according to user requirements, and therefore during short-distance driving, the mileage increasing device is detached, and energy waste caused by vehicle weight increasing cannot be caused; and during long-distance driving, the mileage increasing device is arranged, and solving of mileage anxiety and the charging problem in long-distance running of the pure electric automobile is facilitated.
Description
technical field [0001] The invention relates to the field of electric vehicles, in particular to the range-extending technology of electric vehicles. Background technique [0002] Affected by factors such as small power battery specific energy, high price, and long charging time, pure electric vehicles cannot meet the needs of various working conditions. After development in recent years, the cruising range of pure electric vehicles has improved. The substantial improvement is enough to meet the needs of short-distance travel in the urban area, but it does not meet the needs of occasional long-distance driving. [0003] Adding a set of on-board generator sets consisting of "internal combustion engine + generator" to pure electric vehicles, that is, electric vehicles with detachable range-extending devices, solves the "range anxiety" of short driving range of pure electric vehicles, but For most customers, pure electric driving is enough to meet most daily travel needs.
