Abstract

The invention discloses a pure electric vehicle range-extension device. The pure electric vehicle range-extension device comprises a voltage and current collector, an upper computer, an oil-fed generator assembly, a travelling bearing mechanism, a traction mechanism and a conduction cable; the voltage and current collector is in communication with a range-extended vehicle, and the upper computer controls an oil-fed generator to generate electric energy according to the demands of the range-extended vehicle; the electric energy is transmitted to the range-extended vehicle through the conductioncable for driving of the range-extended vehicle; the voltage and current collector, the oil-fed generator, the upper computer and the conduction cable are arranged on the travelling bearing mechanism; and the traction mechanism is connected to the range-extended vehicle and the oil-fed generator, and the oil-fed generator and the range-extended vehicle synchronously travel and are separated. Theproblems that an existing pure electric vehicle is short in driving range and high in cost are solved.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to a range extender for pure electric vehicles. Background technique [0002] Due to the requirements of the automobile industry regulations on the total weight and length of the car itself, as well as the vehicle shape and comfort; combined with the current specific energy and specific volume technical status of the battery, pure electric vehicles generally have the disadvantage of less driving mileage . [0003] In the existing range-extending technology of electric vehicles, hybrid drive schemes and self-contained power generation system schemes are generally adopted to increase the mileage of vehicles. [0004] After research, it is found that the hybrid drive scheme and self-contained power generation system scheme have at least the following defects: [0005] The hybrid drive scheme has a short mileage in the pure electric state and has the lowest comprehensive e...
