Abstract

The invention discloses a distance increase device of an electric vehicle, which belongs to the field of electric vehicles. The distance increase device consists of a switch control device and a distance increase component, wherein the switch control device comprises a first switch, a second switch, a switch controller and a current sensor, a power source of a vehicle provides power source for a motor controller through the first switch, the distance increase component provides the power source for the motor controller through the second switch, and when the distance increase component provides the power source for the motor controller, the breakover of the second switch is controlled by the switch controller, so that the switch of the power source is realized, and the running distance is increased. In addition, when the current sensor detects that the power source provided by the distance increase component is successfully received by the motor controller, the first switch is controlled by the switch controller to be disconnected, sudden power failure in a power source switching process is prevented, and the running safety of the vehicle is improved; and when the first switch is disconnected, the distance increase component only needs to provide the power source for the motor controller, the power source of the vehicle does not need to be charged, and the running mileage of the electric vehicle is further increased.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a range extender for electric vehicles. Background technique [0002] Currently, there are various drawbacks in the fuel generator vehicles commonly used, such as low energy utilization rate and serious pollution. With people's awareness of energy saving and environmental protection, electric vehicles are getting more and more attention. However, limited by the storage capacity of batteries, compared with fuel vehicles, pure electric vehicles have the disadvantages of short mileage and high cost, which brings great inconvenience to people's travel. Contents of the invention [0003] The object of the present invention is to provide a range extender for an electric vehicle, which not only increases the mileage of the electric vehicle, but also has a relatively simple circuit and low manufacturing cost. [0004] In order to achieve the above object, the present invention provides a r...
