Traction method used during power shortage of electric vehicle

Abstract

The invention aims to overcome the defects in the prior art and fully utilize the own characteristics of electric vehicles, and provides a traction method used during power shortage of an electric vehicle. The traction method is safe and convenient to use and saves time and labor. The traction method used during power shortage of the electric vehicle uses a traction cable, a power transmission cable and a signal transmission cable and comprises the following steps that S001, when a rescue vehicle finds the power shortage vehicle, the rescue vehicle is connected with the power shortage vehiclethrough the traction cable, the power transmission cable and the signal transmission cable; S002, the rescue vehicle transmits power to the power shortage vehicle through the power transmission cable.By means of the method, resource and time waste caused by a traditional vehicle traction method is avoided, and the safety of the rescue vehicle, the power shortage vehicle and surrounding vehicles in the traction process is also ensured.

Description

technical field [0001] The invention relates to the field of vehicle traction, in particular to a traction method for an electric vehicle when there is a power shortage. Background technique [0002] In recent years, new energy vehicles have developed rapidly, among which pure electric vehicles are the fastest growing and most promising. A pure electric vehicle refers to a vehicle powered by an on-board power supply and driven by a motor to drive the wheels. In today's society, in order to save energy and protect the environment, the bus rental system using pure electric vehicles has also begun to develop. Come on. [0003] At present, in the face of the state that the vehicle needs to be towed, the existing technology often adopts a rescue vehicle to be directly loaded for towing according to a conventional processing method. These treatments are suitable for ordinary diesel locomotives or gasoline-electric hybrid vehicles. But in the face of pure electric vehicles need...

AI Technical Summary

Problems solved by technology

But in the face of pure electric vehicles needing rescue due to lack of electricity, if these conventional methods are used directly, public resources and time will be wasted, because the electric vehicle is not really faulty at this time, and it only needs to be supplemented with a certain amount of electricity, or use It can quickly and conveniently reach the nearest charging station, and the electric vehicle that is short of power can be restored to a state that can be used normally

In addition, because the traditional towing method takes up a certain amount of time and space, when towing in complex road conditions, it is often prone to secondary accidents and endangers traffic safety.
