Unmanned electric vehicle automatic charging method and electric vehicle

Abstract

The invention provides an unmanned electric vehicle automatic charging method. The method comprises the following steps that an unmanned driving route for an electric vehicle is set, then an electricquantity detection module arranged on the electric vehicle checks the residual electricity quantity of a vehicle-mounted battery pack and starts a charging station matching module when the residual electric quantity cannot meet the mileage of the set driving route, and the charging station matching module is used for searching for charging stations along the driving route according to the set driving route and selecting the charging station with the optimal distance; each charging station comprises at least one charging pile, each charging pile can send out an available signal to a nearby unmanned electric vehicle which needs to be charged when the charging pile is idle, the electric vehicle sends an access signal to a certain idle charging pile, and the electric vehicle drives into a parking position corresponding to the charging pile after the charging protocol is reached; and after the charging pile confirms that the electric vehicle reaches the designated parking position, a confirmation signal is sent to the electric vehicle, the electric vehicle automatically enters in P gear and opens a charging interface to enable a charging plug of the charging pile to be connected.

Description

【Technical field】 [0001] The invention belongs to the technical field of charging, and in particular relates to an automatic charging method for an unmanned electric vehicle and the electric vehicle. 【Background technique】 [0002] With the advancement of science and technology, electric vehicles with power batteries as energy sources have been vigorously promoted and applied by many governments because of their advantages such as no exhaust gas emission, no pollution to the environment, high energy utilization rate, relatively simple structure, and low noise. In addition, intelligent vehicles and unmanned driving technologies are becoming more and more mature. [0003] At present, the application of unmanned driving technology to the field of electric vehicles cannot realize the automatic charging of unmanned electric vehicles, and the charging still needs to be done manually. Therefore, the reliability of charging is limited by the professional quality of the charging pers...

Problems solved by technology

[0003] At present, the application of unmanned driving technology to the field of electric vehicles cannot realize the automatic charging of unmanned electric vehicles, and the charging still needs to be done manually. Therefore, the reliability of charging is limited by the professional quality of the charging personnel, and the probability of accidents is unpredictable. Large, and can not achieve 24h charging

In addition, the number of existing charging stations is relatively small, it is difficult to find, and it is impossible to match the charging station with the best distance according to the travel route and remaining power of the electric vehicle, which greatly hinders the user experience of electric vehicles and driverless technology. and long-term development
