An automatic charging method, electric vehicle and charging pile

Abstract

The invention provides an automatic charging method, an electric vehicle and a charging pile, and belongs to the technical field of electric vehicle charging. The automatic charging method comprises the following steps of firstly, controlling the vehicle to drive to an idle charging pile; secondly, sending a first infrared signal containing state information of the charging pile by the charging pile, and judging whether the charging pile is available or not by the vehicle; thirdly, judging whether the charging pile is matched with the vehicle or not by the charging pile, if yes, sending a charging condition having instruction to the vehicle through the infrared signal, and waiting for an adjustment finished instruction and a wifi connection request which are sent by the vehicle; and finally, receiving the adjustment finished instruction by the charging pile, and establishing a physical connection with the vehicle. The automatic charging method, the electric vehicle and the charging pile have the effects that the vehicle and the charging pile carry out information interaction through the infrared signal, the connection is established only when the charging pile is available and is matched with the vehicle, the invalid connection is avoided, and the charging preparation time is effectively shortened; and due to the fact that less information is transmitted at a time by the infrared signal, the information interaction mode has the advantages of small network burden, low channel resource occupancy rate and easiness in implementation.

Description

technical field [0001] The invention relates to an automatic charging method, an electric vehicle and a charging pile, and belongs to the technical field of electric vehicle charging. Background technique [0002] With the rapid development of pure electric vehicle technology and the increase of battery life, new energy vehicles are becoming more and more popular. The charging of pure electric vehicles is a matter of great concern to people, which is related to the popularization and promotion of electric vehicles. [0003] There are mainly two existing automatic charging methods: [0004] 1. When the vehicle enters the charging field, it is directly connected to the wifi network of the charging field, and the vehicle interacts with the background information. The background system assigns the corresponding charging pile to the vehicle and determines the respective charging parameters; then guides the vehicle to the assigned charging pile to charge. [0005] This charging ...
