Charging highway, underground power supply trolley, electric vehicle, charging system and method

Abstract

The invention discloses a charging road, an underground power supply trolley, an electric vehicle, a charging system and a method, and a short-distance power supply scheme for an electric vehicle through an underground power supply trolley, wherein a power supply track is built in the charging highway to provide power supply for the underground power supply trolley in the whole process When the underground power supply trolley is running on the power supply track, it obtains power from the power supply track and converts it into a voltage and current suitable for charging the electric vehicle, and supplies power to the electric vehicle through wired or wireless power transmission, so that the electric vehicle can be charged while driving. Since the underground power supply trolley can follow the electric vehicle, the charging distance is short and the charging efficiency is high.

Description

technical field [0001] The invention relates to the technical field of vehicle charging, in particular to a charging road, an underground power supply trolley, an electric vehicle, a charging system and a method. Background technique [0002] Due to the limited battery capacity of pure electric vehicles, after a certain mileage, it is necessary to find a charging pile and stop to wait for charging, which limits the convenience of pure electric vehicles. Although the current technology of charging while driving has alleviated this problem to a certain extent, the technology of charging while driving has many limitations based on the existing road structure, a large amount of electric energy is lost during the charging process, and the charging efficiency is not high. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a charging road, an unde...
