Mobile instant charging system for electric vehicle on highway

Abstract

The invention is applicable to the technical field of expressway instant charging, and provides a mobile instant charging system for an electric vehicle on a highway. The system comprises a pluralityof groups of symmetrically arranged photovoltaic power generation devices, a fixing device, a transmission conversion device and a receiving device located on the electric vehicle. Each photovoltaic power generation device comprises a photovoltaic panel, a bottom plate and a plurality of circles of discharge coils, and the discharge coils of the symmetrically arranged photovoltaic power generationdevices are oppositely arranged. The transmission conversion device comprises an inverter and a transformer, the two ends of the inverter are connected with the photovoltaic panels and the transformer respectively, and the transformer is connected with the discharge coils and a social power grid. Therefore, real-time charging of the electric vehicle can be realized, the charging efficiency is improved, the charging queuing time is shortened, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of expressway instant charging, in particular to a mobile instant charging system for expressway electric vehicles. Background technique [0002] As of the end of 2019, China's domestic expressway mileage exceeded 140,000 kilometers, reaching 142,600 kilometers and ranking first in the world. The number of charging cars was 3.1 million, an increase of 1.2 million compared with the end of 2018, a year-on-year increase of 38.7%. According to estimates by the International Energy Agency, by 2030, there will be 125 million electric vehicles in the world, and China and Europe will become the two largest markets. As a new energy vehicle, electric vehicles are the future development trend, but electric vehicles undoubtedly have inherent defects, such as short mileage on a single charge and long waiting times for charging on the way. At present, there are only a few service areas on the expressway with charging pi...

Problems solved by technology

[0006] The above public documents all use wireless transmission technology to realize wireless charging of electric vehicles, but there are the following problems: 1. When wireless charging is performed on electric vehicles during driving, the installation cost is high, and at the same time due to the difference between the discharge and the receiving device There is a long distance between them, which will easily cause the instability of the charging current, and then cause damage to the battery of the electric vehicle; 2. The position of the photovoltaic panel is fixed, and it is impossible to achieve high-efficiency light energy conversion

[0007] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
