A dynamic wireless charging automatic alignment system and its control method based on the electric bus parking process

Abstract

The invention provides a dynamic wireless charging automatic alignment system based on the electric bus stopping process and a controlling method thereof. Automatic alignment of vehicle-mounted wireless charging equipment with a ground charging coil group is achieved in the dynamic processes of pulling in a station, stopping and pulling out the station of an electric bus, and high-efficiency wireless charging is conducted. Through receiving and transmitting signals of a high-frequency coil group, a motor is controlled after the signals are analyzed through a single chip computer to drive the vehicle-mounted wireless charging equipment to move, automatic alignment of the wireless charging equipment is achieved, wireless charging with the maximum efficiency is pursued, the cruising ability is further improved, the number of batteries carried is reduced, and the vehicle body is lightweight. At the same time, through a pulling-in and pulling-out sensing coil group, the single chip computerconducts calculating and analysis and controls timely opening and closing of the alignment system, energy saving and environmental protection are achieved, and safety of the charging system is improved.

Description

technical field [0001] The invention belongs to the field of wireless charging of electric vehicles, and in particular relates to a dynamic wireless charging automatic alignment system and a control method thereof based on the parking process of an electric bus. Background technique [0002] With the development of science and technology, environmentally friendly and energy-saving electric vehicles have attracted more and more attention from the society due to their advantages such as environmental friendliness, low noise, and high energy utilization efficiency. Electric buses mainly refer to pure electric buses, all of which use electric energy to drive. This type of product has low noise, high driving stability, and achieves zero emissions. Electric bus is the new generation of electric vehicle technology proposed by the national 863 plan as the main direction of my country's automobile technology innovation. The commanding heights of a generation of electric vehicle indus...
