Running electrical vehicle wireless charging device based on solar photovoltaic power supply

Abstract

A running electrical vehicle wireless charging device based on solar photovoltaic power supply comprises a photovoltaic array, a solar controller, a photovoltaic energy storage battery, a direct-current junction station, a primary converter, a wireless charging emitting end, a vehicle-mounted wireless charging receiving end, a secondary converter, a vehicle-mounted charging and discharging super-capacitor module, a vehicle-mounted charging controller, a vehicle-mounted storage battery and a highway carriageway. The photovoltaic array is connected with the direct-current junction station, the direct-current junction station is connected with the photovoltaic energy storage battery and the primary converter, after high-frequency inversion conversion is carried out on photovoltaic direct currents through the primary converter, alternating currents are transmitted to the wireless charging emitting end, pulse electromagnetic energy sent by the wireless charging emitting end can be received by the vehicle-mounted wireless charging receiving end and is stored in the vehicle-mounted charging and discharging super-capacitor module in a flash mode, charges obtained by the super-capacitor module can pass through the secondary converter and a vehicle-mounted charger to charge the vehicle-mounted storage battery, and the whole charging process of an electric vehicle is achieved.

Description

technical field [0001] The invention relates to an automobile charger, in particular to a wireless charging device for electric automobiles powered by solar photovoltaics. Background technique [0002] Since scientists revealed the phenomenon of electromagnetic induction, the transmission of electric energy is mainly carried out by direct contact of wires. The charging of electrical equipment is generally carried out through plugs and sockets, but when charging with high power, there is a risk of high-voltage electric shock in this charging method. Due to the existence of friction and wear, it has a certain impact on the safety and reliability of high-voltage power systems and shortens the service life of power equipment. When powering sports equipment, such as trams in urban traffic, generally use Power is supplied by sliding contact, which has disadvantages such as sliding wear, contact sparks, carbon deposits, and unsafe exposed conductors. [0003] Today, a...
