Trackless trolley car based on wireless charging technology and running control method thereof

Abstract

The invention relates to a trackless trolley car based on a wireless charging technology. Wireless energy receiving ends which are arranged in pairs and underground wireless energy emitting ends matched with the wireless energy receiving ends and continuously laid along a preset running path road sign side by side are added on a traditional structure, the wireless energy receiving ends obtain wireless electric energy from an underground external connection power grid through the underground wireless energy emitting ends, a power electronic converter on the trackless trolley car converts voltage and current, obtained from the wireless energy receiving ends, of wireless electric energy and transmits the voltage and the current to an electromotor to be converted into kinetic energy, and finally, the kinetic energy is transmitted to wheels. The underground external connection power grid is provided with a power controller, a vehicle control unit collects current running information of thetrackless trolley car and feeds the information back to the power controller, and the power controller regulates voltage and current of the underground wireless energy emitting ends according to the feedback information so as to finally control the trackless trolley car to enter in different running conditions. The invention further relates to a running control method of the trackless trolley carbased on the wireless charging technology.

Description

technical field [0001] The invention relates to the technical field of trolleybus control and management, in particular to a trolleybus based on wireless charging technology. Background technique [0002] A trolleybus is a road public transport that is usually powered by an overhead contact grid, driven by an electric motor, and does not rely on a fixed track (a trolleybus is relative to a tram that is driven by electricity and runs on rails or rails). , trackless refers to no rail or rail-like track). Compared with buses, trolleybuses have the advantages of energy saving, environmental protection, comfort and hygiene, and compared with trams, they have the advantages of cheap, flexible, lightweight, and easy to climb. Common trolleybuses are divided into two types, ordinary trolleybuses and dual power source trolleybuses. Ordinary trolleybuses are not equipped with auxiliary power source, and their receiving poles will lose power and stop driving after they are separated ...

AI Technical Summary

Problems solved by technology

[0003] The invention aims at traditional trolleybuses with poor flexibility, easy to cause traffic jams, unable to run off-line for a long time, occupying urban space due to the installation of contact grids and rectifier substations, affecting street clearance and beauty, and easily causing safety hazards due to excessive requirements for drivers. Problems such as hidden dangers provide a trolleybus based on wireless charging technology. By setting special wireless charging devices-wireless energy receiving end and underground wireless energy transmitting end, wireless charging technology is introduced to provide energy for the trolleybus. The overall structure is simple and easy to control. It is convenient and safe, and can realize real-time charging while driving, which greatly improves the charging efficiency. The transmitter device of wireless charging adopts multiple underground wireless energy transmitters connected to the underground external power grid, which are laid side by side and continuously laid, without the need to drive electric cars. Overhead contact with the power grid on the driving path maintains the city's clear space and beauty
