A trolley bus based on wireless charging technology and its operation control method

Abstract

The present invention relates to a trolleybus based on wireless charging technology, which adds pairs of wireless energy receiving terminals and underground wireless energy transmitting terminals that are matched with each wireless energy receiving terminal and laid side by side and continuously along the road signs of the preset driving route on the traditional structure. Each wireless energy receiving end obtains wireless energy from the underground external power grid through each underground wireless energy transmitting end, and then the power electronic converter on the trolleybus converts the voltage and current of the wireless energy obtained from the wireless energy receiving end and transmits it to the motor It is converted into kinetic energy and finally transmitted to the wheels; the underground external power grid is also equipped with a power controller. The vehicle controller collects the current operation information of the trolley bus and feeds it back to the power controller. The power controller regulates the voltage and current of each underground wireless energy transmitter according to the feedback information To finally control the trolleybus into different driving conditions. The invention also relates to an operation control method of the trolley bus based on the wireless charging technology.

Description

technical field [0001] The invention relates to the technical field of trolley bus control and management, in particular to a trolley bus based on wireless charging technology. Background technique [0002] A trolleybus is a road public transportation tool that is usually powered by an overhead contact grid, driven by a motor, and does not rely on a fixed track , trackless means that there is no rail or steel track). Compared with buses, trolleybuses have the advantages of energy saving, environmental protection, comfort and sanitation, and compared with trams, they have the advantages of cheapness, flexibility, light weight, and easy climbing. Common trolleybuses are divided into two types, ordinary trolleybuses and dual power source trolleybuses. Ordinary trolleybuses are not equipped with auxiliary power sources, and their power receiving poles will lose power and stop when they are separated from the overhead contact grid. Poor, and in the absence of dedicated lanes, ...

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
