Public transit trolleybus waiting station quick-charging system

Abstract

The invention discloses a fast charging system at a bus waiting station and belongs to the field of public transportation means. The DC power feeder output from the bus and tram rectification terminal is laid in the underground pipe and led out from each bus and tram waiting station, or the AC power near the bus and tram waiting station is rectified into a DC charging power by a DC rectifier at the waiting station, and the voltage of the DC charging power In the range of 200V-1000V, the charging current is in the range of 20A-500A, the positive and negative output terminals of the DC charging power supply are respectively connected to the positive and negative power supply terminals of the sign type power transmission ring through the charging power control switch, and the power supply status automatic monitor, charging The power control switch and the DC rectifier for the waiting station are arranged inside the billboard-type power box; or the charging power control switch, the automatic power state monitor and the DC rectifier for the waiting station are arranged underground on the billboard. The invention can cancel the special feeder wires for trolleybuses on urban roads, improve the mobility of public transport trams, and is beneficial to the rational layout of public transport tram routes.

Description

technical field [0001] The invention relates to a fast charging system, in particular to a fast charging system at a bus waiting station, belonging to the field of public transportation means. Background technique [0002] Trolleybus has become one of the important tools of urban public transportation due to its advantages of low noise, zero emission and good economy. However, due to the visual pollution, poor mobility, and unreasonable bus layout brought by the overhead power supply contact line of the trolleybus, the development of the trolleybus is also greatly restricted. Buses powered by supercapacitors or batteries have become an alternative to trolleybuses, trams, and other urban public transport trams due to their advantages such as no feeder wires, good mobility, and convenient system maintenance. [0003] Through literature search, it is found that the Chinese patent authorization announcement number is: CN 2406858Y. The trolleybus disclosed in this patent uses a ...

AI Technical Summary

Problems solved by technology

The problem with this approach is that there are still overhead power feeders, which doesn't fully address issues like visual pollution and poor maneuverability

At present, the charging of supercapacitors or batteries on bus trams without overhead power supply lines under development is carried out at the starting station or terminal station of the bus line. The supercapacitor or battery has a large capacity, large volume, and heavy weight, which leads to an increase in the weight of the bus, an increase in relative energy consumption, a decrease in the effective space, and a decrease in the passenger capacity. The substantial increase in cost is not conducive to promotion
