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

Abstract

The trolley bus transit stop quick charging system is characterized by that the D.C. power wire outputted by trolley bus commutating general station is laid in the underground pipeline, and can be led out from every transit stop or the A.C power source nearby trolley bus transit stop can be commutated into D.C. charging power source by means of D.C. commutator for transit stop, the voltage of D.:C. charging power source is 200V-1000V, and charging current is 20A-500A, the positive and negative output ends of D.C. charging power source can be respectively connected with positive and negative power source ends of indicator board type transmission ring by means of charging power source control switch, and the power source automatic monitor, charging power source control switch and trasit stop D.C. commutator are placed in the interior of signboard type power source box.

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 number is: 99230060.6. The trolley bus disclosed in this patent uses a battery as an auxiliary pow...
