Extended-range trackless rubber-tyred vehicle for mine

Abstract

The invention relates to an extended-range electric anti-explosion trackless rubber-tyred vehicle. The extended-range electric anti-explosion trackless rubber-tyred vehicle comprises a range extender, an AC-DC inverter, a high-voltage distribution box, a DC-AC inverter, a driving motor system and a power battery system, wherein the range extender is electrically connected with the AC-DC inverter; the AC-DC inverter is electrically connected with the high-voltage distribution box; the high-voltage distribution box is electrically connected with the power battery system and the DC-AC inverter respectively; and the DC-AC inverter is electrically connected with the driving motor system. According to the extended-range electric anti-explosion trackless rubber-tyred vehicle, on the basis of a pure electric anti-explosion trackless rubber-tyred vehicle, the range extender is arranged, so that the electric quantity of the battery can be limited, the battery is in a shallow charging and discharging state, the driving range of the whole vehicle is increased, the dispatching difficulty is reduced, the battery loss can be reduced as much as possible, the battery consistency and the safety performance are maintained, and then major potential safety hazards caused by battery problems to coal mine safety production are avoided.

Description

technical field [0001] The invention relates to the technical field of mining vehicles, in particular to an extended-range trackless rubber-tyred vehicle for mines. Background technique [0002] With the decrease of global oil resources and the seriousness of environmental problems, the development of new energy vehicles is an inevitable trend to achieve energy security and environmental harmony. New energy vehicles mainly include pure electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV), extended-range electric vehicles (REEV) and fuel cell vehicles (FCEV). [0003] Among them, the extended-range electric vehicle is a purely electric drive vehicle equipped with ground charging and vehicle power supply functions. The battery capacity of a range-extended electric vehicle is smaller than that of a pure electric vehicle. The energy can come from the battery and the range extender system, which can be charged by the grid or the battery by the range extender system. ...

AI Technical Summary

Problems solved by technology

But it has a big disadvantage: Due to the limitation of explosion-proof requirements, the mass of the whole vehicle is large, so the battery box of the pure electric explosion-proof trackless rubber-tyred vehicle should not be too large, which will lead to insufficient mileage of the whole vehicle

However, the cost of this composite power supply system is too high, and it does not meet the requirements of explosion-proof trackless rubber-tyred vehicles in terms of certain performance advantages
