Abstract

The invention discloses a hybrid power driving system comprising a generator (1) and a supercapacitor (3). A fuel gas engine serves as a power source of the generator. The generator is connected with the input end of a motor controller (5) through a rectification unit (2). The output end of the motor controller is connected with a traction motor (6). The supercapacitor is in parallel connection between the rectification unit and the motor controller through a bi-directional DC/DC convertor (4). A brake resistance unit (7) is further in parallel connection between the rectification unit and the motor controller. According to the system, fuel gas and capacitance hybrid power driving can be achieved simply and economically to obtain the optimal economic benefit. The invention further discloses a vehicle using the hybrid power driving system and a working process of the supercapacitor in the system.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a gas engine and supercapacitor hybrid drive control technology. Background technique [0002] Electric drive mining dump trucks are the main transportation equipment for large-scale open-pit mines. During actual use, mining dump trucks may cause diesel engine damage in working conditions such as no-load, heavy-load flat land cruising, downhill, deceleration braking, loading and unloading, and idling waiting. The load rate often works in low load conditions. It is estimated that the average load rate of the electric wheel mine truck engine is about 40%, especially when idling and waiting, all the energy emitted by the engine is consumed on mechanical losses, and the efficiency is zero, which objectively causes the engine fuel consumption of the mine dump truck to be reduced. Poor economy, low efficiency, high energy consumption and large emissions. However, with the increasingly serious...
