Hydrogen energy-based hybrid power device for vehicle and method

Abstract

The invention relates to the field of vehicles and discloses a hydrogen energy-based hybrid power device for a vehicle and a use method. The device is composed of two sets of power systems which can independently work, wherein in one set of power system, an engine burning hydrogen fuel is connected with a speed changer, and the speed changer drives front wheels of the vehicle through a connecting shaft; and in another set of power system, hydrogen fuel cells are adopted and combined with a motor and an accumulator, and after the motor is electrified, rear wheels of the vehicle are driven through the connecting shaft. The motor of the hybrid power device disclosed by the invention also has the function of a generator; and when the vehicle brakes, the wheels drive the motor to generate power so that the motor can recover energy when the vehicle brakes. The hybrid power device disclosed by the invention can work in three different running modes, including a city mode, a suburb mode and a high-speed mode, so as to meet the requirement of the vehicle for different power.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a vehicle hybrid power device based on hydrogen energy and a new driving combination method using the device. Background technique [0002] Traditional cars are driven by gasoline or diesel engines, which have the advantages of high power and fast speed. However, with the improvement of environmental protection awareness and the current urban traffic conditions are becoming more and more congested, new energy electric vehicles are also becoming more and more popular. It appears in many places in the consumer market. Electric vehicles have the advantages of low energy consumption and stable driving, but the disadvantages are insufficient power, slow speed and poor endurance. In order to combine the characteristics of the two, a new hybrid vehicle has been developed at this stage, that is, on the basis of keeping the original gasoline engine or diesel engine as the engine, a set of moto...

Problems solved by technology

[0004] For new energy engines, such as natural gas engines or biomass fuel (ethanol, biodiesel, etc.) engines, although they can save oil resources, their efficiency is not as high as that of hybrid power devices. Therefore, it is urgent to develop and design a new energy-based engine at this stage. The hybrid power device can combine the advantages of traditional hybrid power devices and new energy engines to achieve the dual goals of getting rid of dependence on oil resources and improving energy utilization efficiency; moreover, it can be applied to the needs of various road conditions in cities and suburbs
