Integrated five-in-one system of hydrogen fuel cell vehicle

Abstract

The invention discloses an integrated five-in-one system of a hydrogen fuel cell vehicle, which comprises a driving motor, a speed reducer, a galvanic pile air compression motor and a control panel which are integrated into a whole, and a driving motor controller and a galvanic pile air compression motor controller are integrated on the control panel. Originally separated parts (the galvanic pileair compressor controller, the motor controller, the galvanic pile air compression motor, the driving motor and the speed reducer) are integrated into one part, so that the functional devices can be arranged in a limited arrangement space, the arrangement space of the hydrogen fuel cell vehicle is saved, five-in-one high integration is realized. High-low voltage wiring harness loops are effectively reduced, meanwhile, the overall weight is greatly reduced, the number of ECU parts and high-voltage wiring harnesses of the whole vehicle is reduced, the production design management cost is reduced, the assembly efficiency is improved, and the energy loss, caused by the weight, of the hydrogen fuel cell vehicle is reduced.

Description

technical field [0001] The invention relates to the technical field of integrated systems for hydrogen fuel cell vehicles, in particular to an integrated five-in-one system for hydrogen fuel cell vehicles. Background technique [0002] As hydrogen fuel cell vehicles gradually begin large-scale application and production, how to reduce vehicle energy consumption, improve product layout and improve vehicle NVH performance is one of the great challenges hydrogen fuel cell vehicles are facing. It is the main solution currently applied. [0003] In order to improve the NVH performance of hydrogen fuel cell vehicles, the layout of the whole vehicle will arrange the stack air compressor and the drive motor system together. However, the separate arrangement requires a larger layout space and is heavier, so an integrated The five-in-one solution of stack air compressor controller, stack air compressor motor, drive motor controller, drive motor and reducer has become inevitable.
