Problems solved by technology

Diesel engine technology is mature, the system is safe and reliable, but there are restrictions on fuel consumption and emission regulations; the pure electric mode of the motor accelerates fast and has zero emissions, but there are problems with cruising range and charging; fuel cells have the advantages of high efficiency, zero emissions, and long mileage , but there are few hydrogenation facilities and the technology is relatively immature
[0003] Due to its own technical bottleneck, a single commercial vehicle power system can no longer meet the needs of multi-scenario vehicle applications. The combination of multiple power systems has gradually become a trend. However, in the prior art, the combination of multiple power systems is usually a variety of single power systems Due to the use of multiple power systems, the system structure is complicated, and the coordinated control between power systems is difficult. In the system of fuel cell and diesel engine combination, the fuel cell sometimes needs to be started at a lower temperature. will shorten the service life of the fuel cell

Abstract

The invention relates to the technical field of automobiles, in particular to a combined power system and a commercial vehicle. The combined power system comprises a diesel engine system, a fuel cell system, a gas inlet system, an exhaust system and a heat exchange system. The gas inlet system comprises a gas inlet assembly and a first control valve, the air inlet assembly communicates with the atmosphere and a first port of a first control valve, a second port of the first control valve communicates with the diesel engine system, and a third port of the first control valve communicates with the fuel cell system. The exhaust system comprises an exhaust assembly and a second control valve, and the exhaust assembly communicates with a first exhaust port of the second control valve and the atmosphere. The structural complexity of the combined power system can be reduced, coordination control of the power system is facilitated, the control difficulty is reduced, the fuel cell can be prevented from being started under the working condition of low temperature, and the service life of a fuel cell is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a combined power system and a commercial vehicle. Background technique [0002] Commercial trucks often pollute the atmosphere due to excessive emissions. With the advancement of environmental governance, the transformation of commercial vehicle power systems has become the general trend. At present, the commercial vehicle power system mainly includes: diesel engine, electric motor, fuel cell, etc. Diesel engine technology is mature, the system is safe and reliable, but there are restrictions on fuel consumption and emission regulations; the pure electric mode of the motor accelerates fast and has zero emissions, but there are problems with cruising range and charging; fuel cells have the advantages of high efficiency, zero emissions, and long mileage , but there are few hydrogenation facilities and the technology is relatively immature. [0003] Due to its own technical bo...
