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.
本发明涉及汽车技术领域,尤其涉及一种组合动力系统和商用车,组合动力系统包括柴油机系统、燃料电池系统、进气系统、排气系统和换热系统;进气系统包括进气组件和第一控制阀,所述进气组件分别与大气和所述第一控制阀的第一口连通,所述第一控制阀的第二口与所述柴油机系统连通,所述第一控制阀的第三口与所述燃料电池系统连通;排气系统包括排气组件和第二控制阀,所述排气组件分别与所述第二控制阀的第一排气口和大气连通。本发明能够降低组合动力系统的结构复杂度,便于动力系统协调控制,降低控制的难度,而且可以避免燃料电池在温度较低的工况下启动,提升燃料电池的使用寿命。
