Fuel cell vehicle multi-source controller and control method thereof

Abstract

The invention discloses a fuel cell vehicle multi-source controller and a control method thereof. The fuel cell vehicle multi-source controller functionally comprises communication among a fuel cell engine controller, a vehicle controller and a vehicle intelligent control system; the fuel cell vehicle multi-source controller achieves interaction and control of input information between a fuel cellstack, a cell stack operation monitoring device, a cell stack operation environment control device, a controller body, an upper computer, a fuel cell system and the whole vehicle and the outside. Thefuel cell vehicle multi-source controller and the control method thereof solve the problems that the fuel cell engine controller and the vehicle controller of an existing fuel cell vehicle are independently designed and operated in software and hardware to impede resource integration, to result in resource waste as well as difficulty in cost reduction, to go against comprehensive demand design offunctional safety, electromagnetic compatibility, safety redundancy and intelligent control on chips and systems and to increase the system risk.

Description

technical field [0001] The invention belongs to the field of fuel cell vehicles, and in particular relates to a fuel cell vehicle multi-source controller and a control method. Background technique [0002] The fuel cell engine controller is the brain of the fuel cell engine, controlling the safe and reliable operation of the fuel cell engine. The functions of the fuel cell engine controller mainly include gas management, electricity management, water management, thermal management, communication function and fault diagnosis. [0003] (1) Gas management, hydrogen fuel cells mainly generate electricity through the reaction of hydrogen and oxygen, so gas management plays an important role in the system. Firstly, according to the current set power, the pressure of the reaction gas under the optimal operating state is selected. On the other hand, the reaction gas is continuously consumed, and the change of the flow rate will cause the pressure to fluctuate. In order to ensure t...
