Structure of idle speed control system for fuel cell hydrogen energy vehicle

Abstract

The invention discloses an idle speed control system structure for a fuel cell hydrogen energy vehicle, which includes a vehicle-mounted fuel cell system, a fuel cell DCDC and an auxiliary energy management system. The air path branch system of the vehicle-mounted fuel cell system includes an air inlet, Air pipe, pipe connector, stacking pipe, electric stack, air outlet pipe and tail discharge port, the air inlet is connected to one end of the air intake pipe, and the other end of the air intake pipe is respectively connected to the inlet pipe through the pipe connector. One end of the stack pipe is connected to one end of the gas outlet pipe, a first electromagnetic valve is installed on the stack inlet pipe, the other end of the stack inlet pipe is connected to the electric stack, a second solenoid valve is installed on the gas outlet pipe, and the gas outlet The other end of the pipeline is connected with the exhaust port. The idle speed control system structure for fuel cell hydrogen energy vehicles is designed with a control and adjustment structure in the air branch system of the vehicle fuel cell system, which is used to stabilize the air pressure surge operating point, divert excess air, and ensure the precise amount of air supply.

Description

technical field [0001] The invention relates to the technical field of fuel cell hydrogen energy vehicles, in particular to the structure of an idle speed control system for fuel cell hydrogen energy vehicles. Background technique [0002] As an important part of new energy vehicles, fuel cell vehicles are the ideal development direction in the future. However, the current fuel cell system has problems such as high idling power and high idling net power output, which requires a large capacity of the auxiliary energy of the whole vehicle, which seriously affects the vehicle cost and body layout of the fuel cell vehicle. Therefore, we propose a fuel cell vehicle. Structure of idle speed control system for battery hydrogen vehicle. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an idle speed control system structure for a fuel cell hydrogen energy vehicle, so as to solve the problems raised in the above background technology. [0004] T...
