Problems solved by technology

Therefore, the function of the traditional internal combustion engine test bench is basically limited to the test and assessment of the engine's mechanical power, fuel consumption, etc.
However, the new type of vehicle with fuel cells as the main power source has a power system that is significantly different from traditional vehicles in terms of form and function. Its power

Embodiment Construction

[0022] Referring to the accompanying drawings, specific embodiments of the present invention will be described in detail.

[0023] Such as figure 1 , the system function structure diagram of the experimental research system of the fuel cell hybrid power system is given. The whole system can be divided into four subsystems: fuel cell hybrid system, fuel cell hybrid test system, fuel cell hybrid test control system and fuel cell hybrid load system. The direction of the arrows in the figure indicates the flow relationship of information interaction between various systems. Such as figure 1 As shown, the control commands (mainly accelerator pedal signals, brake pedal signals, etc.) composed of various driving manipulation behaviors of the "driver" are sent to the fuel cell hybrid test control system. The fuel cell hybrid test control system is equivalent to the vehicle controller (VCU) of the fuel cell vehicle, which is a CAN network-based control system. It receives various c...

Abstract

Experimental investigation system of fuel cell hybrid power system includes loading system, experimental control system, hybrid power system and test system. The loading system simulates road condition, dynamics characteristics of car body, and drivers. Combining with operation conditions of each part in the system, the experimental control system converts each condition to control command for each part, controls and adjusts running condition. The hybrid power system is subject to the disclosed experimental investigation system investigates. The test system collects, monitors and records operation conditions of other three systems. The invention carries out experimental investigation functions of testing and checking fuel cell hybrid power system, that traditional testing system for internal combustion engine does not perform. Thus, the invention possesses high innovation.

Description

technical field [0001] The invention relates to a fuel cell hybrid power system test and research system, and the system relates to the research and development field of power system integration technology of fuel cell vehicles. Background technique [0002] Fuel cell vehicle is a new energy vehicle. Compared with traditional internal combustion engine vehicles, it has excellent working performance of energy saving, environmental protection and quiet operation, which has become a hot spot in the current new generation of vehicle research and development technology. The national "Tenth Five-Year Plan" 863 major project for electric vehicles has set up sub-projects for fuel cell cars and fuel cell city buses. The research and development of fuel cell vehicles has become a major measure to promote the leapfrog development of my country's automobile industry. The integration technology of fuel cell hybrid power system is one of the key technologies in the field of fuel cell vehi...
