Description
Technical field
The present invention relates to a kind of car performance test system, especially relate to a kind of dynamic performance testing system for Fuel Cell Vehicle Powertrain.
Background technology
At present, associated fuel cell automobile dynamic system also high less than integrated level is both at home and abroad integrated, the special equipment of debugging and testing, integrated, the coupling of Fuel Cell Vehicle Powertrain and the needs of the test such as reliability, permanance, environmental suitability and security can not be met, make a concrete analysis of as follows:
A, FC pile critical equipment equipment technology status at home and abroad is analyzed:
The domestic fuel pile also do not developed for automobile-used condition simulates vehicle-mounted variable working condition test platform at present, is only carry out record to fuel cell actual operation parameters.Many companies are proposed the fuel battery test platform of oneself in the world, the Hydrogenics company of the U.S. and National Instruments (National Instruments) are proposed some software and hardware test products, can compatible pluralities of fuel battery.Greenlight company of Canada, U.S. Fuel CellTechnologies (FCT), German FuelCon company is all proposed oneself fuel cell testing device.Domestic corporation is also proposed the fuel battery test system for different size pile, but general precision is not high.As the patent No. be 200810036146.6 patent of invention and the patent No. be the utility model patent of ZL200820114566.7 all refer to a kind of can the test platform of test fuel cell Performance data, this test board can monitor the relation between each operational factor and stack performance.Visible, domestic at present also do not have ripe simulation vehicle condition variable working condition test platform.
B, FCE system core instrument and equipment technology status at home and abroad is analyzed:
Abroad, Canada Hydrogenics company and FuelConSystems company, the U.S. some strong research and development institutions such as NI (NaionalInstruments) company, International Fuel Cell instrument company of the U.S. developed more practical test macro, the multinomial performance index of different fuel cells can be tested.Domestic having to when test fuel cell performance relies on external product and technology.Test macro spininess domestic at present to miniwatt fuel cell as test analysis object, rare dedicated development and the testing apparatus relating to automobile-used more than 50kW fuel cell system.
C, FCV power system critical equipment equipment technology status at home and abroad is analyzed:
Authorization Notice No. is the patent of invention " fuel cell hybrid system test Study system " of CN 1601792B, propose a kind of fuel cell hybrid system test Study system, but tested object is mainly for single motor driving fuel cell bus.Be also shown in the patent of invention that Authorization Notice No. is CN 101660972B, CN 101261189B.
Visible, based on alternating-current electric dynamometer system, driver's simulation, vehicle and the function such as Road quality simulation, driving cycle simulation is achieved by secondary development control system, dynamic load is carried out to test power system, thus build complete fuel cell car power drive system hardware-in-loop simulation testing table, there is no precedent at home.
D, FCV power system and critical component design of Simulation instrument and equipment technology status at home and abroad are analyzed:
The Modeling Research of current PEMFC system concentrates on system emulation and experimental analysis mostly.The research of mechanism model mainly to concentrate in Dan Chi and single pond on each unit.For PEM, the diffusion model based on proton solvent principle that the more representational Verbrugge of having (1990) proposes; For Catalytic Layer, Bultel (1998) has delivered the proton transfer model based on quality transfer principle; For diffusion layer, there is the quality forced convertion TRANSFER MODEL of Yi (1999); Also has the electrode model based on heat and mass principle of Bevers (1997).But how mechanism inner model and experience external model are combined, study suitable mathematical measure and spatial parameter distributed model is reasonably simplified to lumped parameter model, can reflect that the operation mechanism of HT-PEMFC heap inside is applicable to control design case again, such Modeling Research work not yet finds from the document published so far.
E, FCE, FCV power system experiment NVH environment technology status at home and abroad is analyzed:
The vibration noise of the current fuel-cell car sample car in the current whole world shows two features: noise is large, the sound poor quality of fuel cell car.
Because fuel-cell car general arrangement is different, most of fuel-cell car continues to use former internal combustion engine vehicle body.Although fuel-cell car eliminates this noise source of internal combustion engine, add the noise sources such as motor, fuel cell system, cooling system, and orthodox car covered by internal combustion engine noise under Noise in Air Conditioning System, fuel-cell car can embody to some extent.Compared with traditional combustion engine automobile, the total noise source of fuel cell car adds many, and presents the feature of promulgation formula noise source.Various sources is done down noise qualities inside and outside car is worsened jointly, and driver and occupant feel very poor.
Recent domestic has researched and developed the electric automobile concept sample car of the employing fuel cell power system driving much differed from one another in succession, but domestic except the research work of research group of Tongji University, for fuel-cell car vibration noise source---the vibration noise of fuel cell power system and the research of control thereof are almost still blank.
F, FC, FCE, FCV power system experimental temperature, humidity and pressure environment technology status at home and abroad are analyzed:
The experimental enviroment not yet having at present ripe equipment supplier can provide Fuel Cell Vehicle Powertrain and critical component thereof to be in the world suitable for, each large automaker is as general, benz, Toyota etc., the integrator of fuel cell and system is as Canadian Ballard company, NEWCELL of the UTC company of the U.S. and Germany etc. and some research institutions are as numerous and confused in the FCTec of U.S. Department of Defense and some equipment suppliers have developed the experimental enviroment of Fuel Cell Vehicle Powertrain and critical component cooperatively, and set up corresponding method of testing and standard according to the development Experience in each comfortable Fuel Cell Vehicle Powertrain field.And U.S. Department of Defense (DoD) and the FCTec (Fuel Cell Test and Evaluation Center) that the institution cooperation such as CTC company and AUS engineering developme center (The U.S.Army Engineer Research and Development Center) is set up establish the relevant testing apparatus of a complete set of fuel cell comprising experimental enviroment, and for comprising the testing research and assessment that the military provides fuel cell relevant with civilian.
Therefore, in sum, mainly there is following shortcoming for Fuel Cell Vehicle Powertrain at present:
1) there is no both at home and abroad by fuel cell and backup system hardware-in―the-loop test coupling, power drive system hardware-in―the-loop test coupling, Fuel Cell Vehicle Powertrain hardware in loop border test coupling three systems in the integral instrument equipment of one, device integration is not high;
2) there is no both at home and abroad and consider the integrated test system that temperature, humidity and pressure environment and NVH test the Fuel Cell Vehicle Powertrain dynamic property of variable parameter operation under matched environment;
