Embodiment 1

[0022] Please refer to figure 1 , the embodiment of the present invention discloses a power drive system test platform for a fuel cell vehicle, the entire fuel cell vehicle is used as the object to be tested, and the test platform includes a simulation control platform 1, a vehicle controller 2 and an external load. It is used to simulate the vehicle operating environment of the measured object, and can provide the input and output signals required by the measured object, such as various sensor signals, switch signals and temperature signals; realize the signal acquisition of the measured object and the action execution of the actuator and other functions, such as accelerator pedal, brake pedal, vacuum pump system, etc.; provide state information collection during the operation of the measured object, such as the collection and monitoring of information such as voltage, current, torque, speed, temperature, etc., and carry out hardware acquisition and the measured object The co...

Embodiment 2

[0031] Please refer to figure 2 , the embodiment of the present invention discloses a fuel cell vehicle power drive system test platform, which is different from the fuel cell vehicle power drive system test platform disclosed in Embodiment 1 in that the energy storage battery system 5 different materials, the energy storage battery system 5 is a power battery system, and the power battery system includes a power battery 521 and a power battery management system 522 connected to each other. Since the power battery 521 can receive and store , high-voltage direct current provided by braking energy recovery device or external charging device, and provide high-voltage direct current for electric vehicles, using power battery 521 as new energy vehicles can provide continuous and stable power energy to drive vehicles, which is not only green and environmentally friendly, but also The safety is high, the service life is long, and it can meet the needs of daily driving. The power bat...

Embodiment 3

[0033] Please refer to image 3 , the embodiment of the present invention discloses a fuel cell vehicle power drive system test platform, which is different from the fuel cell vehicle power drive system test platform disclosed in Embodiment 1 and Embodiment 2 in that the storage The materials of the energy storage battery system 5 are different. The energy storage battery system 5 is a combination of a supercapacitor system and a power battery system. The supercapacitor system includes an interconnected supercapacitor 511 and a supercapacitor management system 512. The power battery system Including interconnected power battery 521 and power battery management system 522, so that the energy storage battery can not only have the advantages of fast charging of the supercapacitor 511, but also have the advantages of high safety and long service life of the power battery 521, fully ensuring When in use, the energy storage battery system 5 can store sufficient electric energy, the ...

Abstract

The invention relates to a test platform for a power driving system of a fuel cell vehicle. The test platform comprises a simulation control platform, a whole vehicle controller, and an external load.A real-time processor, a bus board, a fault injecting board, a signal conditioning module, a load simulating module, and an IO board are provided inside the simulation control platform. One end of the IO board is connected with the real-time processor, and the other end is connected with the load simulating module, the signal conditioning module, and the fault injecting board. The real-time processor is connected with all boards and modules inside the simulation control platform to collect signals and control related loads. All boards are connected with the whole vehicle controller through ahard wire and a CAN bus board, and is connected with the fuel cell system, the fuel cell DCDC system, the energy storage battery system, and the ECU in the motor system through the whole vehicle controller. According to the test platform for a power driving system of a fuel cell vehicle, the static and dynamic test of the high voltage component system of the fuel cell vehicle on the same test platform can be realized due to the fact that at least one of the above systems is an external load during testing.

Description

technical field [0001] The invention relates to an automobile test platform, in particular to a power drive system test platform for fuel cell vehicles. Background technique [0002] Fuel cell vehicles are currently in their infancy in China. Especially in 2018, the application of fuel cells in automobiles is being valued by various OEMs and related parts factories. Various fuel cell passenger vehicles, commercial vehicles, buses, logistics vehicles, etc. Introduced one after another; compared with the development of fuel cell vehicles, the test methods specifically for fuel cell vehicles are not perfect at present, and an effective test platform is urgently needed to systematically and comprehensively test and verify the entire high-voltage system. The invention aims at building a set of test and verification platform for realizing all high-voltage pipe fitting parts systems of the whole vehicle for the high-voltage system on the fuel cell vehicle. Contents of the inventi...
