The invention discloses a fuel cell hydrogen energy automobile multi-energy power system test bench. The fuel cell hydrogen energy automobile multi-energy power system test bench is characterized by comprising a frequency conversion inversion system, a first electric dynamometer group, a second electric dynamometer group, a third electric dynamometer group, a fourth electric dynamometer group, a first motor group, a second motor group, a master control unit, a data acquisition unit, a data analysis unit, a multi-energy power system and a CAN2 bus. According to the test bench, a power system joint test can be carried out on various new energy sources such as a hydrogen fuel cell, a power cell and a super capacitor; a standard working condition or a self-defined working condition can be simulated to verify an energy management strategy of the multi-energy power system of a new energy vehicle; and simulation data can be compared with emulation data, online modification and parameter calibration of an energy management control strategy are supported, and effective unification of the simulation data and bench data is achieved.
Description
technical field [0001] The invention relates to the field of automobile test benches, in particular to a fuel cell hydrogen vehicle multi-energy power system test bench. Background technique [0002] At present, new energy vehicles have become the technical route of national key development. With the application of new energy in vehicles, there are more and more types, such as electric energy, hydrogen energy, solar energy, etc., so there are various energy combinations in the power system of new energy vehicles. , the energy management strategy between multiple energy sources is particularly important. At present, traditional test benches have limited support for new energy sources, and cannot effectively verify the energy management strategies of multi-energy power systems. Therefore, it is necessary to invent a new energy vehicle multi-energy power system test bench and a verification method for management strategies. Contents of the invention [0003] In order to sol...
