The invention discloses an electric driving force assembly testing system. The electric driving force assembly testing system includes: a tested electric drive group, and the tested electric drive group includes: a plurality of tested electric drives, each tested electric drive There are two power output ends; the auxiliary test electric drive group, the auxiliary test electric drive group includes: multiple auxiliary test electric drives, each auxiliary test electric drive is equipped with two power input ends; The number is the same as the number of multiple auxiliary test electric drives, and the two power output terminals of each tested electric drive are respectively connected to one power input end of the two auxiliary test electric drives. Thus, by connecting the tested electric drive group with the auxiliary test electric drive group, the tested electric drive can work at a specific speed and torque, so as to realize the determination of the fatigue reliability of the electric drive powertrain, which is comparable to the existing technology. Compared with that, the loss of the electric drive powertrain test system is smaller, and the structure of the electric drive powertrain test system is simpler, so that the cost of the fatigue reliability test of the electric drive powertrain can be reduced.
Description
technical field [0001] The invention relates to the technical field of testing, in particular to an electric drive power assembly testing system. Background technique [0002] In the related art, the electric driving power assembly is arranged on the electric vehicle, and the fatigue reliability test of the electric driving power assembly needs to be carried out during the design process of the electric driving power assembly.
