Abstract
The invention provides a high-dynamic electricity-driven drive system overall performance test system. The system comprises a tested drive system, a dynamometer system, a main control unit, a controllable bidirectional power supply and a cooling system. The dynamometer system is a small-inertia electric dynamometer system, the tested drive system is directly connected with the small-inertia electric dynamometer system, which removes large-inertia structures such as a variable speed gear and the like, and greatly reduces the self inertia of the system. The electric dynamometer system can actively realize zero inertia simulation, which causes the test system to be tested in high dynamic state. Continuous regulation of inertia can be achieved, which overcomes the problem of discontinuous regulation of mechanical inertia. The tested drive system and the dynamometer system are in a two-path arrangement in response to the performance test of the drive system of a multi-driven electric vehicle.

Description of drawings
Fig. 1 is the schematic diagram of full performance test system of high dynamic electric drive system of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further details.
Full performance test system of high dynamic electric drive system of the present invention, comprise the controllable bidirectional power supply, tested drive system, it comprises tested system control unit and tested system drive motor, dynamometer system, it comprises dynamometer machine body and Dynamometer Control unit, cooling system and main control unit.Described dynamometer system adopts little inertia electric dynamometer system, tested drive system directly links to each other with described little inertia electric dynamometer system, save except big inertia structures such as speed change gears, reduced self inertia of system greatly, the electric dynamometer system can eliminate the moment of inertia of self by electric inertia simulation, initiatively realize zero inertia simulation, make that test macro can high dynamic test.Described tested drive system and described dynamometer system adopt two-way to arrange, can be very the performance of good simulating vehicle bilateral wheel drive operating mode, for single motor-driven, Dual-motors Driving or how motor-driven system, all can extraordinary satisfied test needs.
Full performance test system of high dynamic electric drive system of the present invention is finished the coordinating and unifying by main control unit by the CAN bus, comprises work such as parameter setting, test event selection, test data processing.The CAN bus has been reserved external standard interface simultaneously, can conveniently insert equipment or system with standard CAN agreement, has strengthened the dilatation performance of system.
When tested drive system is done when initiatively moving, the controllable bidirectional power supply provides electric energy to it, after tested system control unit conversion, offer tested system motor, be converted to mechanical energy, thereby drive the dynamometer system action, electric dynamometer will produce electric energy this moment, after the conversion of Dynamometer Control unit, feed back to the power input of controllable bidirectional power supply, thereby the feedback that realizes energy reclaims.When tested drive system is done passive movement, be that it drives running by dynamometer system, then the dynamometer system control module is provided electric energy and is produced mechanical motion by the controllable bidirectional power supply, tested system motor generating input end controllable bidirectional power supply after tested system control unit conversion realizes that equally the feedback of electric energy reclaims.The electric energy of test macro deficiency obtains from electrical network.
Cooling system links to each other with test macro, and its flow and circulating temperature are coordinated control by main control unit, thereby realizes the thermal cycle test to tested system.
Dynamometer system can be realized the zero-based continuous online adjusting of moment of inertia need not to add any physics inertia via main control unit.The realization of zero inertia has guaranteed system for the high dynamic test request of tested system, and the continuous adjusting of inertia then realizes the performance test for different drive system coupling vehicles, measuring accuracy height, testing efficiency height.
