Experimental test device and test method for multi-source power system

Abstract

The invention belongs to the technical field of new energy automobiles, and discloses an experimental test device and test method for a multi-source power system. The system is composed of an engine system, a generator system, a driving motor system, a power battery system and a dynamometer, an engine drives a generator to operate, and the generator outputs current for a driving motor to work or charging a power battery. The electric dynamometer can simulate a loading condition. All behaviors in the experiment are controlled by the whole vehicle model loaded in the PXI controller. Based on the test platform, experiments such as generator efficiency test, system efficiency test, working condition simulation test, whole vehicle model algorithm optimization and the like can be completed. According to the invention, through reasonable design and layout, a generator efficiency test, a motor and motor controller characteristic test, an engine performance test and a battery charging and discharging performance test can be realized at the same time. According to the invention, the PXI controller is used for loading the whole vehicle model, and the whole vehicle simulation test of the multi-source power system can be realized.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, and in particular relates to an experimental test device and a test method for a multi-source power system. Background technique [0002] With the continuous aggravation of the energy crisis and environmental pollution, new energy vehicles have received more and more attention and support, and their industry has also developed vigorously. At present, new energy vehicles can be mainly divided into four categories: pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles and fuel cell electric vehicles. Their main structures can be divided into engine system, generator system, drive motor system and battery system. Four major parts. At present, there are complete experimental platforms for each system, and detailed experimental research can be carried out. However, the establishment of experimental platforms for each system has problems such as large area, high investme...
