Automatic test system of electric automobile motor drive system performance

Abstract

The invention provides a system for automatically testing the performance of a motor driving system of an electric automobile, comprising a direct current power supply used for supplying energy to a motor to be tested by a motor transducer, a power analyzer used for testing the voltage and current of the direct current power supply and testing the voltage and current of the motor transducer, a torque master which is connected with the motor to be tested and a dynamometer machine and is used for testing the rotate speed and torque of the motor to be tested, a CAN module used for transmitting the signal detected by the torque master to a master computer, and the master computer used for collecting and processing the automatic testing information of the performance of the motor driving system. The master computer is in charge of unified and cooperative control, realizes the automatic testing on the performance of the motor driving system of the electric automobile, and automatically generates a testing report and analyzes the testing report. Pre-treatment of testing data is realized by separated modules, thus relieving the working strength of the master computer and ensuring the work flow to be smooth.

Description

technical field [0001] The invention relates to the field of electric vehicle motor drive systems, in particular to an automatic test system for the performance of the electric vehicle motor drive system. Background technique [0002] The motor drive system is the most critical part of the electric vehicle, and its performance directly determines the performance of the electric vehicle. Testing this is an important means to improve the performance of the motor drive system. At present, the test platform and method of motor drive system generally refer to the test platform and method of industrial motor, which is not suitable for the development of electric vehicle motor drive system. At the same time, the testing of the motor system requires a lot of manpower, which is not only inefficient, but also causes differences in the testing process and test results due to differences in operating proficiency. For the processing of test data, most of them are manually processed at p...

At present, the test platform and method of motor drive system generally refer to the test platform and method of industrial motor, which is not suitable for the development of electric vehicle motor drive system

At the same time, the testing of the motor system requires a lot of manpower, which is not only inefficient, but also causes differences in the testing process and test results due to differences in operating proficiency

For the processing of test data, most of them are manually processed at present, and the processing of experimenters with different skills will also lead to differences.
