Novel test method of control response time of motor of new energy automobile

Abstract

The invention discloses a novel test method of the control response time of a motor of a new energy automobile. According to the invention, a central controller is provided and an operation control system is arranged in the central processor; the operation control system is used for carrying out operation and performing remote control and parameter setting on devices in a test system in a human-machine interaction manner; a motor direct current power supply measurement device and a motor direct current load measurement device are arranged in the operation control system; and the motor direct current power supply measurement device calculates the control response time of a to-be-tested motor through an oscilloscope. In this way, response time of the motor can be objectively and precisely measured; effects imposed by human factors are overcome; the test results are quite reasonable and capable of precisely reflecting operation performance of the motor in an electric automobile, thereby facilitating production of the automobile; test technical means and test technical support are provided; and the method is novel in design ad is a good creative scheme.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a method for testing response time of motor control of new energy vehicles. Background technique [0002] There are uncertain factors in the communication between the control command issued by the electric vehicle and the output response of the charger. New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with For vehicles with new technology and new structure, the response time of charger charging control should include the time from when the electric vehicle sends out the control command to the actual output required value of the charger. This time is a direct response to the interaction between the charger and the electric vehicle. Howe...

New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with For vehicles with new technology and new structure, the response time of charger charging control should include the time from when the electric vehicle sends out the control command to the actual output required value of the charger. This time is a direct response to the interaction between the charger and the electric vehicle. However, there are deficiencies in it, and it is not convenient to measure the response time of the motor controller.
