Embodiment Construction

[0022] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0023] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical," "horizontal," "left," "right," "u...

Abstract

The invention discloses a system for testing a motor. The system comprises an upper computer, a main control system, a vehicle control unit, a motor controller, a power battery system, a dynamometer,a power analyzer and a torque measurement instrument. The main control system, the upper computer, the vehicle control unit, the motor controller and the power battery system are connected through a CAN bus, the motor controller is connected with the driving motor to be tested, the vehicle control unit is connected with an accelerator pedal, a braking pedal and gears, and used for sending a control instruction to the motor controller, the motor controller is used for controlling the rotating direction, rotating speed and torque of the driving motor after receiving the control instruction, thevoltage, current, temperature and other parameters of the driving motor are fed back to the upper computer in real time through the power analyzer, and the torque measurement instrument is used for measuring and feeding back the actual output torque and rotating speed of the driving motor to the main control system for calculation. With the system, the problems that a testing environment is difficult to deploy, and testing data is largely different from actual vehicle data can be solved.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a motor testing system. Background technique [0002] With the rapid development of the automobile industry and the continuous improvement of people's living conditions, automobiles have become one of the indispensable means of transportation for people. The number of cars is increasing year by year, and more and more people own private cars. With the depletion of oil resources and the enhancement of people's awareness of environmental protection, traditional fuel vehicles have gradually changed to new energy vehicles. [0003] New energy vehicles include pure electric, hybrid and fuel cell vehicles, etc. For new energy vehicles that use motors and batteries as electric drive and energy recovery devices, their electric drive systems generally include drive motors and motor controllers, among which drive motors It is the active power of new energy vehicles, so it is ne...
