Abstract

The invention relates to an off-line detection device for a driving motor of an electric vehicle. The off-line detection device comprises the driving motor to be detected, a load motor, a controller of the motor to be detected, a controller of the load motor, a power supply and an upper computer, wherein an output shaft of the load motor is connected with an output shaft of the driving motor to be detected sequentially through a torque sensor and an inertia wheel group, the upper computer is connected with the torque sensor and respectively connected with the driving motor to be detected and the load motor through the controller of the motor to be detected and the controller of the load motor, and the power supply is respectively connected with the driving motor to be detected, the load motor and the torque sensor. According to the off-line detection device for the driving motor of the electric vehicle adopting the structure, the motion of the motor can be automatically controlled by setting control parameters of the upper computer, and the testing of various load working conditions of the motor to be detected can be realized; simultaneously, the load motor can be used as a power generator, thereby circulating electric energy and saving the energy; and the motor which is the same with the motor to be detected is taken as a load, thereby further reducing the detection cost.

Description

technical field [0001] The invention relates to the technical field of electric vehicle production and manufacturing, in particular to the technical field of electric vehicle motor detection, and specifically refers to an electric vehicle drive motor off-line detection device. Background technique [0002] The needs of the national energy strategy put forward urgent requirements for the development of new energy vehicles, especially electric vehicles (EV). Compared with the traditional automobile industry, the development of electric vehicles has dual benefits of energy saving and environmental protection, especially in terms of total energy conversion efficiency and total emissions, and electric vehicles have obvious advantages, which is the development direction of the future automobile industry. [0003] In the past five years, my country has made great progress in electric vehicle technology, electric vehicle drive motor technology has entered a period of rapid developme...
