Abstract

The invention discloses an automatic working condition test system and method for an electric drive system of a new energy automobile. The system comprises a battery simulator, a motor controller, a motor, a dynamometer motor, a dynamometer control unit, a waterway circulating cooling system and a power analyzer, and the motor controller is flexibly connected with the battery simulator; the motoris flexibly connected with the motor controller, the dynamometer motor is mechanically connected with the motor through a transmission shaft and a flange plate, the dynamometer control unit is flexibly connected with the dynamometer motor, the cooling system is flexibly connected with the motor and the motor controller, and the power analyzer is flexibly connected with the motor controller. The system is clear in circuit, convenient to test and analyze faults, low in maintenance cost and high in accuracy of automatic working condition test results, and meets the requirements of different vehicle types; and moreover, the simulation road environment test work under the automatic working condition is verified and realized, and is closer to the real state.

Description

technical field [0001] The invention relates to an automatic working condition testing system and method for an electric drive system of a new energy vehicle, and belongs to the technical field of testing the electric drive system of a new energy vehicle. Background technique [0002] The development of the automobile industry promotes the progress of human society, makes great contributions to the development of modern society and economic growth, and brings convenience and comfort to people's lives. However, with the increasing exploitation of crude oil, the shortage of natural resources is becoming more and more serious; the large amount of automobile exhaust emissions, It also has an inescapable responsibility for global warming and the deterioration of the natural ecological environment. Therefore, in response to the concept of green environmental protection, new energy electric vehicles have gradually entered the public's sight and have received more and more attention...
