New energy automobile complete machine power test method

Abstract

The invention discloses a new energy automobile complete machine power test method, which comprises the following steps of 1, controlling a lifting frame on a bottom plate to lift through a lifting control system, and driving a new energy automobile to move to a specified position along the height direction; 2, enabling a dynamometer on the moving plate to directly face the hub, and keeping a reasonable distance between the dynamometer and the hub; 3, arranging a rotating head capable of adjusting the angle in a pitching mode and conducting axial fine adjustment on the posture frame, connecting a connecting end at one end of the rotating head detachably with the hub of the new energy automobile after lifting, and connecting a rotating shaft at the other end of the rotating head with a power device in the dynamometer, wherein the power device can drive the hub of the new energy automobile to rotate through the rotating shaft; and 4, after connection is completed, sending an instructiont to the road surface simulation system through the control total system, enabling the road surface simulation system to simulate the test state of the new energy automobile, and feeding back hub test data obtained by the dynamometer and the information acquisition system to the control total system.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle power testing, in particular to a new energy vehicle whole machine power testing method. Background technique [0002] A new energy vehicle is a vehicle that uses a single battery as the energy storage power source. It uses the battery as the energy storage power source, and supplies electric energy to the motor through the battery to drive the motor to run, thereby driving the car. New energy vehicles use electricity as power, avoiding the exhaust gas pollution caused by gasoline as power. It saves energy and greatly reduces the pollution to the environment. It has become impossible for the newly developed electric drive powertrain of new energy vehicles to simulate the vehicle test on the test bench to complete various DV verification and reliability tests. missing method. [0003] The towing test bench of the electric drive powertrain is mainly used to complete the relevant DV veri...

AI Technical Summary

Problems solved by technology

[0005] Its disadvantages are: 1. Two axial dynamometers are used to tow each other, and the powertrain under test is connected through a rigid half shaft. It is difficult to debug and align the bench, and installation is troublesome; 2. New energy vehicles are powered by batteries. If the new energy vehicle cannot be systematically tested, it may be extremely dangerous when used

For example, the problem of battery combustion or even explosion; 3. The traditional load test device for new energy vehicle chassis cannot satisfy the simulation of complex operating conditions and complex road conditions
