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

Embodiment Construction

[0046] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0047] This example: see Figure 1 to Figure 6 , a new energy vehicle power test method, including the following steps:

[0048] Step 1: Make a power test device for the whole new energy vehicle. The power test device includes a lifting frame that is arranged in the workbench 1 and can drive the new energy vehicle 5 to move along the height. On the workbench 1, the four hubs of the new energy vehicle 5 are connected At the corresponding position, there are four attitude frames 7 that can move radially and / or axially. The attitude frame 7 is provided with a rotating head that can adjust the angle of pitching and tilting and fine-tune the axial direction. The connecting end 19 of the wheel hub of the energy vehicle 5 is detachably connected, and the other end is provided with a rotating shaft connected with the power device in the dynamometer 6, and the po...

Abstract

The invention discloses a power testing method for a complete machine of a new energy vehicle, comprising the following steps: step 1: controlling the lifting and lowering of a lifting frame on a base plate through a lifting control system, and driving the new energy vehicle to move to a designated position along the height direction; step 2: moving a board The dynamometer on the top is facing the wheel hub, and a reasonable distance is maintained between the dynamometer and the wheel hub; Step 3: The attitude frame is provided with a rotating head that can adjust the angle of pitch and axial fine-tuning, and pass the connecting end of one end of the rotating head. It is detachably connected with the wheel hub of the new energy vehicle after lifting, and the rotating shaft at the other end of the rotating head is connected with the power device in the dynamometer. The power device can drive the wheel hub of the new energy vehicle to rotate through the rotating shaft; Step 4: After the connection is completed, The control system sends instructions to the road simulation system, the road simulation system simulates the test state of the new energy vehicle, and feeds back the wheel hub test data obtained by the dynamometer and the information acquisition system to the control 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 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 to provide electrical 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 using gasoline as power. It saves energy and greatly reduces the pollution to the environment. It has become impossible to complete various DV verifications and reliability tests for the newly developed electric drive power assembly of new energy vehicles in the test bench to simulate the whole vehicle test. missing method. [0003] The electric drive power assembly pair drag test bench is mainly used to complete the relevant DV ve...
