Figure 1 and Figure 2 As shown, the extended-range system test bench includes a test bench 1, a partition plate 2, a display screen 4 and a control box 6. The test bench 1 is divided into a front side and a rear side by the partition plate 2. The front side is used to fix and install multiple test motors 5, and the rear side is correspondingly provided with multiple fixing seats 9 for installing couplings; the test motor 5 is installed with a current and voltage tester, and the coupling is installed with a torque and speed tester; the partition plate 2 is provided with a display screen 4 and a control box 6, and the control box 6 is used to start the test motor 5, as well as collect data from the current and voltage testers and the torque and speed testers, and send the data to the display screen 4 for display.

[0018] The test bench 1 includes a table top and legs. The four sides of the table top are supported by the legs. Considering that the rotation of the test motor 5 is likely to cause the vibration of the test bench 1, the bottom of the legs is fixed to the ground by bolts. The table top and the legs are made of stainless steel. Furthermore, the upper surface of the table top is covered with a rubber layer to prevent leakage and play a role in buffering and shock absorption.

[0019] The partition plate 2 is also made of stainless steel and covered with a rubber surface. The partition plate 2 is located in the middle of the test bench 1, and the test bench 1 is evenly divided into a front side and a rear side by the partition plate 2, so that the front side and the rear side have the same shape and size. A plurality of through holes 8 are provided on the partition plate 2 for connecting the test motor 5 with the coupling.

[0020] A control box 6 and a display screen mounting seat 7 are provided at the upper end of the partition plate 2. A control panel 3 is provided at the front end of the control box 6. The control panel 3 is located at the front side of the test bench 1 and is provided with a plurality of start buttons, which are used to start and shut down the test motor 5. A plurality of display screen mounting seats 7 are provided at the lower end of the control box 6 for mounting a display screen 4, which is used to display the voltage, current, speed and torque data of the test motor 5.

[0021] Furthermore, a temperature sensor is installed on the surface of the test motor 5. Similarly, the data of the temperature sensor is sent to the control box 6 and displayed on the display screen 4. The range-extending system test bench in this embodiment is provided with five test positions, each of which is provided with a test motor coupling flange, a display screen and a fixing seat. A maximum of five test motors 5 are installed, and correspondingly, five display screens 4 are provided and five fixing seats 9 are provided.

[0022] The test motor 5 is fixed above the connection flange on the front side of the test bench 1, and includes a motor and a controller. The motor is connected to a three-phase AC power line, and the controller is connected to a DC power line. The three-phase AC power line and the DC power line are both controlled by a control box 6, and are specifically turned on and off by buttons on a control panel 3. The three-phase AC power line and the DC power line are both installed with a current and voltage tester for measuring the voltage data and current data of the test motor 5. The current and voltage tester is measured by a voltage sensor and a current sensor.

[0023] The control box 6 adopts a PLC control box, model Siemens S7-300, which has powerful processing capabilities and rich functions. This series adopts modular design, including CPU module, digital input / output module, analog input / output module, etc.

[0024] The fixing seat 9 is used to install the coupling and the test transmission shaft connected thereto. The other end of the test transmission shaft is provided with a torque and speed tester. The data of the torque and speed tester are sent to the control box 6 and displayed on the display screen 4. During the test, the motor 5 to be tested is flush with the height of the center line of the coupling, the motor 5 to be tested is inserted into the inner cavity of the coupling, the coupling is tightened, and the load torque of the motor 5 to be tested is changed by the transmission of the test transmission shaft.

[0025] When in use, the utility model tests the motor and the controller by simulating actual driving conditions. At the same time, the system performance is evaluated by real-time monitoring of parameters such as current, voltage, speed, torque, etc. The temperature is evaluated by real-time monitoring of the temperature changes of the motor and the controller to evaluate the heat dissipation performance of the system.

[0026] The utility model has the following advantages: (1) it can realize routine testing of the motor and controller, current, voltage, speed, torque and temperature of the range-extended vehicle; and (2) as the electric vehicle market continues to expand, the application prospect of the test bench is broad.
