[0047] Further, combined with Figure 1 A storage cabinet 11 for placing items is provided on the front side of the platform 1, which can be used to place some teaching and training tools, such as an AC charging gun for charging.

[0048] In order to facilitate the movement of the platform 1, walking wheels are installed at the four corners of the bottom end of the platform 1.

[0049] During training, first turn on the safety maintenance switch 42 to connect two battery modules of the power battery pack 41 connected to the safety maintenance switch 42, then turn on the emergency stop switch 31, turn on the ignition switch 32 to connect the circuit, and the total voltage, total current and single cell voltage of the power battery pack 41 can be displayed on the information display screen 25.

[0050] Manually pressing the accelerator pedal 63 simulates the acceleration of the electric vehicle, and under the action of the motor controller 62, the drive motor of the drive motor assembly 61 rotates. Depending on the amplitude of pressing the accelerator pedal 63, the drive motor obtains different speeds.

[0051] When shutting down the training simulation device, the ignition switch 32 is first turned off, and then the emergency stop switch 31 is opened.
