In this embodiment, the power supply simulation device simulates the device actually supplying power to the voltage converter, and may be, for example, a simulated high-voltage and a programmed power supply. The load simulator is a load device that simulates consumption of the output voltage of the voltage conversion controller, and may be, for example, a simulated electric device in a vehicle, such as an air conditioner. The expected operation value is an energy value required for the load simulator to operate normally, and may be, for example, an expected voltage value, an expected signal command, expected failure information, or the like. The expected signal instruction may be a wake-up instruction or the like, and the expected fault information may be an expected fault code or the like.
For example, the real-time simulation system may simulate the high-voltage power supply through a hardware-in-loop simulation platform, and then control the high-voltage power supply to provide the input power to the voltage conversion controller. Specifically, the real-time simulation system simulates the high-voltage power supply through the hardware-in-the-loop simulation platform, and sends a control instruction for supplying power to the voltage conversion controller to the simulated high-voltage, so that the simulated high-voltage power supply transmits electric energy to the voltage conversion controller.
