[0002] In the process of developing new energy storage PCS products, hardware-in-the-loop simulation testing (HIL) can effectively verify the correctness and feasibility of the control scheme. The necessary prerequisite for hardware-in-the-loop simulation testing is to build simulation test fixtures, connect the simulator and the controller under test, and realize the two-way transmission and reception of digital and analog signals, which requires the use of energy storage PCS test equipment.

[0003] For example, the patent website discloses a hardware-in-the-loop simulation test vehicle for energy storage PCS (publication number: CN218455843U). This device requires the energy storage PCS controller to be installed on the device for testing, but there is no structure to fix the PCS controller, so the vibration of the device may cause the connection between the PCS controller and the device to loosen. At the same time, when the device moves, the PCS controller may shake on the device, causing the controller to be bumped. Therefore, those skilled in the art have proposed an energy storage PCS test device. Summary of the invention
