As shown in fig. 1 to fig. 2, this patent aims to provide a movable parallel operation test platform for hardware-in-loop simulation (HIL) test of an energy storage PCS controller, which has high applicability. At most two PCS controllers are supported to simultaneously carry out hardware-in-loop simulation test through integrating power management, a communication simulation system and a signal interface conversion panel. On the basis, parallel simulation test of a plurality of PCS controllers can be realized through the cascade combination of a plurality of test cars. This patent can not only satisfy the multiple hardware of energy storage PCS and need in ring simulation test, still makes the switching and the combination of test fixture become more nimble convenient, has improved efficiency of software testing.

As shown in fig. 1 below, a low-voltage power management module 4 integrated by hardware on a loop simulation test vehicle (simulation vehicle 1) can convert 230VAC into 24VDC and 15VDC, is responsible for supplying power to an EMS/BMS communication simulation system 5 on the simulation vehicle 1 and the main boards of tested PCS controllers (first PCS controller 6 and second PCS controller 7), and is controlled by a five-way independent dual-channel miniature circuit breaker 3. Because the physical interface of the I/O signal of the simulation machine generally adopts the DB37 specification, the I/O signal switching panel 2 on the simulation vehicle 1 can extract the interface signal of the DB37 specification and connect the interface signal to the tested PCS controller (the first PCS controller 6 and the second PCS controller 7) so as to realize the interactive mapping of the simulation signal. Meanwhile, according to actual test requirements, signal measurement and route switching can be rapidly realized through jumper operation on the I/O signal transfer panel 2. The EMS/BMS communication simulation system 5 is connected with the first PCS controller 6 and the second PCS controller 7 through communication lines, and can synchronously verify the correctness of the communication protocol between the PCS controller and the EMS/BMS system during HIL simulation test. When more than two PCS controllers are needed for parallel simulation test, a plurality of simulation test vehicles can be connected to the simulator according to actual needs to perform HIL simulation test experiments.

Fig. 2 is a schematic layout diagram of a hardware-in-the-loop simulation test vehicle, in which an I/O signal adapter panel 2 is mounted on the uppermost back-hanging plate 12 of the simulation vehicle 1. The upper layer and the middle layer of the simulation vehicle 1 are installation areas of all mainboards of the energy storage PCS controller to be tested, and the lowest layer is an installation area of the low-voltage power supply management module 4, the miniature circuit breaker 3 and the communication simulation system. In addition, two slots are designed on the back hanging plate 12, so that the lines can be laid and arranged conveniently, the reliability of the lines is improved, and the overall appearance of the tool is neater and more standard.

The test cases were as follows:

and installing the energy storage PCS controller to be tested to an upper installation area of the HIL test vehicle, and connecting a 24V power line, a communication line and all I/O signal lines. And connecting each I/O channel of the simulator with an interface conversion panel corresponding to the HIL test vehicle by using a DB37 signal wire. And starting the simulator, operating the energy storage PCS converter, the power grid and the battery model, supplying 220VAC power to the test vehicle, and closing the miniature circuit breaker beside the power management module to start various hardware-in-loop simulation test works. During the test process, corresponding signal measurement can be carried out through the I/O signal transfer panel, and the simulation signal route can be changed through a jumper wire according to actual needs.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
