According to the structure, hardware devices such as an energy storage battery and PCS in the energy storage system are important, but a control system such as BMS is also a key for guaranteeing safe operation of the system. Therefore, the control system of the software class is tested in the early stage of the project and before the production and installation of the hardware equipment, and the problem of software program self is found and modified in time, so that the phenomena of equipment and related personnel safety threat caused by hardware equipment fault alarm delay, even alarm omission and the like due to software program errors in the whole test process of the system can be avoided, the test time is shortened, the test efficiency is improved, and the phenomena of equipment safety threat caused by software program errors in the whole test process of the system can be avoided.
Therefore, the energy storage system testing device provided by the embodiment of the application can be applied to testing the control system of the software class in the current period of the energy storage system item. Fig. 1 is a block diagram of a structure of the energy storage system testing device. Referring to fig. 1, the energy storage system testing apparatus 10 includes:
The battery simulation system 11 is configured to simulate an energy storage battery of an energy storage system to generate battery test data, and transmit the battery test data to a control system 230 to be tested in the energy storage system, so as to test a response function of the control system to the battery test data;
