Benefits of technology

[0017]The present invention describes a combiner communication box for multi-cluster parallel operation in a high-voltage energy storage system. It constructs a combiner assembly based on battery combiner terminals and a circuit breaker, and a communication assembly based on a main control board, a communication board, battery communication interface terminals, and inverter communication interface terminals. This achieves combiner communication connection between the multi-cluster parallel batteries and the inverter. The main control board connects to the communication interface terminals of the multi-cluster parallel batteries through battery communication through-holes, collecting and summarizing the operating parameters of each cluster of batteries in real time. The communication board transmits the summarized data to the inverter through inverter communication through-holes, while simultaneously receiving power data from the inverter, realizing a closed loop of data acquisition, summarization, transmission, and command feedback. The combiner assembly and communication assembly of this invention are physically isomorphic and logically linked, achieving synchronous feedback between the multi-cluster parallel batteries and the inverter without the need for additional coordination modules. This reduces the number of connecting cables between devices, lowers the risk of failure due to cable connections, and thus improves the overall stability of the high-voltage energy storage system. Furthermore, it eliminates the need for separate combiner cabinets and communication gateways, significantly reducing the number of independent components in the system, saving installation space, and improving operation and maintenance efficiency.
