Guoxuan High-Tech has applied for a patent for a container-based energy storage system and battery management system, aiming to enhance the usable capacity of energy storage containers. According to information from the National Intellectual Property Administration, the patent titled “A Container-Based Energy Storage System and Battery Management System” was filed by Hefei Guoxuan High-Tech Power Energy Co., Ltd., with the publication number CN 119650907 A, and was submitted on February 2025.
The patent abstract reveals that the invention pertains to a container-based energy storage system and battery management system. The battery management system includes multiple three-level Battery Management Systems (BMS), where each three-level BMS is communicatively connected to multiple two-level BMS, and each two-level BMS connects to several one-level BMS. Each one-level BMS is linked to the corresponding battery module in the energy storage system. One of the three-level BMS units is designated as the master three-level BMS, while the remaining units are configured as slave three-level BMS. All slave BMS units communicate with the master three-level BMS.
This design adopts a master-slave configuration for the three-level BMS to expand the number of battery clusters and reduce internal cell circulation, ultimately increasing the usable capacity of the energy storage container.
According to Tianyancha, Hefei Guoxuan High-Tech Power Energy Co., Ltd. was established in 2006 and is located in Hefei City. The company primarily engages in the manufacturing of electrical machinery and equipment, with a registered capital of 1 billion RMB and a paid-in capital of 202.21 million RMB.
