(referred to as "repower new energy"), a subsidiary of shenzhen repower industrial co., ltd. (referred to as "repower industrial"), provided core energy storage systems and overall solutions, has successfully achieved one-time grid-connection and stable operation after overcoming multiple challenges under the test of high-temperature and high-humidity environment in southwest china. this project sets a high-quality example for large-scale application of user-side energy storage in chongqing and southwest regions.
tackling complex environments: overcoming challenges with safe technology integrationchongqing's summer climate, characterized by high temperature, humidity, and frequent heavy rains, poses severe challenges to the installation and commissioning of large-scale outdoor energy storage equipment. the project team of repower new energy made scientific arrangements, optimized working hours, and formulated detailed plans to ensure precise installation of core equipment. facing limited space, its highly integrated containerized energy storage system demonstrated significant advantages. adopting industry-leading 1500v liquid-cooled battery technology, the system integrates advanced multi-level safety protection designs (including temperature, voltage, and current monitoring and linkage protection at the battery, module, and system levels). compared with traditional solutions, it achieves a 26% increase in energy density, a 20% reduction in system loss, and a 50% decrease in floor space, effectively lowering construction difficulty and costs while enhancing the system's safety level. the chongqing boe energy storage power station project has built a complete solution consisting of large-capacity liquid-cooled energy storage containers, high-efficiency intelligent boosting integrated machines (highly integrating converters pcs, transformers, and high-voltage switchgear), and advanced management systems. among them, the liquid cooling system not only ensures efficient heat dissipation and long-term reliability of batteries under high temperatures but also its precise temperature control capability significantly reduces the risk of battery thermal runaway; the intelligent boosting integrated machine improves the system's environmental adaptability and installation/commissioning efficiency, and its built-in electrical protection mechanism provides safety guarantees for the system's grid-connected operation.
as the intelligent management core of the entire project, the "intelligent microgrid management system" independently developed by shenzhen repower new technology has played a key role. this system integrates the energy management system (ems), battery management system (bms), fire protection management system, and energy dispatching system, providing full-dimensional monitoring, intelligent operation, real-time operation and maintenance, and big data analysis functions. it offers strong technical support for chongqing boe to achieve refined energy management and optimized dispatching. multiple values highlight win-win economic and social benefitsshenzhen repower new technology will continue to deepen energy storage technology innovation and engineering practice, providing safer, more reliable, intelligent, and economical solutions to assist customers in green and low-carbon transformation and energy cost optimization, contributing to the construction of a new power system and the promotion of the "dual carbon" goals. shenzhen repower new technology |
