先进技术应用
让储能电站运营更高效、安全
高能量密度、模块化设计：项目采用的5MWh储能集装箱，使用314Ah大容量磷酸铁锂电芯，让20尺集装箱能实现5MWh的储能容量，相比主流的280Ah电芯的储能系统，能量密度有显著提升。
同时，产品设计模块化程度高，由多个电池模块组成电池簇，电池簇直流侧并联后接入PCS直流侧。整舱结构紧凑，便于运输、安装和维护。
先进的热管理系统：采用液冷热管理方式，通过乙二醇水溶液流经电池pack底部冷板对电芯进行换热，还增加电池pack温度传感器数量和精度、提升液冷机组制冷效率，确保pack内和柜体的温差管控。
可靠的安全防护体系：配备全氟己酮消防保护系统等，设置pack、簇、舱三级自动报警灭火系统。集装箱内安装温湿度、烟雾、视频监测和门禁状态监测设备。
智能的电池管理系统：具备先进的智能化电池管理产品，可实时监测电池的电压、电流、温度等参数，对电池进行充放电控制和均衡管理，确保电池组的性能和安全。
大幅提高电站经济效益
助力电网调峰调频
节省成本：以常规项目容量100MWh计算初始投资成本，5MWh液冷储能系统比主流3.72MWh产品占地面积节省43%，成本节省26%。
循环寿命长、能效水平高：采用314Ah大容量磷酸铁锂电芯，循环寿命超8000 次，使用寿命可达25年。
产品采用的电芯能效水平高于95%，同时实现直流侧95%@0.5P的高能效水平，能为客户节能降耗，提升收益。
适用范围广：整体防护等级高，IP54级别 ，可在高温暴雨、风沙暴晒等恶劣环境中稳定运行。
提升系统稳定性：相比常规搭载280Ah电芯的3.35MW/6.7MWh方案，5MW/10MWh方案可提高安全稳定运行能力，减少故障率。
响应快速灵活：可快速响应电网的需求变化，实现电力的快速存储和释放，在电网频率调节、电压支撑等方面具有良好的性能，能有效提升电网的稳定性和可靠性。
连云港东海储能电站项目的建成，在保障电力供应可靠性的同时，将为当地经济社会发展提供坚实的电力支撑。并通过储能电站的示范引领作用，吸引更多新能源相关企业集聚，形成产业集群，持续增强连云港绿色产业发展的后劲。
未来，海克森能源将继续深化储能技术创新与应用实践，与各方携手共进，推动更多储能项目的落地实施，为构建更加清洁、高效的能源体系贡献力量。
Recently, the Lianyungang Donghai 50MW/100MWh energy storage power station project, supported by Hexoness Energy"s technical assistance, was successfully connected to the grid in Donghai County, injecting strong impetus into the new energy development of Lianyungang.
The Lianyungang Donghai 50MW/100MWh energy storage power station project is located in Donghai County, Lianyungang City, Jiangsu Province, covering an area of about 43 mu, with a total installed capacity of 100MWh. Hexoness, as the energy storage equipment provider, has offered a complete set of energy storage product solutions for this project.
The container products used in the project employ 314Ah large-capacity lithium iron phosphate cells, enabling a 20-foot container to achieve a 5MWh energy storage capacity. Compared with the mainstream 280Ah cell energy storage system, the energy density has been significantly improved. The products also have multiple advantages such as liquid cooling thermal management, a comprehensive safety protection system, and an intelligent battery management system, making the operation of the energy storage power station more efficient and safe.
Calculating the initial investment cost based on a conventional project capacity of 100MWh, the 5MWh liquid-cooled energy storage system saves 43% of the land area and 26% of the cost compared with the mainstream 3.72MWh product. At the same time, the long product cycle life and high energy efficiency level truly enable the energy storage power station to play the role of a stabilizer in the power grid system.
The completion of the Lianyungang Donghai energy storage power station project will not only ensure the reliability of power supply but also provide solid power support for the local economic and social development. Through the demonstration and leading role of the energy storage power station, it will attract more new energy-related enterprises to gather and form an industrial cluster, continuously enhancing the momentum of Lianyungang"s green industrial development.
In the future, Hexoness Energy will continue to deepen the innovation and application practice of energy storage technology, join hands with all parties to promote the implementation of more energy storage projects, and contribute to the construction of a cleaner and more efficient energy system.
