Low-temperature life-extension device for energy storage system adaptable to various natural cold source conditions

This invention relates to a low-temperature life-extension device for energy storage system adaptable to various natural cold source conditions, which is used to improve the service life of land-based or offshore energy storage systems under random conditions. The device connects to low-temperature water bodies from external natural cold sources through pipelines, utilizing the external natural cold source to directly cool the system. This reduces heat dissipation consumption, extends the equipment's service life, and saves substantial costs. The invention extends the service life of the battery modules by designing a low-temperature environment, reduces battery capacity fluctuations, and decreases long-term maintenance costs. It offers higher economic efficiency and reliability, especially suitable for new energy storage scenarios such as wind power and solar energy. In contrast, although subsea energy storage systems can also utilize external natural cold sources, their special sealing requirements, environmental conditions, and technical difficulties lead to extremely high costs.
