一文读懂：同景二氧化碳直冷浸泡式液冷锂电池储能系统

Core Viewpoint - The article discusses the innovative cooling system for lithium battery energy storage developed by the company, which addresses the limitations of traditional ethylene glycol-based liquid cooling systems and enhances safety and efficiency in battery management [2][4]. Group 1: Technical Principles - The company’s carbon dioxide direct immersion cooling system for lithium batteries effectively resolves leakage issues associated with traditional immersion systems and maintains a stable cooling environment [4]. - The system utilizes phase change carbon dioxide cooling modules, achieving a water-free circulation and maintaining cost competitiveness with traditional cooling systems [4][6]. - The unique flow channel design allows for micro-circulation of the cooling liquid, ensuring uniform temperature distribution and enhancing the overall safety of the battery pack [4][8]. Group 2: Safety Features - The system features efficient thermal management, with temperature differences within the battery pack kept to a minimum, ensuring safe operation under high loads [8]. - It includes a mechanism to prevent thermal runaway, where the cooling liquid can directly enter the battery cell to lower temperatures during overheating incidents [9]. - The "suffocation" design actively reduces oxygen levels in the battery compartment, mitigating fire risks [10]. - The use of a carbon dioxide cooling system eliminates the risk of electrical short circuits caused by leaks from ethylene glycol solutions [11]. Group 3: Cost Advantages - The company’s energy storage system is cost-competitive with traditional cooling systems while providing higher temperature consistency and efficiency [13]. - The system's design reduces cooling energy consumption by up to 80% through centralized cooling and efficient thermal management [13][17]. - The cooling liquid has a long lifespan of up to 15 years, with minimal annual loss, contributing to lower operational costs [16]. Group 4: Development Platform - The company has a 20MWh user-side energy storage demand that serves as a testing platform for optimizing system performance and safety [20]. - The first standard product of the company is set to be operational by the end of 2025, which will help refine product details and align with market needs [20]. - The company has secured approval for a demonstration project in collaboration with major state-owned enterprises, enhancing its market position and brand influence [20].
