Description

Technical Field

[0002] Electrochemical battery energy storage technology, as a hot topic in the current energy storage field, has been widely used due to its excellent technical performance and life advantages. Among many energy storage technologies, it has become a mainstream trend, especially in the field of new energy, such as wind power and photovoltaic power generation, where it plays a vital role.

[0003] In terms of the consumption of new energy sources such as wind power and photovoltaic power generation, due to the intermittent and unstable nature of these new energy sources, the electricity they generate is often difficult to be directly integrated into the power grid. The electrochemical battery energy storage system can effectively solve this problem. It can store excess electricity and release it when needed, thereby balancing the load of the power grid and improving the utilization rate of new energy sources.

[0004] Existing electrochemical energy storage integrated devices do have some limitations in design, especially in terms of battery movement and heat dissipation. Due to the compact structure of the integrated device, the battery is often fixed inside, which is not convenient for quick disassembly and replacement, which limits the flexible application of the battery in different occasions. At the same time, the compact structure is also prone to poor heat dissipation, especially when running at high load, the battery temperature may rise rapidly, which not only affects the performance and life of the battery, but also may bring safety hazards.
