[0002] The battery energy storage system is an advanced power technology that not only stores electrical energy, but also releases energy when needed. The battery cell, as the core of the energy storage system, is a key component responsible for storing electrical energy.

DETAILED DESCRIPTION

[0029] Herein, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.

[0031] To facilitate the understanding of the pipeline structure and energy storage system provided by the embodiments of the present application, the application scenario thereof is first described. The pipeline structure and energy storage system provided by the embodiments of the present application are used to measure the inlet and outlet flow of the liquid cooling plate by replacing the three-stage pipeline. The measurement of flow and pressure drop is not only more efficient and convenient, but also less likely to damage the pipeline and instruments. The battery energy storage system is an advanced power technology that can not only store electrical energy, but also release energy when needed. The battery cell, as the core of the energy storage system, is a key component responsible for storing electrical energy. The temperature difference of the battery cell in the liquid-cooled energy storage system has a greater impact on the system life, SOH, and system balancing. The flow distribution of the liquid cooling plate and the flow resistance of the liquid cooling plate are important factors affecting the temperature difference of the battery of the energy storage system. Whether the flow distribution and the pressure drop of the liquid cooling plate are reasonable needs to be detected through experiments. At present, there are two methods of simulation experiment and actual measurement to understand the flow distribution and pressure drop of the liquid cooling system for each battery pack. However, simulation often does not consider the problem comprehensively, and the simulated working condition deviates from the actual situation, and sometimes the calculation result cannot reflect the true situation. The actual measurement method is more reliable than simulation and can more comprehensively and accurately reflect the problem. However, there are many three-stage pipelines connecting the battery packs in the energy storage system. To measure the inlet and outlet water flow and pressure drop of each battery pack, the instruments need to be disassembled and installed, which is complex, and frequent disassembly and installation may damage the pipeline or instruments, affecting the performance of the product and the instruments. Therefore, the embodiments of the present application provide a pipeline structure and energy storage system to measure the inlet and outlet flow of the liquid cooling plate by replacing the three-stage pipeline. The measurement of flow and pressure drop is not only more efficient and convenient, but also less likely to damage the pipeline and instruments. The embodiments of the present application will be described in detail below with reference to the specific drawings.
