Liquid cooling-based battery thermal management systems (BTMs) have emerged as the most promising cooling strategy owing to their superior heat transfer coefficient, including two modes: indirect-contact and direct-contact. Direct-contact liquid BTMs, also referred to as immersion cooling systems, have garnered significant attention.
High-power battery energy storage systems (BESS) are often equipped with liquid-cooling systems to remove the heat generated by the batteries during operation. This tutorial demonstrates how to define and solve a high-fidelity model of a liquid-cooled BESS pack which consists of 8 battery modules, each consisting of 56 cells (14S4p).
They found that the thermal management achieved through single-phase liquid cooling method can effectively and safely maintain desired temperatures within battery cells and modules. G. Satyanarayana et al. studied the immersion cooling performance of lithium-ion batteries using mineral oil and therminol oil.
A two-phase immersion liquid cooling system was established for large format Li-ion battery efficient heat dissipation. The maximum temperature and temperature variation in battery cell have been successfully limited at high discharge C-rates. The factors influencing the pool boiling in the cooling of Li-ion batteries were discussed.
However, the intermittent nature of these energy sources also poses a challenge to maintain the reliable operation of electricity grid . In this context, battery energy storage system (BESSs) provide a viable approach to balance energy supply and storage, especially in climatic conditions where renewable energies fall short .
The liquid cooling system comprise a condenser connected with external liquid loop (The coolant flow rate was kept at 8 L/min), a battery tank equid with a pressure meter (ZSE30AF, China), battery charge/discharge equipment (AODAN CD1810U5, China), a data acquisition instrument (FLUKE 2638A, USA), and an environmental chamber (GZP 360BE, China).
