AI Customer ServiceA liquid immersion cooling battery pack containing 60 batteries were established. At 2C discharge rate, 0.5 L/min flow rate was recommended. The battery pack can address localized high-rate discharge events (4.5C or 6.5C). Liquid immersion cooling BTMSs have great heat dissipation performance.
Also, not much research has been done on the combination of two liquid cooling systems or a hybrid liquid cooling system, and this is one of the growing topics in the field of battery thermal management systems, and the innovative channel designed in this study is related to this.
Conclusions The direct liquid cooling technique offers a considerable advantage by delivering a higher heat removal rate than other cooling methods for lithium-ion battery packs. Nevertheless, this cooling method has a significant issue during battery cells' high discharge current rates.
In addition, Flow cooling significantly reduces the battery pack's highest temperature and non-uniformity compared to immersion. According to the numerical results, using cooling tubes as an indirect cooling system integrated with the direct flow cooling method can remarkably improve the thermal efficiency of the battery pack.
