Computational fluid dynamic analyses were carried out to investigate the performance of a liquid cooling system for a battery pack. The numerical simulations showed promising results and the design of the battery pack thermal management system was sufficient to ensure that the cells operated within their temperature limits.
It can be investigated that the battery pack with active water cooling system performance is the best due to the lowest temperature rise and temperature difference at low cycling rate.
Therefore, it can be concluded the water cooling system is still the best choice to improve the battery pack thermal performance at low cycling rate, and it may be a better choice to design a compound system with PCM and water cooling, dealing with the situation of using battery pack in wide range at different rates.
At present, the mainstream battery thermal management systems is mainly divided into three categories, namely air cooling , , , , , liquid cooling , , , , and phase change material cooling , .
A numerical study of coupled electrochemical-thermal behavior of a lithium ion battery pack with bipolar design. The temperature window of the battery pack at various discharge rates is identified by the study of two limiting cases. A thermal management of forced liquid cooling is employed and several design parameters are studied and analyzed.
Liquid cooling with water, oil or refrigerant as the heat-transfer medium has a high volume efficiency, low location sensitivity [21] and is effective for heat removal from large-scale battery packs [22] (see the detailed review of various thermal management methods by Rao and Wang [23] for more details).
