Herein, thermal management of lithium-ion battery has been performed via a liquid cooling theoretical model integrated with thermoelectric model of battery packs and single-phase heat transfer.
Over the last decade, there have been numerous attempts to develop effective thermal management systems for commercial lithium-ion batteries. However, only a few analyze and compare thermal management techniques based on a control-oriented viewpoint for a battery pack.
The result can be thermal runaway and combustion in some cases. Therefore, it is essential to have an efficient battery thermal management system (BTMS) to maintain battery temperatures within a safe range and minimize the temperature variance between cells, thus improving battery safety .
Hence, a battery thermal management system, which keeps the battery pack operating in an average temperature range, plays an imperative role in the battery systems’ performance and safety. Over the last decade, there have been numerous attempts to develop effective thermal management systems for commercial lithium-ion batteries.
Proposed a liquid cooling strategy that adjusts the coolant flow rate and inlet temperature by monitoring the PCM and ambient temperatures, which improves the thermal performance of battery packs under varying environmental conditions. Yuqian Fan et al. .
When the operating temperature of the battery passes the safe range, the temperature control system gives feedback to the heating and cooling management systems, which, in turn, can cool or heat the battery pack .
