To effectively control the battery temperature at extreme temperature conditions, a thermoelectric-based battery thermal management system (BTMS) with double-layer-configurated thermoelectric coolers (TECs) is proposed in this article, where eight TECs are fixed on the outer side of the framework and four TECs are fixed on the inner side.
Liquid cooling introduces a temperature difference between the upper and lower regions of the cell, particularly evident under low cold plate temperatures and heightened at high charging rates. Thus, an effective thermal management system incorporating temperature gradient considerations is crucial for large-capacity batteries .
