Efficient thermal regulation is critical for maintaining the performance and safety of lithium-ion batteries, especially under high current scenarios such as fast charging and discharging. This study presents the design and experimental evaluation of a hybrid Battery Thermal Management System (BTMS) based on a Thermoelectric Cooler (TEC) integrated with a water-cooled heat sink. A prismatic lithium iron phosphate (LiFePO₄) battery cell was tested under four scenarios, with and without active cooling. Results showed that the TEC-based system significantly reduced peak surface temperatures by over 18%, improved voltage stability by 5.5%, extended discharge time by 15 %, these findings highlight the system’s suitability for compact electric vehicles (2- and 3-wheelers), offering a low-cost, scalable, and reliable solution for battery thermal management.
