Özet
In this experimental study, two cold plates included different channel geometries were evaluated for the battery thermal management system (BTMS) of battery modules used in electric vehicles. The cold plates were manufactured using a metal additive manufacturing (AM) process, and a methodology for their integration into battery modules was presented. The effects of coolant temperatures (5 degrees C, 15 degrees C, and 25 degrees C) and current levels (175 A and 285 A) on the thermal behaviour of the battery module were investigated under worst-case conditions. The results demonstrated that the dual separated channel cold plate provided lower maximum cell temperatures and improved temperature uniformity compared with the pin-fin design. Furthermore, decreasing the coolant temperature reduced the maximum cell temperature, while 15 degrees C provided a favourable balance between cooling effectiveness and operating conditions. The charging process was identified as the most critical thermal operating condition, producing higher cell temperatures than the discharging process. The findings indicate that the dual separated channel geometry represents a promising alternative to conventional pin-fin cold plate designs for lithium-ion battery modules and has strong potential for future pack-level BTMS applications.
