Nanofluid thermoelectric cooler based advanced battery thermal management system for battery degradation mitigation in real driving cycles

Abstract

Thermal management systems are utilized to keep the battery temperature below a certain limit for safe and long-life operation in electric vehicles. A detailed look at the issue of battery health is very important. One different small-size thermal management system based on nanofluid and thermoelectric elements is investigated in this work to keep the battery pack temperature below 25 C. The two parameters, lithium-ion loss (LIL) and battery energy capacity fade (BECF) are introduced to assess the extent of battery degradation. The results of the system showed that the Peltier element is at 25 C and with the operation of the fan coil in the cycle and consumes less energy. In the study of
