| Abstract: | It is crucial for the safety and life cycle of an electric vehicle to have efficient battery thermal management. In this study, a compact lightweight 18650 Li-ion battery module was designed and fabricated by using aluminum-finned copper tubes as basic structure components. PID algorithm was adopted as the control scheme of the electronic expansion valve used in the electric vehicle air-conditioning system. Experiment using two phase flow of refrigerant, R134a, to cool battery pack directly was conducted to investigate thermal management performance. The experimental results showed that the proposed battery thermal management system can control temperature change of the battery pack temperature effectively. In addition, by using the dynamic temperature PID algorithm control scheme, the maximum temperature difference among the batteries was less than 4oC and the maximum temperature within the battery pack was less than 36oC at 1 C discharged rate. |
