Abstract

This paper presents a thermal interface for cylindrical cells using busbar-integrated cooling channels. This interface is available due to the usage of a stand-alone refrigerant circuit for the thermal management of the battery. A stand-alone refrigerant circuit offers performance and efficiency increases compared to state-of-the-art battery thermal management systems. This can be achieved by increasing the evaporation temperature to the requirements of the li-ion cells and the usage of alternative refrigerants. The solution proposed in this paper is defined for electric two-wheelers as the thermal management of these vehicles currently is insufficient for fast charging where high heat losses occur.
