Experience in the development of an effective thermal management system for the high-voltage battery of the vehicle

Abstract

For the effective operation of the vehicle, which includes a high-voltage battery (HVB), it is first necessary to understand what conditions it is designed for. There are a number of criteria for the selection of HVBs for vehicles. One of them is the thermal management system, which ensures the operation of a HVB in optimal temperature mode. In HVBs, it is necessary to maintain an optimum temperature for maximum efficiency and service life. The article discusses the preferred thermal management system of the main manufacturers of vehicles with HVB. The technical solutions, the applied designs and the development trends of the designs of the temperature control of HVBs are described. On the basis of the considered structures, operating conditions and prospects for the development of the market for such vehicles, the concept of creating an effective thermal management system for HVBs for projected vehicles has been proposed. A classification of the thermal management system of HVBs as part of a vehicle, depending on the climatic conditions of operation, is proposed. One of the developed variants of perspective designs of high-voltage batteries of a vehicle operated in a wide range of temperatures is presented.
