Development of a promising temperature control system for electromobiles

Abstract

Introduction. The difficulties of operation in different climatic conditions are the main reasons that prevent widespreading of electromobile transport. These difficulties are caused mainly by the design features of such vehicles. First and foremost, they refer to the traction battery and its operation in conditions of low and elevated ambient temperatures. The purpose of this study was to develop conceptual and structural solutions to create universal cooling systems for electric vehicles, ensuring their effective operation in different climatic conditions. Methodology and research methods. The method of analytical study of the vehicle properties obtained on the basis of experimental data in various modes of its operation was used. Scientific novelty and results. A efficient temperature control system has been developed to make the operation of electric vehicles in a wide range of temperatures possible. The principle and the basic architecture of constructing thermal control of several vehicle components combined into one fluid circuit were described. Special attention was paid to the principle of automatic mode operation of the considered temperature control system, which provided the specified optimal temperature balance, regardless of different climatic and road conditions. Practical significance. The developed temperature control system was applied to an experimental electromobile. The article has presented the laboratory and road tests results concerning the performance of the developed temperature control system under various driving conditions. The obtained results confirmed the necessity to use implemented conceptual and layout solutions in temperature control systems of electromobile.
