Introduction (problem statement and relevance). In the context of rapid development of the electric vehicle industry and increasing demand for environmentally friendly vehicles, the issues of efficiency and reliability of traction batteries become more and more relevant. One of the key factors affecting durability and performance of the batteries is their operating temperature. The electric vehicle traction battery thermal management (thermostatics) system allows maintaining optimal temperatures, which helps to extend the service life, enhance energy efficiency, and ensure operational safety of electric vehicles.

The purpose of this work is to study designs and parameters of electric vehicle traction battery thermal management systems, as well as to analyze influence of shapes of ducts, number of ducts, location of inlets and outlets, and other factors, on efficiency of thermal management systems using various cell form factors.

Methodology and research methods. Within the study, scientific papers on various methods and technologies used to maintain optimal battery temperatures have been reviewed. The existing approaches to thermal management, their advantages and disadvantages, as well as potential for improvement have been analyzed.

Scientific novelty and results. As a result of the research, parameters of heat exchangers which make it possible to increase efficiency of an electric vehicle traction battery thermal management system were determined. Various form factors of battery cells were taken into account, which made it possible to reveal optimal design solutions for different types of batteries.

Practical significance. The results obtained provide information on which type of heat exchanger shall be installed to reduce energy losses during heat removal from the electric vehicle traction battery. This will allow optimization of thermal management systems, improvement in their reliability and durability, and also reduction of operating costs.
