Abstract

This study analyzes and presents the impact of ambient temperature on the characteristics of lithium cells used in electric vehicles. Lithium cells with different chemical compositions from three leading manufacturers were investigated. The observed parameters include capacity, power, energy density, efficiency, and others. The experiment was conducted at four different temperatures, selected in accordance with standard operating conditions: - 20°C, 0°C, 25°C, and 40°C. The obtained results were compared, visualized in graphical and tabular form, and analytically calculated. Conclusions regarding the temperature impact on the electrochemical characteristics of the tested batteries are presented.

Keywords
