Abstract
A numerical analysis of the formation of temperature fields as a result of the Joule heat release in a segment of a typical lithium-ion battery has been carried out. Software packages ANSYS Electric and ANSYS Fluent were used. At mathematical modeling of convective and conductive mechanisms of heat transfer and the release of thermal energy during the passage of electric current through the material of the plates of the battery were taken into account. As a result of the numerical simulation, the electrolyte temperatures of the accumulator are established when passing currents close to the maximum permissible. Temperature distributions in the investigated region have been obtained.
