Abstract

Abstract: A thermo-electric coupling numerical calculation on the heat generation characteristics of the battery module in an electric vehicle is conducted to study the effects of discharge rate, current I/O mode, bus-bar contact area and current I/O position on the current density and the temperature field of battery module. The results show that the discharge rate significantly affects the temperature rise and the heat exchange between bus-bar and cell, thus the analysis on battery heat generation in high current rate charge / discharge conditions should take the electro-thermal effects of bus-bar into consideration. An experimental study on the temperature rise in battery module under different discharge rates is carried out by using battery charge / discharge testing system and under an ambient temperature of 28.5℃, the highest temperature rise measured is basically consistent with the result of thermo-electric coupling numerical calculation, demonstrating that numerical simulation can well predict the temperature rise characteristics of bus-bar

Key words: bus-bars, battery module, current density, temperature field, thermoelectric coupling
