ABSTRACT

Transient thermal characteristics modeling and simulation of electrical vehicle battery systems was carried out. A transient thermal model of battery systems was constructed. The electric and thermal characteristics of a single cell charge and discharge at 1C was simulated first. And then the temperature characteristics of battery systems under the WLTC (world light-vehicle test cycle) condition was studied. Results show that the model could reflect the temperature of cells in case of the SOC (state of charge) varies.
