Abstract

A method of determining a vehicle battery temperature by a non-linear dynamic model based on the physical concepts of thermal transfer and a system identification technique. The battery temperature model uses several available physical measurements from the vehicle, including the engine coolant temperature, surrounding air temperature, vehicle speed and the engine fan on/off state. This method also includes the estimation of an initial value of battery temperature before starting the iteration process by the battery temperature prediction from the dynamic model.
