The hybrid power train is one solution reducing the noxious emissions of internal combustion engine driven cars. In sports cars, the optimized power train efficiency and enhanced performance characteristic of HEVs1 / PHEVs2 result in better acceleration, braking and racetrack performance. An increasing number of vehicles uses lithium-ion-batteries as its main electric power source. This battery technology gives a narrow thermal operations range, which has to be kept by the battery cooling system. By analysing the cooling system of a PHEV sports car, the thermal interaction of the battery and the cooling system is shown. The simulation model of the full vehicle is subdivided into individual simulation models and coupled via a middleware. These sub models include the thermal-electrical battery model, fluid cooling system model, refrigerant circuit model and the power train model. Particularly high-load cycles like racetracks can be modelled and analysed concerning the thermal validation of a vehicle concept.
