Thermal management has a high potential for improving fuel economy, reducing emissions and increasing efficiency of conventional, hybrid, electric and fuel cell vehicles. The wide experience at St. Valentin for engineering services in vehicle development allows us to continuously improve our KULI software for energy management simulation.

It’s still a main goal to keep all temperatures below certain limits to protect components against overheating. Moreover, it is essential e.g. for batteries to be operated in a certain temperature range for high efficiency and long lifetime. KULI can deal with all these challenges using appropriate simulation models of entire systems. 

Also, the air conditioning system with detailed simulation options for the refrigerant circuit, the heat pump mode and the hot gas cycle are covered by KULI. In hybrid vehicles the air conditioning system is often used to cool the traction battery. The ‘Chiller’ component is the important link between coolant and refrigerant circuits. Integrated optimization procedures help the user to find the best layout. To keep up with the latest trends in vehicle development, software and simulation procedures are continuously enhanced.
