KULI - Thermal Management Simulation Software

In the automotive industry it is from highest importance that energy is optimally and efficiently used at any operating condition of the vehicle. Therefore the main focus of vehicle engineers lays on the powertrain system, heating and air conditioning, as well as engine cooling to ensure safe operation. The software package KULI has a long tradition in simulating and optimizing the thermal management system for automotive applications. In future it is necessary to facilitate a holistic consideration of energy flows, which means that mechanical power, electric power and thermal power have to be simulated at the same time and optimized in parallel. For this simulation task KULI will effectively support the engineer in setting up system components and control strategies with the aim to optimize performance, comfort, and operating reliability in the vehicle.
