While the market share of electric vehicles is steadily increasing, one of the key factors still slowing their adoption is thelimited driving range. Besides the powertrain, the heating and air-conditioning systems are two of the most significantenergy consumers. It is therefore crucial to optimize their power consumption while also keeping an eye on passengercomfort.

Simulation offers a reliable and cost-effective way for engineers to investigate HVAC (heating, ventilation and airconditioning) concepts, develop control functions and analyze the interplay of various subsystems under climate conditions.

AVL has developed a system simulation solution which allows thermal engineers to model a wide range of different airconditioning systems and connect them to a cabin model. Merged with the powertrain and the thermal managementsystem, it is possible to simulate the temperature pull-down and heat-up, as well as the impact of the air conditioning systemon the energy consumption in the vehicle.
