AVL Thermal Lab™, For front load management testing
AVL released a video introducing its Thermal Lab™, which offers users the ability to frontload thermal management testing from the road to the rig using a model-based Hardware-in-the-Loop (HiL) approach.
The company say its tool can solve the target conflict of optimized passenger comfort. "This includes battery lifetime and system costs versus the driving range in an early development phase". In addition, the significant reduction of vehicle tests in wind tunnels and test tracks speeds up the development, reduces costs and could potentially save one prototype generation.
AVL say the testing methodology is based on highly dynamic conditioning systems. As a result, the entire thermal management system can be tested at the rig under real emulated driving and ambient conditions independent of vehicle prototypes and weather.
The units-under-test (UUT) is the entire vehicle thermal management system (VTMS), which includes the powertrain coolant circuits, the heating, ventilation and air conditioning (HVAC). This also consists of the thermal management control units enabling users to test the performance of their thermal system.
