With a new state-of-the-art cold chamber, Autoneum is further expanding its expertise and innovation in vehicle thermal management. The tests and measurements carried out in the chamber enable the company to optimize existing technologies as well as simulation and engineering services and to adapt them to the changing thermal requirements of electric vehicles (EVs). With its tailor-made thermal management systems, Autoneum Management AG, Winterthur/Switzerland, supports vehicle manufacturers in improving energy efficiency and thus battery performance and reach as well as driver comfort in electric cars.
The absence of heat from the internal combustion engine in electric vehicles as well as the impact of ambient temperature on the performance and lifetime of lithium-ion batteries are changing the requirements for vehicle thermal management. In addition, the energy from the battery is used not only to power the e-motor but also to thermally manage the battery itself and to warm and cool the car cabin by means of the heating, ventilation and air conditioning system.
To increase the thermal comfort of the occupants and at the same time ensure optimum battery performance, save energy and thus increase the car’s range, manufacturers are placing increasing emphasis on efficient overall thermal management of the vehicle. Thanks to the new cold chamber, Autoneum is now able to test, evaluate and optimize products and future innovation opportunities for optimizing the thermal management of e-cars even more efficiently.
The chamber can test both occupants’ subjective perception of thermal comfort and the performance of components and entire vehicles under controlled temperature conditions of up to -20°C.
The tests conducted in the chamber show how existing insulating components such as under battery shields, carpets and interior trim need to be optimized to further enhance the thermal management of the vehicle battery and cabin. The tests also provide valuable insights regarding the development and optimization of heated surfaces such as floor mats and door trim panels to improve thermal performance and driver comfort of electric vehicles.
