Cover Story: The development of autonomous battery electric vehicle concepts poses new challenges for the thermal management system. The computational power needed to enable autonomous vehicle operation results in high thermal loads. New interior designs with unconventional passenger arrangement and diverse use cases require changes to the heating, ventilation, and air conditioning (HVAC) system. Possible solutions include modified cooling system topologies, HVAC systems with novel sensors and control strategies, thermal comfort simulations, and thermoelectric heat pumps. These measures were implemented in the thermal management system of the collaboration project UNICARagil and are discussed in this paper. In the project funded by the Federal Ministry of Education and Research of Germany (BMBF), four autonomous battery electric vehicles are developed and built. View this paper
