EKo-Lack - Energy-efficient concepts and technologies for lacquer-based heating systems in electric vehicles
Overview
Background & policy context:
In pure electric vehicles, the energy for heating the passenger compartment has to be taken from energy sources other than the waste heat of the internal combustion engine. If this energy is taken from the drive battery, this results in a reduction in the range of up to 50 %. Other concepts of an additional heating require complex additional equipment and tanks, which increase the weight of the vehicle.
Objectives:
In the EKo-Lack project concepts for heating a test vehicle with infrared radiant heaters have been developed and studied.
Methodology:
The work included the positioning of the elements, the design of an optimal control strategy and the specification of the different components of the heating system. Both, feasibility studies as well as experiments which were intended to optimize the structure of the heating elements and to keep the heat loss through the back side of the plates as low as possible, were performed. Furthermore, simulation models have been developed and used to investigate the positioning of the elements in the vehicle and to optimize them.
