In this paper, we describe the specification of the rover MOVE (MOon VEhicle) with a mass of approximately 5 kg for lunar surface exploration, closely based on the development of the rover's Electrical Power System (EPS). Fundamental relations , such as the interaction of the Thermal Control System (TCS) and EPS on the performance of the rover, will be described. The rover design approach includes budgets for mass and power of the needed subsystems like On Board Computer (OBC), payload, radio, Vehicle Control Unit (VCU), Guidance Navigation and Control (GNC) and the arrangement and number of solar cells have been used. This makes the rover an ideal testbed for the performance of the EPS under realistic conditions. The described results are based on the DFKI's outcome of the project SEARCH , which ended in January 2022 and was a collaboration together with the Walter Kern GmbH
