Starting at Technology Readiness Level (TRL) 4, SpeedBat aims to develop a TRL7 ultra-lightweight and scalable battery pack for space and unmanned electric flying vehicle (UEFV) applications. It will be validated on a UEFV called S30 Speeder that will reach TRL5. This will be achieved by exploiting advances in metal additive manufacturing, while integrating electrical functionalities directly into the manufacturing process. This integration will include all electrical connections and necessary heating elements, significantly reducing integration time. The design process will also consider demisability and recyclability. In addition, SpeedBat’s design is easily scalable, allowing capacity extension through parametric design. The battery pack, which is expected to be commercialized two years after the completion of the project by Almatech, will allow easy replacement of defective cells, thus avoiding the need to replace the entire battery. The consortium is composed of three SMEs (ALM, SPEEDER, FINTEK), one university (AMRC) and one research center (CSEM).
