Concept development of an energy storage unit using high temperature superconducting coil for spacecraft power systems – SMESinSpace

Summary

      SMESinSpace project is addressing, for the first time in Romania, the issue of design and manufacture a High Temperature Superconducting Magnet Energy Storage System (HT SMES).
The project is structured in 3 stages starting from a Technology Readiness Level (TRL) 2 by formulating the High Temperature Superconducting Magnet Energy Storage (HT SMES ) concept and will evolve through TRL 3 by realizing and testing the experimental model, to TRL 4, which will be accomplished by validating the HT SMES proof of concept operated in a simulated environment by integrating it in a Hybrid Power Source (HPS) structured on those realized in the STAR project no. 89/2013. The input power will be provided by an area of PV panels, realizing so a real operating situation. The load supply will be provided by HT SMES – battery hybrid energy storage using an energy management strategy adapted from those elaborated in the same STAR project, and the HPS response to the load transients will be determined.
The focus on high density energy storage is linked to ESA’s planning to develop new Power Processing Units, especially dedicated to the Full Electric Propulsion Spacecraft, but also in an attempt to replace the rechargeable batteries with cleaner, lighter, less bulky and more efficient electricity storage devices.
