Description
Priority 2 activities will only be initiated on the explicit request of at least one delegation.
The objective of this activity is to evaluate the added value of the potential use of Li-Ion capacitors in telecom spacecraft in terms of overall platform cost savings and weight reduction.
Targeted Improvements:
- A potential cost reduction of the overall platform may be possible.
- The use of Li-Ion capacitors may permit the design of energy storage systems with good power but lower mass and volume.
- This study will allow for competitiveness of European industry in the regime of energy storage systems by including Li-Ion capacitors in the portfolio.
Li-Ion capacitors are an emerging, new type of energy storage cell technology. As compared to the promising supercapacitor technology, this technology has not yet been evaluated in detail for the use in space applications. In order for the European industry to stay competitive, this energy storage technology should be included in the portfolio of the existing ones.
The aim of this activity is to evaluate commercially off the shelf Li-Ion capacitor cells and to study their potential fields of applications in telecommunication spacecraft. Possible applications for Li-Ion capacitors in telecom satellites could be fuse clearing, regulated bus ripple control, or memory supply.
The selected Li-Ion capacitors will be characterised in terms of electric performance and lifetime. Based on these results a storage system comprising a number of cells shall be designed, manufactured and tested. As the final step the impact of the use of Li-Ion capacitors at system level shall be evaluated.
