Ibeos offers 135-Wh, 28-Volt lithium-ion battery module that is a radiation tolerant, fault tolerant, and ISS compliant energy storage system.
The aluminum and PEEK packaging is rigid, thermally conductive, and enables flexible mechanical and thermal spacecraft interfacing. Thermistors and polyimide thermofoil heaters allow for thermal control. Radiation tolerant battery interface electronics (BIE) provide a remove-before-flight inhibit in addition to over-voltage, over-current, and under-voltage protection. The chassis design enables mechanical integration in either horizontal or vertical orientations. This battery module is compatible with 28-Volt power systems including the Ibeos 150-Watt SmallSat EPS.
Ibeos' acceptance and qualification testing includes cell capacity matching, temperature testing, and life testing to ensure their products are built to the highest standards.
The key features of this battery solution include:
- Kapton thermofoil heaters
- External aluminum surfaces treated with MIL-DTL-5541 Type II, Class 3 chem film
- Aluminum chassis and PEEK cell capture plates
- Positive temperature coefficient (PTC) overcurrent protection at each cell
