Summary

Ibeos offers a 28-Volt lithium-ion battery module that is a radiation tolerant, fault tolerant, and ISS compliant energy storage system that comes in four unique configurations available with 275, 550, 825 and 1100-Watt-hour capacity, respectively.

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.

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

This product is available internationally, free of ITAR export controls, and is currently undergoing certification by NASA.
