Summary

Ibeos offers energy storage solutions with a design life that exceeds other Smallsat and Cubesat products on the market today. Ibeos' products are designed with overvoltage, undervoltage, and overcurrent protections. The company's acceptance and qualification testing includes cell capacity matching, temperature testing, and life testing to ensure their products are built to the highest standards.

Ibeos’ 1000-Watt-hour, 50-Volt lithium-ion battery module is a radiation tolerant, fault tolerant energy storage system. The aluminum and PEEK packaging is rigid, thermally conductive, and enables flexible mechanical and thermal spacecraft interfacing. Two thermistor and four polyimide thermofoil heater 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. Typical cell temperature rise with a 2C discharge rate is <15 deg C.

The key features of this battery include:

  • Supports high power operation with >48A sustained discharge, 24A sustained charge currents
  • 1 kWhr lithium-ion battery
  • Radiation tolerant under/over-voltage and over-current protection
  • External aluminum surfaces treated with MIL-DTL-5541 Type II, Class 3 chem film
  • Integrated redundant heaters and thermistors

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