Ibeos, a company developing high-reliability spacecraft electronics, built and operated to maximize efficiency for developing new products and technologies has introduced a new radiation-tolerant 50V/kWHR battery.
The B50-1000 from Ibeos is a 1000-Watt-hour, 50-Volt lithium-ion battery module. It is a radiation-tolerant and fault-tolerant energy storage system. The battery comes with an aluminum and PEEK packaging that is rigid, thermally conductive, and enables robust mechanical and thermal spacecraft interfacing. The battery’s redundant thermistors and heaters allow for thermal control.
The battery’s Radiation-tolerant Battery Interface Electronics (BIE) provide a remove-before-flight inhibit in addition to over-voltage, overcurrent, and under-voltage protection. Typical cell temperature rises with a 2C discharge rate which is less than 15 degrees C.
The battery module has a Total Ionizing Dose (TID) of 30 kRad (Si) and a Single Event Effect rating LET greater than 55. It has a mass of less than 7.5 Kg and measures 84 x 252 x 280 mm. The battery assembly has passed qualification testing including thermal vacuum, random vibration, shock, and short-circuit survival.
