Cobham Electronics Aboard Juno

After a journey of nearly five years, NASA's JUpiter Near-polar Orbiter (Juno) spacecraft successfully arrived at Jupiter with Cobham's Battery Electronics Unit (BEU) onboard. Engineered by the Cobham Semiconductor Solutions business unit, part of the Cobham Advanced Electronic Solutions sector, the BEU provides autonomous balancing of power cells to a Lithium Ion (Li-Ion) battery. This enables Juno to manage its power with reduced size and weight as compared to previous solutions, thus allowing higher payload capacities. 

"Cobham congratulates NASA on this exciting milestone," said Jeff Hassannia, Senior Vice-President of Business Development and Technology for Cobham Advanced Electronic Solutions. "As Juno forges ahead into a treacherous radiation environment at Jupiter, we are proud to have played a role on this important mission. Cobham's BEU provides autonomous, dissipative and continuous cell balancing which helps to maximize available battery capacity, and therefore battery cycle life, throughout a spacecraft's mission."

Cobham's BEU is fully redundant and can be configured to work with any battery size and voltage. The BEU is fully space qualified, having achieved NASA and Department of Defense Technology Readiness Level 9 (TRL 9) and uses numerous Cobham Semiconductor Solutions components that are radiation hardened and boast an extensive space flight heritage. Cobham's BEU technology can also be tailored for non-space commercial and automotive applications.
