The NANOeps subsystem consists of a power control & distribution module coupled with a battery management module, featuring a scalable integrated battery pack (up to 172 Wh). This makes it one of the most advanced EPS available for nano and microsatellites platforms. The NANOeps includes active balancing to ensure exceptional lifespan and heating system for optimal protection of each battery cell. It is capable of supplying power through 23 independent channels, three of which are redundant. Additionally, the system features five dedicated deployment actuator interfaces, separation and remove before flight switches, and many other functionalities.

The comprehensive subsystem’s TM (currents, voltages, temperatures, etc.) and TC is provided over cold redundant CAN interface. The NANOeps is fully complaint with up to two NANOeps-AMPPT subsystems.
