Power Manager Application

Overview

The Power Manager Application is an OBC default application that monitors the PDU and manages power distribution and thermal control.

Data Input

Reads application configuration table
Direct data input from dedicated power I²C line
Takes in input from other applications for activating power for devices
Accepts input from the limit checker application in case of a detected fault

Data Output

Direct data output over dedicated power I²C line
Current power state and telemetry output over Power topic

Data Processing

Manages and stores current state of the PDU, ensuring that parameters (thermals, voltage, etc.) remain within acceptable limits
Monitors current power level of battery pack and determines if satellite needs to enter power saving mode
Checks if current parameters allow for a power bus to be enabled when requested
Determines when an acceptable power level is reached that allows for detumbling
