Abstract: A method and system for controlling a temperature control system based on both system reliability and battery state is disclosed. Batteries may supply power to places where the power grid is unavailable. The batteries may be housed in containers, with the temperature and humidity of the containers being controlled using a temperature control system. The system and method disclosed may select the temperature setpoint and humidity setpoint in order to operate the batteries within prescribed temperature and humidity values, while considering both the state of health of the batteries (e.g., the battery state of charge) and the state of health of the temperature control system (e.g., the failure of the compressors). In this way, the batteries may be operated within prescribed limits while accounting for both the health of the batteries and the health of the temperature control system.
