Secure power supply for an industrial control system

An industrial control system, comprising:

• a communications backplane;
• a control module communicatively coupled to the communications backplane;
• an input/output module communicatively coupled to the control module via the communications backplane and configured to be controlled and monitored by the control module, the input/output module configured to at least one of receive input signals from a sensor or provide output signals for at least one of an actuator or a motor;
• and
• a controller communicatively coupled to the communications backplane, the controller configured to be communicatively coupled to a battery module, the battery module configured to serve as a power supply for the control module and the input/output module, the battery module including at least one battery cell and a battery monitor communicatively coupled to the at least one battery cell, the controller at least configured to:
• receive the at least one of battery cell operation information and battery cell status information from the battery monitor,
• implement diagnostics at a battery module level associated with the battery module based on the received at least one of the battery cell operation information and battery cell status information, and
• provide network access to the at least one of the battery cell operation information, the battery cell status information, and the implemented diagnostics via a controller communications interface.

A controller configured to be communicatively coupled to a battery module, the battery module including at least one battery cell and a battery monitor communicatively coupled to the at least one battery cell, the controller at least configured to:

• receive the at least one of battery cell operation information and battery cell status information from the battery monitor,
• implement diagnostics at a battery module level associated with the battery module based on the received at least one of the battery cell operation information and battery cell status information, and
• provide network access to the at least one of the battery cell operation information, the battery cell status information, and the implemented diagnostics via a controller communications interface,
• wherein the controller is configured to authenticate a unique security credential associated with the battery monitor before permitting full interoperability between the controller and the battery module.
