Abstract

A power supply is disclosed for an industrial control system or any system including a distributed power supply network. In embodiments, the power supply comprises: a battery module including a battery cell and a battery monitor configured to monitor the battery cell; and a self-hosted server operatively coupled with the battery module, the self-hosted server being configured to receive diagnostic information from the battery monitor and provide network access to the diagnostic information. In implementations, the diagnostics stored by the self-hosted server can be broadcast to or remotely accessed by enterprise control/monitoring systems, application control/monitoring systems, or other remote systems via a secured network (e.g., secured access cloud computing environment).

First claim

What is claimed is:

1. 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 includes a unique security credential, the security credential configured to be authenticated by the battery monitor before permitting full interoperability between the controller and the battery module.

2. The controller as recited in claim 1 , wherein the controller is configured to be encased by a protection layer that further encases the battery module, the protection layer defining a rigid encasement that is mountable in one or more orientations.

3. The controller as recited in claim 1 , wherein the diagnostic information comprises at least one of an operating voltage of the battery cell, an operating current of the battery cell, an electrical charge associated with the battery cell, or an age associated with the battery cell.

4. The controller as recited in claim 1 , wherein the security credential is one of an encryption key, a physical identification, a certificate, or an identification number.

5. The controller as recited in claim 1 , 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.

6. The controller as recited in claim 1 , wherein the controller is configured to connect to a communications backplane.

7. The controller as recited in claim 1 , wherein the controller is configured to communicatively couple to a plurality of battery modules.

8. The controller as recited in claim 1 , wherein the controller comprises a server configured to maintain data in a local memory.

9. The controller as recited in claim 1 , wherein the controller is configured to communicatively couple the battery module to a control module of an industrial control system.

10. 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.

11. The industrial control system as recited in claim 10 , wherein the controller is configured to be encased by a protection layer that further encases the battery module, the protection layer defining a rigid encasement that is mountable in one or more orientations.

12. The industrial control system as recited in claim 10 , wherein the diagnostic information comprises at least one of an operating voltage of the battery cell, an operating current of the battery cell, an electrical charge associated with the battery cell, or an age associated with the battery cell.

13. The industrial control system as recited in claim 10 , wherein the controller includes a unique security credential, the security credential configured to be authenticated by at least one of the control module, the input/module, or the battery monitor before permitting full interoperability between the controller and a respective one of the control module, the input/module, or the battery monitor authenticating the controller.

14. The industrial control system as recited in claim 13 , wherein the security credential is one of an encryption key, a physical identification, a certificate, or an identification number.

15. The industrial control system as recited in claim 10 , wherein the controller is configured to authenticate a unique security credential associated with at least one of the control module, the input/module, or the battery monitor before permitting full interoperability between the controller and a respective one of the control module, the input/module, or the battery monitor authenticated by the controller.

16. The industrial control system as recited in claim 15 , wherein the security credential is one of an encryption key, a certificate, or an identification number.

17. The industrial control system as recited in claim 10 , wherein the industrial control system is configured to receive electrical power from multiple sources.

18. The industrial control system as recited in claim 17 , wherein the controller is configured to communicatively couple to a plurality of battery modules.

19. The industrial control system as recited in claim 10 , wherein the controller comprises a server configured to maintain data in a local memory.

20. 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.
