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 power supply, comprising:
a battery module comprising:
a battery cell; and
a battery monitor communicatively coupled to the battery cell and configured to retrieve at least one of battery cell operation information and battery cell status information from the battery cell; and

a controller communicatively coupled to the battery module and 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.

2. The power supply as recited in claim 1 , wherein the battery cell comprises a lithium-ion battery cell.

3. The power supply as recited in claim 1 , wherein the power supply comprises a plurality of battery modules, wherein each of the battery modules is configured to connect with another one of the battery modules by stacking.

4. The power supply as recited in claim 3 , wherein each one of the battery modules is encased by a respective battery module protection layer.

5. The power supply as recited in claim 4 , wherein the plurality of battery modules is encased by a battery pack protection layer.

6. The power supply as recited in claim 5 , further comprising a power supply protection layer that encases the plurality of battery modules and the self-hosted server, the power supply protection layer defining a rigid encasement that is mountable in one or more orientations.

7. The power supply 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.

8. A power supply network, comprising:
a first power supply;
a second power supply communicatively coupled to the first power supply, wherein each of the first and the second power supplies comprises:
a battery cell;
a battery monitor communicatively coupled to the battery cell and configured to retrieve at least one of battery cell operation information and battery cell status information from the battery cell; and
a controller communicatively coupled to the battery module and configured to:
receive at least one of the battery cell operation information and the 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.

9. The power supply network as recited in claim 8 , wherein the battery cell comprises a lithium-ion battery cell.

10. The power supply network as recited in claim 8 , wherein each power supply comprises a plurality of battery modules, wherein each of the battery modules is configured to connect with another one of the battery modules by stacking.

11. The power supply network as recited in claim 10 , wherein each one of the battery modules is encased by a respective battery module protection layer.

12. The power supply network as recited in claim 11 , wherein the plurality of battery modules is encased by a battery pack protection layer.

13. The power supply network as recited in claim 12 , wherein each power supply further comprises a power supply protection layer that encases the plurality of battery modules and the self-hosted server, the power supply protection layer defining a rigid encasement that is mountable in one or more orientations.

14. The power supply network as recited in claim 8 , 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.

15. An industrial control system, comprising:
a control module;
an input/output module communicatively coupled to the control module 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 and provide output signals for at least one of an actuator and a motor;
a power module for furnishing power to at least one of the control module and the input/output module; and
a power supply for distributing power to the power module, the power supply comprising:
a battery module comprising:
a battery cell;
a battery monitor communicatively coupled to the battery cell and configured to retrieve at least one of battery cell operation information and battery cell status information from the battery cell; and

a controller communicatively coupled to the battery module and configured to:
receive at least one of the battery cell operation information and the 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.

16. The industrial control system as recited in claim 15 , wherein the battery cell comprises a lithium-ion battery cell.

17. The industrial control system as recited in claim 15 , wherein the power supply comprises a plurality of battery modules, wherein each of the battery modules is configured to connect with another one of the battery modules by stacking.

18. The industrial control system as recited in claim 17 , wherein each one of the battery modules is encased by a respective battery module protection layer.

19. The industrial control system as recited in claim 18 , wherein the plurality of battery modules is encased by a battery pack protection layer.

20. The industrial control system as recited in claim 19 , further comprising a power supply protection layer that encases the plurality of battery modules and the self-hosted server, the power supply protection layer defining a rigid encasement that is mountable in one or more orientations.

21. The industrial control system as recited in claim 15 , 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.
