Abstract

A power system including a load terminal, a sensor, and an electronic processor. The load terminal is configured to electrically connect to a load device. The sensor is configured to sense an electrical characteristic of the load device. The electronic processor is configured to receive, via the sensor, the electrical characteristic of the load device, supply power, via the load terminal, to the load device, discontinue supply of power to the load device when the electrical characteristic of the load device crosses a predetermined threshold, and enter a standby mode upon discontinuing supply of power to the load device. Wherein when in standby mode the electronic processor, at predetermined time intervals, determines if the load device crosses the predetermined threshold a second time.

First claim

What is claimed is:

1. A power system comprising:
a load terminal configured to electrically connect to a load device;
a transceiver configured to receive, from the load device, a state of charge of the load device and a unique identifier to discern the load device from other load devices of the same model; and
an electronic processor configured to
receive, via the transceiver, the state of charge of the load device and the unique identifier,
determine a charging history based on the unique identifier,
determine a predetermined threshold based on the charging history of the load device,
supply power, via the load terminal, to the load device,
discontinue supply of power to the load device when the state of charge of the load device is at or above the predetermined threshold, and
enter a standby mode upon discontinuing supply of power to the load device, wherein when in standby mode the electronic processor, at predetermined time intervals, determines if the state of charge of the load device is below the predetermined threshold.

2. The power system of claim 1 , wherein the state of charge of the load device is at least one selected from a group consisting of a voltage, a current, and a resistance.

3. The power system of claim 1 , wherein the electronic processor is further configured to receive information corresponding to the load device.

4. The power system of claim 3 , wherein the information is at least one selected from a group consisting of a device type, a manufacture, and a model.

5. The power system of claim 1 , wherein the electronic processor is further configured to communicate, via a transceiver, with a server and receive, from the server, a charging command.

6. The power system of claim 1 , wherein the maximum charge time is received from the load.

7. The power system of claim 1 , wherein the maximum charge time is received from a server.

8. The power system of claim 1 , wherein the state of charge of the load device is a time series of data points.

9. A method of operating a load terminal electrically connected to a load device, the method comprising:
receiving, via a transceiver in communication with the load device, a state of charge of the load device and a unique identifier to discern the load device from other load devices of the same model;
determining, via an electronic processor, a charging history based on the unique identifier;
determining, via an electronic processor, a predetermined threshold based on the charging history of the load device;
supplying power to the load device;
discontinuing supply of power to the load device when the state of charge of the load device is at or above the predetermined threshold; and
entering a standby mode upon discontinuing supply of power to the load device, wherein when in standby mode the electronic processor, at predetermined time intervals, determines if the load device is below the predetermined threshold.

10. The method of claim 9 , wherein the state of charge of the load device is at least one selected from a group consisting of a voltage, a current, and a resistance.

11. The method of claim 9 , wherein the electronic processor is further configured to receive information corresponding to the load device.

12. The method of claim 11 , wherein the information is at least one selected from a group consisting of a device type, a manufacture, and a model.

13. The method of claim 9 , wherein the electronic processor is further configured to communicate, via a transceiver, with a server and receive, from the server, a charging command.

14. The method of claim 9 , wherein the maximum charge time is received from the load.

15. The method of claim 9 , wherein the maximum charge time is received from a server.

16. The method of claim 9 , wherein the state of charge of the load device is a time series of data points.
