Abstract

The present disclosure relates to methods and associated systems for charging exchangeable energy storage devices positioned in a device-exchange station. The method includes, for example, (1) receiving demand information; (2) determining a charging plan for the device-exchange station at least partially based on a state-of-charge (SoC) of each of the exchangeable energy storage devices positioned in the device-exchange station, the demand information, and an available power of the device-exchange station; (3) generating a charging command for each of the exchangeable energy storage devices based on the charging rule for each of the exchangeable energy storage devices; and (4) transmitting the charging commands to the device-exchange station.

First claim

The invention claimed is:

1. A method for charging exchangeable energy storage devices positioned in a device-exchange station, the method comprising:
receiving demand information for the device-exchange station;
determining a charging plan for the device-exchange station at least partially based on a state-of-charge (SoC) of each of the exchangeable energy storage devices positioned in the device-exchange station, the demand information, and an available power of the device-exchange station, the charging plan including at least one charging rule for each of the exchangeable energy storage devices positioned in the device-exchange station;
generating a charging command for each of the exchangeable energy storage devices based on the charging rule for each of the exchangeable energy storage devices; and
transmitting the charging commands to the device-exchange station.

2. The method of claim 1 , further comprising:
periodically updating the charging plan for the device-exchange station; and
updating the charging plan in response to the triggering event on the device-exchange station.

3. The method of claim 1 , further comprising customizing the at least one charging rule for each of the exchangeable energy storage devices based on a predetermined objective.

4. The method of claim 3 , further comprising adjusting the charging plan based on an economic condition.

5. The method of claim 1 , wherein the charging plan is determined at least partially based on a type of the energy storage devices of the device-exchange station.

6. The method of claim 5 , wherein the type of the device-exchange station includes a public type, a semi-private type, or a private type.

7. The method of claim 1 , wherein the charging command is generated at least partially based on a charger type of a charger positioned in the device-exchange station.

8. The method of claim 7 , wherein the charger type includes a one-versus-one type, a two-versus-one type, or a four-versus-one type.

9. The method of claim 1 , wherein the device-exchange station is a first device-exchange station, and wherein the method comprises:
determining the charging plan for the first device-exchange station at least partially based on a status of a second device-exchange station adjacent to the first device-exchange station.

10. The method of claim 9 , wherein the status of the second device-exchange station includes a normal status or a service-interrupted status, and wherein the service-interrupted status results from a maintenance event or a power outage.

11. The method of claim 1 , further comprising:
assigning a priority value to each of the exchangeable energy storage devices positioned in the device-exchange station; and
determining the charging plan for the device-exchange station at least partially based on the priority value and the demand information.

12. The method of claim 11 , wherein the priority value is determined based on the SoC of each of the exchangeable energy storage devices positioned in the device-exchange station.

13. The method of claim 1 , further comprising:
categorizing the exchangeable energy storage devices positioned in the device-exchange station into a first group, a second group, and a third group, wherein the first group includes the exchangeable energy storage devices that have more than an SoC threshold and that are not locked, and wherein the second group includes the exchangeable energy storage devices that have less than the SoC threshold and that are not locked, and wherein the third group includes the exchangeable energy storage devices that are locked; and
determining the charging plan for the device-exchange station at least partially based on numbers exchangeable energy storage devices in the first group, the second group, and the third group.

14. The method of claim 1 , wherein the demand information includes a first demand prediction for a first hour and a second demand prediction for a second hour following the first hour.

15. The method of claim 14 , further comprising:
assigning a priority value to each of the exchangeable energy storage devices positioned in the device-exchange station; and
determining the charging plan for the device-exchange station at least partially based on the priority value and the first demand prediction and the second demand prediction.

16. The method of claim 1 , wherein the at least one charging rule is determined based on one or more characteristics of the exchangeable energy storage devices, and wherein the one or more characteristics incudes a current temperature, battery manufacturing information, battery characteristic information, battery charging information or battery usage information.

17. The method of claim 1 , wherein the at least one charging rule includes a first charging rule or a second charging rule, and wherein the method further comprises determining whether to use the first charging rule or the second charging rule based on the demand information, where in the first charging rule corresponds to a first charging rate greater than a second charging rate corresponding to the second charging rule.

18. A server comprising:
a processor configured to—
receive demand information for a device-exchange station;
determine a charging plan for the device-exchange station at least partially based on a state-of-charge (SoC) of each of exchangeable energy storage devices positioned in the device-exchange station, the demand information, and an available power of the device-exchange station, the charging plan including at least one charging rule for each of the exchangeable energy storage devices positioned in the device-exchange station;
generate a charging command for each of the exchangeable energy storage devices based on the charging rule for each of the exchangeable energy storage devices; and
transmit, via a communication component, the charging commands to the device-exchange station.

19. The system of claim 18 , wherein the processor is configured to update the charging plan in response to a triggering event, and wherein the triggering event includes an exchange of the exchangeable energy storage devices positioned in the device-exchange station, a change to the available power, a change to the demand information, or a reservation for the exchangeable energy storage devices positioned in the device-exchange station.

20. A method for managing a device-exchange station, the method comprising:
receiving a plurality of predicted exchange demands for the device-exchange station;
determining a charging plan for the device-exchange station at least partially based on a state-of-charge (SoC) and a temperature of each of the exchangeable energy storage devices positioned in the device-exchange station, the plurality of predicted exchange demands, and an available power of the device-exchange station, the charging plan including at least one charging rule for each of the exchangeable energy storage devices positioned in the device-exchange station;
