Abstract

The present disclosure relates to systems, methods, and devices for controlling charging of vehicles, to avoid charging during charge-adverse time periods or during charge restriction events. This can advantageously reduce cost to vehicles owners, and or provide access to reward incentives. Further, power distribution entities (utility providers) advantageously have increased control over power distribution to avoid over-burdening of power distribution infrastructure. Further, systems and methods for determining or inferring whether a vehicle is connected to a charge station are described, which can be used to inform automatic restriction of vehicle charging.

First claim

What is claimed is:

1. A system for controlling power distribution to a plurality of vehicles, the system comprising:
at least one processor;
at least one non-transitory processor-readable storage medium communicatively coupled to the at least one processor;
a user interface device; and
a communication interface communicatively coupled to the at least one processor,
wherein the at least one non-transitory processor-readable storage medium has instructions stored thereon, which when executed by the at least one processor, cause the system to:
determine a quantity of the plurality of vehicles expected to be connected to respective charge stations during a first time period;
determine a quantity of preventable power usage by restricting charging of respective batteries of a set of vehicles of the plurality of vehicles during the first time period, from a first charge rate outside of the first time period to a second charge rate less than the first charge rate during the first time period;
present, by the user interface device, the determined quantity of preventable power usage;
present, by the user interface device, a user interface for initiation of a charge-restriction event where respective charge rate for a subset of vehicles of the set of vehicles is restricted to the second charge rate during the first time period;
process a user input received by the user interface device to initiate the charge-restriction event for the set of vehicles; and
in response to user input at the user interface device to initiate the charge restriction event, initiate the charge-restriction event during the first time period.

2. The system of claim 1 , wherein the instructions which cause the system to determine the quantity of the plurality of vehicles expected to be connected to respective charge stations during the first time period cause the system to:
determine, by the at least one processor, a quantity of vehicles which are presently connected to respective charge stations based on connection data indicative of connection between each vehicle of the plurality of vehicles and a respective charge station.

3. The system of claim 1 , wherein the instructions which cause the system to determine the quantity of the plurality of vehicles expected to be connected to respective charge stations during the first time period cause the system to:
estimate, by the at least one processor, the quantity of the plurality of vehicles based on historical connection data indicative of connection between each vehicle of the plurality of vehicles and a respective charge station.

4. The system of claim 1 , wherein:
the instructions further cause the system to communicate, to at least one vehicle of the plurality of vehicles, an option to restrict charging from the first charge rate to the second charge rate during the charge-restriction event; and
the subset of vehicles of the plurality of vehicles for which charge rate is restricted to the second charge rate during the first time period comprises vehicles for which a response is received by the system indicating acceptance of the charge-restriction event.

5. The system of claim 4 , wherein the instructions further cause the system to:
determine, by the at least one processor, prior to the first time period, an expected quantity of vehicles which will accept the option to restrict charging from the first charge rate to the second charge rate.

6. The system of claim 5 , wherein the instructions which cause the system to determine the expected quantity of vehicles which will accept the option to restrict charging cause the at least one processor to: determine the expected quantity of vehicles which will accept the option to restrict charging based on historical acceptance data which is indicative of previous restricting of charging by vehicles of the plurality of vehicles.

7. The system of claim 1 , wherein:
the instructions further cause the system to allocate a respective reward for a respective recipient associated with each vehicle in the subset of vehicles.

8. The system of claim 7 , wherein the instructions which cause the system to allocate the respective reward for the respective recipient associated with each vehicle of the subset of vehicles cause the system to: allocate each reward based on a quantity of energy which is saved during the charge-restriction event by the respective vehicle restricting charge rate to the second charge rate instead of enabling charging at the first charge rate.

9. The system of claim 1 , wherein an indication of the first time period is receivable via the user interface device.

10. The system of claim 1 , wherein the instructions further cause the system to determine the first time period, by determining a peak time period where the quantity of the plurality of vehicles expected to be connected to respective charge stations includes more vehicles than time periods outside of the peak time period.

11. The system of claim 1 , wherein the instructions which cause the system to determine the quantity of the plurality of vehicles expected to be connected to respective charge stations cause the at least one processor to: for each vehicle of the plurality of vehicles, determine that the vehicle is connected to a respective charge station when a charge port cover of the vehicle is open.

12. The system of claim 11 , wherein the instructions further cause the system to, for each vehicle in the plurality of vehicles:
receive respective charge data for the vehicle for a respective second time period in which the charge port of the vehicle has been open;
infer, by the at least one processor, that the vehicle is coupled to a respective charge station if the charge port cover of the vehicle is open and if the respective charge data is indicative of charging of a battery of the vehicle in the respective second time period; and
infer, by the at least one processor, that the vehicle is not coupled to the respective charge station if the charge port cover of the vehicle is not open or if the respective charge data is indicative of no charging of the battery of the vehicle in the respective second time period.

13. The system of claim 11 , wherein the instructions further cause the system to, for each vehicle in the plurality of vehicles:
receive respective movement data for the vehicle indicative of movement of the vehicle for a respective second time period in which the charge port cover of the vehicle has been open;
infer, by the at least one processor, that the vehicle is coupled to a respective charge station if the charge port cover of the vehicle is open and if the respective movement data is indicative of the vehicle not having moved in the respective second time period; and
infer, by the at least one processor, that the vehicle is not coupled to the respective charge station if the charge port cover of the vehicle is not open or if the respective movement data is indicative of the vehicle having moved in the respective second time period.

14. The system of claim 13 , wherein the respective movement data comprises data selected from a group consisting of:
positional data indicating position of the vehicle over time;
velocity data indicating movement speed of the vehicle; and
inertial data indicating acceleration of the vehicle.

15. The system of claim 1 , the instructions which cause the system to determine the quantity of the plurality of vehicles expected to be connected to respective charge stations cause the at least one processor to: for each vehicle of the plurality of vehicles, determine that the vehicle is connected to a respective charge st
