Abstract

Advance temperature control of charging station components is provided. A system can identify a first time at which an electric vehicle arrives at a charging station to charge the electric vehicle. The system can determine, based at least in part on the first time and a temperature of a component of the charging station, a second time prior to arrival of the electric vehicle at the charging station at which to activate a cooling system of the charging station. The system can provide an instruction to activate the cooling system at the second time to lower the temperature of the component of the charging station by the first time at which the electric vehicle arrives at the charging station to charge the electric vehicle.

First claim

What is claimed is:

1. A system, comprising:
one or more processors, coupled with memory, to:
identify a first time at which an electric vehicle arrives at a charging station to charge the electric vehicle;
determine, based at least in part on the first time and a temperature of a component of the charging station, a second time prior to arrival of the electric vehicle at the charging station at which to activate a cooling system of the charging station; and
provide an instruction to activate the cooling system at the second time to lower the temperature of the component of the charging station by the first time at which the electric vehicle arrives at the charging station to charge the electric vehicle.

2. The system of claim 1 , comprising the one or more processors to:
receive, via a network, an indication from the electric vehicle to establish a session to charge the electric vehicle; and
determine, responsive to the indication and based on a distance between the electric vehicle and the charging station, the first time at which the electric vehicle arrives at the charging station to begin the session.

3. The system of claim 1 , comprising the one or more processors to:
receive, via a network, an indication of a location of the electric vehicle;
select, based on the location, the charging station from a plurality of charging station; and
establish, based on a distance between the selected charging station and the electric vehicle, a session to begin to charge the electric vehicle at the first time.

4. The system of claim 1 , comprising the one or more processors to:
receive, via a sensor, an indication of a first value of the temperature of the component, the component comprising at least one of a power cable or power electronics;
compare the first value with a threshold established for the component; and
determine, based at least in part on a comparison of the first value with the threshold, to activate the cooling system at the second time.

5. The system of claim 1 , comprising the one or more processors to:
receive, via a sensor, an indication of an ambient temperature external to the charging station; and
determine, based at least in part on the first time, the temperature of the component, and the ambient temperature external to the charging station, to activate the cooling system at the second time.

6. The system of claim 1 , comprising the one or more processors to:
receive, from the electric vehicle via a network, an indication of a state of charge of a battery of the electric vehicle and a location of the electric vehicle;
select, based on the state of charge of the battery and the location of the electric vehicle, the charging station from a plurality of charging stations; and
predict, based on a distance between the selected charging station and the electric vehicle, the first time at which the electric vehicle arrives at the charging station.

7. The system of claim 1 , comprising the one or more processors to:
receive, from the electric vehicle via a network, an indication of a state of charge of a battery of the electric vehicle;
determine, based on the state of charge, an amount of power to charge the battery of the electric vehicle; and
establish, based on the amount of power to charge the battery, to activate the cooling system at the second time.

8. The system of claim 7 , comprising the one or more processors to:
receive a first value of the temperature of the component measured via a sensor;
determine, based on the amount of power to charge the battery, a second value of the temperature for the component less than the first value that increases a rate of charge of the charging station relative to the first value of the temperature; and
determine the second time at which to activate the cooling system based on the first value of the temperature, the second value of the temperature, and the first time of arrival.

9. The system of claim 8 , comprising the one or more processors to:
establish a rate of cooling of the cooling system based on the first value of the temperature, the second value of the temperature, and the first time of arrival; and
provide the instruction to activate the cooling system to cool at the established rate of cooling.

10. The system of claim 1 , comprising the one or more processors to:
instruct the charging station to present a notification at a third time that the charging station is reserved for the electric vehicle, the third time earlier than or equal to the second time at which the cooling system is instructed to activate.

11. The system of claim 1 , comprising the one or more processors to:
identify, based at least on an indication of location of the electric vehicle input into a model trained via machine learning, the first time; and
determine, based at least in part on the first time and the temperature of the component of the charging station input into the model, the second time.

12. The system of claim 1 , the one or more processors to:
access a model trained with machine learning and data comprising values of the temperature of the component, values of an ambient temperature external to the charging station, and metrics indicating performance of charging sessions of the charging station; and
determine, via the model and based on the first time, the second time at which to activate the cooling system.

13. The system of claim 12 , comprising the one or more processors to:
identify an amount of power to charge the electric vehicle;
identify a first value of the temperature of the component measured by a sensor of the charging station;
identify an ambient temperature external to the charging station;
determine, via the model and based on the amount of power, a second value of the temperature of the component configured to improve performance of charging relative to the first value; and
determine the second time at which to activate the cooling system and a rate of cooling of the cooling system via the model and based on the first time, the amount of power, the first value of the temperature of the component, the second value of the temperature of the component, and the ambient temperature.

14. A method, comprising:
identifying, by one or more processors coupled with memory, a first time at which an electric vehicle arrives at a charging station to charge the electric vehicle;
determining, by the one or more processors, based at least in part on the first time and a temperature of a component of the charging station, a second time prior to arrival of the electric vehicle at the charging station at which to activate a cooling system of the charging station; and
providing, by the one or more processors, an instruction to activate the cooling system at the second time to lower the temperature of the component of the charging station by the first time at which the electric vehicle arrives at the charging station to charge the electric vehicle.

15. The method of claim 14 , comprising:
receiving, by the one or more processors via a network, an indication from the electric vehicle to establish a session to charge the electric vehicle; and
determining, by the one or more processors, responsive to the indication and based on a distance between the electric vehicle and the charging station, the first time at which the electric vehicle arrives at the charging station to begin the session.

16. The method of claim 14 , comprising:
receiving, by the one or more processors via a network, an indication of a location of the electric vehicle;
selecting, by the one or more processors, based on the
