Abstract

Methods and systems for providing emergency heating in an electric vehicle (EV) running out of power are described herein. An on-board computer or mobile device in an EV may determine that an amount of charge remaining for powering the EV is below a threshold charge level. The on-board computer or mobile device may then route the remaining amount of charge to power a heating system in the EV to maintain a temperature in the EV above a threshold temperature level, and shut down power to other components within the EV.

First claim

What is claimed is:

1 . A computer-implemented method for providing emergency heating in an electric vehicle (EV) running out of power, the method comprising:
determining, by one or more processors in an EV, an amount of charge remaining for powering the EV; routing, by the one or more processors, at least some of the remaining amount of charge to power a heating system in the EV; and shutting down, by the one or more processors, power to at least one other component within the EV.

2 . The computer-implemented method of claim 1 , further comprising:
determining, by the one or more processors, a temperature outside of the EV; and routing, by the one or more processors, at least some of the remaining amount of charge to power the heating system in response to determining that the outside temperature is below a threshold temperature level.

3 . The computer-implemented method of claim 1 , wherein the EV has one or more autonomous operation features.

4 . The computer-implemented method of claim 3 , further comprising:
in response to determining that the amount of charge remaining for powering the EV is below a threshold charge level, sending, by the one or more processors, control signals to the EV to cause the EV to pull over to a side of a road.

5 . The computer-implemented method of claim 1 , further comprising:
determining, by the one or more processors, a duration until emergency services are expected to arrive; predicting, by the one or more processors, a maximum temperature that the heating system can maintain in the EV using the remaining amount of charge for the determined duration; and in response to determining that the maximum temperature is within a threshold range of a threshold temperature level, setting, by the one or more processors, the temperature in the vehicle to the maximum temperature.

6 . The computer-implemented method of claim 5 , further comprising:
in response to determining that the maximum temperature is not within the threshold range of the threshold temperature level: determining, by the one or more processors, a maximum duration that in which the heating system can maintain the threshold temperature level using the remaining amount of charge; and transmitting, by the one or more processors, a notification to the emergency services indicating the maximum duration.

7 . The computer-implemented method of claim 5 , wherein the threshold temperature level is based upon a temperature outside of the EV.

8 . The computer-implemented method of claim 7 , wherein the threshold temperature level is inversely proportional to the outside temperature.

9 . A computer system configured to provide emergency heating in an electric vehicle (EV) running out of power, the computer system comprising one or more local or remote processors, transceivers, and/or sensors configured to:
determine an amount of charge remaining for powering an EV; route at least some of the remaining amount of charge to power a heating system in the EV; and shut down power to at least one other component within the EV.

10 . The computer system of claim 9 , wherein the computer system is further configured to:
determine a temperature outside of the EV; and route at least some of the remaining amount of charge to power the heating system in response to determining that the outside temperature is below a threshold temperature level.

11 . The computer system of claim 9 , wherein the EV has one or more autonomous operation features.

12 . The computer system of claim 11 , wherein the computer system is further configured to:
in response to determining that the amount of charge remaining for powering the EV is below a threshold charge level, send control signals to the EV to cause the EV to pull over to a side of a road.

13 . The computer system of claim 9 , wherein the computer system is further configured to:
determine a duration until emergency services are expected to arrive; predict a maximum temperature that the heating system can maintain in the EV using the remaining amount of charge for the determined duration; and in response to determining that the maximum temperature is within a threshold range of a threshold temperature level, set the temperature in the vehicle to the maximum temperature.

14 . The computer system of claim 13 , wherein the computer system is further configured to:
in response to determining that the maximum temperature is not within the threshold range of the threshold temperature level: determine a maximum duration that in which the heating system can maintain the threshold temperature level using the remaining amount of charge; and transmit a notification to the emergency services indicating the maximum duration.

15 . The computer system of claim 13 , wherein the threshold temperature level is based upon a temperature outside of the EV.

16 . The computer system of claim 15 , wherein the threshold temperature level is inversely proportional to the outside temperature.

17 . A non-transitory computer-readable medium storing instructions thereon that, when executed by one or more processors in an electric vehicle (EV), cause the one or more processors to:
determine an amount of charge remaining for powering an EV; route at least some of the remaining amount of charge to power a heating system in the EV; and shut down power to at least one other component within the EV.

18 . The non-transitory computer-readable medium of claim 17 , wherein the instructions further cause the one or more processors to:
determine a temperature outside of the EV; and route at least some of the remaining amount of charge to power the heating system in response to determining that the outside temperature is below a threshold temperature level.

19 . The non-transitory computer-readable medium of claim 17 , wherein the EV has one or more autonomous operation features.

20 . The non-transitory computer-readable medium of claim 19 , wherein the instructions further cause the one or more processors to:
in response to determining that the amount of charge remaining for powering the EV is below a threshold charge level, send control signals to the EV to cause the EV to pull over to a side of a road.
