Abstract

A process and system to detect and provide notification of a potential effect of a thermal event related to a vehicle and a process for updating thermal event probability of a specific area based on an effect of a vehicle are provided. Identifying potential vehicle thermal events and determining their potential effect in order to provide information related to the risk to both vehicle occupants and the proper authorities facilitates providing alerts and possible evacuation routes, and facilitates authorities providing the proper response. A vehicle is identified and information related to the identified vehicle, as well as information related to an area and an existing thermal event, are obtained and probability of a thermal event starting or potential spread of an existing thermal event is determined based on the obtained information and the potential is addressed before a thermal event starts or an existing thermal event spreads.

First claim

What is claimed is:

1. A non-transitory computer-readable storage medium embodying programmed instructions which, when executed by a processor, are operable for performing a method to detect and provide notification of a potential effect of a thermal event (TE) related to a vehicle, the method comprising:
determining a first increased probability of a TE related to at least one vehicle within a specific area;
obtaining vehicle data of at least one vehicle that is located within the specific area;
when the first increased probability of the TE related to the vehicle is detected by the processor from the obtained vehicle data, obtaining area data related to flammability of the specific area from at least one camera located in the specific area of the TE related to the at least one vehicle;
determining at least a second increased probability of occurrence of the existing TE or a third increased probability of spread of the existing TE within the specific area, the determination based on at least the first increased probability, the obtained vehicle data, and the obtained area data;
alerting at least one control point (CP) of the determined first increased probability, second increased probability and third increased probability;
determining that at least one user is located within the specific area, the at least one user utilizing a mobile application that provides a location of the at least one user; and
alerting the determined at least one user located in the specific area of the determined first increased probability, second increased probability and third increased probability and providing an evacuation route to the at least one user through the mobile application.

2. The non-transitory computer-readable storage medium of claim 1 , the method further comprising:
obtaining updated vehicle data from the at least one vehicle;
obtaining updated area data related to the flammability of the specific area;
determining an expanded specific area within which a potential TE may occur based on the updated vehicle data and updated area data;
determining a probability of an increase in spread of the potential TE; and
determining that at least one user is located within the expanded specific area, the at least one user utilizing a mobile application that provides a location of the at least one user;
alerting the determined at least one user located within the expanded specific area of the determined probability of the increase; and
alerting at least one CP of the determined expanded area and determined probability of the increase.

3. The non-transitory computer-readable storage medium of claim 2 , wherein the determined expanded specific area and the determined probability of the increase are related to an active TE or potential TE caused by a thermal runaway propagation (TRP) event.

4. The non-transitory computer-readable storage medium of claim 1 , wherein the obtained vehicle data is at least a fuel level of an internal combustion engine (ICE), a number of cells of an electric vehicle (EV) or a size of cells of an EV.

5. The non-transitory computer-readable storage medium of claim 1 , wherein the event related to the vehicle is a thermal runaway propagation (TRP) event of an electrical vehicle (EV) or a TE of an internal combustion engine (ICE).

6. The non-transitory computer-readable storage medium of claim 1 , wherein the determined at least one user located within the specific area is an occupant of the at least one vehicle.

7. The non-transitory computer-readable storage medium of claim 1 , wherein the determined at least one user located within the specific area is not an occupant of the at least one vehicle.

8. The non-transitory computer-readable storage medium of claim 1 , wherein the at least one CP is a weather service or a Public Service Answering Point (PSAP).

9. A system to detect and provide notification of a potential effect of a thermal event (TE) related to a vehicle, the system comprising:
a processor;
at least one camera located in a specific area including the vehicle;
a non-transitory computer-readable storage medium embodying programmed instructions which, when executed by the processor, are operable for performing a method, comprising:
a first probability detection function determining a first increased probability of a TE related to at least one vehicle within a specific area;
a first data collection function obtaining vehicle data of at least one vehicle that is located within the specific area;
when the first increased probability of the TE related to the vehicle is detected by the processor from the first data collection function, the processor performing:
a second data collection function, via the camera, obtaining area data related to flammability of the specific area;
a second probability detection function determining at least a second increased probability of occurrence of a TE or a third increased probability of spread of an existing TE within the specific area, the determination based on at least the first increased probability, the obtained vehicle data, and the obtained area data;
a first alert function alerting at least one control point (CP) of the determined first increased probability, second increased probability and third increased probability;
a mobile application detection function determining that at least one user is located within the specific area, the at least one user utilizing a mobile application that provides a location of the at least one user;
a second alert function alerting the determined at least one user located within the specific area of the determined first increased probability, second increased probability and third increased probability and providing an evacuation route to the at least one user through the mobile application.

10. The system of claim 9 , wherein:
the first data collection function further obtains updated vehicle data from the at least one vehicle;
the second data collection function further obtains updated area data related to the flammability of the specific area;
the first probability detection function further determines an expanded specific area within which a potential TE may occur based on the updated vehicle data and determines a probability of an increase in spread of the potential TE;
the first alert function further alerts the at least one CP of the determined expanded area and determined probability of the increase; and further comprising:
a mobile application detection function determining that the at least one user is located within the expanded specific area, the at least one user utilizing a mobile application that provides a location of the at least one user; and
a second alert function alerting the determined at least one user located within the expanded specific area of the determined first increased probability, second increased probability and third increased probability.

11. The system of claim 10 , wherein the determined expanded specific area and the determined probability of the increase in spread is related to an active TE or potential TE caused by a thermal runaway propagation (TRP) event.

12. The system of claim 9 , wherein the obtained vehicle data is at least a fuel level of an internal combustion engine (ICE), a number of cells of an electric vehicle (EV) or a size of cells of an EV.

13. The system of claim 9 , wherein the event related to the vehicle is a thermal runaway propagation (TRP) event of an electrical vehicle (EV) or a TE of an internal combustion engine (ICE).

14. The system of claim 9 , wherein the determined at least one user located within the specific area is an occupant of the at leas
