Abstract

Concepts and technologies are disclosed herein for a vehicle battery data analysis service. A processor can execute a vehicle battery data analysis service. The processor can generate a request to execute a load test at a vehicle and transmit the load request to a vehicle diagnostic system located at the vehicle. The processor can obtain diagnostic data generated by the vehicle diagnostic system. The diagnostic data can include test data that indicates a load of a battery of the vehicle and vehicle data that identifies the vehicle. The processor can update fleet data based upon the diagnostic data.

Claims

1. A method comprising:

obtaining, by a processor that executes a vehicle battery data analysis service, diagnostic data generated by a vehicle diagnostic system that is located at a vehicle, the diagnostic data comprising test data that indicates a load of a battery of the vehicle and vehicle data that identifies the vehicle, wherein the test data is obtained by the vehicle diagnostic system from a load tester that is located at the vehicle, wherein the load tester performs a load test while the vehicle is running, and wherein the load tester comprises a relay that, when activated, disconnects a vehicle alternator from a sensor loop that comprises a load sensor to allow load testing of the battery while the vehicle is running.

2. The method of claim 1, wherein the diagnostic data further comprises location data that identifies a geographic location of the vehicle when the load test is performed.

3. The method of claim 2, wherein the diagnostic data further comprises environmental data that identifies ambient conditions at the geographic location.

4. The method of claim 1, further comprising:

determining that failure of the battery is imminent; and

transmitting, directed to a fleet management entity, a report that indicates that the failure is imminent.

5. The method of claim 1, further comprising:

determining that failure of the battery is imminent; and

transmitting a warning for presentation at the vehicle, wherein the warning comprises an instruction not to stop the vehicle until the vehicle has reached a particular location.

6. The method of claim 5, wherein the particular location is associated with a repair facility.

7. The method of claim 5, wherein the particular location is associated with a parking facility.

8. The method of claim 1, wherein the load sensor measures the load of the battery and provides a signal indicating the load measured to a data output.

9. The method of claim 1, further comprising:

in response to determining that failure of the battery is imminent, transmitting, to a fleet management entity, a report that indicates that the failure is imminent, wherein the fleet management entity orders a repair of the battery and indicates, to the vehicle diagnostic system, that the battery is expected to fail.

10. The method of claim 1, wherein the vehicle diagnostic system activates the relay.

11. A system comprising:

a processor; and

a memory that stores computer-executable instructions that, when executed by the processor, cause the processor to perform operations comprising

obtaining diagnostic data generated by a vehicle diagnostic system that is located at a vehicle, the diagnostic data comprising test data that indicates a load of a battery of the vehicle and vehicle data that identifies the vehicle, wherein the test data is obtained by the vehicle diagnostic system from a load tester that is located at the vehicle, wherein the load tester performs a load test while the vehicle is running, and wherein the load tester comprises a relay that, when activated, disconnects a vehicle alternator from a sensor loop that comprises a load sensor to allow load testing of the battery while the vehicle is running.

12. The system of claim 11, wherein the computer-executable instructions, when executed by the processor, cause the processor to perform operations further comprising:

determining that failure of the battery is imminent; and

transmitting, directed to a fleet management entity, a report that indicates that the failure is imminent.

13. The system of claim 11, wherein the computer-executable instructions, when executed by the processor, cause the processor to perform operations further comprising:

determining that failure of the battery is imminent; and

transmitting a warning for presentation at the vehicle, wherein the warning comprises an instruction not to stop the vehicle until the vehicle has reached a particular location.

14. The system of claim 13, wherein the particular location is associated with a repair facility.

15. The system of claim 11, wherein the computer-executable instructions, when executed by the processor, cause the processor to perform operations further comprising:

in response to determining that failure of the battery is imminent, transmitting, to a fleet management entity, a report that indicates that the failure is imminent, wherein the fleet management entity orders a repair of the battery and indicates, to the vehicle diagnostic system, that the battery is expected to fail.

16. The system of claim 11, wherein the vehicle diagnostic system activates the relay.

17. A computer storage medium having computer-executable instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising:

obtaining diagnostic data generated by a vehicle diagnostic system that is located at a vehicle, the diagnostic data comprising test data that indicates a load of a battery of the vehicle and vehicle data that identifies the vehicle, wherein the test data is obtained by the vehicle diagnostic system from a load tester that is located at the vehicle, wherein the load tester performs a load test while the vehicle is running, and wherein the load tester comprises a relay that, when activated, disconnects a vehicle alternator from a sensor loop that comprises a load sensor to allow load testing of the battery while the vehicle is running.

18. The computer storage medium of claim 17, wherein the computer-executable instructions, when executed by the processor, cause the processor to perform operations further comprising:

determining that failure of the battery is imminent; and

transmitting a warning for presentation at the vehicle, wherein the warning comprises an instruction not to stop the vehicle until the vehicle has reached a particular location.

19. The computer storage medium of claim 18, wherein the particular location is associated with a repair facility.

20. The computer storage medium of claim 17, wherein the computer-executable instructions, when executed by the processor, cause the processor to perform operations further comprising:

determining that failure of the battery is imminent; and

transmitting, directed to a fleet management entity, a report that indicates that the failure is imminent.
