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:

generating, at a processor executing a vehicle battery data analysis service, a request to execute a load test at a vehicle;

transmitting, by the processor, the request to a vehicle diagnostic system that is located at the vehicle, wherein the vehicle diagnostic system is in communication with a load tester that is located at the vehicle;

obtaining, by the processor, diagnostic data generated by the vehicle diagnostic system, 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 the load tester 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; and

updating, by the processor, fleet data based upon the diagnostic data.

2. The method of claim 1, further comprising:

determining that failure of the battery is imminent based upon an analysis of the fleet data and the diagnostic data; and

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

3. The method of claim 1, wherein the diagnostic data further comprises location data that identifies a geographic location at which the vehicle is located, and environmental data that identifies ambient conditions at the location.

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

5. The method of claim 1, wherein the load tester comprises a receiver that obtains a battery identifier from the battery and provides the battery identifier to a data output that obtains a load from the load sensor.

6. The method of claim 5, wherein the receiver comprises a radio frequency identification receiver, and wherein the battery comprises a further radio frequency identification transmitter.

7. The method of claim 1, further comprising:

in response to determining that failure of the battery is imminent based upon an analysis of the fleet data and the diagnostic data, 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.

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

9. The method of claim 1, wherein the vehicle diagnostic system is configured to activate the relay in response to a determination that the vehicle is running.

10. 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

generating a request to execute a load test at a vehicle,

transmitting the request to a vehicle diagnostic system that is located at the vehicle, wherein the vehicle diagnostic system is in communication with a load tester that is located at the vehicle,

obtaining diagnostic data generated by the vehicle diagnostic system, 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 the load tester 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,

updating fleet data based upon the diagnostic data.

11. The system of claim 10, 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 based upon an analysis of the fleet data and the diagnostic data; and

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

12. The system of claim 10, 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 based upon an analysis of the fleet data and the diagnostic data, 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.

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

14. The system of claim 10, wherein the diagnostic data further comprises location data that identifies a geographic location at which the vehicle is located, and environmental data that identifies ambient conditions at the location.

15. The system of claim 10, wherein the vehicle diagnostic system is configured to activate the relay in response to a determination that the vehicle is running.

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

generating a request to execute a load test at a vehicle;

transmitting the request to a vehicle diagnostic system that is located at the vehicle, wherein the vehicle diagnostic system is in communication with a load tester that is located at the vehicle;

obtaining diagnostic data generated by the vehicle diagnostic system, 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 the load tester 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; and

updating fleet data based upon the diagnostic data.

17. The computer storage medium of claim 16, 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 based upon an analysis of the fleet data and the diagnostic data; and

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

18. The computer storage medium of claim 16, wherein the vehicle diagnostic system activates the relay.

19. The computer storage medium of claim 16, wherein the diagnostic data further comprises location data that identifies a geographic location at which the vehicle is located, and environmental data that identifies ambient conditions at the location.

20. The computer storage medium of claim 16, wherein the vehicle diagnostic system is configured to activate the relay in response to a determination that the vehicle is running.
