Abstract

A computer that includes at least one processor and memory. The processor of the computer can be programmed to execute instructions stored on the memory that include controlling, based on a temperature, which of a plurality of power sources of a vehicle battery are coupled to a starter circuit during a vehicle ignition event.

Claims

1. A computer, comprising a processor and memory storing instructions executable by the processor, the instructions comprising, to:

receive sensor data from a temperature sensor;

using the sensor data, determine whether a temperature is less than a threshold; and

when the temperature is not less than the threshold, isolate from a starter, during a vehicle ignition event, a first of a plurality of power sources in a vehicle battery and provide via at least one other of the plurality, power to the starter, wherein the first of the plurality comprises lithium-type cells.

2. The computer of claim 1, wherein the battery comprises the sensor.

3. The computer of claim 1, wherein the battery comprises three different power sources coupled in parallel.

4. The computer of claim 3, wherein the three power sources include lithium-type cells, lead-acid-type cells, and ultracapacitor-type cells carried by an H7-sized container.

5. The computer of claim 1, wherein the battery comprises a switch, wherein the instructions further comprise, to:

actuate the switch to a first position based on a cold-start condition; and

actuate the switch to a second position based on a warm-start condition.

6. The computer of claim 5, wherein, in the second position, at least one of the plurality of power sources is coupled to the starter during the ignition event.

7. The computer of claim 5, wherein, in the second position, at least the first of the plurality is isolated from the starter during the ignition event.

8. A computer comprising a processor and memory storing instructions executable by the processor, the instructions comprising, to:

control, based on a temperature, which of a plurality of different power sources of a vehicle battery are coupled to a starter circuit during a vehicle ignition event, the plurality of different power sources packaged within an H7-sized vehicle battery container.

9. The computer of claim 8, wherein the instructions further comprise, to:

prior to controlling which of the plurality of different power sources are coupled to the starter circuit, receive sensor data from a temperature sensor.

10. The computer of claim 9, wherein the battery comprises the temperature sensor.

11. The computer of claim 8, wherein the battery comprises three different power sources coupled in parallel.

12. The computer of claim 11, wherein a first power source comprises lithium-type cells, a second power source comprises lead-acid-type cells, and a third power source comprises ultracapacitor-type cells.

13. The computer of claim 12, wherein each of the lithium-type cells, the lead-acid-type cells, and the ultracapacitor-type cells are carried by an H7-sized container.

14. The computer of claim 8, wherein the battery further comprises an isolation circuit comprising at least one switch, wherein the instructions further comprise, to:

control the at least one switch.

15. The computer of claim 14, wherein the instructions further comprise, to:

actuate the at least one switch to a first position based on a cold-start condition; and

actuate the at least one switch to a second position based on a warm-start condition.

16. The computer of claim 15, wherein, in the first position, at least three of the plurality of different power sources are coupled to the starter circuit during the ignition event.

17. The computer of claim 16, wherein the ignition event changes an engine state to ON.

18. The computer of claim 15, wherein, in the second position, at least one of the plurality of different power sources is coupled to the starter circuit during the ignition event.

19. The computer of claim 15, wherein, in the second position, at least one of the plurality of different power sources is isolated from the starter circuit during the ignition event.

20. The computer of claim 8, wherein the vehicle event is associated with a STOP-START mode in a vehicle.
