Abstract

Embodiments are provided for dynamic management of charge. The techniques may involve charging, using a first charging rate, an energy storage element to an intermediate state of charge, wherein the energy storage element is interchangeable with an in-use energy storage element. The techniques may further involve responsive to at least an identification of an anomalous condition of a device powered by the in-use energy storage element, the anomalous condition resulting in the in-use energy storage element being discontinued from use, charging, using a second charging rate, the energy storage element to a target state of charge, wherein the second charging rate is different from the first charging rate.

Claims (30)

1. A processor-implemented method comprising:

charging, using a first charging rate, an energy storage element to an intermediate state of charge, wherein the energy storage element is interchangeable with an in-use energy storage element; and

responsive to at least an identification of an anomalous condition of a device powered by the in-use energy storage element, the anomalous condition resulting in the in-use energy storage element being discontinued from use, charging, using a second charging rate, the energy storage element to a target state of charge, wherein the second charging rate is different from the first charging rate.

2. The method of claim 1 , wherein the second charging rate is greater than the first charging rate.

3. The method of claim 1 , further comprising determining the first charging rate based on a determination that an amount of time remaining before reaching a first estimated readiness time is greater than an estimated charging time to charge the energy storage element to the intermediate state of charge from an initial state of charge prior to charging the energy storage element using the first charging rate.

4. The method of claim 3 , further comprising determining the second charging rate based on a comparison of a second estimated readiness time to an estimated charging time to charge the energy storage element to the target state of charge from the intermediate state of charge.

5. The method of claim 4 , wherein the second charging rate is determined based on the second estimated readiness time being earlier than the first estimated readiness time.

6. The method of claim 3 , wherein the first estimated readiness time represents a predicted charging duration of the energy storage element.

7. The method of claim 3 , wherein the first estimated readiness time is determined by averaging durations of previous charging cycles.

8. The method of claim 1 , wherein the device powered by the in-use energy storage element comprises an infusion device, and wherein the anomalous condition is at least one of: a low fluid condition, an occlusion condition, an insertion site condition, or any combination thereof.

9. A system comprising:

one or more processors; and

one or more non-transitory processor-readable media storing instructions which, when executed by one or more processors, cause performance of:

charging, using a first charging rate, an energy storage element to an intermediate state of charge, wherein the energy storage element is interchangeable with an in-use energy storage element; and

responsive to at least an identification of an anomalous condition of a device powered by the in-use energy storage element, the anomalous condition resulting in the in-use energy storage element being discontinued from use, charging, using a second charging rate, the energy storage element to a target state of charge, wherein the second charging rate is different from the first charging rate.

10. The system of claim 9 , wherein the second charging rate is greater than the first charging rate.

11. The system of claim 9 , wherein the instructions further cause performance of determining the first charging rate based on a determination that an amount of time remaining before reaching a first estimated readiness time is greater than an estimated charging time to charge the energy storage element to the intermediate state of charge from an initial state of charge prior to charging the energy storage element using the first charging rate.

12. The system of claim 11 , wherein the instructions further cause performance of determining the second charging rate based on a comparison of a second estimated readiness time to an estimated charging time to charge the energy storage element to the target state of charge from the intermediate state of charge.

13. The system of claim 12 , wherein the second charging rate is determined based on the second estimated readiness time being earlier than the first estimated readiness time.

14. The system of claim 11 , wherein the first estimated readiness time represents a predicted charging duration of the energy storage element.

15. The system of claim 11 , wherein the first estimated readiness time is determined by averaging durations of previous charging cycles.

16. The system of claim 9 , wherein the device powered by the in-use energy storage element comprises an infusion device, and wherein the anomalous condition is at least one of: a low fluid condition, an occlusion condition, an insertion site condition, or any combination thereof.

17. A processor-implemented method comprising:

charging, using a first charging rate, an energy storage element to an intermediate state of charge, wherein the first charging rate is determined based on a first estimated readiness time representing a predicted duration of a charging cycle; and

responsive to at least an identification of an anomalous condition of a device powered by an in-use energy storage element, the anomalous condition resulting in the in-use energy storage element being discontinued from use, charging, using a second charging rate that is greater than the first charging rate, the energy storage element to a target state of charge, wherein the second charging rate is based on a second estimated readiness time that is earlier than the first estimated readiness time.

18. The method of claim 17 , further comprising:

determining an updated amount of time remaining for charging the energy storage element to the target state of charge based on the second estimated readiness time; and

determining the second charging rate based on the updated amount of time remaining.

19. The method of claim 17 , wherein the second charging rate is selected based on the second estimated readiness time being earlier than the first estimated readiness time.

20. The method of claim 17 , wherein the target state of charge is determined based on historical discharge data associated with the energy storage element.
