Abstract

A system for managing rechargeable batteries for medical devices includes a charging station that holds and charges multiple batteries simultaneously and an idle time module that determines a battery idle time for one or more of the multiple batteries held in the charging stations, wherein the battery idle time indicates the duration that each respective battery has been fully charged and available for use. The system further includes a battery selection indicator for each of the multiple batteries, wherein the battery selection indicator is activated based on the battery idle time to identify that the respective battery should be selected for use.

Claims

1. A system for managing rechargeable batteries for medical devices, the system comprising:

a charging station that holds and charges multiple batteries simultaneously;

an idle time module that determines a battery idle time for one or more of the multiple batteries held in the charging station, wherein the battery idle time indicates the duration that each respective battery has been fully charged and available for use; and

a battery selection indicator for each of the multiple batteries, wherein the battery selection indicator is activated based on the battery idle time to identify that the respective battery should be selected for use.

2. The system of claim 1, further comprising a battery optimization module that:

calculates a battery optimization value based on the battery idle time and one or more of a battery conditioning status, a battery charge level, a battery capacity, a battery temperature; and

controls activation of the battery selection indicator based on the battery optimization value.

3. The system of claim 2, wherein each of the multiple batteries held in the charging station is associated with one battery selection indicator in the form of a battery selection light that variously illuminates based on the battery optimization value for the respective battery.

4. The system of claim 2, wherein each of the multiple batteries held in the charging station contains one idle time module and one battery optimization module.

5. The system of claim 2, wherein the charging station contains one battery selection indicator for each battery holding location, and wherein the battery selection indicator is controllable based on the battery optimization value for the battery in the holding location.

6. The system of claim 2, wherein the battery optimization module is contained in the charging station and receives the battery idle time from the idle time module in each of one or more of the batteries held in the charging station;

and

wherein the battery optimization module activates the battery selection indicator for each battery for which the battery idle time is longer than a threshold idle time.

7. The system of claim 6, wherein the battery optimization module compares the battery idle times of the batteries held in the charging station and controls the battery selection indicator to indicate a high priority for one or more of the batteries held in the charger having a longest battery idle time.

8. The system of claim 1, wherein the idle time module receives a battery conditioning status indicating that the battery is being conditioned and determines that the respective battery is not available for use.

9. The system of claim 1, wherein the idle time module receives a battery temperature, and determines that the respective battery is not available for use if the battery temperature is above a threshold high temperature or below a threshold low temperature.

10. The system of claim 1, wherein the battery optimization module is contained in the charging station and receives the battery idle time from the idle time module in each of one or more of the batteries held in the charging station;

and

wherein the battery optimization module activates the battery selection indicator for each battery for which the battery idle time is longer than a threshold idle time; and

wherein the battery optimization module compares the battery idle times of the batteries held in the charging station and controls the battery selection indicator to indicate a high priority for one or more of the batteries held in the charger having a longest battery idle time.

11. The system of claim 1, further comprising multiple charging stations, each having a station ID;

wherein each charging station is communicatively connected to a host network containing a battery management database;

wherein the battery management database stores a battery profile for each battery held by one of the multiple charging stations; and

wherein the battery profile contains battery idle times for the respective battery.

12. The system of claim 11, wherein each charging station updates the battery profile for each of the multiple batteries being held therein.

13. The system of claim 11, wherein each battery profile contains the station ID, a connection time, and a disconnection time for each charging station to which the respective battery has been held.

14. The system of claim 13, further comprising a battery management module in the host network, wherein the battery management module identifies batteries with an average idle time longer than a threshold average idle time.

15. A method of managing rechargeable batteries for medical devices, the method comprising:

receiving multiple batteries in a charging station;

charging each of the multiple batteries;

determining a charge completion time for each of the multiple batteries;

determining a battery idle time for each of the multiple batteries held in the charging station, wherein the battery idle time is based on the duration since the charge completion time; and

controlling a battery selection indicator for each of the multiple batteries based on the battery idle time for the respective battery, wherein the battery selection indicator is activated to identify that the respective battery should be selected for use.

16. The method of claim 15, wherein the battery selection indicator is a battery selection light that variously illuminates based on at least the battery idle time for the respective battery.

17. The method of claim 15, further comprising:

comparing the battery idle times of each of the batteries held in the charging station; and

controlling the battery selection indicator to indicate a high priority for one or more of the batteries held in the charger having a longest battery idle time.

18. The method of claim 15, further comprising:

calculating a battery optimization value based on the battery idle time and one or more of a battery conditioning status, a battery charge level, a battery capacity, a battery temperature; and

controlling the battery selection indicator based on the battery optimization value.

19. The method of claim 18, further comprising activating the battery selection indicator for each battery having a battery idle time longer than a threshold idle time.

20. The method of claim 18, further comprising:

comparing the battery optimization values of the batteries held in the charging station; and

controlling the battery selection indicator to indicate a high priority for one or more of the batteries held in the charger having a highest battery optimization value.
