Abstract

Apparatuses, methods, and computer program products are disclosed for battery storage maintenance is disclosed. An apparatus includes a processor and a memory that stores code executable by the processor to determine one or more battery characteristics for at least one battery of the apparatus, the battery characteristics associated with a charge of the at least one battery. The code is executable by the processor to determine a storage period for the apparatus, the storage period defining a period of time where the apparatus is not in use. The code is executable by the processor to calculate a storage battery charge level based on the one or more battery characteristics and the storage period, the storage battery charge level comprising a minimum battery charge level that allows operation of the apparatus after the storage period without providing additional charge to the at least one battery during the storage period.

Claims (34)

1 . An apparatus comprising:

a processor; and

a memory that stores code executable by the processor to:

determine, via a battery characteristic module, one or more battery characteristics for at least one battery of the apparatus, the battery characteristics associated with a charge of the at least one battery;

determine, via a storage period module, a storage period for the apparatus, the storage period defining a period of time where the apparatus is not in use;

calculate, via a charge level module, a storage battery charge level based on the one or more battery characteristics and the storage period, the storage battery charge level comprising a minimum battery charge level that allows operation of the apparatus after the storage period without providing additional charge to the at least one battery during the storage period; and

set, via the charge level module that interfaces with firmware of the at least one battery and prior to the storage period, a maximum charge level of the at least one battery to the storage battery charge level, such that the at least one battery is prevented from being charged beyond the storage battery charge level.

2 . The apparatus of claim 1 , wherein the one or more battery characteristics comprises an age of the at least one battery of the apparatus.

3 . The apparatus of claim 1 , wherein the one or more battery characteristics comprises a maximum charge capacity of the at least one battery of the apparatus.

4 . The apparatus of claim 1 , wherein the one or more battery characteristics comprises a usage value of the at least one battery of the apparatus.

5 . The apparatus of claim 1 , wherein the storage period is defined by a user.

6 . The apparatus of claim 1 , wherein the storage period is defined by a system administrator.

7 . The apparatus of claim 1 , wherein the code is executable by the processor to set a standard battery charge level to the storage battery charge level for a threshold time period prior to a start of the storage period.

8 . The apparatus of claim 7 , wherein the threshold time period is at least two days.

9 . The apparatus of claim 1 , wherein the code is executable by the processor to provide a notification that the apparatus will not be operable at an end of the storage period based on the one or more battery characteristics.

10 . The apparatus of claim 9 , wherein the notification comprises charge information for the at least one battery based on the one or more battery characteristics.

11 . A method comprising:

determining, via a battery characteristic module, one or more battery characteristics for at least one battery of a device, the battery characteristics associated with a charge of the at least one battery;

determining, via a storage period module, a storage period for the device, the storage period defining a period of time where the device is not in use;

calculating, via a charge level module, a storage battery charge level based on the one or more battery characteristics and the storage period, the storage battery charge level comprising a minimum battery charge level that allows operation of the device after the storage period without providing additional charge to the at least one battery during the storage period; and

setting, via the charge level module that interfaces with firmware of the at least one battery and prior to the storage period, a maximum charge level of the at least one battery to the storage battery charge level, such that the at least one battery is prevented from being charged beyond the storage battery charge level.

12 . The method of claim 11 , wherein the one or more battery characteristics comprises an age of the at least one battery of the device.

13 . The method of claim 11 , wherein the one or more battery characteristics comprises a maximum charge capacity of the at least one battery of the device.

14 . The method of claim 11 , wherein the one or more battery characteristics comprises a usage value of the at least one battery of the device.

15 . The method of claim 11 , wherein the storage period is defined by a user.

16 . The method of claim 11 , wherein the storage period is defined by a system administrator.

17 . The method of claim 11 , further comprising setting a standard battery charge level to the storage battery charge level for a threshold time period prior to a start of the storage period.

18 . The method of claim 11 , further comprising providing a notification that the device will not be operable at an end of the storage period based on the one or more battery characteristics.

19 . The method of claim 18 , wherein the notification comprises charge information for the at least one battery based on the one or more battery characteristics.

20 . A program product comprising a non-transitory computer readable storage medium storing code, the code being configured to be executable by a processor to perform operations comprising:

determining, via a battery characteristic module, one or more battery characteristics for at least one battery of a device, the battery characteristics associated with a charge of the at least one battery;

determining, via a storage period module, a storage period for the device, the storage period defining a period of time where the device is not in use;

calculating, via a charge level module, a storage battery charge level based on the one or more battery characteristics and the storage period, the storage battery charge level comprising a minimum battery charge level that allows operation of the device after the storage period without providing additional charge to the at least one battery during the storage period; and

setting, via the charge level module that interfaces with firmware of the at least one battery and prior to the storage period, a maximum charge level of the at least one battery to the storage battery charge level, such that the at least one battery is prevented from being charged beyond the storage battery charge level.
