View Patent ↗An embodiment provides an apparatus, including: apparatus components; a battery pack comprising a high charge rate cell component, the battery pack supplying power to one or more of the apparatus components; a processor; and a memory device accessible to the processor and storing code executable by the processor to: apply a normal rate of charge to a cell component of the battery pack; accept user input to switch the normal rate of charge to a second rate of charge which is higher than the normal rate of charge; and apply the second rate of charge to the high charge rate cell component based on the user input. Other aspects are described and claimed.
1. An apparatus, comprising:
apparatus components;
a battery pack comprising a high charge rate cell component having a charge/discharge rate of greater than 1C and a normal charge rate cell component having a charge/discharge rate of less than 1C, the battery pack supplying power to one or more of the apparatus components;
a processor; and
a memory device accessible to the processor and storing code executable by the processor to:
apply a normal rate of charge to a cell component of the battery pack;
accept user input to switch the normal rate of charge to a second rate of charge which is higher than the normal rate of charge; and
apply the second rate of charge to the high charge rate cell component based on the user input.
2. The apparatus of claim 1 , wherein the apparatus includes a switching component that accepts the user input switching between the normal rate of charge and the high rate of charge.
3. The apparatus of claim 2 , wherein the switching component is selected from the group of switching components consisting of a graphical user interface having a switch interface therein and a mechanical switching component.
4. The apparatus of claim 1 , further comprising a display device;
wherein the code is further executable by the processor to display an indication on the display device regarding switching to the high rate of charge.
5. The apparatus of claim 4 , wherein the indication comprises an estimate of an impact of choosing the high rate of charge on lifespan of the battery pack.
6. The apparatus of claim 5 , wherein the estimate is a cumulative estimate.
7. The apparatus of claim 1 , wherein a cell component of the battery pack is selected from the group of high charge rate cell components consisting of a mixture of nickel, cobalt and aluminum; and manganese spinel.
8. The apparatus of claim 1 , wherein the normal charge rate component and the high charge rate component are both disposed within a cell of the battery pack.
9. The apparatus of claim 1 , wherein the normal charge rate component and the high charge rate component are disposed in separate cells of the battery pack.
10. The apparatus of claim 1 , wherein the apparatus is a device selected from the group of devices consisting of an information handling device, a power tool, and an automobile.
11. A battery pack, comprising:
a high charge rate cell component having a charge/discharge rate of greater than 1C;
a normal charge rate cell component having a charge/discharge rate of less than 1C;
a processor; and
a memory device accessible to the processor and storing code executable by the processor to:
apply a normal rate of charge to a cell component of the battery pack;
accept user input to switch the normal rate of charge to a second rate of charge which is higher than the normal rate of charge; and
apply the second rate of charge to the high charge rate cell component based on the user input.
12. The battery pack of claim 11 , wherein the battery pack includes a cell component selected from the group of high charge rate cell components consisting of a mixture of nickel, cobalt and aluminum; and manganese spinel.
13. The battery pack of claim 11 , wherein the normal charge rate component and the high charge rate component are both disposed within a cell of the battery pack.
14. The apparatus of claim 11 , wherein the normal charge rate component and the high charge rate component are disposed in separate cells of the battery pack.
15. A method, comprising:
displaying, on a display device of an apparatus, a graphical user interface, the graphical user interface having a switch interface therein for switching between a normal rate of charge and a higher rate of charge for charging a battery pack of the apparatus;
receiving, at the apparatus, user input to the graphical user interface selecting a switching option of the switch interface;
switching the charging of the battery pack from the normal rate of charge to the higher rate of charge, the battery pack including at least one high charge rate cell component having a charge/discharge rate of greater than 1C; and
applying the higher rate of charge to the at least one high charge rate cell component of the battery pack based on the user input;
wherein said battery pack comprises a normal charge rate cell component having a charge/discharge rate of less than 1C.
16. The method of claim 15 , further comprising displaying an indication on the display device regarding switching to the higher rate of charge.
17. The method of claim 16 , wherein the indication comprises an estimate of an impact of choosing the higher rate of charge on lifespan of the battery pack.
18. The method of claim 17 , wherein the estimate is a cumulative estimate.
