Abstract
At least one embodiment of the invention provides a multi-modal rechargeable battery pack that can switch between charging algorithms dynamically. This dynamic switching can be accomplished in a wide variety of ways, for example via external command or automatically. At least one embodiment of the invention provides a system that can switch a multi-modal rechargeable battery pack between one or more of a runtime mode, a lifespan mode, and a quick charge mode.
Claims14
An apparatus comprising:
- one or more processors;
- a multi-modal battery pack having one or more battery cells therein;
- and
- a program storage device housed within said multi-modal battery pack, the program storage device tangibly embodying a program of instructions that when executed by the one or more processors enables the multi-modal battery pack to:
- automatically determine an appropriate charging mode;
- and
- switch the one or more battery cells therein between charging modes, the charging modes comprising:
- a lifespan mode wherein the one or more battery cells are fractionally charged;
- a runtime mode wherein the one or more battery cells are charged;
- and
- a quick charge mode wherein the one or more battery cells are charged in a compressed time period;
- said apparatus further comprising one or more battery powered components operatively connected to the multi-modal battery pack.
A multi-modal battery pack comprising:
- one or more battery cells;
- and
- a program storage device tangibly embodying a program of instructions, the program of instructions comprising:
- program instructions configured to switch the multi-modal battery pack between charging modes, the charging modes comprising:
- a lifespan mode wherein the one or more battery cells are fractionally charged;
- a runtime mode wherein the one or more battery cells are charged;
- and
- a quick charge mode wherein the one or more battery cells are charged in a compressed time period.
A tangible program storage device, readable by machine, embodying a program of instructions that when executed by a processor of the machine enables the machine to:
- switch a multi-modal battery pack having one or more battery cells therein between charging modes, the charging modes comprising:
- a lifespan mode wherein the one or more battery cells are fractionally charged;
- a runtime mode wherein the one or more battery cells are charged;
- and
- a quick charge mode wherein the one or more battery cells are charged in a compressed time period.
