PHYSICAL KEY TO FACILITATE AN INACTIVE MODE FOR A STATE-OF-CHARGE INDICATOR WITHIN A BATTERY
First Claim
1. A battery, comprising:
- at least one battery cell stack including at least one battery cell;
a state-of-charge indicator coupled to said at least one battery cell to indicate an amount of charge remaining in said at least one battery cell; and
a physical key detachably coupled to said state-of-charge indicator to control a mode of operation of said state-of-charge indicator.

Abstract
The invention provides a system and battery including a state-of-charge indicator (SOCI) to monitor and display the amount of charge within the battery. The SOCI is capable of operating in a hibernate mode, an active mode, and/or a sleep mode. The battery may be manufactured, shipped and/or stored with the SOCI operating in a power-saving hibernate mode. The SOCI may exit the hibernate mode and begin operating in active mode if a physical key connected to the battery is removed. In addition, the SOCI may operate in a sleep mode while the battery is not being used to conserve power. Furthermore, the invention provides a method of making a battery including a SOCI to monitor and display the state of charge of the battery.

11. A method of making a device to indicate an amount of available charge in at least one battery cell comprising the steps of:
-
providing a battery with at least one battery cell;
coupling a state-of-charge indicator to said at least one battery cell within said battery, wherein said state-of-charge indicator comprises;
a ground signal;
a clock signal; and
circuitry coupling said ground signal and said clock signal; and
configuring said state-of-charge indicator to operate in a hibernation mode by coupling a detachable physical key to said ground signal and said clock signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A system to indicate a battery state of charge, comprising:
-
a battery, wherein said battery comprises;
at least one battery cell, a state-of-charge indicator coupled to said at least one battery cell to indicate an amount of charge remaining in said at least one battery cell, wherein said state-of-charge indicator comprises;
circuitry to operate said state-of-charge indicator in at least one of an active mode, a hibernate mode and a sleep mode, wherein said state-of-charge indicator operating in said sleep mode consumes less charge from said at least one battery cell than said state-of-charge indicator operating in said active mode, and said state-of-charge indicator operating in said hibernate mode consumes less charge from said at least one battery cell than said state-of-charge indicator operating in said sleep mode, and a physical key detachably coupled to said state-of-charge indicator to control a mode of operation of said state-of-charge indicator; and
an electronic device coupled to said battery. - View Dependent Claims (21, 22, 23)
