METHODS AND SYSTEMS FOR EFFICIENT BATTERY CHARGING AND USAGE
First Claim
1. A method of charging a battery associated with a portable device, the method comprising:
- storing power rate data reflecting a value at which power is purchasable at a particular time;
determining whether a charge level associated with the battery is below a predetermined battery-power threshold;
if a power source is available to the battery for charging, enabling the power source to provide power to the battery for charging, when the charge level associated with the battery is below the predetermined battery-power threshold and the value of the power rate data is not above a predetermined amount.

Abstract
Battery charging methods and systems for devices that have rechargeable batteries provide an efficient way to know when to charge a device'"'"'s battery, and when to switch between the device'"'"'s battery and an external power source as the device'"'"'s power source. The methods and systems access thresholds for a plurality of power rates, obtain information about when different power rates are in effect and, after determining a current power rate based on the information, compare the threshold of the current power rate to the device'"'"'s battery'"'"'s charge level. Based on such a comparison, the methods and systems can determine whether the battery should be charged, and the methods and system can determine whether the device'"'"'s battery or an external power source should be used as the device'"'"'s power source.
