CURRENT-LIMITING BATTERY USAGE WITHIN A CORDED ELECTRONIC DEVICE
First Claim
1. A method of operating a corded electronic device, the method comprising:
- determining a magnitude of a first electrical current that is required for one or more components of the corded electronic device to perform one or more operations;
determining whether the magnitude of the first electrical current is greater than a current limit value associated with a second electrical current received by the corded electronic device from an external power source located outside of the corded electronic device; and
providing the first electrical current to the one or more components to perform the one or more operations, wherein providing the first electrical current comprises;
in the event the magnitude of the first electrical current is greater than the current limit value, providing the second electrical current in conjunction with a third electrical current received from a battery power source located within the corded electronic device to the one or more components as the first electrical current, andin the event the magnitude of the first electrical current is less than or substantially equal to the current limit value, providing the second electrical current to the one or more components as the first electrical current.

Abstract
This disclosure describes techniques for operating a corded electronic device in which a battery and a power control unit manage power draw from an external power source electrically coupled to the corded electronic device using a physical cord, such as a universal serial bus (USB) cable. The power control unit automatically supplements an electrical current continuously drawn by the corded electronic device from the external power source with an electrical current from the battery, when needed. Moreover, the power control unit operates to limit the current drawn from the external power source and the physical cord so as to ensure the current does not exceed any limitations or requirements associated with the external power source or the physical cord.
