First Claim
Patent Images
1. An electronic device comprising:
- a battery charger to receive a voltage from an energy source, and to provide an output power; and
a controller to;
receive a voltage value of the energy source;
receive a current value from the battery charger;
determine a present power value based on the received voltage value and the received current value;
compare the present power value with a previous power value to determine if a difference between the present power value and the previous power value is greater than a threshold; and
if the difference is greater than the threshold, provide at least one control signal to the battery charger to change the output power of the battery charger.

Abstract
An electronic device may include a battery charger and a controller. The battery charger may receive a voltage from an energy source, and may provide an output power. The controller may receive a voltage value of the energy source, may receive a current value from the battery charger or the energy source, may determine a power value based on the received voltage value and the received current value, and may provide at least one control signal to the battery charger to change the output power of the charger.

5. A method of an electronic device comprising:
-
receiving, at a charger, a voltage from an energy source; providing an output power from the charger; receiving, at a controller, a voltage value of the energy source; receiving, at the controller from the charger, a current value to indicate an input current to the charger; determining, at the controller, a present power value based on the received voltage value and the received current value; determining if a difference between the present power value and a previous power value is greater than a threshold; if the difference is greater than the threshold, providing at least one control signal to the charger based on the determined present power value; and changing an output power of the charger based on the at least one control signal. - View Dependent Claims (6, 7, 8, 9, 10)

11. A machine-readable medium comprising one or more instructions that when executed on a controller to perform one or more operations is to:
-
determine a present power value of a charger based on a voltage value received from an energy source and a received current value that corresponds to an input current to the charger; determine that a difference between the present power value and a previous power value is greater than a threshold; and responsive to the determination that the difference is greater than the threshold, provide at least one control signal to the charger based on the determined present power value to change an output power of the charger. - View Dependent Claims (12, 13)
