Abstract
A method selects one or a plurality of sets of values characterizing an electric power of a power source capable of powering a device coupled to the power source via a connection interface. The selection is carried out according to values, characterizing the power supplied by the power source, measured at the connection interface.
Claims23
A method, comprising:
- selecting at least one set of values characterizing an electric power of a power source capable of powering an electronic device coupled to the power source through a connection interface that is located within the power source,
- wherein the selecting includes:
- measuring a first temperature, by a first temperature sensor located proximate the connection interface;
- and measuring a second temperature, by a second temperature sensor located proximate a power element within the power source and external to the connection interface, the power element including at least one of a power switch, a rectification diode, or an inductive element of a switching converter.

A device, comprising:
- a connection interface configured to couple an electronic device to be powered and a power source, the connection interface being located within the power source;
- a first temperature sensor located proximate the connection interface and configured to periodically measure first temperature values characterizing an electric power of the power source;
- and
- a second temperature sensor located proximate a power element within the power source and external to the connection interface, the power element including at least one of a power switch, a rectification diode, or an inductive element of a switching converter, the second temperature sensor configured to periodically measure second temperature values characterizing the electric power of the power source,
- wherein the device is configured to select a set of values characterizing the electric power of the power source based on the measured first and second temperatures.

A device, comprising:
- a connection interface configured to be coupled to an electronic device, the connection interface being located within a power source and including:
- communication terminals;
- a voltage converter configured to receive a source voltage and configured to generate from the source voltage a converted voltage based on a control signal;
- and
- a control unit coupled to the voltage converter and to the communication terminals, the control unit configured to receive from the electronic device over the communication terminals information-indicating an electric power to be supplied to the electronic device, and the control unit further configured to communicate over the communication terminals with the electronic device to negotiate with the electronic device a power to be supplied to the electronic device;
- a first temperature sensor located proximate the connection interface and configured to periodically measure first temperature values characterizing an electric power of the power source;
- and
- a second temperature sensor located proximate a power element within the power source and external to the connection interface, the power element including at least one of a power switch, a rectification diode, or an inductive element of a switching converter, the second temperature sensor configured to periodically measure second temperature values characterizing the electric power of the power source,
- wherein the control unit is con inured to select a set of values characterizing the electric power of the power source based on the measured first, and second temperatures.
