Abstract
A method is provided comprising: detecting a connection between an electronic device and a battery charger; transmitting to the battery charger a first request for at least one of a first voltage level and a first current level; receiving from the battery charger a signal; and charging a battery of the electronic device with the signal.
Claims18
A method in an electronic device, comprising:
- detecting a connection with a battery charger;
- transmitting to the battery charger a first request for at least one of a first voltage level and a first current level;
- receiving from the battery charger a signal, wherein the signal is either an echo of the first request, a list of supported signal characteristics, or NACK (Not Acknowledge);
- and
- charging a battery of the electronic device in response to the signal.
A method in a battery charger, comprising:
- detecting a connection with an electronic device;
- receiving from the electronic device a first request for one of a first voltage level and a first current level;
- detecting whether the battery charger is capable of outputting a signal having one of the first voltage level and the first current level;
- and
- in response to detecting that the battery charger is capable of outputting the signal having one of the first voltage level and the first current level, outputting one of the first voltage level and the first current level to the electronic device.
An electronic device comprising a processing circuitry configured to:
- detect a connection with a battery charger;
- transmit to the battery charger a first request for at least one of a first voltage level and a first current level;
- receive from the battery charger a signal, wherein the signal is either an echo of the first request, a list of supported signal characteristics, or NACK (Not Acknowledge);
- and
- charge a battery in response to the signal.
A battery charger comprising processing circuitry configured to:
- detect a connection with an electronic device;
- receive from the electronic device a first request for a first signal characteristic;
- detect whether the battery charger is capable of outputting a signal having the first signal characteristic;
- and
- in response to detecting that the battery charger is capable of outputting the signal having the first signal characteristic, output the signal to the electronic device.
