Electronic device and method of charging electronic device

A charger comprising:

• an acquiring unit configured to receive first information from an electronic device which transmits the first information to a charger at a preset time period, wherein the charger has a first parameter associated therewith;
• a processor configured to receive the first information from the acquiring unit and to determine a charge state of the electronic device by determining whether the first information is received or not in the preset time period;
• and
• the processor is further configured to adjust power supplied to the electronic device in response to an abnormal charge state of the electronic device determined by the processor, wherein the abnormal charge state is determined by a preset signal value indicated by a current charge parameter of the electronic device;
• wherein the acquiring unit is further operative to acquire second information of the electronic device, before supplying power to the electronic device, the second information indicating a second parameter of the electronic device and the second parameter comprises an identification, a manufacture name, and/or a type of the electronic device;
• the processor is further operative to determine whether the second parameter matches with the first parameter of the charger;
• and
• the processor is further operative to supply power to the electronic device in a preset manner in response to the second parameter mismatching with the first parameter;
• and
• wherein the processor is further operative to supply power to the electronic device in the preset manner that comprises;
• providing notifying information to indicate that the charger is supplying power to the electronic device with a first output current or a second output current, the first output current being greater than the second output current;
• determining which of the first output current and the second output current is supplied to the electronic device by the charger according to a selection operation by a user;
• and
• supplying power to the electronic device with the first output current or the second output current selected by the user.

An electronic device, comprising;

• a transmitting unit configured to transmit a first information to a charger at a preset time period;
• and
• a charging unit configured to obtain power supplied from the charger for charging, wherein the charger has a first parameter associated there therewith,
• wherein the transmitting unit is operative to transmit second information to the charger before the electronic device is charged by the charger, the second information indicating a second parameter of the electronic device and the second parameter comprises an identification, a manufacture name, and/or a type of the electronic device, and so that the charger supplies power to the electronic device in a preset manner in response to the second parameter mismatching the first parameter;
• wherein the preset manner comprises:
• providing notifying information to indicate that the charger is supplying power to the electronic device with a first output current or a second output current, the first output current being greater than the second output current;
• determining which of the first output current or the second output current is supplied to the electronic device by the charger according to a selection operation by a user;
• and
• supplying power to the electronic device with the first output current or the second output current selected by the user.

A computer readable storage medium embodied with a computer program instruction which, when executed by a processor of a computer, performs a method comprising:

• a charger receiving first information from an electronic device, wherein the charger has a first parameter associated therewith;
• the charger determining a charge state of the electronic device by determining whether the first information is received or not in the first preset time period and generating a first instruction in response to an abnormal charge state of the electronic device, wherein the abnormal charge state is determined by a preset signal value indicated by a current charge parameter of the electronic device;
• the charger adjusting power supplied to the electronic device based on the first instruction;
• the charger acquiring second information of the electronic device before supplying power to the electronic device, the second information indicating a second parameter of the electronic device and the second parameter comprises an identification, a manufacture name, and/or a type of the electronic device;
• the charger determining whether the second parameter matches with the first parameter of the charger;
• and
• the charger supplying power to the electronic device in a preset manner in response to the second parameter mismatching the first parameter;
• wherein the preset manner comprises:
• providing notifying information to indicate that the charger is supplying power to the electronic device with a first output current or a second output current, the first output current being greater than the second output current;
• determining which of the first output current and the second output current is supplied to the electronic device by the charger according to a selection operation by a user;
• and
• supplying power to the electronic device with the first output current or the second output current selected by the user.

A method of charging an electronic device at a preset time period, the method comprising:

• the charger acquiring information of the electronic device before supplying power to the electronic device, wherein the charger has a first parameter associated therewith and the information indicating a second parameter of the electronic device and the second parameter comprises an identification, a manufacture name, and/or a type of the electronic device;
• the charger determining whether the second parameter matches with the first parameter of the charger;
• and
• the charger supplying power to the electronic device in a preset way in response to the second parameter mismatching the first parameter;
• wherein the preset way comprises:
• providing notifying information to indicate that the charger is supplying power to the electronic device with a first output current or a second output current, the first output current being greater than the second output current;
• determining which of the first output current and the second output current is supplied to the electronic device by the charger according to a selection operation by a user;
• and
• supplying power to the electronic device with the first output current or the second output current selected by the user.
