Abstract
A method for controlling a charger to charge a power source of an electronic device includes connecting the charger and the electronic device and determining whether the power source of the electronic device is to be charged. The method further includes, the electronic device, sending a first control signal to the charger to enable charging of the power source of the electronic device in response to determining that the power source is to be charged and sending a second control signal to the charger to disable charging of the power source of the electronic device in response to determining that the power source is not to be charged.

A method of an electronic device for controlling a charger, the electronic device including a power source, the method comprising:
- connecting the charger and the electronic device;
- determining whether the power source of the electronic device is to be charged;
- sending a first control signal to the charger to enable charging of the power source of the electronic device in response to determining that the power source is to be charged;
- and
- sending a second control signal to the charger to disable charging of the power source of the electronic device in response to determining that the power source is not to be charged.
A method of a charger for charging a power source of an electronic device, the method comprising:
- connecting the charger and the electronic device;
- receiving a control signal from the electronic device;
- and
- enabling or disabling power to the power source of the electronic device based on the received control signal.
A charger for charging a power source of an electronic device, the charger comprising:
- a connection port including at least one power line and an identification line;
- a power generator coupled to the at least one power line of the connection port;
- a switch coupled to the power generator, the switch enabling or disabling power provided to the connection port;
- and
- a voltage comparator connected to the identification line, the voltage comparator determining whether to cause the switch to enable or disable power provided to the connection port based on a control signal provided by the electronic device at the identification line.
