A charge device for controlling an abnormal charge request is provided. The charge device includes a controller that interrupts a charge path, when power is applied and that determines whether a charge request is an abnormal charge request through a detour charge path and that controls to maintain interruption of the charge path, if the charge request is an abnormal charge request. The controller may be further configured to interrupt the detour charge path, in response to determining that the charge request is a normal charge request; connect the charge path; and supply a charge current to the charge path.

Charge device for battery charging and method thereof

A wireless charging method in a wireless charging system is provided. In the method, wireless charging is performed by providing wireless charging power to a charging circuit. When both a first communication signal and a second communication signal are detected while the wireless charging is performed, the wireless charging power is isolated from the charging circuit. The wireless charging power is isolated so that noise included in the wireless charging power is not provided to the charging circuit.

Method and apparatus for avoiding noise in non-contact charging system

An apparatus and method for controlling a key lock in a portable terminal are provided. The apparatus includes a keypad, a key buffer, and an input controller. The keypad has a plurality of key buttons and detects at least one key input. The key buffer temporarily stores input key information. The input controller stores the at least one key input, which is detected by the keypad, in the key buffer in a key lock state and determines if a combination of key inputs stored in the key buffer includes an unlock key combination.
