Abstract
The present disclosure relates to a free voltage adapter for charging, in which when the free voltage adapter is connected to a charging object for charging, a voltage required for charging the charging object is first predicted in advance, and after that, a voltage corresponding to the charging voltage of the charging object is supplied, thus with a single adapter, a plurality of different types of charging objects with different charging voltages can be charged simultaneously.
Claims7
A free voltage adapter for charging, comprising:
- a main body provided with two or more insertion holes on one side, a plug terminal inserted into an outlet on an other side of the main body, and a charging control circuit board provided therein;
- and
- a power cable in which when one end of the cable is detachably coupled to the insertion holes and an other end of the cable is connected to a charging object so that the one end is connected to the insertion holes, the charging object is charged by the main body in which the plug terminal is inserted into the outlet,
- wherein the plug terminal is replaced with a corresponding one according to a shape of the outlet,
- wherein a display for displaying a charging state is provided on one side of the main body, and
- wherein the charging control circuit board is configured to apply an AC signal having a single frequency to a battery of the charging object, measure an AC impedance of the battery, and predict a life of the battery using the measured AC impedance, and
- wherein the display is configured to display the predicted battery life.
