Abstract
There is provided a non-contact type charger including: a plurality of power transmitting coils transmitting power in a non-contact manner; a plurality of switching units connected to the plurality of power transmitting coils, respectively, to switch power transmitted by corresponding power transmitting coils; and a switching control unit controlling power switching of the switching units, depending on coupling coefficients between each of the plurality of power transmitting coils and a plurality of power receiving coils which receive the power transmitted by the plurality of power transmitting coils to charge a plurality of battery cells connected thereto with power.
Claims12
A non-contact type charger comprising:
- a plurality of power transmitting coils transmitting power in a non-contact manner;
- a plurality of switching units connected to the plurality of power transmitting coils, respectively, to switch power to be transmitted by the plurality of power transmitting coils;
- and
- a switching control unit controlling power switching of the plurality of switching units, depending on coupling coefficients between each of the plurality of power transmitting coils and a plurality of power receiving coils which receive the power transmitted by the plurality of power transmitting coils to charge a plurality of battery cells connected to the plurality of power receiving coils.
A non-contact type charger comprising:
- a plurality of power transmitting units each including:
- a power unit supplying direct current (DC) power,
- a switching unit switching the DC power supplied by the power unit,
- a power transmitting coil transmitting the power in a non-contact manner, depending on the power switching of the switching unit,
- a detecting unit detecting a power state change of the power transmitting coil, and
- a control unit controlling the power switching of the switching unit by setting a coupling coefficient between the power transmitting coil and a power receiving coil, depending on a detection result of the detecting unit.
