Abstract
A non-contact type power charger may include: a power transmitting device including a plurality of power transmitting coils transmitting power in a non-contact manner; and a power receiving device including a plurality of power receiving coils receiving the power in a non-contact manner to charge a plurality of battery cells, respectively connected to the plurality of power receiving coils, with the power, wherein the power transmitted to each of the plurality of power receiving coils is controlled depending on coupling coefficients between the plurality of power transmitting coils and the plurality of power receiving coils.
Claims26
A non-contact type charger comprising:
- a plurality of power transmitting coils transmitting power in a non-contact manner;
- and
- a power converting unit controlling the power transmitted by the plurality of power transmitting coils, 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 the power, and updating the coupling coefficients.
A non-contact type battery comprising:
- a plurality of power receiving coils receiving power in a non-contact manner;
- a charging control unit setting a coupling coefficient between each of the plurality of power receiving coils and a corresponding power transmitting coil, depending on a state of the power received by each of the plurality of power receiving coils, converting the received power into charging power, and updating the coupling coefficient;
- and
- a plurality of battery cells receiving the charging power from the charging control unit to be charged with the charging power.
A non-contact type power charger comprising:
- a power transmitting device including a plurality of power transmitting coils transmitting power in a non-contact manner;
- and
- a power receiving device including a plurality of power receiving coils receiving the power in a non-contact manner to charge a plurality of battery cells, respectively connected to the plurality of power receiving coils with the power,
- wherein the power transmitted to each of the plurality of power receiving coils is controlled depending on coupling coefficients between the plurality of power transmitting coils and the plurality of power receiving coils, and
- the coupling coefficients are updated under predetermined conditions.
A non-contact type power transmission method comprising:
- detecting power states of a plurality of power transmitting coils transmitting power in a non-contact manner and power states of a plurality of power receiving coils receiving the power transmitted by the plurality of power transmitting coils and transferring the power to a plurality of battery cells respectively connected thereto;
- and
- setting coupling coefficients between the plurality of power transmitting coils and the plurality of power receiving coils, depending on the detected power states.
