Abstract:
A variable magnetic field in which a power-supplying coil and a power supplying resonator exist is generated only by the power-supplying coil. Power-supplying coils 111 and 112 each of which generates a variable magnetic field due to the supply of a variable current via a first current path 141 on one coil end 141a side and a second current path 142 on the other coil end 142a side; resonance capacitors 151 which are provided on the first current path 141 and the second current path 142; and a power-supplying coil short-circuit mechanism 1313 which is able to cause at least one of the power-supplying coils 111 and 112 to function as a power supplying resonator by allowing the end portions 141a and 142a of the first current path 141 and the second current path 142 to short-circuit with each other are provided.

Abstract:
Recharging of a secondary battery within a short time after the battery is fully charged is prevented. A method of achieving this prevention includes: a charging step of charging a secondary battery 22 by external power until a charging amount of the secondary battery 22 becomes equal to a fully charged amount, while stopping a driving component; and a stop continuation step of stopping the charging of the secondary battery 22 by the external power and stopping a driving component 21 in a stop continuation period in which the charging amount of the secondary battery 22 decreases from the fully charged amount to a predetermined charging amount.
