要約(日本語): In this paper, we investigated how much larger the power transmitter coil should be than the receiver coil for efficient charging when the position is shifted. When the receiver is placed on a pad-type charger and charged, the vertical displacement is small, but the horizontal displacement may be large. When the receiver coil diameter is 4 cm and the uniform distribution deviates by about 1 cm, a transmitter coil diameter of 7 to 8 cm is suitable because the coupling coefficient is almost constant. In addition, when the position varies due to random variables, it is shown that the transmitter coil diameter of 4.4 cm or 4.8 cm is suitable for the receiver coil diameter of 4 cm.
