Patent number: 9093857Abstract: When the charge level of a fully-charged rechargeable battery decreases due to quiescent power drain, in order to recharge it is necessary for the user to pick up and again place the mobile device in which the rechargeable battery is inserted onto a charging apparatus and issue instructions to start recharging. To address this issue, a charging controller applies control to disconnect a capacitor from a receiver coil with a switch in the case where the charge level of a rechargeable battery is equal to or greater than a given threshold value, and additionally applies control to connect the capacitor to the receiver coil with the switch in the case where the charge level of the rechargeable battery is less than the threshold value.Type: GrantFiled: October 18, 2012Date of Patent: July 28, 2015Assignees: Sony Corporation, Sony Mobile Communications Inc.Inventors: Daisuke Sakai, Kuniharu Suzuki, Katsuya Suzuki
