Title (EN) ELECTRONIC DEVICE, CHARGER, AND ELECTRONIC DEVICE CHARGING SYSTEM
(FR) DISPOSITIF ÉLECTRONIQUE, CHARGEUR ET SYSTÈME DE RECHARGE DU DISPOSITIF ÉLECTRONIQUE
(JA) 電子機器、充電器、及び電子機器充電システム
Abstract:
(EN) Disclosed is an electronic device capable of proximity contactless communication even before charging of a secondary battery is completed and capable of preventing the secondary battery from being overdischarged during proximity noncontact communication. The electronic device (2) uses as a power supply a secondary battery (28) contactlessly chargeable by a charger (3) and is capable of proximity contactless communication with the charger (3). When the voltage of the secondary battery (28) at the start of the charging is below a predetermined value (Va), the electronic device (2) repeats charging of the secondary battery (28) for a predetermined time (Tb1) while receiving power from the charger (3) through a contactless power-receiving secondary coil (22) and data communication for a predetermined time (Ta1). When the voltage is a predetermined value (Va) or more, the electronic device (2) repeats charging of the secondary battery (28) for a predetermined time (Tb2) while receiving power from the charger (3) through the contactless power-receiving secondary coil (22) and data communication for a predetermined time (Ta2) (>Ta1).
(FR) L’invention concerne un dispositif électronique pouvant établir une communication de proximité sans contact, même avant que la recharge d'une batterie secondaire ne soit terminée, et pouvant empêcher une décharge accélérée de la batterie secondaire au cours d'une communication de proximité sans contact. Le dispositif électronique (2) utilise comme source d'énergie une batterie secondaire (28) rechargeable sans contact par un chargeur (3) et pouvant établir une communication de proximité sans contact avec le chargeur (3). Lorsque la tension de la batterie secondaire (28), au début de la recharge, est inférieure à une valeur préétablie (Va), le dispositif électronique (2) reprend la recharge de la batterie secondaire (28) pendant une durée préétablie (Tb1) tout en étant alimenté par le chargeur (3) par l'intermédiaire d'une bobine secondaire alimentée sans contact (22) et par communication de données, pendant une durée préétablie (Ta1). Lorsque la tension présente une valeur préétablie ou supérieure, le dispositif électronique (2) reprend la recharge de la batterie secondaire (28) pendant une durée préétablie (Tb2) tout en étant alimenté par le chargeur (3) par l'intermédiaire de la bobine secondaire alimentée sans contact (22) et par communication de données, pendant une durée préétablie (Ta2) (>Ta1).
(JA)  本発明の課題は、二次電池の充電完了を待たずとも近接非接触通信を行うことができると共に、二次電池が近接非接触通信中に過放電状態に陥ることがない電子機器を提供することである。  非接触方式で充電する充電器(3)によって充電可能な二次電池(28)を電源として用い、かつ充電器(3)と近接非接触通信が可能な電子機器(2)であり、電子機器(2)は、充電開始時の二次電池(28)の電圧が所定値(Va)未満の場合、非接触受電二次コイル(22)で充電器(3)から電力の供給を受けて二次電池(28)に所定時間(Tb1)充電する充電処理とデータ通信を所定時間(Ta1)行う通信処理を繰り返し、所定値(Va)以上の場合、非接触受電二次コイル(22)で充電器(3)から電力の供給を受けて二次電池(28)に所定時間(Tb2)充電する充電処理とデータ通信を所定時間(Ta2)(>Ta1)行う通信処理を繰り返す。
