Description

本発明は、非接触充電システムに関する。本発明は、非接触充電システムにおいて使用される非接触充電器及び端末機器にも関する。本発明は、非接触充電方法にも関する。   The present invention relates to a contactless charging system. The present invention also relates to a contactless charger and a terminal device used in a contactless charging system. The present invention also relates to a non-contact charging method.

非接触充電システムは、非接触充電器に端末機器を置くだけで端末機器に内蔵された２次電池を充電することができる。   The non-contact charging system can charge the secondary battery built in the terminal device simply by placing the terminal device on the non-contact charger.

例えば、特許文献１には、非接触充電器が交流電流から得た電力に基づくエネルギーを出力する出力手段を有し、端末機器が、前記充電器の前記出力手段から出力されたエネルギーを、電気的に非接触状態にて伝達を受けて充電電力を発生する充電電力発生手段と、この充電電力発生手段より発生される電力により充電される２次電池を備える充電装置が記載されている。   For example, Patent Document 1 includes an output unit that outputs energy based on electric power obtained from an AC current by a non-contact charger, and the terminal device outputs energy output from the output unit of the charger. In particular, there is described a charging device including charging power generating means for receiving charging in a non-contact state and generating charging power, and a secondary battery charged with power generated by the charging power generating means.

In recent years, such a non-contact charging system has been increasingly applied to a mobile phone or the like having many charging opportunities.

特開平７−３９０７８号公報JP 7-39078 A

非接触充電システムにおいては、ほとんどの場合、非接触充電器と端末機器が一対一の関係にある。複数の異なる端末機器を持ち、且つ、それらが異なる充電電圧を必要とする場合、端末機器ごとに専用の非接触充電器を揃えなくてはならず、ユーザのコスト負担が大きくなってしまっていた。   In the non-contact charging system, in most cases, the non-contact charger and the terminal device are in a one-to-one relationship. When there are multiple different terminal devices and they require different charging voltages, a dedicated contactless charger must be provided for each terminal device, increasing the cost burden on the user. .

また、多くの種類の非接触充電器を持つと、誤って充電電圧が異なる端末機器を充電してしまい、事故が発生するおそれがあるという問題もあった。   In addition, when there are many types of non-contact chargers, there is a problem that terminal devices with different charging voltages may be accidentally charged, resulting in an accident.

共振型の電磁誘導充電器として、２次側の共振コンデンサの容量を変えることにより、出力電流値を変化させ、１つの充電器で種類の異なる２次電池への充電に対応するものも提案されているが、受電コイルに発生する誘導起電力の可変は意図されていない。   As a resonance type electromagnetic induction charger, one that changes the output current value by changing the capacity of the secondary side resonance capacitor and supports charging of different types of secondary batteries with one charger is also proposed. However, it is not intended to vary the induced electromotive force generated in the power receiving coil.

本発明は、このような実情を鑑みてなされたものであり、複数の互いに異なる充電電圧の端末機器を充電することができる非接触充電システムを提供する。また、本発明は、このような非接触充電システムに用いる非接触充電器及び端末機器と、非接触充電方法も提供する。   This invention is made | formed in view of such a situation, and provides the non-contact charge system which can charge the several terminal device of a mutually different charging voltage. Moreover, this invention also provides the non-contact charger and terminal device which are used for such a non-contact charge system, and the non-contact charge method.

本発明の非接触充電システムは、非接触充電器と端末機器とを含み、前記端末機器は、受電コイルと、２次電池とを備え、前記非接触充電器は、送電コイルと、充電対象の前記端末機器のＩＤを検出するＩＤ検出手段と、検出された前記端末機器のＩＤに基づいて該端末機器の前記受電コイルを介する前記２次電池への充電条件である充電電圧を生じる誘導起電力が発生するように前記送電コイルに印加する交流周波数を調整し、前記送電コイルにこの交流周波数を印加する制御手段とを備えることを特徴とする。   The contactless charging system of the present invention includes a contactless charger and a terminal device, and the terminal device includes a power receiving coil and a secondary battery, and the contactless charger includes a power transmission coil and a charging target. ID detecting means for detecting the ID of the terminal device, and an induced electromotive force that generates a charging voltage as a charging condition for the secondary battery via the power receiving coil of the terminal device based on the detected ID of the terminal device And a control means for adjusting the AC frequency applied to the power transmission coil so that the AC power is generated and applying the AC frequency to the power transmission coil.

前記非接触充電器は、前記端末機器のＩＤと該端末機器への送電のために前記送電コイルに印加する交流周波数とを関連付けて登録したデータベースを備え、前記制御手段は、前記データベースに登録されたデータに基づいて前記送電コイルに印加する交流周波数を決定するようにしてもよい。   The non-contact charger includes a database in which an ID of the terminal device and an AC frequency applied to the power transmission coil for power transmission to the terminal device are associated and registered, and the control unit is registered in the database. The AC frequency applied to the power transmission coil may be determined based on the data.

前記非接触充電器のＩＤ検出手段が前記端末機器のＩＤを検出しないか、検出されたＩＤが前記データベースに登録されていない場合、前記非接触充電器の制御回路は送電動作を行わないようにしてもよい。このようにして、端末機器の２次電池に充電に適さない電圧が印加されるのを防ぐことができる。   When the ID detection unit of the non-contact charger does not detect the ID of the terminal device or the detected ID is not registered in the database, the control circuit of the non-contact charger does not perform a power transmission operation. May be. In this way, it is possible to prevent a voltage unsuitable for charging from being applied to the secondary battery of the terminal device.

前記端末機器は、前記２次電池の充電が完了すると前記非接触充電器に送電停止信号を送信し、前記送電停止信号を受信した前記非接触充電器は、送電動作を停止するようにしてもよい。このようにして、端末機器の２次電池の過充電を防ぐことができる。   When the charging of the secondary battery is completed, the terminal device transmits a power transmission stop signal to the contactless charger, and the contactless charger that has received the power transmission stop signal stops the power transmission operation. Good. In this way, overcharge of the secondary battery of the terminal device can be prevented.

図２は、本発明の非接触充電システムにおける充電の手順を説明するフローチャートである。ステップＳ２０１において、ユーザによって端末機器２が非接触充電器１の所定の充電可能領域に載せられ、充電動作が開始される。   FIG. 2 is a flowchart for explaining a charging procedure in the non-contact charging system of the present invention. In step S201, the terminal device 2 is placed on a predetermined chargeable area of the non-contact charger 1 by the user, and a charging operation is started.

ステップＳ２０２において、端末機器２のＣＰＵ２４は、メモリ２５から端末機器２のＩＤを読み出し、送信部２２に供給する。送信部２２は、ＩＤを信号化して交流周波数に重畳し、受電コイル２１にこの交流周波数を有する交流電流を供給する。交流電流が流れる受電コイル２１からは、磁束が発生する。   In step S <b> 202, the CPU 24 of the terminal device 2 reads the ID of the terminal device 2 from the memory 25 and supplies it to the transmission unit 22. The transmitter 22 converts the ID into a signal and superimposes the ID on the AC frequency, and supplies an AC current having this AC frequency to the power receiving coil 21. Magnetic flux is generated from the receiving coil 21 through which an alternating current flows.

ステップＳ２０３において、端末機器２の受電コイル２１が発生した磁束が非接触充電器１の送電コイル１１を通過し、電磁誘導によって送電コイル１１には誘導起電力が生じ、送電コイル１１には、端末機器２の受電コイル２１に供給された交流電流の交流周波数と同じ交流周波数を有する交流電流が流れる。非接触充電器１の検出部１２は、この交流電流に重畳された端末機器２のＩＤを検出し、非接触充電器１のＣＰＵ１５に供給する。   In step S203, the magnetic flux generated by the power receiving coil 21 of the terminal device 2 passes through the power transmission coil 11 of the non-contact charger 1, and an induced electromotive force is generated in the power transmission coil 11 by electromagnetic induction. An AC current having the same AC frequency as the AC frequency of the AC current supplied to the power receiving coil 21 of the device 2 flows. The detection unit 12 of the non-contact charger 1 detects the ID of the terminal device 2 superimposed on the alternating current and supplies it to the CPU 15 of the non-contact charger 1.

ステップＳ２０４において、非接触充電器１のＣＰＵ１５は、メモリ１６を参照し、検出されたＩＤが記憶されているものであるかどうかを判定する。ＩＤが記憶されているものではない場合、充電を行わず、動作を終了する。   In step S204, the CPU 15 of the non-contact charger 1 refers to the memory 16 and determines whether or not the detected ID is stored. If the ID is not stored, charging is not performed and the operation is terminated.

検出されたＩＤが記憶されたものである場合、ステップＳ２０５において、非接触充電器１のＣＰＵ１５は、メモリ１６に格納されたデータベースから、当該ＩＤの端末機器２の２次電池２７への適切な充電電圧となるような誘導起電力が端末機器２の受電コイル２１に発生するような交流周波数を読み出し、制御部１４に供給する。   When the detected ID is stored, in step S205, the CPU 15 of the non-contact charger 1 selects an appropriate ID from the database stored in the memory 16 to the secondary battery 27 of the terminal device 2 having the ID. The AC frequency at which an induced electromotive force that becomes a charging voltage is generated in the receiving coil 21 of the terminal device 2 is read and supplied to the control unit 14.

ステップＳ２０６において、制御部１４は駆動部１３を制御し、供給された交流周波数の交流電流を送電コイル１１に流す。交流電流が流れる送電コイル１１からは、磁束が発生する。この際、非接触充電器１のＣＰＵ１５は、インジケータ１７を点灯させ、端末機器２への送電が開始したことをユーザに通知する。   In step S <b> 206, the control unit 14 controls the driving unit 13 to flow the supplied AC current having an AC frequency through the power transmission coil 11. Magnetic flux is generated from the power transmission coil 11 through which an alternating current flows. At this time, the CPU 15 of the non-contact charger 1 turns on the indicator 17 to notify the user that power transmission to the terminal device 2 has started.

ステップＳ２０７において、非接触充電器１の送電コイル１１が発生した磁束が端末機器２の受電コイル２１を通過し、電磁誘導によって受電コイル２１には誘導起電力が生じ、交流電流が流れる。充電制御部２３は、ＣＰＵ２４の指示に応じて、受電コイル２１から流れる交流電流をダイオード２６に流す。ダイオード２６は交流電流を平滑化し、２次電池２７に供給する。このようにして、端末機器２の２次電池２７の充電が開始される。この際、端末機器２のＣＰＵ２４は、インジケータ２８を点灯させ、充電が開始したことをユーザに通知する。   In step S207, the magnetic flux generated by the power transmission coil 11 of the non-contact charger 1 passes through the power reception coil 21 of the terminal device 2, and an induced electromotive force is generated in the power reception coil 21 by electromagnetic induction, and an alternating current flows. The charging control unit 23 causes an alternating current flowing from the power receiving coil 21 to flow through the diode 26 in accordance with an instruction from the CPU 24. The diode 26 smoothes the alternating current and supplies it to the secondary battery 27. In this way, charging of the secondary battery 27 of the terminal device 2 is started. At this time, the CPU 24 of the terminal device 2 turns on the indicator 28 to notify the user that charging has started.

ステップＳ２０８において、端末機器２のＣＰＵ２４は２次電池２７の充電が完了したことを検知すると、充電制御部２３に２次電池２７への電流の供給を停止させる。この際、端末機器２のＣＰＵ２４は、インジケータ２８を消灯させ、充電が終了したことをユーザに通知する。さらに、ＣＰＵ２４は、送信部２２に指示し、送電停止信号を重畳した交流周波数を有する交流電流を受電コイル２１に供給させる。交流電流が流れる受電コイル２１からは、磁束が発生する。   In step S208, when detecting that the charging of the secondary battery 27 is completed, the CPU 24 of the terminal device 2 causes the charging control unit 23 to stop supplying the current to the secondary battery 27. At this time, the CPU 24 of the terminal device 2 turns off the indicator 28 and notifies the user that the charging is finished. Further, the CPU 24 instructs the transmission unit 22 to supply the power receiving coil 21 with an alternating current having an alternating frequency on which the power transmission stop signal is superimposed. Magnetic flux is generated from the receiving coil 21 through which an alternating current flows.

ステップＳ２０９において、端末機器２の受電コイル２１が発生した磁束が非接触充電器１の送電コイル１１を通過し、電磁誘導によって送電コイル１１には誘導起電力が生じ、送電コイル１１には、端末機器２の受電コイル２１に供給された交流電流の交流周波数と同じ交流周波数を有する交流電流が流れる。非接触充電器１の検出部１２は、この交流電流に重畳された送電停止信号を検出し、非接触充電器１のＣＰＵ１５に供給する。ＣＰＵ１５は、制御部１４に指示し、駆動部１３が送電コイル１１に交流電流を供給するのを停止させる。この際、非接触充電器１のＣＰＵ１５は、インジケータ１７を消灯させ、端末機器２への送電が終了したことをユーザに通知する。   In step S209, the magnetic flux generated by the power receiving coil 21 of the terminal device 2 passes through the power transmission coil 11 of the non-contact charger 1, and an induced electromotive force is generated in the power transmission coil 11 by electromagnetic induction. An AC current having the same AC frequency as the AC frequency of the AC current supplied to the power receiving coil 21 of the device 2 flows. The detection unit 12 of the non-contact charger 1 detects the power transmission stop signal superimposed on the alternating current and supplies it to the CPU 15 of the non-contact charger 1. The CPU 15 instructs the control unit 14 to stop the driving unit 13 from supplying an alternating current to the power transmission coil 11. At this time, the CPU 15 of the non-contact charger 1 turns off the indicator 17 and notifies the user that power transmission to the terminal device 2 has been completed.

本発明の非接触充電システムにおいては、非接触充電器が、端末機器のＩＤと、該端末機器の２次電池を充電するのに最適な電圧を発生する誘導起電力が該端末機器の受電コイルに生じるような交流周波数とを関連付けて登録したデータベースを備え、端末機器が非接触充電器の充電可能領域に置かれると、端末機器が自己のＩＤを非接触充電器に送信し、非接触充電器は送信されたＩＤをデータベース中で検索し、対応する交流周波数を有する交流周波数を送電コイルに流すことによって端末機器に送電を行う。これによって、端末機器の受電コイルには２次電池を充電するのに最適な電圧を発生する誘導起電力が生じる。   In the non-contact charging system according to the present invention, the non-contact charger generates the optimum voltage for charging the terminal device ID and the secondary battery of the terminal device. If the terminal device is placed in the chargeable area of the non-contact charger, the terminal device transmits its own ID to the non-contact charger, and the non-contact charging is performed. The device searches the transmitted ID in the database and transmits power to the terminal device by flowing an AC frequency having a corresponding AC frequency through the power transmission coil. As a result, an induced electromotive force is generated in the receiving coil of the terminal device that generates an optimum voltage for charging the secondary battery.
