【発明の属する技術分野】
本発明は、携帯電話器用充放電装置及び充電方法に関する。
【０００２】
【従来の技術】
従来、以下の▲１▼〜▲５▼のような携帯電話器等の充放電器が知られており、各々に問題があった。即ち、
▲１▼携帯電話器の充電器としては、商用電源に充電器を接続しその充電器に携帯電話器のバッテリを接続して長時間掛けて充電していた。そのため、充電器設置場所に携帯電話器が拘束されていた。
▲２▼携帯電話器に制御器を通じて乾電池を接続して充電するものはあったが、乾電池が消耗すると更に取り替えることが必要でコスト高になっていた。
▲３▼予備の携帯用バッテリを用意する例もあるが高価であり、サイクルの早い携帯電話器の予備電池の需要は少ない。
▲４▼電気二重層コンデンサを二次電池に変えて電源とし複数のコードレス機器を共通の充電器で充電するものも知られている（例えば、特許文献１参照）。しかし、携帯電話器の移動携行用に適さない。
▲５▼コードレス機器の電気二重層コンデンサと接続される充電用直流電源と、その直流電源と電気二重層コンデンサ間に並列に接続される充電用コンデンサを直流電源で充電しその充電された充電用コンデンサでもって電気二重層コンデンサに充電する技術は知られている（例えば上記特許文献１の請求項１参照）。しかし、充電用コンデンサに充電された電気エネルギを電気二重層コンデンサに移し変えるのみで携帯電話器の急速バッテリ充電には適さない。

【発明が解決しようとする課題】
このように従来の上記▲１▼〜▲５▼のいずれの充（放）電器も、携帯電話器用としては適切なものが知られていなかった。特に、従来の携帯電話器用充電器（上記▲１▼参照）は、商用電源をバッテリに見合う直流電圧に変換して、充電器と携帯電話器を接続して、一定時間を掛けて充電するため、バッテリが満充電になるまで携帯電話器の使用は制限されるという大きな欠点があった。特に、外出先で携帯電話器のバッテリの電力が無くなったとき、迅速容易にその携帯電話器に充電できる好適な充放電システム（装置・設備）が無く、不便であった。（なお、一部に、６０分〜９０分を掛けて充電する設置式充放電器は用いられている。）
【０００５】
そこで本発明の目的は、コンビニエンスストア等に定置式の大型の共用充放電器を設置し、常時充分な電気エネルギを蓄えておき、これに小型の携帯充放電器を次々と接続して、各携帯充放電器に高速充電し、その後、この携帯充放電器を共用充放電器から取り外し、携帯充放電器を携行したまま携帯電話器のバッテリに、十分な時間を掛けて充電する等の全く新しい使用方法を提案することにある。
【０００６】
【課題を解決するための手段】
上述の目的を達成するため、本発明に係る携帯電話器用充放電装置は、商用電源に接続される定置式共用充放電器と；接続状態で該共用充放電器から供給される電気エネルギを蓄える電気二重層コンデンサから成る蓄電部と、定電圧出力部を有し、さらに上記共用充放電器に接続分離自在であって、携帯可能な複数個の携帯充放電器と；を具備し、上記携帯充放電器の上記定電圧出力部を、携帯電話器のバッテリに接続分離自在に接続して充電するように構成した。
また、定置式共用充放電器は、コンビニエンスストア，ホテル，駅，公共場所に設置されるボックス型であり、コイン投入孔を有し、該コイン投入孔へコインが投入されたことを検知するセンサ・スイッチを設け、該センサ・スイッチの検知作動によって、接続状態の上記携帯充放電器の上記蓄電部へ電気エネルギを供給するように制御するＯＮ・ＯＦＦ制御手段を有している。
【０００７】
また、定置式共用充放電器は、商用電源からの交流電力を整流・降圧する電源部と、該電源部からの直流電力を蓄える蓄電池と、接続状態の携帯充放電器に対して定電力を供給するように制御する定電力制御部と、携帯充放電器が接続分離自在に接続される端子を、備えている。
また、携帯充放電器の上記蓄電部は、共用充放電器から供給される電気エネルギを蓄える複数の電気二重層コンデンサを、直列接続して構成されている。
また、共用充放電器から携帯充放電器の上記蓄電部へ充電のために流れる電流をＩ１ とすると共に、上記携帯電話器のバッテリを充電するために上記蓄電部から定電圧出力部へ流れる電流をＩ２ とすると、Ｉ１ ≫Ｉ２ となるように構成されている。特に、５≦Ｉ１ ／Ｉ２ ≦ ２００に設定するのが望ましい。
【０００８】
そして、本発明に係る携帯電話器への充電方法は、コンビニエンスストア，ホテル，駅，公共場所にボックス型の共用充放電器を設置し、電気二重層コンデンサを有する携帯充放電器を上記共用充放電器に接続すると共に上記共用充放電器にコインを投入して急速充電し、その後、上記携帯充放電器を上記共用充放電器から分離して携帯し、携帯中に上記携帯充放電器を携帯電話器に接続して、充電させる方法である。
【０００９】
【発明の実施の形態】
以下、実施の形態を示す図面に基づき、本発明を詳説する。
【００１０】
図１及び、図２に於て、１６はボックス型（箱型）の定置式共用充放電器であり、２０…は、ハンドバッグ、袋物、ポケット等に収納して携帯可能な（小型の）複数個の携帯充放電器を示す。
ボックス型の共用充放電器１６は、コンビニエンスストア，ホテル，（列車やバス等の乗物の）駅，公共場所に設置され、コイン投入孔１２を有し、また、携帯充放電器２０を接続するための差込口（端子）５を有している。
【００１１】
図１〜図４に於て、定置式共用充放電器１６は、商用電源１８に入力プラグ（接続端子部）１９を介して接続され、電源部１にて（１００Ｖ交流を） 例えば１２Ｖ直流に、整流・降圧され、制御部２を経て、蓄電池３に供給されて、電気エネルギが蓄えられる。定置式の共用充放電器１６としては、この蓄電池３は十分に大型のものを使用可能である。
【００１２】
４は定電力制御部であり、蓄電池３からの出力側に接続され、この定電力制御部４の出力側は前記端子（差込口）５に接続される。
前記コイン投入孔１２へコイン１３が投入されたことを検知するセンサ・スイッチ１４が共用充放電器１６のボックスＢ内に設けられる。このセンサ・スイッチ１４からのコイン検出信号Ｉ１４は前記定電力制御部４へ送られる。
そして、接続状態の携帯充放電器２０の蓄電部７へ電気エネルギを供給するように、この定電力制御部４によって制御される。
【００１３】
即ち、定置式共用充放電器１６は、センサ・スイッチ１４の検知作動によって、接続状態の携帯充放電器２０の蓄電部７へ、電気エネルギを供給するよう制御するＯＮ・ＯＦＦ制御手段３０を有しており、このＯＮ・ＯＦＦ制御手段３０は、上記センサ・スイッチ１４と、（上記検出信号Ｉ１４を送る）配線と、定電力制御部４とから、構成される。
【００１４】
要するに、定置式共用充放電器１６は、商用電源１８からの交流電力を整流・降圧する電源部１と、この電源部１からの直流電力を蓄える蓄電部３と、この蓄電部３への充電量を管理する制御部２と、接続状態の携帯充放電器２０に対して定電力を供給するように制御する定電力制御部４と、携帯充放電器２０が接続分離自在に接続される端子（差込口）５、及び、センサ・スイッチ１４等を、備えている。しかも、コイン１３の投入をセンサ・スイッチ１４が検知作動すると、携帯充放電器２０への電気エネルギを供給開始するように制御するＯＮ・ＯＦＦ制御手段３０を有する。
【００１５】
図１に於て、１５はＬＥＤランプや液晶等の充電管理表示部であり、ＯＮ・ＯＦＦ制御手段３０によるＯＮ・ＯＦＦの各表示、及び、携帯充放電器２０の蓄電部７への充電状態又は充電量を、この表示部１５に表示し、携帯充放電器２０の保持者は、この表示部１５に従って、接続端子６を差込口（端子）５から、分離すればよい。
なお、蓄電池３は固定ボックスＢ内に設置されているので、大型のバッテリ大容量のものを使用でき、しかも、電源部１及び制御部２によって、フロート充電を行って、常時、この蓄電池３を満充電状態で待機させることが、望ましい。
【００１６】
図３に於て、図１に示したコイン投入口１２の下方に続く（ボックスＢ内の）コイン通路３１を示し、樋状誘導部材３２をもってコイン通路３１を形成し、前記センサ・スイッチ１４はコ字状として樋状誘導部材３２を抱込状として付設されている。
【００１７】
携帯充放電器２０は、（薄い）扁平箱型ケース１７を有し、例えば、縦辺Ｌ１ が１０ｃｍ〜１５ｃｍ，横辺Ｌ２ が８ｃｍ〜１０ｃｍ），厚さＬ３ が ０．５ｃｍ〜３ｃｍの小型として、ハンドバッグやポケットやカバンに容易に収納して携帯可能な大きさ（サイズ）とする。この（携帯用）ケース１７から２本の細いコード３３， ３４が突設されている。一方のコード３３の先端には、前記端子５に接続分離自在に接続される（入力）端子６が設けられ、他方のコード３４の先端には、（出力）端子３５が付設される。
【００１８】
携帯充放電器２０は、端子５と端子６の接続状態で、共用充放電器１６から供給される電気エネルギを蓄える複数の電気二重層コンデンサ８…から成る蓄電部７と、定電圧出力部１０と、を備えている。
そして、この携帯充放電器２０の定電圧出力部１０を、携帯電話器Ｔのバッテリ１１に、接続分離自在に接続して充電可能である。具体的には、出力端子３５が携帯電話器Ｔの接続端子部３６に接続される。
【００１９】
図８と図４に示す如く、携帯充放電器２０の蓄電部７は、共用充放電器１６からの電気エネルギを蓄える複数の電気二重層コンデンサ８…を、直列接続して構成されている。つまり、この直列接続される二重層コンデンサ８…は、静電容量Ｃ１ ，Ｃ２ ………，Ｃｎ を有し、Ｖ１ ，Ｖ２ ，………，Ｖｎ は各端子電圧を示す。Ｅは蓄電部７の供給電圧であって、Ｅ＝Ｖ１ ＋Ｖ２ ＋………＋Ｖｎ （総電圧）に相当する。
【００２０】
図４に於て、端子５に端子６を接続し、共用充放電器１６から携帯充放電器２０の蓄電部７へ充電のために流れる電流をＩ１ とすると共に、その後の端子３５と接続端子部３６を接続した状態で携帯電話器Ｔのバッテリ１１を充電するために蓄電部７から定電力出力部１０へ流れる電流をＩ２ とすると、Ｉ１ ≫Ｉ２ となるように設定する。即ち、５≦Ｉ１ ／Ｉ２ ≦ ２００のように設定する。例えば、Ｉ１ ＝４０Ａ，Ｉ２ ＝ ０．５Ａのように設定すれば、Ｉ１ ／Ｉ２ ＝８０（倍）となり、Ｉ１ ＝ １００Ａ，Ｉ２ ＝ ０．５Ａのように設定すれば、Ｉ１ ／Ｉ２ ＝ ２００（倍）となる。大容量の蓄電部７によって、直列接続された電気二重層コンデンサ８…に充電するに要する時間ｔ１ は、約１０ｓｅｃ 〜約４０ｓｅｃ で行い得て、至便であり、コンビニエンスストアや公共場所等にて、次々と、持ち込まれる多数の携帯電話器２０に能率良く充電を完了してゆくことができ、充電が終われば、その満充電の携帯充放電器２０を携帯（持ち歩き）しつつ、携帯電話器２０に、十分な時間（一般に６０分〜９０分）を掛けて充電することが可能であるので便利である。言い換えれば、コンビニエンスストアや公共場所等に設置された共用充放電器１６の場所には、短時間拘束されるのみで、高速（１０ｓｅｃ 〜４０ｓｅｃ ）の充電の後は、直ちに携帯充放電器２０を携帯して持ち運び（移動）が可能であり、その間にも通話ができる。
【００２１】
次に、電源部１としては、例えば、図５又は図６若しくは図７に示す回路図が適用できる。
図５に於て、この電源部１は、商用電源１８から電力が供給される整流回路２２と、整流回路２２から電気エネルギが供給されるスイッチング部２３及び補助電源２４と、スイッチング部２３から出力トランス２５を介して電気エネルギが供給される高周波整流回路２６とを、備える。さらに、高周波整流回路２６から制御部２・蓄電池３（図４参照）へ供給される電気エネルギの電圧を検出して定電圧とするための定電圧制御部２７及びＰＷＭ制御部２８と、ＰＷＭ制御部２８からスイッチング部２３へ制御信号が送信される駆動トランス２９とを、備える。
【００２２】
また、図６に示す電源部１では、商用電源１８からの電力が供給される整流器３８と、平滑コンデンサ３９，４０と、チョークコイル４１をもって構成される。図７では、商用電源１８を、まず、降圧トランス４２へ供給し、その後に、整流器３８、及び、平滑コンデンサ３９，４０と、チョークコイル４１に送るように、構成される。
【００２３】
上述のような充放電装置（システム）を用いて、携帯電話器Ｔへ充電する方法について、以下、説明する。コンビニエンスストア、ホテル、駅、公共場所等にボックス型の共用充放電器１６を設置し、商用電源１８に接続し、蓄電池３を充電して、フロート充電として満充電状態で待機させておく。予め多数の（一揃えの）携帯充放電器２０…を多数の使用者に販売しておき、必要なとき、上記コンビニエンスストアや公共場所等に設置の共用充放電器１６の差込口（端子）５に、携帯充放電器２０の端子６を接続すると共に共用充放電器１６のコイン投入孔１２にコイン１３を投入する。センサ・スイッチ１４がそのコイン１３の投入を検知し、検出信号Ｉ１４によって定電力制御部４から、電流Ｉ１ のように、急速充電される。長くとも、１分〜２分にてその急速充電は完了する。好ましくは、１０ｓｅｃ 〜４０ｓｅｃ 、さらに望ましくは、１３ｓｅｃ 〜２０ｓｅｃ とする。充電管理表示部１５にてその充電の完了を知り得る。
【００２４】
その後、携帯充放電器２０を共用充放電器１６から分離する。この分離によって、直ちに携帯（移動）が可能となり、ハンドバッグやポケットやカバンに収納して移動し、その移動中に、携帯充放電器２０を携帯電話器Ｔに、接続して、充電させる。
【００２５】
携帯電話器Ｔのバッテリ１１は、リチウム・イオン又はニッカド電池が用いられて、電池の性質上、満充電に達するまでには、一般に、６０分〜９０分も掛かるが、人が移動中（外出中）に小型の携帯充放電器２０から容易に充電させ得る。このように、定置式の共用充放電器１６の設置場所に、携帯電話が、６０分〜９０分も拘束される不便は発生しないで済む。
【００２６】
【発明の効果】
本発明は上述の構成により次のような著大な効果を奏する。
【００２７】
（請求項１によれば、）１台の定置式共用充放電器１６に対して多数の携帯充放電器２０…を次々と短時間にて充電できる。従って、定置式共用充放電器１６の場所に拘束される時間が短時間で済み、携帯充放電器２０の充電の後は、直ちに、移動できて至便である。さらに、携帯充放電器２０のコンパクト化を図り易く、携帯電話器Ｔと共に充電した携帯充放電器２０を、カバンやハンドバッグやポケットに入れて持ち運べば、出先で必要な時、いつでも携帯電話器Ｔへ充電できる。また、定電圧出力部１０によって、携帯電話器Ｔ（のバッテリ１１を）定電圧を供給して充電するので、長い時間にわたって十分に充電させることができる。
【００２８】
（請求項２によれば、）共用充放電器１６は一般の人が利用に便利な場所に設置（固定）されているので、使い易く、また、コイン投入によって携帯充放電器２０への電気エネルギ供給が開始され、自動で使い易く、至便である。
（請求項３によれば、）定置式充放電器１６は重量大であっても定置式であるから問題がなく、従って、携帯充放電器２０側を十分に軽量化して、コンパクト化を図り得る。
【００２９】
（請求項４によれば、）直列接続の電気二重層コンデンサ８…は、携帯充放電器２０の軽量・コンパクト化を図る上で有効であり、かつ、携帯電話器Ｔのバッテリ１１を充電するに必要な電気エネルギを十分に蓄え得る。
（請求項５，６によれば、）人の自由が拘束されるところの定置式充放電器１６では十分急速な充電ができ、他方、人の自由が拘束されない（出先でのハンドバッグやポケット等内での充電が可能な）携帯電話器Ｔへの充電では、（リチウム・イオン又はニッカド電池等から成る）バッテリ１１に好適なゆっくりとした充電が行われ、合理的であり、使い勝手が著しく優れている。
【００３０】
（請求項７によれば、）急いで充電したいときには、コンビニエンスストア等で、一旦、携帯充放電器２０に急速充電し、その後、出先に於て、ゆっくりと時間を掛けて、携帯電話器Ｔのバッテリ１１を充電するので、従来の充電方法の不便を解決して、極めて便利である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a charge / discharge device for a mobile phone and a charging method.
[0002]
[Prior art]
Conventionally, charge / discharge devices such as the following portable telephone devices (1) to (5) have been known, and each has a problem. That is,
{Circle around (1)} As a charger for a mobile phone, a charger was connected to a commercial power supply, and a battery of the mobile phone was connected to the charger to charge the battery for a long time. For this reason, the mobile phone was restrained at the charger installation location.
(2) Some batteries are connected to a mobile phone through a controller to charge the battery, but when the battery is exhausted, it is necessary to replace it further, which has increased the cost.
(3) There is an example in which a spare portable battery is prepared, but it is expensive, and there is little demand for a spare battery for a portable telephone having a fast cycle.
(4) There is also known a device in which a plurality of cordless devices are charged by a common charger by using an electric double layer capacitor as a power source instead of a secondary battery (for example, see Patent Document 1). However, it is not suitable for carrying mobile phones.
(5) The charging DC power supply connected to the electric double layer capacitor of the cordless device and the charging capacitor connected in parallel between the DC power supply and the electric double layer capacitor are charged with the DC power supply and the charged charging is performed. A technique for charging an electric double layer capacitor with a capacitor is known (for example, refer to claim 1 of Patent Document 1). However, the electric energy stored in the charging capacitor is simply transferred to the electric double layer capacitor, which is not suitable for rapid battery charging of a portable telephone.
[0003]
[Patent Document 1]
Japanese Patent Publication No. Hei 8-31339
[Problems to be solved by the invention]
As described above, none of the conventional charging / discharging devices (1) to (5) has been known to be suitable for use in portable telephones. In particular, the conventional charger for a mobile phone (refer to the above (1)) converts a commercial power supply into a DC voltage suitable for a battery, connects the charger to the mobile phone, and charges the battery for a certain period of time. However, there is a major drawback in that the use of the mobile phone is limited until the battery is fully charged. In particular, there is no suitable charge / discharge system (apparatus / equipment) that can quickly and easily charge the mobile phone when the battery power of the mobile phone runs out while away from home, which is inconvenient. (In addition, a stationary charger / discharger that charges for 60 to 90 minutes is used in part.)
[0005]
Therefore, an object of the present invention is to install a stationary large-sized common charge / discharge device in a convenience store or the like, always store sufficient electric energy, and connect small portable charge / discharge devices one after another to each other. Charge the portable charger / discharger at high speed, then remove the portable charger / discharger from the shared charger / discharger, and charge the battery of the portable telephone with sufficient time while carrying the portable charger / discharger. It is to propose a new usage.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a charging / discharging device for a mobile phone according to the present invention includes: a stationary common charge / discharge device connected to a commercial power supply; and an electric energy supplied from the common charge / discharge device in a connected state. A plurality of portable charging / discharging units having a power storage unit composed of an electric double layer capacitor, a constant voltage output unit, and being connectable / separable to the common charging / discharging unit and being portable; The constant voltage output unit of the charger / discharger is configured to be connected to a battery of a mobile phone so as to be freely connected and charged.
The stationary common charge / discharge device is a box type installed in a convenience store, a hotel, a station, or a public place, has a coin insertion hole, and detects a coin inserted into the coin insertion hole. A switch, and an ON / OFF control means for controlling the supply of electric energy to the power storage unit of the portable charger / discharger in a connected state by a detection operation of the sensor switch.
[0007]
In addition, the stationary shared charger / discharger is a power supply unit for rectifying and stepping down AC power from a commercial power supply, a storage battery for storing DC power from the power supply unit, and a constant power for a connected portable charger / discharger. It has a constant power control unit for controlling the supply and a terminal to which the portable charger / discharger is connected and detachable.
The power storage unit of the portable charger / discharger is configured by connecting a plurality of electric double-layer capacitors for storing electric energy supplied from the shared charge / discharger in series.
Further, through the current flowing to the charging from the shared discharge unit to said power storage unit of the mobile charge and discharge device as well as the I 1, from the power storage unit to charge the battery of the mobile phone to the constant voltage output portion Assuming that the current is I 2 , the configuration is such that I 1 ≫I 2 . In particular, it is desirable to set 5 ≦ I 1 / I 2 ≦ 200.
[0008]
The method for charging a mobile phone according to the present invention includes installing a box-type shared charger / discharger at a convenience store, hotel, station, or public place, and using the portable charger / discharger having an electric double layer capacitor as the shared charge / discharger. While being connected to a discharger, a coin is inserted into the common charger / discharger for quick charging, and then the portable charger / discharger is separated from the common charger / discharger and carried, and the portable charger / discharger is carried during carrying. This is a method of connecting to a mobile phone and charging.
