Description

本発明は、携帯電話機を充電する充電器及び充電方法に関する。   The present invention relates to a charger and a charging method for charging a mobile phone.

わが国における携帯電話機の販売台数は９千万台を超え、現代生活の必需品となった。その機能は年々付加されて多機能化の一途をたどっており、メールの送受信、音楽プレイヤ、ゲームプレイヤ、テレビ放送の視聴、おサイフ携帯、動画ビデオ撮影など、とどまるところを知らない。   The number of mobile phones sold in Japan exceeded 90 million units, making it a necessity for modern life. The functions are added year by year and are becoming more and more multifunctional, and there is no end to them such as mail transmission / reception, music player, game player, watching TV broadcast, wallet mobile phone, video shooting.

ところで、携帯電話機は、内蔵される二次電池で駆動している。そして、その使用可能時間をできるだけ長くとるため、エネルギ密度の高いリチウム電池が使われている。電話がかかってくるのを待つだけの待受け時間であれば、３００時間程度とれる。しかし、連続通話時間は２時間程度である。また、ゲームを楽しんだり、テレビ放送の視聴、メール作成、メール送受信に使用すると、その分だけ、通話可能時間は短くなる。   By the way, the mobile phone is driven by a built-in secondary battery. In order to make the usable time as long as possible, a lithium battery with high energy density is used. If the standby time is just waiting for a phone call, it can take about 300 hours. However, the continuous call time is about 2 hours. Also, if you use it for enjoying games, watching TV broadcasts, creating e-mails, and sending / receiving e-mails, the available call time will be reduced accordingly.

したがって、外出中に想定外の場所で電池の容量が低下し、通話ができなくなることがある。そうした場合には、充電器を所持していないことが多く、しばらくは連絡がとれなくなり、仕事に支障をきたす。また、充電器（交流電源を得て直流電力に変換するもの）を所持していた場合でも、電源コンセントからの電力供給を思うように得られずに、充電できない場合もある。そうなるとせっかく携帯電話機を持ち歩いても、その便利さが損なわれてしまう。   Therefore, the capacity of the battery may be reduced at an unexpected place while going out, making it impossible to make a call. In such cases, you often don't have a charger, and you won't be able to get in touch for a while, which hinders your work. Even when a charger (which obtains an AC power supply and converts it to DC power) is possessed, there is a case where the power supply from the power outlet cannot be obtained as desired and charging cannot be performed. Then, even if you carry your mobile phone with you, the convenience will be lost.

そうした事態に対処するため、一次電池（直流の電力の放電のみができる化学電池、使い捨て電池）と充電用回路とを組み合わせた携帯電話用緊急充電器がコンビニエンスストアや家電量販店で販売されてきた。   To deal with such a situation, emergency chargers for mobile phones that combine primary batteries (chemical batteries that can only discharge DC power, disposable batteries) and charging circuits have been sold at convenience stores and consumer electronics mass retailers. .

特許文献１には、過充電、過放電、放電過電流、または充電過電流を検出して、二次電池を保護することができる充放電保護回路及び該充放電保護回路を組み込んだバッテリーパックが開示されている。それぞれの検出回路を設けて、放電制御用ＦＥＴ（フィールドイフェクトトランジスタ、電界効果トランジスタ)、充電制御用ＦＥＴのオンオフを制御するようにしたものである。   Patent Document 1 discloses a charge / discharge protection circuit capable of protecting a secondary battery by detecting overcharge, overdischarge, discharge overcurrent, or charge overcurrent, and a battery pack incorporating the charge / discharge protection circuit. It is disclosed. Each detection circuit is provided to control on / off of the discharge control FET (field effect transistor, field effect transistor) and charge control FET.

特許文献２には、充電回路を内蔵しない安価な電池パックを充電対象としながらも、電気機器に装着された電池パックと、該電気機器に装着されない予備電池パックとの同時充電が可能な充電器が開示されている。携帯電話機に装着された電池パックを充電するための第一給電端子と、予備電池パック単体を充電するための第二給電端子と、予備電池パックの充電制御を行う充電回路とを有してなり、該充電回路への入力電圧の大きさに基づいて、予備電池パックの充電動作をオン／オフ制御するものである。
特開２００２−１７６７３０号公報 特開２００３−１６４０７０号公報 Patent Document 2 discloses a charger capable of simultaneously charging a battery pack attached to an electric device and a spare battery pack not attached to the electric device while charging an inexpensive battery pack not including a charging circuit. Is disclosed. A first power supply terminal for charging the battery pack mounted on the mobile phone; a second power supply terminal for charging the spare battery pack alone; and a charging circuit for controlling charging of the spare battery pack. The on / off control of the charging operation of the spare battery pack is performed based on the magnitude of the input voltage to the charging circuit.

上述した一次電池と充電用回路とを組み合わせた携帯電話用充電器は、一次電池を用いているために大きく、かつ、重い。充電用回路の部分は再利用ができるにもかかわらず、一次電池が使い捨てであることから、充電用回路もまた電池と共に捨てられる可能性があり、地球環境に対して好ましくない。   The mobile phone charger that combines the above-described primary battery and charging circuit is large and heavy because the primary battery is used. Although the portion of the charging circuit can be reused, the primary battery is disposable, so that the charging circuit may also be discarded together with the battery, which is undesirable for the global environment.

特許文献１に開示される保護回路は、二次電池がなんらかの原因で膨張してしまうこと自体を検出することはできない。   The protection circuit disclosed in Patent Document 1 cannot detect that the secondary battery expands for some reason.

特許文献２に開示する充電器は、一度の充電操作により、携帯電話機内部の二次電池と、予備電池とを双方とも充電することを可能にするものである。しかし、携帯電話機内部の容量不足となったときに、携帯電話機の裏蓋をあけて、電池交換をする必要がある。日常的に行う動作としては手間のかかる動作である。また、頻繁に電池交換をすることにより、裏蓋の開け閉めの頻度が増え、それにより、裏蓋のロックがあまくなり、落下による紛失などの事故にもつながる。   The charger disclosed in Patent Document 2 makes it possible to charge both the secondary battery and the spare battery inside the mobile phone by a single charging operation. However, when the capacity of the mobile phone becomes insufficient, it is necessary to open the back cover of the mobile phone and replace the battery. The daily operation is a time-consuming operation. In addition, frequent replacement of the battery increases the frequency of opening and closing the back cover, which increases the lock of the back cover and leads to accidents such as loss due to falling.

以下、図面を参照しつつ、本発明を実施するための最良の形態を説明する。   Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

図１は、本発明に係る充電器２０を携帯電話機１０とそのＡＣアダプタ３０との中間に位置せしめた状態を示す模式図である。ＡＣアダプタ３０は、携帯電話機１０の購入時に付属するＡＣアダプタであり、家庭用の交流電源から電力を得て、それを直流に変換して、携帯電話機１０の内部にある電話機内二次電池１１（図示は省略）を充電する。このとき、電話機内二次電池１１の内部には、特に過放電・過充電などから電話機内二次電池１１を保護する保護回路は設けられていない。携帯電話機１０の内部に、充電電流を制御する回路、過放電・過充電から保護する保護回路が設けられている。   FIG. 1 is a schematic view showing a state in which a charger 20 according to the present invention is positioned between a mobile phone 10 and an AC adapter 30 thereof. The AC adapter 30 is an AC adapter that is attached when the mobile phone 10 is purchased. The AC adapter 30 obtains power from a home AC power source, converts it into direct current, and the secondary battery 11 in the phone inside the mobile phone 10. (Not shown) is charged. At this time, a protection circuit for protecting the in-phone secondary battery 11 from overdischarge / overcharge is not provided inside the in-phone secondary battery 11. Inside the mobile phone 10, a circuit for controlling the charging current and a protection circuit for protecting from overdischarge / overcharge are provided.

日本国内の携帯電話機にあっては、携帯電話機１０とＡＣアダプタ３０との間を接続するコネクタは、１０ピン又は１８ピンのものが採用されている。以下、本明細書にあっては、携帯電話機側のＡＣアダプタに接続するための端子を対ＡＣアダプタ電力端子１４と呼び、ＡＣアダプタ側の携帯電話機に接続するための端子を対電話機電力端子３２と呼ぶ。本発明に係る充電器の携帯電話機に接続する側には、対電話機電力端子２２を設けてあり、ＡＣアダプタに接続する側には、対ＡＣアダプタ電力端子２４が設けてある。これにより、携帯電話機１０、充電器２０、ＡＣアダプタ３０とは、図１に示すように、直列に接続され得る。   In a mobile phone in Japan, a connector that connects the mobile phone 10 and the AC adapter 30 has a 10-pin or 18-pin connector. Hereinafter, in this specification, a terminal for connecting to the AC adapter on the mobile phone side is referred to as an AC adapter power terminal 14, and a terminal for connecting to the mobile phone on the AC adapter side is an anti-phone power terminal 32. Call it. The telephone power terminal 22 is provided on the side connected to the mobile phone of the charger according to the present invention, and the power terminal 24 for AC adapter is provided on the side connected to the AC adapter. Thereby, the mobile phone 10, the charger 20, and the AC adapter 30 can be connected in series as shown in FIG.

図１に示すような、三つの機器を直列に接続して使う場合だけではなく、本発明に係る充電器２０を携帯電話機１０にだけ接続して、充電器内二次電池２１により電話機内二次電池１１を充電することもできる。また、本発明に係る充電器２０をＡＣアダプタ３０にだけ接続して交流電源を用いて充電器内二次電池２１（後述する図５、図６では、ＢＡＴＴ＋、ＢＡＴＴ−に接続される二次電池）を充電することもできる。   As shown in FIG. 1, not only when three devices are connected in series, but the charger 20 according to the present invention is connected only to the mobile phone 10 and the secondary battery 21 in the charger can The secondary battery 11 can also be charged. Further, the charger 20 according to the present invention is connected only to the AC adapter 30 and an AC power supply is used to connect the secondary battery 21 in the charger (secondary connected to BATT + and BATT− in FIGS. 5 and 6 described later). Battery) can also be charged.

図２は、本発明に係る充電器のブロック図である。充電器内二次電池２１から放電される電流は昇圧部２３により昇圧されて対電話機電力端子２２を介して電話機１０に供給され、電話機内二次電池１１を充電する。昇圧部２３は、後述する図５、図６の回路でいうと制御素子Ｑ７，Ｑ８，Ｑ１１、コイルＬ１、コンデンサＣ４，Ｃ５、抵抗Ｒ１１，Ｒ１２、ダイオードＤ３，集積回路Ｕ２により構成される部分である。   FIG. 2 is a block diagram of a charger according to the present invention. The current discharged from the in-charger secondary battery 21 is boosted by the booster 23 and supplied to the telephone 10 via the telephone power terminal 22 to charge the in-phone secondary battery 11. In the circuits of FIGS. 5 and 6 to be described later, the boosting unit 23 is a portion constituted by control elements Q7, Q8, Q11, a coil L1, capacitors C4, C5, resistors R11, R12, a diode D3, and an integrated circuit U2. is there.

ＡＣアダプタ３０から対ＡＣアダプタ電力端子２４を介して供給される充電電流は、温度上昇検知保護回路２７、充電器内二次電池充電電流制御回路２６を介して充電器内二次電池２１に至り、それを充電する。また、充電器内二次電池２１の充電に関しては、容器膨張検知保護回路２８及び制御部２９も関与して、必要な場合には、その充電動作を停止する。ここで、温度上昇検知保護回路２７は、ポリスイッチと呼ばれるものであり、温度の上昇により抵抗値が極めて大きくなり、それにより電流の流れを止めるものである。
また、容器膨張検知保護回路２８は、ここでは押しボタンスイッチを採用しており、充電器内二次電池２１が膨張することを機械的に検知し、その情報を制御部２９に伝達することにより、充電動作を停止する。過充電・過放電を回路により検出した場合も、充電動作を停止する。充電器内二次電池充電電流制御回路２６は、後述する図５、図６の回路にある制御素子Ｑ１及びダイオードＤ２を含む回路である。制御部２９は、後述する図５、図６の回路にある集積回路Ｕ１により構成される回路である。 The charging current supplied from the AC adapter 30 to the AC adapter power terminal 24 reaches the secondary battery 21 in the charger via the temperature rise detection protection circuit 27 and the secondary battery charging current control circuit 26 in the charger. Charge it. Further, regarding the charging of the secondary battery 21 in the charger, the container expansion detection protection circuit 28 and the control unit 29 are also involved, and when necessary, the charging operation is stopped. Here, the temperature rise detection protection circuit 27 is called a polyswitch, and the resistance value becomes extremely large due to the temperature rise, thereby stopping the current flow.
The container expansion detection protection circuit 28 employs a push button switch here, mechanically detects that the secondary battery 21 in the charger is expanded, and transmits the information to the control unit 29. Stop charging operation. The charging operation is also stopped when overcharge / overdischarge is detected by the circuit. The in-charger secondary battery charging current control circuit 26 is a circuit including a control element Q1 and a diode D2 in the circuits of FIGS. The control unit 29 is a circuit configured by an integrated circuit U1 in the circuits of FIGS.

ＡＣアダプタ３０と携帯電話機１０との双方をこの充電器２０に接続している場合の動作は複雑である。おおまかにいうと、はじめに、ＡＣアダプタ３０からの充電電流をまずは通過させて、携帯電話機１０にそのまま引渡し、電話機内二次電池１１を充電する。電話機内二次電池１１の満充電を検知したら、充電器内二次電池の充電動作に入る、という処理である。詳しくは、図５又は図６の詳しい回路図を参照しつつ、後述する。   The operation when both the AC adapter 30 and the mobile phone 10 are connected to the charger 20 is complicated. Roughly speaking, first, a charging current from the AC adapter 30 is first passed, and then delivered to the mobile phone 10 as it is, and the secondary battery 11 in the phone is charged. When the full charge of the secondary battery 11 in the telephone is detected, the charging operation of the secondary battery in the charger is started. Details will be described later with reference to the detailed circuit diagram of FIG.

図３は、本発明に係る充電器の内部構造を示す断面模式図である。充電器内二次電池２１は、本来直方体に近い形状と考えられるが、なんらかの原因によりその容器が膨張する場合には、中央部が膨らんで楕円体に近づくと考えて図３においては楕円形状でその断面を示してある。充電器内二次電池２１が万一膨張した場合に、それを検知できるように、機械的な押しボタンスイッチを容器膨張検知保護回路２８として回路基板４０上に設ける。支柱４１は、充電器内二次電池２１を支えるものである。   FIG. 3 is a schematic cross-sectional view showing the internal structure of the charger according to the present invention. The secondary battery 21 in the charger is considered to have a shape that is essentially a rectangular parallelepiped, but when the container expands for some reason, it is assumed that the central portion swells and approaches an ellipsoid. The cross section is shown. A mechanical push button switch is provided on the circuit board 40 as a container expansion detection protection circuit 28 so that it can be detected if the secondary battery 21 in the charger is expanded. The support column 41 supports the secondary battery 21 in the charger.

図４は、本発明に係る充電器の外観を示す斜視図である。本発明に係る充電器には、充電完了時や保護回路動作時には、状態に応じた色で点灯するＬＥＤ及び、本発明の本体に備えているボタンＳＷ２を押すことで白色ＬＥＤが点灯し、簡単な照明として利用することもできる機能も付属している。図４の白色ＬＥＤ点灯スイッチ４２は、充電器２０の外側に設けられて、使用者が暗いところで明かりが欲しい際に押すと、白色ＬＥＤ４３が点灯するものである。対電話機電力端子２２及び対ＡＣアダプタ電力端子２４は、携帯電話機１０及びＡＣアダプタ３０と接続する際にバランスのよい位置に設けられる。   FIG. 4 is a perspective view showing the external appearance of the charger according to the present invention. In the charger according to the present invention, when the charging is completed or when the protection circuit is operated, the white LED is lit by pressing the button SW2 provided in the main body of the present invention and the LED that lights up in a color corresponding to the state. It also comes with a function that can be used as a simple lighting.

携帯電話機１０に付属しているＡＣアダプタ３０を本発明に係る充電器２０の対ＡＣアダプタ電力端子２４に接続することで充電器内二次電池２１への充電動作が開始される。ＡＣアダプタ３０から供給された電源は、本発明に係る充電器２０の充電器内二次電池充電電流制御回路２６内の制御素子Ｑ１及びダイオードＤ２を通じて充電器内二次電池２１に供給されそれを充電する。 [Charging operation for the secondary battery in the charger of the charger according to the present invention (cell phone is not connected)]
By connecting the AC adapter 30 attached to the mobile phone 10 to the AC adapter power terminal 24 of the charger 20 according to the present invention, the charging operation to the secondary battery 21 in the charger is started. The power supplied from the AC adapter 30 is supplied to the in-charger secondary battery 21 through the control element Q1 and the diode D2 in the in-charger secondary battery charging current control circuit 26 of the charger 20 according to the present invention. Charge.

制御部Ｕ１は、ＶＤＤ−ＶＳＳ間の電圧を監視し充電器内二次電池２１に対する充電電圧、放電電圧を監視し、充電制御用端子ＣＯに接続される制御素子Ｑ９及び放電制御用端子ＤＯに接続される制御素子Ｑ１０をコントロールし、過充電、過放電にならないよう制御する。通常状態では、Ｑ９ Ｑ１０ともに導通状態となっている。過充電または過放電の状況によりそれぞれの制御素子がオフ状態となり回路が遮断される。
さらに電流制御用端子ＶＭに接続された抵抗Ｒ９に発生する電圧を元に充電電流を制御し過電流であることを検出すると放電制御素子Ｑ１０をオフにすることで過電流にならないよう制御する。 The control unit U1 monitors the voltage between VDD and VSS, monitors the charging voltage and discharging voltage for the secondary battery 21 in the charger, and supplies the control element Q9 connected to the charging control terminal CO and the discharging control terminal DO. The connected control element Q10 is controlled to prevent overcharging and overdischarging. In the normal state, both Q9 and Q10 are in a conducting state. Depending on the overcharge or overdischarge situation, the respective control elements are turned off and the circuit is shut off.
Further, the charging current is controlled based on the voltage generated at the resistor R9 connected to the current control terminal VM, and when it is detected that the overcurrent is detected, the discharge control element Q10 is turned off to control the overcurrent.

また、保護装置として電源部には温度で電気抵抗が大きく増加する保護スイッチＰＬ１（図２における温度上昇検知保護回路２７）が設けられ、充電器内二次電池や回路の異常等で本発明の充電器の筐体内部温度が上昇した場合、充電器内二次電池が回路から切断される構成となっている。
温度が低下すると保護スイッチＰＬ１の電気抵抗が小さくなり、自動的に通電される。 Further, as a protection device, a protection switch PL1 (temperature rise detection protection circuit 27 in FIG. 2) whose electric resistance greatly increases with temperature is provided in the power supply unit, and the battery of the present invention is detected due to abnormality of the secondary battery in the charger or the circuit. When the internal temperature of the charger casing increases, the secondary battery in the charger is disconnected from the circuit.
When the temperature decreases, the electrical resistance of the protective switch PL1 decreases, and power is automatically supplied.

また、押しボタンスイッチで構成される保護スイッチＳＷ１（図２における容器膨張保護回路２８）が回路基板４０と充電器内二次電池２１とに挟まれるように設置されている。万が一、何らかの理由で充電器内二次電池２１が異常状態となって容器が膨張した場合、保護スイッチＳＷ１が充電器内二次電池の膨張を物理的に検知し（体積膨張により二次電池の容器の外側が機械的に押しボタンを押すことを検知し）、充電器内二次電池２１への電源供給を止め、電池の爆発等を事前に保護する。   Further, a protection switch SW1 (a container expansion protection circuit 28 in FIG. 2) configured by a push button switch is installed so as to be sandwiched between the circuit board 40 and the secondary battery 21 in the charger. If for any reason the secondary battery 21 in the charger becomes abnormal and the container expands, the protection switch SW1 physically detects the expansion of the secondary battery in the charger (the secondary battery is It is detected that the outside of the container pushes the push button mechanically), the power supply to the secondary battery 21 in the charger is stopped, and the battery explosion is protected in advance.

［本発明に係る充電器から携帯電話機の電話機内二次電池への充電動作］
外出先等でＡＣアダプタ３０が使えない場合、携帯電話機１０を充電するには本発明に係る充電器２０と携帯電話機１０とを接続する。
充電器内二次電池２１から昇圧部２３のコイルＬ１へ電源が供給され、携帯電話機１０に内蔵されている電話機内二次電池１１を充電するに適した電圧まで昇圧し、充電を行う。 [Charging operation from the charger according to the present invention to the secondary battery in the mobile phone]
When the AC adapter 30 cannot be used when away from home, the charger 20 according to the present invention and the mobile phone 10 are connected to charge the mobile phone 10.
Power is supplied from the in-charger secondary battery 21 to the coil L1 of the booster 23, and the voltage is increased to a voltage suitable for charging the in-phone secondary battery 11 built in the mobile phone 10 to perform charging.

本発明に係る充電器２０をその対電話機電力端子２２と携帯電話機１０側の対ＡＣアダプタ電力端子１４とをつなぐことにより携帯電話機１０に接続すると、携帯電話機１０の所定のピン（１０ピンコネクタの場合は図５の右側コネクタの５ピン、１８ピンコネクタの場合は図６右側コネクタの１６ピン）をプラス側とし、そこから携帯電話機１０自体に内蔵されている充電回路に電源が供給され、マイナス側となる１ピンとの間に電流が流れる。
このとき、抵抗Ｒ１１、制御素子Ｑ１１を介して抵抗Ｒ１２に電流が供給されるため抵抗Ｒ１２で発生した電圧で昇圧部２３の集積回路Ｕ１のＯＮ−ＯＦＦ端子がＯＮに設定され昇圧部２３が動作を開始する。
昇圧部２３には、専用の電圧、電流の制御回路が設けられており、これにより安全に携帯電話機１０への充電を行うことができる。昇圧部の役割は充電器内二次電池２１の放電に伴う電圧低下を補償し、携帯電話機に安定した電圧を供給することである。 When the charger 20 according to the present invention is connected to the mobile phone 10 by connecting the power terminal 22 to the mobile phone 10 and the AC adapter power terminal 14 on the mobile phone 10 side, a predetermined pin (of the 10-pin connector) of the mobile phone 10 is connected. 5 in the right connector in FIG. 5 and 16 pins in the right connector in FIG. 6 in the case of the 18-pin connector), the power is supplied to the charging circuit built in the mobile phone 10 itself, and the minus Current flows between the pin 1 on the side.
At this time, since the current is supplied to the resistor R12 via the resistor R11 and the control element Q11, the ON-OFF terminal of the integrated circuit U1 of the booster 23 is set ON by the voltage generated at the resistor R12, and the booster 23 operates. To start.
The booster unit 23 is provided with a dedicated voltage / current control circuit, whereby the mobile phone 10 can be charged safely. The role of the booster is to compensate for the voltage drop accompanying the discharge of the secondary battery 21 in the charger and to supply a stable voltage to the mobile phone.

［携帯電話機と本発明に係る充電器とＡＣアダプタとを直列に接続した場合］
この場合、携帯電話機１０に対する充電は、ＡＣアダプタ３０から本発明に係る充電器２０を通過して直接行われる。
具体的には対ＡＣアダプタ電力端子２４の所定のピン（１０ピンコネクタの場合は図５の左側コネクタの５ピン、１８ピンコネクタの場合は図６左側コネクタの１６ピン）より供給された電源は、ダイオードＤ１を通じ対電話機電力端子２２の対応するピン（１０ピンコネクタの場合は図５右側のコネクタの５ピン、１８ピンコネクタの場合は図６右側のコネクタの１６ピン）を介して携帯電話機１０へ供給される。 [When a mobile phone, a charger according to the present invention, and an AC adapter are connected in series]
In this case, the mobile phone 10 is charged directly from the AC adapter 30 through the charger 20 according to the present invention.
Specifically, the power supplied from a predetermined pin of the AC adapter power terminal 24 (in the case of a 10-pin connector, 5 pins of the left connector in FIG. 5 and in the case of an 18-pin connector, 16 pins of the left connector in FIG. 6) Through the diode D1, the mobile phone 10 is connected via the corresponding pin of the telephone power terminal 22 (in the case of a 10-pin connector, the pin 5 on the right side of FIG. 5 and in the case of an 18-pin connector, the 16 pin on the right side of FIG. 6). Supplied to.

このとき、携帯電話用充電器を介して供給される電圧を制御素子Ｑ７が検知し、昇圧部のＯＮ−ＯＦＦ端子を制御し昇圧部の動作を停止させる。また、携帯電話機の電話機内二次電池１１が充電されている間、ダイオードＤ４がマイナス側につながるため制御素子Ｑ１がオフとなり本発明に係る充電器２０の充電器内二次電池２１に対する充電用電源供給も停止する。   At this time, the control element Q7 detects the voltage supplied via the mobile phone charger, and controls the ON-OFF terminal of the booster to stop the operation of the booster. Further, while the secondary battery 11 in the telephone of the mobile phone is being charged, the control element Q1 is turned off because the diode D4 is connected to the negative side, and the secondary battery 21 in the charger of the charger 20 according to the present invention is charged. Power supply is also stopped.

携帯電話機１０の電話機内二次電池１１に対する充電は携帯電話機１０に内蔵されている充電回路により行われる。電話機内二次電池１１が満充電になると携帯電話に内蔵されている充電回路が遮断される。
その結果、図５右側のコネクタ５ピンと１ピントの間（図６右側のコネクタ１６ピンと１ピンとの間）の電流が停止し、ダイオードＤ４がマイナス側から遮断され制御素子Ｑ１がオンとなり、本発明の充電器２０の充電器内二次電池２１に対する充電ができる状態となる。 Charging of the in-phone secondary battery 11 of the mobile phone 10 is performed by a charging circuit built in the mobile phone 10. When the in-phone secondary battery 11 is fully charged, the charging circuit built in the mobile phone is cut off.
As a result, the current between the connector 5 pin and 1 pin on the right side of FIG. 5 (between the connector pin 16 and 1 pin on the right side of FIG. 6) stops, the diode D4 is cut off from the minus side, and the control element Q1 is turned on. It becomes the state which can charge with respect to the secondary battery 21 in the charger of the charger 20 of.

制御部２９（集積回路Ｕ１を含む回路）により本発明の充電器２０の充電器内二次電池２１への充電が必要に応じ開始される。
充電器内二次電池２１も満充電となると制御部２９の充電制御素子Ｑ９をオフさせ充電動作が停止される。 The controller 29 (a circuit including the integrated circuit U1) starts charging the secondary battery 21 in the charger of the charger 20 of the present invention as necessary.
When the secondary battery 21 in the charger is also fully charged, the charging control element Q9 of the control unit 29 is turned off and the charging operation is stopped.

仮に何らの制御も行われないと、電話機内二次電池１１が充電される時でも、充電器内二次電池２１に対する充電も同時に開始され、電話機内二次電池１１と充電器内二次電池２１との２個の二次電池それぞれの使用状態により、充電動作が異なりどちらに優先充電されるか不定となる可能性がある。また、電流も制限一杯まで流れる場合がある。
そこでＡＣアダプタ３０の許容電流を考慮し、本発明に係る充電器２０の充電器内二次電池２１に対する充電電流は、前記の動作のとおり携帯電話に内蔵されている２次電池が優先されている場合、前述のように制御素子Ｑ１をオフするとともにＱ１と並列に接続されている抵抗Ｒ６を通じ通常の電流値より微小な電流値（１０ｍＡ程度）に制御し充電させることでＡＣアダプタ３０に対し過負荷となることを防いでいる。 If no control is performed, even when the in-phone secondary battery 11 is charged, charging of the in-charger secondary battery 21 is started at the same time, and the in-phone secondary battery 11 and the in-charger secondary battery are also started. Depending on the usage state of the two secondary batteries 21, there is a possibility that the charging operation is different and which is preferentially charged becomes undefined. Also, the current may flow up to the limit.
Therefore, in consideration of the allowable current of the AC adapter 30, the charging current for the secondary battery 21 in the charger 20 according to the present invention is given priority to the secondary battery built in the mobile phone as described above. If the control element Q1 is turned off as described above, the AC adapter 30 is charged by controlling and charging the current value to be smaller than the normal current value (about 10 mA) through the resistor R6 connected in parallel with Q1. This prevents overloading.

携帯電話機と同様に内部に二次電池を内蔵しており、ＡＣアダプタを接続することで内部の二次電池を充電することとしている電子機器一般に対して応用することができる。   Similar to a mobile phone, a secondary battery is built in, and the present invention can be applied to general electronic devices that charge an internal secondary battery by connecting an AC adapter.
