【発明の属する技術分野】
本発明は、携帯電話用充放電器及びその使用方法に関する。
【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バッテリ充電には適さない。

【0004】
【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。
【0005】
そこで本発明の目的は、携帯電話器のバッテリ容量に見合う電気エネルギを商用電源又は自動車用バッテリから数分以内に充放電器に蓄え、その後、充放電器を商用電源又は自動車用バッテリから取り外し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に、本発明に係る携帯電話用充放電器は、電力入力部と、該電力入力部から電力が供給されるスイッチング電源部と、マイコン・ロジック回路を備え上記スイッチング電源部から電気エネルギを供給される制御部と、該制御部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有する蓄電部と、上記電気二重層コンデンサの充電状態を上記制御部に送信する帰還回路と、上記電気二重層コンデンサに蓄えられた電気エネルギを携帯電話のバッテリへ定電圧で供給するための出力部とを、備え、上記帰還回路によって送信される上記電気二重層コンデンサの上記充電状態に対応して上記電気二重層コンデンサの充放電及び供給電圧を上記制御部によって制御される。
【0007】
また、電力入力部が、商用電源及び自動車バッテリに択一的に接続可能とされている。
また、複数の電気二重層コンデンサが直列接続されている。
また、電気二重層コンデンサを充電する電流をI とすると共に、上記携帯電話のバッテリを充電するために、上記電気二重層コンデンサから出力部へ流れる電流をI とすると、I ≫I となるように、制御部にて制御する。
また、5≦I /I ≦50に設定される。
【0008】
また、複数の電気二重層コンデンサを直列接続し、該電気二重層コンデンサの各端子電圧を検出して帰還回路にて制御部へ送信し、該制御部のマイコン・ロジック回路のプログラム制御により、上記各端子電圧が使用耐圧範囲内になるように総電圧値を演算して、供給電圧として上記直列接続の複数の電気二重層コンデンサに供給する。
【0009】
また、複数の電気二重層コンデンサを直列接続し、該電気二重層コンデンサの各端子電圧を検出して帰還回路にて制御部ヘ送信しつつ、スイッチング電源部の電力能力最大限の電流を上記電気二重層コンデンサに供給するように、上記制御部のマイコン・ロジック回路のプログラム制御により、上記スイッチング電源部を制御する。
【0010】
また、本発明に掛かる携帯電話用充放電器の使用方法は、複数の電気二重層コンデンサを有する蓄電部と、電力入力部と、出力部とを備えた充放電器の上記電力入力部を、商用電源又は自動車バッテリに接続して上記蓄電部に急速充電し、その後、上記電力入力部を分離して上記充放電器を携帯し、携帯した上記充放電器の上記出力部を携帯電話のバッテリに接続して、上記急速充電の5倍〜50倍の時間を掛けて充電させる。
【0011】
【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。
【0012】
図1は、本発明の携帯電話用充放電器の実施の一形態を示す斜視図で、図2は、基本的な回路説明図である。この図1及び図2に於て、この充放電器30は、電力入力部12と、電力入力部12とコード29にて連結される充放電ケース15と、充放電ケース15とコード9にて連結される出力部6とを、備えている。電力入力部12としては、商用電源14用プラグ12Aを具備し、(所望により)自動車バッテリ13用プラグ12Bも具備する。好ましくは、電力入力部12が、商用電源14及び自動車バッテリ13に択一的に接続可能とする。
【0013】
この充放電ケース15内には、本発明の主要部が内蔵されている。即ち、電力入力部12から電力が供給されるスイッチング電源部1と、マイコン・ロジック回路25を備えスイッチング電源部1から電気エネルギを供給される制御部2と、制御部2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4を有する蓄電部3と、電気二重層コンデンサ4の充電状態を制御部2に送信する帰還回路5とを、備えている。そして、複数個の電気二重層コンデンサ4は直列に接続されている。電力入力部12は、商用電源14又は自動車用バッテリ13等の電源7に(接続分離自在に)接続され、出力部6は、携帯電話10のバッテリ8に(接続分離自在に)接続される。
【0014】
制御部2から電気二重層コンデンサ4へ流れる電流I は、電気二重層コンデンサ4から出力部6へ流れる電流I よりも極めて大きく、───つまり、I ≫I と───なるように、上記制御部2により制御される。例えば、5≦I /I ≦50に設定する。より望ましくは、10≦I /I ≦25に設定する。そして、帰還回路5によって送信される上記電気二重層コンデンサ4の充電状態に対応して、電気二重層コンデンサ4の充放電及び供給電圧を上記制御部2によって制御する。なお、出力部6は定電圧(DC−DC)コンバータを有し、バッテリ8へは定電圧で供給(出力)される。
【0015】
31は各電気二重層コンデンサ4の端子電圧V ,V ,V …を検出するために各電気二重層コンデンサ4に対して設けられた検出部であり、この検出部31にて検出した各電圧V ,V ,V …を、帰還回路5にて制御部2へ送信する。制御部2のマイコン・ロジック回路25のプログラム制御により、(各電気二重層コンデンサ4の静電容量・内部抵抗のばらつきが存在したとしても)各端子電圧V ,V ,V …が各々使用耐圧範囲内となるように総電圧値を演算して、供給電圧Eとして直列接続の複数の電気二重層コンデンサ4に供給する(図3参照)。26は、そのための(充電用)電流・電圧制御部である。
【0016】
そして、スイッチング電源部1は、商用電源14から電力が供給される整流回路16と、整流回路16から電気エネルギが供給されるスイッチング部17及び補助電源19と、スイッチング部17から出力トランス22を介して電気エネルギが供給される高周波整流回路18とを、備える。さらに、高周波整流回路18から制御部2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21及びPWM制御部20と、PWM制御部20からスイッチング部17へ制御信号が送信される駆動トランス23とを、備える。また、高周波整流回路18は、自動車用バッテリ13と接続されている。充放電ケース15は、例えば、縦辺L (10cm〜15cm),横辺L (8cm〜10cm),厚さL (0.5cm 〜3cm)を有する直方体形として、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。
【0017】
図3は、直列に接続された複数の電気二重層コンデンサ4…の回路図であり、電気二重層コンデンサ4…は、静電容量C ,C …,Cを有し、V ,V …,Vは、上述した夫々の端子電圧を示す。また、Eは、既述した蓄電部3の供給電圧であって、E=V +V +V +…+V(総電圧)に相当する。
【0018】
図4は、横軸に時間T(sec )を示し、縦軸に電気二重層コンデンサ4…へ流れる電流I (A)及び上記供給電圧E(V)を示したグラフ図である。t は定電流期間で、t は定電圧期間であり、Iは、蓄電部3に電流が流れ始めた際の突入電流の値を示す。
【0019】
充電電流I の変化と、電気二重層コンデンサ4…への供給(充電)電圧Eの変化について説明する。定電流期間t (例えば30秒〜 120秒)では、電流I は、充電開始の瞬間にはピークを示して突入電流Iとなり、その後、定電流(8A〜12A)となる。定電流期間t 中は、電圧Eは、緩やかに上昇して、前述したプログラム制御のために(予め)入力した総充電電圧値(供給電圧)Eが、E に達する。突入電流Iが流れるときの電圧Eは極めて低いので、この突入電流Iをコントロール(制御)する必要は(一般には)低い。
【0020】
しかしながら、供給電圧Eが所定値E に到達した後は、コントロール(制御)しないと、2点鎖線にて示すE 曲線のように急激に上昇して、各電気二重層コンデンサ4の耐圧をオーバーする危険性が生ずる。そこで、制御部2(電流・電圧制御部26等)によって、定電圧期間t に於ては、電流I を緩やかに減少させつつ、供給(充電)電圧Eを一定値E となるように制御する。この際、点線E にて示すように、不安定に電圧E が変動することも、制御部2によってコントロールする。定電圧期間t の最終時(例えば、スタートから 100秒〜 200秒後)には、1(A)等の低い値となる。上記E としては、例えば、4〜8(V)の値とする。
【0021】
次に、定電流期間t 中の上記定電流I について述べる。複数の電気二重層コンデンサ4の各端子電圧V ,V …,Vを検出して帰還回路5にて制御部2へ送信しつつ、スイッチング電源部1の電力能力最大限の電流I を供給するように、制御部2のマイコン・ロジック回路25のプログラム制御によって、スイッチング電源部1を制御する。言い換えると、直列接続の大容量の電気二重層コンデンサ4を急速充電する手段として、電気二重層コンデンサ4の端子電圧V ,V …,V及び充電電流I を検出し、供給電源部1の電力能力最大限の電流I 、及び、この電流I を供給すべき電圧E(E )を、マイコン・ロジック回路25のプログラムによって、制御して、図4に示す定電流期間t の制御を行う。
【0022】
なお、制御部2にソフトスタータを設けると、突入電流Iを制御し、充電初期の電流I を、電流Iのように略定電流以下に抑え、電気二重層コンデンサ4の耐圧を越えないように一層安全に充電を行うことも可能である。
【0023】
以上のように、本発明の携帯電話用充放電器30は、カバン,バッグ,ポケット等に入れられる大きさであり、電気二重層コンデンサ4に充電されて携行できるので、外出先で、消耗した携帯電話10のバッテリ8を接続して充電を行ったり、あるいは接続したまま携帯電話10を使用することも可能である。
【0024】
また、プラグ12Aとプラグ12Bを付設すれば、この充放電器30は、商用電源14だけでなく自動車バッテリ13を電源7にして充電が可能なので、充電場所が商用電源14の設置場所に限定されず、自動車での外出先においても充電が可能である。
【0025】
電気二重層コンデンサ4へ流れる電流I が、出力部6を介して携帯電話10のバッテリ8へ流れる電流I よりも極めて大きいので、充放電器30の充電を急速に(30秒〜2分にて)行うことができ、急いで出掛ける際の待ち時間が少なくなる。携帯電話10のバッテリ8へは、時間をかけて放電されるので、このコンパクトな充放電器30をポケットやカバン等に入れて携帯電話10と共に持ち歩く(携帯する)と、バッテリ8が充電を必要としたときにはコード9にて接続して直ちに、どこでも、充電が可能となり、さらに、携帯電話10を長時間(出先にて携帯電話10の使用中に充電しておけば)使用可能である。
【0026】
即ち、本発明に係る携帯電話用充放電器の使用方法によれば、複数の電気二重層コンデンサ4を有する蓄電部3と、電力入力部12と、出力部6とを備えた充放電器30の電力入力部12を、商用電源14又は自動車バッテリ13に接続して蓄電部3に急速充電し、その後、電力入力部12を分離して充放電器30を携帯し、携帯した充放電器30の出力部6を携帯電話10のバッテリ8に接続して、急速充電の5倍〜50倍の時間を掛けて充電させる方法であり、家庭や自動車内で急速充電の後に、じっくりと携帯電話10のバッテリ8を充電させ得るものである。
【0027】
また、直列に接続する複数の電気二重層コンデンサ4…の夫々の端子電圧V ,V …,Vを検出部31にて検出して、トータルの総電圧Eを予めプログラム入力した電圧(使用耐圧)E 内に制御したので、電気二重層コンデンサ4…を損傷させることなく、充放電器30を有効に使用することができる。
【0028】

(請求項1によれば、)電気二重層コンデンサ4が損傷を受けない限度内で急速充電することができて至便である。従って、充放電器を充電中に拘束される時間が短くなる。さらに、コンパクト化も図りやすく、携帯電話10と共に、充電後の充放電器を、バッグやポケットに入れて持ち運べば、出先で必要な時にいつでも携帯電話10へ充電することができて、一層便利である。また、出力部6はバッテリ8へ定電圧で供給するため、長い時間にわたって十分に充電することができる。
【0029】

【0032】
(請求項6によれば、)制御回路が簡素化できて、安価提供ができ、しかも、各電気二重層コンデンサ4の耐久性も十分に長くすることが可能となり、実用性が極めて高い。

[0018]
FIG. 4 is a graph showing the time T (sec) on the horizontal axis and the current I 1 (A) flowing to the electric double layer capacitors 4 and the supply voltage E (V) on the vertical axis. t 1 is a constant current period, t 2 is the constant voltage period, I p denotes a value of a rush current when a current starts to flow in the power storage unit 3.
[0019]

However, after the supply voltage E reaches the predetermined value E 0 , if the control is not performed (control), the voltage rapidly rises as indicated by the E 2 curve shown by the two-dot chain line, and the withstand voltage of each electric double layer capacitor 4 is reduced. There is a risk of overrun. Therefore, the control unit 2 (current-voltage control unit 26, etc.), Te is at a constant voltage period t 2, while reducing the current I 1 gradually, supplied (charged) to the voltage E becomes a constant value E 0 To control. At this time, as shown by the dotted line E 3, unstable even when a voltage E 3 fluctuates, controlled by the control unit 2.
