Abstract
Description
本発明は、二次電池、二次電池パックおよびそれを電源として用いた電子機器に関する。 The present invention relates to a secondary battery, a secondary battery pack, and an electronic device using the same as a power source.
従来、二次電池単体の個別認識情報を認識することがなかったが、二次電池パックにおいては、認識する技術が広く知られている。二次電池パックの識別の目的は、正規に設計された充電器との組合せにより、大きくは、二次電池の識別、および電池品種の識別に二分される。ここで二次電池の識別に関しては、使用する電子機器の二次電池収納部に合わせた形状・寸法により、一方、二次電池品種の識別に関しては、二次電池パックの充電端子の＋側を固定位置とし、−側の位置を品種によって個別に対応する方法により行われていた。 Conventionally, individual recognition information of a single secondary battery has not been recognized. However, a technology for recognizing a secondary battery pack is widely known. The purpose of the identification of the secondary battery pack is roughly divided into the identification of the secondary battery and the identification of the battery type by the combination with a properly designed charger. Here, regarding the identification of the secondary battery, depending on the shape and size according to the secondary battery housing portion of the electronic device to be used, on the other hand, regarding the identification of the secondary battery type, the positive side of the charging terminal of the secondary battery pack is The fixed position is used, and the position on the-side is individually handled according to the product type.
しかし、このような二次電池パックの充電端子に、正規に設計された充電器以外の充電器を直接接続した場合でも、充電可能でありながらも充電時における電池の安全性は保証されないという課題を有していた。 However, even when a charger other than a properly designed charger is directly connected to the charging terminal of such a secondary battery pack, it is possible to charge the battery, but the safety of the battery during charging is not guaranteed. Had.
そこで、二次電池パックに識別回路を設けることで、二次電池パック側で充電器の識別を行い、専用充電器以外は充電回路を形成できない状態とし、専用充電器からの充電制御信号を二次電池パックが認識してはじめて、充電回路のスイッチが閉じ充電回路を形成する方法が開示されている。（例えば、特許文献１参照）
さらに、電源部、受信部および送信部を内蔵した真贋判定回路を備えた二次電池パックであり、二次電池パックが電子機器に装着されて起動電波を受信すると、真贋判定回路の電源部が受信部と送信部に電力を供給し、送信部が真贋判定電波を送信することにより、二次電池パックの真贋判定を行う方法が開示されている。（例えば、特許文献２参照）
Furthermore, the secondary battery pack includes an authenticity determination circuit including a power supply unit, a reception unit, and a transmission unit. When the secondary battery pack is attached to an electronic device and receives a startup radio wave, the power supply unit of the authenticity determination circuit is A method is disclosed in which power is supplied to a receiving unit and a transmitting unit, and the transmitting unit transmits an authenticity determination radio wave, thereby performing authenticity determination of the secondary battery pack. (For example, see Patent Document 2)
しかしながら、上述した特許文献１の従来技術は、二次電池パックの充電端子に正規に設計された充電器以外の充電器を直接接続した際、あるいは二次電池パックを装着した電子機器の充電端子に正規に設計された充電器以外の充電器を直接接続した際は、充電器側の充電端子の配置が同一の場合には専用充電器以外でも充電可能であり、充電時における電池の安全性は保証されないという課題を有していた。また、このような課題は、二次電池の識別が二次電池パック本体ではなく、充電器側で識別を行うことが主流となっていることにも起因している。 However, the above-described prior art disclosed in Patent Document 1 is such that when a charger other than a normally designed charger is directly connected to the charging terminal of the secondary battery pack, or the charging terminal of an electronic device equipped with the secondary battery pack. When a charger other than a properly designed charger is directly connected to the charger, it is possible to charge with a charger other than the dedicated charger if the charger terminal arrangement is the same. Had the problem of not being guaranteed. In addition, such a problem is caused by the fact that the identification of the secondary battery is performed mainly on the charger side instead of the secondary battery pack body.
また、信号端子を介して電気信号をやり取りすることで正規な二次電池パックであるか否かの判別を行っているが、信号端子が接触不良などを起こした際には、正規な二次電池パックであっても使用できないといった不具合が生じる。さらに、正規な二次電池パックであるか否かの判別を行っている信号のやり取りを磁気的に行った場合、二次電池パック周囲に存在した強磁性体により誤作動を生じたり、信号のやり取りを光学的に実施した場合には送受信部への埃等付着による誤作動を発生する恐れがある。 In addition, it is determined whether the battery pack is a legitimate secondary battery pack by exchanging electrical signals through the signal terminals, but when the signal terminals cause poor contact, etc. A problem arises that even a battery pack cannot be used. In addition, if the exchange of signals for determining whether or not the battery pack is a legitimate secondary battery pack is performed magnetically, malfunctions may occur due to the ferromagnetic material present around the secondary battery pack, When the exchange is performed optically, there is a risk of malfunction due to adhesion of dust or the like to the transmission / reception unit.
また、特許文献２に開示された方法においては、真贋判定回路に送信部、受信部以外に電源部を内蔵させる必要があり、この真贋判定回路自体が高価なものとなると同時に、真
贋判定回路の電源部に電力不足あるいは不具合が発生した際には、正規な二次電池パックであっても使用できないといった不具合が生じる。
Further, in the method disclosed in Patent Document 2, it is necessary to incorporate a power supply unit in addition to the transmission unit and the reception unit in the authenticity determination circuit. This authenticity determination circuit itself becomes expensive, and at the same time, When power is insufficient or a problem occurs in the power supply unit, a problem arises that even a regular secondary battery pack cannot be used.

It is an object of the present invention to provide a secondary battery that can be transmitted and identified to an electronic device used.

予め角筒形二次電池１２の個別認識情報を格納したＩＣタグ２を、角筒形二次電池１２に内蔵した。角筒形二次電池１２を携帯電話本体１１に装着することで、携帯電話本体１１に内蔵された無線送受信部１３の無線発信回路４より角筒形二次電池１２のＩＣタグ２に電磁波または、マイクロ波を発信し、ＩＣタグ２の無線送受信器１５で受信された電磁波または、マイクロ波をＩＣタグ２の個別識別情報を格納しているメモリ部１４の作動電力として供給する。次に、角筒形二次電池１２の個別識別情報をＩＣタグ２の無線送受信器１５より送信し、角筒形二次電池１２の個別識別情報を携帯電話本体１１に内蔵された無線送受信部１３の無線受信回路５により受信し、個別識別情報を信号処理回路６で信号処理したのち、制御回路７を介して制御出力回路８にて個別識別情報が正規の値であることを認識し、スイッチ回路１０を駆動することにより、充電回路９を形成することで充電可能な状態にした。 The IC tag 2 in which individual recognition information of the rectangular tube secondary battery 12 is stored in advance is built in the rectangular tube secondary battery 12.

Further, instead of the liquid crystal screen display, an indicator lamp may be turned on or blinking, and any warnings may be used as long as they indicate a warning.
次に、図７に示されるブロック図では、電池パック３およびこの電池パック３を装着したハンドキャリータイプのパーソナルコンピュータ（以下ＰＣと称す）本体１１の本発明における一実施の形態である。 Next, the block diagram shown in FIG. 7 shows an embodiment of the present invention of a battery pack 3 and a hand carry type personal computer (hereinafter referred to as PC) main body 11 to which the battery pack 3 is attached.
予め円筒形二次電池１の個別認識情報を格納したＩＣタグ２を円筒形二次電池１の本体部に設置したのち、制御回路７、制御出力回路８、充電回路９、スイッチ回路１０とともに、円筒形二次電池１をパッケージングすることで、ＰＣ本体１１用二次電池パック３を形成した。 After installing the IC tag 2 storing the individual recognition information of the cylindrical secondary battery 1 in the main body of the cylindrical secondary battery 1 in advance, together with the control circuit 7, the control output circuit 8, the charging circuit 9, and the switch circuit 10, The secondary battery pack 3 for the PC main body 11 was formed by packaging the cylindrical secondary battery 1.
二次電池パック３をＰＣ本体１１に装着することで、ＰＣ本体１１に内蔵された無線送受信部１３の無線発信回路４より円筒形二次電池１のＩＣタグ２に電磁波または、マイクロ波を発信し、ＩＣタグ２の無線送受信器１５で受信された電磁波または、マイクロ波をＩＣタグ２の個別識別情報を格納しているメモリ部１４の作動電力として供給する。さらに、円筒形二次電池１の個別識別情報をＩＣタグ２の無線送受信器１５より送信し、円筒形二次電池１の個別識別情報をＰＣ本体１１に内蔵された無線送受信部１３の無線受信回路５により受信し、個別識別情報を信号処理回路６で電気信号に変換される。次いで、二次電池パック３側の制御回路７に電気信号が送られ、制御出力回路８にて個別識別情報が正規の値であることを認識し、スイッチ回路１０を駆動することにより、充電回路９を形成することで、充電可能な状態にした。 By attaching the secondary battery pack 3 to the PC body 11, electromagnetic waves or microwaves are transmitted to the IC tag 2 of the cylindrical secondary battery 1 from the wireless transmission circuit 4 of the wireless transmission / reception unit 13 built in the PC body 11. Then, the electromagnetic wave or the microwave received by the wireless transceiver 15 of the IC tag 2 is supplied as the operating power of the memory unit 14 storing the individual identification information of the IC tag 2. Further, the individual identification information of the cylindrical secondary battery 1 is transmitted from the wireless transceiver 15 of the IC tag 2, and the individual identification information of the cylindrical secondary battery 1 is wirelessly received by the wireless transmission / reception unit 13 built in the PC main body 11. The signal is received by the circuit 5 and the individual identification information is converted into an electric signal by the signal processing circuit 6. Next, an electric signal is sent to the control circuit 7 on the secondary battery pack 3 side, the control output circuit 8 recognizes that the individual identification information is a normal value, and drives the switch circuit 10 to thereby charge the charging circuit. By forming 9, the battery can be charged.
図６と同様に個別認識情報を認識することで、ＰＣ本体１１への電源供給を行ったり、充電可能状態および充電停止状態にする作動を行った。また、個別認識情報を認識されない場合や個別認識情報に基づいた充電状態で充電されなかった場合、装着した二次電池パック３が適合していないこと等の旨をＰＣ本体１１の表示部１７に警告表示させた。 Similar to FIG. 6, by recognizing the individual recognition information, power was supplied to the PC main body 11, or an operation for setting the chargeable state and the charge stop state was performed. Further, when the individual recognition information is not recognized or the battery is not charged in the charging state based on the individual recognition information, the display unit 17 of the PC main body 11 indicates that the attached secondary battery pack 3 is not suitable. A warning was displayed.
ここで、ＩＣタグ２内に格納される個別認識情報としては、ＩＤナンバー以外に例えば、電池の種類、製造元、製造年月日、製造番号、電池品番、定格容量、定格電圧等の一般
的情報は言うに及ばず、この電池個体の製造工程履歴情報を格納することも可能であり、さらに、過充電電圧、過充電電流、過放電電圧、素子温度等の安全性能に関わる情報を格納することも可能であるが、これらに限定されるものではない。また、ＩＣタグ２のＩＤナンバーおよび円筒形二次電池１または角筒形二次電池１２の個別認識情報の少なくとも一つ以上の情報が、暗号化処理されていることにより個別識別情報を書き換えられることに対して保護を行っている。
Here, as the individual recognition information stored in the IC tag 2, in addition to the ID number, for example, general information such as battery type, manufacturer, date of manufacture, serial number, battery product number, rated capacity, rated voltage, etc. Needless to say, it is also possible to store manufacturing process history information of this individual battery, and further store information related to safety performance such as overcharge voltage, overcharge current, overdischarge voltage, element temperature, etc. However, the present invention is not limited to these. Further, the individual identification information can be rewritten by encrypting at least one of the ID number of the IC tag 2 and the individual recognition information of the cylindrical secondary battery 1 or the rectangular secondary battery 12. We are protecting against this.
また、円筒形二次電池１または角筒形二次電池１２および二次電池パック３５に具備されたＩＣタグ２を剥がす行為によりＩＣタグ２は回路的に分断され、個別識別情報を書き換えられることに対して保護も行っている。 Further, the IC tag 2 is divided in a circuit by the act of removing the IC tag 2 provided in the cylindrical secondary battery 1 or the square cylindrical secondary battery 12 and the secondary battery pack 35, and the individual identification information can be rewritten. We are also protecting against this.
ＩＤナンバーを含む個別認識情報をＩＣタグ２内に格納し、かつ、外部信号を受信して起動するＩＣタグ２を円筒形二次電池１または角筒形二次電池１２および二次電池パック３、３５に具備する構成をしているため、無線送受信部１３を設置した電子機器１１からの信号を受信することでＩＣタグ２が起動し、円筒形二次電池１または角筒形二次電池１２の個別識別情報を電子機器１１に送信することで、二次電池１，１２または二次電池パック３、３５を用いた電子機器に適合した電源供給ができ、充電電圧及び電流の異なって充電する電子機器１１にて充電されることなく、安全な円筒形二次電池１または角筒形二次電池１２の充放電を確保することができる。さらに、ＩＣタグ２が円筒形二次電池１または角筒形二次電池１２の個別認識情報を取り出す動作を自ら電源部を持たずに行えることにより、コンパクト化が可能である。 The individual identification information including the ID number is stored in the IC tag 2, and the IC tag 2 that is activated by receiving an external signal is connected to the cylindrical secondary battery 1 or the rectangular secondary battery 12 and the secondary battery pack 3. , 35, the IC tag 2 is activated by receiving a signal from the electronic device 11 in which the wireless transmission / reception unit 13 is installed, and the cylindrical secondary battery 1 or the rectangular secondary battery. By transmitting 12 individual identification information to the electronic device 11, power supply suitable for the electronic device using the secondary battery 1, 12 or the secondary battery pack 3, 35 can be provided, and charging is performed with different charging voltage and current. Therefore, the charging / discharging of the safe cylindrical secondary battery 1 or the rectangular cylindrical secondary battery 12 can be ensured without being charged by the electronic device 11. Furthermore, since the IC tag 2 can perform the operation of extracting the individual recognition information of the cylindrical secondary battery 1 or the rectangular tube secondary battery 12 without having a power supply unit by itself, the IC tag 2 can be made compact.
二次電池または、二次電池を内蔵した二次電池パックに外部信号を受信して起動するＩＣタグを設置し、ＩＣタグに格納された二次電池の個別認識情報を取り出す動作を自ら電源部を持たずに行えることにより、コンパクト化が可能である。また、送受信可能な識別手段を二次電池または、二次電池パックを用いた電子機器側に設けることで、適切な充放電制御を行うことができ、二次電池を安全に充放電することが可能な二次電池、二次電池パックおよびそれを用いた電子機器を提供できる。 Installed an IC tag that activates by receiving an external signal in a secondary battery or a secondary battery pack that incorporates a secondary battery, and the power supply unit performs the operation of retrieving individual identification information of the secondary battery stored in the IC tag. It can be made compact by being able to do without having. Moreover, by providing an identification means capable of transmitting and receiving on the secondary battery or the electronic device side using the secondary battery pack, appropriate charge / discharge control can be performed, and the secondary battery can be charged and discharged safely.
