Description

本発明はＲＦＩＤタグを備えた鉛蓄電池と、その製造方法に関するものである。   The present invention relates to a lead storage battery including an RFID tag and a method for manufacturing the same.

鉛蓄電池は、自動車の始動用、バックアップ電源用といった様々な用途に用いられている。鉛蓄電池は、ニッケル水素蓄電池等のアルカリ蓄電池と比較して良好な自己放電特性を有するが、在庫期間が長期にわたる場合、自己放電分を補うための補充電が必要となる。   Lead-acid batteries are used for various purposes such as starting automobiles and backup power supplies. Lead storage batteries have better self-discharge characteristics than alkaline storage batteries such as nickel metal hydride storage batteries, but supplementary charging is required to compensate for self-discharge when the inventory period is long.

鉛蓄電池では、電池本体や表示ラベル上に充電日の表示を行っているものが殆どであり、この充電日からの経過日数によって、補充電を行っていた。したがって、在庫中の鉛蓄電池について、充電日表示を確認して、充電日からの経過日数を管理する必要があった。   Most lead storage batteries display the date of charging on the battery body or the display label, and the auxiliary charging is performed according to the number of days elapsed from this charging date. Therefore, it was necessary to manage the number of days elapsed from the charging date by checking the charging date display for the lead storage batteries in stock.

充電日表示の確認作業はすべての電池について、充電日表示を確認できる状態とし、目視で確認する必要があり、確認作業日からの逆算によって、充電日からの経過日数を算出しており、手間のかかる作業であった。   Checking the charging date display requires that all batteries be in a state in which the charging date display can be checked and visually confirmed.The number of days elapsed from the charging date is calculated by calculating backward from the checking work day. It took a lot of work.

また、鉛蓄電池が梱包箱に収納されている場合や、梱包箱に収納された鉛蓄電池の１個〜数個がシュリンクフィルムで包装されている場合には、これらの梱包を開梱する作業が生じる。特に、シュリンクフィルム包装の場合には、一旦開梱作業を行うと、包装の復元作業が不可能となってしまうものもあった。   Moreover, when the lead storage battery is stored in a packing box, or when one to several lead storage batteries stored in the packing box are packed with a shrink film, the work of unpacking these packings Arise. In particular, in the case of shrink film packaging, once the unpacking operation is performed, there is a case where the packaging restoration operation becomes impossible.

さらに、補充電作業を行った電池については、補充電日を新たな充電日として管理する必要が生じ、同一補充電日ごとに同一のパレットに電池を保管して在庫管理したり、電池毎に補充電日を別途表示する必要があった。   In addition, for batteries that have undergone supplementary charging work, it is necessary to manage the supplementary charging date as a new charging date, and the batteries are stored on the same pallet for each supplementary charging day for inventory management or for each battery. It was necessary to display the supplementary charging date separately.

一方、上記したような自動車始動用の鉛蓄電池とは異なり、バックアップ電源用に用いられる大容量の産業用鉛蓄電池では、数年〜十数年といった長期の使用期間中、定期的に電池の機能をチェックし、劣化がある程度まで進行したものは交換作業を行う必要がある。   On the other hand, unlike lead-acid batteries for starting automobiles as described above, large-capacity industrial lead-acid batteries used for backup power supplies function regularly during long periods of use such as several years to several tens of years. If the deterioration has progressed to a certain extent, it is necessary to perform replacement work.

定期点検では、電池電圧、内部抵抗、電解液比重等のデータを電池個々に計測し、点検表に記入したり、管理用のコンピュータに入力する等の作業が必要であった。   In the periodic inspection, data such as battery voltage, internal resistance, and electrolyte specific gravity were measured for each battery and entered into an inspection table or entered into a management computer.

一方、製品の在庫管理や点検管理を効率良く行うためのデバイスとしてＲＦＩＤタグ（無線タグ、ＩＣタグ）が知られている。ＲＦＩＤタグは内部にデータ記憶領域を有し、リーダからの電波によって電力を発生させ、データ記憶領域中に格納された任意のデータをリーダに対して発信するデバイスである。   On the other hand, RFID tags (wireless tags, IC tags) are known as devices for efficiently performing product inventory management and inspection management. The RFID tag is a device that has a data storage area inside, generates power by radio waves from the reader, and transmits arbitrary data stored in the data storage area to the reader.

ＲＦＩＤタグと電池とを組み合わせた事例として、例えば特許文献１では、携帯電話機といった電子機器に用いる二次電池にＲＦＩＤタグを組み合わせ、ＲＦＩＤタグ中に二次電池の認証情報を記憶させておくことで、電子機器に装着された二次電池がその機器に適合するものかどうかの認証を行い、不適合品の場合には充電を行わない等の制御を行うことが示されている。
特開２００４−２８９９９５号公報 As an example of combining an RFID tag and a battery, for example, in Patent Document 1, an RFID tag is combined with a secondary battery used in an electronic device such as a mobile phone, and authentication information of the secondary battery is stored in the RFID tag. It is shown that the secondary battery mounted on the electronic device is authenticated whether or not it is compatible with the device, and control is performed such that charging is not performed in the case of a non-conforming product.
JP 2004-289995 A

特許文献１では、二次電池とＲＦＩＤタグを組み合わせることが示されているものの、その具体的な構造については示されていない。特に、携帯電話機に使用される二次電池として想定されるＬｉ二次電池やアルカリ蓄電池と異なり、鉛蓄電池では、使用中に電解液（希硫酸）が漏出したり、酸霧を生じることがある。   In Patent Document 1, although it is shown that a secondary battery and an RFID tag are combined, a specific structure thereof is not shown. In particular, unlike Li secondary batteries and alkaline storage batteries that are assumed as secondary batteries used in mobile phones, lead storage batteries may leak electrolyte (dilute sulfuric acid) or cause acid mist during use. .

特に、鉛蓄電池への補液作業や補充電作業では、鉛蓄電池外装に電解液分が付着したり、急速充電による酸霧が発生する。また、産業用鉛蓄電池においても、長期間トリクル充電した場合に、酸霧が発生したり、極柱封止部や制御弁部から希硫酸電解液が滲出し、ＲＦＩＤタグに硫酸分が付着して動作不良を発生させる要因となる。   In particular, in a replenishing operation or a recharging operation for a lead storage battery, an electrolytic solution adheres to the lead storage battery exterior or acid mist is generated due to rapid charging. In addition, in industrial lead-acid batteries, acid mist is generated when trickle charging is performed for a long period of time, dilute sulfuric acid electrolyte oozes out from the pole column sealing part and the control valve part, and sulfuric acid is attached to the RFID tag. Cause malfunctions.

本発明は、ＲＦＩＤタグを鉛蓄電池に装着した場合においても、希硫酸電解液や酸霧のＦＲＩＤへの付着とこれによるＲＦＩＤタグの動作不良を抑制し、信頼性の高い、ＲＦＩＤタグ付鉛蓄電池を提供するものである。   Even when the RFID tag is mounted on a lead storage battery, the present invention suppresses the adhesion of dilute sulfuric acid electrolyte or acid mist to the FRID and the resulting malfunction of the RFID tag, and is a highly reliable lead storage battery with an RFID tag. Is to provide.

以下、本発明の実施の形態を説明する。   Embodiments of the present invention will be described below.

１．第１の実施形態
図１は、本発明の第１の実施形態による鉛蓄電池１を示す図、図２は鉛蓄電池１の要部断面を示す図である。極板群（図示せず）を収納した電槽２に電槽２の開口部を覆う蓋３が接合されている。なお、図１に示した例は、自動車始動用鉛蓄電池に適用した例を示し、蓋３の上面には、液口に装着され、電池内部と外部との通気性を確保するための排気栓４が装着されている。なお、制御弁式鉛蓄電池に適用する場合、排気栓に替えて制御弁構造を設けることは言うまでもない。 1. First Embodiment FIG. 1 is a diagram showing a lead-acid battery 1 according to a first embodiment of the present invention, and FIG. A lid 3 that covers the opening of the battery case 2 is joined to the battery case 2 that houses an electrode plate group (not shown). The example shown in FIG. 1 shows an example applied to a lead-acid battery for starting an automobile, and an exhaust plug is provided on the upper surface of the lid 3 for a liquid port to ensure air permeability between the inside and outside of the battery. 4 is installed. In addition, when applying to a control valve type lead acid battery, it cannot be overemphasized that a control valve structure is provided instead of an exhaust plug.

本発明の鉛蓄電池１では、その外装に設けた凹部５に非接触式で読み書き可能なＲＦＩＤタグ６が収納される。図２では、外装としての蓋３に凹部５を設け、その中にＲＦＩＤタグ６を収納した例を示している。   In the lead storage battery 1 of the present invention, a non-contact readable / writable RFID tag 6 is accommodated in a recess 5 provided on the exterior thereof. FIG. 2 shows an example in which the recess 3 is provided in the lid 3 as an exterior, and the RFID tag 6 is accommodated therein.

使用するＲＦＩＤタグとしては、一般に市販されているものから適宜選択することができるが、例えば、オムロン社製Ｖ７００−Ｄ１３Ｐ２１形ＩＤタグ（ユーザメモリ容量１１２ｂｙｔｅ）を使用することができる。この形式のＲＦＩＤタグは径２３ｍｍ、厚み１．２ｍｍの薄型コイン形状を有している。したがって、凹部５の形状をこの形状に応じて設定する。   The RFID tag to be used can be appropriately selected from commercially available ones. For example, a V700-D13P21 type ID tag (user memory capacity 112 bytes) manufactured by OMRON can be used. This type of RFID tag has a thin coin shape with a diameter of 23 mm and a thickness of 1.2 mm. Therefore, the shape of the recess 5 is set according to this shape.

なお、凹部５は蓋３もしくは電槽２といった外装上に設けることができる。しかしながら、電槽２に凹部を設けると、電槽２内の容積が減少し、その分、極板群の寸法を減少させる必要が生じ、容量が低下する方向となる。したがって、蓋３の上面の、電槽内容積に影響を及ぼさない位置に凹部５を設けることが好ましい。   The recess 5 can be provided on the exterior such as the lid 3 or the battery case 2. However, when the battery case 2 is provided with a recess, the volume in the battery case 2 is reduced, and accordingly, the dimension of the electrode plate group needs to be reduced, and the capacity is reduced. Therefore, it is preferable to provide the recess 5 at a position on the upper surface of the lid 3 that does not affect the volume of the battery case.

そして、凹部５の開口部を耐酸性を有したシート部材７で覆い、凹部５内を電池外部から液密に封止する。   And the opening part of the recessed part 5 is covered with the sheet member 7 which has acid resistance, and the inside of the recessed part 5 is liquid-tightly sealed from the battery exterior.

一般に自動車始動用鉛蓄電池の電槽・蓋は耐酸性に優れたポリプロピレン樹脂で構成するため、シート部材７もこれと同様、ポリプロピレン樹脂を用いればよい。また、ポリエチレン樹脂も耐酸性を有しており、用いることができる。   In general, since the battery case and lid of the lead-acid battery for starting automobiles are made of polypropylene resin having excellent acid resistance, the sheet member 7 may be made of polypropylene resin as well. Polyethylene resins also have acid resistance and can be used.

ポリプロピレン樹脂、ポリエチレン樹脂等の熱可塑性樹脂でシート部材７を構成する場合、溶着によって、シート部材７が凹部５を覆うよう、蓋３に液密に接合することができる。溶着方法としては、熱板でシート部材７と蓋３の接合部を加熱し、両者を圧接して冷却・固化させたり、超音波溶着により、両者を溶着してもよい。溶着による場合、両者が同一材料であれば、比較的簡便に強固に接合することができ、好ましい。   When the sheet member 7 is made of a thermoplastic resin such as polypropylene resin or polyethylene resin, the sheet member 7 can be liquid-tightly bonded to the lid 3 so as to cover the recess 5 by welding. As a welding method, the joining portion of the sheet member 7 and the lid 3 may be heated with a hot plate, and both may be pressed and cooled / solidified, or both may be welded by ultrasonic welding. In the case of welding, if both are the same material, it can be bonded relatively easily and firmly, which is preferable.

上記した本発明の鉛蓄電池１は、ＲＦＩＤタグ６が電池外装内に液密に封止されるため、電解液や酸霧中に含まれる硫酸分のＲＦＩＤタグへの付着と、これによるＲＦＩＤタグの動作不良を抑制することができる。   In the lead storage battery 1 of the present invention described above, since the RFID tag 6 is sealed in a liquid-tight manner inside the battery exterior, the sulfuric acid contained in the electrolyte or acid mist adheres to the RFID tag, and the RFID tag thus formed It is possible to suppress malfunctions.

本発明の鉛蓄電池１において、ＲＦＩＤタグ６中に充電日、組立日等の製造時期に関する情報や、製品品番といった製品を特定するための情報で必要とする少なくとも一部情報を内部記憶領域に記憶させることができる。   In the lead storage battery 1 of the present invention, at least a part of information necessary for identifying information such as a product date such as a product date or a product date such as a charging date or an assembly date is stored in an internal storage area in the RFID tag 6. Can be made.

ＲＦＩＤタグ６中のデータの読み取りはＲＦＩＤタグリーダを用いて読み取ればよい。ＲＦＩＤタグ６中のデータの読み書きは電波を用いて行われる。したがって、従来行ってきたような、充電日表示等を確認するために鉛蓄電池の梱包を解いたり、鉛蓄電池の位置を移動させたりといった必要がなくなり、読み取り作業負荷を軽減することができる。   Data in the RFID tag 6 may be read using an RFID tag reader. Reading and writing data in the RFID tag 6 is performed using radio waves. Therefore, there is no need to unpack the lead storage battery or move the position of the lead storage battery in order to confirm the charge date display or the like as has been done conventionally, and the reading work load can be reduced.

リーダで読み取った充電日情報から、補充電が必要と判断し、補充電を行った場合には、ＲＦＩＤタグライターを用い、補充電日を充電日情報としてＲＦＩＤタグに書き込めばよい。これにより、従来、別ラベル等で別途に行っていた、補充電日表示を行う必要がないため、在庫管理の負荷を軽減することができる。   When it is determined that supplementary charging is necessary from the charging date information read by the reader and supplementary charging is performed, an RFID tag writer may be used to write the supplementary charging date into the RFID tag as charging date information. Thereby, since it is not necessary to display the supplementary charging date, which has been separately performed with a separate label or the like, it is possible to reduce the load of inventory management.

また、本発明の鉛蓄電池１において、ＲＦＩＤタグ６中に電池の点検情報を記憶させることができる。特にバックアップ用電源に用いる産業用鉛蓄電池では、数年〜十数年にわたる使用期間中の信頼性が必要であり、使用期間中の定期点検が必要となる。定期点検時には、電池電圧、内部抵抗等の諸特性を計測し、記録管理するが、このような定期点検時のデータで必要とする少なくとも一部の情報をＲＦＩＤタグ６に内部記憶として記憶させておけば、電池毎の点検履歴が電池内に記憶できるため、保守管理上、極めて有用である。   Further, in the lead storage battery 1 of the present invention, battery inspection information can be stored in the RFID tag 6. In particular, an industrial lead-acid battery used for a backup power source requires reliability during a period of use ranging from several years to over ten years, and a periodic inspection during the period of use is necessary. During periodic inspection, various characteristics such as battery voltage and internal resistance are measured and recorded and managed. At least a part of information necessary for such data during periodic inspection is stored in the RFID tag 6 as internal storage. If this is done, the inspection history for each battery can be stored in the battery, which is extremely useful for maintenance management.

２．第２の実施形態
図３は、本発明の第２の実施形態による鉛蓄電池１０を示す図、図４および図５は鉛蓄電池１０の要部断面を示す図である。鉛蓄電池１０は第１の実施形態による鉛蓄電池１と同様、極板群（図示せず）を収納した電槽２に電槽２の開口部を覆う蓋３が接合されている。なお、図２に示した例は、自動車始動用鉛蓄電池に適用した例を示し、蓋３の上面には、液口に装着され、電池内部と外部との通気性を確保するための排気栓４が装着されている。なお、制御弁式鉛蓄電池に適用する場合、排気栓に替えて制御弁構造を設けることは言うまでもない。 2. Second Embodiment FIG. 3 is a diagram showing a lead storage battery 10 according to a second embodiment of the present invention, and FIGS. 4 and 5 are cross-sectional views showing the main part of the lead storage battery 10. Similarly to the lead storage battery 1 according to the first embodiment, the lead storage battery 10 includes a battery case 2 housing an electrode plate group (not shown) and a lid 3 that covers the opening of the battery case 2. The example shown in FIG. 2 shows an example applied to a lead-acid battery for starting an automobile. The upper surface of the lid 3 is attached to a liquid port, and an exhaust plug for ensuring air permeability between the inside and outside of the battery. 4 is installed. In addition, when applying to a control valve type lead acid battery, it cannot be overemphasized that a control valve structure is provided instead of an exhaust plug.

本発明の第２の実施形態による鉛蓄電池１０では、電池外装にＲＦＩＤタグ６を載置し、耐酸性部材層１２を備え、一面に粘着剤層１３を形成したシート部材１１で、ＲＦＩＤタグ６を電池外装に固定する。また、ＲＦＩＤタグ６周囲が電池外部から封止された状態とする。   In the lead-acid battery 10 according to the second embodiment of the present invention, the RFID tag 6 is a sheet member 11 having the RFID tag 6 mounted on the battery exterior, the acid-resistant member layer 12 and the adhesive layer 13 formed on one surface. Is fixed to the battery case. In addition, the periphery of the RFID tag 6 is sealed from the outside of the battery.

シート部材１１の構成の一例として、ＰＥＴ樹脂の基材層１１ａをＰＰ樹脂で構成した耐酸性部材層１２とロジンエステル系粘着剤やシリコーン系粘着剤からなる粘着剤層１３を形成したものを用いることができる。粘着剤層１３によって、ＲＦＩＤタグ６と電池外装としての蓋３の表面に粘着することにより、シート部材１１によってＲＦＩＤタグ６が封止・固定された構成を有する。なお、本実施形態においても、ＲＦＩＤタグ６を蓋３上で固定した例を述べたが、電槽側壁といった、他の電池外装面にＲＦＩＤタグ６を封止・固定することもできる。   As an example of the structure of the sheet member 11, an acid resistant member layer 12 made of a PP resin and a pressure sensitive adhesive layer 13 made of a rosin ester pressure sensitive adhesive or a silicone pressure sensitive adhesive is used. be able to. The RFID tag 6 is sealed and fixed by the sheet member 11 by adhering to the RFID tag 6 and the surface of the lid 3 as the battery exterior by the adhesive layer 13. In the present embodiment, the example in which the RFID tag 6 is fixed on the lid 3 has been described. However, the RFID tag 6 can be sealed and fixed to another battery exterior surface such as a battery wall.

第２の実施形態による鉛蓄電池１０は、ＲＦＩＤタグ６が耐酸性部材層１２によって、硫酸分との接触が防止できるため、第１の実施形態による鉛蓄電池１と同様、ＲＦＩＤタグ６の硫酸付着による動作不良を抑制することができる。なお、ＲＦＩＤタグ６の厚み寸法によっては、蓋３よりの突出寸法Ａが大きくなるため、第１の実施形態の鉛蓄電池１のように、蓋３に凹部を設け、ＲＦＩＤタグ６を配置してもよい。   Since the lead-acid battery 10 according to the second embodiment can prevent the RFID tag 6 from contacting the sulfuric acid component by the acid-resistant member layer 12, the sulfuric acid adheres to the RFID tag 6 as with the lead-acid battery 1 according to the first embodiment. It is possible to suppress malfunction due to the above. Depending on the thickness dimension of the RFID tag 6, the protruding dimension A from the lid 3 becomes large. Therefore, as in the lead storage battery 1 of the first embodiment, the lid 3 is provided with a recess, and the RFID tag 6 is disposed. Also good.

また、第２の実施形態による鉛蓄電池１０に設けられたＲＦＩＤタグ６にも第１の実施形態と同様の情報をその内部記憶領域に記憶させることができ、鉛蓄電池の在庫管理・点検管理の作業性を向上することができる。   Further, the RFID tag 6 provided in the lead storage battery 10 according to the second embodiment can also store the same information as that of the first embodiment in its internal storage area. Workability can be improved.

３．第３の実施形態
本発明の第３の実施形態による鉛蓄電池は、第１の実施形態の鉛蓄電池１のシート部材７上もしくは第２の実施形態の鉛蓄電池１０のシート部材１１上に電池品番、説明文等を表示したこと構成を有する。 3. Third Embodiment A lead-acid battery according to a third embodiment of the present invention has a battery product number on the sheet member 7 of the lead-acid battery 1 of the first embodiment or on the sheet member 11 of the lead-acid battery 10 of the second embodiment. , A description is displayed.

すなわち、シート部材７（もしくはシート部材１１）上に電池品番等の製品情報や、説明文等の情報の少なくとも一部を表示することにより、これらに製品銘板（製品ラベル）としての機能を持たせたものである。これにより、シート部材７（もしくはシート部材１１）と製品銘板（ラベル）とを個別に設ける必要がなく、部品点数の削減や、製造工程の工数削減が可能である。   That is, by displaying at least a part of the product information such as the battery product number and the information such as the description on the sheet member 7 (or the sheet member 11), these are given a function as a product nameplate (product label). It is a thing. Thereby, it is not necessary to provide the sheet member 7 (or the sheet member 11) and the product nameplate (label) separately, and it is possible to reduce the number of parts and the number of manufacturing steps.

なお、シート部材７（シート部材１１）はＲＦＩＤタグ６の読み書き時の電波を透過させる必要がある。シート部材７（シート部材１１）上にＡｌといった金属薄膜蒸着層といった電波透過の妨げとなるような層の形成、あるいは金属成分を含む塗料の塗布は避けるべきである。   The sheet member 7 (sheet member 11) needs to transmit radio waves when the RFID tag 6 is read and written. Formation of a layer that hinders radio wave transmission such as a metal thin film deposition layer such as Al on the sheet member 7 (sheet member 11) or application of a paint containing a metal component should be avoided.

４．第４の実施形態
本発明の第４の実施形態は、前記した第３の実施形態による鉛蓄電池１０の製造方法に関するものである。 4). 4th Embodiment 4th Embodiment of this invention is related with the manufacturing method of the lead acid battery 10 by above described 3rd Embodiment.

すなわち、第３の実施形態による鉛蓄電池のシート部材７（もしくはシート部材１１）上の表示を当初から行わない状態で電池とし、その後、レーザ印刷方式やインクジェット方式により、加飾処理を施して表示を形成し、表示された情報の中で所望とする情報をＲＦＩＤタグライターでＲＦＩＤタグ６に書き込み処理を行う。例えば、製品品番と充電日等の所望とする表示をシート部材７（もしくはシート部材１１）上に印刷し、ただちにＲＦＩＤタグ６にこの表示の少なくとも一部に対応する情報、例えば充電日情報を内部記憶情報として書き込み処理を行う。   In other words, the battery on the sheet member 7 (or the sheet member 11) of the lead storage battery according to the third embodiment is not used from the beginning, and the battery is then subjected to decoration processing by a laser printing method or an ink jet method. The desired information among the displayed information is written into the RFID tag 6 by the RFID tag writer. For example, a desired display such as a product number and a charging date is printed on the sheet member 7 (or the sheet member 11), and information corresponding to at least a part of the display, for example, charging date information is immediately stored in the RFID tag 6. Write processing is performed as stored information.

これにより、シート部材７（シート部材１１）は異なった型式の鉛蓄電池間で共通部品化ができるため、部品価格の低減が可能となる。また、共通部品化により鉛蓄電池型式毎の在庫管理が不要となるため、管理コストを削減することができる。   Thereby, since the sheet member 7 (sheet member 11) can be made into a common part among different types of lead-acid batteries, the part price can be reduced. In addition, since the inventory management for each lead storage battery type is not required due to the common parts, the management cost can be reduced.

また、部品の取り違い等による、シート部材７（シート部材１１）上の表示情報とＲＦＩＤタグ６中の記憶情報との間の不整合を防止することができる。   In addition, it is possible to prevent inconsistency between the display information on the sheet member 7 (sheet member 11) and the stored information in the RFID tag 6 due to component misplacement or the like.

ＲＦＩＤタグ６への書き込み工程２１と、シート部材７（シート部材１１）への印刷工程２２は図６に示したような、表示・書き込みすべき情報を入力する情報入力ステップ２３を有し、情報入力ステップ２３で入力された情報を書き込み工程２１と印刷工程２２で出力されるよう制御すれば、上記のような不整合を防止することができる。また、図６では書き込み工程２１が印刷工程２２に先行しているが、この逆順で工程を流すことももちろん可能である。   The writing process 21 to the RFID tag 6 and the printing process 22 to the sheet member 7 (sheet member 11) have an information input step 23 for inputting information to be displayed / written as shown in FIG. If the information input in the input step 23 is controlled so as to be output in the writing step 21 and the printing step 22, the above inconsistency can be prevented. In FIG. 6, the writing process 21 precedes the printing process 22, but it is of course possible to flow the processes in the reverse order.

以上、本発明によれば、信頼性に優れたＲＦＩＤタグ付鉛蓄電池を提供でき、始動用鉛蓄電池や産業用鉛蓄電池の在庫管理・点検管理に好適である。   As described above, according to the present invention, a lead-acid storage battery with an RFID tag having excellent reliability can be provided, which is suitable for inventory management / inspection management of a start-up lead storage battery or an industrial lead storage battery.
