　図１は、鉛バッテリー再生装置１０を説明する図である。
　図１に例示するように、鉛バッテリー再生装置１０は、タッチパネル２、及び、配線４を有する。
　鉛バッテリー再生装置１０は、劣化した鉛バッテリーを再生する装置である。ここで、劣化した鉛バッテリーとは、長期間充電と放電とを繰り返していくことにより、結晶化したサルフェーション（硫酸鉛）が硬質化し、硬質化したサルフェーションが電極板の表面に増殖していくことで充電効率が低下したバッテリーである。また、鉛バッテリーの再生とは、バッテリーの劣化原因であるサルフェーションを取り除くことにより、劣化した鉛バッテリーが新品とほぼ同等の性能に回復することをいう。なお、鉛バッテリー再生装置１０の形状は、特に限定するものではない。鉛バッテリー再生装置１０は、配線４を通して、鉛バッテリー７のプラス端子５、及び、マイナス端子６と、電気的に接続される。鉛バッテリー再生装置１０は、配線４を通して、鉛バッテリー７に対して充電を行う。また、鉛バッテリー再生装置１０は、配線４を通して、鉛バッテリー７を放電させる。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As illustrated in FIG. 1, the lead battery reproducing device 10 has a touch panel 2 and wires 4.
The lead battery recycling device 10 is a device for recycling a deteriorated lead battery. Here, a deteriorated lead battery means that the crystallized sulfation (lead sulfate) hardens by repeated charging and discharging for a long time, and the hardened sulfation multiplies on the surface of the electrode plate. This is a battery with reduced charging efficiency. Regeneration of a lead battery refers to the recovery of a deteriorated lead battery to almost the same performance as a new one by removing sulfation, which is a cause of battery deterioration. In addition, the shape of the lead battery reproducing device 10 is not particularly limited. The lead battery regeneration device 10 is electrically connected to the plus terminal 5 and the minus terminal 6 of the lead battery 7 through the wiring 4. The lead battery regeneration device 10 charges the lead battery 7 through the wiring 4. In addition, the lead battery recycling device 10 discharges the lead battery 7 through the wiring 4.
　タッチパネル２は、例えば、鉛バッテリー再生装置１０の表示装置、及び、入力装置として機能するディスプレイである。タッチパネル２は、ソフトキーやメッセージなどを表示する。 The touch panel 2 is, for example, a display functioning as a display device of the lead battery reproducing device 10 and an input device. The touch panel 2 displays soft keys, messages, and the like.
　配線４は、鉛バッテリー再生装置１０と、鉛バッテリー７のプラス端子５、及び、マイナス端子６と、電気的に接続するための配線である。 The wiring 4 is a wiring for electrically connecting the lead battery regenerating apparatus 10 and the plus terminal 5 and the minus terminal 6 of the lead battery 7.
　鉛バッテリー７は、例えば、充電式鉛蓄電池である。具体的には、鉛バッテリー７は、例えば、自動車のエンジンスターター用に使用されているオープンタイプ、メンテナンスフリータイプ、ＡＧＭ（Ａｂｓｏｒｂｅｄ　Ｇｌａｓｓ　Ｍａｔ）、ジェル方式等の種類のバッテリーである。また、鉛バッテリー７は、カルシウムバッテリー、シルバーバッテリー、ハイブリッドバッテリーであっても良い。鉛バッテリー７は、配線４を通して、鉛バッテリー再生装置１０と電気的に接続される。 The lead battery 7 is, for example, a rechargeable lead storage battery. Specifically, the lead battery 7 is, for example, a battery of an open type, a maintenance-free type, an AGM (Absorbed Glass Mat), a gel type, or the like, which is used for an engine starter of an automobile. Further, the lead battery 7 may be a calcium battery, a silver battery, or a hybrid battery. The lead battery 7 is electrically connected to the lead battery reproducing device 10 through the wiring 4.
　図２は、鉛バッテリー再生装置１０の機能を説明する図である。
　図２に例示するように、本例の鉛バッテリー再生装置１０は、廃棄判定部１０１と、サルフェーション除去充電部１０２と、放電部１０３と、回数判定部１０４と、充電部１０５と、表示部１０６とを有する。また、廃棄判定部１０１、サルフェーション除去充電部１０２、放電部１０３、回数判定部１０４、充電部１０５、及び、表示部１０６は、鉛バッテリー再生装置１０の内部に設けられた電気回路により実現される。 FIG. 2 is a diagram illustrating functions of the lead battery reproducing device 10.
As illustrated in FIG. 2, the lead battery regeneration device 10 of the present example includes a discard determination unit 101, a sulfation removal charging unit 102, a discharge unit 103, a number-of-times determination unit 104, a charging unit 105, and a display unit 106. And In addition, the discarding determination unit 101, the sulfation removal charging unit 102, the discharging unit 103, the number-of-times determining unit 104, the charging unit 105, and the display unit 106 are realized by an electric circuit provided inside the lead battery regeneration device 10. .
　廃棄判定部１０１は、サルフェーション除去充電部１０２による充電前に、鉛バッテリー７の電圧の電圧値に基づいてバッテリーを廃棄するか否かを判定する。廃棄判定部１０１は、より好ましくは、鉛バッテリー７の電圧の電圧値が１０Ｖ以上１１Ｖ以下の電圧値以下である場合に、バッテリーを廃棄すると判定する。本実施例では、廃棄判定部１０１は、鉛バッテリー７の電圧の電圧値が１０．５Ｖ以下である場合に、バッテリーを廃棄すると判定する。これにより、ユーザは、サルフェーション除去充電部１０２による充電よりも前にバッテリーの廃棄を判断することができ、無駄な充電を省くことができる。 The discard determination unit 101 determines whether or not to discard the battery based on the voltage value of the lead battery 7 before charging by the sulfation removal charging unit 102. More preferably, when the voltage value of the lead battery 7 is equal to or less than 10 V and equal to or less than 11 V, the discard determination unit 101 determines to discard the battery. In this embodiment, when the voltage value of the lead battery 7 is 10.5 V or less, the discard determination unit 101 determines to discard the battery. Accordingly, the user can determine the disposal of the battery before charging by the sulfation removal charging unit 102, and can save useless charging.
　サルフェーション除去充電部１０２は、廃棄判定部１０１による判定結果に基づいて、鉛バッテリー再生装置１０から鉛バッテリー７に対して、電流値２Ａ以上２０Ａ以下の直流のベース電流と周波数９ｋＨｚ以上１１ｋＨｚ以下の方形波のパルス電流とを重畳させた充電電流を流すことにより、９分以上１１分以下の間で鉛バッテリー７の充電を行う。本実施例では、サルフェーション除去充電部１０２は、電流値４Ａ以上５Ａ以下、具体的には電流値４．２Ａの直流のベース電流と周波数１０ｋＨｚの方形波のパルス電流とを重畳させた充電電流を流すことにより、充電が連続して１０分経過するまで鉛バッテリー７の充電を行う。サルフェーション除去充電部１０２は、このパルス電流による電気的振動を鉛バッテリー７に加えることにより、鉛バッテリー７の劣化原因であるサルフェーションを除去することができる。
　ただし、サルフェーション除去充電部１０２は、この充電開始前において、廃棄判定部１０１がバッテリーを廃棄すると判定した場合、充電は行わない。 Based on the determination result by the discard determination unit 101, the sulfation removal charging unit 102 applies a DC base current having a current value of 2A to 20A and a square having a frequency of 9kHz to 11kHz to the lead battery 7 from the lead battery regeneration device 10. The lead battery 7 is charged for a period of 9 minutes or more and 11 minutes or less by flowing a charging current in which the pulse current of the wave is superimposed. In the present embodiment, the sulphation removal charging unit 102 generates a charging current obtained by superimposing a DC base current having a current value of 4 A or more and 5 A or less, specifically, a current value of 4.2 A and a square wave pulse current having a frequency of 10 kHz. By flowing, the lead battery 7 is charged until 10 minutes have passed continuously. The sulfation removal charging unit 102 can remove the sulfation that is the cause of the deterioration of the lead battery 7 by applying the electric vibration due to the pulse current to the lead battery 7.
However, before the start of charging, if the discard determination unit 101 determines that the battery is to be discarded, the sulfation removal charging unit 102 does not perform charging.
　放電部１０３は、鉛バッテリー７から鉛バッテリー再生装置１０に対して、サルフェーション除去充電部１０２により充電した鉛バッテリー７の電圧の電圧値が１６．３Ｖ以下となるまで、または、９分以上１１分以下の間の時間が経過するまで放電を行う。より好適には、放電部１０３は、鉛バッテリー７の電圧の電圧値が１２．８Ｖ以上１５．８Ｖ以下となるまで、または、放電が連続して９分以上１１分以下の間の時間が経過するまで放電を行う。本実施例では、サルフェーション除去部１０１は、鉛バッテリー７の電圧の電圧値が１２．８Ｖとなるまで、または、放電が連続して１０分経過するまで放電を行う。 The discharging unit 103 supplies the lead battery 7 from the lead battery 7 to the lead battery reproducing device 10 until the voltage value of the lead battery 7 charged by the sulfation removal charging unit 102 becomes 16.3 V or less, or 9 minutes to 11 minutes. Discharge is performed until the following time elapses. More preferably, the discharging unit 103 determines whether the voltage value of the lead battery 7 becomes 12.8 V or more and 15.8 V or less, or the time during which discharge is continuously performed for 9 to 11 minutes. Discharge until complete. In the present embodiment, the sulfation removal unit 101 performs the discharge until the voltage value of the voltage of the lead battery 7 becomes 12.8 V, or until the discharge has continued for 10 minutes.
　ここで、サルフェーション除去充電部１０２、及び、放電部１０３は、このサルフェーション除去部１０１による充電、及び、放電部１０３による放電の間に、休止期間を設けることにより、鉛バッテリー７が充電、及び、放電で発生する熱により劣化することを防止することができる。 Here, the sulphation removal charging unit 102 and the discharging unit 103 provide a pause period between the charging by the sulphation removing unit 101 and the discharging by the discharging unit 103, so that the lead battery 7 is charged and Deterioration due to heat generated by discharge can be prevented.
　回数判定部１０４は、サルフェーション除去充電部１０２による充電、及び、放電部１０３による放電を１５回以下、より好ましくは９回以上１１回以下繰り返されたか否かを判定する。本実施例では、回数判定部１０４は、サルフェーション除去充電部１０２による充電、及び、放電部１０３による放電を１０回繰り返されたか否かを判定する。
ここで、サルフェーション除去の効果は、サルフェーション除去充電部１０２による充電、及び、放電部１０３による放電の繰り返しの回数に比例して高くなるものではない。充電、及び、放電を１２回以上繰り返しても、充電、及び、放電に要する時間の割には効果が見られず、また、８回以下ではバッテリーの劣化状態によってはサルフェーションを除去し切れない場合がある。 The number-of-times determining unit 104 determines whether the charging by the sulfation removal charging unit 102 and the discharging by the discharging unit 103 have been repeated 15 times or less, more preferably 9 times or more and 11 times or less. In the present embodiment, the number-of-times determining unit 104 determines whether the charging by the sulfation removal charging unit 102 and the discharging by the discharging unit 103 have been repeated 10 times.
Here, the effect of removing sulfation does not increase in proportion to the number of repetitions of charging by the sulfation removing charging unit 102 and discharging by the discharging unit 103. When charging and discharging are repeated 12 times or more, no effect is seen for the time required for charging and discharging, and when 8 times or less, sulfation cannot be completely removed depending on the deterioration state of the battery. There is.
　充電部１０５は、放電部１０３により放電した鉛バッテリー７に対して、鉛バッテリー７の電圧の電圧値が１６．３Ｖ以下となるまで、鉛バッテリー再生装置１０から鉛バッテリー７に対して、一定の電流（以下、定電流という）で鉛バッテリー７の充電を行う。定電流の電流値は、電流値２Ａ以上２０Ａ以下の範囲であり、再生する鉛バッテリー７の容量に応じて適宜選択される。本実施例の充電部１０５は、鉛バッテリー７の電圧の電圧値が１２．８Ｖ以上１５．８Ｖ以下となるまで、電流値４Ａ以上５Ａ以下の定電流で鉛バッテリー７の充電を行う。具体的には、充電部１０５は、鉛バッテリー７の電圧の電圧値が１２．８Ｖとなるまで、電流値４．２Ａの定電流で鉛バッテリー７の充電を行う。ただし、充電部１０５は、充電を行ってから６時間を経過した場合は、鉛バッテリー７の電圧の電圧値が１２．６Ｖ以上１６．３Ｖ以下とならなくても、鉛バッテリー７の充電を中止する。本実施例では、充電部１０５は、充電を行ってから６時間を経過した場合は、鉛バッテリー７の電圧の電圧値が１２．８Ｖとならなくても、鉛バッテリー７の充電を中止する。 The charging unit 105 controls the lead battery 7 from the lead battery regeneration device 10 until the voltage value of the lead battery 7 discharged from the discharging unit 103 becomes 16.3 V or less. The lead battery 7 is charged with a current (hereinafter, referred to as a constant current). The current value of the constant current ranges from 2 A to 20 A, and is appropriately selected according to the capacity of the lead battery 7 to be reproduced. The charging unit 105 of this embodiment charges the lead battery 7 with a constant current of 4 A to 5 A until the voltage value of the lead battery 7 becomes 12.8 V or more and 15.8 V or less. Specifically, the charging unit 105 charges the lead battery 7 with a constant current of 4.2 A until the voltage value of the lead battery 7 becomes 12.8 V. However, the charging unit 105 stops charging the lead battery 7 when six hours have elapsed since charging, even if the voltage value of the lead battery 7 does not become 12.6 V or more and 16.3 V or less. I do. In the present embodiment, the charging unit 105 stops charging the lead battery 7 when six hours have elapsed after charging, even if the voltage value of the lead battery 7 does not become 12.8 V.
　また、この鉛バッテリー７の定電流充電後、充電部１０５は、鉛バッテリー再生装置１０から鉛バッテリー７に対して、１６．３Ｖ以下の一定の電圧値である電圧（以下、定電圧という）を維持するように鉛バッテリー再生装置１０から鉛バッテリー７に流れる電流の電流値を２Ａ以上２０Ａ以下の範囲内で既定の電流値から徐々に電流値を下げ、適正な電流値となるまで鉛バッテリー７の充電を行う。より好適には、充電部１０５は、１２．８Ｖ以上１５．８Ｖ以下の一定の電圧値を維持するように鉛バッテリー７の充電を行う。これにより、鉛バッテリー７におけるバッテリー液の比重（液中に含まれる希硫酸濃度）の値は１．２６以上まで上昇する。ここで、定電圧の電圧値が１６．３Ｖを超える場合、鉛バッテリー７が壊れる可能性がある。また、定電圧の電圧値が１２．６Ｖ未満である場合、鉛バッテリー７におけるバッテリー液の比重の値を上昇させる点で効率が悪い。本実施例では、充電部１０５は、１２．８Ｖの定電圧を維持するように鉛バッテリー７から鉛バッテリー再生装置１０に流れる電流の電流値が電流値４．２Ａから徐々に電流値を下げ、適正な電流値となるまで鉛バッテリー７の充電を行う。 After the constant current charging of the lead battery 7, the charging unit 105 applies a voltage (hereinafter, referred to as a constant voltage) having a constant voltage value of 16.3 V or less to the lead battery 7 from the lead battery reproducing device 10. The current value of the current flowing from the lead battery regenerating apparatus 10 to the lead battery 7 is gradually reduced from a predetermined current value in a range of 2 A to 20 A so as to maintain the current value, and the lead battery 7 is maintained until an appropriate current value is obtained. Charge. More preferably, charging section 105 charges lead battery 7 so as to maintain a constant voltage value of 12.8 V or more and 15.8 V or less. As a result, the value of the specific gravity (the concentration of dilute sulfuric acid contained in the liquid) of the battery liquid in the lead battery 7 increases to 1.26 or more. Here, when the voltage value of the constant voltage exceeds 16.3 V, the lead battery 7 may be broken. Further, when the voltage value of the constant voltage is less than 12.6 V, the efficiency is poor in that the value of the specific gravity of the battery liquid in the lead battery 7 is increased. In the present embodiment, the charging unit 105 gradually reduces the current value of the current flowing from the lead battery 7 to the lead battery regeneration device 10 from the current value of 4.2 A so as to maintain the constant voltage of 12.8 V, The lead battery 7 is charged until the current value becomes appropriate.

　図４に例示するように、ステップ１００（Ｓ１００）において、鉛バッテリー再生装置１０における廃棄判定部１０１は、鉛バッテリー７の電圧の電圧値が１０．５Ｖより大きいか否かを判定する。鉛バッテリー７の電圧の電圧値が１０．５Ｖより大きい場合（Ｓ１１０：Ｙｅｓ）にバッテリーの再生処理（Ｓ１０）は、Ｓ１１０に移行し、鉛バッテリー７の電圧の電圧値が１０．５Ｖ以下である場合（Ｓ１１０：Ｎｏ）に、バッテリー再生処理（Ｓ１０）は、Ｓ１０５に移行する。 FIG. 4 is a flowchart illustrating a battery regeneration process (S10) in the lead battery regeneration device 10.

As illustrated in FIG. 4, in step 100 (S100), the discard determination unit 101 in the lead battery regeneration device 10 determines whether the voltage value of the lead battery 7 is greater than 10.5V. When the voltage value of the voltage of the lead battery 7 is greater than 10.5 V (S110: Yes), the battery regeneration process (S10) proceeds to S110, and the voltage value of the voltage of the lead battery 7 is 10.5V or less.

When the number of times of charging by the sulfation removing unit 102 and the number of times of discharging by the discharging unit 103 each reach 10 times (S125: Yes), the battery regeneration process (S10) proceeds to S130, and the charging by the sulfation removing unit 102. When the number of times of discharge by the discharge unit 103 has not reached 10 times (S125: No), the battery regeneration process (S10) proceeds to S110.

When the voltage value of the lead battery 7 is 12.8 V or more, or when the constant current charging time exceeds 6 hours (S135: Yes), the battery regeneration process (S10) proceeds to S140. If the voltage value of the lead battery 7 is less than 12.8 V and the constant current charging time is less than 6 hours (S135: No), the battery regeneration process (S10) proceeds to S130.

When the constant current charging time exceeds 6 hours (S125: Yes), the battery regeneration process (S10) proceeds to S145, and when the constant current charging time is within 6 hours (S150: No). Then, the battery regeneration process (S10) proceeds to S150.

Accordingly, the user checks whether there is a defect in the connection method of the lead battery 7 and whether the type of the lead battery 7 is out of conformity. The user can judge that the battery is defective and discard the lead battery 7 when there is no defect in the connection method of the battery and when there is no out of conformity of the battery type.
　ステップ１５０（Ｓ１５０）において、充電部１０５は、鉛バッテリー再生装置１０から鉛バッテリー７に対して、電圧値１２．８Ｖの一定の電圧を維持するように鉛バッテリー７の充電を行う。 In step 150 (S150), the charging unit 105 charges the lead battery 7 from the lead battery reproducing device 10 to the lead battery 7 so as to maintain a constant voltage of 12.8V.
　ステップ１５５（Ｓ１５５）において、充電部１０５は、鉛バッテリー７から鉛バッテリー再生装置１０に流れる電流の電流値が適正な電流値であるか否か、又は、定電圧充電時間が５時間以上か否かを判定する。鉛バッテリー７から鉛バッテリー再生装置１０に流れる電流値が適正な電流値以下、又は、定電圧充電時間が５時間以上である場合（Ｓ１５５：Ｙｅｓ）に、バッテリーの再生処理（Ｓ１０）は、Ｓ１６０に移行し、鉛バッテリー７から鉛バッテリー再生装置１０に流れる電流の電流値が適正な電流値より大きく、かつ、定電圧充電時間が５時間未満である場合（Ｓ１５５：Ｎｏ）に、バッテリーの再生処理（Ｓ１０）は、Ｓ１５０に移行する。 In step 155 (S155), the charging unit 105 determines whether the current value of the current flowing from the lead battery 7 to the lead battery reproducing device 10 is an appropriate current value, or whether the constant voltage charging time is 5 hours or more.
