Description
本発明は、バックアップ用途に用いられる制御弁式鉛蓄電池の制御方法、及び制御装置に関する。 The present invention relates to a control method and a control device for a control valve type lead storage battery used for backup.
鉛蓄電池の充電方法には、定電流充電、定電圧充電等の様々な方法がある。車両に搭載される鉛蓄電池に対しては、定電圧充電時の電流値と時間の関係から近似関数を求め、過去の近似関数に基づき定電圧充電時の実測値との誤差を予測し、予測した誤差を、充電不足及び過充電の回避に役立てる技術が提案されている（例えば特許文献１参照）。 There are various methods for charging a lead storage battery, such as constant current charging and constant voltage charging. For lead-acid batteries installed in vehicles, an approximate function is obtained from the relationship between the current value and the time during constant voltage charging, and the error between the measured value during constant voltage charging is predicted based on the past approximation function A technique has been proposed in which the above error is used for avoiding insufficient charging and overcharging (for example, refer to Patent Document 1).
鉛蓄電池には、停電時のバックアップ電源に用いられる制御弁式鉛蓄電池がある。この制御弁式鉛蓄電池は、例えば、バックアップに備えて自己放電分を補うように浮動充電され、バックアップによって放電した後に回復充電される。また、バックアップ用途で用いられる制御弁式鉛蓄電池は、液式(ベント式)鉛蓄電池のような均等充電は一般的に行われない。 As a lead-acid battery, there is a control valve type lead-acid battery used as a backup power source at the time of power failure. This control valve type lead-acid battery is, for example, floating-charged so as to make up for self-discharge in preparation for backup, and then recovery-charged after discharging by backup. In addition, the control valve type lead-acid battery used for backup is generally not uniformly charged like the liquid type (vent type) lead-acid battery.
バックアップ用途の制御弁式鉛蓄電池は、期待寿命が１０年を超える場合がある。しかし、停電が計画的に行われる事態（いわゆる計画停電）が発生した場合、又は、電池の状態をチェックするために定期的に放電を行った場合には、放電回数が想定回数よりも多くなり、期待される寿命を満足しないおそれが生じる。 A control valve type lead-acid battery for backup use may have an expected life of more than 10 years. However, if a power outage occurs in a planned manner (so-called planned power outage), or if the battery is regularly discharged to check the battery status, the number of discharges will exceed the expected number. , The expected life may not be satisfied.
寿命低下を抑制すべく、特許文献１に記載の車両用鉛蓄電池の制御技術を適用し、充電不足及び過充電による寿命低下を抑える対応が考えられる。しかし、制御が複雑になってしまう、というデメリットがある。
そこで、本発明は、バックアップ用途の制御弁式鉛蓄電池を、簡易な制御で寿命低下を抑制することを目的としている。
In order to suppress the shortening of the life, it is conceivable to apply the control technology of the lead acid battery for a vehicle described in Patent Document 1 to suppress the shortening of the life due to insufficient charging and overcharging. However, there is a disadvantage that the control becomes complicated.
Therefore, an object of the present invention is to prevent the life of a control valve type lead storage battery for backup use from being reduced by simple control.
上記目的を達成するために、本発明は、バックアップに備えて制御弁式鉛蓄電池を満充電状態に充電し、バックアップによって放電した後に前記制御弁式鉛蓄電池の回復充電を行う制御弁式鉛蓄電池の制御方法において、前記回復充電として、充電電圧を値Ｘ、充電時間を値Ｙ［ｈｒ］とした定電圧充電を行い、値Ｘ、値Ｙは、Ｘ＝２．３Ｖ／セル〜２．４Ｖ／セル、−１２０Ｘ＋２９６≦Ｙ≦−１２０Ｘ＋３０４、の条件を満たすことを特徴とする。 In order to achieve the above-mentioned object, the present invention provides a control valve type lead storage battery in which a control valve type lead storage battery is charged to a full charge state in preparation for backup, and then the control valve type lead storage battery is recharged after discharging by backup. In the above control method, constant voltage charging with a charging voltage of a value X and a charging time of a value Y [hr] is performed as the recovery charging, and the value X and the value Y are X=2.3V/cell to 2.4V. /Cell, −120X+296≦Y≦−120X+304.
上記構成において、充電時間である値Ｙは、計画停電の時間間隔よりも短い時間に設定されることを特徴とする。 In the above configuration, the value Y, which is the charging time, is set to a time shorter than the time interval of the planned power outage.
また、本発明は、バックアップに備えて制御弁式鉛蓄電池を満充電状態に充電し、バックアップによって放電した後に前記制御弁式鉛蓄電池の回復充電を行う制御弁式鉛蓄電池の制御装置において、前記回復充電として、充電電圧を値Ｘ、充電時間を値Ｙ［ｈｒ］とした定電圧充電を行い、値Ｘ、値Ｙは、Ｘ＝２．３Ｖ／セル〜２．４Ｖ／セル、−１２０Ｘ＋２９６≦Ｙ≦−１２０Ｘ＋３０４、の条件を満たすことを特徴とする。 Further, the present invention provides a control valve type lead storage battery control device for charging the control valve type lead storage battery to a fully charged state in preparation for backup and performing recovery charging of the control valve type lead storage battery after discharging by backup. As the recovery charge, constant voltage charge is performed with the charge voltage as the value X and the charge time as the value Y [hr], and the value X and the value Y are X=2.3 V/cell to 2.4 V/cell, −120X+296≦. It is characterized in that the condition of Y≦−120X+304 is satisfied.
本発明では、バックアップ用途の制御弁式鉛蓄電池を、簡易な制御で寿命を延ばすことができる。 According to the present invention, it is possible to extend the life of a control valve type lead-acid battery for backup use with simple control.
以下、本発明の一実施の形態について説明する。
図１は本発明の制御方法を適用した電池システム１０を示すブロック図である。
この電池システム１０は、停電時に負荷１１に電力を供給するシステムであり、バックアップ電源となる蓄電池１２と、商用電源１３からの電力によって蓄電池１２を充電する充電制御装置１５とを備えている。負荷１１は、商用電源１３からの電力で作動する設備、又は電子機器である。蓄電池１２は、バックアップ対象の負荷１１に合わせて仕様（容量等）が設定された電池であり、複数の制御弁式鉛蓄電池１２Ａによって構成されている。
An embodiment of the present invention will be described below.
FIG. 1 is a block diagram showing a
The
充電制御装置１５は、停電検出部２１、充電部２２、及び演算処理部２３などを備える、停電検出部２１は、商用電源１３からの電力供給の停止・開始を検出することによって、停電の開始・終了を検出する。充電部２２は、充電用の回路などを有し、演算処理部２３の制御の下、充電電圧、充電電流、及び充電時間等を設定する。
The
演算処理部２３は、内蔵メモリに記憶された制御プログラムを実行することによって充電制御装置１５の各部を制御する。また、この充電制御装置１５は、蓄電池１２の状態（電圧、温度等）を検出する回路、各種の情報を表示する表示部、及びユーザー指示を入力する指示入力部などを備えていてもよい。
The
充電制御装置は、停電が発生していない場合、蓄電池の自己放電分を補うように浮動充電を行う。浮動充電電流は、例えば、（５／１０，０００）Ｃ〜（１／１０００）Ｃ（Ｃは蓄電池の定格容量）程度であり、非常に小さい。また、充電制御装置は、停電を検出した後に停電の停止（電力の復旧に相当）を検出すると、蓄電池の回復充電を行う。 The charging control device performs floating charging so as to compensate for the self-discharged amount of the storage battery when no power outage occurs. The floating charging current is, for example, about (5/10,000)C to (1/1000)C (C is the rated capacity of the storage battery), which is very small. In addition, the charge control device performs recovery charging of the storage battery when detecting stop of power failure (corresponding to restoration of power) after detecting power failure.
蓄電池１２の回復充電の条件について説明する。
発明者等は、蓄電池１２を構成する制御弁式鉛蓄電池１２Ａの回復充電の条件を求めるべく、以下の実験を行った。
１セルが２Ｖ、２００Ａｈ（１０時間率容量）の制御弁式鉛蓄電池を製作し、周囲温度２５℃の環境にて、充電電流を０．１Ｃ１０Ａとし満充電となるまで充電し、次いで、放電電流０．１Ｃ１０Ａで終止電圧１．８Ｖまで放電を行い、初期容量を測定した。次に、０．１Ｃ１０Ａの放電電流で５時間放電を行い、充電電流を０．１Ｃ１０Ａとし、２．３Ｖ〜２．４Ｖの定電圧充電時間を表１のように変化させて、充放電を行った。
The conditions for recovery charging of the
The inventors conducted the following experiment in order to find the conditions for recovery charging of the control valve type
A control valve type lead-acid battery with 2 V and 200 Ah (10 hour rate capacity) per cell was manufactured and charged at an ambient temperature of 25° C. until the charging current was 0.1 C 10 A and the battery was fully charged. Discharge was performed at a discharge current of 0.1 C 10 A to a final voltage of 1.8 V, and the initial capacity was measured. Next, the 5 hour discharge at a discharge current of 0.1 C 10 A, the charging current and 0.1 C 10 A, the constant voltage charging time 2.3V~2.4V varied as shown in Table 1, It was charged and discharged.
ここで、充電電圧を値Ｘとした場合、Ｘ＝２．３Ｖ／セル〜２．４Ｖ／セル・・・式（１）としたのは、高い電圧で充電することで、充電時間の短縮が可能となり、充電量も確保し易くなるからである。例えば、放電頻度が高い場合は、満充電状態になる前に放電が開始される可能性があり、そのような運用が続くと、充電不足状態となり、寿命に影響を与える。即ち、高い充電電圧で充電を行い、次の放電に備えることで短寿命を防ぐことが可能となる。なお、充電電圧が２．３Ｖより低い場合、定格容量維持率が低く、２．４Ｖを超える場合、減水率（蓄電池１２の電解液の減液量）が大きくなり短寿命となる。
充放電が終了後、周囲温度２５℃、０．１Ｃ１０Ａ、終止電圧１０．８Ｖまで放電を行い、電池容量を測定した。また、電池作製後の電池質量と３０サイクル後の電池質量を測定して、減水率を求めた。
Here, when the charging voltage is set to the value X, X=2.3 V/cell to 2.4 V/cell... Formula (1) is set because the charging time is shortened by charging at a high voltage. This is because it becomes possible and the amount of charge can be easily secured. For example, when the discharge frequency is high, there is a possibility that the discharge will be started before the full charge state is reached, and if such an operation continues, a shortage state of charge will occur, which will affect the life. That is, it becomes possible to prevent short life by charging at a high charging voltage and preparing for the next discharge. If the charging voltage is lower than 2.3V, the rated capacity maintenance rate is low, and if it exceeds 2.4V, the water reduction rate (reduced amount of the electrolytic solution of the storage battery 12) becomes large and the life becomes short.
After the charging/discharging was completed, the battery capacity was measured by discharging at an ambient temperature of 25° C., 0.1 C 10 A, and a final voltage of 10.8 V. Further, the water mass after the battery was manufactured and the battery mass after 30 cycles were measured to obtain the water reduction rate.
実施例１−９は、３０サイクル後の容量維持率が１００％以上となり、３０サイクル後の減水率が０．８３％以下であった。比較例１−４、６、８、１０、１２は、３０サイクル後の容量維持率が９９％以下となっており、充電不足状態になっていることが分かる。比較例５、７は、定電圧充電時間が３２時間と長くなり、十分に充電されない状態で放電される可能性が高くなる。また、比較例９、１１、１３−１６は、３０サイクル後の減水率が０．８３％を超えてしまう。充電不足状態での運用、及び減水率の増大は、いずれも電池寿命に悪影響を与える。 In Example 1-9, the capacity retention rate after 30 cycles was 100% or more, and the water reduction rate after 30 cycles was 0.83% or less. In Comparative Examples 1-4, 6, 8, 10, and 12, the capacity retention ratio after 30 cycles is 99% or less, and it is understood that the charging is insufficient. In Comparative Examples 5 and 7, the constant voltage charging time was as long as 32 hours, and there is a high possibility that the battery will be discharged in a state where it is not sufficiently charged. Moreover, in Comparative Examples 9, 11, 13-16, the water reduction rate after 30 cycles exceeds 0.83%. Both operation with insufficient charge and increase in water reduction rate adversely affect battery life.
そこで、発明者等は、図２に示すように、実施例１−９及び比較例１−１６について、充電電圧、及び定電圧充電時間（以下、充電時間と言う）をプロットしてグラフを作成し、最適範囲を検討した。図２には、横軸を充電電圧Ｘとし、縦軸を充電時間Ｙとしている。
図２中、符号Ａ１は実施例１を示し、符号Ａ２は実施例２を示し、符号Ａ３は実施例３を示し、符号Ａ４は実施例４を示し、符号Ａ５は実施例５を示し、符号Ａ６は実施例６を示し、符号Ａ６は実施例６を示し、符号Ａ７は実施例７を示し、符号Ａ８は実施例８を示し、符号Ａ９は実施例９を示している。また、図２中、符号Ｂ１〜Ｂ１６は比較例１−１６をそれぞれ示している。
Therefore, as shown in FIG. 2, the inventors plot a charging voltage and a constant voltage charging time (hereinafter, referred to as charging time) for Example 1-9 and Comparative Example 1-16 to create a graph. Then, the optimum range was examined. In FIG. 2, the horizontal axis represents the charging voltage X and the vertical axis represents the charging time Y.
In FIG. 2, reference numeral A1 indicates the first embodiment, reference numeral A2 indicates the second embodiment, reference numeral A3 indicates the third embodiment, reference numeral A4 indicates the fourth embodiment, reference numeral A5 indicates the fifth embodiment, and reference numeral Reference numeral A6 indicates the sixth embodiment, reference numeral A6 indicates the sixth embodiment, reference numeral A7 indicates the seventh embodiment, reference numeral A8 indicates the eighth embodiment, and reference numeral A9 indicates the ninth embodiment. Further, in FIG. 2, reference numerals B1 to B16 indicate Comparative Examples 1-16, respectively.
このグラフに基づき、発明者等は、充電電圧が２．３Ｖ、２．３５Ｖ、２．４Ｖの各々について、充電時間が短い側に位置するＡ１、Ａ４、Ａ７を一次式Ｙ１で近似するとともに、充電時間が長い側に位置するＡ３、Ａ６、Ａ９を一次式Ｙ２で近似した。そして、これら一次式Ｙ１、Ｙ２で囲まれるエリアＡＲ１（図２にハッチングを付して示す）であれば、３０サイクル後の容量維持率が１００％以上であり、定電圧充電時間も長くならず、且つ、３０サイクル後の減水率が０．８３％以下であることを見いだした。 Based on this graph, the inventors approximate A1, A4, and A7 located on the short charging time side with a linear expression Y1 for each of the charging voltages of 2.3V, 2.35V, and 2.4V, and A3, A6, and A9 located on the longer charging time side were approximated by the linear expression Y2. Then, in the area AR1 surrounded by these linear expressions Y1 and Y2 (shown by hatching in FIG. 2), the capacity retention ratio after 30 cycles is 100% or more, and the constant voltage charging time does not become long. It was also found that the water reduction rate after 30 cycles was 0.83% or less.
一次式Ｙ１、Ｙ２については、以下の算出結果が得られた。
Ｙ１＝−１２０Ｘ＋２９６・・・式（２）、
Ｙ２＝−１２０Ｘ＋３０４・・・式（３）
The following calculation results were obtained for the linear expressions Y1 and Y2.
Y1=-120X+296... Formula (2),
Y2=-120X+304... Formula (3)
以上により、充電電圧Ｘ＝２．３Ｖ／セル〜２．４Ｖ／セル・・・式（１）であり、且つ、充電時間Ｙについては、−１２０Ｘ＋２９６≦Ｙ≦−１２０Ｘ＋３０４・・・式（４）であれば、減水率を抑えて、充電不足にならない状態にすることが可能であった。 As described above, the charging voltage X=2.3 V/cell to 2.4 V/cell is the formula (1), and the charging time Y is −120X+296≦Y≦−120X+304 (formula (4)). In that case, it was possible to suppress the water reduction rate and prevent the battery from becoming insufficiently charged.
次に、充電制御装置１５の停電に関する動作を説明する。
図３は停電に関する動作を示すフローチャートである。なお、本実施形態の充電制御装置１５は、不図示の内蔵バッテリーを搭載することによって、又は、蓄電池１２の電力を利用することによって、停電時でも動作可能である。
充電制御装置１５は、停電を検出しない場合（ステップＳ１；ＮＯ）、浮動充電を行う（ステップＳ２）。これにより、蓄電池１２は満充電状態に維持される。
Next, the operation regarding the power failure of the charging
FIG. 3 is a flowchart showing the operation related to a power failure. The charging
When the power failure is not detected (step S1; NO), the charging
一方、停電を検出した場合（ステップＳ１；ＹＥＳ）、充電制御装置１５は、停電が終了するまで（つまり、復電が行われるまで）待機する（ステップＳ３；ＮＯ）。なお、停電の場合、浮動充電は自動的に停止される。なお、充電制御装置１５が浮動充電を強制停止させる制御を行ってもよい。
On the other hand, when the power failure is detected (step S1; YES), the charging
停電が終了すると（ステップＳ３；ＹＥＳ）、充電制御装置１５は、回復充電の条件を設定する（ステップＳ４）。この場合、充電制御装置１５は、上述した式（１）を満たす充電電圧Ｘ、及び式（４）を満たす充電時間Ｙを設定する。続いて、充電制御装置１５は、設定した充電電圧Ｘ、充電時間Ｙで定電圧充電を行うことにより、回復充電を行う（ステップＳ５）。回復充電が終了すると（ステップＳ６；ＹＥＳ）、充電制御装置１５は、浮動充電に切り替える。以上が停電に関する動作である。
When the power failure ends (step S3; YES), the charging
本実施形態の回復充電によれば、減水率を抑えて、充電不足にならない状態まで充電できるので、蓄電池１２の寿命への影響を抑えることができる。しかも、一次式からなる式（１）及び式（４）によって回復充電の条件を算出するので、条件の算出が容易である。これによって、バックアップ用途の制御弁式鉛蓄電池からなる蓄電池１２を、簡易な制御で寿命低下を抑制可能になる。
According to the recovery charging of the present embodiment, it is possible to suppress the water reduction rate and to charge until the state where the charging is not insufficient, so that it is possible to suppress the influence on the life of the
したがって、例えば、停電が計画的に行われる事態（計画停電）が生じ、想定よりも停電回数が多くなったとしても、蓄電池１２の当初の期待寿命を満足させ易くなる。また、電池システム１０の信頼性を要求されるために定期的に放電を行い、蓄電池１２の状態をチェックする運用となったとしても、蓄電池１２の当初の期待寿命を満足させ易くなる。
Therefore, for example, even if a power outage occurs intentionally (planned power outage) and the number of power outages is greater than expected, it is easy to satisfy the initial expected life of the
上記式（１）及び式（４）によれば、充電電圧Ｘ＝２．３Ｖ／セル〜２．４Ｖ／セルとしたときに、充電時間Ｙは、８時間〜２８時間の範囲で任意に設定することが可能である。例えば、計画停電が行われる事態が判明した場合、回復充電の充電時間Ｙを、計画停電の時間間隔（例えば２日）よりも短い時間に設定することが好ましい。これによれば、計画停電の合間に回復充電を終えることが可能になり、十分に充電されない状態で放電される事態を回避できる。 According to the formulas (1) and (4), the charging time Y is arbitrarily set within the range of 8 hours to 28 hours when the charging voltage X is 2.3 V/cell to 2.4 V/cell. It is possible to For example, when it is determined that a planned power outage will occur, it is preferable to set the charging time Y for recovery charging to a time shorter than the time interval (for example, 2 days) between planned power outages. According to this, it becomes possible to finish the recovery charging between planned blackouts, and it is possible to avoid a situation in which the battery is discharged in a state where it is not sufficiently charged.
本発明は上述の実施形態に限定されるものではなく、本発明の技術思想に基づいて各種の変形、及び変更が可能である。 The present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention.
