法に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for judging deterioration of a lead acid battery for an automobile, for judging the degree of deterioration of the lead acid battery for an automobile.

きている。2. Description of the Related Art In recent years, the number of electrical components for automobiles has increased, and the load on automobile lead-acid batteries (hereinafter referred to as batteries) has increased.

定が広く行われている。しかし、比重が高くても始動が
できないもの、低くても少し充電すれば始動できるもの
等、寿命品か、回復可能品かの判定が困難であった。Generally, as a method of judging the degree of deterioration of a battery, the specific gravity of dilute sulfuric acid as an electrolytic solution and the battery voltage are widely measured. However, it is difficult to determine whether the product has a long life or is recoverable, such as one that cannot be started even if the specific gravity is high, or one that can be started even if it is low even if it is charged a little.

There is a method of determining the deterioration of the battery, which is obtained by measuring the above values and using a predetermined standard or an arithmetic expression.

る。For example, there is a battery deterioration determination method disclosed in Japanese Patent Laid-Open No. 5-322999, which determines whether or not the battery is deteriorated based on the battery voltage when the engine is stopped and the battery voltage when the engine is started. Specifically, it detects whether the battery capacity is low or the battery is insufficiently charged, and in the former case, the battery is replaced, and in the latter case, the battery is supplementally charged and the vehicle charging system is corrected. Further, when the battery is deteriorated, a function of predicting the time when the engine cannot be started is added from the data of the battery voltage at the time of starting the engine.

始動時の電池電圧が必要である。つまり、チェックの際

さらに電池電圧は温度にも影響される。従来技術が提示
している寿命予測をするためには、車両固有のデータが
予め必要で、汎用性に乏しく、電圧の温度補正をしなけ
れば誤った予測をする可能性がある。In such a battery deterioration determination method, the battery voltage when the engine is stopped and the battery voltage when the engine is started are required. In other words, it is essential to install the vehicle in the check. However, the vehicle charging circuit and starting circuit differ depending on the manufacturer and model,
Furthermore, the battery voltage is also affected by temperature. Vehicle-specific data is required in advance to predict the service life proposed by the prior art, is not versatile, and may lead to erroneous prediction unless voltage temperature correction is performed.
【０００７】また、電圧情報だけでは、劣化したのが正
極か負極かわからず、電圧が正常でもどちらかの極が寿
命間近の場合もあるため、交換の判断を、見誤る危険性
がある。Further, since it is not known whether the deterioration is the positive electrode or the negative electrode based on only the voltage information, and there is a case where either of the electrodes is near the end of its life even if the voltage is normal, there is a risk of mistaking the replacement judgment.
【０００８】本発明の目的は、自動車用鉛蓄電池が車両

劣化判定方法を提供することにある。An object of the present invention is to provide a method for determining deterioration of a lead acid battery for an automobile, which can determine whether the lead acid battery for an automobile is not mounted on a vehicle and whether the battery capacity is decreased or the battery is insufficiently charged. Especially.

パルスで充電し、充電電流に応じた電池電圧の変化を測
定し、新品の自動車用鉛蓄電池での測定値と比較するこ
とで前記自動車用鉛蓄電池の劣化度合いを判定する。A method for determining deterioration of a lead-acid battery for an automobile according to the present invention is a method of charging a lead-acid battery for an automobile with a direct current pulse and measuring a change in battery voltage according to a charging current to obtain a new battery. The degree of deterioration of the lead acid battery for an automobile is determined by comparing the measured value with the lead acid battery for an automobile.
【００１０】この場合、上記劣化度合いの判定時には、
参照電極を用いて単極電位を測定し、劣化極を判定する
ことが好ましい。In this case, when determining the degree of deterioration,
It is preferable to measure the unipolar potential using a reference electrode and determine the deterioration pole.
【００１１】また、上記参照電極は、自動車用鉛蓄電池
の電解液である希硫酸に対する溶解度が低く、該自動車
用鉛蓄電池への電位変動の影響が少ないものであること
が好ましい。Further, it is preferable that the reference electrode has low solubility in dilute sulfuric acid, which is an electrolytic solution of a lead acid battery for automobiles, and has little influence of potential fluctuation on the lead acid battery for automobiles.

の３種類の変化を定量的に捉えることで、電池内部の状
態を把握できる。By the way, in a lead-acid battery for an automobile, a chemical reaction occurs inside when a DC voltage or current is applied from the outside,
A potential change occurs between the positive electrode and the negative electrode (hereinafter referred to as polarization). The battery voltage is the difference between the positive electrode potential and the negative electrode potential, and the difference between these positive electrode potential and the negative electrode potential (battery voltage)
By quantitatively capturing the three types of changes, the internal state of the battery can be grasped.

流すことから自動車用鉛蓄電池への負担を最小限に抑え
るためと、短時間で判定するためである。Specifically, a lead-acid battery for automobiles is charged with a direct current pulse, variations in the battery voltage and the unipolar potential depending on the charging current are detected, and these are plotted against the corresponding current value. Since this is a charging reaction, the battery voltage rises,
The positive electrode potential is polarized in the positive direction, and the negative electrode potential is polarized in the negative direction. The reason why the direct current is applied as a pulse is to minimize the burden on the lead acid battery for automobiles because a large current is passed, and to determine in a short time.

応にまわらないためである。また、電池の劣化が進行し
すぎると、内部抵抗が上昇し、外部からの印加が困難に
なる現象も生ずる。When the battery is fully charged, the applied power is used in the polarization direction, and the slope of the polarization curve becomes large. On the contrary, when the charge is insufficient, the slope of the polarization curve is hardly seen. This is because the applied power is consumed in the charging reaction and does not go into the polarization reaction. Further, when the deterioration of the battery progresses too much, the internal resistance rises, and the phenomenon that the application from the outside becomes difficult occurs.

ある。Such a method of judging deterioration of a lead acid battery for a vehicle is a method of judging whether the lead acid battery is replaced or a supplementary charge, and it is in a state where the lead acid battery for a vehicle is not mounted on the vehicle, that is, the vehicle. It is possible to perform measurement in a temperature control room without depending on an electric circuit, and to solve the problems in the conventional method.

継続使用に注意を喚起することができる。Further, when determining the degree of deterioration, the unipolar potential is measured using the reference electrode and the deterioration pole is specified.
It is possible to call attention to continuous use.

且つ電位変動の影響を少なくすることができる。If a reference electrode having a low solubility in dilute sulfuric acid, which is an electrolytic solution of a lead acid battery for automobiles, and a small influence of potential fluctuation is used, it is difficult to dissolve in dilute sulfuric acid.
In addition, the influence of potential fluctuation can be reduced.

A Cd reference electrode was used for measuring the unipolar potential. This Cd reference electrode 1
2, a cylindrical metal Cd2 is inserted into an acid-resistant insulating container 3 and several holes 4 are provided in the container 3 so that it can come into contact with dilute sulfuric acid. Cylindrical metal Cd2
One end of CdSO4 is generated by immersing it in the same specific gravity as the dilute sulfuric acid of the lead acid battery for automobiles to be measured. The other end of the metal Cd2 is soldered to the lead wire 5 and pulled out to the outside. This Cd / CdSO4 reference electrode 1 has a low solubility in dilute sulfuric acid and has a characteristic that it has little effect on potential fluctuations in a lead acid battery for automobiles.

A voltmeter 12 is connected to the lead wire 5 and the negative electrode terminal 6b through a negative electrode potential measuring wire 11 to measure the negative electrode potential V3.

Keep the temperature at ℃ and charge with the charging pulse pattern shown in Fig. 1,
The battery voltage, positive electrode potential and negative electrode potential are measured. FIG. 4 shows the changes over time in the current and potential during pulse charging. There is almost no change in the voltage when the charging current is 1A, but 10A, 20
It can be seen that the voltage increases with each increase in A and 50 A, and polarization progresses.

Charge with the charging pulse pattern in the same manner as above, and set each current value to 1
FIG. 6 shows a current-potential diagram in which the voltage and the potential at 5 seconds at A, 10A, 20A, and 50A are plotted. Compared to FIG. 5, in FIG. 6, the slope of voltage and current fluctuations at 10 A or less is small. This suggests that the charging reaction is occurring in this area, and can be said to compensate for the insufficient charging. In the region of 10 A or more, the charging reaction cannot catch up due to the large current, the polarization has priority, and the same slope as in FIG. 5 is shown. Further, in FIG. 6, the positive electrode potential is lower and the negative electrode potential is higher than in FIG. This indicates that the internal reaction material (active material) is deteriorated. In FIG. 6, since the rate of decrease of the positive electrode is large, it is expected that the positive electrode will deteriorate and reach the end of its life. By accumulating such data, it can be used as a countermeasure for improving the deterioration pole.
【００２７】この自動車用鉛蓄電池は、補充電によって

FIG. 7 shows a current-potential diagram in which the voltage and potential at 5 seconds at A, 10A, 20A, and 50A are plotted. In this test, the battery voltage reached 30 V at a charge of 1 A, and the upper limit of the power supply device was applied, so no current flowed. The AC internal resistance of the battery B used in the actual vehicle is 8 to 10
The above phenomenon occurred because it was 10 times. Since the deterioration of the active material is progressing in such a lead-acid battery for automobiles, recovery by supplementary charging is difficult, and it is judged that early replacement is necessary.

Further, although metal Cd / CdSO4 was used as the reference electrode 1, as long as it has the characteristics that the solubility in sulfuric acid is low and the influence of potential fluctuation on the lead acid battery for automobiles is small, the same effect can be obtained. can get.
