Description
本発明は蓄電池のインピーダンス測定方法及びその測定治具に関するもので、特に、交流インピーダンス測定方法を用いて蓄電池の内部抵抗を計測するのに適したインピーダンス測定方法並びにその測定治具に関するものである。 The present invention relates to a storage battery impedance measurement method and a measurement jig thereof, and more particularly to an impedance measurement method suitable for measuring the internal resistance of a storage battery using an alternating current impedance measurement method and a measurement jig thereof.
蓄電池の内部抵抗を測定する際にはプラス（＋）側電線とマイナス（−）側電線とを撚ることで誘導結合の結合度を小さくし、遮蔽効果を得ている。
しかしながら、蓄電池に計測電線を接続するには、蓄電池の＋−端子が左右に（または前後に）離れた位置に設置されているために、計測電線の端末部分の撚りをある程度解いて左右の端子に接続している（特許文献１）。
However, in order to connect the measuring wire to the storage battery, the + and-terminals of the storage battery are installed at positions left and right (or back and forth). (Patent Document 1).
測定電線の撚りを解き、左右の端子に接続する際に、例えば図７に示すように蓄電池１に測定電流を印加する印加線２と蓄電池の電圧を計測する計測線３とが交差すると、測定電流が作り出す磁束が計測線３に結合して測定電流に対し９０°位相のずれた誘導電圧を計測線３に誘起し、測定結果に誤差を発生させることがある。
前記測定では印加線２と計測線３との交差が測定結果に影響する事例について説明したが、図７に示すように印加線２と計測線３とがある長さ以上平行に配置された場合にも電磁誘導により測定結果に影響がでる場合がある。
When the measurement wire is untwisted and connected to the left and right terminals, for example, as shown in FIG. 7, if the application line 2 for applying the measurement current to the storage battery 1 and the measurement line 3 for measuring the storage battery voltage intersect, The magnetic flux generated by the current may be coupled to the measurement line 3 to induce an induced voltage 90 ° out of phase with respect to the measurement current in the measurement line 3 and cause an error in the measurement result.
In the measurement, the case where the intersection of the application line 2 and the measurement line 3 affects the measurement result has been described. However, when the application line 2 and the measurement line 3 are arranged in parallel for a certain length or more as shown in FIG. In addition, the measurement results may be affected by electromagnetic induction.
本発明は交流電流により蓄電池のインピーダンス測定を誘導電圧、電磁誘導の影響を受けずに正確に測定できる蓄電池のインピーダンス測定方法を提供し、また、蓄電池のインピーダンスを測定する際に使用し、蓄電池のインピーダンスを正確に測定できる測定治具を提供することを目的とするものである。 The present invention provides a method for measuring the impedance of a storage battery that can accurately measure the impedance of the storage battery by an alternating current without being influenced by the induced voltage and electromagnetic induction, and is used when measuring the impedance of the storage battery. An object of the present invention is to provide a measuring jig capable of accurately measuring impedance.

前記−側絶縁閉塞体に蓄電池の−端子に接続する−側計測線と−側印加線とが反対回りとなるように取り付けて、前記計測線と印加線とが平行に配置される部分の距離が、＋端子と−端子との間の距離の１／２乃至３／５となるようにして、
蓄電池のインピーダンスを計測する。

本発明を図示する実施形態につき説明する。
図１は本発明の第１の実施形態で、図１に示す蓄電池１のインピーダンス測定方法は、蓄電池１のインピーダンスを測定するための測定電流を流す電流印加線２と、電池の電圧を検出する電圧計測線３とを蓄電池の端子に接続して交流により蓄電池のインピーダンスを測定する方法に関するものである。
The present invention will be described with reference to the illustrated embodiments.
FIG. 1 shows a first embodiment of the present invention. The method for measuring the impedance of the storage battery 1 shown in FIG. 1 detects a current application line 2 for passing a measurement current for measuring the impedance of the storage battery 1 and the voltage of the battery. The present invention relates to a method of measuring the impedance of the storage battery by alternating current by connecting the voltage measuring line 3 to the terminal of the storage battery.
本実施形態において、電流印加線２は２本の素線が撚り合わされた電線でその端末部分は蓄電池１の＋端子１１と−端子１２との距離間の長さより長く撚りを解いて２本の素線に分離し、その一方の端末を蓄電池１の＋端子１１に、他方の端末を−端子１２にそれぞれ接続し、蓄電池のインピーダンス測定用の交流電流を通電する。撚りを解かれた２本の素線２１、２２は図１に示すように蓄電池１の端子が設けられている表面の縦の辺１４、１５に沿って配線され、絶縁テープ（例えば絶縁接着テープ）４で蓄電池１の表面に固定されている。 In the present embodiment, the current application wire 2 is an electric wire in which two strands are twisted together, and its terminal portion is untwisted longer than the distance between the distance between the positive terminal 11 and the negative terminal 12 of the storage battery 1 and The wires are separated, one terminal is connected to the + terminal 11 of the storage battery 1 and the other terminal is connected to the − terminal 12, and an alternating current for measuring the impedance of the storage battery is energized. As shown in FIG. 1, the untwisted two strands 21 and 22 are wired along the vertical sides 14 and 15 of the surface on which the terminals of the storage battery 1 are provided, and an insulating tape (for example, an insulating adhesive tape) 4) fixed to the surface of the storage battery 1 at 4.
インピーダンス計測用の電圧計測線３は２本の素線が撚り合わされた電線でその端末部分は蓄電池１の＋端子１１と−端子１２との距離の長さの半分にほぼ等しい長さだけ撚りを解いて２本の素線に分離し、一方の端末は蓄電池１の＋端子１１に、他方の端末は−端子１２にそれぞれ接続して蓄電池のインピーダンスを測定する。撚りを解かれた２本の素線３１、３２は図１に示すように蓄電池１の表面の横の辺１６に沿って左右に配置され、絶縁テープ（例えば絶縁接着テープ）４で蓄電池表面に固定されている。そして各端子において、電流印加線の素線２１、２２と電圧計測線の素線３１、３２はそれぞれ９０度の角度をもって位置している。
なお、絶縁テープ４はインピーダンス測定中に蓄電池１の温度が上がり、絶縁テープ４を熱劣化させる恐れがあるので、耐熱性のものを使用すると良い。
上述したように配線が終了した後、図示しない測定電流源から測定交流電流を蓄電池１に印加し、印加電流により発生するインピーダンスを計測線３に接続の図示しない電圧計で計測する。
The voltage measurement line 3 for impedance measurement is an electric wire in which two strands are twisted together, and the end portion of the voltage measurement line 3 is twisted by a length approximately equal to half the distance between the + terminal 11 and the − terminal 12 of the storage battery 1. It is unraveled and separated into two wires, and one terminal is connected to the + terminal 11 of the storage battery 1 and the other terminal is connected to the − terminal 12 to measure the impedance of the storage battery. As shown in FIG. 1, the two untwisted strands 31 and 32 are arranged on the left and right sides along the side 16 on the surface of the storage battery 1, and the insulating tape (for example, insulating adhesive tape) 4 is used to It is fixed. At each terminal, the strands 21 and 22 of the current application line and the strands 31 and 32 of the voltage measurement line are positioned at an angle of 90 degrees.
In addition, since the temperature of the storage battery 1 rises during the impedance measurement and the insulating tape 4 may be thermally deteriorated, it is preferable to use a heat-resistant tape.
After wiring is completed as described above, a measurement alternating current is applied to the storage battery 1 from a measurement current source (not shown), and an impedance generated by the applied current is measured with a voltmeter (not shown) connected to the measurement line 3.
図１に示すように本実施形態では印加線２の素線２１と計測線３の素線３１とが平行に配置される部分がある。この平行に配置される部分の距離が近過ぎると電磁誘導の影響が発生する。図４は印加線２の素線２１が蓄電池１の辺から離れて配置され計測線３の素線３１とが平行に配置される部分が近接している例である。このように、印加線２の素線２１と計測線３の素線３１とが平行に配置される部分の距離が近過ぎると電磁誘導の影響が出てインピーダンスの測定結果に誤差が発生する。本実施形態では前記計測線と印加線とが平行に配置される部分の距離を、＋端子１１と−端子１２との間の距離の１／２以上、好ましくは１／２乃至３／５とした。計測線と印加線とが平行に配置される部分の距離を、＋端子１１と−端子１２との間の距離の１／２以上とすることで印加線からの電磁誘導による測定値への影響がなくなり、正確な測定値を得ることができる。 As shown in FIG. 1, in this embodiment, there is a portion where the strand 21 of the application line 2 and the strand 31 of the measurement line 3 are arranged in parallel. If the distance between the parallel parts is too short, the influence of electromagnetic induction occurs. FIG. 4 is an example in which the strand 21 of the application line 2 is arranged away from the side of the storage battery 1 and the portion where the strand 31 of the measurement line 3 is arranged in parallel is close. In this way, if the distance between the portions where the strand 21 of the application line 2 and the strand 31 of the measurement line 3 are arranged in parallel is too close, the influence of electromagnetic induction appears and an error occurs in the impedance measurement result. In this embodiment, the distance between the measurement line and the application line arranged in parallel is ½ or more of the distance between the + terminal 11 and the − terminal 12, preferably 1/2 to 3/5. did. By setting the distance of the portion where the measurement line and the application line are arranged in parallel to be ½ or more of the distance between the + terminal 11 and the − terminal 12, the influence on the measurement value due to electromagnetic induction from the application line Therefore, accurate measurement values can be obtained.
本実施形態においては、蓄電池１の端子を配置した表面で、蓄電池１の＋端子１１に接続する＋側印加線の素線２１と＋側計測線の素線３１とを蓄電池の異なる辺に沿って配置し、蓄電池の−端子１２に接続する−側印加線の素線２２と−側計測線の素線３２とを蓄電池１の異なる辺に沿って配置することで、印加線２の素線２１と計測線３の素線３１が、印加線の素線２２と計測線の素線３２とがそれぞれ交差することなく、かつ平行となる部分の距離を＋端子と−端子との間の距離の１／２以上として蓄電池のインピーダンスを計測する。このため、計測線３と印加線２との間で誘導電圧、誘導電圧による誤差が発生せず、より正確にインピーダンスの測定ができる。 In the present embodiment, on the surface on which the terminal of the storage battery 1 is arranged, the strand 21 of the + side application line and the strand 31 of the + side measurement line connected to the + terminal 11 of the storage battery 1 are along different sides of the storage battery. By arranging the wire 22 of the negative side application line and the strand 32 of the negative side measurement line connected to the negative terminal 12 of the storage battery along different sides of the storage battery 1, 21 and the element wire 31 of the measurement line 3 are the distance between the + terminal and the − terminal, and the distance between the application wire element 22 and the measurement element element wire 32 does not intersect with each other and is parallel. The impedance of the storage battery is measured as 1/2 or more. For this reason, an error due to the induced voltage and the induced voltage does not occur between the measurement line 3 and the application line 2, and the impedance can be measured more accurately.
図２は本発明の第２の実施形態で、図１と共通する部分には同一の符号を付している。
図２に示す実施形態では、蓄電池１の表面に絶縁閉塞体５、６が設けられている。絶縁閉塞体５には＋端子１１に接続する印加線２の＋側素線２１と計測線３の＋側素線３１とが逆方向向きに巻き付けられて配線され、両者の端末は＋端子１１に接続されている。
一方絶縁閉塞体６には−端子１２に接続する印加線２の−側素線２２と計測線３の−側素線３２とが逆方向向きに巻き付けられて配線され、両者の端末は−端子１２に接続されている。
FIG. 2 shows a second embodiment of the present invention, and the same reference numerals are given to the parts common to FIG.
In the embodiment shown in FIG. 2, insulating closures 5 and 6 are provided on the surface of the storage battery 1. The insulation block 5 is wired with the + side strand 21 of the application line 2 connected to the + terminal 11 and the + side strand 31 of the measurement line 3 wound in opposite directions, and both terminals are connected to the + terminal 11. It is connected to the.
On the other hand, a negative side wire 22 of the application wire 2 connected to the negative terminal 12 and a negative side wire 32 of the measuring wire 3 are wound in the opposite direction on the insulating closing body 6 and wired. 12 is connected.
絶縁閉塞体５、６は図２に示すように蓄電池１の表面に設置するか、その近傍に配置する。絶縁閉塞体５、６の材質は蓄電池１のインピーダンス測定中に酸性ガスが発生する恐れがあるため、耐酸性で前記したように耐熱性の材用で作成することが好ましい。
印加線２を絶縁閉塞体５、６に巻き付けるには、印加線２の端末部分の撚りを蓄電池の＋端子１１と−端子１２との距離より長めに解いて２本の素線に分離し、一方の素線を絶縁閉塞体５に時計回りに、他方の素線を絶縁閉塞体６に反時計方向に巻き付ける。
計測線３を絶縁閉塞体５、６に巻き付けるには、計測線３の端末部分の撚りを蓄電池の＋端子１１と−端子１２との距離の長さの半分よりやや長く解いて２本の素線に分離し、一方の素線を絶縁閉塞体５に反時計回りに、他方の素線を絶縁閉塞体６に時計方向に巻き付ける。
The insulation blockers 5 and 6 are installed on the surface of the storage battery 1 as shown in FIG. Since the material of the insulating plugs 5 and 6 may generate acid gas during the impedance measurement of the storage battery 1, it is preferably made of an acid resistant and heat resistant material as described above.
In order to wrap the application wire 2 around the insulation blockers 5 and 6, the twist of the terminal portion of the application wire 2 is unraveled longer than the distance between the + terminal 11 and the −terminal 12 of the storage battery and separated into two strands, One strand is wound clockwise around the insulating closure 5 and the other strand is wound around the insulation closure 6 in the counterclockwise direction.
In order to wrap the measuring wire 3 around the insulation blockers 5 and 6, the twist of the terminal portion of the measuring wire 3 is unraveled slightly longer than half of the length of the distance between the positive terminal 11 and the negative terminal 12 of the storage battery. The wires are separated, and one strand is wound around the insulating closure 5 in the counterclockwise direction, and the other strand is wound around the insulation closure 6 in the clockwise direction.
本実施形態２では絶縁閉塞体５、６は円周が蓄電池１の辺に到達する程度の大きな直径を有する円形で、計測線３が円周の１／３〜１／４程度、印加線２が１／２程度の長さで巻き付けられ、線の端末はそれぞれの端子に接続されている。なお、絶縁閉塞体５、６に素線２１、２２、３１，３２をそれぞれ巻き付ける際には巻き付けた状態で左右の形状がほぼ対称となるように絡めていくと測定結果はより正確になる。
本実施形態２においては、絶縁閉塞体５，６に印加線２と計測線３とを巻き付けることで両線が交差、あるいは平行になるのを防止しているが、一部で両者が平行になる場合がある。このような時に両者の距離が近接していると印加線２の電圧による電磁誘導が計測線３に影響するので、平行となる（恐れのある）部分の距離を＋端子１１と−端子１２との間の距離の１／２以上となるように設計する。このように設計して蓄電池１のインピーダンスを計測することにより、計測線３と印加線２との間で電磁誘導、誘導電圧が発生せず、正確にインピーダンスの測定ができる。
In the second embodiment, the insulation blockers 5 and 6 are circular having a large diameter such that the circumference reaches the side of the storage battery 1, and the measurement line 3 is about 1/3 to 1/4 of the circumference. Is wound with a length of about ½, and the ends of the lines are connected to the respective terminals. In addition, when winding the strands 21, 22, 31, and 32 on the insulating blockers 5 and 6, respectively, the measurement results become more accurate if they are entangled so that the left and right shapes are almost symmetrical.
In Embodiment 2, the application line 2 and the measurement line 3 are wound around the insulation blockers 5 and 6 to prevent the lines from intersecting or paralleling. There is a case. In such a case, if the distance between the two is close, electromagnetic induction due to the voltage of the applied line 2 affects the measurement line 3, so the distance between the parallel (possibly feared) portions is set to + terminal 11 and −terminal 12. It is designed to be at least 1/2 of the distance between. By designing in this way and measuring the impedance of the storage battery 1, no electromagnetic induction or induced voltage is generated between the measurement line 3 and the application line 2, and the impedance can be measured accurately.
図３は本発明の第３の実施形態で、図２との相違点は絶縁閉塞体５、６が蓄電池１の辺に沿う大きな四角形である点のみである。絶縁閉塞体を四角形にすることにより、計測線３の撚りを解く長さを端子間の長さよりやや長く解くだけですみ、電磁誘導、誘導電圧の影響を図２に示す実施形態より受け難くなる。 FIG. 3 shows a third embodiment of the present invention. The only difference from FIG. 2 is that the insulating closures 5 and 6 are large squares along the side of the storage battery 1. By making the insulation blocker square, it is only necessary to unwind the measuring wire 3 to be slightly longer than the length between the terminals, and the influence of electromagnetic induction and induced voltage is less susceptible to the embodiment shown in FIG. .
本実施形態３では図１に示す第１実施形態と同様、前記印加線２と計測線３とが平行に配置される部分が出てくるが、この距離を、＋端子１１と−端子１２との間の距離の１／２以上、好ましくは１／２乃至３／５程度離すことで印加線２からの誘導電圧による測定値への影響がなくなり、正確な測定値を得ることができる。 In the third embodiment, as in the first embodiment shown in FIG. 1, there is a portion where the application line 2 and the measurement line 3 are arranged in parallel, and this distance is set between the + terminal 11 and the − terminal 12. When the distance between them is at least 1/2, preferably about 1/2 to 3/5, the influence of the induced voltage from the applied line 2 on the measurement value is eliminated, and an accurate measurement value can be obtained.
図５、６は本実施形態２、３に対する比較例を示し、図５では本実施形態２よりも絶縁閉塞体５，６の直径が短く円周が蓄電池１の辺から離れ、印加線２と計測線３とが平行となる部分の距離が、＋端子１１と−端子１２との間の距離の１／２以下となっている例であり、図６は本実施形態３よりも四角形が小さく絶縁閉塞体５，６の印加線２と計測線３とが平行となる部分の間隔が短く、計測線と印加線とが平行となる部分の間隔が、＋端子１１と−端子１２との間の距離の１／２以下となっている例であり、共にインピーダンスの測定結果は誤差を含む結果となった。 5 and 6 show comparative examples for the second and third embodiments. In FIG. 5, the diameters of the insulating closures 5 and 6 are shorter than those of the second embodiment, and the circumference is far from the side of the storage battery 1. This is an example in which the distance of the part parallel to the measurement line 3 is ½ or less of the distance between the + terminal 11 and the − terminal 12, and FIG. 6 is smaller in the quadrangle than the third embodiment. The interval between the portions where the application line 2 and the measurement line 3 of the insulating blockers 5 and 6 are parallel is short, and the interval between the portion where the measurement line and the application line are parallel is between the + terminal 11 and the − terminal 12. In this example, the impedance measurement result includes an error.
なお、本実施形態２、３における、絶縁閉塞体５，６に印加線２と計測線３とを取付けた状態が本発明のインピーダンス測定用治具の実施形態に対応する。 In the second and third embodiments, the state in which the application line 2 and the measurement line 3 are attached to the insulating plugs 5 and 6 corresponds to the embodiment of the impedance measurement jig of the present invention.
