　計測側通信部９６が出力する信号には、蓄電装置２２の動作を指示するコマンドが含まれる。このコマンドには、一例として、断続部４８を制御して蓄電デバイス２０の負極と負極被接続部４４とを通電状態とする通電コマンド、及び蓄電デバイス２０の負極と負極被接続部４４とを非通電状態とする非通電コマンドが含まれる。 The signal output by the measurement-side communication unit 96 includes a command for instructing the operation of the power storage device 22 . Examples of this command include an energization command that controls the intermittent unit 48 to bring the negative electrode of the power storage device 20 and the negative electrode connected portion 44 into an energized state, and a power supply command that causes the negative electrode of the power storage device 20 and the negative electrode connected portion 44 to become non-conductive. It includes a de-energization command to turn on the power.
　計測側通信部９６が蓄電装置２２へ通電コマンドを出力すると、蓄電装置２２の各被接続部４０、４４には蓄電デバイス２０の出力電圧が印加される。これにより、各被接続部４０、４４を介して蓄電装置２２の蓄電デバイス２０と外部との電気の遣り取りが可能となる。 When the measurement-side communication unit 96 outputs an energization command to the power storage device 22 , the output voltage of the power storage device 20 is applied to the connected portions 40 and 44 of the power storage device 22 . As a result, electricity can be exchanged between the power storage device 20 of the power storage device 22 and the outside via the connected portions 40 and 44 .
　計測側通信部９６が蓄電装置２２へ非通電コマンドを出力すると、蓄電装置２２の各被接続部４０、４４と蓄電デバイス２０との通電が遮断される。これにより、蓄電装置２２の蓄電デバイス２０と外部との電気の遣り取りが不能となる。 When the measurement-side communication unit 96 outputs a de-energization command to the power storage device 22, the power between the connected portions 40 and 44 of the power storage device 22 and the power storage device 20 is cut off. As a result, exchange of electricity between the power storage device 20 of the power storage device 22 and the outside becomes impossible.
　（計測器の測定部）
　測定部９０は、蓄電装置２２の各被接続部４０、４４に接続され、蓄電デバイス２０の状態を測定する。 (Measuring part of measuring instrument)
The measurement unit 90 is connected to the connected portions 40 and 44 of the power storage device 22 and measures the state of the power storage device 20 .
　測定部９０は、蓄電デバイス２０の電圧を測定する電圧測定部１００と、蓄電デバイス２０に流れる電流を測定する電流測定部１０２とを有する。測定部９０は、電圧測定部１００で測定した電圧と電流測定部１０２で測定した電流とに基づいて蓄電デバイス２０のインピーダンスを演算して蓄電デバイス２０の状態を測定する。演算するインピーダンスには、交流インピーダンスが含まれる。 The measuring section 90 has a voltage measuring section 100 that measures the voltage of the power storage device 20 and a current measuring section 102 that measures the current flowing through the power storage device 20 . Measuring section 90 calculates the impedance of power storage device 20 based on the voltage measured by voltage measuring section 100 and the current measured by current measuring section 102 to measure the state of power storage device 20 . The calculated impedance includes AC impedance.
　電流測定部１０２は信号発生部１０４を備える。信号発生部１０４で発生した発生信号は蓄電デバイス２０に印加される。 The current measuring section 102 includes a signal generating section 104 . A signal generated by the signal generator 104 is applied to the electricity storage device 20 .
　電流測定部１０２は、信号発生部１０４の発生信号を蓄電装置２２の蓄電デバイス２０に流した状態で蓄電デバイス２０に流れる電流を測定信号として測定する。また、電流測定部１０２は、蓄電デバイス２０から流れる電流を測定信号として測定する。 The current measurement unit 102 measures the current flowing through the power storage device 20 of the power storage device 22 as a measurement signal while the signal generated by the signal generation unit 104 is passed through the power storage device 20 of the power storage device 22 . Also, the current measurement unit 102 measures the current flowing from the power storage device 20 as a measurement signal.
　蓄電デバイス２０に流す電流及び蓄電デバイス２０から流れる電流は、５Ａ未満である。蓄電デバイス２０に流す電流及び蓄電デバイス２０から流れる電流は、蓄電デバイス２０の容量によって変更される。 The current flowing to and from the power storage device 20 is less than 5A. The current flowing to and from the power storage device 20 is changed by the capacity of the power storage device 20 .
　蓄電デバイス２０の容量を得る方法としては、一例として、計測装置２４と蓄電装置２２との間で通信を行うことによって得る方法が挙げられる。 One example of a method for obtaining the capacity of the power storage device 20 is to obtain the capacity by communicating between the measuring device 24 and the power storage device 22 .
　具体的に説明すると、蓄電デバイス２０に流す電流及び蓄電デバイス２０から流れる電流は、０．０５Ｃ未満である。Ｃは蓄電デバイス２０の容量を示し、一例として、蓄電デバイス２０の容量１００Ａｈの場合、電流は、０．０５×１００＝５Ａとなる。 Specifically, the current flowing to and from the electricity storage device 20 is less than 0.05C. C indicates the capacity of the electricity storage device 20. As an example, when the capacity of the electricity storage device 20 is 100 Ah, the current is 0.05×100=5A.
　蓄電デバイス２０に流れる電流は、小さいほど蓄電デバイス２０に与える影響は少ない。また、蓄電デバイス２０に流れる電流は、小さいほど蓄電デバイス２０の状態が変化しない。このため、計測装置２４は、蓄電デバイス２０に流れる電流が小さいほど安定した測定結果を得ることができる。 The smaller the current flowing through the electricity storage device 20, the less the impact on the electricity storage device 20. Also, the smaller the current flowing through the electricity storage device 20, the less the state of the electricity storage device 20 changes. Therefore, the measurement device 24 can obtain more stable measurement results as the current flowing through the electricity storage device 20 is smaller.
　例えば、蓄電デバイス２０に流れる電流を５Ａ以上とすると、蓄電デバイス２０の状態を監視する車載の監視装置が異常を検出し得る。この場合、監視装置が有する機能によって、車両１２が起動不能になったり、走行不能になったりすることがある。 For example, if the current flowing through the electricity storage device 20 is 5 A or more, an in-vehicle monitoring device that monitors the state of the electricity storage device 20 may detect an abnormality. In this case, depending on the function of the monitoring device, the vehicle 12 may become unable to start or run.
　そこで、蓄電デバイス２０に流れる電流を５Ａ未満とすることで、監視装置における異常の検出を抑制することができる。 Therefore, by setting the current flowing through the power storage device 20 to less than 5 A, it is possible to suppress the detection of abnormality in the monitoring device.
　一方で、蓄電デバイス２０に流れる電流が小さすぎると、蓄電デバイス２０の内部抵抗による電圧変化が小さくなり、測定結果がノイズの影響を受けやすくなる。 On the other hand, if the current flowing through the electricity storage device 20 is too small, the voltage change due to the internal resistance of the electricity storage device 20 will be small, and the measurement results will be susceptible to noise.
　一例として、蓄電デバイス２０の出力電圧が４００Ｖで、蓄電デバイス２０の内部抵抗が、０．０３Ω以上０．１０Ω以下の場合、蓄電デバイス２０に流れる電流を１Ａ以上５Ａ未満の範囲で設定することが望ましい。 As an example, when the output voltage of the electricity storage device 20 is 400V and the internal resistance of the electricity storage device 20 is 0.03Ω or more and 0.10Ω or less, the current flowing through the electricity storage device 20 can be set in the range of 1A or more and less than 5A. desirable.
　なお、計測装置２４にノイズを除去する機能などがあれば、蓄電デバイス２０に流れる電流を１Ａ未満としても、計測可能である。 Note that if the measurement device 24 has a function of removing noise, it is possible to measure even if the current flowing through the electricity storage device 20 is less than 1A.
　測定信号は、正弦波又は矩形波を含む。 　The measurement signal includes a sine wave or a square wave.
　測定信号が正弦波の場合、測定信号の周波数を、蓄電デバイス２０である蓄電池の電解液及び配線の周波数応答が測定できる帯域とすることができる。また、測定信号が正弦波の場合、測定信号の周波数を、蓄電デバイス２０の電極反応過程の周波数応答が測定できる帯域とすることができる。さらに、測定信号が正弦波の場合、測定信号の周波数を、蓄電デバイス２０における拡散過程の周波数応答が測定できる帯域とすることができる。 When the measurement signal is a sine wave, the frequency of the measurement signal can be set to a band in which the frequency response of the electrolyte and wiring of the storage battery, which is the electricity storage device 20, can be measured. Moreover, when the measurement signal is a sine wave, the frequency of the measurement signal can be set to a band in which the frequency response of the electrode reaction process of the electricity storage device 20 can be measured. Furthermore, when the measurement signal is a sine wave, the frequency of the measurement signal can be set to a band in which the frequency response of the diffusion process in the electricity storage device 20 can be measured.
　前述した測定信号の周波数を数値で示すと、測定信号が正弦波の場合、測定信号の周波数を１０ｋＨｚ以上１００Ｈｚ以下とすることができる。また、測定信号が正弦波の場合、測定信号の周波数を５ｋＨｚ以上５００Ｈｚ以下とすることができる。さらに、測定信号が正弦波の場合、測定信号の周波数を１ｋＨｚとすることができる。 When the frequency of the measurement signal described above is shown numerically, when the measurement signal is a sine wave, the frequency of the measurement signal can be 10 kHz or more and 100 Hz or less. Moreover, when the measurement signal is a sine wave, the frequency of the measurement signal can be set to 5 kHz or more and 500 Hz or less. Furthermore, if the measurement signal is a sine wave, the frequency of the measurement signal can be 1 kHz.
　ここで、１ｋＨｚの測定信号は、蓄電デバイス２０の状態と相関性が高いことが知られている。このため、測定信号の周波数を１ｋＨｚとすることで、蓄電デバイス２０の状態をより高精度に測定することが可能となる。 Here, it is known that the 1 kHz measurement signal has a high correlation with the state of the electricity storage device 20 . Therefore, by setting the frequency of the measurement signal to 1 kHz, the state of the power storage device 20 can be measured with higher accuracy.
　また、測定信号の周波数を１ｋＨｚに固定することで、単一の周波数による短時間での測定が容易に可能となる。 In addition, by fixing the frequency of the measurement signal to 1 kHz, it is possible to easily perform short-time measurement using a single frequency.
　そして、測定信号をＭ系列信号とすることができる。Ｍ系列信号は、疑似白色二値信号であり、人為的に生成した不規則信号である。 Then, the measurement signal can be an M-sequence signal. The M-sequence signal is a pseudo-white binary signal, which is an artificially generated random signal.
　測定信号が矩形波の場合、矩形波には複数の周波数成分が含まれる。このため、測定信号を矩形波にすることによって、単一の周波数の信号を複数入力するよりも測定の簡素化を図ることが可能となる。 When the measurement signal is a square wave, the square wave contains multiple frequency components. Therefore, by using a rectangular wave as the measurement signal, it is possible to simplify the measurement rather than inputting a plurality of signals of a single frequency.
　そして、測定部９０は、電圧測定部１００で測定した電圧の変化及び電流測定部１０２で測定した電流の変化に基づいて、蓄電デバイス２０の周波数応答を測定して交流抵抗を取得する。また、測定部９０は、予め取得した蓄電デバイス２０の交流抵抗と蓄電デバイス２０の劣化度合いとの関係に基づいて、取得した交流抵抗から測定した蓄電デバイス２０の劣化度合いを推定する。 Then, the measurement unit 90 measures the frequency response of the electricity storage device 20 and obtains the AC resistance based on the voltage change measured by the voltage measurement unit 100 and the current change measured by the current measurement unit 102 . Further, the measurement unit 90 estimates the degree of deterioration of the electricity storage device 20 measured from the obtained AC resistance, based on the previously obtained relationship between the AC resistance of the electricity storage device 20 and the degree of deterioration of the electricity storage device 20 .

　また、第一実施形態の第二変形例における計測システム１１００においては、計測装置１０１４が電力の供給を受ける為のサブ接続部８４－１が接続部８４から独立して設けられている。このため、計測システム１１００は、サブ接続部８４－１の接続先と接続部８４の接続先とが離れている場合であっても、計測装置１０１４の電力の供給が可能となる。 Also, in the measurement system 1100 according to the second modification of the first embodiment, a sub-connection section 84-1 for receiving power supply to the measurement device 1014 is provided independently of the connection section 84.

Further, the power storage side communication unit 70 of the first embodiment is abolished, and the transmission receiving unit 60 of the power storage device 22 is configured only with the power receiving unit 62 .
　計測装置２４の接続部８４が蓄電装置２２に接続されると、供給部９４から出力された電圧信号が蓄電装置２２の受給部６２へ供給される。すると、受給部６２は、計測装置２４から供給された電圧信号を断続部４８に供給して断続部４８のスイッチ回路５０をオンにする。これにより、負極被接続部４４と蓄電デバイス２０の負極とが通電状態となる。 When the connecting portion 84 of the measuring device 24 is connected to the power storage device 22 , the voltage signal output from the supply portion 94 is supplied to the power receiving portion 62 of the power storage device 22 . Then, the receiving section 62 supplies the voltage signal supplied from the measuring device 24 to the intermittent section 48 to turn on the switch circuit 50 of the intermittent section 48 . As a result, the negative electrode connected portion 44 and the negative electrode of the electricity storage device 20 are brought into an energized state.
　一方、計測装置２４の接続部８４を蓄電装置２２から離脱すると、蓄電装置２２の受給部６２に供給された電圧信号が遮断される。すると、断続部４８に供給された電圧信号も遮断され、スイッチ回路５０がオフとなる。これにより、負極被接続部４４と蓄電デバイス２０の正極とが非通電状態となる。 On the other hand, when the connecting portion 84 of the measuring device 24 is disconnected from the power storage device 22, the voltage signal supplied to the power receiving portion 62 of the power storage device 22 is cut off. Then, the voltage signal supplied to the intermittent section 48 is also interrupted, and the switch circuit 50 is turned off. As a result, the negative electrode connected portion 44 and the positive electrode of the electricity storage device 20 are in a non-energized state.
