Each of the secondary batteries 71 to 7n is connected in common to the connector terminals 6a and 6b and the negative electrode to the connector terminals 6c and 6d, respectively, by internal wiring.

充放電試験装置1は、コンピュータ8により充放電試験を行う。充放電試験装置1のコントローラ3は、コンピュータ8から充放電試験指令が与えられると、各チャネルの充放電電源41〜4nを制御して、電池トレイ2上の各二次電池71〜7nを充放電する。二次電池71〜7nからの充放電性能に対応した電圧/電流は、各チャネルの充放電電源41〜4nの端子S+、S−を経て、各チャネルの充放電電源41〜4nにフィードバックされ、コントローラ3に伝達され、二次電池71〜7nの充放電性能等の試験が行われる。   The charge / discharge test apparatus 1 performs a charge / discharge test using the computer 8.

このような充放電試験装置1では、充放電試験の品質の向上や精度向上のため、以下の要領で、各チャネルの充放電電源を各校正ポイントで校正することが行われる。   In such a charge / discharge test apparatus 1, in order to improve the quality and accuracy of the charge / discharge test, the charge / discharge power source of each channel is calibrated at each calibration point in the following manner.

図7を参照して各チャネルの充放電電源41〜4nに対する校正を説明する。A,Bはそれぞれ充放電電源41〜4nを校正するに際して、これら充放電電源41〜4nに抵抗負荷,直流電源を接続するための装置であり、基本構成として、充放電電源のコネクタ端子5a〜5dに接続可能な4つのコネクタ端子9a〜9dからなるコネクタ9と、コネクタ端子9aの配線に接続されたシャント抵抗10と、シャント抵抗10を流れる電流を測定する電流メータ11と、コネクタ端子9a,9d間の電圧を測定する電圧メータ12とを具備する。   Calibration for the charge / discharge power supplies 41 to 4n of each channel will be described with reference to FIG. A and B are devices for connecting a resistance load and a DC power source to the charge / discharge power sources 41 to 4n when calibrating the charge / discharge power sources 41 to 4n, respectively. A connector 9 comprising four connector terminals 9a to 9d connectable to 5d, a shunt resistor 10 connected to the wiring of the connector terminal 9a, a current meter 11 for measuring a current flowing through the shunt resistor 10, and connector terminals 9a, And a voltage meter 12 for measuring a voltage between 9d.

一方の装置Aは、抵抗負荷Rを備え、他方の装置Bは、直流電源Pを備える。   One device A includes a resistance load R, and the other device B includes a DC power source P.

充電時には装置Aのコネクタ9の各コネクタ端子9a〜9dを充放電試験装置1の第1チャネル(ch1)の充放電電源41のコネクタ端子5a〜5dに接続する。そして、コンピュータ8からの校正指令に応答して、充放電試験装置1のコントローラ3は、第1チャネル(ch1)の充放電電源41を校正ポイントの電圧、電流で充電モード運転する。このときの各メータ11,12のメータ指示値と第1チャネル(ch1)の充放電電源41の内部モニタ値とを読み取って校正し、この校正の値を記録する。   At the time of charging, the connector terminals 9a to 9d of the connector 9 of the apparatus A are connected to the connector terminals 5a to 5d of the charge / discharge power supply 41 of the first channel (ch1) of the charge / discharge test apparatus 1. In response to the calibration command from the computer 8, the controller 3 of the charge / discharge test apparatus 1 operates the charge / discharge power supply 41 of the first channel (ch1) in the charge mode with the voltage and current at the calibration point. At this time, the meter indication values of the meters 11 and 12 and the internal monitor value of the charge / discharge power supply 41 of the first channel (ch1) are read and calibrated, and the value of this calibration is recorded.

次いで、装置Bのコネクタ9の各コネクタ端子9a〜9dを充放電試験装置1の第1チャネル(ch1)の充放電電源41のコネクタ端子5a〜5dに接続する。そして、コンピュータ8からの校正指令に応答して、充放電試験装置1のコントローラ3は、第1チャネル(ch1)の充放電電源41を校正ポイントの電圧、電流で放電モード運転する。このときの各メータ11,12のメータ指示値と第1チャネル(ch1)の充放電電源41の内部モニタ値を読み取り、メータ指示値と内部モニタ値とから校正し、この校正の値を記録する。そして、別の校正ポイントで前記のことを繰り返す。こうして第1充放電電源41の校正が終了すると、次チャネル(ch2,ch3,…,chn)以降の充放電電源42〜4nについても同様の校正を行う。   Next, the connector terminals 9 a to 9 d of the connector 9 of the apparatus B are connected to the connector terminals 5 a to 5 d of the charge / discharge power supply 41 of the first channel (ch1) of the charge / discharge test apparatus 1. In response to the calibration command from the computer 8, the controller 3 of the charge / discharge test apparatus 1 operates the charge / discharge power source 41 of the first channel (ch1) in the discharge mode with the voltage and current at the calibration point. At this time, the meter indication values of the meters 11 and 12 and the internal monitor value of the charge / discharge power supply 41 of the first channel (ch1) are read, calibrated from the meter indication value and the internal monitor value, and the value of this calibration is recorded. . The above is repeated at another calibration point. When the calibration of the first charging / discharging power supply 41 is thus completed, the same calibration is performed for the charging / discharging power supplies 42 to 4n after the next channel (ch2, ch3,..., Chn).

しかしながら、このような校正では、1チャネル当たりの充放電電源の校正に、通常20〜25分程度の時間が必要であるので、全チャネルの充放電電源全てに対して校正が終了するまでには多大な時間と労力とが要求される。さらに、そのうえその校正に基づいて調整するのに多大な時間がかかる。また、前記校正では、メータ指示値を読み取る必要があるので、読み取りミスや記録ミス、さらに、メータ指示値のばらつきが正常範囲内であれば、それ以上にメータ指示値の妥当性を判断できる効果的な手段が無く、多少のミスをしても検査員が気付かない可能性があるなど、人為的ミスが起こり得る。   However, such calibration usually requires about 20 to 25 minutes to calibrate the charge / discharge power source per channel, so that the calibration for all the charge / discharge power sources of all channels is completed. A great deal of time and effort is required. Furthermore, it takes a lot of time to adjust based on the calibration. In addition, the calibration requires the reading of the meter indication value, so that the validity of the meter indication value can be judged further if reading errors, recording errors, and variations in the meter indication value are within the normal range. Human error can occur, for example, there is a possibility that the inspector may not notice even if there are no mistakes.

結局、従来の校正では、充放電試験装置の試験品質の低下ないしは精度低下となり、充放電電源の出力上限付近で校正するため、容量が大きい直流電源と負荷抵抗等が必要となるから、装置価格が高くそのメンテナンスも手間を必要とする大掛かりなものとなる。   After all, in the conventional calibration, the test quality of the charge / discharge test equipment is lowered or the accuracy is lowered, and since the calibration is performed near the output upper limit of the charge / discharge power supply, a large-capacity DC power supply and load resistance are required. It is expensive and requires a lot of maintenance.

本発明は、上記に鑑みて為されたものであり、校正を自動化することにより、前記校正/調整時間の大幅短縮ならびに、前記人為的ミスの解消と作業の簡易化、校正のために要する装置の簡易化を図り、もって、充放電試験の品質向上と共に、装置価格と装置メンテナンスの費用低減化を可能とすることを解決すべき課題としている。   The present invention has been made in view of the above, and by automating calibration, the calibration / adjustment time is greatly shortened, the human error is eliminated, the work is simplified, and the apparatus is required for calibration. Therefore, it is a problem to be solved to improve the quality of the charge / discharge test and to reduce the cost of the device and the cost of the device maintenance.

各充放電電源41〜4nは、それぞれ、正負一対の電源端子P,N、および正負一対の検知端子S+,S−を有する。電源端子P,Nは、試験対象である二次電池を充電したり、二次電池を放電させたりするための電圧、電流を入出力する端子であり、検知端子S+,S−は、試験対象である二次電池に対する充放電電圧や充放電電流を検知するための端子である。   Each of the charging / discharging power supplies 41 to 4n has a pair of positive and negative power supply terminals P and N and a pair of positive and negative detection terminals S + and S−. The power terminals P and N are terminals for inputting and outputting voltage and current for charging a secondary battery as a test target and discharging the secondary battery, and detection terminals S + and S- are test targets. It is a terminal for detecting the charging / discharging voltage and charging / discharging current with respect to the secondary battery which is.

充放電試験装置1Aは、図1上、右側端部にコネクタ5を備える。このコネクタ5は、各チャネルの充放電電源41〜4nごとに4つ1組のコネクタ端子5a〜5dを、一定間隔でn組備える。コネクタ5内で各コネクタ端子5aは充放電電源41〜4nの各正電源端子Pに、各コネクタ端子5bは充放電電源41〜4nの各検知端子S+に、各コネクタ端子5cは充放電電源41〜4nの各検知端子S−に、各コネクタ端子5dは充放電電源41〜4nの各負電源端子Nに各々配線接続されている。   The charge / discharge test apparatus 1A includes a connector 5 at the right end in FIG. The connector 5 includes n sets of four connector terminals 5a to 5d at regular intervals for each of the charge / discharge power sources 41 to 4n of each channel. In the connector 5, each connector terminal 5 a is connected to each positive power supply terminal P of the charge / discharge power supplies 41 to 4 n, each connector terminal 5 b is connected to each detection terminal S + of the charge / discharge power supplies 41 to 4n, and each connector terminal 5 c is connected to the charge / discharge power supply 41. The connector terminals 5d are connected to the negative power supply terminals N of the charge / discharge power supplies 41 to 4n by wiring connection to the detection terminals S- of -4n, respectively.

校正装置20は、単一の校正ボード構成であり、図上、左側端部に、コネクタ21を備える。このコネクタ21は、4つ1組のコネクタ端子21a〜21dを充放電試験装置1Aの各組のコネクタ5のコネクタ端子5a〜5dと同間隔でn組有する。これにより校正装置20は、充放電試験装置1Aに対して、互いのコネクタ5,21で装脱することができる。   The calibration device 20 has a single calibration board configuration, and includes a connector 21 at the left end in the figure. This connector 21 has n sets of four connector terminals 21a to 21d at the same interval as the connector terminals 5a to 5d of each set of connectors 5 of the charge / discharge test apparatus 1A. Thereby, the calibration apparatus 20 can be attached / detached to / from the charge / discharge test apparatus 1 </ b> A with the mutual connectors 5, 21.

校正装置20において、コネクタ21の各組におけるコネクタ端子21a同士、21b同士、21c同士、21d同士は、内部配線L1〜L4で共通接続されている。また、内部配線L3とL4は内部配線L5で接続され、内部配線L1とL2は内部配線L6で接続されている。   In the calibration device 20, the connector terminals 21a, 21b, 21c, and 21d in each set of connectors 21 are commonly connected by internal wirings L1 to L4.

Since the internal wiring L1 is connected to each pair of connector terminals 21a of the connector 21, when the charge / discharge test apparatus 1A and the calibration apparatus 20 are connected to each other by the connectors 5 and 21, the connectors of each pair of the connectors 21 are connected. The terminal 21a is connected to the terminal P of each of the charge / discharge power supplies 41 to 4n of the charge / discharge test apparatus 1A, whereby the current from the terminal P flows from the connectors 5 and 21 to the current measuring element 23 provided in the internal wiring L1. This current can be measured by the current measuring unit 24. Both the measurement units 22 and 24 are connected to the control unit 25.

制御部25は、マイクロコンピュータからなり、CPU、内部メモリおよび通信インターフェース等を含み、各電圧、電流両測定部22、24それぞれの測定出力を内部メモリに記憶制御することができる。制御部25と充放電試験装置1Aのコントローラ3においては、充放電試験装置1Aと校正装置20とが互いのコネクタ5,21で接続されると、互いの通信線CL1,CL2が接続される。制御部25は、この通信線CL1,CL2の接続により通信インタ−フェースから通信線CL1,CL2を介してコントローラ3と通信し、内部メモリに記憶していた測定データをコントローラ3に送信することができるようになっている。   The control unit 25 includes a microcomputer and includes a CPU, an internal memory, a communication interface, and the like, and can store and control the measurement outputs of the voltage and current measurement units 22 and 24 in the internal memory. In the controller 3 of the controller 25 and the charge / discharge test apparatus 1A, when the charge / discharge test apparatus 1A and the calibration apparatus 20 are connected by the connectors 5 and 21, the communication lines CL1 and CL2 are connected. The control unit 25 communicates with the controller 3 from the communication interface via the communication lines CL1 and CL2 through the connection of the communication lines CL1 and CL2, and transmits the measurement data stored in the internal memory to the controller 3. It can be done.

そして、校正装置20は、コネクタ21の各組におけるコネクタ端子21a〜21dが、図2で説明する電池トレイ2のコネクタ6の各組におけるコネクタ端子6a〜6dと共通した同じコネクタ配置であるので、校正装置20により、充放電試験装置1Aの各充放電電源41〜4nの校正後は、充放電試験装置1Aに対して、校正装置20を図1から図2に示すように電池トレイ2に差し替えることができる。   In the calibration device 20, the connector terminals 21a to 21d in each set of connectors 21 have the same connector arrangement common to the connector terminals 6a to 6d in each set of connectors 6 of the battery tray 2 described in FIG. After the calibration of the charge / discharge power supplies 41 to 4n of the charge / discharge test apparatus 1A by the calibration apparatus 20, the calibration apparatus 20 is replaced with the battery tray 2 as shown in FIGS. be able to.

充放電試験装置1Aは、コンピュータ8に通信線で接続され、充放電試験装置1Aのコントローラ3は、コンピュータ8から充放電試験指令や校正指令が与えられるようになっている。なお、コンピュータ8を設けず、充放電試験装置1Aそれ自体に校正指令を開始するための操作部を設けるなどし、この操作部の操作によりコントローラ3が校正を自動開始できるようにしてもよい。   The charge / discharge test apparatus 1 </ b> A is connected to the computer 8 via a communication line, and the controller 3 of the charge / discharge test apparatus 1 </ b> A is supplied with a charge / discharge test instruction and a calibration instruction from the computer 8. In addition, without providing the computer 8, an operation unit for starting a calibration command may be provided in the charge / discharge test apparatus 1 </ b> A itself, and the controller 3 may automatically start calibration by operating this operation unit.

以下に、実施形態の校正を説明する。   Hereinafter, the calibration of the embodiment will be described.

まず、充放電試験装置1Aと校正装置20とを互いのコネクタ5,21により接続する。この接続により、校正装置20の制御部25と充放電試験装置1Aのコントローラ3とが互いの通信線CL1,CL2により接続されることになる。そして、コンピュータ8から充放電試験装置1Aのコントローラ3に校正指令が与えられると、充放電試験装置1Aのコントローラ3は、以下の校正を行う。ただし、以下の校正および充放電電源41〜4nに対する校正の順序は説明の理解のための一例である。   First, the charge / discharge test apparatus 1 </ b> A and the calibration apparatus 20 are connected by the connectors 5 and 21. With this connection, the control unit 25 of the calibration apparatus 20 and the controller 3 of the charge / discharge test apparatus 1A are connected by the communication lines CL1 and CL2. When a calibration command is given from the computer 8 to the controller 3 of the charge / discharge test apparatus 1A, the controller 3 of the charge / discharge test apparatus 1A performs the following calibration. However, the following calibration and calibration sequences for the charge / discharge power supplies 41 to 4n are examples for understanding the description.

すなわち、各充放電電源41〜4nのうち、充放電電源41をチャネルAとして、直流電源および抵抗負荷として動作させる充放電電源に選定し、他の充放電電源42〜4nをチャネルB1,B2…B(n−1)とし、それらチャネルB1,B2…B(n−1)の充放電電源のうち、任意チャネルBxの充放電電源を校正対象の充放電電源とする。この校正時では、校正対象であるチャネルBxの充放電電源以外の他のチャネルの充放電電源の動作を全て停止させる。そして、校正対象の充放電電源を他のチャネルB1,B2,…,B(n−1)に変更していき、順次、チャネルB1,B2…B(n−1)の充放電電源42〜4n全ての校正を行う。そして、チャネルB1〜B(n−1)チャネルの充放電電源42〜4nの校正が終了すると、チャネルAの充放電電源41を校正対象の充放電電源とし、チャネルB1〜B(n−1)の充放電電源42〜4nのいずれか任意チャネルの充放電電源を、チャネルAの充放電電源41の校正のための抵抗負荷、直流電源として制御する。   That is, among the charging / discharging power supplies 41 to 4n, the charging / discharging power supply 41 is selected as the channel A, and the charging / discharging power supply operating as the DC power supply and the resistance load is selected. B (n-1), and among the charge / discharge power sources of the channels B1, B2,... B (n-1), the charge / discharge power source of the arbitrary channel Bx is the charge / discharge power source to be calibrated. At the time of this calibration, all the operations of the charge / discharge power sources of the channels other than the charge / discharge power source of the channel Bx to be calibrated are stopped. Then, the charge / discharge power source to be calibrated is changed to the other channels B1, B2,..., B (n-1), and the charge / discharge power sources 42 to 4n of the channels B1, B2,. Perform all calibrations. When the calibration of the charge / discharge power sources 42 to 4n of the channels B1 to B (n-1) is completed, the charge / discharge power source 41 of the channel A is set as the charge / discharge power source to be calibrated, and the channels B1 to B (n-1). The charging / discharging power source of any channel of the charging / discharging power sources 42 to 4n is controlled as a resistance load and a DC power source for calibration of the charging / discharging power source 41 of the channel A.

まず、例えばBx=B1とし、チャネルB1の充放電電源42が二次電池を充電させて試験を行う充電モードの校正時は、前記校正のための抵抗負荷としてチャネルAの充放電電源41を放電モードで動作させる。チャネルB1の充放電電源42が二次電池を放電させて試験を行う放電モードの校正時は、前記校正のための直流電源としてチャネルAの充放電電源41を充電モードで動作させる。
(1) Calibration of charge / discharge power source for channel Bx:

Operate in mode. At the time of calibration of the discharge mode in which the charge / discharge power source 42 of the channel B1 discharges the secondary battery and performs the test, the charge / discharge power source 41 of the channel A is operated in the charge mode as a DC power source for the calibration.

次に、チャネルB2の充放電電源43が二次電池を充電させて試験を行う充電モードの校正時は、抵抗負荷回路としてチャネルAの充放電電源41を放電モードで動作させる。チャネルB2の充放電電源43が二次電池を放電させて試験を行う放電モードの校正時は、直流電源回路としてチャネルAの充放電電源41を充電モードで動作させる。   Next, at the time of calibration of the charging mode in which the charging / discharging power source 43 of the channel B2 charges the secondary battery to perform the test, the charging / discharging power source 41 of the channel A is operated in the discharging mode as a resistance load circuit. At the time of calibration of the discharge mode in which the charge / discharge power supply 43 of the channel B2 discharges the secondary battery and performs the test, the charge / discharge power supply 41 of the channel A is operated in the charge mode as a DC power supply circuit.

こうして順次にそれ以降の充放電電源に対して校正を繰り返し、最後のチャネルB(n−1)の充放電電源4nが二次電池を充電させて試験を行う充電モードの校正時は、抵抗負荷回路としてチャネルAの充放電電源41を放電モードで動作させ、チャネルB(n−1)の充放電電源4nが二次電池を放電させて試験を行う放電モードの校正時は、直流電源回路としてチャネルAの充放電電源41を充電モードで動作させる。こうしてチャネルB1〜B(n−1)の充放電電源42〜4nのすべての校正が終了する。   In this way, the calibration is sequentially repeated for the subsequent charge / discharge power supplies, and the charge / discharge power supply 4n of the last channel B (n-1) charges the secondary battery to perform the test. As a circuit, the channel A charge / discharge power supply 41 is operated in the discharge mode, and the charge / discharge power supply 4n of the channel B (n-1) discharges the secondary battery to perform the test. The charge / discharge power source 41 of the channel A is operated in the charge mode. Thus, all the calibrations of the charge / discharge power sources 42 to 4n of the channels B1 to B (n-1) are completed.

(2)、チャネルAの充放電電源の校正:
チャネルAの充放電電源41が二次電池を充電させて試験を行う充電モードの校正時は、抵抗負荷としてチャネルB1〜B(n−1)の充放電電源42〜4nのいずれか1チャネルの充放電電源を放電モードで動作させる。
(2) Calibration of channel A charge / discharge power supply:
When calibrating the charging mode in which the charging / discharging power source 41 of the channel A charges the secondary battery to perform the test, any one of the charging / discharging power sources 42 to 4n of the channels B1 to B (n-1) is used as a resistive load. The charge / discharge power supply is operated in the discharge mode.

チャネルAの充放電電源41が二次電池を放電させて試験を行う放電モードの校正時は、直流電源としてチャネルB1〜B(n−1)の充放電電源42〜4nのいずれか1チャネルの充放電電源を充電モードで動作させる。   When calibrating the discharge mode in which the charge / discharge power source 41 of the channel A discharges the secondary battery to perform the test, any one of the charge / discharge power sources 42 to 4n of the channels B1 to B (n-1) is used as the DC power source. The charge / discharge power supply is operated in the charge mode.

(3)、前記(1)(2)で、それぞれの校正ポイントでの検知電圧を電圧測定部22で測定し、チャネル間電流を電流測定部24で測定し、この実電圧/電流測定値を制御部25に記憶し、制御部25は前記記憶した測定値を、通信線CL1,CL2を介して、充放電試験装置1Aのコントローラ3に送信する。   (3) In (1) and (2), the voltage measurement unit 22 measures the detection voltage at each calibration point, the channel-to-channel current is measured by the current measurement unit 24, and the actual voltage / current measurement value is calculated. It memorize | stores in the control part 25, and the control part 25 transmits the said memorize | stored measured value to the controller 3 of 1 A of charge / discharge test apparatuses via communication line CL1, CL2.

充放電試験装置1Aのコントローラ3は、校正対象の充放電電源ごとに前記送信されてきた実電圧/電流測定値を、当該校正対象の充放電電源の内部電圧/電流モニタ値と比較する。内部電圧/電流モニタ値とは、抵抗負荷または直流電源に利用された充放電電源から校正対象の充放電電源に直接取り込まれ内部で演算された値である。この内部電圧/電流モニタ値は、当該校正対象の充放電電源から前記コントローラ3に入力される。   The controller 3 of the charge / discharge test apparatus 1A compares the transmitted actual voltage / current measured value for each calibration target charge / discharge power supply with the internal voltage / current monitor value of the calibration target charge / discharge power supply. The internal voltage / current monitor value is a value that is directly taken into a charge / discharge power source to be calibrated from a charge / discharge power source used for a resistive load or a DC power source and calculated internally. The internal voltage / current monitor value is input to the controller 3 from the charge / discharge power source to be calibrated.

充放電試験装置1Aのコントローラ3は、その校正ポイントで、実電圧/電流測定値と内部電圧/電流モニタ値との差分を校正値として演算し、その校正値から逆算で校正対象の充放電電源の調整を行い、また、校正値の範囲やばらつきなどからの良否判断の検査を行う。   The controller 3 of the charge / discharge test apparatus 1A calculates the difference between the actual voltage / current measurement value and the internal voltage / current monitor value as a calibration value at the calibration point, and performs a reverse calculation from the calibration value to charge / discharge power supply to be calibrated. In addition, the quality is judged from the range and variation of the calibration value.

こうしたコントローラ3の処理結果は、コンピュータ8に送信されて記録される。調整値に関しては、校正対象の充放電電源の内部制御回路に送出され、それ以降は校正対象とされた充放電電源は、この調整値により電圧/電流を補正する。   The processing result of the controller 3 is transmitted to the computer 8 and recorded. The adjustment value is sent to the internal control circuit of the charge / discharge power supply to be calibrated, and thereafter, the charge / discharge power supply to be calibrated corrects the voltage / current with this adjustment value.

そして、充放電試験装置1Aの各チャネルの充放電電源41〜4nの全ての校正が終了すると、校正装置20のコネクタ21を充放電試験装置1Aのコネクタ5から外し、次いで、充放電試験装置1Aのコネクタ5に電池トレイ2のコネクタ6を接続することで、充放電試験装置1Aに対して、校正装置20を電池トレイ2と入れ替え、充放電電源41〜4nが校正済みの充放電試験装置1Aにより、電池トレイ2に搭載した二次電池71〜7nの充放電試験を行うとよい。   When all the calibrations of the charge / discharge power sources 41 to 4n of the respective channels of the charge / discharge test apparatus 1A are completed, the connector 21 of the calibration apparatus 20 is disconnected from the connector 5 of the charge / discharge test apparatus 1A, and then the charge / discharge test apparatus 1A. By connecting the connector 6 of the battery tray 2 to the connector 5, the calibration device 20 is replaced with the battery tray 2 for the charge / discharge test device 1A, and the charge / discharge test device 1A in which the charge / discharge power sources 41 to 4n have been calibrated. Thus, the charge / discharge test of the secondary batteries 71 to 7n mounted on the battery tray 2 may be performed.

以上説明したように実施の形態の校正装置20では、充放電電源41〜4nのすべてに対してその校正が自動的に行われるため、校正時間の大幅短縮ならびに、人為的ミスの解消、校正作業の簡易化等が可能となるなど、従来の課題を解消することができる。   As described above, in the calibration apparatus 20 according to the embodiment, the calibration is automatically performed for all of the charge / discharge power supplies 41 to 4n, so that the calibration time is greatly shortened, the human error is eliminated, and the calibration work is performed.
