Description

本発明は複数電池の評価装置に関する。   The present invention relates to a multiple battery evaluation apparatus.

特許文献１には、恒温槽内の電池の特性を試験評価する複数電池の自動試験装置が開示されている。当該自動試験装置では、単一の充放電装置が、複数の恒温槽を制御する。また、単一の電池が過剰な電圧値、又は温度で動作する等、異常な動作をしたとき、この充放電装置が、複数の電池の動作を停止して、試験全体を停止する。   Patent Document 1 discloses an automatic test apparatus for a plurality of batteries that tests and evaluates the characteristics of the batteries in the thermostat.

In addition, when a single battery operates abnormally, such as operating at an excessive voltage value or temperature, the charging / discharging device stops the operation of the plurality of batteries and stops the entire test.

特開平１１−２７３７５１号公報Japanese Patent Laid-Open No. 11-273751

このような装置では、単一の充放電装置が、複数の電池の充放電動作を一括して制御しており、単一の電池が異常な動作をしたとき、複数の電池の動作を一括して停止する。   In such a device, a single charging / discharging device collectively controls charging / discharging operations of a plurality of batteries, and when a single battery performs an abnormal operation, the operations of the plurality of batteries are collectively controlled. And stop.

電池は恒温槽内に位置するため、一旦高い温度に達した後、降温しにくい。そのため、電池の動作が異常と判断されると、正常と判断されるまで、長い時間かかる。他の電池で試験を再始動できないため、複数電池の評価試験の稼働率が低下するおそれがあった。   Since the battery is located in the thermostat, it is difficult to lower the temperature once it reaches a high temperature. Therefore, if it is determined that the battery operation is abnormal, it takes a long time until it is determined to be normal. Since the test could not be restarted with another battery, there was a risk that the operating rate of the evaluation test for multiple batteries would be reduced.

本発明は、複数電池の評価試験の稼働率の低下するおそれを抑制するものとする。   This invention shall suppress a possibility that the operation rate of the evaluation test of multiple batteries may fall.

前記温度監視ユニットは、温度が正常温度の範囲外にある電池を検出した場合、又は、前記電圧監視ユニットは、電圧が正常電圧の範囲外にある電池を検出した場合において、

A plurality of thermostats each having a battery;
A charging / discharging device for charging / discharging the battery;
A temperature monitoring unit for monitoring the temperature of the battery;
A voltage monitoring unit for monitoring the voltage of the battery, and a multiple battery evaluation device comprising:
When the temperature monitoring unit detects a battery whose temperature is outside the normal temperature range, or when the voltage monitoring unit detects a battery whose voltage is outside the normal voltage range,
The charging / discharging device stops charging / discharging only the detected battery.

このような構成によれば、異常が発生したと判断されても、異常発生した電池のみ充放電が停止される。そのため、その他の電池の試験を続行することが可能となり、稼働率が向上する。   According to such a configuration, even if it is determined that an abnormality has occurred, charging / discharging of only the battery in which the abnormality has occurred is stopped. Therefore, it becomes possible to continue the test of other batteries, and the operating rate is improved.

本発明は、複数電池の評価試験の稼働率の低下するおそれを抑制することができる。   The present invention can suppress the possibility that the operating rate of the evaluation test of a plurality of batteries will decrease.

（複数電池の評価装置の動作例１）
次に、図２及び図３を参照して、特定の電池２０＋Ｘが異常な動作をしている場合の、複数電池の評価装置の一動作例について説明する。図２は、上限異常発生時における複数電池の評価装置の一動作例のフローチャートである。図３は、上限異常解除時における複数電池の評価装置の一動作例のフローチャートである。電池２０＋Ｘは、電池２１、電池２２、電池２３、…、及び電池２０＋Ｎの少なくとも１つである。 (Operation example 1 of multiple battery evaluation device)
Next, with reference to FIG.2 and FIG.3, the operation example of the evaluation apparatus of multiple batteries when the specific battery 20 + X is operating abnormally will be described. FIG. 2 is a flowchart of an operation example of the evaluation apparatus for a plurality of batteries when an upper limit abnormality occurs. FIG. 3 is a flowchart of an operation example of the evaluation apparatus for a plurality of batteries when canceling the upper limit abnormality. Battery 20 + X is at least one of battery 21, battery 22, battery 23,..., And battery 20 + N.

図２に示すように、温度監視ユニット１３が、チャンネルＣＨ Ｘについて恒温槽Ｘの電池２０＋Ｘの電圧値又は温度の異常を検出し、安全制御機構１１が、チャンネルＣＨ Ｘによる恒温槽Ｘに含まれる全チャンネルＣＨについてインターロック信号を送る（ステップＳＴ１１）。ここで、Ｘは、１以上の任意の自然数である。具体的には、温度監視ユニット１３が、チャンネルＣＨ Ｘについて恒温槽Ｘの電池２０＋Ｘの温度が上限Ｕｔ１を超えたこと、又は、電池２０＋Ｘの電圧値が上限Ｕｅ１を超えたことを検出して、電池２０＋Ｘの異常を判定する。温度監視ユニット１３は、電池２０＋Ｘに異常が発生したと判定すると、安全制御機構１１へ異常信号を送る。安全制御機構１１が異常信号に基づいて、チャンネルＣＨ Ｘによる温度センサが含まれる恒温槽Ｘに含まれる全チャンネルについてインターロック信号を送る。   As shown in FIG. 2, the temperature monitoring unit 13 detects an abnormality in the voltage value or temperature of the battery 20 + X in the thermostatic chamber X for the channel CH X, and the safety control mechanism 11 is included in the thermostatic chamber X by the channel CH X. An interlock signal is sent for all channels CH (step ST11). Here, X is an arbitrary natural number of 1 or more. Specifically, the temperature monitoring unit 13 detects that the temperature of the battery 20 + X in the thermostatic chamber X for the channel CH X exceeds the upper limit Ut1, or the voltage value of the battery 20 + X exceeds the upper limit Ue1, The abnormality of the battery 20 + X is determined. When the temperature monitoring unit 13 determines that an abnormality has occurred in the battery 20 + X, it sends an abnormality signal to the safety control mechanism 11. Based on the abnormal signal, the safety control mechanism 11 sends an interlock signal for all the channels included in the thermostatic chamber X including the temperature sensor by the channel CHX.

続いて、充放電装置１２が、恒温槽Ｘへ一部停止信号を出力する（ステップＳＴ１２）。   Subsequently, the charging / discharging device 12 outputs a partial stop signal to the thermostatic chamber X (step ST12).

続いて、恒温槽Ｘは、充放電装置１２から一部停止信号を受け取り、電池２０＋Ｘの充放電についての動作を保護停止する（ステップＳＴ１３）。電池２０＋Ｘ以外の電池２１、電池２２、電池２３、…、電池２０＋Ｎは、停止することなく、充放電などの動作を継続する。   Subsequently, the thermostatic chamber X receives a partial stop signal from the charging / discharging device 12, and protects and stops the operation for charging / discharging the battery 20 + X (step ST13). The battery 21, battery 22, battery 23,..., Battery 20 + N other than the battery 20 + X continue to operate such as charging / discharging without stopping.

その後、ユーザ等が安全や動作の正常性を確認する。この確認後、上限異常を解除するステップについて説明する。図３に示すように、リセット釦（ボタン）を押し下げる（ステップＳＴ２１）。すると、電池２０＋Ｘの温度が上限Ｕｔ１を下回り、又は、電池２０＋Ｘの電圧値が上限Ｕｅ１を下回る等して、電池２０＋Ｘの異常が解消されていれば（ステップＳＴ２２：ＹＥＳ）、異常がリセットされ、電池２０＋Ｘは、再び充放電を開始する（ステップＳＴ２３）。   Thereafter, the user or the like confirms safety and normality of operation. After this confirmation, the step of canceling the upper limit abnormality will be described. As shown in FIG. 3, the reset button (button) is pressed down (step ST21). Then, if the abnormality of the battery 20 + X has been resolved by the temperature of the battery 20 + X being lower than the upper limit Ut1 or the voltage value of the battery 20 + X being lower than the upper limit Ue1 (step ST22: YES), the abnormality is reset, Battery 20 + X starts charging / discharging again (step ST23).

（複数電池の評価装置の動作例２）
次に、図４及び図５を参照して、特定の電池２０＋Ｘが異常な動作をしている場合の、複数電池の評価装置の一動作例について説明する。図４は、上上限異常発生時における複数電池の評価装置の一動作例のフローチャートである。図５は、上上限異常解除時における複数電池の評価装置の一動作例のフローチャートである。 (Operation example 2 of multiple battery evaluation device)
Next, with reference to FIG. 4 and FIG. 5, an operation example of the evaluation apparatus for a plurality of batteries when a specific battery 20 + X is operating abnormally will be described. FIG. 4 is a flowchart of an operation example of the evaluation apparatus for a plurality of batteries when the upper / upper limit abnormality occurs. FIG. 5 is a flowchart of an operation example of the evaluation apparatus for a plurality of batteries when the upper upper limit abnormality is canceled.

図４に示すように、温度監視ユニット１３が、チャンネルＣＨ Ｘについて恒温槽Ｘの電池２０＋Ｘの温度の異常を検出し、安全制御機構１１が、充放電装置１２の電源遮断をする（ステップＳＴ３１）。具体的には、温度監視ユニット１３が、電池２０＋Ｘの特定の部位の温度が上上限Ｕｔ２を超えたこと、又は電池２０＋Ｘの電圧値が上上限Ｕｅ２を超えたことを検出して、電池２０＋Ｘの異常を判定する。温度監視ユニット１３が、安全制御機構１１へ異常信号を送る。安全制御機構１１が異常信号に基づいて、充放電装置１２の電源遮断をする指令信号を充放電装置１２に送る。すると、充放電装置１２の電源が遮断され、電池２０＋Ｘ以外の電池２１、電池２２、電池２３、…、電池２０＋Ｎも、停止し、充放電などの動作を継続しない。   As shown in FIG. 4, the temperature monitoring unit 13 detects an abnormality in the temperature of the battery 20 + X in the thermostatic chamber X for the channel CH X, and the safety control mechanism 11 shuts off the power supply of the charging / discharging device 12 (step ST31). . Specifically, the temperature monitoring unit 13 detects that the temperature of a specific part of the battery 20 + X exceeds the upper upper limit Ut2, or the voltage value of the battery 20 + X exceeds the upper upper limit Ue2, Judge abnormalities. The temperature monitoring unit 13 sends an abnormal signal to the safety control mechanism 11. Based on the abnormal signal, the safety control mechanism 11 sends a command signal for powering off the charging / discharging device 12 to the charging / discharging device 12. Then, the power supply of the charging / discharging device 12 is cut off, and the batteries 21, batteries 22, batteries 23,..., And batteries 20 + N other than the battery 20 + X are also stopped and operations such as charging / discharging are not continued.

その後、ユーザ等が安全や動作の正常性を確認する。この確認後、上上限異常を解除するステップについて説明する。図５に示すように、リセット釦を押し下げる（ステップＳＴ４１）。すると、該当する電池２０＋Ｘの異常が解消されていれば（ステップＳＴ４２：ＹＥＳ）、非常停止がリセットされる。電池２０＋Ｘと、電池２０＋Ｘ以外の電池２１、電池２２、電池２３、…、電池２０＋Ｎとは、再び充放電を開始する（ステップＳＴ４３）。   Thereafter, the user or the like confirms safety and normality of operation. After this confirmation, the step of canceling the upper / upper limit abnormality will be described. As shown in FIG. 5, the reset button is depressed (step ST41). Then, if the abnormality of the corresponding battery 20 + X has been eliminated (step ST42: YES), the emergency stop is reset. The battery 20 + X and the battery 21, battery 22, battery 23,..., Battery 20 + N other than the battery 20 + X start charging / discharging again (step ST43).
