【００１２】
【発明の実施の形態】
以下、添付図面を参照して本発明の実施形態について説明し、本発明の理解に供する。尚、以下に示す実施形態は本発明を具体化した一例であって、本発明の技術的範囲を限定するものではない。
【００１３】
本実施形態は、図１に示すように、二次電池１５と、この二次電池１５を過充電や過放電等から保護する電池保護回路１６と、二次電池１５の電池電圧、充放電電流、電池温度等を検出して動作状態を管理する電池管理回路１７とを備えて構成された電池電源装置１について、その電池特性及び電池管理回路１７の機能を評価する電池電源装置の評価装置について示すものである。
【００１４】
電池電源装置１は、二次電池１５と、電池保護回路１６及び電池管理回路（電池管理手段）１７を構成した回路基板とをパックケース内に収容した電池パックの形態に構成され、二次電池１５は電池保護回路１６を介してＤＣ入出力端子１８に接続される。また、電池管理回路１７は、ファームウエアや製造番号等を記憶する記憶手段と、電池電圧や充放電電流等を検出する検出手段と、電池管理動作を制御すると共に当該電池電源装置１が接続されるコンピュータ等の電子機器との間に通信バス１９を形成するマイコンとを備えて構成されている。
【００１５】
上記構成になる電池電源装置１の電池特性及び電池管理回路１７の機能を評価する評価装置は、図２に示すように、二次電池１５への充電電源となるＤＣ電源３と、二次電池１５の放電用の負荷となる電子負荷（負荷装置）４と、二次電池１５の電圧、電流、温度を測定するデータロガー（電圧測定手段／電流測定手段／温度測定手段）５と、評価対象とする電池電源装置１を収容する恒温槽６と、この恒温槽６を温度制御する電源となる温度制御電源７と、評価動作を制御すると共にデータの計測処理を行うコントローラ（制御手段／データ収集手段）２とを備えて構成されている。
【００１６】
前記コントローラ２は、オペレーションソフトウエアの一例であるＷｉｎｄｏｗｓ９５によって動作するレベルのコンピュータにより構成することができ、評価動作を制御するアプリケーションソフトウエア（評価ソフトウエア）によって自動的に評価動作を実行する。また、コントローラ２には前記ＤＣ電源３、電子負荷４、データロガー５、温度制御電源７をそれぞれ接続するＧＰＩＢ８が設けられる。ＧＰＩＢ８は計測機器制御用のパラレルインタフェースで、ＤＣ電源３、電子負荷４、データロガー５、温度制御電源７それぞれとの間に信号を並列に伝送できる。また、電池電源装置１の通信バス（ＳＭＢｕｓ）に接続するために、ＳＭＢｕｓとＲＳ２３２Ｃとの間の変換器９が設けられ、電池管理回路１７のデータはシリアルインタフェースＲＳ２３２Ｃによりコントローラ２に取り込まれる。
【００１７】
上記構成において、恒温槽６内に評価対象とする電池電源装置１を配置し、電池電源装置１のＤＣ入出力端子１８にＤＣ電源３、電子負荷４、データロガー５を接続し、通信バス１９に変換器９を接続して、評価動作を開始することができる。コントローラ２の評価ソフトウエアを起動して、評価条件を設定するとシーケンスプログラムに従って自動的に評価動作が開始される。
【００１８】
シーケンスプログラムは評価条件に応じて設定され、複数の電流条件での充放電、あるいは複数の温度条件での充放電がなされる。ＤＣ電源３による充電方法、充電電圧、充電電流、充電終止電圧等は評価対象とする電池電源装置１の種類に応じて設定され、コントローラ２の制御によりＤＣ電源３から電池電源装置１に供給される。また、電子負荷４による放電方法、放電電流等についても同様に設定され、コントローラ２の制御により電池電源装置１から電子負荷４に放電がなされる。
【００１９】
この充放電時における充電電流、放電電流、電池電圧はデータロガー５によって測定され、測定データはリアルタイムにコントローラ２に入力される。また、充放電時において電池電源装置１の電池管理回路１７によって検出される充電電流、放電電流、電池電圧は変換器９を通じてリアルタイムにコントローラ２に入力される。従って、コントローラ２において同一の時間軸でデータロガー５によって測定されたデータと電池管理回路１７によって検出されたデータとを比較することができ、電池電源装置１の動作状態を評価することができる。
【００２０】
温度条件による電池電源装置１の動作状態を評価する場合には、コントローラ２により温度制御電源７を制御して恒温槽６の温度を変えて、各温度における充放電時の充電電流、放電電流、電池電圧、電池温度をデータロガー５によって測定し、コントローラ２において電池管理回路１７により検出された充電電流、放電電流、電池電圧、電池温度と比較することにより電池電源装置１の評価がなされる。この温度条件による評価を行うとき、恒温槽６は設定温度になるまでに時間を要するため、恒温槽６の温度が設定温度または設定温度の許容範囲内に落ち着くまで充電または放電を待機するように制御することが望ましい。
【００２１】
上記コントローラ２によるデータのサンプリング周期は、１ｍｓｅｃ〜１０ｍｉｎに設定することができ、電池電源装置１の種類や恒温槽６の温度変化所要時間によって適宜に設定し、取得されたデータは順次コントローラ２内の記憶装置内に格納される。また、サンプリングにより取得したデータと前回取得したデータと比較して、その変化がゼロまたは所定値以下であった場合には、記憶装置へのデータ格納を見送るようにすると、記憶装置に対する負荷を軽減することができる。
【００２２】
また、コントローラ２に対して設定操作を行った後は全て自動で計測動作がなされるので、連続した稼働が可能であり、計測のための専任者を常時置く必要がなく、連続稼働により所要時間を著しく短縮することができる。
【００２３】
図３は、温度条件による評価動作の所要時間の例を示すもので、専任者が１日１２時間労働で手動測定した場合と、実施例構成により自動試験した場合との所要時間を比較している。開発された１件の電池電源装置１に対して３セットの評価作業を実施した場合に、従来の手動試験ではデータ採取のために約５０日必要であり、その間は専任者が専従することになる。これに対して本実施例による自動試験では専任者を置く必要がないため、２４時間稼動が可能であり約２５日の所要時間で評価を完了することができる。
【００２４】
この評価動作により、充放電がなされたときにデータロガー５によって測定される電池電圧、充放電電流、電池温度と、電池電源装置１の電池管理回路１７によって検出される電池電圧、充放電電流、電池温度とが比較されるので、電池電源装置１の動作が評価できる。前記電池管理回路１７は前述したようにマイコンによって構成されているため、そのファームウエアが正常に機能していない場合に比較に不一致が生じる。即ち、ファームウエアにバグがある場合やアウトソーシング開発者のファームウエアの無断変更などを発見することができ、ファームウエアの正規化を図ることができる。
【００２５】
また、図４に示すように、コントローラ２はネットワークＩ／Ｆ１１を設けてＬＡＮ（Ｌｏｃａｌ Ａｒｅａ Ｎｅｔｗｏｒｋ）に接続されたコンピュータに構成することにより、計測場所から任意のネットワーク上にあるコンピュータにデータを伝送することができ、例えば、電池電源装置１の設計部門にデータ伝送して、データ処理、評価結果に基づく設計変更等に利用することができる。
【００２６】
また、ネットワークはＬＡＮだけでなく、インターネット接続による電子メールによってデータを伝送するように構成することもでき、遠隔地へのデータ伝送が可能となる。また、データをハードディスクなどの記憶装置に格納し、格納場所をＷＷＷサイトにリンク公開し、任意の場所からＷＷＷサイトにアクセスしてデータの確認するように構成することもできる。これらの公開されたネットワーク上にデータを伝送する場合には、データの暗号化やパスワードによるアクセス権の許可等のセキュリティ対策を施すことが必要である。
【００２７】
【発明の効果】
以上の説明の通り本発明によれば、電池電源装置の動作状態を評価する作業を自動で行うことができるので、専従者を設けることなく速やかに評価結果を得ることができ、電池電源装置の開発を効率化することができる。また、通信ネットワークを介して評価データを任意場所に伝送することもできる。

[0016]
The controller 2 can be configured by a computer operating at a level of Windows 95, which is an example of operation software, and automatically executes an evaluation operation by application software (evaluation software) that controls the evaluation operation. The controller 2 is provided with a GPIB 8 for connecting the DC power source 3, the electronic load 4, the data logger 5, and the temperature control power source 7. GPIB 8 is a parallel interface for controlling measurement equipment, and can transmit signals in parallel with each of DC power source 3, electronic load 4, data logger 5, and temperature control power source 7. Further, in order to connect to the communication bus (SMBus) of the battery power supply device 1, a converter 9 between the SMBus and RS232C is provided, and the data of the battery management circuit 17 is taken into the controller 2 by the serial interface RS232C.
[0017]
In the above configuration, the battery power supply device 1 to be evaluated is disposed in the thermostatic chamber 6, the DC power supply 3, the electronic load 4, and the data logger 5 are connected to the DC input / output terminal 18 of the battery power supply device 1. The converter 9 can be connected to and the evaluation operation can be started. When the evaluation software of the controller 2 is activated and the evaluation conditions are set, the evaluation operation is automatically started according to the sequence program.
[0018]
The sequence program is set according to the evaluation conditions, and charging / discharging under a plurality of current conditions or charging / discharging under a plurality of temperature conditions is performed. The charging method, charging voltage, charging current, charging end voltage, etc. by the DC power source 3 are set according to the type of the battery power source device 1 to be evaluated, and are supplied from the DC power source 3 to the battery power source device 1 under the control of the controller 2.

Further, the network can be configured to transmit data not only by LAN but also by e-mail via Internet connection, and data transmission to a remote place becomes possible. It is also possible to store data in a storage device such as a hard disk, link the storage location to the WWW site, and access the WWW site from any location to check the data. When data is transmitted over these open networks, it is necessary to take security measures such as data encryption and permission of access rights using passwords.
