Abstract
(EN)
If, after a control unit (6) has executed a first monitoring process, a prescribed condition relating to whether or not a response signal or a notification signal has been received by the control unit is matched, the control unit executes a second establishment process to re-establish communication with each of a plurality of battery units (21 to 2n), by retransmitting a recognition scan signal to each of the plurality of battery units, and receiving response signals transmitted from the battery units that received the recognition scan signals, and after executing the second establishment process, executes a second monitoring process to monitor the state of battery modules (31 to 3n) included in the battery units with which communication has been re-established by means of the second establishment process.
(FR)
Si, après qu'une unité de commande (6) a exécuté un premier processus de surveillance, une condition prescrite concernant le fait que oui ou non un signal de réponse ou un signal de notification a été reçu par l'unité de commande est mise en correspondance, l'unité de commande exécute un second processus d'établissement pour rétablir une communication avec chaque unité d'une pluralité d'unités de batterie (21 à 2n), par retransmission d'un signal de balayage de reconnaissance à chacune de la pluralité d'unités de batterie, et réception de signaux de réponse transmis par les unités de batterie qui ont reçu les signaux de balayage de reconnaissance, et après l'exécution du second processus d'établissement, exécute un second processus de surveillance pour surveiller l'état des modules de batterie (31 à 3n) inclus dans les unités de batterie avec lesquelles la communication a été rétablie au moyen du second processus d'établissement.
(JA)
制御ユニット(6)は、第1監視処理の実行後、制御ユニットにおける応答信号、又は通知信号の受信の有無に関連する所定の条件に合致した場合に、複数のバッテリユニット(21~2n)各々に対して認識スキャン信号を再送信し、認識スキャン信号を受信したバッテリユニットから送信された応答信号を受信することで、複数のバッテリユニット各々との通信を再度確立する第2確立処理を実行し、第2確立処理の実行後、第2確立処理により通信が再度確立されたバッテリユニットに含まれるバッテリモジュール(31~3n)の状態を監視する第2監視処理を実行する。
