Title (EN) CHARGING DEVICE AND CHARGING METHOD
(FR) DISPOSITIF DE CHARGE ET PROCÉDÉ DE CHARGE
(JA) 充電装置及び充電方法
Abstract:
(EN) A charging device (1) equipped with a battery voltage detection unit (15), a constant-current source (12), and a control unit (11). The battery voltage detection unit (15) detects the battery voltage of a secondary battery (BT). The constant-current source (12) supplies charging current to the secondary battery (BT). The control unit (11) calculates a battery residual capacity ratio from the battery voltage detected by the battery voltage detection unit (15), calculates a charging amount from the battery residual capacity ratio and the actual capacity of the secondary battery BT, calculates a chargeable time from the current time and a scheduled charging completion time that has been set, and sets the current value for the charging current so as to obtain a full charge within the chargeable time from the charging amount.
(FR) L'invention concerne un dispositif de charge (1) équipé d'une unité de détection de tension de batterie (15), d'une source de courant constant (12) et d'une unité de commande (11). L'unité de détection de tension de batterie (15) détecte la tension de batterie d'une batterie rechargeable (BT). La source de courant constant (12) fournit un courant de charge à la batterie rechargeable (BT). L'unité de commande (11) calcule un taux de capacité résiduelle de batterie à partir de la tension de batterie détectée par l'unité de détection de tension de batterie (15), calcule une quantité de charge à partir du taux de capacité résiduelle de batterie et de la capacité réelle de la batterie rechargeable BT, calcule un temps de charge possible à partir de l'heure actuelle et d'une heure d'achèvement de charge planifiée qui a été réglée, et règle la valeur de courant pour le courant de charge de manière à obtenir une charge complète dans le temps de charge possible à partir de la quantité de charge.
(JA) 充電装置(1)は電池電圧検出部(15)、定電流源(12)、及び、制御部(11)を備える。電池電圧検出部(15)は二次電池(BT)の電池電圧を検出する。定電流源(12)は二次電池(BT)に充電電流を供給する。制御部(11)は、電池電圧検出部(15)により検出された電池電圧から電池容量残存率を算出し、電池容量残存率と二次電池BTの実容量とから充電量を算出し、設定された充電完了予約時刻と現在の時刻とから充電可能な時間を算出し、充電量から充電可能な時間内に満充電となるように充電電流の電流値を設定する。
