Title (EN) CHARGING CIRCUIT
(FR) CIRCUIT DE CHARGE
(JA) 充電回路
Abstract:
(EN) A charging circuit 1 is provided with: a first power source circuit 11 that supplies charging power to secondary batteries B1, B2; a switch SW that controls said supplying of power; and a control device 13 that carries out switching control for the switch SW. The control device 13 detects the voltage difference between the secondary batteries B1, B2 before charging begins, starts a timer and begins serially charging the secondary batteries B1, B2, and, on the condition that the pre-charge voltage difference was at least equal to a first threshold value, when the respective voltage values of the secondary batteries B1, B2 are both at least equal to a second threshold value before the timer ends, the remaining time on the timer is shortened at that point in time, and the serial charging of the secondary batteries B1, B2 is stopped at the earlier of the following two times: when the secondary batteries B1, B2 are both fully charged; or, when the timer ends.
(FR) L'invention concerne un circuit de charge (1) qui est pourvu : d'un premier circuit source d'alimentation (11) qui fournit de l'énergie de charge à des batteries rechargeables (B1, B2) ; d'un interrupteur SW qui commande ladite fourniture d'énergie ; et d'un dispositif de commande (13) qui effectue une commande de commutation de l'interrupteur SW. Le dispositif de commande (13) détecte la différence de tension entre les batteries rechargeables (B1, B2) avant qu'une charge ne commence, lance une minuterie et commence à charger en série les batteries rechargeables (B1, B2), et, à condition que la différence de tension avant charge soit au moins égale à une première valeur seuil, lorsque les valeurs de tension respectives des batteries rechargeables (B1, B2) sont toutes deux au moins égales à une seconde valeur seuil avant que la minuterie ne s'éteigne, le temps restant sur la minuterie est raccourci à cet instant, et la charge en série des batteries rechargeables (B1, B2) est arrêtée au premier des deux instants suivants : lorsque les batteries rechargeables (B1, B2) sont toutes les deux entièrement chargées ; ou lorsque la minuterie s'éteint.
(JA) 充電回路1は、二次電池B1、B2に充電電力を供給する第1電源回路11と、その電力供給を制御するスイッチSWと、スイッチSWの切り替え制御を行う制御装置13と、を備え、制御装置13は、充電開始前に二次電池B1、B2の電圧差を検出し、タイマーを起動して二次電池B1、B2の直列充電を開始し、充電前の電圧差が第1閾値以上であったことを条件として、タイマーが終了する前に二次電池B1、B2の各電圧値が共に第2閾値以上になった場合には、その時点でタイマーの残り時間を短縮し、二次電池B1、B2が共に満充電になったとき、又はタイマーが終了したときのいずれか早い方の時点で二次電池B1、B2の直列充電を終了する。
