Title (EN) CHARGING DEVICE AND CHARGING METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE CHARGE
(JA) 充電装置及び充電方法
Abstract:
(EN) Provided is a charging device for charging a lithium ion secondary battery 30 on the basis of at least a constant voltage method. In this charging device, at a time point prior to charging at a constant voltage or during charging at a constant voltage, a current pulse having a peak current value i1 that is greater than the charging current value i0 at said time point is applied at least once.
(FR) L'invention concerne un dispositif de charge pour charger une batterie secondaire au lithium-ion 30 sur la base d'au moins un procédé à tension constante. Dans ce dispositif de charge, à un instant précédant la charge à une tension constante ou pendant la charge à une tension constante, une impulsion de courant ayant une valeur de courant de crête i1 qui est supérieure à la valeur de courant de charge i0 audit instant est appliquée au moins une fois.
(JA) リチウムイオン二次電池30を、少なくとも定電圧方式に基づき充電する充電装置が提供される。かかる充電装置では、定電圧にて充電を開始する前に、又は、定電圧にて充電を行っている間に、その時点での充電電流値i0よりも大きなピーク電流値i1を有する電流パルスが、少なくとも1回、印加される。
