Abstract:
(EN) A control device (2000) having a control unit (2020). The control unit (2020) controls a charging device (20) so as to charge a lithium ion secondary battery (10) by means of the charging device (20). First, the control unit (2020) charges the lithium ion secondary battery (10) by means of the charging device (20) until the voltage of the lithium ion secondary battery (10) reaches a prescribed voltage. Then, the control unit (2020) stops the charging of the lithium ion secondary battery (10) by the charging device (20) until a prescribed time elapses. After this stoppage the control unit (2020) again charges the lithium ion secondary battery (10) by means of the charging device (20). The prescribed time is a time t (minutes) that satisfies the inequality "t ≥ −A+B*x+C*y", where x (g/cm2) is the per-area weight of the negative pole of the lithium ion secondary battery (10), y (g/cm3) is the density of the negative pole, A is a constant between 50 and 70, B is a constant between 500 and 620, and C is a constant between 30 and 36.
(FR) La présente invention concerne un dispositif de commande (2000) doté d'une unité de commande (2020). L'unité de commande (2020) commande un dispositif de charge (20) de manière à charger une batterie secondaire au lithium-ion (10) au moyen du dispositif de charge (20). D'abord, l'unité de commande (2020) charge la batterie secondaire au lithium-ion (10) au moyen du dispositif de charge (20) jusqu'à ce que la tension de la batterie secondaire au lithium-ion (10) atteigne une tension prescrite. Ensuite, l'unité de commande (2020) arrête la charge de la batterie secondaire au lithium-ion (10) par le dispositif de charge (20) jusqu'à ce qu'un délai prescrit s'écoule. Après cet arrêt, l'unité de commande (2020) charge à nouveau la batterie secondaire au lithium-ion (10) au moyen du dispositif de charge (20). Le temps prescrit est un temps t (minutes) satisfaisant l'inégalité "t ≥ −A+B*x+C*y", où x (g/cm2) désigne le poids par zone du pôle négatif de la batterie secondaire au lithium-ion (10), y (g/cm3) désigne la densité du pôle négatif, A désigne une constante entre 50 et 70, B désigne une constante entre 500 et 620, et C désigne une constante entre 30 et 36.
(JA) 制御装置(2000)は制御部(2020)を有する。制御部(2020)は、充電装置(20)を制御することで、充電装置(20)にリチウムイオン二次電池(10)の充電を行わせる。まず制御部(2020)は、リチウムイオン二次電池(10)の電圧が所定電圧になるまで、充電装置(20)にリチウムイオン二次電池(10)の充電を行わせる。その後、制御部(2020)は、所定時間が経過するまで、充電装置(20)にリチウムイオン二次電池(10)の充電を休止させる。そして制御部(2020)は、この休止の後、充電装置(20)にリチウムイオン二次電池(10)の充電をさらに行わせる。上記所定時間は「t≧-A+B*x+C*y」を満たす時間 t[分]である。x[g/cm2] は、リチウムイオン二次電池(10)の負極の目付量を表す。y[g/cm3]は負極の密度である。A は 50 以上 70 以下の定数である。B は 500 以上 620 以下の定数である。C は 30 以上 36 以下の定数である。
