Title (EN) LITHIUM-ION ASSEMBLED BATTERY
(FR) BATTERIE ASSEMBLÉE AU LITHIUM-ION
(JA) リチウムイオン組電池
Abstract:
(EN) Provided is a lithium-ion assembled battery having a simple configuration and capable of always automatically correcting the variation in voltage and the variation in capacity among a plurality of unit batteries while suppressing, to the minimum, capacity leakage and the degradation of storage performance associated with the capacity leakage. The lithium-ion assembled battery is provided with a plurality of lithium-ion unit batteries connected in series with each other and a Zener diode connected in parallel with each of the unit batteries, wherein said Zener diode is characterized in that a current of 1/200 or less of the capacity of the unit batteries flows at an average voltage of the unit batteries.
(FR) La présente invention concerne une batterie assemblée au lithium-ion ayant une configuration simple et pouvant toujours corriger automatiquement la variation de tension et la variation de capacité parmi une pluralité de batteries unitaires tout en supprimant, au minimum, la fuite de capacité et la dégradation des performances de stockage associées à la fuite de capacité. La batterie assemblée au lithium-ion est pourvue d'une pluralité de batteries unitaires au lithium-ion connectées en série les unes aux autres et d'une diode Zener connectée en parallèle à chacune des batteries unitaires, ladite diode Zener étant caractérisée en ce qu'un courant inférieur ou égal à 1/200 de la capacité des batteries unitaires circule à une tension moyenne des batteries unitaires.
(JA) 容量漏れ及びそれに伴う保存性能の低下を最小限に抑えながらも、複数の単電池間の電圧バラつきや容量バラつきを常時自動的に補正することが可能な、簡素な構成のリチウムイオン組電池が提供される。このリチウムイオン組電池は、互いに直列接続された複数のリチウムイオン単電池と、単電池の各々に並列接続されるツェナーダイオードとを備え、ツェナーダイオードが、単電池の平均電圧において、単電池の容量の1/200以下の電流が流れることによって特性付けられるものである。
