    摘要: An electronic device includes a memory storing a program including instructions, a battery, a charger configured to charge the battery, a power circuit configured to provide power to the charger, and controller. The instructions, when executed by the controller, cause the electronic device to identify a first input current and a first input voltage to be input into the charger, based on information on a target charging power for the battery. The instructions, when executed by the controller, cause the electronic device to control the power circuit such that, based on power provided from an external device, the first input voltage and the first input current are provided to the charger. The instructions, when executed by the controller, cause the electronic device to control the charger to provide charging power corresponding to the target charging power to the battery based on power provided from the power circuit. The instructions, when executed by the controller, cause the electronic device to, while the battery is charged based on the charging power provided from the charger, provide, based on identifying a decrease of an input voltage of the charger to a reference voltage or lower, a request to the external device for increasing the input voltage of the charger to a voltage greater than the first input voltage.

    摘要: Die Erfindung betrifft ein Verfahren zur Fertigung einer Lithiumionen-Batteriezelle, insbesondere Batteriepouchzelle, mit einem Formationsprozess, in dem die Batteriezelle einem Erstladevorgang unterworfen wird, in dem sich Lithiumionen in Aktivmaterial (3, 5) der zumindest einen Anode (A) der Batteriezelle einlagern, und zwar unter Bildung einer SEI-Grenzschicht (9) an der Grenzfläche zum Elektrolyt (E) sowie unter Gasbildung (12), wobei beim Erstladevorgang die Batteriezelle in einen Ladestromkreis (LK) geschaltet ist und mit Gleichstrom geladen wird. Erfindungsgemäß ist der Erstladevorgang in einzelne Ladephasen (L) unterteilt, in denen sich jeweils eine SEI-Teilschicht (10) mit feinkörnigem Gefüge ausbildet. Die einzelnen Ladephasen (L) sind von Nichtladephasen (N) unterbrochen, in denen keine SEI-Bildung erfolgt, so dass die nach dem Erstladevorgang gebildete SEI-Grenzschicht (9) aus den übereinandergeschichteten SEI-Teilschichten (10) aus feinkörnigem Gefüge besteht, das eine Lithiumionen-Mobilität in der SEI-Grenzschicht (9) unterstützt.
