Title:
直列群のバッテリまたはキャパシタのセル充電状態および放電状態の分岐を検出する方法
Document Type and Number:
Japanese Patent JP2011520408
Kind Code:
A
Abstract:
A system for charging a battery includes a battery pack having at least two lithium ion cells. A controller detects a rate of change of voltage with respect to a state of charge (dV/dSOC) of the battery pack based on a calculated dV/dSOC that represents the battery pack as a whole, without calculating dV/dSOC individually on a cell-by-cell basis. Charging is terminated when dV/dSOC reaches a predetermined value.
