中文摘要

针对锂电池组内因老化差异导致的SOC估计难题,本文提出了一种放电模式识别(DMI)方法。该方法通过简化处理流程,实现了在宽寿命周期内对串联电池组SOC的精确在线估计,有效提升了储能系统在全生命周期内的运行精度与可靠性。

English Abstract

Lithium-ion batteries are widely used in energy storage nowadays. However, differences caused by aging among in-pack cells are inevitable, which makes accurate state-of-charge (SOC) estimation for packs still challenging. In this article, a novel discharge mode identification (DMI) method for series-connected battery pack online SOC estimation is proposed. The DMI method simplifies the process of ...
