摘要

串联或并联的电池配置可以在每个电池上有不同的电压。电池组中最弱的电池可能比其他电池承受更大的压力,因此它将成为损坏最快的电池。本研究将在牵引驱动应用的电池组中找到能量最低的电池。采用直接测量法对充放电过程进行了最弱电池的识别和分析。结果表明,最弱的电池单元位于电池组的中部。最弱的电池电压为2.75 V,健康电池电压为2.9 V。

The Weakest Cell Identification in Li-Ion battery packs using Discharging Technique Performance
The battery configuration in series or parallel connection can have a different voltage on each cell. The weakest cell in the battery pack could have more stress than other cells so that it will become the fastest damage. This research will find the lowest energy cell in the battery pack for traction drive application. The identification and analysis of the weakest cell is performed on the charging and discharging process with direct measurement. The result shows that the weakest cell located in the middle of the battery pack. The weakest cell have 2.75 V and the health battery cell has 2.9 V.
