Battery Management System Overcharge Failure
Thermal behavior and failure mechanism of lithium ion cells during overcharge …
Cells in battery packs are easily overcharged when battery management system (BMS) is out of order, causing thermal runaway. However, the traditional calorimetry could not estimate dynamic overcharging heat release. In this study, commercial LiCoO 2 + Li(Ni 0.5 Co 0.2 Mn 0.3)O 2 /C + SiO x cells are employed to investigate the dynamic thermal …
Study on Thermal Safety of the Overcharged Lithium-Ion Battery

Overcharge
The failure of the battery management system (BMS) to stop the charging process before the upper voltage limit is the ordinary cause of overcharge abuse. The inconsistency within the battery pack determines that the cell with the highest voltage is the first overcharged cell, followed by the others.
