Poor pack design or poor battery management system (BMS) design can also result in some cells being overcharged. Overcharging is the most dangerous electrical abuse scenario, as it results in far more energy being pumped into the cell than the cell is designed to accommodate. If this leads to cell failure, the extra energy is released through a fire or explosion. Causes of lithium-ion cell ...
