    FAQs about The reason why battery packs charge each other

    Why does a large battery pack charge so fast?

    In a huge battery pack like in EVs or solar arrays the cells are distributed over a waste areas and there might be temperature difference among the pack itself causing one cell to charge or discharge faster than the remaining cells causing an imbalance.

    Why does a battery pack always have balanced cells?

So a fresh battery pack will always have balanced cells. But as the pack is put into use the cells get unbalanced due to the following reasons. SOC Imbalance

    What causes a difference in battery voltages?

    A difference in cell voltages is a most typical manifestation of unbalance, which is attempted to be corrected either instantaneously or gradually through by-passing cells with higher voltage. However, the underlying reasons for voltage differences on the level of battery chemistry and discharge kinetics are not widely understood.

    Why do batteries need to be balanced while charging?

    In this respect, the BMS must provide cell balancing capabilities, which is the idea behind intelligent charging. Since the internal impedance of each battery is not exactly identical, series-connected batteries must be balanced while charging in order to preserve their capacity [140 - 142].

    What happens if you overcharge a battery?

    Overcharging and overheating of the battery causes reaction of active components with electrolyte and with each other ultimately causing to explosion and fire. Thermal run-away can be caused merely by overcharging a single cell to voltages above 4.35V. Other cells of the pack will also join the explosive chain reaction if one cell is compromised.
