PCM (Protection 1Circuit Module)

• PCM is a circuit device that protects abnormal behavior including heat generation, ignition and explosion of battery pack by measuring and blocking voltage and current when charging and discharging Li-Ion batteries.

PCM Features

• 1) Protection of Over-charging

  : Blocking from overcharging than normal voltage of battery cells

• 2) Protection of Over-discharging

  : The ability to block discharge below the voltage of battery cells

• 3) Protection of Over-currents and Short Circuits

  : The ability to block charging and discharging from flowing above a certain current

• ※ Application

  - Mobile, Foldable, Cradle, Watch, VR / AR

SM (Smart Module) / BMU (Battery Management Unit)
