Protection Circuit Module (PCM) Functions
  • Overcharge Protection: Cuts off charging circuit when voltage reaches 4.2V-4.25V to prevent cell bulging, fire, or explosion
  • Over-Discharge Protection: Disconnects discharge circuit at 2.5V-2.3V to prevent copper foil dissolution and permanent capacity decay
  • Overcurrent Protection: Detects and shuts down MOS switch when current exceeds safe threshold (e.g., 3A) to prevent overheating
  • Short Circuit Protection: Cuts off circuit within milliseconds during short circuit conditions to prevent fire or explosion
  • Temperature Protection: NTC thermistors limit charging/discharging in extreme temperatures (>60℃) for improved safety
  • Battery Balancing: Active or passive balancing in multi-cell packs ensures consistent voltage across all cells
