Protection Circuit Module (PCM) Features
Overcharge Protection
Automatically cuts off charging circuit when voltage exceeds safe limits (4.25V-4.3V) to prevent electrolyte decomposition and thermal risks.
Over-discharge Protection
Disconnects discharge path when voltage drops below preset limits (2.5V-3.0V) to protect electrode materials and maintain capacity.
Overcurrent & Short-circuit Protection
Monitors circuit current and cuts off within milliseconds for overcurrent conditions, microseconds for short-circuit events.
Temperature Protection
Integrated NTC thermistors monitor battery temperature, blocking charging/discharging outside safe ranges to prevent damage.
Balancing Function
Maintains voltage consistency between cells in multi-cell packs, optimizing overall capacity and lifespan.
Applications
- Smart Wearable Devices (bracelets, watches, fitness trackers)
- Bluetooth Wireless Devices (TWS earphone cases, speakers, receivers)
- Portable Detection Instruments (thermometers, detectors, multimeters)
- Smart Home Accessories (door lock backup, wireless doorbells, sensors)
- Mini Flashlights & Emergency Power Banks
- Portable Voice Recorders & Translator Pens
