PCM (Protection Circuit Module)
Rechargeable lithium-ion batteries, which dominate the secondary battery, are widely used in various applications, including mobile phones, laptops, power tools, and energy storage systems (ESS). However, the chemical instability of lithium-ion cells can pose significant risks, such as fires and explosions, when exposed to air or moisture.
​
To mitigate this, incorporating a PCM into battery packs that utilize lithium-ion cells is critical for ensuring safety and reliability. Our top-quality manufactured PCMs effectively protect against these hazards.
-
Overcharge Protection: Automatically halts charging when the voltage surpasses safe thresholds.
-
Over-discharge Protection: Prevents discharge when the voltage falls below the established sage limit.
-
Overcurrent Protection: Shuts down usage if the current exceeds acceptable operating levels.
