A battery protection circuit is an essential component in any battery-powered device to ensure the safe operation and longevity of the battery.
This circuit monitors and regulates the battery's operating parameters, such as voltage, current, and temperature, to prevent damage caused by overcharging, over-discharging, or short-circuiting.
Key Functions:
Overcharge Protection: Prevents the battery from exceeding its maximum charge voltage, which could lead to overheating, swelling, or even explosion.
Over-Discharge Protection: Stops the battery from discharging below its minimum safe voltage, which can cause irreversible capacity loss or damage to the battery's internal chemistry.
Overcurrent Protection: Limits the current flow to avoid excessive heat generation or damage to the connected components.
Short-Circuit Protection: Instantly disconnects the battery in case of a short circuit to prevent severe overheating or fires.
Temperature Monitoring: Shuts off the circuit if the battery temperature exceeds a safe limit.
