Do lithium batteries need a Protection Board?
Protection boards for lithium batteries offer monitoring protection. Low-voltage lithium batteries require a protection board. When using high-voltage lithium batteries, a battery management system (BMS) is typically chosen since these systems contain more functions for monitoring the state of the battery pack.
What is a lithium battery protection circuit?
The protection circuit ensures the voltage does not exceed the safe limits set by the manufacturer. For example, a common lithium-ion battery operates between 3.0V and 4.2V per cell. Exceeding these limits can lead to serious safety risks like overheating, leakage, or even fires. A typical lithium battery protection circuit includes:
Why do lithium batteries need a PCB board?
This boom brings with it the necessity for reliable protection circuits, ensuring that lithium batteries are safe, efficient, and durable. One key component in this protection system is the battery PCB (Printed Circuit Board) board, which plays a crucial role in the operation and safety of lithium batteries.
How do I protect my battery pack?
Make sure your BMS is enabled and perform this function properly to get the most out of your battery pack. The over-current protection function is a key safety feature of the BMS. The OCP will cut off the current if it exceeds the programmed limit, which helps protect the battery and its surrounding components from damage.
How much short circuit protection should a lithium battery have?
Most lithium batteries have a short circuit protection setting of around 200-300mA. This is usually plenty to protect the battery from damage, but if you are using high-powered devices that can draw more current, you may want to increase the short circuit protection to 500mA or more.
What does a battery protection setting do?
This protection setting kicks in when the lithium battery is discharged below a certain voltage level, typically between two and three volts per cell. When this occurs, the battery management system will stop discharging the battery any further to prevent it from being damaged.
