What is a lithium battery protection board?
A lithium battery protection board typically includes various essential components like voltage regulators, transistors, resistors, and microcontrollers. 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.
What are the components of a lithium-ion battery pack?
In the lithium-ion battery pack, there are the main electronic modules: the batteries (cells) connected in groups in parallel and series, the cell contact system, and the BMS (battery management system). The BMS is the brain of the battery pack.
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.
What is a battery protection board?
A battery protection board safeguards the battery from overcharging, over-discharging, overcurrent, and short circuits, which could otherwise damage the battery and reduce its lifespan. Here's a guide on how to select the best protection board for your lithium batteries. 1. Determine the Battery Type and Parameters
What is a lithium battery management system (BMS)?
These boards are engineered to provide monitoring and protection functions for low-voltage lithium batteries. For high-voltage lithium batteries, a more comprehensive battery management system (BMS) is typically used, which offers a more nuanced and comprehensive monitoring 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:
