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.

How hard is it to protect a lithium-ion battery?

Protecting Your Lithium-Ion Batteries Isn’t So Hard. Sponsored by: Texas Instruments Safety is a primary concern when using lithium-battery technology—here's one approach to implementing the level of protection needed in battery packs for portables.

What are the different types of battery pack protection?

Battery Packs Battery-pack protection comes in two basic types: voltage protection and current protection. Voltage protection uses comparators to monitor individual cell voltages to see how they compare to thresholds that determine an overvoltage (OV) or undervoltage (UV) condition.

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 are lithium-ion and lithium-polymer batteries?

Lithium-ion and lithium-polymer batteries are increasingly finding their way into portable and mobile devices. These highly efficient battery technologies pack more energy into a smaller size than almost any other battery type.

Why do you need a battery protection IC?

That is why we design our battery protection ICs to detect a variety of fault conditions including overvoltage, undervoltage, discharge overcurrent and short circuit in single-cell and multi-cell batteries, so you can enhance the safety of your battery pack.
