4 Frequently Asked Questions about “40v lithium battery pack protection board”

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 lithium battery protection circuit board?

The lithium battery protection circuit board uses a highly integrated intelligent lithium battery protection circuit board, integrated chip, performance is better than the cover panel consisting of discrete chips.

Can you get a Protection Board with a custom battery pack?

You can also obtain custom-built protection boards with your custom battery packs. This arrangement is ideal since the battery manufacturer will have a greater understanding of the protection needs of the custom pack that they design for the customer. So, the protection board would cater to these design requirements.

What is the main function of a battery protection board?

The main function of the protection board is to monitor the state of charge (SoC), temperature, voltage, current, and state of health (SoH) of the battery pack. The MOS is controlled by the control IC. The MOS is always turned on during normal functions.
