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 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.

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.

Can Daly BMS be used for LiFePO4 batteries?

DALY BMS 16S 60V 30A Lithium ion with balance leads. Charge, Discharge Protection Current, Voltage range are permanently programmed inside BMS and cannot be changed. This is a 16S fixed configuration BMS. It cannot be used for any other battery pack configuration. This BMS also cannot be used for LiFePo4, Li-Metal or LTO batteries.

How does a battery cell Protection Board work?

The battery cells can now receive a charge from a charger. Some devices may pull out too much of a charge in too fast of a short time span. To protect the battery cell and MOS tube, the protection board enacts discharge protection to the cell, turning off the pins and disconnecting the switch tubes.

What happens if a lithium battery reaches 300 Ma?

If the load voltage reaches over 300mA immediately, the voltage pin is turned off and the switch tube is disconnected. This feature helps protect the battery cell. All lithium battery cells, BMS, and protection boards undergo certification. UN/DOT 38.3.5 involves the shipping and transportation of lithium batteries.
