6 FAQs about [Lithium battery pack protection board power calculation]

How to protect a lithium battery?

Use special lithium battery protection chip, when the battery voltage reaches the upper limit or lower limit, the control switch device MOS tube cut off the charging circuit or discharging circuit, to achieve the purpose of protecting the battery pack. Characteristics: 1. Only over-charge and over-discharge protection can be realized.

What is a battery protection board?

Hardware-type protection board: Use special lithium battery protection chip, when the battery voltage reaches the upper limit or lower limit, the control switch device MOS tube cut off the charging circuit or discharging circuit, to achieve the purpose of protecting the battery pack. Characteristics: 1.

Why is precision important for LiFePO4 battery pack applications?

How accurate is a LiFePO4 battery pack?

Good measurement accuracy is always required, especially the cell voltage, pack current, and cell temperature. Precision is necessary for accurate protections and battery pack state of charge (SoC) calculations. This is especially true for LiFePO4 battery pack applications because of the flat voltage.

What is the primary protection on a battery pack?

It contains both primary and secondary protections to ensure safe use of the battery pack. The primary protection protects the battery pack against all unusual situations, including: cell overvoltage, cell undervoltage, overtemperature, overcurrent in charge and discharge, and short-circuit discharge.

What happens if a lithium battery is used in pack?

When the lithium battery is used in PACK, it is more likely to over-charge and over-discharge, which is caused by the consistency difference of the cell. If the charging and discharging process is not properly controlled, it will be further increased, resulting in the phenomenon of over-charging and over-discharging of part of the cell.
