BYS345_SP8K24-TB & Special 30V Guide

So the stability of the tube is inseparable from the manufacturing process, and poor workmanship may result in the inconsistency of the parameters of these small tubes. Their various switching actions are almost the same. Of course, when they burn out, there must be a small tube that can't bear it first.

The power mos used on electric vehicles is a three-dimensional structure. Low-power mos is a planar structure. The mos tube we have seen is actually composed of thousands of small mos tubes in parallel. You may think that one or a few bad moss should easily appear in thousands of small mos. In fact, it is not that easy. , the current manufacturing process basically guarantees the high consistency of various parameters of these small units.

The functions of the MOS tube in the protection board are: 1. Detect overcharge, 2. Detect over-discharge, 3. Detect over-current during charging, 4. Detect over-current during discharge, 5. Detect over-current during short circuit.

The battery cell is equivalent to the heart of the lithium battery, and the lithium battery protection board is mainly composed of a protection chip (or management chip), a MOS tube, a resistor, a capacitor, and a PCB board.
