Battery protection PCB circuit board

The basic parameters of the battery protection PCB circuit board are as follows:

Number of layers: double-sided FR4 board with copper embedded

Material: FR4 plus copper block

Plate thickness: 3.1MM plus\/-10 percent

Surface copper thickness: 1OZ

Solder mask color: blue

Character color: white

Surface treatment: Au:1u

PCB circuit board size: 135120mm

Battery protection PCB circuit board is a special circuit board with copper substrate PCB embedded in FR4 base material. Some components of this circuit board need to pass high current, and the pads that need to pass high current must be directly made on the copper substrate. The copper base needs to be treated accordingly before pressing.

The function of the battery protection PCB circuit board:

1. Overcharge voltage protection: prevent the charging voltage from being higher than the battery voltage, resulting in battery function failure, resulting in safety hazards and accidents;

2. Over-discharge voltage protection: In order to avoid safety accidents or shorten the life of the battery, it is necessary to prevent and protect the battery from over-discharge;

3. Overcurrent protection: limit the current through the battery and protect the PCB circuit board;

4. Short-circuit protection: avoid battery short-circuit causing safety accidents;

5. Temperature control switch: protect the board and avoid potential safety hazards caused by excessive temperature of the battery pack

Application fields of battery PCB circuit board:

The power battery protection PCB circuit board is mainly used in the field of electric motorcycles and electric vehicles.
