The appearance structure and detailed functions of the battery protection board of the twisted car

by:CTECHi     2021-08-07

With the continuous advancement of technology and the improvement of people’s living standards, more and more electric vehicles have appeared, and the newly developed electric twisting car is also on the stage. Not only is it so popular that it is so 'hotMoreover, the recent explosions in foreign countries have made the Twisted Cars become the focus of 'hotPeople are concerned about the safety of the water surface. Therefore, it is extremely urgent to understand the appearance structure and detailed functions of the battery protection board of the twisted car. Let’s study with everyone today!

Appearance structure:

1) The PCBA board surface is painted with a three-proof paint with high corrosion resistance, high water permeability resistance, and high impedance ESD.

2) The front side is riveted with a high-efficiency aluminum heat sink of equal area, and the back side is pasted with high tenacity barley paper to prevent the solder feet from piercing the battery pack.

Detailed description of appearance and size diagram function:

1) Adopt Hongkang protection IC, HY2120CB program (Houyi MOS).

2) Suitable for lithium batteries with different chemical properties, such as lithium ion, lithium polymer, lithium iron phosphate, etc.

3) Strong load capacity, continuous discharge current 10A, using high withstand voltage, low on-resistance power MOSFET.

4) Overcharge protection, over discharge protection with typical voltage detection methods, and hardware overload and short circuit protection.

5) Effectively protect the battery pack when the external load is accidentally short-circuited, and the internal resistance of the protection board becomes larger after the MOS on the protection board is damaged, and the burning caused by continued discharge and overheating.

6) The short-circuit protection performance is stable and reliable, and the long-term load short-circuit will not affect the protection board and the battery core.

7) Very low power consumption, the current consumption of the whole machine is less than 80uA.
