The current new energy vehicle battery is a complex mechatronics system, composed of different components.
Some related parts, such as...
> Component size up to 2 meters;
> Battery case, battery pack;
> Heat pipe system;
> The use of electrical and electronic components;
> Parts that can be destroyed in contact with liquids.

Cells are components that undergo complex electrochemical processes, Even the smallest particle impurities that appear during the manufacturing process and reach the components can seriously damage the quality of the battery cell, especially the presence of metal particles.

Batteries naturally involve many problems, such as internal short circuits in batteries..... VDA19.1 Established cleanliness standards have been unable to meet the technical requirements of lithium batteries
> For example, limit particle setting
> Standard analysis of particle size
> Foreign body extraction of powder particles
> Production site environment testing
> Dry particle extraction device

> 1-4 Station cleanliness particle measurement system
> Dry particle extraction system
> Raw material magnetic foreign particle extraction system, etc.
