Battery Leak Testing Equipment For Automotive Steel Case Batteries With One Chamber
Application of Battery Leak Testing Equipment:
Leak testing can be performed on the production line using conventional techniques with helium as a tracer gas. Cells can be tested in different stages of the production process: immediately after electrolyte filling and sealing, after formation, or after degassing and subsequent final sealing, and up to the check during the end-of-line testing.
Feature of Battery Leak Testing Equipment:
Depending on the type of cell (button, cylindrical, prismatic or pouch) and its size, special customizations may then be necessary in relation to the dimension and shape of the vacuum chamber, number of cells in the chamber, test time, ...
The picture shows an example of an automatic machine for the leak test for a steel-cased battery, characterized by a rate of 1 cell every 34 second.
In order to prevent contamination of the vacuum chamber, a gross leak test is carried out, in order to discard the batteries with macroscopic defects.
