Battery cabinet helium inspection

What is a battery inspection checklist?

Regular battery inspections assist to ensure optimal performance & safety. Following this checklist makes sure that all important components are evaluated and any necessary steps are performed to keep the system operational. This detailed Battery Inspection Checklist ensures battery performance and safety.

What is a battery inspection?

The first level of inspection involves a thorough visual examination of the battery’s physical condition. This step checks for any mechanical or structural faults that could hinder performance. Mark “OK,” “Not OK,” or “N/A” in the appropriate boxes for each point.

What is a helium test machine?

Machine designed to test complete cells before electrolyte filling and sealing. The same type of machine can be used to check finished cells after filling and sealing, in particular using the helium as tracer gas when it has been filled in the cell with the electrolyte.

What are the new leak test requirements for battery cells?

ty and performance.leak test for battery cellsWith HEV/EV technology comes new leak test requirements for the automotive industry: each single battery cell must be protected, reliab y, against any penetration of humidity and air. The MARPOSS helium vacuum

How can a mass spectrometer detect a battery leak?

The mass spectrometer will detect the presence of helium in the chamber and measure the size of the leakage Depending on the type of cell, it's possible to perform the leak testing of finished battery cells, before or after formation, by tracing of vapor or gases that are already present, or generated inside the cell.

How helium is used in a bombing cell?

The tested cell is firstly introduced into the bombing chamber, filled with high pressure Helium. In presence of a sealing defect in the housing, the helium will enter the cell. The cell is then moved to the vacuum chamber, where the helium will be free to exit from the cell through the same sealing defect.
