Leak Testing
of Battery Systems

 The verification of a perfect sealing is a crucial operation for the manufacturing process of all the components of battery systems

Marposs can provide a wide range of standard products and customized applications for the leak testing of battery systems along the complete manufacturing chain. From checking the sealing on the cell housing to the leak testing of the finished battery cell. From the verification of the components of the battery pack (trays, frames, covers, ...) and of the refrigeration circuit (chillers, cooling plates, ...) to the End-of-Line sealing test on the fully assembled pack and the cooling circuit.

LEAK TESTING OF BATTERY CELLS

LEAK TESTING OF BATTERY CELLS

 HELIUM TRACING

A complete range of applications for leak testing of different types of battery cells with helium as tracer gas in vacuum chamber.

More Info

 

ELECTROLYTE TRACING

Automatic machines for leak testing in mass production of totally sealed battery cells. Application of direct tracing of electrolyte vapors method, when adding an external tracer gas in the cell is not a feasible option.
