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
HELIUM TRACING
A complete range of applications for leak testing of different types of battery cells with helium as tracer gas in vacuum chamber.
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.
LEAK TESTING OF BATTERY TRAY & COVER
WITH HELIUM IN ACCUMULATION CHAMBER
Fast and accurate global tests for in-line check in mass production of the perfect sealing of the battery pack components before assembly.
WITH SNIFFING SYSTEMS
When a local test with identification of the leaking points is required, either in off-line repair stations or in mass production.
AIR TESTING METHODS
A complete range of electronics for your leak testing applications based on air testing methods
LEAK TESTING OF COOLING COMPONENTS
TESTING OF CHILLERS BY HELIUM DETECTING SYSTEMS
Leak testing machines to control the perfect sealing of the heat exchangers typically used in the cooling circuits of battery packs for automotive applications.
TESTING OF COOLING PLATES BY HELIUM DETECTING SYSTEMS
Leak testing applications with helium in vacuum chamber for refrigerant gas plates, to detect the smallest leakage rates.
AIR TESTING METHODS
A complete range of electronics for your leak testing applications based on air testing methods
LEAK TESTING OF FULLY ASSEMBLED BATTERY PACK
WITH HELIUM IN ACCUMULATION CHAMBER
Leak testing machines dedicated to the assembly lines of battery packs. Fast, accurate and insensitive to ambient temperature variations.
WITH SNIFFING SYSTEM
When a local test with identification of the leaking points is required, either in off-line repair stations or in mass production.
