Helium Charged - Vacuum Test


Double Chamber machine for prismatic battery cell  with central sliding cart for loading/unloading. Principle of measurement: global test in vacuum chamber with helium as tracer gas and  mass-spectrometer analisys.

Machine designed to inspect 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.

Helium Charged - Vacuum Test

The machine provides two vacuum chambers, with manual opening and closing, assembled on a welded and painted steel frame with movable panels. The chambers work alternatively: when one chamber is closed and it’s running the test cycle, the other chamber is open for loading/unloading. The vacuum pumping system is placed behind the chambers. The cabinets containing the electric switchboard and the analysis systems are fixed to the frame, while the pneumatic boards for the distribution of the process gas are fixed to the vacuum chambers. Both chambers are opened automatically towards the centre of the machine, so that the loading/unloading position is the same for both of them and it is protected by optical safety barriers. HMI is made by a touch-screen colour monitor and two remote control boxes (one for each chamber) with the push-buttons and light signals for the operator. The equipment provides separate outlet ports for helium and air discharge and it is suitable to be connected to a helium recovery system.
