10 / 50
This device is a battery leak detector that allows you to non-destructively check for
leaks, both on hard battery cells and pouch cells.
The device consists of a gas detection system, an optionally available control unit and
an optionally available vacuum test chamber.
For this purpose, the test object is placed in the test chamber and the chamber is
closed.
One or more test chambers are connected to the device at the same time.
After closing the test chamber*, the measuring process is started and the test
chamber is evacuated. In the case of customer test chambers and INFICON test
chambers (optionally available), the customer activates the measuring process via an
interface.
In case of leakage of the test object, the escaping electrolyte evaporates through the
evacuation process.
The evaporated solvent components of the escaping electrolyte are fed to the Gas
Detection Unit and are analyzed for DMC or deviating solvents.
* Optional accessories
The Gas Detection Unit works under high vacuum, i.e., the pressure in the quadrupole
mass spectrometer must always be less than 5 x 10
by the turbomolecular pump with the support of an optionally available diaphragm
pump.
Components of the device:
• High vacuum pump system
• Inlet system for the gas flow
• electrical and electronic sub-assemblies for electrical power supply and signal
processing
The optionally available CP7 enables monitoring of the measurement and diagnosis
with the touch display. The measuring process is controlled by the system itself. The
pump is are used to evacuate the measuring chamber to the desired target pressure.
A valve control system adapted to the measurement sequence allows the analysis gas
to be fed to the Gas Detection Unit.
