AN ARRANGEMENT AND A METHOD FOR COLLECTING GAS FROM A BATTERY CELL

Patentradars sammanfattning

TRATON AB's patent describes a gas-collection arrangement comprising two threadably engageable parts: a first part with a cover portion that forms a sealed chamber against the battery cell surface, and a second part bearing a hollow needle or drill fixed to a bottom wall member. Screwing the second part into the first part advances the hollow needle in a controlled, gradual manner to puncture the battery cell—preferably at its safety vent—while the enclosed chamber and multiple sealing rings prevent gas leakage to the surrounding atmosphere. The arrangement supports coupling to external gas analysis equipment via a swivel connector, enabling both post-mortem and in-operando gas analysis.
