Classification: CPC H  B  G  Y | IPC G  H

Claim 6:
7. A method for pressurizing or de-pressurizing a battery system comprising the following steps:
providing a container of claim 1;
determining a condition by sensing pressure of the battery cell;
calculating a current state of health (SOH) for the battery system based on the condition and battery metrics;
providing one or more comparison values; and
comparing the one or more comparison values to the current SOH to provide a comparison result; and
determining if a safety condition exists based on the comparison result;
applying a first pressure to the battery system if the comparison result is normal;
applying a second pressure if the comparison result is not normal and no safety conditions exist;
applying a third pressure if the comparison result is not normal and no safety condition exists, and maintenance is required; or
de-pressurizing the battery system if the comparison result is not normal and a safety condition exists.
