Abstract
A method comprises determining a first pressure increase in an electrochemical energy storage unit based on a first repetition rate, detecting that the first pressure increase has exceeded a first threshold value, determining a second pressure increase in the energy storage unit based on a second repetition rate, the second repetition rate being greater than the first repetition rate, detecting that the second pressure increase exceeds a second threshold value, and outputting a signal to a control unit based on detecting that the second pressure increase has exceeded the second threshold value.
