Abstract
A method for monitoring a battery cell is provided. The method measures a first value corresponding to a pressure inside the battery cell. The method also determines a second value on the basis of the first value. The second value corresponds to a temperature of the battery cell. The method monitors the battery cell on the basis of the second value. It is possible to determine whether the battery cell is in a fault-free state or in a state which is faulty, problematic, or critical.
