  • Method and device for determining an operating temperature, operating method for a battery cell, control unit for a battery cell, and working device
    Patent number: 11951866
    Abstract: A method for determining an operating temperature of a battery cell in which (i) a value of a measure variable for determining an external temperature of the battery cell is detected, (ii) an internal temperature of the battery cell is determined by detecting an electrical impedance of the battery cell, and (iii) a value of the operating temperature of the battery cell is determined from the external and/or the internal temperature. The internal temperature of the battery cell in a first operating state of the battery cell is determined more frequently when the value of the determined external temperature, the internal temperature and/or the operating temperature lies within a predefined first safe range, and is determined less frequently when the value of the determined external temperature, the internal temperature and/or the operating temperature lies outside the predefined first safe range.
