Claim 16:
17. A vehicle comprising:
an electrically drivable assembly;
a battery cell configured to supply the assembly with electrical energy in a controllable fashion; and
a control device configured to control the operation of the assembly and/or of the battery cell, the control device being configured to:
detect a value of a measured variable for determining an external temperature of the battery cell,
determine an internal temperature of the battery cell by detecting an electrical impedance of the battery cell, and
determine a value of an operating temperature of the battery cell from the external temperature and/or from the internal temperature,
wherein at least in a first operating state of the battery cell the internal temperature of the battery cell
is determined less frequently if the value of the determined external temperature, the internal temperature and/or the operating temperature of the battery cell is in a predefined first safe range, and
is determined more frequently if the value of the determined external temperature, the internal temperature and/or the operating temperature of the battery cell is outside the predefined first safe range.
