Electric vehicle and method of operating the electric vehicle

An electric vehicle comprising:

• a coolant circuit configured for primary coolant to flow therethrough;
• at least one constituent for a drive of the electric vehicle;
• a tank configured to hold cryogenic coolant;
• a control unit;
• and
• an evaporator heat exchanger unit configured to be fluid-mechanically connected to the tank and to be connected to the control unit,
• wherein the at least one constituent for the drive of the electric vehicle and the evaporator heat exchanger unit are fluid-mechanically integrated into the coolant circuit, and
• wherein the control unit is configured to carry out a method comprising:
• detecting an extreme operating situation or an imminent extreme operating situation of the electric vehicle requiring a temperature-induced power limitation of the at least one constituent for the drive of the electric vehicle or a temperature-induced power reduction of the at least one constituent for the drive of the electric vehicle;
• and
• evaporating the cryogenic coolant in the evaporator heat exchanger unit, such that a temperature of the primary coolant is maintained or lowered below a threshold value, such that the power limitation or the power reduction of the at least one constituent for the drive of the electric vehicle is suppressed.
