Electric heating device, corresponding heating circuit and method for managing the temperature

A heating circuit for an interior of a vehicle, comprising:

• at least one electric heating device having:
• at least one fluid inlet,
• a first fluid outlet,
• a second fluid outlet,
• a first heating element connected to the first fluid outlet, configured to electrically heat, to a first temperature, a portion of the heat transfer liquid that flows through the first outlet,
• a second heating element connected to the second fluid outlet, configured to electrically heat, to a second temperature different from the first temperature, another portion of the heat transfer liquid intended to flow through the second outlet,
• for each heating element, at least one first associated temperature sensor arranged so as to measure the temperature of the associated heating element,
• for each fluid outlet, at least one second associated temperature sensor arranged so as to measure the temperature of the fluid at the associated outlet, and
• a control module for said first and second heating elements,
• wherein the control module comprises at least one processing means for:
• using the temperature information of the first and second temperature sensors;
• and
• generating a command for at least one of the first and second heating elements as a function of the temperature information of the first and second temperature sensors, so as to regulate the temperature of the fluid inside the heating device.
