Electrically heated aerosol-generating system

A portable device of an electrical system, wherein the portable device is an electrically heated aerosol-generating device configured to receive an aerosol-generating substrate, comprising:

• a heating element;
• a rechargeable power supply configured to power the heating element;
• a temperature sensor configured to sense an ambient temperature adjacent the device;
• and
• a controller configured to control a supply of power from the rechargeable power supply to the heating element in dependence on the ambient temperature adjacent the device,
• wherein:
• when the ambient temperature adjacent the device is within a pre-determined temperature range, the controller is configured to provide power to the heating element, and
• when the ambient temperature adjacent the device is below a lower end of the pre-determined temperature range, and when the ambient temperature adjacent the device is above a higher end of the pre-determined temperature range, preventing power being supplied to the heating element.

A method of controlling an electrically heated aerosol-generating device configured to receive an aerosol-generating substrate, the device comprising a rechargeable power supply and at least one electrical heating element, the method comprising:

• monitoring an ambient temperature adjacent the device;
• and
• providing power to the at least one electrical heating element from the rechargeable power supply in dependence on the ambient temperature adjacent the device,
• wherein:
• when the ambient temperature adjacent the device is within a pre-determined temperature range, providing power to the at least one electrical heating element;
• and
• when the ambient temperature adjacent the device is below a lower end of the pre-determined temperature range, and when the ambient temperature adjacent the device is above a higher end of the pre-determined temperature range, preventing power being supplied to the at least one electrical heating element.
