La présente invention : permet de déterminer facilement le type d'un élément lorsqu'un élément est fixé à un dispositif de génération d'aérosol ; et permet de commander le fonctionnement du dispositif de génération d'aérosol conformément au type. L'invention concerne une unité d'alimentation (10) pour un dispositif de génération d'aérosol. L'unité d'alimentation (10) comprend : un élément émetteur de lumière (171) qui émet de la lumière vers une partie de réflexion (220) disposée sur une cartouche (200) lorsque l'unité d'alimentation est connectée à la cartouche ou après que l'unité d'alimentation a été connectée à celle-ci ; un élément de réception de lumière (172) qui reçoit la lumière réfléchie par la partie de réflexion ; et une unité de commande qui détermine le type de cartouche sur la base de la lumière reçue par l'élément de réception de lumière.
