  • the invention relates to a hybrid-powered aerosol-generating device.
  • non-replaceable electrical power sources e.g., a lithium-ion secondary battery fixed inside device. Internally to each of these devices, the power source supplies electrical power to a heater for generating aerosol to be inhaled by a user of the device.
  • a non-replaceable electrical power source has several advantages, including:
  • the design of the aerosol-generating device is simpler, since it is not necessary to have an opening and releasable electrical connection suitable for the user to replace the current electrical power source when discharged with a new one;
  • each aerosol-generating device avoids that the manufacturer of the device has to ensure safety of a replacement operation to be performed by the user and to control of the type of the newly installed electrical power source;
  • the unit cost price of the aerosolgenerating device can be lower
  • the manufacturer of the aerosol-generating device can control the quality of the power source that is used because it is enclosed initially within the device.
  • the dimensions of the electrical power supply system should be small enough for being compatible with those of the aerosol-generating device;
  • any replacement operation to be performed by the user of the aerosolgenerating device should be safe.
  • one object of the present invention consists in providing a new aerosol-generating device which addresses the above-listed issues.
  • An additional object of the present invention consists in maintaining short heating times for delivering aerosol although no non- electrical power source is used, but allowing implementing a rechargeable electrical power source having reduced energy storage capacity.
  • a first aspect of the present invention proposes an aerosol-generating device that comprises internally to a casing of this aerosol-generating device:
  • a heater adapted for generating aerosol from an aerosol-generating substrate when supplied with electrical power
  • a rechargeable electrical power source connected for supplying a first electrical power to the heater
  • a power management system configured for controlling supply of electrical power to the rechargeable electrical power source and to the heater.
  • the aerosol-generating device of the invention combines a rechargeable electrical power source and at least one fuel cell reactor unit, it is said hybrid-powered.
  • This hybrid structure avoids implementing a non- rechargeable electrical power source and allows using a rechargeable electrical power source which has reduced energy storage capacity.
  • this rechargeable electrical power source can be recharged from the at least one fuel cell reactor unit internally to the aerosol-generating device.
  • the overall energy storage means that are implemented, comprised of the rechargeable electrical power source and the hydrogen source can be of small size thanks to the high energy concentrations which are provided by existing hydrogen storage technologies.
  • the power management system is configured for, during a use session of the aerosol-generating device, first activating supply of the first electrical power from the rechargeable electrical power source to the heater according to a first mean power value, and then activating supply of a second electrical power from the fuel cell assembly to the heater according to a second mean power value, the first mean power value being higher than the second mean power value.
  • the rechargeable electrical power source has sufficient output power capacity to produce initial heating of the aerosol-generating substrate within a short duration, and continuing heating with electrical power from the fuel cell assembly allows keeping enough energy in the rechargeable electrical power source for a next power supply to the heater from this rechargeable electrical power source if required before next recharge operation.
  • the invention combines the respective advantages of the rechargeable electrical power source, i.e. high output power value, and of the fuel cell assembly, i.e. high energy storage capacity, optimally for allowing rapid aerosol availability for vaping, in particular for a first puff after the aerosol-generating substrate has been heated-up from ambient temperature.
  • fuel cells tend to be degraded when large current outputs, so this allocation among the rechargeable electrical power source and the fuel cell assembly may also lead to prevent fuel cell degradation.
  • the power management system may be further configured so that supplying the heater with the first electrical power from the rechargeable electrical power source is limited to a pre-heating duration before a first puff is drawn through the aerosol-generating device in the use session. It is further configured so that supplying the heater with the second electrical power from the fuel cell assembly corresponds to a vaping duration subsequent to the preheating duration.

Abstract

Un dispositif de génération d'aérosol (100) comprend une source d'alimentation électrique rechargeable (2) et au moins une unité de réacteur à pile à combustible (31-1, 31-2,...) combinées entre elles pour fournir de l'énergie électrique à un dispositif de chauffage (20) du dispositif. Un système de gestion de puissance (1, 7) active d'abord l'alimentation d'une première puissance électrique (HTR-PW1) entre la source d'alimentation électrique rechargeable et le dispositif de chauffage, puis active l'alimentation d'une seconde puissance électrique (HTR-PW2) entre ladite unité de réacteur à pile à combustible et le dispositif de chauffage. Une première valeur de puissance moyenne de la première puissance électrique est supérieure à une seconde valeur de puissance moyenne de la seconde puissance électrique. Une telle gestion de puissance combine un temps de préchauffage souhaité court, tel qu'autorisé par la puissance de sortie élevée de la source d'alimentation électrique rechargeable, avec une capacité de stockage d'énergie élevée, telle qu'autorisée en utilisant un ensemble pile à combustible.
