Aerosol Generation Device Power System

An aerosol generation device includes a power system and a controller. The power system includes a supercapacitor moduleand a battery module, and is connectable to an external power source. The controller is configured control a pulse-charging regime of the power system by controlling a first power flow from the external power source to the power system to cyclically switch the first power flow between charging the battery module in a first time period and not charging the battery module in a second time period in a pulse-charging manner, and controlling a second power flow between the supercapacitor module and battery module to charge the battery module from the supercapacitor module in the first time period.
