Application: Aerosol generation device power system (Patent ID: US20230397671A1)
The patent filed by Japan Tobacco Inc. describes an aerosol generation device that includes a power system with a supercapacitor module and a battery module, connectable to an external power source. The device is controlled by a controller to implement a pulse-charging regime, where the first power flow from the external power source is cyclically switched between charging the battery module and not charging it in a pulse-charging manner. Additionally, the controller controls a second power flow between the supercapacitor module and battery module to charge the battery module from the supercapacitor module during specific time periods.
The claims associated with the patent detail various aspects of the aerosol generation device, including the configuration of the power system, the control of power flows, and the components involved such as supercapacitors, batteries, and voltage converters. The method described in the patent involves controlling the pulse-charging regime of the power system by managing the power flows between the different modules. Furthermore, the patent includes a computer-readable medium storing instructions for controlling the power system of the aerosol generation device. Overall, the patent focuses on optimizing the charging process of the device to enhance its efficiency and performance.
