Solution Overview
Problem
Aerosol generation devices face challenges in providing fast heating and efficient energy use, particularly in maintaining a consistent aerosol generation temperature and prolonging battery lifespan.
Innovation Solution
The integration of a power system comprising a supercapacitor and a battery, controlled by a controller to operate in multiple modes, including float, preheating, and charging modes, allows for efficient energy management, where the supercapacitor is charged during float mode and used for fast preheating, reducing battery stress and extending its lifespan.

1Duration of action of stationary object
If a battery is used to power the heater for preheating and maintaining temperature, then the device can operate continuously, but the battery lifespan is reduced and charging time between uses is required
Solution Approach 1:
The power system is segmented into two distinct energy storage components: a battery for sustained energy supply and a supercapacitor for rapid energy delivery during preheating. This segmentation allows each component to operate in its optimal performance range, with the supercapacitor handling high-power transient demands and the battery providing baseline power, thereby extending battery lifespan and eliminating charging wait times between uses.
Solution Approach 2:
The supercapacitor is pre-charged during float mode (when the heater is maintaining temperature) so that it is ready to deliver immediate high-power output when preheating is required. This preliminary charging action during normal operation eliminates the need for external charging between uses and reduces the battery's stress by preparing the supercapacitor in advance.
2Speed
If the heater is heated quickly to aerosol generation temperature, then user experience is improved, but energy consumption increases and battery stress increases
Solution Approach 1:
The power delivery system dynamically switches between the supercapacitor and battery based on the operational phase. During preheating, the supercapacitor provides high-power dynamic output for rapid heating. During float mode, the system transitions to lower-power operation where the battery sustains the heater at target temperature while charging the supercapacitor. This dynamic power management achieves fast heating without excessive overall energy consumption.
3Power
If the battery is used for preheating, then sufficient power is available, but the battery is stressed and lifespan is reduced
Solution Approach 1:
The supercapacitor acts as an intermediary component between the battery and the heater during preheating operations. It receives charge from the battery during float mode and then delivers the high-power pulses needed for rapid preheating, shielding the battery from direct high-stress conditions. This intermediary role preserves battery reliability while maintaining sufficient power availability for preheating.
