Aerosol Heater Battery Identification for Adaptive Power Modes

A protection circuit module is introduced as an intermediary component between the battery and the controller. This module includes a first identification electrode that contacts the battery to acquire identification information, and a protection circuit that processes this information to determine battery type and temperature. By placing the identification function in this intermediary module rather than directly in the controller, the system achieves accurate battery type identification while maintaining a clear separation of concerns and manageable complexity.

The system dynamically adjusts the operation mode based on the identified battery type. The controller receives battery type information from the protection circuit module and automatically selects appropriate operating parameters such as power output limits, heating temperature, and puff detection thresholds. This dynamic adaptation allows the device to optimize performance for different battery types (e.g., high-capacity vs. low-capacity batteries) without requiring manual configuration, while the automated nature of the process prevents complexity from escalating.

The protection circuit module is designed to perform multiple functions simultaneously: it identifies battery type through electrical characteristic analysis, measures battery temperature through the same identification electrode, and provides overcharge/over-discharge protection. By consolidating these functions into a single module rather than using separate sensors and circuits for each function, the system achieves accurate temperature measurement while minimizing the increase in device complexity through functional integration.
