A patent application (Publication Number: US20240039064A1) describes a rechargeable e-cigarette with innovative features. The e-cigarette includes a battery that provides a maximum voltage output when fully charged, a connector for external recharging without disassembly, and a mechanism to prevent overcharging by determining the battery's voltage output. The mechanism stops recharging if the voltage output exceeds a predefined threshold level, which is set below the maximum voltage output. Additionally, the patent details a method for operating the e-cigarette, emphasizing the importance of monitoring and preventing overcharging to ensure safe and efficient use.
Furthermore, the patent application introduces a rechargeable pack designed to contain and recharge the e-cigarette. The pack features a pack battery, connectors for external power sources, and mechanisms to prevent overcharging by monitoring the voltage output of the e-cigarette battery. The pack includes a tube for housing the e-cigarette, with a second connector for recharging the e-cigarette battery using the pack battery. The method of operating the rechargeable pack involves detecting foreign objects in the tube and protecting against current flow through the second connector if such objects are detected. These innovative features aim to enhance the safety and functionality of rechargeable e-cigarettes and their accompanying rechargeable packs.
