Abstract

An aerosol-generating system includes an electric heater, a battery and control circuitry. The electric heater is configured to vaporize an aerosol-forming substance. The battery is configured to power the electric heater. The control circuitry is configured to: prevent charging of the battery in response to detecting that the electric heater is in an operation state; or prevent operation of the electric heater in response to detecting that the battery is in a charging state.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for controlling an aerosol-generating system including an electric heater configured to vaporize an aerosol-forming substance, a battery configured to power the electric heater, a temperature sensor, and control circuitry connected to the temperature sensor, the method comprising:
 detecting, by the temperature sensor, initiation of operation of the electric heater; and   preventing charging of the battery based on the detecting that the electric heater is in operation.   
     
     
         2 . The method according to  claim 1 , further comprising:
 detecting whether a replaceable cartridge is connected to a battery portion of the aerosol-generating system; and   preventing charging of the battery in response to detecting that the replaceable cartridge is connected to the battery portion.   
     
     
         3 . The method according to  claim 1 , further comprising:
 detecting activation of the electric heater; and   preventing the charging of the battery in response to detecting the activation of the electric heater.   
     
     
         4 . The method according to  claim 1 , further comprising:
 detecting activation of the electric heater;   detecting that the battery is in a charging state; and   preventing operation of the electric heater after detecting the activation of the electric heater, in response to detecting that the battery is in the charging state.   
     
     
         5 . The method according to  claim 1 , further comprising:
 detecting a charging state of the battery by detecting whether a USB cable is connected to a USB port of the aerosol-generating system.   
     
     
         6 . The method according to  claim 1 , further comprising:
 detecting, by a charging sensor, whether the battery is in a charging state.   
     
     
         7 . The method of  claim 6 , further comprising:
 preventing operation of the electric heater based on the detecting that the battery is in the charging state.   
     
     
         8 . The method of  claim 6 , further comprising:
 preventing operation of the electric heater after the initiation of operation of the electric heater, based on the detecting that the battery is in the charging state.   
     
     
         9 . The method according to  claim 1 , further comprising:
 detecting, by a current sensor, the initiation of operation of the electric heater.   
     
     
         10 . A method for controlling an aerosol-generating system including an electric heater configured to vaporize an aerosol-forming substance, a battery configured to power the electric heater, a temperature sensor, and control circuitry connected to the temperature sensor, the method comprising:
 detecting, by the temperature sensor, initiation of operation of the electric heater;   detecting that the battery is in a charging state;   preventing operation of the electric heater based on detecting that the battery is in the charging state; and   preventing charging of the battery based on the detecting that the electric heater is in operation.   
     
     
         11 . The method according to claim  20 , wherein the detecting that the battery is in the charging state includes detecting whether a USB cable is connected to a USB port of the aerosol-generating system. 
     
     
         12 . The method according to  claim 11 , wherein the preventing charging of the battery includes preventing charging of the battery based on the initiation of operation of the electric heater. 
     
     
         13 . The method according to  claim 10 , wherein the preventing charging of the battery includes preventing charging of the battery based on the initiation of operation of the electric heater. 
     
     
         14 . The method according to  claim 10 , further comprising:
 preventing operation of the electric heater after the initiation of operation of the electric heater based on the detecting that the battery is in the charging state.   
     
     
         15 . The method according to  claim 10 , wherein the detecting that the battery is in the charging state includes detecting, by a charging sensor, the charging state of the battery. 
     
     
         16 . The method according to  claim 15 , wherein the preventing charging of the battery includes preventing charging of the battery based on the initiation of operation of the electric heater. 
     
     
         17 . The method according to  claim 10 , further comprising:
 detecting whether a replaceable cartridge is connected to a battery portion of the aerosol-generating system; and   preventing charging of the battery in response to detecting that the replaceable cartridge is connected to the battery portion.
