Abstract: An aerosol provision system can include an aerosol provision device including a heater assembly configured to heat aerosol generating material, and a device battery configured to supply power to cause the heater assembly to heat the aerosol generating material; and a base unit configured to removably hold the aerosol provision device, the base unit including a base battery, and the base unit being configured to connect to a power supply to supply electrical charge to the base battery. The system also can include an indicator assembly and a controller.

Abstract: A module for use with an aerosol provision device is described, the module including a housing and one or more connectors configured to interact with an aerosol provision device or another module. In use, the module is configured to be operatively connected by means of the one or more connectors to the aerosol provision device, either directly or via one or more further modules. The module can include one or more components configured to provide the operatively connected aerosol provision device with additional functionality, in use. There is also provided an aerosol provision device and a system.

Abstract: A non-combustible aerosol provision system is described. The non-combustible aerosol provision system includes a non-combustible aerosol provision device and a charging apparatus for use with the non-combustible aerosol provision device. The non-combustible aerosol provision device includes a first rechargeable battery. The charging apparatus includes a housing, a second rechargeable battery disposed within the housing, a first electrical connection port for connecting to the non-combustible aerosol provision device, a second electrical connection port for connecting to an external power source and control circuitry.

Abstract: A case for an aerosol delivery device, and a method for using the case, is described and can include a lid having an open position and a closed position; a magnet and hall sensor pair configured to provide a signal indicative of whether the lid is in the open position or the closed position; and a controller configured to receive a signal from the hall sensor indicative of whether the lid is open or closed.

Abstract: An apparatus, method and computer program can include generating, obtaining or receiving a first control signal, at or from a control module, for switching elements of a first switching arrangement, wherein the control module implements a heating phase operation and a non-heating phase of operation of a first resonant circuit. The first resonant circuit includes one or more inductive elements and one or more capacitive elements, wherein the one or more inductive elements are for inductively heating a first susceptor arrangement to heat an aerosol generating material to thereby generate an aerosol. The first switching arrangement has a first state (in which a varying current is generated from a voltage supply and flows through the one or more inductive elements of the first resonant circuit) and a second state (in which the first switching arrangement is non-conducting).

Abstract: A charging apparatus is provided. The charging apparatus includes a first power source; a first device for supplying electrical power to a non-combustible aerosol provision device; and a second device for receiving electrical power from an external power source. In a first mode of operation, the charging apparatus is arranged to supply electrical power to one or more aerosol generators of a non-combustible aerosol provision device.

Abstract: An apparatus and a method is described comprising: charging a battery of an aerosol generating device in a first mode of operation when a charge level of the battery is below a first threshold; and charging the battery of the aerosol generating device in a second mode of operation when the charge level of the battery is above the first threshold.

Abstract: An apparatus for a non-combustible aerosol provision system is described comprising: a charging unit configured to charge a battery of said aerosol provision system; a circuit comprising a control module, wherein the control module outputs a first control signal having a charge enable state and a charge disable state; and a protection module configured to decouple the circuit from said battery when the battery voltage is below a first threshold level. The charging unit is configured to charge the battery unless the first control signal has the charge disable state.
