Claim 16:
17. A controller for an electronic vapor provision system comprising:
a control unit; and
an aerosolizable substrate material carrying portion separably connectable to the control unit,
wherein the controller is configured to:
provide power from a battery in the control unit to a first electrical circuit in the aerosolizable substrate material carrying portion including a characteristic-carrying element and to a second electrical circuit in the aerosolizable substrate material carrying portion including a vapor generating element configured to generate an inhalable vapor from an aerosolizable substrate material,
determine a characteristic of the characteristic-carrying element when power is provided to the first electrical circuit,
operate the vapor generating element when power is provided to the second electrical circuit,
operate a switching arrangement in the aerosolizable substrate material carrying portion to selectively provide power from the battery to the second electrical circuit, the switching arrangement configured to switch between connecting the first electrical circuit with a first electrical connection terminal on the aerosolizable substrate material carrying portion and connecting the second electrical circuit with the first electrical connection terminal, wherein the aerosolizable substrate carrying portion has two electrical connection terminals for connection with the control unit comprising the first electrical connection terminal for providing power to the first electrical circuit and the second electrical circuit and an electrical earth connection for the first electrical circuit and the second electrical circuit.
