Claim 15:
16. A control unit for an electronic vapor provision system which is separably connectable to an aerosolizable substrate material carrying portion comprising a first electrical circuit including a characteristic-carrying element and a second electrical circuit including a vapor generating element configured to generate an inhalable vapor from an aerosolizable substrate material, the second electrical circuit selectively providable with power from the battery when power is supplied to the aerosolizable substrate material carrying portion, the control unit configured to provide power from a battery in the control unit to components of the electronic vapor provision system, and comprising:
a controller configured to:
control components of the electronic vapor provision system and to operate in a first mode in which power is provided from the battery to the first electrical circuit to determine a characteristic of the characteristic-carrying element, and to operate in a second mode in which power is provided from the battery to the second electrical circuit to operate the vapor generating element, and
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.
