(EN) Various embodiments of the invention provide an electronic vapour provision system having a longitudinal axis. The electronic vapour provision system comprises a control unit and at least one cartridge configured to engage with and disengage from the control unit substantially along said longitudinal axis. The at least one cartridge includes a reservoir of liquid to be vaporised. The electronic vapour provision system further comprises an induction heating assembly comprising at least one drive coil and a plurality of heater elements. The heaters elements are located in the at least one cartridge for vaporising said liquid. The at least one cartridge is configured to feed liquid from the reservoir onto the heater elements for vaporisation. The at least one cartridge is located, when engaged with the control unit, such that the heater elements are within the at least one drive coil. The electronic vapour provision system is configured to support selective energisation of different heater elements from the plurality of heater elements.
