Abstract
An electronic vapor provision system includes a control unit including: a battery for providing electrical power to a heater which is used to produce vapor, and a controller. The controller is configured to collect information, during user operation of the electronic vapor provision system, relating to: power consumption from the battery due to operation of the heater to produce vapor, and re-charging of the battery. The controller is further configured to maintain a model of power consumption from the battery by the electronic vapor provision system and of the timings of re-charging the battery, wherein the model is formed or updated from the collected information. The model is further configured to predict from the model whether an estimated power consumption from the battery by the electronic vapor provision system will discharge down to a threshold level of charge before an estimated next re-charging time, and if so, perform a user notification and/or mitigation action in response to the prediction.
