Abstract: An apparatus for displaying a distance to empty of a vehicle includes a controller configured to: estimate a mass of the vehicle, which increases or decreases while the vehicle is running; to calculate a driving energy consumption using a past-learned energy consumption based on a mass level corresponding to the increase or decrease in mass of the vehicle while the vehicle is running, and a current energy consumption of the vehicle; to calculate the distance to empty of the vehicle based on the driving energy consumption; to determine whether to update the distance to empty displayed on a display based on the mass level while the vehicle is running; and to update display information on the display based on the distance to empty.

Abstract: An apparatus, a system, and a method are for automatically billing a vehicle left unattended in a charging station. The automatic billing apparatus includes a processor that provides a vehicle charging service at a charging station, determines that a vehicle is unattended after charging is completed, and performs a billing based on an unattended time. The apparatus further includes a storage that stores data obtained by the processor when the billing is performed.

Abstract: A method of calculating power consumption of an air conditioner is provided. The method includes calculating, b a controller, a parameter of an autoregressive moving-average (ARMA) model using past initial temperature and target temperature data of an air conditioner as an input variable of the ARMA model, and past accumulated power consumption data of the air conditioner as an output variable of the ARMA model. The controller is configured to set a current target temperature of the air conditioner and detect an indoor temperature of a vehicle, in which the air conditioner is installed. In addition, the controller is configured to substitute the current target temperature, the indoor temperature, and the parameter to the ARMA model, and predict current accumulated power consumption of the air conditioner.
