Abstract

For informing a user of a current battery SOC (State Of Charge) value (%) and a cost required for a full charging, an apparatus for providing charging information of an electric vehicle includes storage that stores chargeable capacity information of a battery mounted in the electric vehicle, a communication module that receives a charging fee schedule of a charging station, a controller area network (CAN) connection module that acquires charged amount information corresponding to a current SOC value of the battery, a controller that calculates an expected charging cost based on the chargeable capacity information of the battery, the charged amount information corresponding to the current SOC value of the battery, and the charging fee schedule, and a displaying assembly that displays the calculated expected charging cost and the current SOC value of the battery.

Claims11

Dependent claims

An apparatus for providing charging information of an electric vehicle, the apparatus comprising:

storage configured to store chargeable capacity information of a battery mounted in the electric vehicle;
a communication module configured to communicate with a charging station;
a controller area network (CAN) connection module connected to a CAN;
a controller configured to:
receive a charging fee schedule of the charging station via the communication module,
acquire charged amount information corresponding to a current state of charge (SOC) value of the battery via a controller area network (CAN) connection module, and
calculate an expected charging cost based on the chargeable capacity information of the battery, the charged amount information corresponding to the current SOC value of the battery, and the charging fee schedule;
and
a display system configured to display the calculated expected charging cost and the current SOC value of the battery,
wherein the display system includes a head up display (HUD), a cluster, a first beam projector positioned around a door, and a second beam projector positioned around a charging inlet,
wherein, when the door is not opened, the controller is configured to cause the display system to display the expected charging cost and the current SOC value of the battery on the HUD,
wherein, when the door is opened, the controller is configured to cause the display system to display the expected charging cost and the current SQC value of the battery through the first beam projector on a ground, and
wherein, when the open door is closed, the controller is configured to cause the second beam projector to display the expected charging cost and the current SQC value of the battery on the ground.

A method of providing charging information of an electric vehicle, the method comprising:

storing, by storage, chargeable capacity information of a battery mounted in the electric vehicle;
receiving, by a communication module, a charging fee schedule of a charging station;
acquiring, by a controller area network (CAN) connection module, charged amount information corresponding to a current state of charge (SOC) value of the battery;
calculating, by a controller, an expected charging cost based on the chargeable capacity information of the battery and the charged amount information corresponding to the current SOC value of the battery and the charging fee schedule;
and
displaying, by a display system, the calculated expected charging cost and the current SOC value of the battery,
wherein the displaying of the expected charging cost and the current SOC value of the battery includes displaying the expected charging cost and the current SOC value of the battery through a head up display (HUD) when a door is not opened,
wherein the displaying of the expected charging cost and the current SOC value of the battery includes displaying the expected charging cost and the current SOC value of the battery through a first beam projector positioned around the door, when the door is opened, and
wherein the displaying of the expected charging cost and the current SOC value of the battery includes displaying the expected charging cost and the current SOC value of the battery through a second beam projector positioned around a charging inlet when the open door is closed.
