Abstract

An electric vehicle comprising a battery checks through an electric vehicle power supply device whether the battery can be charged. The electric vehicle charges the battery through the electric vehicle power supply device if the battery can be charged through the electric vehicle power supply device. The electric vehicle transmits to a user terminal device a charge information notification message, which indicates a failure to begin charging, when the battery cannot be charged through the electric vehicle power supply device.

Claims

1. An operating method of an electric vehicle including a battery, the method comprising:

checking whether the battery is chargeable through an electric vehicle power supply device;

if the battery is chargeable through the electric vehicle power supply device, charging the battery through the electric vehicle power supply device; and

if the battery is not chargeable through the electric vehicle power supply device, transmitting a first charging information notification message indicating a charging start failure to a user terminal device.

2. The method according to claim 1, wherein the checking whether the battery is chargeable through the electric vehicle power supply device comprises:

performing an authentication operation with the electric vehicle power supply device; and

checking whether the battery is chargeable through the electric vehicle power supply device on the basis of a result of the authentication operation.

3. The method according to claim 2, wherein if the authentication operation is failed, the first charging information notification message comprises charging error information indicating an authentication failure.

4. The method according to claim 3, wherein the performing of the authentication operation with the electric vehicle power supply device comprises performing an authentication operation with the electric vehicle power supply device through SAE J2836-1 and SAE J2847-1.

5. The method according to claim 1, wherein the checking whether the battery is chargeable through the electric vehicle power supply device comprises:

checking an initial state of charging of the battery;

checking whether the battery is chargeable through the electric vehicle power supply device on the basis of whether the initial charging state of the battery corresponds to a maximum charging capacity of the battery.

6. The method according to claim 5, wherein when the initial charging state of the battery corresponds to the maximum charging capacity of the battery, the first charging information notification message comprises charging error information indicating that the initial charging state of the battery corresponds to the maximum charging capacity of the battery.

7. The method according to claim 1, wherein the checking whether the battery is chargeable through the electric vehicle power supply device comprises:

checking whether the electric vehicle power supply device is capable of providing power to the electric vehicle; and

checking whether the battery is chargeable through the electric vehicle power supply device on the basis of whether the electric vehicle power supply device is capable of providing the power to the electric vehicle.

8. The method according to claim 7, wherein if the electric vehicle power supply device is not capable of providing the power to the electric vehicle, the first charging information notification message comprises charging error information indicating that the electric vehicle power supply device is not capable of providing the power to the electric vehicle.

9. The method according to claim 1, wherein the checking whether the battery is chargeable through the electric vehicle power supply device comprises:

checking whether a time of use price is valid; and

checking whether the battery is chargeable through the electric vehicle power supply device on the basis of whether the time of use price is valid.

10. The method according to claim 9, wherein if the time of use price is invalid, the first charging information notification message comprises charging error information indicating that the time of use price is invalid.

11. The method according to claim 1, wherein the checking whether the battery is chargeable through the electric vehicle power supply device comprises:

performing a communication connection setting with the electric vehicle power supply device when an SAE J1772 connector is connected; and

checking whether the battery is chargeable through the electric vehicle power supply device on the basis of a result of the communication connection setting.

12. The method according to claim 11, wherein if the communication connection setting is failed, the first charging information notification message comprises charging error information indicating the communication connection setting failure.

13. The method according to claim 1, further comprising:

checking a current state of charging of the battery; and

transmitting a second charging information notification message including information the current state of charging of the battery to a user terminal device.

14. The method according to claim 13, further comprising:

detecting a charging completion of the battery; and

if the charging completion of the battery is detected, transmitting a second charging information notification message indicating the charging completion of the battery to the user terminal device.
