9. The vehicle according to claim 7 , wherein the power management apparatus is configured to:

sum values of the respective rows and columns according to a predetermined priority of respective rows and columns when a reference time has elapsed since the convenience load was operated by the user; and

reduce the amount of power consumption of the convenience load corresponding to the remaining rows and columns when the sum of the values of the rows and columns is greater than the amount of power availability.

10. The vehicle according to claim 7 , wherein the power management apparatus is configured to:

when a reference time has not elapsed since the convenience load was operated by the user, sum all the values of the columns, which correspond to the convenience load operated by the user, and then sum the values of respective rows and columns according to a predetermined priority of the respective rows and columns; and

when the sum of the values of the rows and columns is greater than the amount of power availability, reduce the amount of power consumption of the convenience load corresponding to the remaining rows and columns.

11. A method of controlling a vehicle that includes a battery and a plurality of convenience loads, the method comprising:

storing a power consumption table that includes information related to power consumption depending on operation levels of the plurality of convenience loads and a priority depending on operation levels of the plurality of convenience loads;

calculating an amount of power availability based on a state of charge of the battery;

calculating an amount of power consumption based on operation information of the plurality of convenience loads; and

lowering the operation levels of the convenience loads based on the power consumption table when the amount of power consumption is greater than the amount of power availability.

12. The method according to claim 11 , wherein lowering the operation levels of the convenience loads comprises:

reducing the power consumption of the convenience loads based on the power consumption table according to a first process when the amount of power consumption is greater than the amount of power availability;

reducing the power consumption of the convenience loads based on the power consumption table according to the first process when a reference time has elapsed since the convenience load was operated by a user; and

reducing the power consumption of the convenience loads based on the power consumption table according to a second process different from the first process when the reference time has not elapsed since the convenience load was operated by the user.

13. The method according to claim 11 , wherein the power consumption table comprises a plurality of rows and a plurality of columns,

wherein the plurality of columns correspond to the plurality of convenience loads, respectively, and

wherein the plurality of rows correspond to the operation levels of the convenience loads, respectively.

14. The method according to claim 13 , wherein the plurality of rows and the plurality of columns have different priorities.

15. The method according to claim 14 , wherein the plurality of rows and the plurality of columns of the power consumption table comprise the amount of power consumption of each convenience load depending on the operation level of the plurality of convenience loads.

16. The method according to claim 15 , wherein lowering the operation levels of the convenience loads comprises:

summing values of the respective rows and columns according to a predetermined priority of the respective rows and columns when the amount of power consumption is greater than the amount of power availability; and

reducing the amount of power consumption of the convenience load corresponding to the remaining rows and columns when the sum of the values of the rows and columns is greater than the amount of power availability.
