<P>PROBLEM TO BE SOLVED: To allow a user to know a future charging state intuitively. <P>SOLUTION: An in-vehicle battery is charged by connecting a charging plug 7 extended from a charging device 3 in a charging station CH to a vehicle V (in-vehicle battery of the vehicle V). For example, variation with time expected in a period ranging from the present to the future is displayed in a line graph on a display screen 4 provided in the charging station CH for the in-vehicle battery's charging amount and electricity rate, respectively. Time for charging in a usual mode and time for charging in a subsequent economy mode can be changed by operating a slider 12, and the form of the line graph is changed according to position change of the slider 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
