<P>PROBLEM TO BE SOLVED: To properly and efficiently enable a charging to a plurality of electric vehicles under an environment where electric power to be supplied is limited. <P>SOLUTION: A charging system starts supplying power to a charging stand 4 when a current value Ir+Δi is less than a maximum allowable current Imax, where the Ir+Δi is obtained by adding a current value Ir which is a current value supplied to the charging stand 4 where a charging is reserved, and a maximum charging current Δi which is a maximum charging current to be supplied to the charging stand 4 at a charging regarding the charging reservation. The charging system controls the charging reservation as a stand-by state when the current value Ir+Δi is more than the maximum allowable current Imax. The charging system stops supplying power to the other charging stands 4 when their charging duration time exceeds a maximum charging duration time Tmax, and starts supplying power to the charging stands 4 in regard to the other charging reservations when the current value Ir+Δi obtained for the controlled charging reservation is equal to or less than the maximum allowable current Imax which is a maximum current value that a power source 3 can supply. <P>COPYRIGHT: (C)2012,JPO&INPIT |
