<P>PROBLEM TO BE SOLVED: To successively obtain information on the number of chargers capable of being used within a contract demand for charging electric vehicles. <P>SOLUTION: A charge control device 20 successively measures a power consumption of a facility 1 including one or a plurality of charging units 30 for charging an on-vehicle power storage 62 of an electric vehicle 60. The charge control device 20 figures out, on a basis of the sum of power consumption which is measured from the start time point to a prescribed time point in a determination object period for determining the contract demand of the facility 1, a virtual contract demand indicating an available electric power within the contract demand from the prescribed time point to the end time point in the determination object period. The charge control device 20, accepting the virtual contract demand or an installed electric power of the facility 1 whichever is the smaller as a maximum available electric power, determines the number of the charging units 30 allowed to be used at the maximum available electric power among the charging units 30 included in the facility 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
