<P>PROBLEM TO BE SOLVED: To unfailingly charge a storage battery installed on an automobile, using the power generated by a solar battery. <P>SOLUTION: An estimated photovoltaic power generated amount and an estimated charging amount of the storage battery for an automobile are calculated, and the distribution of the power is controlled so that the photovoltaic power generation amount may be supplied to the storage battery for an automobile (100-106). If the estimated photovoltaic power amount is larger than the estimated charged amount, power distribution is controlled so that excessive power is supplied to loads in dwellings (108, 112). If the estimated photovoltaic power generation amount is larger than a power generated amount obtained by adding the estimated charged amount to the loads of the dwellings, power distribution is controlled so that the excessive power is supplied to the storage battery for a dwelling (114, 116, 122), and the storage battery is charged, when further, the excessive power becomes available (124-126). <P>COPYRIGHT: (C)2011,JPO&INPIT |
