<p><P>PROBLEM TO BE SOLVED: To solve the following problem associated with a charger-discharger installed especially for domestic use: the capacity of the charger is insufficient to quickly charge a hybrid vehicle or the like in a short time. <P>SOLUTION: The household charger-discharger includes a storage battery that is connected to a movable body, such as an automobile, equipped with a power storing means and is used to charge the power storing means of the movable body at home. The charger-discharger includes a first power converting means connected to an electric power system through a first circuit breaker. The direct current portion of the first power converting means includes a second power converting means for adjusting direct-current voltage level. The direct current portion of the first power converting means includes a third power converting means for converting direct current into alternating current. The alternating-current output of the third power converting means is connected to a second circuit breaker and the movable body. Another second circuit breaker is connected to the first circuit breaker on the first power converting means side. Another second power converting means is connected to the storage battery on the direct current side. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
