<p><P>PROBLEM TO BE SOLVED: To improve a power supply and demand improving system that reduces a loss in opportunity of selling and buying surplus power generated by distributed type generators, which becomes a problem when a voltage in the distribution line of a building comes close to the upper limit of its tollerable voltage. <P>SOLUTION: The power supply and demand improving system has a charge stand, which includes a charger for charging the battery of an electric vehicle by commercial power supplied via a transformer, a voltage detector, which detects the voltage in the distribution line, and a voltage determination control unit, which performs control of accelerating the use of the charge stand, according to the results of having compared the voltage detected by the voltage detector with a specified voltage. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
