<P>PROBLEM TO BE SOLVED: To provide a charging/discharging system that does not require a user to reset a discharge setting value of an electric vehicle. <P>SOLUTION: The charging/discharging system includes: an electric vehicle 10; and a charging/discharging device 20 connected to a commercial power grid 43. A second controller 23 of the charging/discharging device 20 holds a discharge regulation value DR of the commercial power grid 43, and transmits the discharge regulation value DR to a first controller 12 of the electric vehicle 10 during discharge of a battery 11. A system power monitoring device 14 of the electric vehicle 10 acquires and transmits a power state signal VW indicating a state of power of the commercial power grid 43 to the first controller 12. On the basis of the discharge regulation value DR and the power state signal VW, the first controller 12 determines a discharge setting value DS that prescribes a form of power outputted by a power conversion device 13 during the discharge of the battery 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
