Document Type and Number:
Japanese Patent JP2019110643
Kind Code:
A
Abstract:
To provide a charge/discharge device configured to easily acquire a battery residual amount without performing charge/discharge start processing for acquiring the battery residual amount.SOLUTION: A power system 10 is connected between a vehicle 60 on which a storage battery 61 is mounted, and a house 50. A charge/discharge device 20 comprises: a charge/discharge connector Co which is connected to the vehicle to charge/discharge the storage battery; a power conversion part 23 which performs power conversion in a state where the power conversion part is connected with the vehicle by the charge/discharge connector; a control part 24 which controls the power conversion part and charges/discharges the storage battery; a detection part 26 which detects whether the charge/discharge connector is connected to the vehicle; and a storage part 25 which stores a battery residual amount in a case where the charge/discharge of the storage battery is finished. The control part has an automatic operation mode and, in a case where the connection to the vehicle is continuously detected after the end of the charge/discharge of the storage battery, starts automatic operation in the automatic operation mode due to the battery residual amount stored in the storage part and, in a case where the connection to the vehicle is not detected after the end of the charge/discharge of the storage battery, updates the battery residual amount stored in the storage part into an invalid state.SELECTED DRAWING: Figure 1
