Charging and discharging system for a vehicle including a first fuse in the vehicle and a second fuse in a cable connected to the vehicle

A vehicle comprising:

• an electric storage device configured to store DC power;
• a first fuse having one terminal and the other terminal, the one terminal of the first fuse being connected to the electric storage device;
• a relay having one terminal and the other terminal, the one terminal of the relay being connected to the other terminal of the first fuse;
• an inlet connected to the other terminal of the relay, the inlet being connected to a charging and discharging device via a cable in a charging mode and a discharging mode, the charging mode being a mode in which the electric storage device is charged, the discharging mode being a mode in which the electric storage device is discharged;
• and
• an controller configured to control the relay,
• wherein the controller is configured to determine whether the first fuse is melted and cut more easily than a second fuse on the basis of specification of the first fuse stored in advance and specification of the second fuse, the second fuse is included in the cable, and the specification of the second fuse is transmitted from the charging and discharging device before the discharging of the electric storage device is started in the discharging mode, and
• the controller is configured to turn on the relay and to transmit a signal for permitting the discharging of the electric storage device to the charging and discharging device when the first fuse is determined to be melted and cut more easily than the second fuse, and
• the controller is configured to turn off the relay and to transmit a signal for inhibiting the discharging of the electric storage device to the charging and discharging device when the first fuse is determined to be not melted and cut more easily than the second fuse.
