Vehicle, charging method, and computer apparatus

A vehicle comprising:

• a charging port to which electric power from outside of the vehicle is inputted;
• a power storage;
• a charger;
• and
• a control device that controls the charger, wherein
• the charger includes a first charger and a second charger,
• the first charger is configured to charge the power storage with the electric power from the charging port while a first charging path is connected, the first charging path leading from the charging port via the first charger to the power storage,
• the second charger is configured to charge the power storage with the electric power from the charging port while a second charging path is connected, the second charging path leading from the charging port via the second charger to the power storage,
• the second charging path is provided with a switching device that switches between connection and disconnection of the second charging path, and
• the control device controls the switching device to
• disconnect the second charging path before charging of the power storage,
• maintain the first and second charging paths in a state where the second charging path is disconnected and the first charging path is connected during precharging of the first charger, and
• connect the second charging path after the precharging of the first charger is completed, the vehicle further comprising a power feed port for output of the electric power to the outside of the vehicle, wherein
• the first charger is configured to feed the electric power to the power feed port with the electric power from the power storage while a first power feed path is connected, the first power feed path leading from the power storage via the first charger to the power feed port,
• the first charging path is provided with a first contact relay that connects any one of the first charging path and the first power feed path and disconnects the other of the first charging path and the first power feed path,
• the second charger is configured to feed the electric power to the power feed port with the electric power from the power storage while a second power feed path is connected, the second power feed path leading from the power storage via the second charger to the power feed port, and
• the switching device includes a second contact relay that connects any one of the second charging path and the second power feed path and disconnects the other of the second charging path and the second power feed path.

A charging method of charging a power storage mounted on a vehicle with electric power inputted to a charging port of the vehicle, the vehicle comprising a power feed port for output of the electric power to outside of the vehicle, the charging method comprising:

• connecting a first charging path leading from the charging port via a first charger to the power storage;
• disconnecting a second charging path leading from the charging port via a second charger to the power storage;
• performing precharging of the first charger while the second charging path is disconnected and the first charging path is connected;
• determining whether the precharging of the first charger has been completed;
• connecting both of the first charging path and the second charging path when it is determined that the precharging of the first charger has been completed;
• and
• feeding, via the second charger, the electric power to the power feed port with the electric power from the power storage while a power feed path is connected, the power feed path leading from the power storage via the second charger to the power feed port, wherein a switching device includes a contact relay that connects any one of the second charging path and the power feed path and disconnects the other of the second charging path and the power feed path.
