Abstract

A vehicle includes an electrical storage device, a notifier, a communication device, and an electronic control unit. The electronic control unit predicts the amount of charging power of the electrical storage device and the use time in a case where external charging is performed, in accordance with the state of the electrical storage device. The electronic control unit predicts cost performance of the external charging in accordance with the amount of charging power and the use time that are predicted, and information relating to a fee-charging system. The electronic control unit controls the notifier so as to execute the notification of the cost performance.

Claims

1. A vehicle configured to receive a supply of power from a charging stand provided outside of the vehicle, the charging stand being configured to perform fee-charging on the supply of power to the vehicle in accordance with a fee-charging system based on a use time of the charging stand, the vehicle comprising:

an electrical storage device configured to perform external charging using the power supplied from the charging stand;

a notifier configured to execute a notification to a user;

a communication device configured to acquire information relating to the fee-charging system of the charging stand; and

an electronic control unit configured to;

predict an amount of charging power of the electrical storage device and the use time in a case where the external charging is performed, in accordance with a state of the electrical storage device,

predict cost performance of the external charging based on a ratio of the predicted amount of charging power to the predicted use time, and the information relating to the fee-charging system, and

control the notifier so as to execute the notification of the cost performance.

2. The vehicle according to claim 1, further comprising an input device configured to receive input from the user,

wherein the notifier is configured to urge the user to select whether or not to execute the external charging through the input device.
