Abstract
The vehicle chargeable by being connected to an external charging device includes a navigation system in which a destination of the vehicle is set, a battery storing electric power supplied from the external charging device, a cooling device cooling the battery, and an Electronic Control Unit (ECU) controlling the cooling device. When the external charging device is set to the destination in the navigation system, the ECU acquires the maximum current of the external charging device from the navigation system, calculates a predicted value regarding what the SOC of the battery will be when the vehicle reaches the destination based on the navigation information from the navigation system, and operates the cooling device before the vehicle reaches the destination when the maximum current exceeds the current threshold and the predicted value is also equal to or smaller than the first SOC threshold.

Description
Vehicle with a vehicle body having a vehicle body support Technical Field The present disclosure relates to a vehicle. Background Japanese unexamined patent application publication (JP 2010-166676, 166676A) discloses a pure electric vehicle that cools a battery (electric power storage device) when the vehicle approaches a destination, thereby suppressing the temperature of the battery from becoming high when the battery is charged at the destination. Disclosure of Invention In general, when a vehicle is connected to an external charging device to charge an electric power storage device mounted in the vehicle, a charging current is limited when a temperature of the electric power storage device becomes high to suppress degradation of the electric power storage device. When the charging current is limited, the charging time will become prolonged. Therefore, cooling the electric power storage device when the vehicle approaches the destination can enable the charging time to be shortened. However, when the temperature of the power storage device is not expected to heat up while the power storage device is being charged, cooling the power storage device may cause the temperature of the power storage device to become lower than a temperature suitable for charging, which may actually lengthen the charging time. An object of the present disclosure is to shorten a charging time of an electric power storage device.

The vehicle includes a navigation system in which a destination of the vehicle is set, an electric power storage device that stores electric power supplied from an external charging device, a cooling device that cools the electric power storage device, and a control device that controls the cooling device. When the external charging device is set as a destination in the navigation system, the control device acquires a maximum current of the external charging device from the navigation system, calculates a predicted value of what a State of Charge (SOC) of the power storage device will be when the vehicle reaches the destination based on navigation information from the navigation system, and operates the cooling device before the vehicle reaches the destination when the maximum current exceeds a current threshold and the predicted value is also equal to or smaller than a first SOC threshold.

(3) The vehicle according to (2), further comprising a temperature sensor that detects a temperature of the electric power storage device. In the case where the external charging device is set as the destination in the navigation system, when the maximum current exceeds the current threshold and the predicted value is also equal to or smaller than the first SOC threshold, the control device sets the first cooling start temperature such that the higher the maximum current and the lower the predicted value, the lower the first cooling start temperature is set, and operates the cooling device in accordance with the temperature of the electric power storage device reaching the first cooling start temperature.
