A vehicle includes a battery as a power storage device that can be charged and discharged, a booster unit, an inverter, and a motor generator operating as a vehicle driving unit receiving electric power supply from the battery to drive the vehicle, a coupling unit coupling the vehicle with an external power supply for charging the battery from the outside of the vehicle, and a control device performing control related to the battery. The control device determines whether or not a destination is a charging-available place where the battery can be charged from the outside of the vehicle, and if the destination is a charging-available place, performs control related to the battery so that the temperature of the battery is a charging-efficient temperature on arrival at the destination.

1. A vehicle comprising: a power storage device that can be charged and discharged;a vehicle driving unit receiving electric power supply from said power storage device to drive the vehicle;a coupling unit coupling the vehicle with an external power supply to charge said power storage device from the outside of the vehicle; anda control device performing control related to said power storage device, whereinsaid control device determines whether or not a destination is a charging-available place where said power storage device can be charged from the outside of the vehicle and, if said destination is a charging-available place, performs control related to said power storage device so that a temperature of said power storage device becomes a charging-efficient temperature when the vehicle arrives at said destination. 2. The vehicle according to claim 1, wherein said control device performs control related to said power storage device so that a temperature of said power storage device does not exceed a prescribed upper limit temperature during travel, if said destination is not a charging-available place. 3. The vehicle according to claim 1, wherein said control device includes input means for inputting said destination,determination means for determining whether or not said destination is a charging-available place,detection means for detecting a present temperature of said power storage device,obtaining means for obtaining reference information that affects a temperature of said power storage device when said vehicle arrives at the input destination,prediction means for predicting a temperature of said power storage device on arrival at said destination, based on the present temperature of said power storage device and said reference information,temperature control means for controlling a temperature of said power storage device, andtemperature management means for managing a temperature of said power storage device during travel, if said destination is a charging-available place, by setting an intermediate target temperature of the temperature of said power storage device during travel of said vehicle so that the predicted temperature of said power storage device on arrival at said destination is a charging-efficient temperature, based on the detected temperature of said power storage device, and by controlling said temperature control means so that the temperature of said power storage device reaches said intermediate target temperature. 4. The vehicle according to claim 3, further comprising a power source capable of driving said vehicle, which is different from said power storage device, wherein said temperature control means controls a temperature of said power storage device by controlling a frequency of use of said power source and charging/discharging of said power storage device. 5. The vehicle according to claim 3, wherein said temperature control means includes cooling means for cooling said power storage device. 6. The vehicle according to claim 3, wherein said temperature control means includes heating means for heating said power storage device. 7. The vehicle according to claim 3, further comprising means for determining whether or not a present vehicle location is in the vicinity of the input destination, wherein said temperature management means starts defining said intermediate target temperature so that the predicted temperature of the power storage device on arrival at said destination is a charging-efficient temperature, if said destination is a charging-available place and if it is determined that the present vehicle location is in the vicinity of said destination. 8. The vehicle according to claim 7, wherein said temperature management means controls said temperature control means so that a temperature of said power storage device does not exceed a prescribed upper limit temperature, if it is determined that said present vehicle location is not in the vicinity of said destination, and said temperature management means controls said temperature control means so that a temperature of said power storage device on arrival at the destination becomes a charging-efficient temperature, if it is determined that said present vehicle location is in the vicinity of said destination. 9. A temperature control method of a power storage device in a vehicle including a power storage device that can be charged and discharged, a vehicle driving unit receiving electric power supply from said power storage device to drive the vehicle, and a coupling unit coupling the vehicle with an external power supply to charge said power storage device from the outside of the vehicle, the method being performed by a control device in the vehicle, and comprising the steps of: determining whether or not a destination is a charging-available place where said power storage device can be charged from the outside of the vehicle; andperforming control related to said power storage device so that a temperature of said power storage device becomes a charging-efficient temperature when the vehicle arrives at said destination, if said destination is a charging-available place. 10. The temperature control method of a power storage device according to claim 9, wherein said step of performing control performs control related to said power storage device so that a temperature of said power storage device does not exceed a prescribed upper limit temperature during travel, if said destination is not a charging-available place. 11. The temperature control method of a power storage device according to claim 9, further comprising the steps of: inputting said destination;detecting a present temperature of said power storage device;obtaining reference information that affects a temperature of said power storage device when said vehicle arrives at the input destination; andpredicting a temperature of said power storage device on arrival at said destination, based on the present temperature of said power storage device and said reference information, whereinsaid step of performing control, if said destination is a charging-available place, manages a temperature of said power storage device during travel by setting an intermediate target temperature of the temperature of said power storage device during travel of said vehicle so that the predicted temperature of said power storage device on arrival at said destination is a charging-efficient temperature, based on the detected temperature of said power storage device, and by controlling a temperature control means so that the temperature of said power storage device becomes said intermediate target temperature.
