Vehicle that determines whether component related to supply of thermal energy from heater to power storage device is malfunctioning

A vehicle, comprising:

• a motor that is driven by electric power supplied from a power storage device and that also functions as a driving source when the vehicle is traveling;
• a heater that is configured to supply thermal energy to an air conditioner that supplies warm air into a vehicle cabin, and to the power storage device, via a thermal transfer medium;
• a first circuit portion that is configured to deliver the thermal energy to the air conditioner by causing the thermal transfer medium that is warmed by the heater to flow to a side of the air conditioner;
• a second circuit portion that is configured to deliver the thermal energy to the power storage device by causing the thermal transfer medium that is warmed by the heater to flow to a side of the power storage device;
• a flow rate adjustment unit that is configured to cause the thermal transfer medium flowing out of the heater to flow to the first circuit portion and the second circuit portion, and that is configured to adjust a first flow rate of the thermal transfer medium flowing through the first circuit portion, and a second flow rate of the thermal transfer medium flowing through the second circuit portion;
• a first thermometer that is configured to measure a first temperature of the thermal transfer medium immediately before supplying the thermal energy to the power storage device on the second circuit portion;
• and
• a control unit that controls the flow rate adjustment unit such that the second flow rate is restricted to a first predetermined flow rate that is smaller than the first flow rate when the air conditioner is started in a state of a predetermined air temperature or lower, determines the second circuit portion to be normal when the first temperature reaches a first predetermined temperature or higher within a predetermined amount of time from starting the air conditioner and also controls the flow rate adjustment unit to stop inflow of the thermal transfer medium to a side of the second circuit portion, and determines the second circuit portion to be abnormal when the first temperature does not reach the first predetermined temperature within the predetermined amount of time from the starting and also controls the flow rate adjustment unit to stop the inflow of the thermal transfer medium to the side of the second circuit portion.
