A power transfer control device within a vehicle including an in-vehicle power storage device (16, 26) that transfers power to and from an external power source and a communication unit that performs communication with the external power source to transfer the power, the power transfer control device comprising: a transfer control unit configured to execute control for transferring the power and not to be able to execute control for transferring the power under a condition in which an abnormality occurs in the communication; and a reduction processing unit configured to, under the condition in which the abnormality occurs in the communication, reduce a power consumption amount of the transfer control unit to be lower than a power consumption amount of when the transfer control unit executes control for transferring the power, a determination unit configured to determine, after an abnormality occurs in the communication, whether or not to execute a process for reducing the power consumption amount with the reduction processing unit upon receiving a travelable distance based on the present state of charge of the in-vehicle power storage device (16, 26), an obtaining unit configured to obtain information related to a minimum travel distance that is desired by a user, wherein when the communication corresponds to communication performed when the in-vehicle power storage device (16, 26) is charged from the external power source, the determination unit is configured to determine whether or not to execute the process for reducing the power consumption amount, characterized in that after the abnormality occurs in the communication, under a condition in which the travelable distance is less than or equal to the minimum travel distance, the determination unit is configured to determine to execute the process for reducing the power consumption amount with the reduction processing unit, and under a condition in which the travelable distance is greater than the minimum travel distance, the determination unit is configured to determine to retry a communication process for charging the in-vehicle power storage device (16, 26) from the external power source without executing the process for reducing a power consumption amount with the reduction processing unit. a transfer control unit configured to execute control for transferring the power and not to be able to execute control for transferring the power under a condition in which an abnormality occurs in the communication; and a reduction processing unit configured to, under the condition in which the abnormality occurs in the communication, reduce a power consumption amount of the transfer control unit to be lower than a power consumption amount of when the transfer control unit executes control for transferring the power, a determination unit configured to determine, after an abnormality occurs in the communication, whether or not to execute a process for reducing the power consumption amount with the reduction processing unit upon receiving a travelable distance based on the present state of charge of the in-vehicle power storage device (16, 26), an obtaining unit configured to obtain information related to a minimum travel distance that is desired by a user, wherein when the communication corresponds to communication performed when the in-vehicle power storage device (16, 26) is charged from the external power source, the determination unit is configured to determine whether or not to execute the process for reducing the power consumption amount, characterized in that after the abnormality occurs in the communication, under a condition in which the travelable distance is less than or equal to the minimum travel distance, the determination unit is configured to determine to execute the process for reducing the power consumption amount with the reduction processing unit, and under a condition in which the travelable distance is greater than the minimum travel distance, the determination unit is configured to determine to retry a communication process for charging the in-vehicle power storage device (16, 26) from the external power source without executing the process for reducing a power consumption amount with the reduction processing unit.
