The electrified vehicle includes a communication unit compatible with a plurality of the versions of the predetermined communication standard. The electrified vehicle further includes a control unit configured to control the communication unit in such a manner that power control protocol communication between the electrified vehicle and the power station is performed using the predetermined communication standard. Priority levels are set in advance for the plurality of the versions. The control unit is configured to decide the version to be used for the power control protocol communication based on the priority levels. ## Claims ### Claim 1 An electrified vehicle that is able to perform power control including either or both of charging from a power station compatible with at least one version of a predetermined communication standard and power supply to the power station, the electrified vehicle comprising: a communication unit configured to be compatible with a plurality of the versions of the predetermined communication standard; and a control unit configured to control the communication unit in such a manner that power control protocol communication between the electrified vehicle and the power station is performed using the predetermined communication standard, wherein: the communication unit is configured to acquire information on a result of a past power control protocol communication for each of the plurality of versions, and the control unit is configured to decide the version to be used for the power control protocol communication based on the information on the result. ### Claim 2 (depends on 1) The electrified vehicle according to claim 1, wherein: the information on the result includes information on whether a past power control protocol communication was possible; the plurality of the versions includes the version with which the past power control protocol communication was possible and the version with which the past power control protocol communication was not possible; and the control unit is configured to decide the version with which the past power control protocol communication was possible as the version to be used for the power control protocol communication. ### Claim 3 (depends on 2) The electrified vehicle according to claim 2, wherein the control unit is configured to, when communication using the plurality of the versions with which the past power control protocol communication was possible all fails in the power control protocol communication, control to switch to communication using the version with which the past power control protocol communication was not possible. ### Claim 4 (depends on 3) The electrified vehicle according to claim 3, wherein the control unit is configured to, when the communication using the version with which the past power control protocol communication was not possible is successful, control the communication unit in such a manner that information on whether the power control protocol communication was possible is updated for the version with which the power control protocol communication is successful. ### Claim 5 (depends on 1) The electrified vehicle according to claim 1, wherein: the communication unit is configured to communicate with a server storing the information on the result of the power control protocol communication; and the control unit is configured to control the communication unit in such a manner that the information on the result of the power control protocol communication is acquired from the server. ### Claim 6 An electrified vehicle system, comprising: a power station configured to be compatible with at least one version of a predetermined communication standard; and an electrified vehicle configured to perform power control including either or both of charging from the power station and power supply to the power station, wherein the electrified vehicle includes a communication unit and a control unit, the communication unit being configured to be compatible with a plurality of the versions of the predetermined communication standard, and the control unit being configured to control the communication unit in such a manner that power control protocol communication between the electrified vehicle and the power station is performed using the predetermined communication standard, the communication unit is configured to acquire information on a result of a past power control protocol communication for each of the plurality of versions, and the control unit is configured to decide the version to be used for the power control protocol communication based on the information of the result.
