1. A vehicle management method comprising:
obtaining, by an electronic control unit (ECU), a first state-of-health (SOH) information that indicates a degree of deterioration of a power storage device of a vehicle based on charge data on the power storage device measured by a battery sensor while the vehicle is executing external charge of the power storage device using power supplied externally;
obtaining, by the ECU, a second SOH information that indicates the degree of deterioration of the power storage device based on history data recorded in the vehicle when the vehicle is not executing external charge of the power storage device, the history data including at least one of temperature, voltage, current, or state of charge of the power storage device;
determining, by the ECU, whether the history data has been tampered with by comparing the first SOH information and the second SOH information; and
in response to determining that the history data has been tampered with, deleting a tampered portion of the history data stored in a memory of the vehicle.
