Abstract
An electric powered vehicle may include a battery ECU housed in a battery pack and a vehicle ECU mounted on a vehicle body and communicably connected to the battery ECU. The vehicle ECU may be configured to transmit first and second identification data for detecting communication disruptions to the battery ECU. The battery ECU may be configured to: when the battery ECU receives both the first and the second identification data, determine that the battery ECU is communicably connected to the vehicle ECU and enable a predetermined mutual monitoring function for the vehicle ECU; and when the battery ECU receives the first identification data but does not receive the second identification data, determine that the battery ECU is communicably connected to another ECU other than the vehicle ECU and disable the mutual monitoring function for the vehicle ECU.
