  • Control device for prompting battery diagnosis and vehicle having such control device
    Patent number: 12606192
    Abstract: ECU (control device) includes a processor that estimates a full charge capacity of the power storage device, a RAM (first memory) that stores the full charge capacity estimated by the processor, and a communication unit that communicates with a HMI device (information terminal) of electrified vehicle. The auxiliary battery is mounted on electrified vehicle so as to be electrically disconnected from electrified vehicle. When the elapsed time from the point in time when electrified vehicle was last activated (first point in time) to the point in time when electrified vehicle was activated this time (second point in time) is larger than a predetermined value, the communication unit transmits a notification prompting HMI device to diagnose the power storage device.
