Abstract
A vehicle diagnostic system diagnoses a vehicle having a battery mounted thereon. The vehicle diagnostic system includes an instrument panel for showing a capacity retention of the battery, and an ECU that calculates the capacity retention to be displayed on the instrument panel. The ECU measures the full charge capacity of the battery each time external charging is completed, and, based on a result of the measurement, updates a capacity deterioration curve indicative of changes in over time of the capacity retention. When a display request for showing the capacity retention on the instrument panel is generated, the ECU calculates the capacity retention when the display request is generated by referring to the updated capacity deterioration curve.
