Original Abstract Submitted
The display system includes an instrument panel, a battery, a current sensor, and an ECU. The battery stores electric power for traveling of the vehicle. The current sensor detects a charge/discharge current of the battery. ECU calculates SOC of the battery according to the current sensor. SOC includes a control SOC used for charge/discharge control of the battery, and a display SOC displayed on the instrument panel and calculated according to the control SOC. When the index value indicating the degree of decrease in the calculation accuracy of the control SOC exceeds the threshold value, ECU starts a calculation process of calculating the display SOC lower than the control SOC.
