Abstract
A power system includes: a first power circuit, having a first battery; a second power circuit, having a second battery, wherein a used voltage range of the second battery with respect to a closed circuit voltage overlaps with the first battery, and a static voltage of the second battery is lower than the first battery; a voltage converter, converting a voltage between the power circuits; a power converter, converting power between the first power circuit and a driving motor; and a management ECU and a motor ECU, operating the power converter based on required power. The management ECU and the motor ECU calculates limit power with respect to output power of the first battery based on an internal state of the second battery, and operates the power converter so that the output power of the first battery does not exceed the limit power.
