    Abstract: A power supply apparatus of a vehicle includes: an engine and a first MG; a battery; a converter stepping up a voltage of the battery and supplying the stepped-up voltage to an inverter of the vehicle; and a control device controlling the converter in a continuous voltage step-up mode in which the converter is continuously operated and an intermittent voltage step-up mode in which the converter is intermittently operated. The control device estimates an SOC of the battery based on battery current IB flowing into and out of the battery, and forces the battery to be charged by the engine and the first MG when an estimate value of the SOC is lower than a predetermined lower limit. The control device suppresses an operation of the converter in the intermittent voltage step-up mode to a greater extent as the estimate value of the SOC is closer to the lower limit.

    Abstract: The present invention is intended to discriminate between a battery voltage sensor and the input voltage sensor of a converter for abnormality, without stopping the step-up operation of the converter. A voltage conversion device is provided with a battery, a converter, a battery voltage sensor, a voltage sensor for detecting the input voltage of the converter, a current sensor for detecting a reactor current, and a control unit. The control unit determines the abnormality of the battery voltage sensor or the input voltage sensor on the basis of an estimated value of input voltage calculated based on the reactor current, the input voltage of the converter and a battery voltage, without stopping the step-up operation of the converter.

    Abstract: A hybrid vehicle includes a battery, a boost converter, a battery temperature sensor, a battery current sensor, a high-voltage sensor, and a control section. The control section includes an intermittent boosting operation program which stops the boost converter when a temperature of the battery is equal to or higher than a predetermined temperature and when an absolute value of a battery current is within a range of ±I0 and which restarts the boost converter when an actual boosted voltage is outside a range from VH2 to VH4, and a threshold switching program that switches the threshold range to ±I2 that is wider than the range of ±I0 and switches the range from the threshold VH2 to the threshold VH4 to a wider range from a threshold VH3 to a threshold VH5 when the battery temperature is lower than the predetermined temperature.

    Abstract: An electrified vehicle includes a drive device including an alternating current motor and an inverter that drives the alternating current motor, a control device that controls the drive device, and a heat transfer device that transfers heat of the drive device to a heating target. When a predetermined heat requirement condition transferred to the heating target is satisfied, the control device executes loss increase control to control the drive device so that the power loss increases compared to a case where the heat requirement condition is not satisfied. When an index value regarding a rotation speed of the alternating current motor is less than a first threshold, the loss increase control includes first control to make a d-axis current of the alternating current motor larger than a reference d-axis current, which is the d-axis current when the heat requirement condition is not satisfied.
