Abstract: An OR circuit 61 of a relay drive unit 60 provides an ON output when at least one of a drive signal output from a battery ECU 52 and a latch signal output from an HVECU 70 is ON signal, while providing an OFF output when both the drive signal and the latch signal are OFF signals. The HVECU 70 switches off the latch signal when the engine operates, while switching on the latch signal when the engine is at stop. When no abnormality of communication with the HVECU 70 is detected and a specified time duration has not elapsed since detection of the abnormality of communication with the HVECU 70, the battery ECU 52 switches on the drive signal. When the specified time duration has elapsed since detection of the abnormality of communication with the HVECU 70, the battery ECU 52 switches off the drive signal.

When shifting of the first operating mode employing only one of the first and second power supplies to the second operating mode employing both the first and second power supplies is started, the controller sets input and output power command values for other of the first and second DC power supplies to be equal to or higher than a lower limit value, and maintains, within a predetermined range, a ratio of the input and output power command values for the first and second DC power supplies, relative to the power demanded by the load.

Abstract: A power supply includes a load, an electric power line connected to the load, first and second DC power supplies which supply electric power to the load, an electric power converter connected between the electric power line and the first and the second DC power supplies, and a controller controlling the electric power converter. The first DC power supply serves for a voltage control, while the second DC power supply serves for an electric power control. The controller sets a difference between an electric power requested by the load and target output electric power of the first DC power supply as target output electric power of the second DC power supply, and compensates the target output electric power of the first DC power supply in accordance with a difference between the actual and the target output electric powers of the second DC power supply.

Upon selection of an operation mode in which the first and second DC power supplies are parallelly connected to the power line for providing the power line with an output from the first DC power supply after DC voltage conversion in the power converter and with an output from the second DC power supply without DC voltage conversion, the controller sets the maximum value of the total power output from the first and second DC power supplies to the power line at the sum of actual power of the first DC power supply and a charge limiting value for the second DC power supply.

Abstract: A converter is capable of using two power sources located on a first side by switching connection of the two power sources between series connection and parallel connection. Under certain conditions, such as when a detected atmospheric pressure is lower than a predetermined value, frequency of use of the two power sources in series connection is reduced in the converter. It is thereby possible to prevent generation of excessive voltage by the power converter.

Abstract: In a vehicle including a charge circuit for carrying out external charging to charge a vehicle-mounted battery with a power supply external to the vehicle, a vehicle ECU. determines that there is an impedance error when a state where a reduction width of an input voltage Vin applied to the charge circuit from the power supply external to the vehicle is exceeding a threshold width ?V continues for a predetermined time, and outputs a first termination instruction to a charger ECU. The charger ECU receiving the first termination instruction causes the charge circuit to stop to terminate external charging. The charger ECU controls the charge circuit such that, when the input voltage Vin falls down to a threshold voltage V1 the current flowing through an external power supply system is reduced to suppress further reduction in the input voltage Vin.

Abstract: A second power storage device is electrically connected to a positive electrode line and a negative electrode line, and electric power for generating a driving force is directly supplied to an inverter section. A converter section supplies electric power received from the inverter section to a first power storage device. Because a backflow prevention circuit is provided, the electric power is not supplied in the direction of the second power storage device at this point. A diode of the backflow prevention circuit is connected between a system main relay and the connection node of a positive electrode line on the positive electrode line branching off from the positive electrode line and connected to the second power storage device. The diode controls the flow of a current from the positive electrode line side toward the second power storage device.

Abstract: A vehicle is a vehicle in which a high-voltage power supply can be charged with electric power from an external power supply. In a travel mode, a main microcomputer (MMC) of a controller outputs a request signal requesting to forcibly turn a plug-in main relay (PIMR) on to a sub-microcomputer (SMC), in order to activate a charging system that is essentially not required to be activated. Upon receiving the request signal, the SMC outputs a signal for turning the PIMR on to the PIMR. If the MMC does not receive electric power from a low-voltage power supply via the PIMR after outputting the request signal, the MMC determines that there is an abnormality in an activation circuit for the charging system, and alerts a user.

Abstract: An ECU detects a rated current that can be supplied from a power supply to a power storage device, based on a pilot signal. If a combination of detected values of a voltage, the rated current and a power supply frequency matches a predefined combination, the ECU executes charging with a voltage, a current and a frequency in accordance with the combination. On the other hand, if it is determined that the combination of the voltage, the rated current and the frequency does not match any one of predefined combinations and if it is determined that the power supply itself is normal, the ECU executes charging by limiting a charging current to a predefined minimum rated current value. If it is determined that the combination of the voltage, the rated current and the frequency does not match any one of predefined combinations and if it is determined that the power supply is abnormal, the ECU prohibits charging.
