摘要:
A converter ECU Obtains a temperature increase start signal indicating start of temperature increase of a power storage unit from each sensor and ECU provided in a vehicle. In addition, the converter ECU obtains allowable electric power of the power storage unit from a battery ECU and obtains a power storage unit temperature from a temperature detection unit. When any of the obtained power storage unit temperatures is lower than a corresponding temperature lower limit value, the converter ECU generates a temperature increase instruction for the power storage unit of which temperature is lower than the corresponding temperature lower limit value, based on the temperature increase start signal. In addition, the converter ECU selects one control mode from among a plurality of control modes set in advance, based on the generated temperature increase instruction, and sets that mode as the control mode for a converter.

Sensors detect physiological data of an occupant of a vehicle. A storage device accumulates the physiological data of the occupant detected by each of the sensors for storage. When a charging cable for charging a power storage device in a motive power output device is connected, a vehicle ECU transmits the physiological data stored in the storage device to an element external to the vehicle through electric power lines and the charging cable, employing a modem.

Generation power determining unit specifies efficiency characteristic based on identification ID of each vehicle. Generation power determining unit determines a power generation mechanism or mechanisms to be operated such that amount of power consumption by the power generation mechanism or mechanisms as a whole is minimized. By dividing power ΣPg* necessary for charging an electric storage unit that is in a low-charge state by the number of mechanisms to be operated (for example, 2 or 3), fuel consumption efficiency corresponding to generation power to be shared by each power generation mechanism in each case is obtained. There is a relation of η(½)>η(⅓) and, therefore, it can be understood that two power generation mechanisms are to be operated to minimize total amount of fuel consumption. Generation power determining unit transmits a power generation instruction to vehicles that correspond to the determined two power generation mechanisms.

A converter ECU controls a converter to transmit an electric power between a power storage device and a power storage unit through a main positive bus line and a main negative bus line during temperature rise control of the power storage device. Specifically, converter ECU sets a target voltage of the converter to a second voltage value lower than a first voltage value when a voltage value reaches the first voltage value, and sets the target voltage of the converter to the first voltage value when the voltage value reaches the second voltage value.

A data acquiring unit (122) acquires external factor data such as day of the week, date and time, or weather together with electric power data in a house, and stores the data in a storage unit (114). A classification/learning unit (124) reads the electric power data and the external factor data stored in the storage unit (114), and classifies/learns the read data. A scheduling unit (126) predicts a house power demand on the basis of the classified/learned data, and plans the charge/discharge of a vehicle according to the result of prediction. A command generating/outputting unit (128) generates a charge/discharge command of the vehicle according to the charge/discharge schedule.

When a torque command value from an external ECU is within a predetermined variation width, a control unit generates a signal and outputs the signal to a voltage command calculation unit so that electrostatic energy stored in a capacitor is kept at a predetermined threshold value or larger. Based on the signal, the voltage command calculation unit determines a target voltage of a voltage step-up converter that corresponds to a terminal-to-terminal voltage of the capacitor. In contrast, when the torque command value is out of the predetermined variation width, the control unit determines electric power to be supplied from a DC power supply to an inverter for allowing electric power to be supplied predominantly from the capacitor rather than from the DC power supply and outputs a signal. Based on this signal, the voltage command calculation unit determines the target voltage.

A motive power outputting apparatus includes motor generators, inverters, and a transformer. The motor generator includes a three-phase coil, and the motor generator includes a three-phase coil. The inverter allows an in-phase AC current to pass through an U-phase coil, a V-phase coil and a W-phase coil of the three-phase coil. The inverter allows an in-phase AC current, which has a phase being inverted relative to that of the in-phase AC current passing through the three-phase coil, to pass through an U-phase coil, a V-phase coil and a W-phase coil of the three-phase coil. The transformer converts an AC voltage generated in a primary coil and outputs a commercial-power-source AC voltage to terminals.

An electric motor vehicle includes a battery that serves as a driving source for generating electric power, a pair of positive and negative electrode portions respectively connected to a positive electrode and a negative electrode of the battery, a resistor formed of a resistive material, and a first and a second contact portions connected to the resistor. The first and the second contact portion face the positive electrode portion and the negative electrode portion, respectively. The resistor is kept insulated from the battery in a normal operation state of the electric motor vehicle. At least one of the positive electrode, the first contact portion, the negative electrode and the second contact portion is displaced owing to an external force applied to the electric motor in an abnormal operation state such that the electrodes are in contact with their respective contact portions and the positive electrode and the negative electrode are short circuited in an abnormal operation state.
