摘要:
In an electrical powered vehicle including a control device for generating an input/output power command value for a power storage device and a control device for controlling a power conversion device and a rotating electric machine, provided separately, when there is a sudden change in the rotational speed of a rotating electric machine, the input/output power command value of a power storage device intrinsically set by an HV-ECU is corrected corresponding to the change in the rotational speed of the rotating electric machine by a control device MG-ECU detecting the rotational speed of the rotating electric machine, without having to wait for modification of the input/output power command value from the HV-ECU. Accordingly, there can be prevented excessive charging and excessive discharging of a power storage device induced by delay in modifying the input/output power command value caused by transmission delay between control devices when the rotational speed of the rotating electric machine suddenly changes.

A power supply system that supplies electric power to a load includes a first power storage device, a second power storage device, a power line for transmitting electric power input and output to and from the load, a converter for executing bidirectional DC voltage conversion between the first power storage device and the power line, and a switch connected between the second power storage device and the power line. When the switch is OFF, the control device performs voltage control of the converter so that a voltage value of the power line becomes a voltage command value, and when the switch is ON, the control device performs current control of the converter so that a current value of the first power storage device becomes a current command value.
摘要:
Commercial AC voltage applied to an input terminal (90) from a commercial power supply external to the vehicle is boosted by a transformer (86) to a voltage level higher than the voltage (VB) of an electricity storage device (B) to be applied to neutral points (N1, N2). In a charging mode of the electricity storage device (B) from a commercial power supply, all npn transistors of an inverter (20, 30) are turned off. The AC voltage applied to the neutral points (N1, N2) is rectified by an anti-parallel diode of the inverter (20, 30) to be supplied onto a power supply line (PL2). A boost converter (10) controls the charging current from the power supply line (PL2) towards the electricity storage device (B).
摘要:
An AC command voltage obtained by compensating a reference value of a commercial AC voltage output from a multiplication unit using an FB control unit is multiplied by k (0≦k≦1) by a multiplication unit and output to a first inverter control unit, and the remaining part is output to a second inverter control unit. The first and second inverter control units generate signals, based on command voltages obtained by superposing the AC command voltage from an AC output control unit on respective phase command voltages.

A power supply device for a vehicle includes a battery (B1) which serves as a first power storage device, a battery (B2) which serves as a second power storage device, a vehicle load, a selection switch (RY0) which selects one of the first and second power storage devices and connects the selected power storage device to the vehicle load, and a control device (60) which, when a current flowing through the selection switch (RY0) is larger than a prescribed value, controls the vehicle load so that the current flowing through the selection switch (RY0) is made smaller than the prescribed value, and switches the selection switch. Preferably, when the control device (60) switches the selection switch (RY0), the control device controls inverters (20, 30) to achieve a balance between electric power generated in a first motor generator (MG2) and electric power consumed in a second motor generator (MG1).
摘要:
When it is determined that an electric storage is to be charged from a commercial power source, a controller sets a control target of a voltage of a power line to be controlled by a boost converter, based on a voltage of the commercial power source. Specifically, the controller sets the control target of the voltage to a level approximately equal to the crest value of voltage. Then, the controller outputs an input permission command to a relay circuit, and controls inverters to execute charging of the electric storage.

A vehicle preferential treatment system includes a controller mounted in a hybrid vehicle, and a server performing wireless communications with the controller. The controller estimates an SOC of an electric storage (not shown) and transmits the SOC to the server. When the SOC of the electric storage exceeds a reference level, the server gives a preferential treatment to the hybrid vehicle. Then, information on the preferential treatment is transmitted from the server to the controller, and is displayed on a display unit of the controller.
摘要:
At the time of charging a power storage device from a commercial power supply, electric power from the commercial power supply is applied to a neutral point of each of first and second motor generators. A rotation preventing control unit (222) determines one phase to be subjected to switching control in the first inverter, based on a rotation angle (θ1) of the first motor generator. Further, rotation preventing control unit (222) calculates torque generated in the first motor generator, generates a torque control value for canceling out the torque, and outputs the value to a phase voltage operating unit (214) for motor control.
