An input voltage Vc to a bridge circuit is made variable by making a switching element, which is on a lower side among a plurality of switching elements constituting the bridge circuit, a coil and a capacitor, which constitute a filter, operate as an active filters at the time of charging the battery.

A plug and an outlet are electrically and directly connected, and when a control circuit determines that AC power is input from a power source to a bidirectional insulated DC/AC inverter by voltage V1 detected in a voltage detection circuit, driving of each bridge circuits is inhibited so as not to output AC power outward from the bidirectional insulated DC/AC inverter.

A vehicle starts traveling in an EV travel mode. When a reset request is issued to a first power storage unit, current control is performed to discharge actively the first power storage unit. After time when charging by an external power supply becomes allowed, a discharge current of the first power storage unit to be reset is kept at a constant current value, and a second power storage unit not to be reset is charged with a charge current including at least the discharge current of the first power storage unit. When a distinctive point appears on a battery voltage characteristic of the first power storage unit at a subsequent time, an estimated value of an SOC of the first power storage unit is reset to a predetermined reference value.

An ECU executes a program including the steps of causing a battery pack to discharge when an external power supply is connected to a charger, stopping discharge of the battery pack when a state of charge of the battery pack is reduced to a reset value, and charging the battery pack after the state of charge is reduced to the reset value.

Converters are configured to operate in a normal operation to convert the electric power that is input/output to/from secondary batteries bidirectionally to direct current voltage. In a predetermined mode allowing the secondary batteries to be charged, at least one of the converters does not perform a switching operation and holds on an upper arm element to avoid a switching loss in charging the secondary batteries. An electric power loss caused at the converters in charging the secondary batteries can be reduced, and charging efficiency can be enhanced.

A bidirectional DC/AC inverter includes a power conversion means in connection with an electric storage means, a control means operable to control an operation of the power conversion means, a plug for electrically connecting a power source to the power conversion means, an outlet for electrically connecting a load to the power conversion means, an inhibiting member operable to cover at least the plug to inhibit the power conversion means from being electrically connected to the power source, and a detecting means operable to detect whether the plug is covered or not. The control means inhibits the power conversion means from outputting alternating-current power when the detecting means detects that the plug is not covered by the inhibiting means.
摘要:
A power supply connector (410) is used to supply electric power from a hybrid vehicle (100) equipped with an engine (160) and a motor generator (130, 135) to a device outside of the vehicle (100). When the power supply connector (410) is connected to an inlet (220) of the vehicle (100), the power supply connector (410) outputs a signal for performing a power supply operation while allowing operation of the engine (160) to an ECU (300) of the vehicle (100).
摘要:
A vehicle includes a battery as a power storage device that can be charged and discharged, a booster unit, an inverter, and a motor generator operating as a vehicle driving unit receiving electric power supply from the battery to drive the vehicle, a coupling unit coupling the vehicle with an external power supply for charging the battery from the outside of the vehicle, and a control device performing control related to the battery. The control device determines whether or not a destination is a charging-available place where the battery can be charged from the outside of the vehicle, and if the destination is a charging-available place, performs control related to the battery so that the temperature of the battery is a charging-efficient temperature on arrival at the destination.
