A power supply connector () is used to supply electric power from a hybrid vehicle () equipped with an engine () and a motor generator () to a device outside of the vehicle (). When the power supply connector () is connected to an inlet () of the vehicle (), the power supply connector () outputs a signal for performing a power supply operation while allowing operation of the engine () to an ECU () of the vehicle ().

Power supply connector, vehicle and control method for vehicle

An electric vehicle charger includes: a first winder unit and a second winder unit for winding and holding a charging cable having a charging connector at its end portion; and a body unit for arranges the first winder unit and the second winder unit with the distance between the first winder unit and the second winder unit set longer than the diameter of the charging cable, wherein the charging cable passes between the first winder unit and the second winder unit, and the charging cable is fixed before passing between the first winder unit and the second winder unit.

Electric vehicle charger

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.

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.

Power supply system and electric powered vehicle including power supply system, and method for controlling power supply system

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.

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.

Electric system, charging device and charging method for electric system for discharging of a power storage mechanism for resetting a state of a charge

In an electric system including a first converter and a second converter connected in parallel, an ECU executes a program including a step of selecting a charging mode for a first battery pack connected to the first converter and a charging mode for a second battery pack connected to the second converter, and a step of controlling a charger connected to the first battery pack, the first converter and the second converter to charge the first battery pack and the second battery pack in the selected charging modes.

Control device and control method for electric system

A power supply apparatus for a vehicle includes first and second batteries provided electrically in parallel to main loads, a boost converter provided between the first battery and the main loads, a boost converter provided between the second battery and the main loads, an auxiliary battery, a DC/DC converter, and an auxiliary load driven by power from the auxiliary battery or DC/DC converter. The controller determines charging currents or discharging currents for the batteries reflecting variations in a current flowing through the auxiliary load. Accordingly, a power supply apparatus for a vehicle can thus be provided in which imbalance between charging/discharging currents for a plurality of power storage devices is reduced.

Power supply apparatus for vehicle

A power supply system for a vehicle includes: batteries; motor generators operating as rotating electrical machines driven by electric power in the batteries when the vehicle is running, and constituting a first charger when the batteries are charged by electric power received from a source external to the vehicle and; an inlet receiving the electric power supplied from the external source; a second charger receiving the electric power supplied from the external source and charging the batteries; and a control device selecting one of the first and second chargers and performing control for converting the electric power supplied from the external source to the inlet into charging electric power using the selected charger. Thus, a power supply system for a vehicle that is chargeable from various power supplies at the time of charging and has reduced charge loss can be provided.

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.

Bidirectional DC/AC inverter

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 Vdetected 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.

Bidirectional insulated DC/AC inverter

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.
