摘要： A vehicular power supply device to be equipped in a vehicle includes an electric storage unit group, an inverter, a driving motor, a converter, an electric device group, a first switch, and a second switch. The electric storage unit group includes first and second electric storage units. The driving motor is to be coupled to the electric storage unit group via the inverter. The electric device group is to be coupled to the electric storage unit group via the converter. The first switch is to be controlled between a state where the first electric storage unit is coupled to the inverter and a state where the first electric storage unit is coupled to the converter. The second switch is to be controlled between a state where the second electric storage unit is coupled to the inverter and a state where the second electric storage unit is coupled to the converter.

摘要： A vehicle power supply includes an electric accumulator pack, an electric motor, first and second switches, an output determiner, and a switch controller. The electric accumulator pack includes first and second electric accumulators. The first and second switches are controlled between on- and off-states. The output determiner determines whether the first electric accumulator is in a first output state or a second output state, and whether the second electric accumulator is in the first output state or the second output state. If at least one of the first electric accumulator or the second electric accumulator is in the first output state, the switch controller controls either one of the first and second switches to the on-state, and the other switch to the off-state. If both the first and second electric accumulators are in the second output state, the switch controller controls both the first and second switches to the on-state.

摘要： An idling stop control device includes an authenticator, a storage, a getting-off detector, and an engine restart permitter. The authenticator is installed in a vehicle, performs authentication via a wireless communication with a mobile device, and repeatedly performs, while the vehicle travels, an authentication operation at predetermined intervals. The storage stores result and time of authentication as the authentication history during travel. The engine restart permitter determines permission or prohibition of restart of the engine in accordance with the authentication history and getting-off information, permits restart of the engine when the authentication is successful and permits, in a case where the authentication fails, restart of the engine when a history of success of authentication has been stored in the storage during travel and the getting-off is not detected after the authentication has been successful.

摘要： A vehicular power supply device includes an inverter, a converter, a driving motor, an electric device group, a first electric storage unit to be coupled to the driving motor via the inverter, a second electric storage unit to be coupled to an electric device group via the converter, an electric power converter, first and second switches, and a switch controller. The electric power converter is provided between the two electric storage units and couples them in parallel with each other. The first switch is provided between the first electric storage unit and the electric power converter and is controllable between on and off states. The second switch is provided between the second electric storage unit and the electric power converter and is controllable between on and off states. The switch controller controls the first and second switches based on a state of charge of the first electric storage unit.

摘要： A power-feed connector disconnection device includes an index value detector, a starting intention determiner, and a lock-releasing unit. The index value detector detects an index value that correlates with a starting intention of a driver to start a vehicle when a power-feed connector is coupled to a power-receiving connector of the vehicle. The starting intention determiner determines a presence or absence of the starting intention of the driver based on the index value detected by the index value detector when the power-feed connector is coupled to the power-receiving connector of the vehicle. The lock-releasing unit is provided in the power-receiving connector and releases a lock between the power-receiving connector and the power-feed connector when the starting intention determiner determines that the driver has the starting intention.

摘要： A vehicular power supply device to be applied to a vehicle includes an electric storage unit group, a charger, first and second switches, and a switch controller. The electric storage unit group includes a first electric storage unit and a second electric storage unit having higher internal resistance than the first electric storage unit. The charger is coupled to the electric storage unit group and charges one or both of the first electric storage unit and second electric storage unit. The first switch is provided between the first electric storage unit and the charger and controlled between an on state and an off state. The second switch is provided between the second electric storage unit and the charger and controlled between an on state and an off state. The switch controller controls the first and second switches based on a temperature of the electric storage unit group.

摘要： A vehicle charging system includes: power supply connectors each coupleable to the power reception connector of a vehicle; a power supply coupled to the power supply connectors and capable of supplying power to at least one of the power supply connectors; a charge completion detector that detects charge completion; a switching unit that, when charge completion in a first vehicle is detected, if a second vehicle is coupled to one of the power supply connectors and is yet to be charged, changes a destination to which the power supply outputs power to the power supply connector coupled to the second vehicle; an unlocking unit that, when charge completion is detected, automatically unlocks the power supply connector that is coupled to a vehicle in which charge completion is detected; and a charge completion indicator that indicates charge completion when charge completion is detected.
