PROBLEM TO BE SOLVED: To reduce wasteful power consumption while power is supplied to a house from a vehicle and improve user convenience.SOLUTION: After a disaster occurs, for example, a vehicle 100 supplies electric power to a power distribution board 302 of a house 300 through a V2H stand 400. Electric power is distributed to each of power supply systems 351, 352, 353 arranged in the house 300 from the power distribution board 302. The power distribution board 302 has branch breakers 311, 312, 313 and a controller 320. The branch breakers 311, 312, 313 are provided to each of the power supply systems 351, 352, 353. The branch breakers 311, 312, 313 can block the power supply systems 351, 352, 353 electrically. When total WH0 of the electric power amounts WH1, WH2, WH3 to be supplied to each of the power supply systems 351, 352, 353 is larger than electric power amount WHS which can be supplied to the power distribution board 302 from the vehicle 100, each of the branch breakers 311, 312, 313 is controlled so that power is blocked orderly from the power supply system having a predetermined lower priority.

PROBLEM TO BE SOLVED: To provide a power supply that properly determines which of charging to the power supply or power supplying from the power supply to perform, when connected to the power supply.SOLUTION: A power supplying connector 10 uses a signal route for transmitting the signal which transmits information to determine a fitting state of a charging connector in accordance with a J1772 standard by SAE and a connection part, as the signal route for transmitting the signal, in which a value is changed depending on a connected state, and the value is changed depending on an indication permitting power supply from a vehicle to a power supply target. The signal route is formed as a closed system. The vehicle 20 can be fed with power by being coupled with the power supply target through the power supplying connector, and uses the signal route in accordance with the J1772 standard by SAE, as the signal route for transmitting the signal, and forms the signal route as the closed system.

PROBLEM TO BE SOLVED: To provide an engine stop determining device which can optimize determination of an engine stop in accordance with a condition of a cooling system, and a method for determining the engine stop. SOLUTION: The cooling system of an engine 1 includes a first cooling water passage L1 through which coolant circulates between a water jacket of an engine body 11 and a heater core 12, a second cooling water passage L2 through which the coolant circulates between an exhaust heat recovery device 13 and the heater core 12, a first temperature sensor D7 provided on the first cooling water passage L1, and a second temperature sensor D8 provided on the second cooling water passage L2. An engine control section 91 performs determination of the engine stop based on coolant temperature detected by the first temperature sensor D7 and the second temperature sensor D8, and uses the coolant temperature detected by the first temperature sensor D7 or the coolant temperature detected by the second temperature sensor D8 when performing the determination of the engine stop, depending upon whether a heater unit including the heater core 12 is in operation or not in operation.

PROBLEM TO BE SOLVED: To provide a battery protection device capable of preventing overvoltage of a battery by reliably consuming excessive power even if the excessive power is generated in regeneration. SOLUTION: The battery protection device includes: a battery; an electric load; and a control means. The battery charges regenerative power to be supplied. The electric load consumes part of the regenerative power supplied to the battery to prevent overvoltage of the battery. The control means controls the regenerative power supplied to the battery and the electric load. The control means sets a target upper limit output value of the regenerative power at a value smaller by a predetermined value than the power consumption capability of the electric load.

PROBLEM TO BE SOLVED: To provide a power supply system with a simpler configuration, having a circuit capable of storing power generated by a load circuit when an energy storage device is in an overcharged state. SOLUTION: The power supply system 10 includes: an energy storage device 12 connected to a load circuit having a rotary electric machine; an overcharge determining means for determining whether the energy storage device 12 is in an overcharged state by charging executed to the energy storage device 12 from the load circuit; a voltage step up/down circuit operating when it is determined that the energy storage device 12 is in an overcharged state; and a capacitor for charging power from the load circuit by the operation of the voltage step up/down circuit and supplying the charged power to at least either the energy storage device 12 or the load circuit.
