An EHC is configured to electrically heat a catalyst that purifies exhaust gas from an exhaust path of an internal combustion engine mounted on an electrically-powered vehicle, when a current passes through the EHC. A charger converts AC electric power supplied from an external power supply to a charging port into charging power of a power storage device by a power conversion path including an insulating transformer. The EHC is electrically connected to power lines which are provided on the primary side of the insulating transformer on the power conversion path, and to which a DC voltage is output. In a case where the EHC is operated when the vehicle travels, the charger converts the electric power from the power storage device into the DC voltage output to the power lines connected to the EHC, by a part of inverse conversion of power conversion at the time of external charging.

Some embodiments include a system. The system includes a conduit system having a conduit system volume. The conduit system can convey a fluid through the conduit system volume of the conduit system. The system also includes at least one pumping mechanism operable to drive the fluid through the conduit system volume, at least one turbine operable to extract energy from the fluid conveyed by the conduit system and driven by the pumping mechanism(s), and at least one generator coupled to the turbine(s) and operable to generate electricity from the energy extracted by the turbine(s). The pumping mechanism(s) are configured to be powered by a first portion of the electricity and the system makes a second portion of the electricity available to one or more electrical loads. Other embodiments of related systems and methods are also disclosed.

A vehicle is a hybrid vehicle including an engine driven by fuel, and the vehicle includes a motor-generator driven by electric power and a charge plug to which a connector is removably connected, the charge plug being capable of at least one of being supplied with electric power from the connector and supplying electric power to the connector. An engine is arranged to be offset toward one side surface and the charge plug is provided in the other side surface.

A non-contact power reception device includes a load such as a power storage device identified as a subject of power feeding, and a secondary self-resonant coil receiving electric power to be supplied to said load from an external primary self-resonant coil. The secondary self-resonant coil is configured so as to be switchable between a first state and a second state. The first state is selected in a power reception mode in which the secondary self-resonant coil is magnetically coupled with the primary self-resonant coil through resonance of a magnetic field. The second state is selected in a power non-reception mode in which the magnetic coupling of the secondary self-resonant coil with the primary self-resonant coil through resonance is weaker than in the first state.

A control device, when performing a reallocation control, makes the decrease gradient of regeneration braking force in a first period in which the amount of decrease in a basal fluid pressure from a reference basal fluid pressure is less than a specified amount of decrease greater than the decrease gradient of the regeneration braking force in a second period in which the amount of decrease in the basal fluid pressure is not less than the specified amount of decrease.

A hybrid battery system of an automotive vehicle provides power to various features without running an internal combustion engine.

A charge-discharge control device charges a power storage device when the charge-discharge control device acquires no warming-up operation command. The charge-discharge control device, when the charge-discharge control device acquires the warming-up operation command, performs warming-up operation by repeated alternatingly charging the power storage device and discharging the power storage device via a first discharger. When a determiner determines during the warming-up operation that an amount of power discharged via the first discharger does not satisfy a criterion, the charge-discharge control device performs the warming-up operation by repeated alternatingly charging the power storage device and discharging the power storage device via a second discharger.

Disclosed is a method for driving an range extending system for a motor vehicle equipped with an electric motor (2) adapted to be supplied with electric current by a traction battery (3), the range extending system including an range extender (1) that can be activated to supply the traction battery and/or the electric motor with electric current and a cooling circuit (10) for the range extender, in which provision is made to acquire a state of charge of the traction battery and, if the state of charge is below a charge threshold, to activate the range extender. Additionally, the charge threshold has a variable value, which is a function of an outside temperature of the air outside the motor vehicle.
