An electrified vehicle and method for heating a passenger cabin of an electrified vehicle that may include an internal combustion engine in addition to an electric machine and a traction battery for supplying the electric machine control an electric heating element to store thermal energy while the vehicle is connected to an external power source that is also used to charge the traction battery, and to extract stored thermal energy during operation of the vehicle with the electric heating element turned off to extend the electric driving range of the vehicle while also providing heat to the passenger cabin. The electric heating element may positioned and controlled to heat one or more elements directly by mechanical contact, or indirectly by heating a circulating liquid coolant to a temperature above a current or anticipated external ambient temperature.

Plug-in electric vehicle and method for heating a passenger cabin

A vehicle includes an oil-cooling system arranged to circulate oil through an electric machine and an oil-to-coolant heat exchanger. A coolant system has conduit arranged to circulate coolant through an inverter, a heater core, and the heat exchanger. A climate control system is arranged to circulate an airstream through the heater core to heat a passenger cabin with waste heat from the electric machine and the inverter.

System and method for heating passenger cabin with combination of power electronics and electric machine waste heat

An electrified vehicle according to an exemplary aspect of the present disclosure includes, among other things, a battery including a first strand of cells and a second strand of cells, an electric machine selectively powered by the battery, and at least one auxiliary component selectively powered by the battery. The battery is configurable such that the at least one auxiliary component is able to draw power from the first strand of cells but not the second strand of cells. A method is also disclosed.

Electrified vehicle with splittable battery and associated method

A exhaust-gas heat management system includes a catalytic converter in the exhaust-gas train of an internal-combustion engine, a cover enclosing the catalytic converter, and thereby realizing a cavity for holding a latent-heat storage PCM, at least two fluid connections between the cavity and the collecting vessel, and a pump device for activating and deactivating a PCM circuit between the cavity and the collecting vessel by means of the fluid connections. A method comprises determining an operating state of the internal combustion engine, determining the catalytic converter temperature, determining the PCM temperature, activating the PCM circuit if the PCM temperature is above a phase transition temperature of the PCM, and the internal combustion engine is in a switched-on operating state or the internal combustion engine is in a switched-off operating state and the catalytic converter temperature is below a light-off temperature of the catalytic converter.

Method and system for exhaust-gas heat management

A vehicle includes a passenger cabin, an inverter, and a coolant system having conduit arranged to circulate coolant through the inverter and an evaporator. A refrigerant system includes a condenser and conduit arranged to circulate refrigerant through the condenser and through the evaporator to absorb heat generated by the inverter. A climate control system is arranged to circulate an airstream through the condenser and into the cabin to heat the cabin.

System and method for heating passenger cabin with combination of inverter waste heat and refrigerant

A vehicle includes an inverter, a climate control system, and a coolant system. The climate control system includes a housing, and a heater core and an electric heater disposed within the housing. The coolant system includes conduit arranged to circulate coolant through the inverter and the heater core. The inverter is disposed upstream of the heater core.

The disclosure relates to an assembly that cools a traction battery of a vehicle, in particular a hybrid electric vehicle. The assembly can include at least one fuel tank and at least one traction battery that is arranged outside the fuel tank and is thermally connected to the fuel tank. The assembly can further include at least one cooling rib that is arranged inside the fuel tank. The cooling rib can be thermally connected to a connection portion of the fuel tank, which is thermally connected to the traction battery and is constructed in such a manner that it extends almost completely or completely as far as a base wall portion of the fuel tank. The fuel tank can be arranged to be lower than the connection portion.

This disclosure relates to an assembly that cools a traction battery of a vehicle, in particular a hybrid electric vehicle. The assembly can include at least one fuel tank, and at least one traction battery that is arranged outside the fuel tank and is thermally connected to the fuel tank. The assembly can further include at least one fuel pump that is arranged in the fuel tank and at least one fuel line that is connected and/or can be connected to a pressure side of the fuel pump. A connection portion of the fuel tank is thermally connected to the traction battery. Fuel can be used to cool the connection portion, which cools the traction battery.

Assembly and method for cooling a traction battery of a vehicle using fuel

The disclosure relates to an assembly for a vehicle, in particular for a hybrid electric vehicle. The assembly includes at least one fuel tank having the form of a saddle tank. The assembly further includes at least one traction battery that is arranged outside the fuel tank and is thermally connected to the fuel tank, and at least one fuel pump arranged in the fuel tank. The fuel pump can convey a fuel from within the fuel tank to an internal-combustion engine of the hybrid electric vehicle. To provide a cooling system for the traction battery, the traction battery can be thermally connected to an active tank portion of the fuel tank, in which the fuel pump is arranged. The traction battery can be connected to the active tank portion via a bridge portion of the fuel tank, which is connected in a communicating manner to a passive tank portion of the fuel tank. Fuel in the passive tank portion can be conveyed into the active tank portion.

A method includes controlling an electrified vehicle by modifying a state of charge (SOC) window associated with an energy storage device of the electrified vehicle in response to a reverse driving event or a trailer towing event.

System and method for improving reverse driving capability of electrified vehicles

A vehicle system includes a controller that is programmed to, in response to a speed differential between the vehicle and a forward detected object, decelerate the vehicle at a first rate during a first period via regenerative braking alone and decelerate the vehicle at a second rate during a second period, following the first period, to reduce a distance to the forward detected object from an initial distance to a minimum distance.

Regenerative braking method

A vehicle system includes a voltage converter configured to electrically isolate and convert power transferred between high voltage (HV) and low voltage (LV) busses, and a controller configured to, responsive to regenerative power exceeding a charge power limit of a traction battery receiving charge via the HV bus, increase an output voltage of the converter to initiate transfer of some of the regenerative power to an auxiliary battery connected with the LV bus.
