An electric drivetrain for installation in a vehicle chassis. A generator coupled to an engine generates electric power for charging an array of batteries. The vehicle, including components and subsystems, may be powered electrically from the batteries, allowing the engine and generator to be easily replaced or customized for an industry, geographic region, fuel type, or a set of emission requirements. A thermal management system may determine a battery temperature for the set of batteries and cause one or more of a coolant system, a refrigerant system, an exhaust gas system, or an ambient air heat exchanger to add heat to the set of batteries or transfer heat away from the set of batteries.

A hybrid air mobility system is capable of flying a long distance through effective operation of an engine and batteries. The hybrid air mobility system includes a fuselage configured to supply power to a propeller and electric equipment, the fuselage being provided with a duct including an inlet and an outlet so as to circulate air to the engine and the electric equipment; a deflector rotatably installed at the outlet of the duct so as to convert a discharge direction of exhaust gas generated by the engine and cooling air after cooling the electric equipment; and a controller configured to determine whether or not the engine is driven and to control a rotated position of the deflector depending on an amount of driving of the engine so as to selectively adjust movement of the exhaust gas and the cooling air towards the propeller.

A method and apparatus for parking lot metering. The present invention allows multi-space meters to separately manage and control premium parking spaces, such as those for charging electric vehicles or those which supply electric power for engine block heaters in both pay-by-space and pay-and-display systems. Such premium spaces can be managed together over large areas (e.g., a city or region), or may be managed over smaller areas (e.g., the domain of an individual kiosk), or individually per parking space. Management includes pricing, time limits, hours, seasons of operation, and restrictions by vehicle type, and alternative pricing and restrictions for non-premium hours.

A military vehicle including an engine coupled to the chassis for providing mechanical power to the military vehicle, a motor/generator coupled to the engine, and an energy storage system including a battery electrically coupled to the motor/generator. The military vehicle is operable in a silent mobility mode with the engine inactive and the energy storage system providing power to the motor/generator to operate the military vehicle. The motor/generator and the battery are sized such that electrical power generation through engine drive of the motor/generator is greater than the power depletion through operation of the military vehicle in the silent mobility mode. The motor/generator can charge the energy storage system while the military vehicle is driving or stationary.

A power management system includes a sensor interface that receives sensor data samples during operation of a vehicle. A storage device stores the sensor data samples for multiple points in time along a route segment traveled by the vehicle. One or more processors analyze the sensor data samples to detect a historical pattern of the vehicle. The one or more processors determine time efficient operational parameters for the vehicle in response to a destination and an estimated travel time to the destination. The estimated travel time may be based on predicted conditions of the vehicle indicated by the historical pattern. The time efficient operational parameters may be selected to decrease the estimated travel time. At least one of the sensor data samples may include telemetry data.

Vehicles that are capable of connecting to the AC grid are described that comprise a prime mover and at least one motor generator. In one embodiment, a vehicle may be constructed as a plug-in hybrid system and using the powertrain under controller instruction to either place power on an AC power line (to service AC grids) or to draw power from the AC power line to add electrical energy to the batteries on the vehicle. In some aspects, vehicles may test whether the power needed to service the AC power line may be satisfied by the on-vehicle batteries or, if not, whether and how much power to extract from the prime mover. In some aspects, vehicles may have a thermal management system on board to dynamically supply desired heat dissipation for the powertrain, if the powertrain is using the prime mover to supply power to the AC grid.

A military vehicle includes a chassis, a front end accessory drive (FEAD), and circuitry. The chassis includes an engine and an integrated motor generator (IMG). The FEAD includes multiple accessories and an electric motor-generator. The circuitry is configured to operate the military vehicle according to different modes. The circuitry is configured to receive a user input indicating a selected mode of the modes, and operate the chassis and the FEAD of the military vehicle according to the selected mode. The modes include an engine mode and an electric mode. In the engine mode, the engine drives the FEAD and the tractive elements of the military vehicle through the IMG for transportation. In the electric mode, the engine is shut off to reduce a sound output of the military vehicle and the IMG drives the tractive elements of the military vehicle for transportation and the electric motor-generator drives the FEAD.

A vehicle includes an engine block heater, a traction battery, and a controller. The controller, responsive to a temperature being less than a threshold, charges the traction battery with grid energy until a state of charge of the traction battery achieves a charge target. The controller is further programmed to, responsive to the state of charge achieving the target, discharge the traction battery to power the engine block heater until the state of charge falls below a discharge target or the temperature achieves a temperature target. The controller is also programmed to, responsive to the charge falling below the discharge target, charge the traction battery with grid energy until the state of charge achieves the charge target. Additionally, the controller is programmed to, responsive to a temperature achieving a temperature target, inhibit charging and discharging the traction battery.

A hybrid vehicle includes a multi-cylinder engine, an exhaust gas control apparatus, an electric motor, an electricity storage device, and a controller. The controller is configured to control the electric motor so as to cover a driving power shortage resulting from execution of catalyst temperature raising control. The catalyst temperature raising control is control that involves stopping fuel supply to at least one of cylinders of the multi-cylinder engine and enriching air-fuel ratios for the other cylinders than the at least one cylinder.
