The battery pack is provided with a fifth wheel coupling member that removably couples the battery pack to a fifth wheel of a vehicle. The actuator is mounted onto the vehicle, removably couples to the battery pack, and lifts the battery pack to remove the battery pack from the fifth wheel.

A control system configured to control electrical power distribution of a vehicle formation is provided. The vehicle formation includes a gateway vehicle comprising a gateway prime mover for propelling the gateway vehicle, and a target vehicle comprising a target electric motor for propelling the target vehicle. The gateway vehicle includes a charging component electrically connectable to a charge surface along a road operable by the vehicle formation, the gateway vehicle further comprising a power distribution unit connected to the charging component and the target vehicle. The control system includes control circuitry connected to the gateway vehicle, the target vehicle and the power distribution unit, the control circuitry being configured to receive a signal indicative of a current energy requirement for the gateway vehicle and the target vehicle; and control, based on the current energy requirement, the power distribution unit to distribute electric power within the vehicle formation.

Methods and associated systems for autonomous package delivery utilize a UAS/UAV, an infrared positioning senor, and a docking station integrated with a package delivery vehicle. The UAS/UAV accepts a package for delivery from the docking station on the delivery vehicle and uploads the delivery destination. The UAS/UAV autonomously launches from its docked position on the delivery vehicle. The UAS/UAV autonomously flies to the delivery destination by means of GPS navigation. The UAS/UAV is guided in final delivery by means of a human supervised live video feed from the UAS/UAV. The UAS/UAV is assisted in the descent and delivery of the parcel by precision sensors and if necessary by means of remote human control. The UAS/UAV autonomously returns to the delivery vehicle by means of GPS navigation and precision sensors. The UAS/UAV autonomously docks with the delivery vehicle for recharging and preparation for the next delivery sequence.

There is provided a truck, comprising a cab and a plurality of storage tanks secured behind the rear of the cab, wherein the storage tanks are configured to contain hydrogen gas. An energy conversion system is configured to receive hydrogen gas from the storage tanks and to convert the chemical energy of the hydrogen into mechanical or electric energy. A cooling arrangement is configured to cool the energy conversion system. A wall is provided behind the cab and laterally of the storage tanks, the wall having its main extension in a vertical plane, wherein said wall houses at least a part of said cooling arrangement.

Disclosed in embodiments of the utility model is a tractor power supply system, used for supplying power to a power system of a tractor. The tractor power supply system is provided above or below a transport trailer connected to the tractor. The tractor power supply system is provided above or below the transport trailer, and the tractor power supply system can be configured with battery modules of different capacities according to use conditions of the tractor by utilizing the characteristic of a large installation space of the transport trailer, thereby ensuring the endurance mileage and the working time of the tractor.

The present invention relates to an electric power generating system for vehicles. The system includes at least one wind turbine positioned to capture incoming air which is coupled to a wind generator for converting into electric power. The system has solar panels installed on the exterior surface of the vehicle such as trailer of a semi-truck for absorbing solar energy and converting into electric power. The electric power produced by the wind generator and the solar panels is stored in a battery pack for providing electric power to the electric battery of the vehicle. An emergency generator provides electric power to the vehicle when the power of both the electric battery and the battery pack is insufficient. The system slows down the depletion of battery charge, thus enabling the vehicle to stay on the road for a longer duration and improves overall charging experiences for the electric vehicle.

A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a truck, a tractor unit, a trailer, a tractor-trailer configuration, at a tandem, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

Multi-mode personal transportation and delivery devices and methods of use are disclosed herein. A device can include a communications interface, the communications interface configured to provide vehicle-to-everything communications, a device controller comprising: a processor; and a memory for storing instructions, the processor executing the instructions to: receive a first message from a service provider that the transportation device is to relocate to a location based on user demand; and activate a redistribution mode to cause the transportation device to autonomously navigate to the location.
