The present disclosure provides an electric vehicle comprising a chassis, a front axle and a rear axle spaced apart and coupled to the chassis, and a battery frame assembly coupled to the chassis between the front axle and the rear axle. The battery frame assembly comprises a plurality of transversely extending members and a plurality of longitudinally extending members, wherein the plurality of transversely extending members and the plurality of longitudinally extending members define a matrix of battery pack receptacles configured to receive at least one battery pack. The battery frame assembly is configured to deflect torsionally in response to torsional deflection of the front axle relative to the rear axle.

Aerodynamic wheel covers may include a hub assembly coupled with a hub of a large vehicle, such as a truck. A base assembly may be coupled to the hub assembly, and a disk assembly may be coupled with the base assembly such that removal and installation of the disk assembly may be accomplished without tools.

A modular electric axle head assembly for a vehicle, including a gear assembly including a gear assembly housing defining a hollow portion therein, a first gear shaft having a first gear, a second gear shaft having a second gear and a third gear, wherein at least a portion of the second gear is drivingly connected to the first gear and the third gear, and at least a portion of the gear assembly is disposed within the hollow portion of the gear assembly housing; a motor assembly having an output shaft that is drivingly connected to at least a portion of the gear assembly; and a first mounting assembly including a portion integrally connected to the modular electric head assembly and a portion integrally connected to a support member of the vehicle, wherein at least a portion of the third gear is drivingly connected to a pair of drive shafts.

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.

A drive axle system that includes first and second wheel end assemblies, a support structure, and an electric motor. A support structure supports the first and second wheel end assemblies and the electric motor. The electric motor has a rotor that is rotatable about a rotor axis. The rotor axis is disposed below a wheel axis.

The present disclosure relates to energy storage mounting system for an energy storage system of a vehicle, the mounting system comprising: a vehicle mounting member connectable to a longitudinal frame of the vehicle, the vehicle mounting member comprising an elongated portion arranged to, when the vehicle mounting member is attached to the longitudinal frame, extend away from the longitudinal frame, wherein the elongated portion comprises a recess at an outer end portion thereof; and a battery mounting member connectable to the energy storage system, the battery mounting member comprising a connecting portion, wherein the connecting portion is movable between a disconnected state, in which the connecting portion is positioned at a distance from the elongated portion of the vehicle mounting member, and a connected state, in which the connecting portion is positioned in the recess for connecting the battery mounting member to the vehicle mounting member.

A mounting structure for a series of electric battery packs (21); such packs get mounted between the two lateral chassis rails (11, 12) of a medium or heavy-duty electric vehicle. The battery packs get inserted through either the forward-facing or rear- facing ends of the chassis frame. Such chassis frame is created by joining a set of double up frame rails (11, 12) together with U- shaped cross members (32), allowing access to the interior of the chassis frame, and allowing a simplified removal and replacement of batteries for maintenance purposes.
