The motor/generator is at least partially positioned within the tunnel.

A driveline for a military vehicle includes a driver configured to be positioned between an engine and a transmission. The driver includes a housing, a motor/generator, and a clutch. The housing includes an engine mount configured to couple to the engine and a backing plate configured to couple to the transmission. The motor/generator is disposed within the housing and configured to couple to an input of the transmission. The clutch is disposed within the housing and coupled to the motor/generator. The clutch is configured to selectively couple an output of the engine to the motor/generator.

An electrified military vehicle system includes a military vehicle and a laser system supported by the military vehicle. The military vehicle includes an export power interface, an engine, an axle selectively driven by the engine, and a generator selectively driven by the engine to generate electric power. The generator is configured to provide the electric power at least one of directly to the export power interface or indirectly to the export power interface through an energy storage system. The laser system includes an input interface configured to engage with the export power interface.

A military vehicle includes a passenger capsule including a floor and sidewalls, a door coupled to the passenger capsule, a front module coupled to a front of the passenger capsule, a rear module coupled to a rear of the passenger capsule, and a battery pack coupled to an exterior of the passenger capsule, the door, the front module, or the rear module. The battery pack includes a battery that is removably coupled to the exterior of the passenger capsule, the door, the front module, or the rear module.

Military vehicle with modular battery units

An electrified military vehicle system includes a first military vehicle and the second military vehicle. The first military vehicle includes a prime mover configured to drive the first military vehicle and a first mechanical coupling interface positioned at a rear end of the first military vehicle. The second military vehicle includes an axle, a second mechanical coupling interface positioned at a front end of the second military vehicle where the second mechanical coupling interface is configured to engage with the first mechanical coupling interface to selectively couple the second military vehicle to the first military vehicle, an energy storage system, and a generator coupled to the axle and electrically coupled to the energy storage system. The generator is configured to generate electric power while the axle rotates as the second military vehicle is towed by the first military vehicle to charge the energy storage system.

Convoy operations for electrified military vehicles

A military vehicle including a chassis, a cab mounted to the chassis and defining a rear wall, an engine mounted to the chassis, a transfer case coupled to the engine and including a driven output providing mechanical power to the military vehicle and a generator output, and an electric machine positioned rearward of the rear wall of the cab and coupled to the generator output of the transfer case and generating electrical power.

A military vehicle includes a chassis, a cargo body, and an energy storage system. The chassis includes a passenger capsule having a rear wall. The cargo body is positioned behind the passenger capsule and supported by the chassis. The energy storage system includes a battery housing defining a lower end and an upper end, a battery disposed within the battery housing, a bracket coupled to the battery housing at or proximate the upper end thereof, a lower support supporting the lower end of the battery housing where the lower support is supported by the chassis, and an upper connector extending between the bracket and the rear wall.

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.
