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.

An electrified vehicle includes a front subframe, a rear subframe, and a body that connects the front subframe to the rear subframe so that forces acting on the front subframe and the rear subframe are transmitted through the body. The vehicle also includes a housing coupled to an underside of the body between the front subframe and the rear subframe. An energy storage system is enclosed in the housing and includes a battery and a battery interface configured to electrically couple the battery to at least one component of the electrified vehicle.

A concrete mixer vehicle includes a chassis, a tractive assembly coupled to the chassis and configured to propel the concrete mixer vehicle, a mixing drum rotatably coupled to the chassis, and an electromagnetic device configured to convert electrical energy to mechanical energy to drive the tractive assembly. In a first configuration, a first battery module is removably coupled to the chassis and configured to provide the electrical energy to the electromagnetic device, and in a second configuration, the first battery module is removed from the chassis and replaced with a second battery module, the second battery module removably coupled to the chassis and configured to provide the electrical energy to the electromagnetic device.

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 chassis platform including: a frame having a front frame end, a rear frame end, a longitudinal frame axis, an upper frame surface, a bottom frame surface, a first longitudinal lateral frame surface and a second longitudinal lateral frame surface, wherein the upper frame surface is substantially flat; and two or more mechanical connection assemblies each coupled to one of the first and second longitudinal lateral surfaces, each of mechanical connection assemblies to couple a vehicle corner module (VCM) to the frame and to transfer mechanical loads between the frame and the VCM when the VCM is coupled to the frame.

A vehicle includes: a rotating electrical machine configured to drive the vehicle; a high-voltage power source configured to supply electricity for driving the rotating electrical machine; main and backup low-voltage power sources; a normal load configured to operate on the electricity supplied from the main low-voltage power source; a critical load configured to operate on the electricity supplied from the backup low-voltage power source; and a floor panel. The critical load includes an auxiliary load for controlling, braking, steering, or acquiring external information of the vehicle. A central tunnel extending in a central part of the vehicle in the vehicle width direction along the vehicle length direction is formed in the floor panel. The low-voltage power sources are placed right above the floor panel. One of them is placed to one side of the central tunnel in the vehicle width direction, and the other one the other side.

A multi-module battery pack includes a battery tray defining multiple battery tray compartments, battery modules each disposed within a corresponding one of the compartments, and a thermal barrier arranged in a predefined heat transfer path through the tray between an adjacent pair of the battery modules. The thermal barrier has a thickness of at least about 1 mm and a thermal conductivity of less than about 4 W/m-K, such that the thermal barrier blocks the heat transfer path to mitigate a thermal runaway event of one of the adjacent pair of battery modules. An electric powertrain system includes a rotary electric machine having phase leads and an output member, a driven load coupled to the output member, and the multi-module battery pack. A method includes providing the tray, identifying the heat transfer path, and arranging the thermal barrier in the heat transfer path.

Systems, methods, and a device which produces and stores electrical energy from primarily the forward movement of a vehicle is disclosed. This device has a variety of potential applications, such as use with a semitrailer and various types of electric vehicles. It also includes a number of features, such as functioning as a cryptocurrency mining rig that uses excess electricity generated, that add to its usefulness.

The exemplified systems and methods provide fixed and exchangeable energy storage and delivery system in an electrified vehicle architecture with multi-mode controls. The exchangeable energy storage are configured to be optional and ultra-portable. The integration of fixed and exchangeable energy storage provides a vehicle configuration that is further optimized for size, weight, and convenience.

A power supply assembly includes: a casing having a base and at least two side walls; and a set of battery modules. Each of the modules includes a battery having two opposing ends, and two opposing flanges covering the ends. The modules are installed on the base in a plurality of rows of modules arranged in line with one another. The rows are arranged such that the flanges are aligned edge to edge. The aligned flanges are joined to the base of the casing so as to form rigid cross members inside the casing.
