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 transport vehicle configured to run on electricity generated by a fuel cell includes: a body having a cargo space for freight; a chassis frame located below the body and supporting the body; and a tank unit including a plurality of tanks that stores fuel gas to be used for power generation by the fuel cell and a connecting portion connecting the tanks, the tank unit being located between the cargo space and the chassis frame.

A power management system is disclosed for managing power in a vehicle. The system may include a power distribution unit (PDU) communicably coupled to a power controller unit located in the vehicle. The power controller unit comprises a microcontroller configured to: receive, from the PDU, a temperature value that indicates a temperature of the PDU, one or more voltage values from the one or more voltage sensors, or one or more current values from the one or more current sensors, perform a determination that the temperature value, the one or more voltage values, or the one or more current values are below one or more of their respective pre-determined threshold values, and send, after the determination, a health status message to a computer located in the vehicle, where the health status message indicates that the PDU is operating in a safe operating condition.

A sensor is mounted to or embedded in a wheel hub. The sensor node includes a power source and a sensing device that detects and monitors at least one parameter associated with the wheel hub. The sensor node also includes a communication module that communicates via wireless communication signals and a processing device in communication with the sensing device and the communication module. The processing device collects data from the sensing devices, processes the data, and based on that processing, communicates information relating to the wheel hub to a remote server or network. A mesh network of multiple sensor nodes can be applied to multiple different wheel hubs on a vehicle and communicate with a central processing device. The processing device can thus monitor performance and/or operation of each wheel hub.

An automated mechanical transmission for a vehicle includes a main gearbox assembly comprising a main shaft and being adapted to be shiftable between at least one engaged state and a neutral state; a split gearbox assembly comprising an input shaft and being adapted to be shiftable between a first engaged state, a second engaged state and a neutral state; a countershaft; a crawler gearbox assembly comprising a crawler gear engagement member which is adapted to selectively engage and disengage a crawler gear defining a torque path from the input shaft to the main gearbox assembly via the countershaft; a gearbox brake; and transmission control unit. The transmission is configured to be settable in an AMT neutral state defined by the main gearbox assembly being in the neutral state. When the transmission control unit obtains a request to engage the crawler gear from the AMT neutral state, the transmission control unit is configured to apply the gearbox brake so that a rotational speed of the countershaft is reduced to a first predetermined rotational speed which is higher than a zero rotational speed; and when the first predetermined rotational speed is reached, release the gearbox brake, set the split gearbox assembly to the neutral state and engage the crawler gear by the crawler gear engagement member.

A method of oil pre-conditioning for an electric powertrain for a vehicle configured to provide electric propulsion of the vehicle, said electric powertrain comprising the first electric motor being linked to the first gear module, a secondary shaft being linked to the second gear module, the second electric motor being linked to the third gear module through a motor shaft, the differential being shared by both electric motors,

The electric powertrain is surrounded by an oil. The method includes the steps of selecting an oil pre-conditioning configuration wherein the secondary shaft does not rotate and at least one of the first electric motor or the second electric motor rotates while the other is in driving mode leading to the heating of the oil to reach a threshold temperature and applying the selected oil pre-conditioning configuration.

Methods and systems for an electric drive assembly are provided herein. In one example, an electric drive system is provided that includes two multi-motor drive units with associated planetary gear reductions that have asymmetric gear ratios. The planetary gear reduction in each drive unit includes a ring gear and a sun gear that are rotationally coupled to a pair of motors and a carrier rotationally coupled to an output gear that interfaces with a gear reduction of an axle assembly.

A fuel cell assembly is mounted on a vehicle via a mounting portion. The fuel cell assembly includes a first fuel cell unit, a first frame portion on which the first fuel cell unit is mounted and fixed, a second fuel cell unit, a second frame portion on which the second fuel cell unit is mounted and fixed, and a connecting portion that connects the first frame portion and the second frame portion such that the second fuel cell unit is located above the first fuel cell unit.

A vehicle thermal management system is disclosed comprising a first and a second coolant circuit each comprising a coolant pump. The first coolant circuit comprises a coolant duct configured to conduct coolant flow through a portion of the first coolant circuit, and an expansion tank connected to the coolant duct. The system further comprises a first connecting conduit connecting the second coolant circuit to the coolant duct, and valve controllable between a first state in which the valve hinders flow of fluid through the first connecting conduit, and a second state in which the valve allows flow of fluid through the first connecting conduit. The present disclosure further relates to a vehicle comprising a vehicle thermal management system.

An electric truck ladder system comprises a support frame mounted beneath a vehicle in turn supporting a retractable ladder in hydraulic communication with a switch. The switch permits a user to deploy and/or retract the ladder. The system provides for an adjustable height, adjustable actuator stroke, a switch with wireless remote actuation and/or a door switch which actuates the ladder upon the opening or closing of a vehicle door.
