Methods and systems are provided for an electric vehicle powertrain. The vehicle system includes an electric distribution assembly with a junction box that is electrically coupled to a traction motor-generator and is designed to electrically coupled to, via separate circuits, a traction battery assembly and a hydrogen fuel cell assembly that is positioned behind a vehicle cab. In the system, the traction battery assembly is positioned vertically below the hydrogen fuel cell assembly.

Electric powertrain and method for operation of said powertrain

Methods and systems are provided for a winding reconfiguration assembly for an electric machine. The winding reconfiguration assembly includes a multi-position contactor device designed to switch stator windings in the electric machine between a first electric configuration in a first position and a second electric configuration in a second position. The winding reconfiguration assembly further includes an electromagnetic actuator configured switch the multi-position contactor device between the first position and the second position in response to a change in the polarity of a coil in the electromagnetic actuator.

Winding reconfiguration assembly and method for operation of said assembly

Methods and systems are provided for cooling a hydrogen fuel cell assembly. A vehicle system, in one example, includes a hydrogen fuel cell assembly electrically coupled to a traction motor, positioned behind a cab, and including a plurality of hydrogen storage tanks and hydrogen fuel cells. The vehicle system further includes a fuel cell cooling assembly including an inlet manifold in a deflector, where the deflector is fixedly coupled to and positioned vertically above the cab and designed to direct airflow to a fan array that is coupled to a fuel cell assembly heat exchanger, where the fan array is positioned behind inlet manifold and longitudinally offset therefrom.

Electric powertrain cooling assembly and cooling assembly operating method

Systems are provided for a cooling system for an electric vehicle. In one example, a system includes a plate arranged between separate circuit boards. The plate directly cools one of the circuit boards and block thermal communication between the circuit boards.

Systems for thermal management of a vehicle

An autonomous vehicle for passengers includes four steerable wheels where each steerable wheel is steered by a steering system having a set of two actuators. One actuator of each set of actuators is powered by a first power source while the other actuator of the set of powered by a second power source. Four controllers each control one actuator of each set of actuators and one actuator from another set of actuators.

The present disclosure is concerned with a stator for an electric machine comprising a plurality of stacked laminations each including inwardly facing slots defining inwardly facing teeth configured to receive prewound coils thereonto. Each slot including a generally triangular projection configured and sized as to be in proximity of the prewound coils.

Stator assembly with heat recovery for electric machines

A system and a method for managing a charging station allow charging a battery of a connected autonomous electric vehicle for carrying passengers in a controlled environment. A controller connected to the charging station determines and modulates a charging rate with which the charging station charges the battery based on a duration between a start of charging the vehicle and a forecasted time of start of duty mode of the vehicle. The duration is determined by the controller based on a forecasted passenger load as a function of time.

System and method for modulating a charging rate for charging a battery of a vehicle as a function of an expected passenger load

An electric machine is described herein. The electric machine includes a casing, a stator, a rotor generally coaxial with the stator, an enclosed cooling assembly circulating a first cooling fluid within the casing, and an open cooling assembly through which a second cooling assembly can flow; the open cooling assembly cooling both the stator and the first cooling fluid.

Electric machine provided with an enclosed cooling assembly paired to an open cooling assembly

An embodiment of a liquid cooled electric machine is provided with an enclosed stator and includes a cooling assembly so configured as to allow cooling liquid to flow in the coil receiving slots of the enclosed stator to thereby cool the coils positioned therein.

Liquid cooled electric machine with enclosed stator

External rotor electric machine with SMC blocks interposed between permanent magnets. The machine has an internal stator and an external cylindrical rotor. Permanent magnets and SMC blocks are mounted on the inner surface of the rotor.

External rotor electric machine with SMC blocks interposed between permanent magnets

The external rotor for an electric machine includes a cylindrically shaped receptacle having a peripheral wall and a magnet-receiving assembly including segments assembled to the inner surface of the peripheral wall so as to define a cylindrically shaped stack. The segments are shaped so as to yield magnet-receiving portions in the ring-shaped stack, and permanent magnets are secured to the magnet-receiving portion of the magnet receiving assembly.

The insertion of electrically insulating paper from a continuous roll into slots of a stator created by outwardly projecting teeth is described herein. The insertion of the insulating paper is done by the insertion of prewound coils in the stator slots. The electrically insulating paper is not cut prior to its insertion in the slots, thereby completely covering the outer surface of the stator. The insertion systems and methods described herein are also optionally concerned with the insertion of interphase insulation paper between the different coils inserted in the stator slots and with the insertion of slot closing wedges.

Insertion system and method to insert insulators and coils in the slots of the stator of an electric machine

A liquid cooling arrangement for electric machines uses a continuous cooling tube associated with a heat storing element. The cooling tube has a serpentine configuration and the heat storing element includes longitudinal slots starting from both longitudinal ends of the heat storing element. Accordingly, it is possible to slightly deform the heat storing element to properly position it into the internal stator of an electric machine. An internal biasing assembly may be used to force the external surface of the heat storing element to the internal surface of the stator.
