A direct current traction motor control system includes plural motors of with each of the motors configured to be coupled with a different axle of a vehicle and to rotate the axle to propel the vehicle. The motors are coupled with a DC bus and configured to receive DC via the DC bus to power the motors. The system also includes plural switch assemblies with each of the switch assemblies having an H-bridge circuit coupled with a different motor of the motors to control rotation of the motor. The system includes a controller configured to communicate control signals to the switch assemblies to individually control the H-bridge circuits to control one or more of torques output by the motors or rotation directions of the motors.

Vehicle depots or yards adapted to charge multiple electric vehicles include multiple charging electrodes to simultaneously direct power to multiple electric vehicles. The charging electrodes may direct power to the electric vehicles from an utility grid or from a secondary power source.

A low-floor electric bus includes a plurality of battery packs mounted under the floor of such that the floor inside the bus between a front axle and a rear axle of the bus is substantially flat. Each battery pack may include an enclosure and multiple battery modules positioned within the enclosure. And, each battery module may include a plurality of battery cells electrically connected together.

Provided is a cooling module for a vehicle, and more particularly, a cooling module placed on a side of the vehicle with three-row mounting parts, in which components are mounted, to maximize cooling efficiency and space utilization inside the vehicle.

This disclosure provides systems and methods for charging a vehicle. A vehicle and charging station can be designed such that an electric or hybrid vehicle can operate in a fashion similar to a conventional vehicle by being opportunity charged throughout a known route.

The present invention relates to new energy vehicle field, and more particularly to a vehicle-mounted photovoltaic power generation device for large vehicles. at present, large-scale new energy vehicles such as buses, passenger carriage, trucks, and touring car, use photovoltaic power generation technology with fixed brackets to increase their cruising range, however, due to its low power generation and untraceable defects, it is a technical problem that needs to be solved urgently in the field of new energy vehicles. the invention provides a vehicle-mounted fixed type and tracking type integrated technology is not only enhances wind resistance, but also improves power generation efficiency, and builds a 2-dimensional tracking photovoltaic power generation device without photoelectric sensors, compared with products that cannot track, the solar power generation of the present invention is increased by more than 40% on average.

A scalable tractive power system for vehicles (car, truck, bus, semi-trailer), integrated with all-wheel steering system which leverage synergies between plurality of differently designed electric traction-motors and all-wheel electric steering-motors is configured with plurality of sensors to virtually eliminate wheel-dragging and EPS, as part of virtually 100% dynamic efficiency. A fully automated electronic clutch-system attached to selected electric traction motors is configured to carry out above 90% traction efficiency by coupling to wheels selected electric traction-motors in their high efficiency range of operation, and de-coupling and replacing electric traction-motors with another electric traction-motors while the vehicle is changing speed or when the vehicle requires higher or lower tractive-power, from forward-motion start to top-rated speed of the vehicle. A holistic controller is configured with multi-objective optimization design (MOOD) procedures computing complex variable values and parameters, finding the required trade-off among design objectives, and improving the pertinence of solutions, while complying with NHTSA's ‘fail operational systems’ for steer-by-wire.

A charging station for charging an electric bus is provided which includes a power rail extending along an axial direction above a plurality of electric buses parked in a parking space, a pantograph disposed in a lower portion of the power rail to be movable horizontally along the axial direction and expandable in a gravitational direction from above the electric bus to electrically contact the electric bus, and a controller configured to calculate a charging sequence of the plurality of electric buses based on position information of the plurality of electric buses, wherein the controller is configured to control horizontal movement of the pantograph and electrical contact with the electric bus according to the charging sequence so as to supply the power applied from an external power network through the power rail to the electric bus through the pantograph.

A charging station for an electric vehicle includes a passive alignment mechanism that includes a longitudinal translation stage that allows motion in a longitudinal direction, a charging plug connected to the passive alignment mechanism, and a releasable connector. The releasable connector resists motion of the longitudinal translation stage in a connected position when a magnitude of an external force applied in the longitudinal direction is below a threshold. The releasable connector moves from the connected position to a released position to allow motion of the longitudinal translation stage when the magnitude of the external force applied in the longitudinal direction is above the threshold.

In general, this disclosure relates to a system and method of control for driveline actuators (DLAs) in the powertrain of an electric vehicle to perform shifting between two-wheel drive (2WD) and four-wheel drive (4WD) configurations. Sequential and overlapping shift process is used. The first disconnect is instructed by a vehicle control system to begin its shift, which takes approximately 100 milliseconds to complete. A short period of time after the first disconnect is instructed to begin its shift, but before it has completed the shift, the second disconnect is instructed to begin.
