The invention relates to 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.

Electric vehicles and charging stations

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.

Charging stations for electric vehicles

The invention provides for a high occupancy or heavy-duty vehicle with a battery propulsion power source, which may include lithium titanate batteries. The vehicle may be all-battery or may be a hybrid, and may have a composite body. The vehicle battery system may be housed within the floor of the vehicle and may have different groupings and arrangements.

Low-floor electric vehicle

An operable ramp is moveable between a stowed position and a deployed position to provide a sloped transition between upper and lower surfaces of an architectural setting. The operable ramp includes a ramp panel and a drive assembly coupled to a first end of the ramp panel so that the drive assembly reciprocates the operable ramp between the stowed position and the deployed position. The drive assembly defines a maximum elevation of the first end of the ramp panel when the operable ramp is in the deployed position and also defines a minimum elevation of the first end of the ramp panel when the operable ramp is in the stowed position. The maximum elevation is selectively adjustable relative to the minimum elevation.

Operable ramp

A method is disclosed for deploying a ramp assembly. The ramp assembly includes a ramp portion rotatable between a stowed position and a deployed position. The ramp assembly further includes a panel rotatable about a first end, wherein the ramp portion supportingly engages a second end of the panel to elevate the second end of the panel as the ramp portion moves toward the deployed position. The method includes the step of rotating the ramp portion until the ramp portion contacts an alighting surface. The method further includes the step of rotating the ramp portion until one of a first condition and second condition occurs. The first condition is that the ramp portion has reached a maximum slope. The second condition is that the second end of the panel has reached a predetermined elevation.

Fold out ramp

An operable ramp is moveable between a stowed position and a deployed position to provide a sloped transition surface between upper and lower surfaces of an architectural setting. The operable ramp includes a housing disposed on the lower surface of the architectural setting and having a selectively adjustable height. A first ramp panel has a support element extending from a first end. The operable ramp also includes a drive assembly located within the housing. The drive assembly includes an endless loop coupled to an end of the support element to move the operable ramp between the stowed position and the deployed position. The endless loop has a linear portion located between first and second arcuate portions. The endless loop raises the end of the support element to deploy first ramp panel. The distance between the first and second arcuate portions is selectively adjustable.

An operable ramp is moveable between a raised position, in which the ramp forms a pair of steps, and a lowered position, in which the operable ramp provides an inclined surface. The operable ramp includes a first panel rotatably coupled about a first axis that moves back and forth when the operable ramp moves between the lowered position and the raised position. A link is rotatably coupled to the first panel about a second axis and is itself rotatable about a fixed third axis. A second panel is rotatably coupled to the link between the second axis and the third axis, and a third panel is rotatably coupled to the second panel about a fourth axis. When the ramp moves between the raised and lowered positions, the fourth axis rotates about a fixed fifth axis. A linkage selectively rotates the first panel about the first axis.

A simulation device imparts a force corresponding to a simulated event on a user. The simulation device includes a motion base mounted to a moveable surface and a capsule mounted to the motion base. The user is positioned within the capsule during the simulated event, and the motion base is configured to move the capsule relative to the moveable surface. The simulation device further includes a sensor that senses movement of the moveable surface. A controller is operably coupled to both the sensor and the motion base. The controller receives a signal from the sensor and controls the motion base to move the capsule according to the simulated event and the signal received from the sensor.

Simulation device with motion stabilization

Charging of electric vehicles

A motion simulation device includes a base and a first arm rotatably coupled to the base about a first axis. The device further includes a drive element rotatably coupled to the base about a second axis. A second arm is rotatably coupled to the drive element about a third axis. A first end of the first arm is rotatably coupled to a capsule, and a first end of the second arm is also rotatably coupled to the capsule. The first arm and drive element are selectively rotatable to control the pitch and the elevation of the capsule.

Motion platform for a simulation device

A ramp assembly for providing a transition surface between a vehicle floor and an alighting surface is disclosed. The ramp assembly includes a ramp portion that is rotatable between a stowed position and a deployed position. A target operably associated with the ramp portion so that the target reciprocates along a predetermined path when the ramp portion reciprocates between the stowed position and the deployed position. A sensor fitting maintains a fixed orientation relative to a horizontal plane. A sensor is mounted to the sensor fitting such that the sensor senses the target when the ramp portion is in a predetermined position.
