Patent attributes
Electric vehicles include adjustable battery positions and/or adjustable track widths for controlling vehicle stability. In some examples, an electric vehicle comprises a positioning mechanism configured to move the battery pack relative to the support structure (e.g., operable as the vehicle's frame) to change the vehicle's COG. The battery pack can be moved in response to other vehicle operations, e.g., COG changes caused by adding/moving loads, changes to the route grade, and the like. The battery pack can be slidably coupled to the support structure. In some examples, an electric vehicle comprises a track adjustment mechanism configured to move the vehicle's wheel axle relative to the support structure, along the wheel axle center axis, thereby changing the track width. The wheel axle can be coupled to a hub motor. In some examples, the battery is moved, and/or the track width is changed during the vehicle's operation.
