In one embodiment, a micromobility transit vehicle includes a frame including a downtube having a recess, a battery configured to be received within the recess of the downtube such that an external surface is formed by the outer surfaces of the downtube and the battery, a power connector within the recess and configured to be engaged with the battery to establish an electrical connection between the power connector and the battery, and a spring assembly coupled to the power connector and configured to allow the power connector to move with the battery. The power connector includes one or more alignment pins configured to align the power connector with the battery when the battery is being received within the recess. The spring assembly biases the power connector toward a direction from which the recess is configured to receive the battery.

A method of operating a personal transporter includes mounting the personal transporter. A torque stick apparatus having a rotating wheel is provided. The wheel of the torque stick apparatus is positioned against a drive surface to drive the personal transporter across a transport surface.

A powered skateboard having a powered wheel. The powered wheel formed of a motor within tire of the wheel. The powered wheel fixed to a truck of the powered skateboard. The powered skateboard including at least one onboard battery to provide electrical power to the powered wheel.

A connecting structure which reduces a vibration effect of a power system on a vehicle body comprises a power system bracket, one end of the power system bracket being connected to a power system, another end being connected to a suspension, one end of the suspension being connected to a frame or a load-bearing vehicle body, another end being connected to an axle or wheels, the suspension being capable of attenuating and isolating high frequency vibrations produced by the power system. The power system is not directly connected to the vehicle body which is above shock absorbers, but rather connected to a suspension frame which is below the shock absorbers, extending the path whereby power system high frequency vibration energy is transferred to the vehicle body, so that the high frequency vibrations of the power system are effectively attenuated and isolated, and the vibrations of the vehicle body are reduced.

The four wheel vehicle uses an electric motor (142) for driving the vehicle and a battery unit (160) for supplying electric power to the electric motor. The lower chassis (5) of the vehicle includes a pair of front side frames (10) extending linearly in a fore and aft direction with an upward slant and a progressively increasing lateral mutual spacing from a front part thereof to a rear part thereof, a pair of rear side frames (12) connected to rear ends of the respective front side frames, and extending linearly in a fore and aft direction with an upward slant from a front part thereof to a rear part thereof in continuation of the corresponding front side frames in a mutually parallel relationship, and a plurality of cross members (14, 16, 18, 20, 22) connecting the side frames to each other.

An electric three wheeled vehicle includes a vehicle chassis supporting a vehicle operator seat or saddle. The vehicle chassis defines a storage region beneath the vehicle operator seat or saddle. One or more energy storage devices for powering one or more electric motors of the vehicle are located within the storage region and are supported by the chassis. The storage region and/or the energy storage device(s) each form an elongate three-dimensional volume having a long axis that is parallel to a longitudinal axis of the vehicle. A vehicle operator, when seated upon the seat or saddle, sits astride the one or more energy storage devices. A handlebar steering assembly is operatively coupled to a pair of front wheels to provide steering. The vehicle includes a single rear wheel.

In a rear structure for an electric vehicle including, at the rear of the vehicle body, an article storage unit supported on a rear frame, and a first lid configured to cover the article storage unit from above, the electric vehicle includes sub batteries serving as a drive source thereof, the sub batteries are stored in a battery storage unit disposed below the article storage unit, the article storage unit and the battery storage unit include an upper opening and a lower opening, respectively, which are open to the rear side of the vehicle, and a second lid configured to cover the upper opening and the lower opening is formed as a member different from the first lid. Such a rear structure for a vehicle is easy to use, and allows many articles be loaded on the article storage unit and be stored therein.

A powered skateboard having a powered wheel. The powered wheel formed of a motor within tire of the wheel. The powered wheel fixed to a truck of the powered skateboard. The powered skateboard including at least one onboard battery to provide electrical power to the powered wheel.

A dual motor powered compact drive comprises two electrical motors powering the planetary gear mechanism. The dual drive can provide variable speed and torque. A single electric motor operated braking system with a screw-driven wedged brake pads is described using a compact test set-up. The system comprises at least one motor and a screw shaft connected to transmit the power to a sliding plunger, and braking pads located on a braking disc, and a force sensor applied to measure the braking force, and a device to measure the parameters of the braking motor and the parameters are used as the inputs to establish a control strategy. Systems and methods for monitoring a battery pack including multiple cells are provided. The battery management system further comprises a control strategy for implementing a balancing algorithm. A balancing strategy comprises a determination of battery cells to be balanced, and a calculated balancing current.

System, methods, and other embodiments described herein relate to a low-profile vehicle. In one embodiment, the low-profile vehicle includes a vehicle body having a profile that is substantially continuous around an outer perimeter of the vehicle. The profile is comprised of a fin extending outward from a lower edge of the vehicle body and meeting a ramp of the vehicle body at a concave curve. The ramp continues from the concave curve into a convex curve where the ramp transitions into a top surface of the vehicle body. The profile has an exaggerated s-shape. The low-profile vehicle includes a hatch disposed within the top surface. The vehicle includes a passenger compartment disposed within the vehicle body and accessible through the hatch. The passenger compartment is shaped to provide for a passenger to occupy the vehicle in a substantially lying down position.
