It becomes possible to monitor a driven state of each wheel in a wheelchair whose wheels are driven according to output information calculated based on input information. A left wheel controller and a right wheel controller are provided. The presence or absence of a drive abnormality of the left wheel is determined by the right wheel controller receiving first drive related information that is related to a drive of the left wheel and transmitted from the left wheel controller, and the presence or absence of a drive abnormality of the left wheel is determined by the left wheel controller receiving second drive related information that is related to a drive of the right wheel and transmitted from the right wheel controller.

A small electric vehicle includes: a body with a forward, backward, and a width direction; left and right driving wheels in the width direction of the body; free wheels, apart from the driving wheels, in the forward and backward direction; left and right motors to respectively transmit power to the left and right driving wheels; left and right rotation speed sensors detecting rotation speeds of the respective motors; an operation unit with an operation element; and a control unit controlling the motors according to an operation on the operation element, the control unit calculates target rotation speeds of the motors, based on a target vehicle speed provided by an operation position of the operation element, and on a target vehicle angular velocity provided by the operation position of the operation element and by the actual speed of the vehicle, and control the left and right motors such that actual rotation speeds of the motors follow the respective target rotation speeds.

A small electric vehicle includes: left and right motors connected so as to respectively transmit power to left and right driving wheels; left and right rotation speed sensors; an inclination sensor; a joystick-type operation element; and a control unit, wherein it is configured to calculate target rotation speeds of the left and right motors, based on a target vehicle speed provided by an inclination angle in consideration of the pitch angle and the roll angle detected through the inclination sensor and by an operation position of the operation element, and on a target vehicle angular velocity provided by the inclination angle, by the operation position of the operation element and by the actual speed of the vehicle, and control the left and right motors such that actual rotation speeds of the left and right motors follow the respective target rotation speeds.

A battery compartment, a battery compartment assembly and an electric scooter are provided. The battery compartment is used for an electric scooter, and includes a compartment body and a limiting flange. The electric scooter includes a frame with an opening, and the opening runs through the frame in an up-down direction. The compartment body is configured to penetrate through the opening, and the limiting flange is arranged to an outer side wall of the compartment body and configured to abut against the frame to prevent the compartment body from falling out of the opening downwards.

Techniques are disclosed for systems and methods associated with a micromobility transit vehicle battery connection and lock. In accordance with one or more embodiments, a micromobility transit vehicle is provided. The micromobility transit vehicle may include a frame, a battery configured to be received at least partially within the frame, and a battery lock within the frame. The frame may include a downtube having a recess disposed therein. The battery may be configured to be received within the downtube and the recess to establish a continuous surface comprising one or more outer surfaces of the downtube and one or more outer surfaces of the battery. The battery lock may be positioned within the recess and configured to engage the battery to lock the battery in place.

The invention is directed systems, methods, and devices for a modular charging station configured to be expanded or retracted to accommodate and charge a variable number of light electric personal mobility vehicles, and in particular electric two-wheeled, self-balancing, non-tandem light electric personal mobility vehicles. Additional embodiments include a novel vehicle adaptor configured to be coupled to a light electric personal mobility vehicle that is further in electrical communication with the vehicle's battery therewith, that can further be coupled with a receiving dock on a modular charging station that is configured to communicate with, and electrically charge the vehicle's battery from a power supply.

A method and system for providing a cooperative automotive mobile charging infrastructure are described. In one embodiment, a method for providing a cooperative automotive mobile charging infrastructure includes receiving a notification indicating an availability for providing mobile charging to electric personal transport devices. Each notification includes an identification of an electrified vehicle to provide the mobile charging and a location of the electrified vehicle. The method includes receiving a request for mobile charging from a user and determining a candidate electrified vehicle that is available to provide mobile charging to the user. The method also includes providing the location of the candidate electrified vehicle to the user to provide mobile charging at the location to an electric personal transport device associated with the user.

An electric powered vehicle may include a maximum speed limiting device. In the first mode, in a case where the distance is shorter than a first reference value, the maximum speed is limited to a value lower than the maximum speed applied when the distance is longer than the first reference value. In the second mode, in a case where the distance is shorter than a second reference value, the maximum speed is limited to a value lower than the maximum speed applied when the distance is longer than the second reference value. In a case where the distance changes from a value shorter than the first and second reference values to a value longer the first and second reference values, the maximum speed limiting device increases the maximum speed at an earlier timing in the second mode than in the first mode.

An exoskeleton system comprising: a power system that powers the exoskeleton system, the power system including one or more battery slots, and a modular battery set that includes one or more battery units that are modular such that any of the one or more battery units can be readily and quickly removed and coupled within any of the one or more battery slots to provide power to the exoskeleton system.

Provided is an electric scooter with a top-swappable battery. In some embodiments, the electric scooter a frame having an opening, and a removable deck assembly disposed in the opening, the removable deck assembly comprising a deck having an upper surface and a lower surface, and a battery pack attached to the lower surface of the deck.
