Embodiments include a multi-level electric vehicle supply equipment (EVSE) unit. The multi-level EVSE unit can include a Level 2 charge handle, a receptacle configured to receive the Level 2 charge handle, and a Level 1 outlet including one or more plug outlets configured to receive one or more corresponding Level 1 plugs. The Level 2 charge handle can be permanently attached to the multi-level EVSE unit via a cable. The Level 1 outlet can temporarily receive the one or more corresponding Level 1 plugs. A first power meter associated with the Level 2 charge handle can meter power delivered via the Level 2 charge handle. A second power meter associated with the Level 1 outlet can meter power delivered via the Level 1 outlet. A charging logic and relay section can intelligently allocate power between the Level 2 handle and the Level 1 outlet according to charging rules.

Electromechanical systems using magnetic fields to induce eddy currents and generate lift are described. Magnet configurations which can be employed in the systems are illustrated. The magnet configuration can be used to generate lift and/or thrust. Arrangements of hover engines, which can employ the magnet configurations, are described. Further, vehicles, which employ the hover engines and associated hover engines are described.

A method of driving a manned vehicle includes following steps of: acquiring correspondingly initial weight values of a plurality of weight sensors, each weight sensor is corresponding to a direction; acquiring correspondingly weight measurement values by the weight sensors; calculating correspondingly a weight ratio of each weight sensor according to the initial weight value and the weight measurement value of each weight sensor; producing a control command according to the direction corresponding to the weight sensor when the weight ratio of any one of the weight sensors is greater than a first threshold value; and driving the manned vehicle to move according to the control command. Accordingly, it is to effectively reduce the size and weight of the manned vehicle and reduce the difficulty of controlling the manned vehicle by intuitively controlling moving directions of the manned vehicle according to variations of the center of gravity of a user.

An embodiment apparatus for wirelessly transmitting and receiving power for a personal mobility device having a replaceable module includes a power transmitter; a processor and a non-transitory computer-readable storage medium having recorded thereon one or more programs executable by the processor, wherein the one or more programs include instructions for implementing an identification unit configured to identify an upper module coupled to a base frame, and a power setting unit configured to set a maximum power to be wirelessly transmitted to the identified upper module, wherein the maximum power is set depending on the upper module, wherein the power transmitter is configured to wirelessly transmitt power to the identified upper module within the set maximum power.

A gear drive balancing scooter is provided that has a left side, a right side, and a center section located between the left and right side. The center section is coupled to the right and left sides through a gear. As the left side moves with respect to the center section, the right side moves in an opposite direction with respect to the center section. Both sides have a respective wheel motor assembly that is used to balance the scooter. To steer the scooter, the user angles one side differently than the other side. The angle of each side determines the rate and direction that each wheel motor assembly rotates. An optional staff extends upwardly from the center section to provide stability.

A battery powered ride-on vehicle is provided that has vehicle body, a plurality of wheels, a battery dock, a battery having battery terminals that mate with battery dock terminals, an accelerator switch and an accelerator switch controller, a power line to allow current to flow between the battery dock and the accelerator switch controller, a plurality of electrical components, an electronics controller in electrical communication with the accelerator switch controller and the electrical components, a power line connecting the electronics controller with the accelerator switch controller to allow current to flow between the accelerator switch controller and the electronics controller, a timer that calculates the time between actuations of the accelerator switch, and when the time between actuations of the accelerator switch is greater than a timer threshold the accelerator switch controller prevents a release of current to the electronics controller until the accelerator switch is actuated again.

An electric skateboard includes a motor, a controller, and a pressure sensor located in a footboard. When a user of the skateboard places a foot on the pressure sensor, the controller measures an actual or estimated speed of the skateboard, and outputs a control signal to the motor to maintain the measured speed. When a user removes his foot from the pressure sensor, the controller sends a control signal to stop the motor.

A method of operating an electric skateboard includes manually moving the electric skateboard forward without engaging an electric motor, then engaging a pressure sensor on the electric skateboard to output a pressure signal to a controller on the electric skateboard. The controller then generates a control signal to the electric motor corresponding to a first cruising torque. The method further includes engaging the pressure sensor on the electric skateboard a second time, to output a second pressure signal to the controller, which in turn generates a second control signal corresponding to a second cruising torque.

A battery-powered vehicle is provided having dual charging capabilities. The vehicle has a body, a plurality of wheels supporting the body, a motor connected to at least one of the plurality of wheels, a battery port having a battery dock and battery dock terminals, a remote charging dock on an exterior of the vehicle body, the remote charging dock having remote charging terminals, a charger having a charger plug and associated charger terminals, and a removable and rechargeable battery having battery terminals. The battery is configured to be positioned in the battery port for charging in the battery port and to have the battery terminals electrically and mechanically mate with the battery dock terminals. The battery is also configured to be removed from the battery port and to have the battery terminals electrically and mechanically mate with the charger terminals for charging outside the battery port.

A toddler mobility system and apparatus comprising a chassis, two casters attached to the front of the chassis, two wheels attached to a rear of the chassis, a first motor operably connected to one of the at least two wheels, a second motor operably connected to another of the at least two wheels, a battery configured to supply power to the motors, a body affixed to the chassis and covering the chassis, the body further comprising an integrated seat, an integrated backrest, a control system wherein the control system further comprises a microcontroller operably connected to a joystick, and a motor controller that receives control input from the microcontroller and adjusts power to the first motor and the second motor independently, wherein the toddler mobility system is configured for users weighing 50 pounds or less.
