A power module of an electric assisted bicycle is disclosed and includes a pedal shaft, a gear-plate-output shaft, a reducer-output shaft and a motor-output shaft. The pedal shaft is arranged along an axial direction. The gear-plate-output shaft includes a first section and a second section arranged in the axial direction. The first section is concentrically sleeved on the pedal shaft through a first one-way bearing along a radial direction. When the pedal shaft is forced to rotate, the gear-plate-output shaft is driven through the first one-way bearing. The reducer-output shaft is concentrically sleeved on an outer surface of the second section through a second one-way bearing along the radial direction. The motor-output shaft is concentrically sleeved on the reducer-output shaft along the radial direction. When the motor-output shaft drives the reducer-output shaft to rotate, the gear-plate-output shaft is driven by the reducer-output shaft through the second one-way bearing.

A motor unit for use in an electric bicycle includes a motor, a switching element, a board, and a case. The switching element has the motor driven. The board has a principal surface and a reverse surface. The principal surface includes a mounting surface to mount the switching element thereon. The reverse surface faces opposite from the principal surface. The case houses the board therein. The board further has a through hole provided to penetrate through the board from the mounting surface through the reverse surface and a sheet of metal foil covering an inner peripheral surface of the through hole at least partially. The switching element is thermally connected to the sheet of metal foil. A part, located opposite from the switching element with respect to the board, of the case is thermally connected to the sheet of metal foil.

A system for charging electrical micromobility vehicles includes a post (20); a socket (30) located in the post (20); and a plug (40) to be mounted on the vehicle. The socket (30) has a longitudinal opening (34) arranged vertically on the post (20). The height (H) of the opening (34) of the socket (30) is larger than the height (h) of the plug (40). The socket (30) has a socket first and second contact means (31, 32). The plug (40) has a plug first and second contact means (41, 42) arranged so that when the plug (40) is inserted into the socket (30) at any position along the height (H) of the opening (34), the socket first and second contact means (31, 32) form an electrical connection with the corresponding plug first and second contact means (41, 42).

A battery device of an electric bicycle includes a battery, a battery mount which allows attachment/detachment of the battery, a stepped portion, and a restriction release in a first end of the battery, and an engaging portion and a second movement restrictor in a first support of the battery mount. The engaging portion is restricted in its movement, by the second movement restrictor, from an engaged position where it is engaged by the stepped portion to a disengaged position where it is not engaged by the stepped portion. When the battery is to be removed, from the battery mount, the restriction by the second movement restrictor is removed, the restriction release is used to move the engaging portion from the engaged position to the disengaged position, and then the battery is pulled in a removal direction, to remove the battery from the battery mount.

An electrical device for a system of a human-powered vehicle comprises a controller. The controller is configured to selectively act, based on reference information relating to the system, as each of a master controller and a slave controller. The master controller is configured to transmit a first control signal to a different slave controller of a different electrical device of the system. The different slave controller is configured to be operated in response to the first control signal. The slave controller is configured to be operated in response to a second control signal transmitted from a different master controller of a different electrical device of the system.

A multifunction electric vehicle charging platform is provided. The platform includes a housing and at least one display unit placed in the housing. The platform further includes a content management unit configured to control receiving content and display the content on the at least one display unit. The platform includes a charging unit configured to be connected to at least one light electric vehicle (LEV) and to provide power to the at least one LEV. The platform includes at least one sensor attached to the housing and configured to collect data associated with the at least one LEV. The platform further includes a communication unit configured to communicate with a backend system.

The invention relates to a device for energy recovery in bicycles with a mid-mounted motor drive unit and at least one rear wheel, comprising a first component that is connected to an element of the rear wheel hub or the rear wheel, such that a rotation of the rear wheel is transmitted to the first component, regardless of the direction of rotation, an energy-transmission device interacting with the first component, a recuperation element that interacts with the energy-transmission device, and a generator that interacts with the recuperation element to recover the rotational energy of the rotational movement of the rear wheel.

A system for compensating acceleration of electrical motorbike includes a throttle unit and an electro-mechanic assembly. After the electrical motorbike starts, the throttle unit receives external operation from a rider for generating a series of original throttle signal. An acceleration compensating module calculates a throttle variation rate based on the original throttle signal and variation of a throttle operation magnitude, and calculates a throttle compensating value based on the throttle variation rate when the throttle variation rate is larger than or equal to a correction threshold. A throttle compensating module receives and sums the original throttle signal and the throttle compensating value up for generating a new throttle signal. A torque controller generates a corresponding torque command based on the new throttle signal, and outputs the torque command to the electro-mechanic assembly for operation.

A solar powered electric motorized scooter is provided for use with a battery, the solar powered electric motorized scooter comprising a base, a flexible foot pad which has a margin, the margin attached to the base, a plurality of flexible solar cells mounted on the base, an electric motor which is in electrical communication with the flexible solar cells, a front wheel, a back wheel, the wheels rotatably disposed on the base and in motive communication with the motor, a steering tube rotatably mounted to the base and attached to a bracket that retains the axle of the front wheel and a handlebar, which terminates the steering tube, wherein the flexible foot pad is configured to flatten under the pressure of a rider and to curve upward when not under pressure of the rider.

A vehicle with a Geo-Fenced Ride Control System including: one or more battery modules including one or more battery cells; one or more processors operably connected to the one or more battery cells to control vehicle performance; and a Global Positioning System (GPS) or cellular network receiver configured to determine location of the vehicle; wherein the one or more processors communicates with a remote sever to determine a plurality of available vehicle performance settings for the vehicle based on the location of the vehicle. The vehicle further includes a user input interface configured to receive user input including selection of the vehicle performance setting form the plurality of available vehicle performance settings based on the geographic location of the vehicle.
