The present invention is an electronic gear-shifting device of an electric motorcycle for simulating gear shifting power output, including an electronic shift unit, an electronic clutch unit and a throttle position sensor, and correspondingly outputting a shift signal, a clutch signal and a throttle position signal according to the operation of the rider. A vehicle controller receives the shift signal, the clutch signal and the throttle position signal to determine a target gear position of the electric motorcycle. The vehicle controller looks up a motor torque command according to the target gear position table and outputs the motor torque command to a motor controller, so that the motor controller controls an electric motor of electric motorcycle. Therefore, the electric motorcycle simulates the power performance of a general motorcycle without adding a physical clutch, a gearbox and other shifting mechanisms.

An assembling method of an electric vehicle comprises the steps of: assembling a vehicle body including a frame, wheels and an electric motor; conducting a vehicle body test including confirmation of a state of driving power transmission from the electric motor to the wheels by connecting an electric power supply unit installed in a vehicle body test place to the electric motor of the vehicle body and supplying electric power from the electric power supply unit to the electric motor; detaching the electric power supply unit from the electric motor and transporting the vehicle body which has passed the vehicle body test from the vehicle body test place to a mounting place, in a state in which a battery is not mounted to the vehicle body; and mounting the battery to the transported vehicle body in the mounting place.

An electric vehicle charging system in described that includes an electrical energy source that includes a base with a plurality of electrical signal connectors to receive a first electrical signal, a second electrical signal and a ground signal, an adapter having a plurality of outlet connectors configured to electrically connect to at least some of the plurality of electrical signal connectors, wherein the adapter can be placed in a plurality of positions on the base to correctly orient the base to any of plurality of outlet connector orientations, and a locking ring adapted to engage the base to removable fix the adapter to the base in one of the four positions. The system can include a thermistor assembly to sense thermal energy in the source and if thermal energy exceeds a threshold to output a signal. The system can include a charging cord for an electric vehicle having a proper orientation when engaging the source, wherein the adapter is in a correct orientation with the base being in the proper orientation when connected to the socket-outlet.

An electric vehicle includes front and rear wheels, a battery, an electric motor that drives at least one of the front and rear wheels, an accelerator, and a mode shift operator that is operated by a user in order to switch drive modes. The electric vehicle includes a driving force characteristics setter that sets, for each of the plurality of drive modes, driving force characteristics which are characteristics of an accelerator opening degree and a target motor driving force for the rotational speed of the electric motor. The electric vehicle further includes a controller which shifts up, according to an operation of the mode shift operator, the drive mode from a first drive mode to a second drive mode and which controls the target motor driving force according to the driving force characteristics. When a shift-down prohibition condition is met, the controller prohibits a shift down from the second drive mode to the first drive mode.

An auxiliary force control system and a method for a power-assisted bicycle are disclosed. The system has a sensing device, a mobile computing device, a first controller, and a second controller. The sensing device receives a riding torque and a riding speed. The mobile computing device generates a tuning factor via a first and a second ANN model. Personal data and historical riding data are input data of the first ANN model. Predicted grade outputted by the first ANN model, the personal data, and environment data are input data of the second ANN model. The first controller generates a final factor according to the tuning factor, a mode factor, and a gap-range factor. The second controller outputs a motor driver current according to a parameter of target output of the motor, which is generated based on the final factor, to the motor to drive the motor.

A bicycle battery device includes a bicycle frame tube such as a down tube. A battery is insertable in the longitudinal direction of the bicycle frame tube through a battery opening. An adjustment element is arranged between the battery and an inner contour of the bicycle frame tube to simplify the adjustment.

A rechargeable battery kiosk can dynamically alter a charging rate of one or more rechargeable batteries housed within the rechargeable battery kiosk to increase a probability that the rechargeable battery kiosk has an ample supply of fully charged, or mostly fully charged, rechargeable batteries based on an anticipated usage data for the rechargeable battery kiosk.

A motorcycle includes an electric motor having an output shaft defining a motor axis, a rear wheel drivably coupled to the electric motor to propel the motorcycle, a swingarm rotatably supporting the rear wheel, and a frame. The frame includes a main frame member supporting the electric motor and the swingarm. A case of the electric motor is a stressed member of the frame between the main frame member and the swingarm. The swingarm is coupled to the case of the electric motor to define a swingarm pivot axis that is co-axial with the motor axis.

The system (1) for piloting an electric motor in electric motorcycles or the like is operatively connectable to a control inverter (I) of an electric motor (E) of an electric motorcycle (M) and to a control device (C) of the acceleration of the electric motorcycle (M) and comprises dynamic generation means (10) of a piloting signal (T.sub.OUT) of the inverter (I) according to a control signal (G) coming from the control device (C) and to at least a maximum deliverable/absorbable current value (I.sub.MAX, RI.sub.MAX) by an electric battery (B) of the electric motorcycle (M).
