Abstract: A removable module and a method for operating the removable module. The removable module has a multipurpose connector that connect the removable module to a motor when the removable module is attached to a vehicle. Dual-purpose circuitry in the removable module can output electric energy to the motor when the multipurpose connector connects the removable module to the motor. The multipurpose connector can connect the removable module to the electric vehicle supply equipment when the removable module is detached from the vehicle. While the removable module is detached from the vehicle, the dual-purpose circuitry cannot output electric energy to the motor. When the multipurpose connector connects the removable module to the electric vehicle supply equipment, the dual-purpose circuitry can receive electric power from the electric vehicle supply equipment.

Abstract: A system generates haptic feedback in an electric vehicle. The system comprises a frame, an energy storage device, and a wheel rotatably coupled to the frame. A motor receives power from the energy storage device and provides torque to the wheel. A controller determines a first operational state of the electric vehicle and transmits a first torque signal to the motor to control the motor to transmit first torque levels to the wheel to propel the electric vehicle. The controller determines a second operational state of the electric vehicle and transmits a second torque signal to the motor assembly. The motor assembly transmits second torque levels to the wheel to generate haptic feedback. The second torque signal is based on the second operational state of the electric vehicle and a torque profile stored in the memory, where the torque profile defines an irregular-shaped periodic waveform (e.g., a heartbeat rhythm).

Abstract: 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.

Abstract: Methods, systems, and apparatuses for motor hotspot identification. One system includes a first motor installed in a vehicle, the first motor including a stator having at least one stator winding corresponding to one phase of the first motor. The system also includes a first set of temperature sensors coupled to the first motor and a controller. The controller receives a motor operating condition signal of the first motor, accesses a stored correlation model, and generates hypothetical temperature measurement data for a hypothetical temperature sensor of the first motor based on the stored correlation model and the motor operating condition signal. The stored correlation model is generated based on motor operating condition signals associated with a second motor operating in a test environment. In response to identifying a hotspot within the first motor based on the hypothetical temperature measurement data, the controller modifies operation of the first motor.

Abstract: A charger including a charging interface and a converter coupled to the charging interface. The converter includes a first plurality of switching transistors coupled to the charging interface and a transformer including a primary winding, a secondary winding, and an auxiliary winding. The primary winding is coupled to the first plurality of switching transistors. A second plurality of switching transistors is coupled between the secondary winding and a battery interface. An auxiliary system interface is coupled to the auxiliary winding. A controller is configured to control the first plurality of switching transistors and the second plurality of switching transistors to generate a first signal at the battery interface and a second signal at the auxiliary system interface.

Abstract: Systems and methods for operating an electric motor of a two-wheeled vehicle. One method includes detecting a position of a drive torque control included in the vehicle, detecting a position of a regenerative brake control included in the vehicle, mapping the detected position of the drive torque control to a requested driving torque, mapping the position of the regenerative brake control to a requested braking torque, determining, with an electronic control unit, a torque command based on the requested driving torque and the requested torque, and transmitting the torque command to an electric motor included in the vehicle.
