Patent number: 11929632Abstract: 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.Type: GrantFiled: January 27, 2021Date of Patent: March 12, 2024Assignee: LiveWire EV, LLCInventors: Hamidreza Hafezinasab, William Albert Stinnett

Patent number: 11866117Abstract: 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.Type: GrantFiled: January 16, 2020Date of Patent: January 9, 2024Assignee: LiveWire EV, LLCInventors: Andrew Alfred Knitt, James Joseph Williams, Samuel Nicholas Reitinger, James Sadauckas

Patent number: 11858580Abstract: An electric vehicle includes a frame, a wheel coupled to the frame, and a battery assembly including a housing supported by the frame. The housing includes a top side and a bottom side opposite the top side. A drive assembly of the electric vehicle is at least partially enclosed within a drive housing unit. The drive assembly includes a motor configured to receive power from the battery assembly and a gear assembly configured to transmit torque from the motor to the wheel. The drive housing unit is positioned below the bottom side of the housing.Type: GrantFiled: March 6, 2023Date of Patent: January 2, 2024Assignee: LiveWire EV, LLCInventors: David Isaac Aunkst, Samuel Nicholas Reitinger, Eric James Klumpp, Ronald Hurth, Ben Matthew Lund

Patent number: 11708126Abstract: 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.Type: GrantFiled: February 23, 2022Date of Patent: July 25, 2023Assignee: LiveWire EV, LLCInventors: Samuel Nicholas Reitinger, Eric Konkel, Mark Gales, Jared Peter Thede

Patent number: 11639182Abstract: 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).Type: GrantFiled: January 22, 2021Date of Patent: May 2, 2023Assignee: LiveWire EV, LLCInventors: David Isaac Aunkst, Eric James Klumpp, Tim Monahan, Sean M.
