Patent number: 11878693Abstract: Described herein are electric vehicles comprising power distribution systems and methods of operating thereof. Specifically, a power distribution system is mechanically coupled to an electric motor, a road wheel, and an auxiliary unit. This system is configured to switch among multiple operating modes and selectively transfer mechanical power among the electric motor, wheel, and auxiliary unit. For example, the power distribution system is configured to transfer mechanical power between the electric motor and the road wheel, but not the auxiliary unit, when switched to a wheel operating mode. The power distribution system is configured to transfer mechanical power between the electric motor and the auxiliary unit, but not the road wheel, when switched to an auxiliary operating mode. The power distribution system is configured to transfer mechanical power between the electric motor, the auxiliary unit, and the road wheel when the system is switched to a combined operating mode.Type: GrantFiled: June 12, 2023Date of Patent: January 23, 2024Assignee: DIMAAG-AI, Inc.Inventors: Ian Wright, David Kieke

Patent number: 11784369Abstract: Described herein are swappable battery modules comprising immersion-thermally controlled prismatic battery cells and methods of operating thereof. A module comprises a tubular enclosure attached (e.g., glued) to different surfaces of the cells and forming two fluid channels with one side of the cells and two additional fluid channels with the opposite side. The module also comprises a first end plate, which is attached to the tubular enclosure and comprises two electrical terminals for connecting to an electric vehicle (EV) and/or external charger. The first end plate also comprises a first fluidic port (fluidically coupled with two fluid channels) and a second fluidic port (fluidically coupled to the remaining two fluid channels), both are configured to form fluidic coupling to the electric vehicle and/or the external charger. The module also comprises a second end plate that fluidically interconnects paid fluid channels from different cell sides.Type: GrantFiled: March 13, 2023Date of Patent: October 10, 2023Assignee: DIMAAG-AI, Inc.Inventors: Ian Wright, David Kieke

Patent number: 10260607Abstract: Components, subassemblies, systems, and/or methods for continuously variable transmissions (CVT) having a variator provided with a plurality of tilting, traction planets and traction rings are described. In one embodiment, a variator is coupled to a rangebox to provide multiple operating modes. In another embodiment, a hydraulic system is configured to control the transmission ratio of the variator and the rangebox. Shift-cam-and-sun subassemblies can be used to facilitate shifting of the transmission ratio of a CVT. A transmission housing and bell housing can be adapted to house components of a CVT and, in some embodiments, to cooperate with other components of the CVT to support operation and/or functionality of the CVT. Related devices include, for example, a pivot arm, a control feedback mechanism, axial force generation and management mechanisms, a control valve integral with an input shaft, a pivot pin hub, and a rotatable carrier configured to support planet-pivot arm assemblies.Type: GrantFiled: June 20, 2016Date of Patent: April 16, 2019Assignee: Fallbrook Intellectual Property Company LLCInventors: Jeremy Carter, Charles B. Lohr, Brad P. Pohl, David Kieke

Publication number: 20180372199Abstract: Devices and methods are provided herein for the transmission of power in motor vehicles. Power can be transmitted in a smoother and more efficient manner by splitting torque into two or more torque paths. A continuously variable transmission is provided with a ball variator assembly, a dual pinion planetary gearset coupled thereto and an arrangement of rotatable shafts with multiple gears and clutches that extend the ratio range of the variator. In some embodiments, a launch gear CVP bypass enables is provided.Type: ApplicationFiled: December 16, 2016Publication date: December 27, 2018Applicant: DANA LIMITEDInventors: DAVID KIEKE, CHARLES B.
