Publication number: 20210359523Abstract: Control of an energy storage and provisioning system is disclosed, including a method in which electrical power is received from a power generator in an energy storage system having energy storage cells. Each of the energy storage cells has switching elements selectively operable to connect with terminals of other energy storage cells. The method further includes determining a condition of a number of the energy storage cells via electrical measurement; and grouping, by controlling operation of the switching elements, a subset of the energy storage cells into a topology configuration based on a condition of individual cells of the subset of energy storage cells. The method further includes storing the received electrical power into the subset of energy storage cells arranged into the topology configuration to optimize storage of the electrical power received from the power generator.Type: ApplicationFiled: September 4, 2019Publication date: November 18, 2021Inventors: Jonathan Gale Ritchey, Kent Thoresen

Publication number: 20210249981Abstract: A reconfigurable rotating electric machine having a rotor to rotate in association with a stator. Coils are arranged to form the windings of one or more phases. Each coil or group of coils has a pair of terminals to receive an electrical input. Switches are arranged to connect each coil or group of coils in series or parallel with another coil or group of coils to form defined coil topology configurations. A processor has memory storing settings to determine a state of each of the switches for each of the defined coil topology configurations. The switches are controllable to connect the coils into a force expansion topology configuration to form an electrical machine having two, four, or more virtual poles.Type: ApplicationFiled: September 4, 2019Publication date: August 12, 2021Inventors: Jonathan Gale Ritchey, Torsten Broeer, Zachary Adam Golding Hardat, Basem M.

Patent number: 9812981Abstract: One or more variable configuration controller (VCC) systems may produce various combinations of series or parallel couplings of coils, winding or inductive elements of an electric machine such as a generator and/or electric motor. The VCC systems include a plurality of bridge rectifiers, and a first number of switches operated to selectively couple respective pairs of coils in series from parallel on an AC side of the bridge rectifiers. The bridge rectifiers provide for automatic electrical isolation of coils on occurrence of open circuit, low voltage or short circuit conditions. A second number of switches with different performance characteristics (e.g., speed, loss) than the first number of switches may be coupled in parallel with respective ones of the first number of switches. Power factor correction may be used.Type: GrantFiled: June 3, 2014Date of Patent: November 7, 2017Assignee: Exro Technologies Inc.Inventors: Jonathan Gale Ritchey, Mitchell Gordon Burton, Ryan Biffard

Patent number: 9685827Abstract: A polyphasic multi-coil generator includes a drive shaft, at least first and second rotors rigidly mounted on the drive shaft so as to simultaneously synchronously rotate with rotation of the drive shaft, and at least one stator sandwiched between the first and second rotors. A stator array on the stator has an array of electrically conductive coils mounted to the stator in a first angular orientation about the drive shaft. The rotors each have an array of magnets which are circumferentially equally spaced around the rotor and located at the same radially spacing with respect to the centre of the rotor and the drive shaft at a first angular orientation relative to the drive shaft. The arrays of magnets on adjacent rotors are off-set by an angular offset relative to one another.Type: GrantFiled: December 4, 2013Date of Patent: June 20, 2017Assignee: EXRO TECHNOLOGIES INC.Inventor: Jonathan Gale Ritchey

Patent number: 9590468Abstract: An electric machine may employ a distributed bearing, for example spaced radially outwardly of a longitudinal center of a rotor and stator assembly. The distributed bearing may take the form of a wire race bearing, which positions a rotor assembly relative to a stator assembly to maintain an air gap therebetween. The rotor assembly may be concentrically located within the stator assembly. Electrically insulative fasteners may couple a race assembly to the stator or rotor assembly. Compensation fastener assemblies may couple the wire race assembly to the rotor or stator assembly, to compensate for differential expansion for instance thermal differential expansion along a longitudinal axis of the electric machine. The electric machines may be arranged in series, for example with drive shafts arranged along a common axis, and may be coupled to the same source of motion (e.g., propeller of wind turbine, without or with a gear box).Type: GrantFiled: October 8, 2013Date of Patent: March 7, 2017Assignee: EXRO TECHNOLOGIES INC.Inventors: Jonathan Gale Ritchey, Daryl Anton Wagner
