[0017] Following below are more detailed descriptions of various concepts related to, and implementations of, methods, apparatuses, and systems of a multiple battery drive system. The various concepts introduced above and discussed in greater detail below may be implemented in any of numerous ways. The drive system described herein can be applied to systems with two batteries, three batteries, four batteries, or any number of batteries.

[0018] This disclosure is generally directed to techniques for operating a motor of a microvehicle with multiple battery packs. Micro-vehicles, such as electric bicycles or bikes, electric scooters, electric skateboards, or electric one-wheels, can have one or multiple batteries or battery packs. Because the battery packs can be at different states of charge, and have different voltages, if two battery packs are connected in parallel for simultaneous use, one battery can short into the other battery. Even if both battery packs are fully charged, the different characteristic of the battery packs can cause battery packs to discharge at different rates, and therefore, even if the voltage of the battery packs is the same at one point in time, at a future time, the voltages may be different and one battery pack can short into another battery pack. Therefore, vehicles with multiple battery packs can use the battery packs one at a time, and not simultaneously.

[0019] In this regard, the torque of a motor of the vehicle can be limited by the current output that a single battery pack can provide the motor. For example, a vehicle can switch back and forth from utilizing a first battery pack to drive a motor and utilizing a second battery pack to drive the motor instead of utilizing both battery packs simultaneously. The vehicle can begin utilizing a battery pack with the greatest state of charge or highest output voltage. The vehicle can continue utilizing that battery pack until the state of charge or voltage of the battery pack becomes less than another battery pack. Then, the vehicle can switch from utilizing the first battery pack to utilizing the second battery pack. The battery packs that are not being used by the vehicle can provide range extension for the vehicle, but cannot provide any additional power boost or torque boost for the motor.

[0020] To solve these and other technical problems, the present solution can include a dual or multiple battery drive system that can be driven by two battery packs at once (e.g.,simultaneously, concurrently, concomitantly, together, or during a common operating period of time). A single motor can include a first set of windings and a second set of windings. The first set of windings and the second set of windings can be electrically isolated. However, the first set of windings and the second set of windings can be part of the same magnetic circuit that causes a rotor of the motor to spin, rotate, or revolve. The first set of windings can include three windings for three phases of an alternating current (AC) signal. The second set of windings can include three windings for three phases of a second AC signal.

[0021] The motor can include dual or multiple windings on a single stator. For example, the stator can include slots for the windings. The slots of the stator can include dual or multiple windings, for example, the slots can include windings of the first set of windings and windings of the second set of windings. Furthermore, the motor can include multiple stators, one stator for each set of windings. For example, the motor could include a first stator with the first windings and a second stator with the second windings. The first and second stators can be stacked or aligned axially, e.g., along a common longitudinal axis.

[0022] The first set of windings can be electrically coupled with the first battery pack. The first set of windings can be electrically coupled with the first battery pack through a first inverter of a controller. The output of the first inverter can connect to the first set of windings. The second set of windings can be electrically coupled with the second battery pack. The second set of windings can be electrically coupled with the second battery pack through a second inverter of the controller. The output of the second inverter can connect to the second set of windings. The first battery pack and the second battery pack can feed to a single controller. The controller can have the two inverter power stages and control the inverter power stages with a data processing system, microprocessor, microcontroller, or analog control circuit.

[0023] The motor can be driven by first power provided by the first battery pack and second power provided by the second battery pack simultaneously, concurrently, or during the same time period. Because the first battery pack and the second battery pack are not directly electrically coupled, the two battery packs can concurrently provide power to the first winding and the second winding respectively to drive the motor. In this regard, even if the two battery packs are at different states of charge, the battery packs can be used to simultaneously to drive a single motor.

[0024] By operating the motor with two battery packs simultaneously, the controller can operate the motor to provide increased power or torque. By using both battery packs simultaneously, the drive train of the vehicle can operate with an increased level of power. This can assist a rider, user, or driver in accelerating, starting from a stop, or climbing a hill. The simultaneous use of multiple batteries to power the motor can allow the vehicle to drive at a faster rate. Furthermore, the controller can control the power provided by each battery pack to the motor such that the range of the vehicle and the torque of the motor to be extended, optimized, increased, or improved. In this regard, this technical solution can allow for multiple batteries to be used together, even if there is a mismatch in state of charge of the batteries, to provide a higher power output and greater performance than using a single battery.

[0025] Referring now to FIG. 1, among others, a system 100 of a vehicle that powers a motor 135 with multiple batteries is shown. The system 100 can be a system, apparatus, or device. The system 100 can be a vehicle or can be a system of a vehicle. The vehicle can be an electric bike (two wheel bicycle, unicycle, tricycle), an electric scooter, an electric skateboard, an electric one-wheel. The vehicle can be an electric car, electric truck, electric delivery vehicle, electric semi-truck, electric boat, electric submarine, an electric drone or plane, an electric helicopter.

[0026] The system 100 can include at least one first battery 105 and at least one second battery 110. The first battery 105 and the second battery 110 can be separate battery cells, separate battery modules, or separate battery packs. The first battery 105 and the second battery 110 can have the same or different states of charge, or different capacities. The first battery 105 and the second battery 110 can be or include lithium-ion batteries that include an LFP (lithium iron phosphate) chemistry, an LMFP (lithium manganese iron phosphate) chemistry, an NMC (Nickel Manganese Cobalt) chemistry, an NCA (Nickel Cobalt Aluminum) chemistry, an OLO (Over Lithiated Oxide) chemistry, or an LCO (lithium cobalt oxide) chemistry for a cathode layer. The battery 105 or the battery 110 can include lithium-ion batteries that can include a graphite chemistry, a silicon-graphite chemistry, or a lithium metal chemistry for the anode layer). The first battery 105 and the second battery 110 can have the same or different chemical compositions. The first battery 105 and the second battery 110 can include the same number or a different number of battery cells or battery modules. The first battery 105 and the second battery 110 can include the same or different capacities.

[0027] The system 100 can include at least one controller 115. The controller 115 can include at least one data processing system 120. The data processing system 120 can be or include at least one processor, memory device, microcontroller, processor, microprocessor, logic circuit, or set of logic gates. The controller can include at least one first inverter 125 and at least one second inverter 130. The first inverter 125 and the second inverter 130 can control the delivery of power to the motor 135. The first inverter 125 and the second inverter 130 can control the frequency of power supplied to the motor 135. The first inverter 125 and the second inverter 130 can control whether the motor 135 rotates. The first inverter 1235 and the second inverter 130 can control the speed at which the motor 135 rotates. The first inverter 125 and the second inverter 130 can control a torque provided by the motor 135.

[0028] The first battery 105 can be coupled, connected, electrically coupled, or attached to the controller 115. The second battery 110 can be coupled, connected, electrically coupled, or attached to the controller 115. For example, at least one wire, cable, busbar, switch, or electrical component can couple the first battery 105 with the first inverter 125. At least one wire, cable, busbar, switch, or electrical component can couple the second battery 110 with the second inverter 130.

[0029] The first inverter 125 and the second inverter 130 can convert a direct current (DC) signal into an alternative current (AC) signal. For example the first inverter 125 can convert a first DC signal or first DC power received from the first battery 105 into a first AC signal or first AC power. The first AC signal can be a square wave, a sine wave, a sinusoidal pulse wave modulated (PWM) signal. The second inverter 130 can convert a second DC signal or second DC power received from the second battery 110 into a second AC signal or second AC power. The second AC signal can be a square wave, a sine wave, a sinusoidal pulse wave modulated (PWM) signal. The first inverter 125 can provide the first AC signal or first AC power to the motor 135. The second inverter 130 can provide the second AC signal or second AC power to the motor 135. The first inverter 125 and the second inverter 130 can each include rectifiers, smoothing units or filters, or inverter units.

[0030] The data processing system 120 can control, operate, or adjust the first inverter 125 and the second inverter 130. For example, the data processing system 120 can control the frequency of the first AC signal generated by the first inverter 125. The data processing system 120 can control the frequency of the second AC signal generated by the second inverter 130. The data processing system 120 can control, adjust, or output at least one voltage, current,pulse wave modulated (PWM) signal that controls the first inverter 125 and the second inverter 130. The data processing system can provide a first output signal to the first inverter 125 to control the frequency of the first AC signal output by the first inverter. The data processing system can provide a second output signal to the second inverter 130 to control the frequency of the first AC signal output by the first inverter.

[0031] The system 100 can include at least one motor 135. The motor 135 can be an AC or DC motor. The motor 135 can be a synchronous motor or an induction motor, such as a single phase induction motor or a three phase induction motor. The motor can include at least one first winding set 140 and at least one second winding set 145. The first winding set 140 (or first set of windings) can be coupled with the first battery 105 via the first inverter 125. The second winding set 145 (or second set of windings) can be coupled with the second battery 110 via the second inverter 130. Both the first winding set 140 and the second winding set 145 can be disposed within a single motor 135, e.g., within an enclosure, case, or housing of the motor 135. Furthermore, the first winding set 140 and the second winding set 145 can simultaneously or concurrently conduct current within the motor or within a magnetic field of the motor 135. A rotor of the motor or drive shaft of the motor can be rotated, turned, or spun by the first winding set 140 and the second winding set 145.

[0032] The first winding set 140 can include one or multiple windings, such as a first windings for a first phase of an AC signal, a second windings for a second phase of an AC signal, or a third set of windings for a third phase of a an AC signal. The second winding set 145 can include one or multiple windings, such as a first set of windings for a first phase of an AC signal, a second set of windings for a second phase of an AC signal, or a third set of windings for a third phase of a an AC signal. For example, the first AC signal output by the first inverter 125 can be a 3 -phase signal. The second AC signal output by the second inverter 130 can be a 3 -phase signal. Each phase of the phases of the first AC signal can be provided by the first inverter 125 to one of the windings of the first winding set 140. Each phase of the phases of the second AC signal can be provided by the second inverter 130 to one of the windings of the second winding set 145.

[0033] The first winding set 140 can be electrically coupled, connected, or attached to the first inverter 125. For example, an output of the first inverter 125 can be coupled to an input of the first winding set 140. The first inverter 125 can output a first AC signal with one or multiple phases. A first phase of the first AC signal can be coupled with first windings of thefirst winding set 140, a second phase of the first AC signal can be coupled with second windings of the first winding set 140, and a third phase of the first AC signal can be coupled with the third windings of the first winding set 140. The second winding set 145 can be electrically coupled, connected, or attached to the second inverter 130. For example, an output of the second inverter 130 can be coupled to an input of the second winding set 145. The second inverter 130 can output a second AC signal with one or multiple phases. A first phase of the second AC signal can be coupled with first windings of the second winding set 145, a second phase of the second AC signal can be coupled with second windings of the second winding set 145, and a third phase of the second AC signal can be coupled with the third windings of the second winding set 145.

[0034] The first inverter 125 and the second inverter 130 can simultaneously or concurrently provide power or current to the motor 135. For example, the first inverter 125 can provide first power of the first battery 105 to the first winding set 140 during a time period and the second inverter 130 can provide second power of the second battery 110 to the second winding set 145 during the same time period. Providing the first power to the first winding set 140 and the second power to the second winding set 145 during the time period can include simultaneously or concurrently providing the first power to the first winding set 140 and the second power to the second winding set 145 for at least one point in time or at least one portion of time of the time period. For example, the first inverter 125 can provide the first power to the first winding set 140 during the entire duration of the time period and the second inverter 130 can provide the second power to the second winding set 145 during the entire duration of the time period. For example, the first inverter 125 and the second inverter 130 can simultaneously or concurrently provide a first AC signal or first AC power to the first winding set 140 and a second AC signal or second AC power to the second winding set 145.

[0035] The electrical circuits of the first battery 105, the first inverter 125, and the first winding set 140 can be electrically separate, or partially separate, from the electrical circuits of the second battery 110, the second inverter 130, and the second winding set 145. In this regard, the first battery 105 and the second battery 110 can be decoupled and not discharge or short into each other. However, because the power of the first battery 105 and the second battery 110 are provided to separate winding sets 140 and 145, the first inverter 125 and the second inverter 130 can power or drive the motor 135 with both of the batteries 105 and 110 simultaneously regardless of the state of charge or battery voltage of the batteries 105 and 110.For example, the first inverter 125 can provide first power of the first winding set 140 to the first battery 105 and the second inverter 130 can provide second power of the second battery 110 to the second winding set 145 when the first battery 105 and the second battery 110 are at the same state of charge or approximately at the same state of charge and when the first battery 105 and the second battery 110 are at different states of charge.

[0036] If the controller 115 operates the motor 135 with only the first battery 105 or only the second battery 110, the vehicle can have a first range or total distance that the vehicle can travel. Furthermore, the motor 135 can provide a first torque or first maximum torque level to drive the vehicle. However, by simultaneously driving the first winding set 140 based on power of the first battery 105 and the second winding set 145 based on power of the second battery 110, torque that the motor 135 can output or provide can be increased, e.g., a maximum level of torque of the motor 135 can be increased. Furthermore, the total range of the vehicle can be increased.

[0037] The controller 115 can receive measurements or characteristics of the first battery 105 and the second battery 110. For example, the controller 115 can receive measurements from sensors of the first battery 105 or the second battery 110. For example, the controller 115 can receive a first voltage of the first battery 105 from a voltage sensor of the first battery 105. The controller 115 can receive a first temperature of the first battery 105 from a first temperature sensor of the first battery 105. The controller 115 can determine or measure a first state of charge of the first battery 105 via one or multiple first sensor measurements of one or multiple first sensors of the first battery 105. Furthermore, the controller 115 can receive a second voltage of the second battery 110 from a second voltage sensor of the second battery 110. The controller 115 can receive a second temperature of the second battery 110 from a second temperature sensor of the second battery 110. The controller 115 can determine or measure a second state of charge of the second battery 110 via one or multiple second sensor measurements of one or multiple second sensors of the second battery 110.

[0038] The controller 115 can use the characteristics of the first battery 105 and the second battery 110 to determine a frequency of the first AC signal for the first inverter 125 to provide to the first winding set 140 and a frequency of the second AC signal for the second inverter 130 to provide to the second winding set 145. The controller 115 can determine, based on an optimization or control algorithm, a frequency to provide to the first winding set 140 and a frequency to provide to the second winding set 145 to increase, boost, maximize, or optimizethe torque of the motor 135 or the range of the vehicle. The controller 115 can detect, based on feedback data or sensor data of the motor 135, to increase the torque of the motor 135 by control the frequency or amplitude of the AC signal provided to the first winding set 140 or the second winding set 145.

[0039] Referring now to FIG. 2, a stator 205 of a motor 135 with a first set of windings 140 for the first battery 105 and a second set of windings 145 for the second battery 110 is shown. The stator 205 can include at least one slot 215. The slots 215 can be cutaways, grooves, openings, or spaces between members 210 of the stator 205. The members 210 can be cylinder shaped, rectangular solid shaped, pole shaped, spoke shaped, or free form shaped. The windings of the first winding set 140 and the windings of the second winding set 145 can be wound in the slots 215 between the members 210. At least one winding of the first winding set 140 and at least one winding of the second winding set 145 can be wound at least partially around the members 210.

[0040] The windings of the first winding set 140 can be wound over a length, section, or area 225 of the member 210. For example, the windings of the first winding set 140 can be wound over a length along the longitudinal axis 235 of the member 210. The windings of the second winding set 145 can be wound over a length or area 220 of the member 210. The first winding set 140 and the second winding set 145 can be separated by a length or distance 230. The first winding set 140 and the second winding set 145 may not be separated by any distance at all. The second length 220 and the first length 225 can be the same length or different lengths. The second length 220 and the first length 225 can be one inch to three inches. The second length 220 and the first length 225 can be half an inch to three and a half inches. The second length 220 and the first length 225 can be a quarter inch to four inches. The distance 230 can be an eighth inch to a quarter inch long. The distance 230 can be a sixteenth inch to a half inch long. The distance 230 can be less than a sixteenth inch or greater than a half inch.

[0041] The first area 225 can be positioned a first distance from an end 240. The second area 220 can be positioned a second distance from the end 240. The end 240 can be an end, edge, or outer surface of the member 210. The first area 225 can be positioned a first distance from the end 240 of the stator 205, which can be a shorter distance than a second distance that the second area 220 is positioned from the end 240 of the stator 205. The second distance that the second area 220 is positioned from the end 240 of the stator 205 can be greater than a first distance than the first area 225 is positioned from the end 240 of the stator 205.

[0042] In some implementations, the first winding set 140 and the second winding set 145 are wound over the same area, length, or section of the member 210. For example, the first winding set 140 and the second winding set 145 can be wound together and overlap each other over a section of the member 210. For example, the first windings 140 could be wound first and the second set of windings 145 wound over the first windings 140. For example, the first windings 140 and the second set of windings 145 can be mixed together and overlap each other. In some implementations, the winding sets 140 and / or 145 can have non-conductive coatings or insulators (such as a thermoplastic compound or thermoplastic rubber) so that the windings 140 and 145 are electrically separate.

[0043] The gauge of the wire of the first winding set 140 and the wire of the second winding set 145 can be different, the same, or approximately the same. The gauge of the wires of the first winding set 225 and the second winding set 220 can be based, selected, or disposed in the motor 135 based on a capacity of the first battery 105 and the second battery 110 and / or based on nominal or maximum current level that the batteries 105 and 110 provide. For example, the larger the capacity of the first battery 105 and the second battery 110, and the greater the amount the current that the first battery 105 and the second battery 110 can provide, the lower the gauge of the wires of the first winding set 140 and the second winding set 145. Because the first battery 105 and the second battery 110 can be different capacities and provide different amounts of current, the gauge of the first winding set 140 and the gauge of the second winding set 145 can be different, e.g., the gauge of wires of the first winding set 140 can be lower than the gauge of wires of the second winding set 145 if the first battery 105 has a higher capacity than the second battery 110.

[0044] Referring now to FIG. 3, among others, the motor 135 including a stator 205 with the first set of windings 140 for the first battery 105 and the second set of windings 145 for a second battery 110 is shown. The motor 135 can include at least one rotor 305. The rotor 305 can be cylindrically shaped. The rotor 305 can be ring shaped. The rotor 305 can include a hollow inner portion, e.g., a cylindrically shaped cavity, space, or open area. The rotor 305 can circumscribe, encircle, or surround at least a portion of the stator 205. For example, the rotor 305 can be disposed within the inner cylindrical shaped cavity of the rotor 305. The rotor 305 can include at least one magnet 315. The magnets 315 can be disposes on the inner surface of the rotor 305. For example, the magnets 315 can include a curved surface the conforms with the curved inner surface of the rotor 305. The magnets 315 can include ceramic magnets,alnico magnetics, neodymium magnets, samarium cobalt magnets, etc. The magnets 315 can be disposed and spaced around the inner surface of the rotor 305 and surround at least a portion of the stator 205. The magnets 315 can create a magnetic field within the motor 135.

[0045] The first inverter 125 can provide first power of the first battery 105 to the first winding set 140 and the second inventor 130 can provide second power of the second battery 110 to the second winding set 145. The current that flows through the first winding set 140 and the second winding set 145 in the motor 135 can cause the rotor 205 to rotate. For example, a current that runs through the first winding set 140 and the second winding set 145 within the magnetic field created by the magnets 315 can cause the rotor 305 to rotate, spin, accelerate, decelerate, or turn. The rotor 305 can rotate responsive to current flowing through one of the first winding set 140 and the second winding set 145. The rotor 305 can rotate responsive to first current flowing in the first winding set 140 and second current simultaneously or concurrently flowing in the second winding set 145.

[0046] The motor 135 can include multiple members 210 that each include windings of the first winding set 140 and the second winding set 145 that conduct a particular phase of the first AC signal or the second AC signal. At least two members 210 can include windings of the first winding set 140 and winding of the second winding set 145 that conduct current of a particular phase of the first AC signal or the second AC signal. The windings of each member 210 can conduct a current of one phase of a 3 -phase AC signal. The first winding set 140 can include windings 140a for a first phase of the first AC signal, windings 140b for a second phase of the first AC signal, and windings 140c for a third phase of the first AC signal. The second winding set 145 can include windings 145a for a first phase of the second AC signal, windings 145b for a second phase of the second AC signal, and windings 145c for a third phase of the second AC signal.

[0047] For example, the first inverter 125 can apply or provide a first phase of the first AC signal to the windings 140a.

For example, the first stator 205 can include a first longitudinal axis 510 and the second stator 205 can include a second longitudinal axis 510. The first longitudinal axis 510 and the second longitudinal axis 510 can be aligned. The longitudinal axis 510 of the first stator 205 can be the same longitudinal axis 510 of the second stator 205. In this regard, the first stator 205 and the second stator 205 can be axially stacked. For example, the first stator 205 and the second stator 205 can have longitudinal axes 510 that are aligned. The first stator 205 and the second stator 205 can share the same longitudinal axis 510 or each have a common longitudinal axis 510.

[0055] Even though the first winding set 140 and the second winding set 145 are wound on separate stators 205, the first winding set 140 and the second winding set 145 can simultaneously or concurrently conduct current of the first and second AC signals respectively. The first winding set 140 can conduct current of the first AC signal and the second winding set 145 can conduct current of the second AC signal. By simultaneously conducting current, the first winding 140 and the second winding 145 can both cause the rotor 305 to rotate, spin, turn, or move. The controller 115 can control the first inverter 125 and the second inverter 130 to simultaneously provide power to the first set of windings 140 and the second set of windings 145.

[0061] The bicycle 720 can provide a user interface, such as a graphical user interface or an audio-based user interface. The user interface can include, interface with, or otherwise utilize a touchscreen, keyboard, buttons, knobs, other user interface input devices or display depicted in FIG. 9, for example. Through the user interface, the rider of the bike can input one or more thresholds, view operating parameters of the bicycle 720, or control components of the bicycle 720, among other actions.

[0062] The controller 115 can cause the first battery 105 and the second battery 110 to simultaneously or concurrently provide power to the motor 135 to drive the motor 135. The motor 135 can be coupled with the front wheel or rear wheel of the bicycle 720 via a drive system, e.g., drive chain, gears, or other systems of the vehicle. The controller 115 can operate inverters to cause both the first battery 105 and the second battery 110 to provide power to two sets of coils of the motor 135. For example, the controller 115 can cause the first battery 105 to provide power to a first set of coils of the motor 135 and the second battery 110 to provide second power to a second set of coils of the motor 135. The controller 115 can operate the motor 135 with the power of the first battery 105 and the power of the second battery 110 to drive the front wheel of the bicycle 720 or the rear wheel of the bicycle 720. This can cause the front wheel or the rear wheel of the bicycle 720 to spin or rotate to assist the rider in pedaling the bicycle 720, or to cause the bicycle 720 to move without the rider pedaling the bicycle 720.

[0063] Referring now to FIG. 8, among others, a method 800 of operating a motor of a vehicle with multiple batteries is shown. At least a portion of the method 800 can be performed by the first battery 105, the second battery 110, the controller 115, the data processing system 120, the first inverter 125, the second inverter 130, the motor 135, the first winding set 140, and the second winding set 145. At least a portion of the method 800 can be performed by a processor, a microcontroller, a vehicle, the bicycle 720. At least a portion of the method 800 can be performed by a manufacturing system, apparatus, or device.

The method 800 can include an ACT 805 of coupling first windings. The method 800 can include an ACT810 of coupling second windings. The method 800 can include an ACT 815 of providing power to first windings. The method 800 can include an ACT 820 of providing power to second windings.

[0064] At the ACT 805, the method 800 can including coupling the first windings 140. For example, the method 800 can include electrically coupling or connecting the first winding set 140 with the controller 115. For example, the method 800 can include coupling, via a wire, cable, or conductor, the first winding set 140 with the first inverter 125 of the controller 115. Furthermore, the method 800 can include coupling the first winding set 140 with the first battery 105. For example, the method 800 can include coupling, via a wire, cable, busbar, or conductor, the first inverter 125 with the first battery 105. By coupling the first battery 105 with the first inverter 125, and coupling the first inverter 125 with the first winding set 140, the first battery 105 and the first winding set 140 can be coupled and part of the same electric circuit or connection.

[0065] At the ACT 810, the method 800 can including coupling the second windings 145. For example, the method 800 can include electrically coupling or connecting the second winding set 145 with the controller 115. For example, the method 800 can include coupling, via a wire, cable, or conductor, the second winding set 145 with the second inverter 130 of the controller 115. Furthermore, the method 800 can include coupling the second winding set 145 with the second battery 110. For example, the method 800 can include coupling, via a wire, cable, busbar, or conductor, the second inverter 130 with the second battery 110. By coupling the second battery 110 with the second inverter 130, and coupling the second inverter 130 with the second winding set 144, the second battery 110 and the second winding set 145 can be coupled and part of the same electric circuit or connection.

[0066] At ACT 815, the method 800 can include providing power to the second windings 145. For example, the method 800 can include providing second power of the second battery 110 to the second set of windings 145. For example, the second inverter 130 can provide the second power of the second battery 110 to the second winding set 145. The second inverter 130 can receive DC power from the second battery 110, and output or generate second AC power and provide the second AC power to the second winding set 145. For example, the second inverter 130 can provide a second AC signal to the second winding set 145 to power the second winding set 145.

[0067] The second inverter 130 can provide the second power to the second winding set 145 during a time period, a length of time, or at a point in time. The first inverter 125 can provide second power to the second winding set 145 simultaneously or concurrently with the first inverter 125 providing the first power to the first winding set 140. In this regard, the second inverter 130 can also provide second power to the second winding set 145 during the time period, the length of time, or at the point in time. The method 800 can include providing a the motor 135 or providing the rotor 305 within the motor 135. The rotor 305 can be rotated by the first inverter 125 providing first power to the first winding set 140 and the second inverter 130 simultaneously providing the second power to the second winding set 145. By simultaneously providing the first power to the first winding set 140 and providing the second power to the second winding set 145, the first winding set 140 and the second winding set 145 can simultaneously or concurrently conduct current. Because both the first winding set 140 and the second winding set 145 simultaneously conduct current within a magnetic field of the motor 135 created by magnets 315 of the motor 135, the rotor 305 can rotate, spin, turn, or move based on power of the first battery 105 and the second battery 110.

[0084] Any implementation disclosed herein may be combined with any other implementation or embodiment, and references to “an implementation,” “some implementations,” “one implementation” or the like are not necessarily mutually exclusive and are intended to indicate that a particular feature, structure, or characteristic described in connection with the implementation may be included in at least one implementation or embodiment. Such terms as used herein are not necessarily all referring to the same implementation. Any implementation may be combined with any other implementation, inclusively or exclusively, in any manner consistent with the aspects and implementations disclosed herein.

[0085] References to “or” may be construed as inclusive so that any terms described using “or” may indicate any of a single, more than one, and all of the described terms. References to at least one of a conjunctive list of terms may be construed as an inclusive OR to indicate any of a single, more than one, and all of the described terms. For example, a reference to “at least one of ‘A’ and ‘B’” can include only ‘A’, only ‘B’, as well as both ‘A’ and ‘B’. Such references used in conjunction with “comprising” or other open terminology can include additional items.

[0086] Where technical features in the drawings, detailed description or any claim are followed by reference signs, the reference signs have been included to increase the intelligibility of the drawings, detailed description, and claims. Accordingly, neither the reference signs nor their absence have any limiting effect on the scope of any claim elements.

[0087] Modifications of described elements and acts such as variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations can occur without materially departing from the teachings and advantages of the subject matter disclosed herein. For example, elements shown as integrally formed can be constructed of multiple parts or elements, the position of elements can be reversed or otherwise varied, and the nature or number of discrete elements or positions can be altered or varied. Other substitutions, modifications, changes and omissions can also be made in the design, operating conditions and arrangement of the disclosed elements and operations without departing from the scope of the present disclosure.

[0088] For example, descriptions of positive and negative electrical characteristics may be reversed. Elements described as negative elements can instead be configured as positive elements and elements described as positive elements can instead by configured as negative elements. For example, elements described as having first polarity can instead have a second polarity, and elements described as having a second polarity can instead have a first polarity. Further relative parallel, perpendicular, vertical or other positioning or orientation descriptions include variations within + / - 10% or + / -10 degrees of pure vertical, parallel or perpendicular positioning. References to “approximately,” “substantially” or other terms of degree include variations of + / -10% from the given measurement, unit, or range unless explicitly indicated otherwise. Coupled elements can be electrically, mechanically, or physically coupled with one another directly or with intervening elements. Scope of the systems and methods described herein is thus indicated by the appended claims, rather than the foregoing description, and changes that come within the meaning and range of equivalency of the claims are embraced therein.
