A similar gas engine replacement device 10 is described and illustrated in U.S. Patent Application No. 16 / 551,197, filed August 26, 2019, the entire contents of which are incorporated herein by reference.

[0059] like Figures 1 to 6 As shown, the gas engine replacement device 10 also includes a battery pack 50, which is removably received in a battery socket 54 within the housing 14 to transmit current from the battery pack 50 to the motor 36 via control electronics 42. (See reference...)

The support portion 62 provides a sliding arrangement having a complementary protrusion / recess portion 74 to the battery socket 54 (e.g., Figure 6 The protrusions / recesses 70 (as shown in the diagram) correspond to each other. Figures 4 to 6In the embodiments shown, the protrusion / recess portion 70 of the battery pack 50 is a guide rail, and the protrusion / recess portion 74 of the battery socket 54 is a guide recess. A similar battery pack is described and illustrated in U.S. Patent Publication No. 2019 / 0006980, filed July 2, 2018, the entire contents of which are incorporated herein by reference. In some embodiments, the battery cells 68 have a nominal voltage of up to about 80V. In some embodiments, the battery cells 68 have a nominal voltage of up to about 120V. In some embodiments, the battery pack 50 has a weight of up to about 6 lbs. In some embodiments, each of the battery cells 68 has a diameter of up to 21 mm and a length of up to about 71 mm. In some embodiments, the battery pack 50 includes up to twenty battery cells 68. In some embodiments, the battery cells 68 are connected in series. In some embodiments, the battery cells 68 are operable to output a continuous operating discharge current between about 40A and about 60A. In some embodiments, each of the battery cells 68 has a capacity between about 3.0Ah and about 5.0Ah.

[0060] like Figure 1 , Figure 2 and Figures 9 to 15 As shown, the gas engine replacement device 10 includes one or more remote control interfaces 152, which are supported on the housing 14 for communicating with a remote control device 150. The one or more remote control interfaces 152 may include a wireless interface 152 and / or a wired interface 152. The wired interface 152 may be configured to receive a cable 1024 (…). Figure 10 The cable is configured to connect to the remote control device 150. In some embodiments, the gas engine replacement device 10 includes one or more attachments 154. For example, the attachment 154 for the gas engine replacement device may include a cable reel 154 such that the cable 1024 connected to the remote control device 150 can be retracted onto the cable reel 154 for storage. In some embodiments, the gas engine replacement device 10 includes an electrical interface 154 supported on the housing 14. In some embodiments, the attachment 154 includes a work light that receives power from the battery pack 50 and can be activated by a switch on the remote control device 150 or the gas engine replacement device 10. The electrical interface 156 is configured to provide electrical connection and mechanical support to receive the remote control device 150 or a cable from the remote control device for supplying power from the battery pack 50 to the remote control device 150, thereby powering the remote control device 150 and / or the battery 1014 of the remote control device 150 (see [link to relevant documentation]). Figure 10 )Charge.

[0061] Figure 6A battery socket 54 of a gas engine replacement device 10 according to some embodiments is shown. The battery socket 54 includes a protrusion / recess 74, a second terminal 78, a latching mechanism 82, and a power-off switch 86. The protrusion / recess 74 engages with a protrusion / recess 70 of a battery pack 50 to attach the battery pack 50 to the battery socket 54 of the gas engine replacement device 10. When the battery pack 50 is attached to the gas engine replacement device 10, the second terminal 78 and the first terminal 66 are electrically connected to each other. The latching mechanism 82 protrudes from the surface of the battery socket 54 and is configured to engage the battery pack 50 to maintain engagement between the battery pack 50 and the battery socket 54. Thus, the battery pack 50 can be connected to and supported by the battery socket 54, such that the battery pack 50 can be supported by the housing 14 of the gas engine replacement device 10. In some embodiments, the battery socket 54 is arranged on the housing 14 at a position that creates the maximum possible separation distance between the motor 36 and the battery pack 50 to suppress vibrations transmitted from the motor 36 to the battery pack 50. In some embodiments, the elastomeric member is positioned on the battery pack socket 54 to suppress vibrations transmitted from the motor 36 to the battery pack 50 via the housing 14.

[0062] In other embodiments (not shown), the latching mechanism 82 may be located at different positions (e.g., on the side wall, end wall, top end wall, etc. of the battery socket 54) such that the latching mechanism 82 engages a corresponding structure on the battery pack 50 to maintain engagement between the battery pack 50 and the battery socket 54. The latching mechanism 82 includes a pivotable actuator or handle 90 that operatively engages a latching member 94. The latching member 94 is slidably disposed in a hole 98 in the socket 54 and biased toward a latched position by a biasing member 102 (e.g., a spring) to protrude through the surface of the battery socket 54 and into the cavity of the battery pack 50.

[0063] The latching mechanism 82 also includes a power-off switch 86 (e.g., a microswitch) that facilitates electrically connecting / disconnecting the battery pack 50 from the battery socket 54 during actuation of the handle 90 to remove the latching member 94 from the battery pack 50. The power-off switch 86 can be used to electrically disconnect the battery pack 50 from the gas engine replacement device 10 before removing it from the battery socket 54. The power-off switch 86 is actuated when the latching member 94 moves from the latched position (i.e., when the latching member 94 is fully within the cavity of the battery pack 50) to an intermediate position. The power-off switch 86 is electrically connected to the controller 46 and can generate an interrupt to indicate that the battery pack 50 is being disconnected from the gas engine replacement device 10. When the controller 46 receives the interrupt, the controller 46 initiates power-down operation to safely de-energize the control electronics 42 of the gas engine replacement device 10. A similar latching mechanism and disconnecting switch are described and illustrated in U.S. Patent Publication No. 2019 / 0006980, the entire contents of which are incorporated herein by reference.

[0064] like Figure 7 As shown, motor 36 includes a motor housing 96 having an outer diameter 97, a stator 98 having a nominal outer diameter 102 of at least 80 mm, a rotor 102 having an output shaft 106 and supported for rotation within the stator 98, and a fan 108. A similar motor is described and illustrated in U.S. Patent Publication No. 2019 / 0006980, which is incorporated herein by reference. In some embodiments, motor 36 is a brushless DC motor. In some embodiments, motor 36 has a power output of at least about 2760 W. In some embodiments, the power output of motor 36 may drop below 2760 W during operation. In some embodiments, the diameter 109 of fan 108 is larger than the diameter 97 of motor housing 96. In some embodiments, motor 36 can be stopped with an electronic clutch (not shown) for rapid overload control. In some embodiments, motor 36 has at least 443,619 mm². 3 The volume. In some embodiments, the motor has a weight of approximately 4.6 lb. The housing 14 includes an inlet vent and an outlet vent, such that the motor fan 108 draws air through the inlet vent and along the control electronics 42 to cool the control electronics 42 before the air is exhausted through the outlet vent. Figure 7 In the embodiment shown, motor 36 is an internal rotor motor, but in other embodiments, motor 36 may be an external rotor motor with a nominal outer diameter (i.e., the nominal outer diameter of the rotor) of up to about 80 mm.

[0065] Reference Figure 8Motor 36 can transmit torque to power output shaft 38 in various configurations. In some embodiments, output shaft 106 is also power output shaft 38, allowing motor 36 to directly drive power output shaft 38 without any intermediate gear system. For example, motor 36 can directly drive a high-pole motor. Figure 8 As shown, in other embodiments, the gas engine replacement device 10 includes a gear train 110 that transmits torque from the motor 36 to the power output shaft 38. In some embodiments, the gear train 110 may include a mechanical clutch (not shown) to interrupt torque transmission from the motor 36 to the power output shaft 38. In some embodiments, the gear train 110 may include a planetary gearbox that transmits torque from the output shaft 106 to the power output shaft 38, and the axis of rotation of the output shaft 106 is coaxial with the axis of rotation of the power output shaft 38. In some embodiments, the gear train 110 includes a spur gear that engages with the output shaft 106 of the rotor such that the axis of rotation of the output shaft 106 is offset from and parallel to the axis of rotation of the power output shaft 38. In some embodiments, the gear train 110 includes a bevel gear such that the axis of rotation of the output shaft 106 is perpendicular to the axis of rotation of the power output shaft 38. In other embodiments utilizing bevel gears, the axis of rotation of the output shaft 106 is not perpendicular to, parallel to, or coaxial with the axis of rotation of the power output shaft 38, and the power output shaft 38 protrudes from the flange 34.

[0066] In some embodiments, the gas engine replacement device 10 includes an on / off indicator (not shown). In some embodiments, the gas engine replacement device 10 includes a filter (not shown) to block unloaded debris from the motor 36 and control electronics 42. In some embodiments, the filter includes a dirty filter sensor (not shown) and a self-cleaning mechanism (not shown). In some embodiments, the motor 36 will simulate a gas engine response when encountering resistance (such as slowing down or stopping). In some embodiments, the gas engine replacement device 10 includes a heat sink 202 in the housing 14 for air cooling of the control electronics 42. Figure 1 and Figure 2 In some embodiments, the gas engine replacement device 10 is liquid-cooled.

[0067] In some embodiments, the output shaft 106 of rotor 102 has forward and reverse capabilities, as further described below. In some embodiments, the forward and reverse capabilities are controllable without shifting gears in the gear train 110, unlike gas engines which cannot achieve forward / reverse capabilities without additional transmission mechanisms and time delays. Therefore, the gas engine replacement device 10 offers increased speed, lighter weight, and lower cost. Because the gas engine replacement device 10 has fewer moving parts and no combustion system compared to a gas engine, it also offers additional speed, weight, and cost advantages.

[0068] The gas engine replacement device 10 is capable of operating for extended periods in any orientation (vertical, horizontal, inverted) relative to the ground surface, giving it an advantage over quad-cycle gas engines, which can only operate for shorter periods in one orientation and at a slight tilt. Because the gas engine replacement device 10 does not require gas, oil, or other fluids, it can be inverted or operated, delivered, and stored on any given side without leakage or spillage. The gas engine replacement device 10 can be configured to attach to and drive various types of power equipment, such as, but not limited to, compactors, tampers, injectors, cement mixers, sprayers (e.g., agricultural sprayers), and pump systems.

[0069] In operation, the gas engine replacement device 10 can be used to replace a gas engine system. Specifically, the gas engine replacement device 10 can be mounted to a power unit having a second bolt pattern by aligning a first bolt pattern defined by a plurality of orifices in the flange 34 with a second bolt pattern. In some embodiments, the flange 34 may include one or more intermediate mounting members or adapters disposed between the flange 34 itself and the flange of the power unit having the second bolt pattern, such that the adapter(s) connect the flange 34 to the power unit. In these embodiments, the adapter includes both a second bolt pattern and a first bolt pattern, such that the first bolt pattern of the flange 34 is aligned with the first bolt pattern of the adapter, and the second bolt pattern of the adapter is aligned with the second bolt pattern defined in the power unit, thereby allowing the flange 34 of the gas engine replacement device 10 to be connected to the power unit.

[0070] Alternatively, the gas engine replacement device 10 can be connected to the power equipment using a belt system by providing a belt that operatively connects the power output shaft and the functional parts of the equipment. Therefore, the power output shaft 38 of the gas engine replacement device 10 can be used to drive the equipment.

[0071] During operation, the housing 14 of the gas engine replacement unit 10 can be much cooler than the housing of the internal combustion unit because there is no combustion in the gas engine replacement unit 10. Specifically, when the gas engine unit is operating, the housing of the gas engine unit is 220 degrees Celsius or higher. In contrast, when the gas engine replacement unit 10 is operating, all outer surfaces of the housing 14 are below 95 degrees Celsius.

[0078] Figure 9 A simplified block diagram of a gas engine replacement device 10 according to an example embodiment is shown. Figure 9 As shown, the gas engine replacement device 10 includes an electronic processor 302, a memory 306, a battery pack 50, a power switch network 310, a motor 36, a rotor position sensor 314, a current sensor 318, a user input device 322 (e.g., a trigger or power button), a transceiver 326, an indicator 330 (e.g., a light-emitting diode), and a communication manager 340. In some embodiments, the gas engine replacement device 10 includes a... Figure 9 The components shown are fewer or additional. For example, the gas engine replacement device 10 may include a battery pack fuel gauge, work lights, additional sensors, a cut-off switch, a power-off switch 86, etc. In some embodiments, Figure 9The gas engine replacement device 10 shown includes one or more of the following components: electronic processor 302, memory 306, power switch network 310, rotor position sensor 314, current sensor 318, user input device 322 (e.g., trigger or power button), transceiver 326, and indicator 330 (e.g., light-emitting diode). Figure 3 At least a portion of the control electronics 42 shown, wherein the electronic processor 302 and the memory 306 form Figure 3 At least a portion of the controller 46 shown.

[0079] Memory 306 includes read-only memory (ROM), random access memory (RAM), other non-transitory computer-readable media, or combinations thereof. Electronic processor 302 is configured to communicate with memory 306 to store and retrieve stored data. Electronic processor 302 is configured to receive instructions and data from memory 306 and execute instructions, etc. In particular, electronic processor 302 executes instructions stored in memory 306 to perform the methods described herein.

[0080] As described above, in some embodiments, the battery pack 50 is removably attached to the housing of the gas engine replacement device 10, such that different battery packs 50 can be attached to and removed from the gas engine replacement device 10 to provide different amounts of power to the gas engine replacement device 10. Further descriptions of the battery pack 50 (e.g., nominal voltage, continuous operating discharge current, dimensions, number of battery cells, operation, etc.) and the motor 36 (e.g., power output, dimensions, operation, etc.) are provided above regarding... Figures 1 to 8 supply.

[0081] The power switch network 310 enables the electronic processor 302 to control the operation of the motor 36. Typically, when the user input device 322 is pressed (or otherwise actuated), current is supplied from the battery pack 50 to the motor 36 via the power switch network 310. When the user input device 322 is not pressed (or otherwise actuated), current is not supplied from the battery pack 50 to the motor 36. In some embodiments, the amount by which the user input device 322 is pressed is related to or corresponds to a desired rotational speed of the motor 36. In other embodiments, the amount by which the user input device 322 is pressed is related to or corresponds to a desired torque. In other embodiments, a separate input device (e.g., a slider, dial, etc.) is included on the gas engine replacement device 10 and communicates with the electronic processor 302 to provide a desired rotational speed or torque to the motor 36.

[0082] In some embodiments, the user input device 322 may be a user-actuated forward / reverse switch or a mode selection switch that allows the user to select an operating mode. The user input device 322 provides control signals to the electronic processor 302 to switch the rotation direction of the motor 36 based on the actuation of the user input device 322. In some embodiments, the input may be received from one or more sensors of the gas engine replacement device 10 or a power unit connected to the gas engine replacement device 10. In some embodiments, the input may be received from, for example, a smartphone via a communication network 334.

[0083] In response to receiving a drive request signal from the user input device 322, the electronic processor 302 activates the power switching network 310 to supply power to the motor 36. Through the power switching network 310, the electronic processor 302 controls the amount of current available to the motor 36, thereby controlling the speed and torque output of the motor 36. The power switching network 310 may include a number of field-effect transistors (FETs), bipolar transistors, or other types of electrical switches. For example, the power switching network 310 may include a six-FET bridge that receives pulse-width modulation (PWM) signals from the electronic processor 302 to drive the motor 36.

[0084] Rotor position sensor 314 and current sensor 318 are coupled to electronic processor 302 and transmit various control signals to electronic processor 302 indicative of different parameters of the gas engine replacement device 10 or motor 36. In some embodiments, rotor position sensor 314 includes one or more Hall sensors. In other embodiments, rotor position sensor 314 includes a quadrature encoder attached to motor 36. Rotor position sensor 314 outputs motor feedback information to electronic processor 302, such as indications (e.g., pulses) as the magnets of the rotor of motor 36 rotate past the surface of the Hall sensor. In other embodiments, rotor position sensor 314 includes, for example, a voltage or current sensor that provides an indication of the back electromotive force (back EMF) generated in the motor coils. Electronic processor 302 can determine rotor position, rotor speed, and rotor acceleration based on the back EMF signal received from rotor position sensor 314 (i.e., the voltage or current sensor). Rotor position sensor 314 can be combined with current sensor 318 to form a combined current and rotor position sensor. In this example, the combined sensor provides the current flowing to the active phase coils of motor 36, and also provides the current in one or more of the inactive phase coils of motor 36. Electronic processor 302 measures the current flowing to the motor based on the current flowing to the active phase coils, and measures the motor speed based on the current in the inactive phase coils.

[0085] Based on motor feedback information from rotor position sensor 314, electronic processor 302 can determine the rotor's position, speed, and acceleration. In response to the motor feedback information and signals from user input device 322, electronic processor 302 transmits control signals to control power switching network 310 to drive motor 36. For example, by selectively enabling and disabling the FETs of power switching network 310, power received from battery pack 50 is selectively applied in a cyclic manner to the stator windings of motor 36 to cause the rotor of motor 36 to rotate. Electronic processor 302 uses the motor feedback information to ensure proper timing of the control signals to power switching network 310 and, in some cases, provides closed-loop feedback to control the speed of motor 36 at a desired level. For example, in order to drive motor 36, using motor positioning information from rotor position sensor 314, electronic processor 302 determines the position of rotor magnet relative to stator windings, and (a) excites the next stator winding pair (or multiple stator winding pairs) in a predetermined pattern to provide magnetic force to rotor magnet in the desired rotation direction, and (b) de-excites a previously excited stator winding pair (or multiple stator winding pairs) to prevent the application of magnetic force on rotor magnet opposite to the rotor rotation direction.

[0086] The current sensor 318 monitors or detects the current level of the motor 36 during operation of the gas engine replacement unit 10 and provides a control signal to the electronic processor 302 indicating the detected current level. The electronic processor 302 can use the detected current level to control the power switch network 310, as explained in more detail below.

[0087] Transceiver 326 allows electronic processor 302 to communicate with external device 338 (e.g., a smartphone, tablet, or laptop computer) via wired or wireless communication network 334. In some embodiments, transceiver 326 may include separate transmitting and receiving components. In some embodiments, transceiver 326 may include a wireless adapter attached to gas engine replacement device 10. In some embodiments, transceiver 326 is a wireless transceiver that encodes information received from electronic processor 302 into carrier wireless signals and transmits the encoded wireless signals to external device 338 via communication network 334. Transceiver 326 also decodes information from wireless signals received from external device 338 via communication network 334 and provides the decoded information to electronic processor 302.

[0088] The communication network 334 provides a wired or wireless connection between the gas engine replacement device 10 and the external device 338. The communication network 334 may include a short-range network, such as a Bluetooth network, a Wi-Fi network, or a long-range network, such as the Internet, a cellular network, etc.

[0089] like Figure 9 As shown, indicator 330 is also connected to electronic processor 302 and receives control signals from electronic processor 302 to turn the gas engine replacement device 10 on and off based on different states or otherwise transmit information. Indicator 330 includes, for example, one or more light-emitting diodes (“LEDs”) or a display screen. Indicator 330 can be configured to display the status of gas engine replacement device 10 or information associated with gas engine replacement device. For example, indicator 330 is configured to indicate measured electrical characteristics of gas engine replacement device 10, status of gas engine replacement device 10, mode of gas engine replacement device 10, etc. Indicator 330 may also include elements that transmit information to a user via auditory or tactile output. In some embodiments, indicator 330 includes an eco indicator that indicates the electrical force used by the load during operation.

[0090] Figure 9 The diagram also shows a remote control device 150 and one or more remote control device interfaces 152. One or more remote control device interfaces 152 are coupled to an electronic processor 302. The electronic processor 302 can be configured to receive signals from the remote control device 150 and generate commands for controlling the gas engine replacement device 10 based on information or commands included in the signals received from the remote control device 150. For example, these commands can configure the electronic processor 302 to initiate the operation of the gas engine replacement device 10, control the speed of the motor 36, control the working lights connected to the gas engine replacement device 10, or control the rotation direction of the motor 36. One or more remote control device interfaces 152 may include a wireless interface 152 and / or a wired interface 152 configured to receive information from and / or transmit information to the remote control device 150. In some embodiments, the user input device 322 may include an actuable component for switching the configuration of the gas engine replacement device 10 between a wireless communication mode and a wired communication mode (see also...). Figure 12A and Figure 12B ).

[0091] In some embodiments, the wireless interface 152 may include a wireless receiver and / or transmitter and is configured to communicate with the remote device 150 using one or more wide-area, local-area, or personal area wireless technologies, including Bluetooth Low Energy, Bluetooth, 433MHz, WiFi, infrared, and cellular (e.g., 2G, 3G, 4G, 5G, and LTE). The electronic processor 302 may be configured to communicate and pair with the remote control device 150, for example, to discover and identify the remote control 150 based on user input at the user input device 322 of the gas engine replacement device 10 and / or at the user interface 1018 of the remote control device 150. In some embodiments, the electronic processor 302 communicates with the remote control 150 via a transceiver 326. The remote interface 152 may communicate with the electronic processor 302 via a communication link, such as using UART, SPI, RS485, and / or signals indicating operating status.

[0092] The wired interface 152 can be configured to connect via cable 1024 between the remote control device 150 and the gas engine replacement device 10. Figure 10 The wired interface 152 can communicate information and / or data with the gas engine replacement device 10. In some embodiments, the wired interface 152 can be configured to communicate data and supply electrical power from the battery pack 50 to the remote control device 150. Figure 9 Annex 154 is also shown, such as a reel for retracting cable 1024 into gas engine replacement device 10 or a cord reel on the gas engine replacement device, or a work light. Figure 9 The diagram also shows an electrical interface 156, which is coupled to the battery pack 50 and configured to provide electrical connection and mechanical support for receiving the remote control device 150 or cables (e.g., USB connectors and cables) from the remote control device 150. The electrical interface 156 is configured to supply power from the battery pack 50 to the remote control device 150 for use with its battery 1014 (see [link to documentation]). Figure 10 (Charging and / or powering the remote control device 150.)

[0093] Figure 9The connections between the components of the gas engine replacement device 10 are simplified in the diagram. In reality, the wiring of the gas engine replacement device 10 is more complex because the components are interconnected via several lines for power and control signals. For example, each FET of the power switch network 310 is connected to the electronic processor 302 via a control line; each FET of the power switch network 310 is connected to a terminal of the motor 36; the power lines from the battery pack 50 to the power switch network 310 include positive and negative / ground lines; etc. Additionally, the power lines may have large gauge / diameter to handle increased current. Furthermore, although not shown, additional control signal lines and power lines are used to interconnect additional components of the gas engine replacement device 10.

[0096] The electronic processor 1010 is coupled to one or more communication interfaces, including a wireless interface 1020 and / or a wired interface 1022.

The wired interface 1022 is configured to receive a cable 1024, which is configured to provide a connection between the remote control device 150 and the gas engine replacement device 10 via a remote interface 152. In some embodiments, the cable 1024 includes a medium carrying information such as data to and / or from the remote control device 150 (e.g., from and / or to the electronic controller 302 of the gas engine replacement device 10) and delivering power from the battery 50 to the remote control device 150 to enable its operation. As described above, the remote control 150 and the gas engine replacement device 10 can communicate wirelessly using one or more of wide-area, local-area, or personal area wireless technologies, including Bluetooth Low Energy, Bluetooth, 433MHz, WiFi, infrared, and cellular (e.g., 2G, 3G, 4G, 5G, and LTE). The electronic processor 1010 can be configured to communicate and pair with the gas engine replacement device 10, for example, to discover and identify the gas engine replacement device 10 based on user input at the user interface 1018 of the remote control device 150 and / or the user input device 322 of the gas engine replacement device 10. In some embodiments, the electronic processor 1018 communicates with the gas engine replacement device 10 via a wireless interface 1020.

[0097] An electronic processor 1010 is coupled to one or more user interfaces 1018 and configured to receive user input via one or more user interfaces 1018. The electronic processor 1010 is configured to generate control signals based on the user input received via one or more user interfaces 1018 and transmit the control signals to the gas engine replacement device 10 via a wireless interface 1020 or a wired interface 1022. The control signals may include commands, and the electronic controller 302 of the gas engine replacement device 10 may perform responsive actions based on the control signals. For example, the electronic controller 302 may control the engine 36 or other components of the gas engine replacement device 10 based on input received via one or more user interfaces 1018.

[0098] One or more user interfaces 1018 may include a light-emitting diode (LED) indicator 1018A or a series of LED indicators 1018A (see [link to documentation]). Figure 13A This is used to convey the status or (multiple) operational status of the gas engine replacement device 10 or the remote control device 150. One or more user interfaces 1018 may include any suitable display device 1018B (see [link to relevant documentation]). Figure 13AFor example, an LCD display or another type of display. One or more remote interfaces 1018 may be configured to indicate the condition or status of one or more components of the gas engine replacement device 10, or the condition or status of power equipment attached to and driven by the gas engine replacement device 10. For example, one or more user interfaces may be configured to indicate one or more of the following: the charge level of the battery pack 50, the remaining usage time of the battery pack 50, the duty cycle applied to the motor 36, the speed of the motor 36 or the power take-off shaft 38, the torque applied to the motor 36, or the efficiency of the motor 36. In some embodiments, one or more user interfaces 1018 include an interactive display device 1018B, such as a touch screen display device, which can display a graphical user interface and receive user selections to control the gas engine replacement device 10 via the touch screen display device 1018B. In addition, in some embodiments, one or more user interfaces 1018 include a physically actuated input mechanism 1018C (see Figure 13A and Figure 13B Features such as buttons, knobs, dials, sliders, or switches are used for user actuation to initiate control of the gas engine replacement system 10 or the remote control 150. Information displayed on the remote device 150 may be received by the remote device 150 from the electronic processor 302 via the remote interface 152.

[0100] Battery socket 1014 is supported by housing 1110 (see Figure 11The device is configured to receive a battery pack or battery for supplying power to the remote control device 150. In some embodiments, the remote control device 150 includes one or more electrical interfaces 1016 supported by a housing 1110 and receiving power to charge the battery pack received in the battery socket 1014 or to operate the remote control device 150. In some embodiments, the electrical interface 1016 is configured to receive a battery recharge interface 156 of the gas engine replacement device 10 to receive power from the battery pack 50. In other embodiments, the electrical interface 1016 is configured to receive another type of electrical connector. For example, the electrical interfaces 1016 may include a USB port for receiving power via a USB cable. In another example, the electrical interfaces 1016 include an induction coil configured to receive energy transferred from a charging station or induction pad (e.g., at the battery recharge interface 156) via inductive coupling. In some embodiments, the battery or battery pack is removably received by the battery socket 1014 and can be removed and charged in a separate battery charging device.

[0101] In some embodiments, components of the remote control device 150 may be configured to operate with the gas engine replacement engine 10 depending on the type of power equipment attached to and driven by the gas engine replacement device 10. For example, commands for controlling the pump system or for providing feedback on the condition or status of the pump system may differ from commands and feedback for a compactor system or injector system driven by the gas engine replacement device 10. The electronic processor 1010 may be configured to receive one or both of the following: the identity of the designated power equipment attached to and driven by the gas engine replacement engine; and parameters for configuring the remote control device. The electronic processor 1010 may be configured to control one or more user interfaces 1018 for use with the designated power equipment based on the identity of the designated power equipment received from the gas engine replacement device 10 or the parameters for configuring the remote control device 150.

[0102] Figure 14This is a flowchart of a method for controlling a gas engine replacement device 10 using a remote control device 150. In step 1400, communication is established between the remote control device 150 and the gas engine replacement device 10. For example, in some embodiments, the remote control 150 and the gas engine replacement device 10 may wirelessly communicate via a wireless transceiver 1020 and a remote interface 152 using the Bluetooth protocol, and may be configured to discover and pair for communication. In some embodiments, user input at the user interface 1018 of the remote control device 150 and / or at the user input device 322 of the gas engine replacement device 10 may initiate a pairing process, which may include broadcast advertising messages and response messages between the devices. In some embodiments, the remote control device may use another communication technology, such as 433MHz, WiFi, infrared, or cellular, and a pairing process may not be necessary.

[0103] In step 1402, in some embodiments, the remote control device 150 determines the type of power equipment attached to and driven by the gas replacement device 10. For example, the remote control device 150 may receive identifiers or configuration parameters from the gas replacement device 10 that indicate which type of power equipment will be controlled.

[0104] In step 1404, the electronic processor 1010 is configured based on an identifier or configuration parameters received from the gas engine replacement device 10. The electronic processor 1010 can be configured to control one or more user interfaces 1018 for use with a specified power device based on the identity of the designated power device received from the gas engine replacement device 10 or parameters used to configure the remote control device 150. For example, the incremental motor speed control signal may vary depending on the type of power device driven by the gas engine replacement device 10. Furthermore, some power devices may include motor-driven elements that can only rotate in one direction. Therefore, the configuration of the remote device 150 may disable the forward-reverse rotation direction selection feature of the remote device 150, making the allowed rotation direction unchangeable by the user. In another example, the gas engine replacement device 10 may not include a work light or other accessory 154, and the configuration of the remote device 150 may disable the accessory control feature of the remote device 150. Of course, in embodiments of power equipment and gas engine replacement devices 10 that include forward and reverse motor rotation capabilities or controllable accessories, as indicated by the information received at block 1402, the remote device 150 is configured to be able to control these features in block 1404. In other embodiments, the remote control device may be pre-configured, for example, by the OEM and may not be reconfigurable by the end user.

[0105] In step 1406, user input is received via one or more user interfaces 1018 of the remote control device 150 to control the gas engine replacement device 10. For example, the user may actuate an input component on the remote control device 15. The electronic processor 1010 may determine the control action based on the received input (e.g., by retrieving data configured in a lookup table). The lookup table may be associated with a specific type of power equipment or gas engine replacement device 10 to which the remote control device 150 communicates, and may be selected from multiple lookup tables in memory 1020, for example, based on configuration information received in block 1404.

[0106] In step 1408, the electronic processor 1010 can transmit control signals to the gas engine replacement device 10 via the wireless interface 1020 or the wired interface 1022 based on the determined control action for operating the gas engine replacement device 10. In response to receiving the control signal, the electronic processor 302 of the gas engine replacement system 10 can initiate commands to turn on the motor 36, turn off the motor 36, change the speed of the motor 36, control the rotation direction of the motor 36 in the forward or reverse direction, or the accessory 154 (e.g., turn on, turn off, or adjust operating parameters).

[0107] In some embodiments, the remote control device 150 receives information about the status or condition of the gas engine replacement system 10 from the gas engine replacement system 10 via a wireless interface 1020 or a wired interface 1022. The electronic processor 1010 may transmit signals to one or more user interfaces 1018 to indicate the status or condition. For example, one or more user interfaces 1018 may indicate: the charge level of the battery pack 50, the remaining operating time of the battery pack 50, the duty cycle applied to the motor 36, the speed of the motor 36 or the power take-off shaft 38, the torque applied to the motor 36, the efficiency of the motor 36, or the condition of the accessory 154 (e.g., on / off or values ​​of operating parameters).

[0108] Figure 15This is a perspective view of pump system 1520, which is attached to gas engine replacement device 10 and controlled by remote control device 150. Pump system 1520 includes a frame 1524 supporting gas engine replacement device 10 and pump 1528, wherein gas engine replacement device 10 is operable to drive pump 1528. The pump 1528 shown (i.e., the power unit) is a centrifugal pump having an impeller positioned within a housing 1532 of pump 1528, which is rotatable about an axis to move material from inlet 1536 of pump 1528 to outlet 1540 of pump 1528. Specifically, pump 1528 is an "impurity pump" that includes a sufficient clearance (e.g., 8 mm) between the impeller of pump 1528 and housing 1532 to allow a mixture of liquid (e.g., water) and debris (e.g., solid materials, such as mud, pebbles, soil, sand, sludge, etc.) to pass through pump 1528 from inlet 1536 to outlet 1540, without the debris being trapped inside pump 1528 and degrading the performance of pump system 1520.

[0109] Typically, gas engine pumps only include one operating mode. Specifically, a gas engine may cause the motor to rotate only in one direction, limiting the pump's functionality. In contrast, pump system 1520 includes a gas engine replacement device 10 comprising a motor 36 that can rotate in both forward and reverse directions. Therefore, pump system 1520 is adapted to perform different functions based on the rotation direction of motor 36. When electronic processor 302 causes motor 36 to rotate in the first direction, pump 1528 can drive the impeller in the forward direction to move material from inlet 1536 of pump 1528 to outlet 1540 of pump 1528. When electronic processor 302 causes motor 36 to rotate in a second direction (e.g., as in block 420), pump 1528 can drive the impeller to clear blockages or clean pump 1528 if debris is stuck inside (without using a gearbox including forward and reverse gears). In some embodiments, the motor 36 may be controlled by an electronic processor 302 to rotate in a second direction at a slower speed than in a first direction to clear blockages in the pump 1528. For example, the electronic processor 302 may provide a PWM signal to the FET of the power switching network 310 with a higher duty cycle when driven in the first direction than when driven in the second direction, so that the motor 36 rotates in the first direction at a higher speed than in the second direction.

[0110] The pump includes sensors 1541 and 1542. Sensor 1541 detects the amount of liquid moving through pump 1528. Based on the output from sensor 1541, a signal can be sent to remote control device 150 for displaying an indication of the amount of liquid moving through pump 1528 via one or more user interfaces in user interface 1018. Based on input received via one or more user interfaces 1018, a signal is transmitted by electronic processor 1010 to electronic processor 302 of gas engine replacement device 10 to enable or disable operation of pump 1528 (e.g., drive motor 36). For example, display 1018 may indicate that the liquid level is at or above a threshold level or below a threshold level, and if the liquid level is below the threshold level, the user can actuate the user interface 1018 input to stop operation of pump 1528. However, in other embodiments, electronic processor 302 may simply monitor the current drawn by motor 36 to determine whether to slow down or stop motor 36.

[0111] A sensor 1542 on pump 1528 is connected to electronic processor 302 via a power equipment interface (not shown) and is arranged in the impeller reservoir of pump 1528. Sensor 1542 monitors the suction or fluid level in the impeller reservoir. Electronic processor 302 receives the output from sensor 1542 and transmits an indicator signal to remote control device 150 via wireless interface 1020 or wired interface 1022. In response, when the output of sensor 1542 indicates that pump 1528 is not adequately started, electronic processor 1010 may output a signal to an indicator (e.g., an LED or display device) on user interface 1018. In some embodiments, electronic processor 1010 may receive user input via one or more user interfaces 1018 and may transmit a signal to electronic processor 302 of gas engine replacement device 10 based on the user input to shut down pump 1528 to protect pump system 1520. Alternatively or additionally, based on user input, the electronic processor 302 can transmit a signal to the electrically controlled valve 1543 on the pump 1528 to adjust the discharge opening to support automatic start-up capability, thereby protecting the pump system 1520.

[0112] The gas engine replacement device 10 can be connected to and driven by other types of power equipment, such as compactors, tampers, injectors, and pump systems.
