[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0036] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise clearly and specifically defined.

[0038] When the fuel generator is used with a mobile energy storage device or other electronic equipment, they usually communicate through a wired connection. The corresponding communication signal is communicated through the hardware handshake through the connection line to determine whether the connection line between the fuel generator and the mobile energy storage device is successfully connected. After the connection is successful, the corresponding software communication and control are carried out.

[0039] However, if the communication line handshake is not set up, it will be impossible to determine whether the power circuit is abnormally connected simply through wireless connection. When the mobile energy storage device is out of power, a power generation request is sent to the fuel generator wirelessly, and the fuel generator starts to generate electricity after receiving the power generation request wirelessly. If the fuel generator and the mobile energy storage device have not completed the power line connection at this time, the fuel generator may be mistakenly started or idle, resulting in energy waste and safety risks.

[0040] In view of the above technical problems, some embodiments of the present application provide an improved power generation device, please refer to Figure 1The power generation device 100 includes an interface module 110 , a power generation module 120 , a battery module 130 , a power module 140 , a control module 150 and a communication module 160 .

[0041] The interface module 110 is used to establish an electrical connection with the power-consuming device 200. The power module 140 is connected to the power generation module 120, the battery module 130, the control module 150 and the communication module 160. The power module 140 is used to provide a starting voltage to the power generation module 120 based on the power of the battery module 130, and output power supply energy to the power interface based on the generated power output by the power generation module 120. The power generation module 120 is connected to the control module 150, and is used to start under the drive of the starting voltage to output the generated power.

[0042] The control module 150 is connected to the communication module 160. The control module 150 is used to receive a handshake signal through the communication module 160, and control the power module 140 to output a detection electrical signal to the interface module 110 based on the power of the battery module 130 according to the handshake signal, and receive a power generation request through the communication module 160. The power generation request is generated based on the detection electrical signal after the power consumption device 200 establishes a power connection with the power generation device 100.

[0043] The interface module 110 is, for example, an AC three-wire interface. The interface module 110 is electrically connected to the power-consuming device 200 by, for example, a cable connection or a gold finger plug connection. The communication module 160 is, for example, a wireless communication module. The power generation module 120 is, for example, a fuel generator set. The battery module 130 serves as a starting power source for the power generation module 120. The power-consuming device 200 is, for example, an energy storage device or other electronic device.

[0044] When the control module 150 receives the handshake signal through the communication module 160, the multiplexing power module 140 generates a detection electrical signal based on the battery module 130. The detection electrical signal is transmitted to the power-consuming device 200 through the interface module 110 in the form of power transmission. After receiving the power generation request generated based on the detection electrical signal after the power-consuming device 200 establishes a power connection with the power generating device 100, the control module 150 determines that the power connection between the power generating device 100 and the power-consuming device 200 is normal. When the control module 150 does not receive the power generation request, it is determined that the power connection between the power generating device 100 and the power-consuming device 200 is abnormal, that is, the handshake is determined to have failed. This handshake detection method uses the power generating device 100's own circuit to provide the interface module 110 with a detection electrical signal, does not require a separate communication line, and saves hardware costs.

[0045] See also Figure 2 The power module 140 includes a rectifying unit 141 , a DC-DC unit 142 , a first DC-AC unit 143 and a second DC-AC unit 144 .

[0046] The input end of the rectifier unit 141 is connected to the power generation module 120 , and the output end of the rectifier unit 141 is connected to the DC bus 145 , which is used to rectify the generated electric energy output by the power generation module 120 and output the generated DC power.

[0047] Exemplarily, the rectifier unit 141 may be a three-phase rectifier bridge, such as a three-phase half-controlled rectifier circuit, see Figure 4 The rectifying element of the rectifying unit 141 includes, for example, one or more types of diodes, thyristors, and IGBTs.

[0048] An input end of the DC-DC unit 142 is connected to the battery module 130 , and an output end of the DC-DC unit 142 is connected to the DC bus 145 , for outputting direct current to the DC bus 145 based on the power of the battery module 130 .

[0049] Exemplarily, the DC-DC unit 142 is, for example, a non-isolated boost circuit, see Figure 4 Generally, the DC-DC unit 142 is used to provide a starting voltage for the power generation module 120 based on the battery module 130. In the technical solution of the embodiment of the present application, it is also used to provide a detection electrical signal when performing a handshake detection with the power-consuming device 200 based on the battery module 130.

[0050] The input end of the first DC-AC unit 143 is connected to the DC bus 145 , and the output end of the first DC-AC unit 143 is connected to the power generation module 120 , for generating a starting voltage based on the DC power on the DC bus 145 and outputting it to the power generation module 120 .

[0051] Exemplarily, the first DC-AC unit 143 may be a three-phase H-bridge circuit, see Figure 4 The DC side of the first DC-AC unit 143 is connected to the DC bus 145, and the AC side is connected to the power generation device 100. The first DC-AC unit 143 is a boost converter, a buck converter, or a buck-boost converter.

[0052] The input end of the second DC-AC unit 144 is connected to the DC bus 145, and the output end of the second DC-AC unit 144 is connected to the interface module 110, and is used to generate a detection electrical signal based on the DC power on the DC bus 145, or to generate power supply energy based on the DC power on the DC bus 145. The voltage of the detection electrical signal is less than the voltage of the power supply energy.

[0053] Exemplarily, the second DC-AC unit 144 includes an inverter full-bridge circuit 1441 and an LC resonator 1442 connected in sequence between the DC bus 145 and the interface module 110, see Figure 4 .

[0054] In some embodiments, the control module 150 includes a first control unit 151 and a second control unit 152 that communicate with each other. The rectifier unit 141 and the first DC-AC unit 143 are controlled by the first control unit 151, and the DC-DC unit 142 and the second DC-AC unit 144 are controlled by the second control unit 152. In other embodiments, the aforementioned units may be controlled by the same control unit.

[0055] In some embodiments, the DC-DC unit 142 is used to achieve a reverse drag effect. The reverse drag effect means that the voltage of the battery module 130 outputs a starting voltage through the DC-DC unit 142 and the first DC-AC unit 143 to enable the power generation module 120 to generate electricity. That is, the original current transmission path of the power module 140 only has path 1: DC-DC unit 142-DC bus 145-first DC-AC unit 143-power generation module 120, and path 2: power generation module 120-rectifier unit 141-DC bus 145-second DC-AC unit 144-interface module 110. The technical solution of the embodiment of the present application adds path 3: DC-DC unit 142-DC bus 145-second DC-AC unit 144-interface module 110 on the basis of reusing the original circuit, without adding a new device.

[0056] The detection electrical signal includes a PWM signal or a constant voltage signal. When the detection electrical signal is a constant voltage signal, considering the circuit loss, the power-consuming device 200 can determine that the handshake is successful when detecting a voltage within a preset range, and send a power generation request to the power generation device 100.

[0057] In one embodiment, the voltage value of the detected electrical signal is lower than the voltage value of the power supply energy to prevent the powered device 200 from misjudging the device as transmitting power or causing damage.

[0058] In one embodiment, the communication module 160 includes a Bluetooth unit and / or a WIFI unit, and communicates with the power-consuming device 200 via Bluetooth or WIFI, thereby saving the cost of communication cables.

[0059] See also Figure 3 In one embodiment, the power generation device 100 further includes an auxiliary power module 170, which is connected to the battery module 130 and the control module 150. The auxiliary power module 170 is used to generate a working voltage based on the power of the battery module 130 to supply power to the control module 150. Exemplarily, the auxiliary power module 170 is constructed based on a flyback circuit, and supplies power to each unit, drive circuit / chip through a plurality of low dropout linear regulator (LDO) circuits, see Figure 4 .

[0060] See also Figure 3In one embodiment, the power generation device 100 further includes a starting module 180, which is connected between the output end of the first DC-AC unit 143 and the power generation module 120. The starting module 180 is also connected to the control module 150, and the control module 150 is further used to control the starting module 180 to connect the connection between the first DC-AC unit 143 and the power generation module 120 based on the power generation request, so that the power generation module 120 obtains the starting voltage to start.

[0061] For example, see Figure 4 The start module 180 includes three controllable switches K1, K2, and K3, which are respectively connected to the three-phase line connected to the output end of the first DC-AC unit 143 and the power generation module 120. The controllable switches are, for example, relays and contactors.

[0062] Figure 4 The specific schematic diagram of the power generation device provided by the embodiment of the present application is shown. In the power generation device 100, the first control unit 151 samples the phase voltage and the phase current of the output end of the power generation module 120 through the phase voltage sampling circuit 191 and the phase current sampling circuit 192. The first control unit 151 also enables the three controllable switches K1, K2, and K3 of the start module 180 through the enabling circuit 193. The first control unit 151 also drives the first DC-AC unit 143 and the rectifier unit 141 through the driving circuits 194 and 195 respectively. The second control unit 152 samples the bus voltage and bus current of the DC bus 145 through the bus sampling circuit 196. The second control unit 152 also samples the transmission voltage and transmission current of the interface module 110 through the AC voltage sampling circuit 197 and the AC current sampling circuit 198. The second control unit 152 also drives the second DC-AC unit 144 and the DC-DC unit 142 through the driving circuits 199A and 199B respectively.

[0063] Combination Figure 4 , the power generation device 100 is described in detail from handshake to power generation. The power generation device 100 and the power consumption device 200 are connected through Bluetooth or WiFi of the communication module 160. The operator can use a mobile terminal to connect to the power consumption device 200 through Bluetooth or WiFi, and then use the mobile terminal to control the power consumption device 200 and the power generation device 100. When the power consumption device 200 has a power demand, it sends a handshake signal to the power generation device 100 through Bluetooth or WiFi.

[0064] Handshake stage: The communication module 160 in the power generation device 100 receives the handshake signal and forwards the handshake signal to the second control unit 152. The second control unit 152 drives the DC-DC unit 142 through the drive circuit 199B to boost the voltage output by the battery module 130 to 20V DC and output it to the DC bus 145. At the same time, the second control unit 152 drives the second DC-AC unit 144 through the drive circuit 199A to invert the 20V DC on the DC bus 145, and then outputs 12V AC (i.e., the detection electrical signal) to the power-consuming device 200 through the interface module 110. When the power-consuming device 200 samples this 12V AC, it determines that the hardware handshake with the power generation device 100 is successful. The power-consuming device 200 sends a request to the power generation device 100 to start the power generation of the power generation device 100 through Bluetooth or WiFi, and stops automatically until the power demand ends.

[0065] Startup phase: The communication module 160 in the power generation device 100 receives the power generation request and forwards the power generation request to the second control unit 152, which is also forwarded to the first control unit 151 by the second control unit 152. In response to the power generation request, the second control unit 152 drives the DC-DC unit 142 through the drive circuit 199B to boost the voltage output by the battery module 130 to 20V DC and output it to the DC bus 145. At the same time, the first control unit 151 drives the first DC-AC unit 143 through the drive circuit 194 to invert the 20V DC on the DC bus 145 to obtain the startup voltage. The first control unit 151 also enables the startup module 180 through the enable circuit 193 to output the startup voltage to the power generation module 120. The power generation module 120 starts under the drive of the startup voltage and outputs the generated electric energy to the rectifier unit 141.

[0066] Power generation stage: After the power generation module 120 is started, the first control unit 151 stops driving the drive circuit 194 and stops enabling the enabling circuit 193 to shut down the first DC-AC unit 143 and the startup module 180. The first control unit 151 drives the rectifier unit 141 through the drive circuit 195 to rectify the generated power output by the power generation module 120, and outputs the generated direct current to the DC bus 145. At the same time, the second control unit 152 stops the drive circuit 199B to shut down the DC-DC unit 142, and drives the second DC-AC unit 144 through the drive circuit 199A to generate power supply power from the direct current on the DC bus 145, and outputs it from the interface module 110 to the power-consuming device 200.

[0067] Compared with the traditional technical solution, the technical solution provided in the embodiment of the present application first establishes communication, and then starts to execute handshake detection according to whether the power-consuming device 200 has power demand. The power generation device 100 provided in the embodiment of the present application receives the handshake signal through the communication module 160, and the multiplexing power module 140 generates a detection electrical signal based on the battery module 130 and transmits it to the power-consuming device 200 through the interface module 110. After receiving the power generation request generated by the power-consuming device 200 based on the detection electrical signal after establishing a power connection between the power generation device 100 and the power generation device 100 through the communication module 160, the power generation device 100 determines that the power connection line is connected normally. When the power generation device 100 does not receive the power generation request, it determines that the power connection line fails, that is, the handshake fails. The power generation device 100 provided in the embodiment of the present application does not require a separate communication line for handshake detection with the power-consuming device 200, saving hardware costs.

[0068] See also Figure 5 An embodiment of the present application further provides a method for starting a power generation device as described in any of the above embodiments, the method comprising:

[0069] Step S110, obtaining a handshake signal.

[0070] Step S120 , controlling the power module to generate a detection electrical signal based on the electrical energy of the battery module according to the handshake signal.

[0071] Step S130 , when a power generation request is obtained, the power module is controlled to generate a starting voltage to the power generation module based on the electric energy of the battery module, so as to start the power generation module.

[0072] In one example, the power generation device 100 and the power consumption device 200 are connected via Bluetooth or WiFi. In some embodiments, the operator can use a mobile terminal to connect to the power consumption device 200 via Bluetooth or WiFi, and then use the mobile terminal to control the power consumption device 200 and the power generation device 100. When the power consumption device 200 has a power demand, it sends a handshake signal to the power generation device 100 via Bluetooth or WiFi.

[0073] Specifically: the control module 150 in the power generation device 100 drives the DC-DC unit 142 and the second DC-AC unit 144, and controls the second DC-AC unit 144 to output a preset detection electrical signal (e.g., AC voltage), which is output to the power consumption device 200 through the interface module 110. In the embodiment of the present application, the voltage of the detection electrical signal output by the second DC-AC unit 144 is much lower than the voltage of the normal power generation output of the power generation device 100. For example, the voltage of the detection electrical signal can be 12V AC, and the DC-DC unit 142 can boost the voltage output by the battery module 130 to 20V DC and output it to the DC bus 145. After the second DC-AC unit 144 inverts the 20V DC on the DC bus 145, it outputs 12V AC to the power consumption device 200 through the interface module 110. When the power consumption device 200 samples the 12V AC, it determines that the hardware handshake with the power generation device 100 is successful. The power-consuming device 200 sends a request to start the power generation device 100, and then stops automatically when the power demand ends.

[0074] The traditional technical solution first determines whether the handshake is successful by wired connection, then determines whether the software communication is successful, and then performs control. Compared with the traditional technical solution, the technical solution provided in the embodiment of the present application first establishes communication, and then starts to execute the handshake detection based on whether the power-consuming device 200 has power demand. During the handshake detection, only the DC-DC unit 142 and the second DC-AC unit 144 of the power generation equipment 100 are working, and the output detection electrical signal voltage is low, and the output detection electrical signal is given to the power-consuming device 200 for judgment. When the power-consuming device 200 detects the detection electrical signal, it is determined that the power connection is normal. When the power-consuming device 200 does not receive the detection electrical signal, it is determined that the power connection is abnormal and the handshake fails.

[0075] See also Figure 6 In one embodiment, the method for starting the power generation equipment further comprises:

[0076] Step S210, obtaining the target output power in the power generation request.

[0077] Combination Figures 1 to 5 After the power generation module 120 is started, the control module 150 will control the power module 140 to work according to the request of the power consumption device 200 according to the target output power in the power generation request.

[0078] Step S220, determining a target bus voltage of the DC bus according to the target generated power.

[0079] The control module 150 determines the target bus voltage according to the target power generation, the voltage conversion capability of the rectifier unit 141 and the second DC-AC unit 144 in the power module 140 .

[0080] Step S230, controlling the power module to increase the bus voltage of the DC bus to the target bus voltage, and when it is determined that the bus voltage of the DC bus reaches the target bus voltage, controlling the power module to output the target output power.

[0081] Among them, the first control unit 151 of the control module 150 drives the rectifier unit 141 to rectify the generated electric energy of the power generation module 120, and charges the bus capacitor of the DC bus 145, so that the bus voltage rises to the target bus voltage. In response to the bus voltage rising to the target bus voltage, the second control unit 152 drives the second DC-AC unit 144 to convert the voltage of the DC power on the DC bus 145, outputs the target output power to the power-consuming device 200, and completes the power supply to the power-consuming device 200.

[0082] For the specific implementation of the method for starting the power generation equipment and the description of the related beneficial effects, please refer to the description of the specific embodiment of the power generation equipment 100 mentioned above, which will not be repeated here.
