DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] Existing electric devices such as new energy vehicles usually need to be charged by external charging guns when parked, and reversely inverted or output AC power to the outside through a DC discharge inverter. When the electric device is used to power external devices, the operation is cumbersome and it cannot be powered while driving. In addition, the off-board inverter function of the existing electric device does not distribute power. When the electric device is connected to the external device, it directly inverts and supplies power to the outside. If the power used by the external device exceeds the rated power of the on-board charger (OBC), the inverter control system automatically stops the inverter output, resulting in a decrease in the practicality of the inverter power supply of the electric device, which cannot meet the customer's usage needs in complex power usage scenarios.

[0029] In view of this, the embodiment of the present application proposes an inverter control system, which is applied to an electric device, including but not limited to new energy vehicles. The electric device includes at least one power supply circuit and a control component. The power supply circuit is a circuit element that outputs electric energy of a preset power to an external device through an interface device. The interface device is not limited to a socket, a plug, a jack, a wiring board, and other devices for connecting a power source and an external electrical appliance.

[0030] See also Figure 1 , Figure 1 Schematic diagram of the structure of the first embodiment of the inverter control system provided by the present application. Figure 1As shown, the electrical device used in the inverter control system 10 of this embodiment includes at least one power supply circuit 41 and a control component 42.

[0031] The inverter control system 10 includes a power distribution circuit 11 and a control circuit 21. The power distribution circuit 11 is connected to the power supply circuit 41 to control the power supply circuit of the power supply circuit 41 and generate a switch signal when the switch circuit 410 is triggered; the control circuit 21 is connected to the power distribution circuit 11 and the control component 42 respectively, and the control circuit 21 receives the switch signal from the power distribution circuit 11. Among them, the power distribution circuit 11 is responsible for the power distribution and management in the power consumption device to control the charging and discharging process, power-on control, etc. of the power consumption device. The power distribution circuit 11 is connected to the power supply circuit 41 to control the opening or closing of the power supply circuit of the power supply circuit 41. When the user needs to provide power to the external device through the power consumption device, the power cord plug of the external device can usually be in contact with the socket of the power consumption device. The switch circuit 410 is usually set in the socket to trigger the switch circuit 410 when the user plugs in the plug. When the switch circuit 410 is triggered, the power distribution circuit 11 is used to generate a switch signal and transmit the switch signal to the control circuit 21.

[0032] The control circuit 21 is used to control the control component 42 to generate an interactive interface based on the switch signal. The interactive interface can be a visual interface displayed on the visual screen of the control component 42. The interactive interface is used to display the power consumption related data or information of the power supply circuit 41, so that the user can confirm the power consumption of the power supply circuit 41. When the user confirms the discharge of at least one power supply circuit 41 through the interactive interface, the interactive interface generates confirmation information and sends the confirmation information to the control circuit 21. The control circuit 21 receives the confirmation information from the interactive interface, and the control circuit 21 is also used to control the power distribution circuit 11 to close the power supply loop based on the confirmation information, so that the power supply circuit 41 outputs electric energy of a preset power.

[0033] In an embodiment of the present application, the inverter control system 10 includes a power distribution circuit 11 and a control circuit 21; the power distribution circuit 11 is connected to the power supply circuit 41, and is used to control the power supply circuit of the power supply circuit 41, and generate a switching signal when the switch circuit 410 is triggered; the control circuit 21 is respectively connected to the power distribution circuit 11 and the control component 42, and the control circuit 21 receives the switching signal from the power distribution circuit 11; the control circuit 21 is used to control the control component 42 to generate an interactive interface based on the switching signal, so as to receive confirmation information from the interactive interface, and the control circuit 21 is also used to control the power distribution circuit 11 to close the power supply circuit based on the confirmation information, so that the power supply circuit 41 outputs electrical energy of a preset power. In the above manner, the inverter control system 10 can jointly control the external discharge of the power supply circuit 41 through the triggering of the switch circuit 410 and the confirmation of the interactive interface, so as to reduce the false triggering of the power supply circuit 41 and the like; and, after the interactive interface confirms the power supply, the inverter system controls the power distribution circuit 11 to close the power supply loop through the control circuit 21, so that the power distribution circuit 11 can output electric energy of a preset power without affecting other functions of the electrical device, and the electrical device can be used in different scenarios to discharge the power through the power distribution circuit 11, thereby improving the practicality of the electrical device.

[0034] In one embodiment, see Figure 2 , Figure 2 Schematic diagram of the structure of the second embodiment of the inverter control system provided by the present application. Figure 2 As shown, the control circuit 21 includes a vehicle controller 210 and a battery manager 220. The vehicle controller 210 is connected to the power distribution circuit 11 and the battery manager 220 respectively. The battery manager 220 is connected to the control component 42. The battery manager 220 is used to receive the confirmation information returned by the control component 42, so as to send a first inverter request to the vehicle controller 210 based on the confirmation information. The vehicle controller 210 is used to obtain the status information of the power-consuming device based on the first inverter request, so as to control the power distribution circuit 11 to close the power supply circuit when the status information meets the preset discharge condition.

[0035] Specifically, the control circuit 21 is used to control the electric energy working process of the electric device. When the electric device is a new energy vehicle or other device, the control circuit 21 may include a vehicle controller 210 and a battery manager 220. The vehicle controller 210 (Vehicle control unit, VCU) is responsible for the power control, energy control, and coordination between various systems of the vehicle, and the battery manager 220 (Battery Management System, BMS) is used to monitor and manage the energy storage of the battery to ensure the safe use of the electric device during the charging and discharging process.

[0036] The vehicle controller 210 is connected to the power distribution circuit 11 and the battery manager 220 respectively, and the battery manager 220 is connected to the control component 42. The control component 42 is used to generate confirmation information after the user confirms the discharge through the interactive interface, and send the confirmation information to the battery manager 220; the battery manager 220 is used to send a first inversion request to the vehicle controller 210 based on the confirmation information after receiving the confirmation information. The vehicle controller 210 is used to obtain the status information of the power-consuming device based on the first inversion request, so as to control the power distribution circuit 11 to close the power supply circuit when the status information meets the preset discharge condition.

[0037] Among them, the first inversion request is used to instruct the control component 42 to confirm that the power supply circuit 41 performs a discharge operation, and the first inversion request includes but is not limited to the power data or power range when the power supply circuit 41 performs a discharge operation. The vehicle controller 210 can determine whether the state information of the power-consuming device meets the power demand of the power supply circuit 41 based on the power data or power range of the first inversion request, so as to control the power distribution circuit 11 to close the power supply loop when the state information meets the preset discharge condition. In a possible implementation, the power distribution circuit 11 may include an in-vehicle inverter control branch, the in-vehicle inverter control branch is connected to the power supply circuit 41, and the in-vehicle inverter control branch is used to power the power supply circuit 41 through the in-vehicle inverter discharge, so that the power supply circuit 41 outputs electric energy of a preset power; the vehicle controller 210 is used to control the power distribution circuit 11 to close the in-vehicle inverter control branch when the state information meets the preset discharge condition. The in-vehicle inverter control branch includes but is not limited to being connected to the power supply circuit 41 through a relay, and the power distribution circuit 11 can be closed by controlling the relay to close the power supply loop.

[0038] Through the above-mentioned method, the inverter control system 10 of this embodiment can send a first inverter request to the vehicle controller 210 through the battery manager 220, and the vehicle controller 210 is used to obtain the status information of the power-consuming device based on the first inverter request, so as to control the power distribution circuit 11 to close the power supply circuit when the status information meets the preset discharge condition; when the power-consuming device is a new energy vehicle, the inverter control system 10 can close the power supply circuit through the in-vehicle inverter control power distribution circuit 11 during the driving of the vehicle, perform in-vehicle inverter when the status information of the vehicle meets the discharge condition, and supply power to external devices through the power supply circuit 41 without affecting other main functions of the power-consuming device such as driving, thereby enabling the power-consuming device to be used in different scenarios to discharge to the outside through the power distribution circuit 11, thereby improving the practicality of the power-consuming device.

[0039] Optionally, the vehicle controller 210 is further configured to send a second inversion request to the battery manager 220 when the state information meets the discharge condition. The inverter control system 10 further includes an electric control circuit 31, which is connected to the battery manager 220 and the power distribution circuit 11 respectively. The battery manager 220 is further configured to send inversion discharge data to the electric control circuit 31 based on the second inversion request, and the electric control circuit 31 is configured to adjust the discharge power of the power distribution circuit 11 based on the inversion discharge data.

[0040] Specifically, the vehicle controller 210 is also used to send a second inversion request to the battery manager 220 when the status information meets the discharge condition. The second inversion request is used to indicate that the current power-consuming device can meet the discharge operation of the power supply circuit 41 and allow the inversion discharge of the power supply circuit 41. After receiving the second inversion request, the battery manager 220 sends a third inversion request and the inversion discharge data of the power supply circuit 41 to the electric control circuit 31 based on the second inversion request. The inversion discharge data may include relevant working data when the power supply circuit 41 is allowed to discharge. The electric control circuit 31 is used to start the inversion output of the power distribution circuit 11 after receiving the third inversion request, and adjust the discharge power of the power distribution circuit 11 based on the inversion discharge data to provide the power supply circuit 41 with electrical energy of a preset power.

[0041] In the embodiment of the present application, the vehicle controller 210 sends a second inversion request to the battery manager 220 when the state information meets the discharge condition. The battery manager 220 sends the inversion discharge data to the electric control circuit 31 based on the second inversion request. The electric control circuit 31 adjusts the discharge power of the power distribution circuit 11 based on the inversion discharge data to ensure that the power supply circuit 41 can output the electric energy of the preset power. Since the power supply circuit 41 is connected to the electric control circuit 31 through the power distribution circuit 11, when the electric device is a new energy vehicle, the inverter control system 10 can close the power supply circuit through the in-vehicle inverter control power distribution circuit 11 during the driving of the vehicle without affecting other main functions of the electric device such as driving, thereby enabling the electric device to be used in different scenarios to discharge externally through the power distribution circuit 11, thereby improving the practicality of the electric device.

[0042] For further information, see Figure 3 , Figure 3 is a schematic diagram of the structure of the third embodiment of the inverter control system provided by the present application. Figure 3 As shown, the electric control circuit 31 includes a power distributor 310 and an inverter 320. The power distributor 310 is connected to the battery manager 220. The inverter 320 is respectively connected to the power distributor 310 and the power distribution circuit 11. The inverter 320 is used to output alternating current. The power distributor 310 is used to receive inverter discharge data and control the inverter output of the inverter 320 based on the discharge power of the inverter discharge data.

[0043] Specifically, the inverter 320 includes but is not limited to a DC-DC converter, an AC-DC converter, etc., and the electric control circuit 31 can be but is not limited to a high-voltage electric control system solution circuit, which integrates functions such as an on-board charger (OBC), an inverter 320, and a high-voltage distribution box. The electric control circuit 31 is used to convert the electric energy of an external power source to charge the battery of an electrical device; the electric control circuit 31 can also be used to invert and discharge the electric energy of the battery to provide the power supply circuit 41 with electric energy of a preset power. The inverter 320 is used to output alternating current to provide the power supply circuit 41 with alternating current of a preset power through the power distribution circuit 11. The power distributor 310 is connected to the battery circuit controller and the inverter 320 respectively, and the power distributor 310 is used to control the inverter output of the inverter 320.

[0044] After the power distributor 310 receives the third inversion request and the inversion discharge data from the battery manager 220, the power distributor 310 is used to control the inversion output of the inverter 320 based on the allowable discharge power of the inversion discharge data, so as to adjust the discharge power of the power distribution circuit 11, so that the power supply circuit 41 can output electric energy of the preset power. Among them, the inversion discharge data is the relevant working data when the power supply circuit 41 is allowed to discharge. According to the inversion discharge data of the power supply circuit 41, the power distributor 310 can calculate or obtain the relevant parameters of the alternating current when the inverter 320 performs inversion output corresponding to the inversion discharge data. Exemplarily, the inversion discharge data may include the allowable discharge power or working power of the power supply circuit of the power supply circuit 41. The power distributor 310 can calculate or obtain the inversion parameters of the inverter 320 based on the allowable discharge power or working power of the inversion discharge data, so that the power distributor 310 controls the inverter 320 to perform inversion output with the inversion parameters corresponding to the inversion discharge data, so as to ensure the stability and accuracy of the inversion output of the inverter 320.

[0045] In a possible implementation, the power distribution circuit 11 includes an in-vehicle inverter control branch, and the output end of the inverter 320 is connected to the power supply circuit 41 through the in-vehicle inverter control branch of the power distribution circuit 11, so that the power distributor 310 controls the inverter output of the inverter 320, and then controls the output discharge of the power supply circuit 41, thereby ensuring that the power supply circuit 41 outputs electrical energy of a preset power.

[0046] In the embodiment of the present application, the inverter 320 outputs AC power, the power distributor 310 is used to receive the inverter discharge data, and control the inverter output of the inverter 320 based on the allowed discharge power, and the discharge power of the inverter 320 corresponds to the preset power of the power supply circuit 41 to ensure the stable output of the power supply circuit 41. Since the power distribution circuit 11 is connected to the power distributor 310, the power distribution circuit 11 can call the in-vehicle inverter function of the inverter 320 to output electric energy during the driving power consumption of the electric device, so that after the power supply loop is closed, the power distribution circuit 11 can output the preset power of electric energy to the power supply circuit 41. The user can call the electric energy of the power supply circuit 41 through the in-vehicle inverter during the driving of the car to charge external devices, thereby improving the applicability of the electric device in different scenarios and improving the practicality of the electric device.

[0047] Still further, the power distributor 310 is used to set an overcurrent protection threshold of the inverter 320 based on the inverter discharge data, so as to cut off the output of the inverter 320 when the inverter power of the inverter 320 exceeds the overcurrent protection threshold.

[0048] Specifically, the inverter discharge data is the relevant working data when the power supply circuit 41 is allowed to discharge. The power distributor 310 can calculate or obtain the inverter parameters of the inverter 320 corresponding to the inverter discharge data when the inverter outputs based on the inverter discharge data of the power supply circuit 41, and the overcurrent protection threshold of the inverter 320 can be set according to the power demand corresponding to the inverter parameter. The overcurrent protection threshold is usually set to be slightly higher than the inverter power of the inverter 320 to ensure that the power distributor 310 can respond in time when the load power of the power supply circuit 41 changes or short circuits or other abnormal conditions occur. The power distributor 310 cuts off the output of the inverter 320 when the inverter power of the inverter 320 exceeds the overcurrent protection threshold to protect the power supply circuit 41 and improve the power safety of the electrical device.

[0049] Optionally, the inverter control system 10 further includes a fault detection circuit, the vehicle controller 210 is connected to the fault detection circuit, and the vehicle controller 210 is used to obtain status information based on the fault record of the fault detection circuit.

[0050] Specifically, the fault detection circuit of the inverter control system 10 can be used to perform fault detection on the entire vehicle part of the electrical device. The detection scope of the fault detection circuit includes but is not limited to: detecting whether there is a fault in the entire vehicle sensor of the electrical device, whether the high-voltage system is normal, whether the battery manager 220 is normal, whether the electronic control circuit 31 is normal, etc.

[0051] The vehicle controller 210 obtains the status information of the electrical device by acquiring the fault record of the fault detection circuit. When the status information does not meet the preset discharge condition, that is, the detection record of the fault detection circuit indicates that the vehicle part of the electrical device is faulty, for example, at least one part in the above detection range is faulty and cannot meet the in-vehicle inversion condition of the inverter 320, the vehicle controller 210 can send a rejection request for inversion to the battery manager 220, and the battery manager 220 is used to forward the rejection request for inversion to the control component 42, so that the fault information record, status information and at least one information of the rejection request for inversion of the electrical device are displayed on the interactive interface of the control component 42, so that the user can view the inversion process of the inverter 320, the working status of the power supply circuit, etc. through the interactive interface, thereby improving the user's experience.

[0052] When the status information meets the preset discharge conditions, that is, the detection record of the fault detection circuit indicates that there is no abnormality in the vehicle part of the electrical device, the electrical device can support the in-vehicle inversion of the inverter 320. The vehicle controller 210 is used to control the power distribution circuit 11 to close the power supply loop to provide the power supply circuit 41 with preset power through the in-vehicle inversion of the inverter 320.

[0053] Optionally, the control circuit 21 also includes a domain controller 230, which is connected to the power distribution circuit 11 and the battery manager 220 respectively. The domain controller 230 is used to receive status data of the switching circuit 410 from the power distribution circuit 11. The domain controller 230 is also used to forward the switching signal to the battery manager 220 when the status data includes the switching signal.

[0054] Specifically, the domain controller 230 may be a backend or an extension of a body control module (BCM). The domain controller 230 is used to provide a communication interface so that the power distribution circuit 11 and the battery manager 220 can achieve communication connection through the body controller to achieve information integration and coordination of the power-consuming devices. The domain controller 230 is used to receive the status data of the switch circuit 410 from the power distribution circuit 11, and the status data is used to indicate the triggering status of the switch circuit 410. When the status data includes a switch signal, it means that the switch circuit 410 is triggered. The domain controller 230 is also used to forward the switch signal to the battery manager 220, so that the battery manager 220 performs subsequent operations and realizes the power output of the power supply circuit 41.

[0055] In a possible implementation, the switch circuit 410 can be a switch with a small contact spacing. The switch circuit 410 is used to control the rapid connection or disconnection between the contacts when an external force acts on the transmission element, so as to ensure the precise control and rapid response of the switch circuit 410 and improve the accuracy and timeliness of the status data.

[0056] Optionally, see Figure 4 , Figure 4 is a schematic diagram of the structure of the fourth embodiment of the inverter control system provided by the present application. Figure 4 As shown, at least a first power supply circuit and a second power supply circuit are arranged inside the electrical device. The first power supply circuit is connected to the power distribution circuit 11 through a first loop, and the second power supply circuit is connected to the power distribution circuit 11 through a second loop. The power distribution circuit 11 is used to control the closure of the power supply circuit of the first power supply circuit and / or the second power supply circuit.

[0057] In one embodiment, the working powers of the first power supply circuit and the second power supply circuit are different. When the user triggers the switch circuit 410 corresponding to the first power supply circuit by plugging into the socket of the electrical device, the power distribution circuit 11 generates a switch signal so that the battery manager 220 controls the control component 42 to generate an interactive interface based on the switch signal. The battery manager 220 can be used to send a first inverter request to the vehicle controller 210 based on the confirmation information of the interactive interface, and the vehicle controller 210 is used to control the power distribution circuit 11 to close the power supply circuit of the first power supply circuit when the status information meets the preset discharge condition, so that the first power supply circuit outputs electrical energy matching its working power.

[0058] Among them, a power supply detection branch may be provided on the first power supply circuit, and the power supply detection branch is used to match the connection status of the external device connected to the first power supply circuit through the socket, so as to generate feedback information when the working power of the external device does not match that of the first power supply circuit, and the power distribution circuit 11 is used to forward the feedback information to the battery manager 220, and the battery manager 220 is used to control the control component 42 to display the feedback information on the interactive interface, so that the user can view and change the power operation. Exemplarily, the working power of the second power supply circuit can be higher than the working power of the first power supply circuit. When the feedback information of the first power supply circuit indicates that the working power of the external device connected to the socket exceeds the working power of the first power supply circuit, the interactive interface can be used to display relevant information that the working power of the external device does not match that of the first power supply circuit, and display the suggestion information suggesting that the user change the power operation to the second power supply circuit.

[0059] Through the above method, when the electrical device is a new energy vehicle, the user can select the corresponding power supply circuit for use in different power usage scenarios through the socket connected to the power supply circuit in the vehicle environment without affecting other main functions of the electrical device such as driving, thereby improving the user's convenience in electricity use and improving the practicality of the electrical device.

[0060] In another embodiment, the connection positions of the first power supply circuit and the second power supply circuit are different. Specifically, when the electric device is a new energy vehicle, the socket connected to the first power supply circuit and the socket connected to the second power supply circuit are located at different positions in the vehicle. Exemplarily, the socket of the first power supply circuit can be located in the front seat area of ​​the car, and the second power supply circuit can be located in the back seat area of ​​the car, so that the user can select the corresponding power supply circuit for use based on different usage scenarios without affecting other main functions of the electric device such as driving, thereby improving the convenience of electricity use for the user and the practicality of the electric device.

[0061] Different from the prior art, the inverter control system 10 of this embodiment sets a power supply circuit 41 in the vehicle, and sets a power distribution circuit 11, which is respectively connected to the power supply circuit 41 and the control circuit 21, so that the power supply circuit 41 can call the in-vehicle inverter function of the inverter 320 for discharge output, so that the user can use electricity through the power supply circuit 41 in situations such as vehicle driving, vehicle charging, and vehicle discharging to the load, thereby realizing the in-vehicle inverter function of the inverter control system 10 and improving the applicability of power-consuming devices in different scenarios; and the power distributor 310 sets an overcurrent protection threshold in the inverter 320 to protect the inverter 320 and the power supply circuit, which can effectively improve the power safety of the power supply circuit 41.

[0062] The present application also provides an inverter control method, which is applied to the inverter control system 10 of any of the above embodiments. Figure 5 , Figure 5 1 is a flow chart of an embodiment of the inverter control method provided by the present application. Figure 5 As shown, the inverter control method of this embodiment includes:

[0063] Step S11 : In response to the switch circuit 410 being triggered, a switch signal is generated.

[0064] Specifically, when the switch circuit 410 is triggered, a switch signal is generated, and the switch signal is used to indicate the triggering state of the switch circuit 410 .

[0065] Step S12: Based on the switch signal, the control component 42 is controlled to generate an interactive interface to receive confirmation information returned by the interactive interface.

[0066] After acquiring the switch signal, the control component 42 generates an interactive interface based on the switch signal to allow the user to confirm the power consumption of the power supply circuit 41. When the user confirms the discharge operation of the power supply circuit 41 connected to the switch circuit 410 through the interactive interface, the interactive interface generates confirmation information and returns the confirmation information.

[0067] Step S13: Based on the confirmation information, the power distribution circuit 11 is controlled to close the power supply loop of the power supply circuit 41 so that the power supply circuit 41 outputs electric energy of a preset power.

[0068] After obtaining the confirmation information, the power distribution circuit 11 is controlled based on the confirmation information to close the power supply loop of the power supply circuit 41 so that the power supply circuit 41 outputs electric energy of a preset power.

[0069] In the embodiment of the present application, the inverter control method generates a switch signal in response to the switch circuit 410 being triggered, controls the control component 42 to generate an interactive interface based on the switch signal, receives the confirmation information returned by the interactive interface, and controls the power distribution circuit 11 to close the power supply circuit of the power supply circuit 41 based on the confirmation information, so that the power supply circuit 41 outputs electric energy of a preset power. The inverter control method controls the closure of the power supply circuit through the triggering of the switch circuit 410 and the confirmation of the interactive interface to reduce the false triggering of the power supply circuit 41; and, after the interactive interface confirms the power supply, the inverter system controls the power distribution circuit 11 to close the power supply circuit through the control circuit 21, so that the power distribution circuit 11 can output electric energy of a preset power without affecting other functions of the electric device, and the electric device can be used in different scenarios to discharge to the outside through the power distribution circuit 11, thereby improving the practicality of the electric device.
