For some electrical appliances or tools that require AC power, inverter units are needed to convert the DC power output from the energy storage components into AC power.

[0003] However, most existing inverters are designed as stand-alone units with low intelligence, unable to monitor the real-time status of the vehicle, resulting in limited functionality. Summary of the Invention

[0067] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0068] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0069] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0070] Please refer to the following first. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a module of an embodiment of a smart inverter provided in this application. Figure 2 This is a schematic diagram illustrating an application scenario of an embodiment of the smart inverter provided in this application.

[0071] like Figure 1 and Figure 2 As shown, the intelligent inverter 100 can be used to invert and convert the power supply output from the vehicle's on-board battery 201 to obtain the target power supply, and then output the target power supply. The target power supply obtained by the intelligent inverter 100 can be used to supply power to the target load 300. As one embodiment, the power supply is a DC power supply, and the target power supply is an AC power supply.

[0072] It should be understood that the target load 300 is, for example, an appliance or tool that needs to operate under AC power. The power output of the vehicle battery 201 is generally in the form of DC power. The electrical energy stored in the vehicle battery 201 can not only provide power to the vehicle's own modules, but also provide power to various appliances and tools to ensure their normal operation when people are working or traveling. For the target load 300 that needs to operate under AC power, the intelligent inverter 100 can convert the DC power output from the energy storage component into the target AC power to supply power to the target load 300.

[0073] For example, the vehicle battery 201 includes a car battery, which can be a rechargeable battery or a supercapacitor.

[0074] Specifically, the intelligent inverter 100 provided in this application embodiment includes an inverter module 10 and a main control module 20 electrically connected to the inverter module 10. The inverter module 10 has a first connection terminal 11 and a second connection terminal 12. The first connection terminal 11 is used to connect to the on-board battery 201 of the target vehicle 200, and the second connection terminal 12 is used to connect to the target load 300. The inverter module 10 has at least a switchable first mode and a second mode. In the first mode, the inverter module 10 receives the power supply output from the on-board battery 201 through the first connection terminal 11, performs inverter conversion on the power supply to obtain the target power supply, and outputs the target power supply from the second connection terminal 12 to supply power to the target load 300. In the second mode, the inverter module 10 does not output the target power supply.

[0075] The main control module 20 is used to control the inverter module 10 to switch between the first mode and the second mode. As one embodiment, in the second mode, the inverter module 10 may either not perform inverter conversion on the power supply, or it may perform inverter conversion on the power supply to obtain the target power supply, but not output the target power supply from the second connection terminal 12.

[0076] As one embodiment, the main control module 20 may output a first control signal to the inverter module 10 to instruct the inverter module 10 to switch to a first mode, and / or output a second control signal to the inverter module 10 to instruct the inverter module 10 to switch to a second mode.

[0077] As one embodiment, the main control module 20 may control the inverter module 10 to switch to the first mode when the startup conditions are met. As an example and not a limitation, the startup conditions may be one or a combination of: receiving a startup command, triggering a preset startup button, and the power supply of the vehicle battery 201 being greater than a first threshold.

[0078] As one embodiment, the main control module 20 may control the inverter module 10 to switch to the second mode when a stop condition is met. As an example and not a limitation, the stop condition may be one or a combination of: receiving a stop command, triggering a preset stop button, and the power supply of the vehicle battery 201 being less than or equal to a second threshold.

[0079] It should be understood that, based on the above method, the main control module 20 can control the inverter module 10 to switch to the first mode or the second mode in order to realize the start and stop control of the inverter power supply to the target load 300.

[0080] like Figure 3 As shown, specifically, the main control module 20 is also used for:

[0081] Collect the status parameters of the target vehicle 200 to generate corresponding vehicle status information;

[0082] The vehicle status information is output to the target terminal 600.

[0083] As one embodiment, the main control module 20 forms a communication connection with the target vehicle 200. For example, the main control module 20 may form a wireless communication connection with the target vehicle 200 and collect the status parameters of the target vehicle 200 through wireless communication; or it may form a wired electrical connection with the target vehicle 200 through the electrical connection line 30 and collect the status parameters of the target vehicle 200 based on the electrical connection line 30.

[0084] For example, the status parameters of the target vehicle 200 include, but are not limited to, the tire pressure, coolant temperature, engine speed, headlight status, and air conditioning temperature of the target vehicle 200.

[0085] Specifically, the main control module 20 also establishes a communication connection with the target terminal 600, such as wireless communication, allowing the main control module 20 to transmit the collected vehicle status information to the target terminal 600. As one embodiment, the target terminal 600 is configured to display the received vehicle status information or transmit it to a user device, enabling the user to quickly and conveniently grasp the status of the target vehicle 200.

[0086] For example, the target terminal 600 can be at least one of an external cloud computing platform, an external server, or a local server. The target terminal 600 can also be an electronic device carried by the user, such as a smartphone, laptop, tablet or desktop computer, smart bracelet, smart ring, etc.

[0087] For example, the main control module 20 may include a programmable logic controller (PLC), a central processing unit (CPU), a microcontroller unit (MCU), other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The above are merely examples; any control module that can implement the functions of the main control module 20 falls within the protection scope of this application.

[0088] like Figure 3 As shown, in some embodiments, the main control module 20 can be communicatively connected to the target vehicle 200;

[0089] The main control module 20 collects the status parameters of the target vehicle 200 to generate corresponding vehicle status information, including:

[0090] Receive vehicle status data output by the target vehicle 200;

[0091] Based on a preset comparison relationship, target sub-state information corresponding to different types of state parameters is identified from vehicle state data.

[0092] Vehicle status information is generated based on the target sub-state information.

[0093] As one embodiment, the main control module 20 is connected to the bus 202 of the target vehicle 200 via an electrical connection cable 30. Specifically, the vehicle status data includes multiple sub-status data, and different sub-status data correspond to different types of status parameters. As in the previous example, the types of status parameters include, but are not limited to, the tire pressure, coolant temperature, engine speed, headlight status, air conditioning temperature, and other parameters of the target vehicle 200.

[0094] Furthermore, the main control module 20 can determine the target sub-state information corresponding to each state parameter from multiple sub-state data according to the comparison relationship. For example, the vehicle state data includes sub-state data N1 corresponding to tire pressure, sub-state data N2 corresponding to coolant temperature, and other sub-state data N3, N4, N5, etc. Different sub-state data are located in different positions in the vehicle state data. The main control module 20 can determine the sub-state data N1 corresponding to tire pressure and the sub-state data N2 corresponding to coolant temperature from multiple sub-state data according to the preset comparison relationship as target sub-state information, and then generate the vehicle state information by combining the above target sub-state information.

[0095] It should be noted that the correspondence relationship is specifically a one-to-one correspondence between sub-state data and state parameters. The following example illustrates the generation process of this correspondence relationship:

[0096] like Figure 3 , 4 As shown, in some embodiments, the process of generating the control relationship includes:

[0097] Parse the bus protocol of the target vehicle 200 to monitor the test data of the target vehicle 200;

[0098] Based on the currently operating functional modules in the target vehicle 200, identify the sub-test data corresponding to the functional modules from the test data;

[0099] A comparison relationship is generated based on the position of the subtest data in the test data.

[0100] Specifically, the bus 202 of the target vehicle 200 is a CAN bus. The higher-level protocols adopted by the CAN bus include J1939, ISO15765, and CANopen. As an example, and not a limitation, a CAN bus analyzer 400 can be used to parse the bus protocol of the target vehicle 200 to generate a comparison relationship. The following details the specific method for generating the above comparison relationship using a CAN bus analyzer 400:

[0101] A CAN bus analyzer 400 is used to access the OBD interface (CAN bus external interface) of the target vehicle 200. The CAN bus analyzer 400 parses the bus protocol of the target vehicle 200 to obtain the bus 202 data, i.e., the test data of the target vehicle 200. This test data includes multiple sub-test data (i.e., multiple CAN data lines). Then, the currently running functional modules in the target vehicle 200 are associated with the changed sub-test data. By sequentially determining the sub-test data corresponding to multiple functional modules in the above manner, the association between the status parameters of the functional modules and the sub-test data can be determined. Then, a correspondence between the status parameters and the sub-status data is generated based on the position of the sub-test data in the test data. It should be understood that the position of the sub-test data in the test data corresponds to the position of the sub-status data in the vehicle status data.

[0102] Furthermore, multiple sets of comparison relationships can be categorized to obtain a comparison relationship table corresponding to the target vehicle model 200. Similarly, various vehicle models equipped with OBD interfaces can be parsed step by step to form a database. Subsequently, the corresponding comparison relationship table can be directly retrieved from the database based on the model of the target vehicle 200.

[0103] As one example, testers can proactively trigger the operation of relevant functional modules and monitor the sub-test data that changes in the test data, thereby proactively determining the correspondence between the status parameters of the functional module and the sub-test data.

[0104] By embedding this part into the main control module 20 of the smart inverter 100, the main control module 20 can realize CAN mainline parsing and translation, and the smart inverter 100 can be seamlessly embedded into the control system of the target vehicle 200 in the future.

[0105] In some implementations, the status parameters include, but are not limited to, at least one of the following parameters: tire pressure, coolant temperature, engine speed, headlight status, and air conditioning temperature.

[0106] Specifically, the main control module 20 connects to the bus 202 of the target vehicle 200 and parses the bus protocol of the target vehicle 200 to monitor the test data of the target vehicle 200. For example, the vehicle status data includes multiple sub-state data, such as sub-state data N1 corresponding to tire pressure, sub-state data N2 corresponding to coolant temperature, and other sub-state data N3, N4, N5, etc. The different sub-state data are located in different positions in the vehicle status data. The main control module 20 can determine the sub-state data N1 corresponding to tire pressure and the sub-state data N2 corresponding to coolant temperature from the multiple sub-state data according to a preset reference relationship as target sub-state information. Then, it combines the above target sub-state information to generate vehicle status information. After transmitting the vehicle status information to the target terminal 600, the user can determine multiple status parameters such as tire pressure and coolant temperature based on the vehicle status information.

[0107] In some implementations, the status parameters also include the battery voltage of the on-board battery 201, and the main control module is further used for:

[0108] When the vehicle battery 201 is connected to the first interface terminal, the voltage of the first interface terminal of the inverter module 10 is sampled to obtain the voltage detection data of the vehicle battery 201.

[0109] Based on the voltage detection data, target sub-state information corresponding to the battery voltage is generated, and vehicle state information is generated based on the target sub-state information.

[0110] Specifically, the main control module 20 can directly collect voltage detection data from the first interface terminal, and then generate target sub-state information corresponding to the battery voltage based on the voltage detection data. After acquiring the target sub-state information corresponding to the battery voltage, the main control circuit can generate vehicle state information based on at least this target sub-state information, or it can generate vehicle state information by combining multiple target sub-state information (including the target sub-state information corresponding to the battery voltage) obtained from different state parameters. It should be understood that when the vehicle battery 201 is connected to the first interface terminal, the method of the main control circuit directly collecting voltage detection data from the first interface terminal is more accurate than the method of obtaining the battery voltage through communication transmission.

[0111] As one embodiment, the main control circuit can: when it detects that the vehicle battery 201 is connected to the first interface terminal, sample the voltage of the first interface terminal of the inverter module 10 to obtain voltage detection data of the vehicle battery 201, and generate target sub-state information corresponding to the battery voltage based on the voltage detection data; when it detects that the vehicle battery 201 is not connected to the first interface terminal, obtain the vehicle state data output by the target vehicle 200, and identify the target sub-state information corresponding to the battery voltage from the vehicle state data according to a preset comparison relationship. Based on the above embodiment, the main control circuit can flexibly select the more accurate battery voltage detection method according to the state of the vehicle battery 201 connected to the first interface terminal, improving the flexibility and accuracy of battery voltage detection.

[0112] As one embodiment, the main control circuit can detect whether the vehicle battery 201 is connected to the first interface terminal by: detecting the voltage value of the first interface terminal; when the voltage value of the first interface terminal is greater than a preset judgment threshold, it is determined that the vehicle battery 201 is connected to the first interface terminal; when the voltage value of the first interface terminal is less than or equal to the preset judgment threshold, it is determined that the vehicle battery 201 is not connected to the first interface terminal. For example, the above judgment threshold is 0V.

[0113] In one embodiment, the main control module 20 is connected to the first interface terminal for voltage acquisition. In another embodiment, the smart inverter 100 further includes a sampling circuit connected to the main control module 20 and the first interface terminal. The main control circuit acquires voltage data from the first interface terminal via the sampling circuit. When the vehicle battery 201 is connected to the first interface terminal, the main control circuit can obtain the voltage detection data of the vehicle battery 201 through the sampling circuit. In one embodiment, the sampling circuit includes, but is not limited to, one of an ADC sampling circuit, a voltage sampling conditioning circuit, and a sample-and-hold circuit.

[0114] In some implementations, the status parameters also include the positioning information of the target vehicle 200, wherein the positioning information includes the current positioning of the target vehicle 200 and / or the historical positioning of the target vehicle 200. It should be understood that the driving trajectory of the target vehicle 200 can also be obtained based on the historical positioning of the target vehicle 200 at multiple time points.

[0115] In some implementations, the main control module is also used for:

[0116] When the battery voltage is lower than a preset voltage threshold, a power supply reminder signal is output, and / or the inverter module 10 is controlled to switch to the second mode.

[0117] It should be noted that the power supply reminder signal is intended to alert the user that the on-board battery 201 of the target vehicle 200 has insufficient power and needs charging or is not suitable for continuing to output power. The power supply reminder signal is also used to remind the user to manually switch the inverter module 10 to the second mode. For example, some smart inverters 100 and / or the target vehicle 200 have a stop button, which the user can trigger to instruct the smart inverter 100 to switch the inverter module 10 to the second mode. In some embodiments, the inverter module 10 can also actively switch to the second mode when the battery voltage is lower than a preset voltage threshold. It should be understood that when the battery voltage is lower than the preset voltage threshold, if the smart inverter 100 actively or the user manually switches the inverter module 10 to the second mode, the inverter module 10 stops inverting and converting the power output from the on-board battery 201, preventing the on-board battery 201 from being depleted.

[0118] In some implementations, the main control module is also used to control the inverter module 10 to switch to a third mode when the charging operation is triggered. In the third mode, the inverter module 10 receives AC charging power through the second connection terminal 12, performs inverter conversion on the AC charging power to obtain DC charging power, and outputs the DC charging power from the first connection terminal 11 to charge the vehicle battery 201.

[0119] Specifically, in this embodiment, the inverter module 10 has a bidirectional inverter function, that is, it can invert DC power to AC power and AC power to DC power. As an example and not a limitation, the inverter module 10 is configured to invert AC power to DC power in the third mode. Specifically, when the charging operation is triggered, the inverter module 10 switches to the third mode. In the third mode, it receives AC charging power through the second connection terminal 12, inverts and converts the AC charging power to DC charging power, and outputs the DC charging power from the first connection terminal 11 to charge the vehicle battery 201.

[0120] As an example and not a limitation, the charging operation that triggers the main control module to switch to the third mode can be one or a combination of: receiving a charging command, triggering a preset charging button, or detecting that an AC charging power supply is connected to the second connection terminal 12 (e.g., the voltage of the second connection terminal 12 is greater than the third threshold).

[0121] Therefore, the intelligent inverter 100 in this embodiment has bidirectional inverter functionality. It can convert the DC power supply output from the vehicle battery 201 into an AC target power supply for external power supply, and it can also convert an externally connected AC charging power supply into a DC charging power supply to charge the vehicle battery 201. Moreover, the intelligent inverter 100 can intelligently switch between a first mode and a third mode based on startup conditions or charging operations, thereby flexibly adapting to various different application scenarios.

[0122] In some implementations, the main control module 20 is also used for:

[0123] The vehicle status information is encoded to obtain the corresponding status information code, and the status information code is output to the target terminal 600.

[0124] It should be understood that encoding vehicle status information and then transmitting the encoded status information can improve the security of information transmission, reduce the probability of information loss or mistransmission, and the encoded status information is more transmissible.

[0125] As one embodiment, the main control module 20 uses a transparent transmission protocol to encode the vehicle status information, resulting in an encoded status information.
