Description

Technical Field

[0001] This application relates to the field of charging and discharging technology, and in particular to a discharge control system and discharge device. Background Technology

[0002] In existing discharger systems, users select the corresponding single / dual discharge guns to insert into the battery gun socket discharge port, and then use the external touch screen located on the main cabinet to select the relevant operation interface to complete the start and stop operations, thereby realizing the battery discharge output.

[0003] Generally, a single-gun connection in a discharge system is sufficient for battery discharge. However, to achieve high current (e.g., 500A) output, simultaneous discharge from both guns is required. In practice, users may select the wrong guns and insert them before returning to the touchscreen to start the discharge process. In this case, there is no error message, and the simultaneous discharge function is not available. If the user discovers the wrong gun after discharge has started, they must stop the system on the touchscreen, return to the battery socket, re-insert and re-insert the discharge guns, and restart the discharge process. This cumbersome process significantly reduces user experience and discharge efficiency. If the user does not stop the system on the touchscreen before removing the wrong gun, arcing and gun burnout may occur due to the load output, potentially causing injury and greatly increasing safety risks. Even if the user selects the correct guns, they still need to insert them before returning to the main unit and clicking the touchscreen to complete the discharge process. Furthermore, the discharge gun cable can be 5-10 meters long, further compromising the user experience.

[0004] Therefore, it is necessary to provide a discharge control system and discharge device to solve the above-mentioned problems existing in the prior art. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this application is to provide a discharge control system and discharge device to solve the technical problem that the cumbersome operation process of using dual discharge guns in the prior art reduces the user experience.

[0006] To achieve the above and other related objectives, this application provides a discharge control system, comprising:

[0007] Multiple sets of discharge gun groups, each set of discharge gun groups includes two discharge guns for connection to the corresponding power battery;

[0008] A wireless control device is used to receive and determine the status information of the discharge gun. If the status information of the discharge gun indicates that the gun insertion is correct, it responds to the user's power-on operation information and transmits the power-on operation information. If the status information of the discharge gun indicates that the gun insertion is incorrect, it returns a gun insertion error message.

[0009] The control terminal includes a main control board, which is connected to the wireless control device and the discharge gun. The main control board is used to receive the start-up operation information transmitted by the wireless control device and send a start-up control command to the discharge gun according to the start-up operation information to control the power battery to start discharging.

[0010] Furthermore, the wireless control device includes a main wireless control device and a plurality of slave wireless control devices connected to the main wireless control device. Each slave wireless control device is connected to a corresponding discharge gun, and the main wireless control device is connected to the main control board.

[0011] Furthermore, the control terminal also includes a user interaction module, which is connected to the main control board and the main wireless control device. The user interaction module is used to display the status information of the discharge gun received by the main wireless control device from the wireless control device, and to transmit the start-up operation information received by the main wireless control device to the main control board.

[0012] Furthermore, both the master wireless control device and the slave wireless control device include a DIP switch, a wireless transceiver, a serial communication interface, and a controller, wherein the DIP switch, the wireless transceiver, and the serial communication interface are all connected to the controller.

[0013] Furthermore, both the main wireless control device and the slave wireless control device also include a gun insertion indicator light, a start button, a stop button, and a start / stop status indicator light, all of which are connected to the controller.

[0014] Furthermore, both the master wireless control device and the slave wireless control device also include a power module, a power indicator light, a power charging port, a charging indicator light, and a switch. The power module, the power indicator light, and the charging indicator light are all connected to the controller. The power charging port is connected to the power module. The switch is used to turn the master wireless control device and the slave wireless control device on and off.

[0015] Furthermore, the wireless transceiver is an RF433M.

[0016] Furthermore, the control terminal also includes a switch and multiple battery management system control boards. One port of the switch is connected to the main control board, and the other multiple ports of the switch are connected to the battery management system control boards one by one.

[0017] Furthermore, the control terminal also includes multiple DC / DC modules, which are connected to the battery management system control board one by one.

[0018] To achieve the above and other related objectives, this application also provides a discharge device, comprising:

[0019] As described above, the discharge control system and discharge device of this application have the following beneficial effects:

[0020] By connecting two discharge guns to one power battery, the wireless control device first receives and judges the status information of the discharge guns. If the status information indicates that the guns are correctly inserted, the wireless control device responds to the user's start-up operation information and transmits the start-up operation information to the main control board of the control terminal. The main control board receives and processes the start-up operation information to generate a start-up control command, which is transmitted to the power battery through the discharge guns to control the start-up discharge of the power battery. If the status information indicates that the guns are incorrectly inserted, an error message is returned. The user then re-inserts the guns according to the message to ensure correct insertion before starting the power battery. This application, while achieving high-power output from the power battery, can identify the current insertion status of the discharge guns in real time. When the insertion is correct, it supports remote start-up operation; when the insertion is incorrect, it supports an error message function, thereby simplifying the discharge operation process, improving the user experience, and increasing discharge efficiency.

[0034] <5> Battery Management System (BMS): A battery management system is an electronic system specifically designed to monitor and manage battery energy storage units. It is mainly used in electric vehicles, energy storage systems, drones, portable electronic devices, and other applications. The main purpose of BMS is to ensure the safe, efficient, and balanced operation of the battery pack, extend battery life, and provide accurate battery status information.

[0035] To facilitate understanding of the embodiments of this application, firstly, in conjunction with Figure 1 and Figure 2 Detailed explanation. For example... Figure 1 and Figure 2 As shown, a discharge control system 100 in an embodiment of the present invention includes:

[0036] Multiple sets of discharge gun groups 10, each set of discharge gun groups 10 includes two discharge guns 11 for connecting to the corresponding power battery;

[0037] The wireless control device 20 is used to receive and determine the status information of the discharge gun 11. If the status information of the discharge gun 11 indicates that the gun insertion is correct, it responds to the user's power-on operation information and transmits the power-on operation information. If the status information of the discharge gun indicates that the gun insertion is incorrect, it returns a gun insertion error message.

[0038] The control terminal 30 includes a main control board 31, which is connected to the wireless control device 20 and the discharge gun 11. The main control board 31 is used to receive the start-up operation information transmitted by the wireless control device 20 and send a start-up control command to the discharge gun 11 according to the start-up operation information to control the power battery to start discharging.

[0039] The system connects two discharge guns 11 to one power battery. The wireless control device 20 first receives and judges the status information of the discharge guns 11. If the status information of the discharge guns 11 indicates that the insertion is correct, the wireless control device 20 responds to the user's start-up operation information and transmits the start-up operation information to the main control board 31 of the control terminal 30. The main control board 31 receives and processes the start-up operation information to generate a start-up control command, which is transmitted to the power battery through the discharge guns 11 to control the start-up discharge of the power battery. If the status information of the discharge guns 11 indicates that the insertion is incorrect, an insertion error message is returned. The user re-inserts the guns according to the message to ensure that the insertion is correct before starting the power battery. This application, while achieving high-power output of the power battery, identifies the current insertion status of the discharge guns in real time. When the insertion is correct, it supports remote start-up operation; when the insertion is incorrect, it supports an insertion error message function, simplifying the discharge operation process, improving the user experience, and increasing discharge efficiency.

[0040] Specifically, each discharge gun group 10 is connected to one power battery, meaning the number of discharge gun groups 10 is the same as the number of power batteries. The main control board 31 can simultaneously control the discharge process of multiple power batteries.

[0041] In some embodiments of this application, such as Figure 2 As shown, the wireless control device 20 includes a main wireless control device 21 and multiple slave wireless control devices 22 connected to the main wireless control device 21. Each slave wireless control device 22 is connected to a discharge gun 11 in a one-to-one correspondence. That is, the number of slave wireless control devices 22 is the same as the number of discharge guns 11. For example, each slave wireless control device 22 is embedded in a corresponding discharge gun 11, thereby receiving information parameters such as the insertion status, discharge status, and fault status of the discharge gun 11. Based on the insertion status information, it determines whether the discharge gun 11 is inserted correctly. If the insertion is correct, the user performs a power-on operation; if the insertion is incorrect, the user removes the incorrect discharge gun 11, re-inserts the correct discharge gun 11, and then performs a power-on operation. By providing information prompts from the slave wireless control devices 22 indicating whether the insertion is correct, the user can promptly know whether the insertion is correct. Compared to existing technologies, this simplifies the operation process and improves the user experience.

[0042] The main wireless control device 21 is connected to the main control board 31. In this embodiment, one main wireless control device 21 interacts with multiple slave wireless control devices 22. Specifically, the slave wireless control devices 22, which are mounted on the discharge gun 11, transmit information parameters such as the insertion status, discharge status, and fault status of the discharge gun 11, as well as user-initiated start-up operation information, to the main wireless control device 21. The main wireless control device 21 transmits the received start-up operation information to the main control board 31, which then generates a start-up control command based on the start-up operation information to control the start-up discharge of the power battery. Simultaneously, the main wireless control device 21 also transmits the received data information to each slave wireless control device 22, which in turn transmits it to each discharge gun 11, thus completing the communication interaction process.

[0043] In some embodiments of this application, such as Figure 1 As shown, the control terminal 30 also includes a user interaction module 32. The user interaction module 32 is connected to the main control board 31 and the main wireless control device 21, and is used to display the status information of the discharge gun 11 received by the main wireless control device 21 from the slave wireless control device 22, and to transmit the start-up operation information received by the main wireless control device 21 to the main control board 31. For example, the main wireless control device 21 is embedded in the user interaction module 32. The user interaction module 32 wirelessly transmits the data information input by the user through the operation interface to the slave wireless control device 22, and then the slave wireless control device 22 transmits it to each discharge gun 11, thereby adjusting the discharge parameters of the corresponding discharge gun 11. Meanwhile, the main wireless control device 21 inputs the information parameters received from the wireless control device 22, such as the insertion status information, discharge status information, and fault status information of the discharge gun 11, into the user interaction module 32 for display. The user interaction module 32 also transmits the start-up operation information received by the main wireless control device to the main control board 31 to start the discharge of the power battery.

[0044] In some embodiments of this application, such as Figure 3 As shown, both the master wireless control device 21 and the slave wireless control device 22 include a DIP switch 211, a wireless transceiver 212, a serial communication interface 213, and a controller 214. The DIP switch 211, the wireless transceiver 212, and the serial communication interface 213 are all connected to the controller 214.

[0045] In this embodiment, the DIP switch 211 is used to set the addresses of the master wireless control device 21 and the slave wireless control device 22, thereby determining the binding relationship between the master wireless control device 21 and the user interaction module 32, and the binding relationship between the slave wireless control device 22 and the corresponding discharge gun 11. Specifically, the DIP switch 211 is connected to the controller 214 through a GPIO interface to achieve fast signal transmission and response. For example, the DIP switch 211 has 4 bits (from left to right, bits 1 to 4). The 4-bit DIP switch 211 has 16 states (from 0000 to 1111), which can represent numbers from 0 to 15. Each DIP switch has two states, 0 and 1, which are set by toggling the switch.

[0046] The following description uses three groups of discharge guns 10 corresponding to six discharge guns 11 as an example. Address settings are completed according to the discharge gun numbers (first discharge gun, second discharge gun, third discharge gun, fourth discharge gun, fifth discharge gun, and sixth discharge gun) and via DIP switch 211. The preset address setting rules are: default 0 is the primary address, bound to the user interaction module 32, and the DIP switch is set to 0000; non-zero addresses are slave addresses, bound to the discharge guns 11. For the six discharge guns 11, the address range is 1 to 6. The address of the primary wireless control device 21 (user interaction module 32) is 0, represented in binary as 0000, and all switches of DIP switch 211 are in the "OFF" state. The address of the first slave wireless control device (first discharge gun) is 1, represented in binary as 0001, with the 4th bit of DIP switch 211 "ON" and the other bits "OFF". The address of the second slave wireless control device (second discharge gun) is 2, represented as 0010 in binary. Bit 3 of DIP switch 211 is "ON," and the other bits are "OFF." The address of the third slave wireless control device (third discharge gun) is 3, represented as 0011 in binary. Bits 3 and 4 of DIP switch 211 are "ON," and the other bits are "OFF." The address of the fourth slave wireless control device (fourth discharge gun) is 4, represented as 0100 in binary. Bit 2 of DIP switch 211 is "ON," and the other bits are "OFF." The address of the fifth slave wireless control device (fifth discharge gun) is 5, represented as 0101 in binary. Bits 2 and 4 of DIP switch 211 are "ON," and the other bits are "OFF." The address of the sixth slave wireless control device (sixth discharge gun) is 6, represented as 0110 in binary. Bits 2 and 3 of DIP switch 211 are "ON," and the other bits are "OFF." After the user interaction module 32 (master device) is started, it scans the address range to find the discharge gun 11 (slave device). Each discharge gun 11 responds to the scanning request of the user interaction module 32 according to the address of the DIP switch, and establishes a communication connection between the user interaction module 32 and each discharge gun 11 through wireless signal, so as to realize effective communication and control between the user interaction module 32 and each discharge gun 11.

[0047] In this embodiment, the wireless transceiver 212 of the main wireless control device 21 receives the start-up operation information sent by the wireless transceiver 212 of the wireless control device 22, and transmits the start-up operation information to the controller 214 of the main wireless control device 21. After processing by the controller 214, the information is sent to the user interaction module 32 through the serial communication interface 213 of the main wireless control device 21. The user interaction module 32 then inputs the information to the main control board 31 to control the start-up of the discharge device. Simultaneously, the main wireless control device 21 sends user interaction information to the slave wireless control device 22 through its wireless transceiver 212. The slave wireless control device 22 receives the user interaction information and sends it to the controller 214 of the slave wireless control device 22. After processing by the controller 214, the information is sent to the corresponding discharge gun 11 through the serial communication interface 213 of the slave wireless control device 22, thereby controlling the discharge parameters and other information of the discharge gun 11.

[0048] Specifically, both the wireless transceiver 212 and the serial communication interface 213 communicate bidirectionally with the controller 214 via the serial port, which is simple to use and has a low cost.

[0049] In some embodiments of this application, such as Figure 3 As shown, both the main wireless control device 21 and the slave wireless control device 22 further include a gun insertion indicator 215, a power-on button 216, a power-off button 217, and a power-on / power-off status indicator 218. The gun insertion indicator 215, the power-on button 216, the power-off button 217, and the power-on / power-off status indicator 218 are all connected to the controller 214. For example, the gun insertion indicator 215, the power-on button 216, the power-off button 217, and the power-on / power-off status indicator 218 are all connected to the controller 214 via a GPIO interface.

[0050] Specifically, after the user inserts the discharge gun 11, the discharge gun 11 transmits its insertion status information to the controller 214 via the serial communication interface 213 of the wireless control device 21. The controller 214 determines whether the insertion is correct based on the insertion status information and controls the insertion indicator light 215 accordingly. For example, if only one gun is inserted, the insertion indicator light 215 is solid white; if both guns are inserted correctly, the insertion indicator light 215 is solid green; if both guns are inserted incorrectly, the insertion indicator light 215 flashes red. By setting the insertion indicator light 215, the user can view the insertion status in real time. If an insertion error occurs, it can be corrected before startup, simplifying the operation process and improving discharge efficiency. Simultaneously, the wireless control device 22 also sends the insertion status information to the user interaction module 32 via the main wireless control device 21 for display, allowing the user to easily view the information.

[0051] Specifically, if both guns are inserted correctly, pressing the start button 216 on the slave wireless control device 22 triggers the start button 216. The controller 214 of the slave wireless control device 22 responds to the user's start operation, generating start operation information. This information is transmitted from the slave wireless control device 22's wireless transceiver 212 to the main wireless control device 21's wireless transceiver 212. The main wireless control device 21's wireless transceiver 212 then transmits the received start operation information to its controller 214. After processing by the controller 214, the information is sent to the user interaction module 32 via the serial communication interface 213. The user interaction module 32 then inputs this information to the main control board 31 to control the start of the discharge equipment. This embodiment, by designing a start button 216 on the slave wireless control device 22, allows the user to start the discharge equipment directly without returning to the touchscreen after correct gun insertion, significantly saving operation time and improving discharge efficiency. Of course, users can also choose to trigger the power-on button 216 of the main wireless control device 21.

[0052] Specifically, by designing a stop button 217 on both the main wireless control device 21 and the slave wireless control device 22, the user can choose to trigger the stop button 217 at the location where the discharge gun 11 is placed or at the location of the user interaction module 32, thereby stopping the discharge process of the discharge device. By designing a start button 216 and a stop button 217, the user can remotely control the start and stop of the discharge device, saving the user's operation time for discharge.

[0053] Specifically, start / stop status indicator lights 218 are designed on the main wireless control device 21 and the slave wireless control device 22. After the start button 216 and the stop button 217 are triggered, the start / stop status indicator lights 218 can be viewed in real time, allowing users to check whether the device has started or stopped. For example, after the start button 216 is triggered, if the start command is successful, the start / stop status indicator light 218 will be solid green; if the start command fails, the start / stop status indicator light 218 will be solid yellow and turn off after 3 seconds. After the stop button 217 is triggered, if the stop command is successful and the stop is in progress, the start / stop status indicator light 218 will flash green; if the stop is successful, the start / stop status indicator light 218 will be off; if the stop command fails, the start / stop status indicator light 218 will remain unchanged. Simultaneously, when the entire discharge equipment malfunctions, the start / stop status indicator light 218 will be solid yellow, serving as a synchronous fault indication.

[0054] In some embodiments of this application, such as Figure 3 As shown, both the master wireless control device 21 and the slave wireless control device 22 further include a power module 219, a power indicator light 220, a power charging port 221, a charging indicator light 222, and a switch 223. The power module 219, the power indicator light 220, and the charging indicator light 222 are all connected to the controller 214; the power charging port 221 is connected to the power module 219; and the switch 223 is used to turn the master wireless control device 21 or the slave wireless control device 22 on and off. For example, the power module 219, the power indicator light 220, and the charging indicator light 222 are all connected to the controller 214 via a GPIO interface.

[0055] Specifically, the power module 219 of the main wireless control device 21 supplies power to the main wireless control device 21, and the power module 219 of the slave wireless control device 22 supplies power to the slave wireless control device 22. The charging port 221 is connected to the power module 219 and provides a charging interface when the power module 219 has insufficient power.

[0056] Specifically, the user turns on the main wireless control device 21 by activating switch 223, and turns on the secondary wireless control device 22 by activating switch 223. The user can then check the status of the power indicator light 220 to promptly determine if the power module 219 has sufficient power. For example, if the power indicator light 220 is constantly on, it indicates sufficient power; if the power indicator light 220 is flashing, it indicates insufficient power and requires charging. During the charging process of the power module 219, the charging indicator light 222 remains on and turns off when fully charged.

[0057] In some embodiments of this application, the wireless transceiver 212 is an RF433M. The RF433M is selected for the wireless transceiver 212 because of its long-distance transmission capability, strong penetration, resistance to environmental interference, industrial-grade stability, low power consumption, and low cost, which can meet the wireless communication transmission requirements between the wireless control device 22 and the main wireless control device 21.

[0058] In some embodiments of this application, such as Figure 1 As shown, the control terminal 30 also includes a switch 33 and multiple battery management system control boards 34. One port of the switch 33 is connected to the main control board 31, and the other ports of the switch 33 are connected one-to-one with the battery management system control boards 34. The battery management system control board 34 will be referred to as the BMS control board 34 below. In this embodiment, the switch 33 enables data transmission between the main control board 31 and the BMS control board 34, providing a high-speed and stable communication channel. This allows the main control board 31 to send control commands to the BMS control board 34, while the BMS control board 34 can also feed back battery status information to the main control board 31.

[0059] It should be noted that the control terminal 30 includes N BMS control boards 34, where N is a positive integer and N≥1. Furthermore, the number of BMS control boards 34 is the same as the number of discharge gun groups 10 and the number of power batteries.

[0060] In some embodiments of this application, such as Figure 1 As shown, the control terminal 31 also includes multiple DC / DC modules 35, each connected to the battery management system control board 34. In this embodiment, the DC / DC module 35 is a power conversion module used to convert one DC voltage (DC, Direct Current) to another, thereby realizing the conversion between different voltage levels. This ensures that the output voltage of power batteries with different voltages can be stably maintained within a certain voltage range, meeting the power supply requirements for external devices.

[0061] Specifically, the number of DC / DC modules 35 is the same as the number of BMS control boards 34, and the DC / DC modules 35 and BMS control boards 34 achieve bidirectional communication for data exchange. That is, during discharge, the BMS control board 34 sends control commands to the DC / DC modules 35 based on the monitored state information of the power battery. The DC / DC modules 35 then convert the voltage of the power battery to a voltage suitable for the load based on the received control commands. Simultaneously, the DC / DC modules 35 transmit feedback information to the BMS control board 34, which then evaluates parameters such as voltage, current, and temperature of the power battery based on the feedback information. Through the coordinated work of the DC / DC modules 35 and the BMS control board 34, the discharge efficiency of the power battery is optimized, and the service life of the power battery is extended.

[0062] It should be noted that there are many types of data information transmitted between the various components in the discharge control system 100 of this invention. This article mainly describes the start-up operation information and the status information of the discharge gun. The transmission process of other types of data will not be described in detail here.

[0063] Figure 4 A schematic diagram of a discharge device according to an embodiment of the present invention is shown. Figure 3 As shown, the discharge device 1000 includes: the aforementioned discharge control system 100 and multiple power batteries 200. The discharge control system 100 is connected to the multiple power batteries 200 and is used to control the discharge of the multiple power batteries. In addition, the discharge device 1000 also includes multiple PCS modules 300, each PCS module 300 being connected to a corresponding DC / DC module 35 in the discharge control system 100. It should be understood that the PCS module is a power conversion system, capable of converting the DC power output from the battery into AC power for use by the power grid or load; simultaneously, it can also rectify the AC power from the power grid into DC power to charge the battery. Through the connection of the PCS module 300 to the DC / DC module 35, the stable DC power from the DC / DC module 35 is converted into AC power for use by the load.

[0064] It should be noted that the number of BMS control board 34, DC / DC module 35, PCS module 300, and discharge gun group 10 are all the same, and there are N of each, where N is a positive integer and N≥1. The discharge guns 11 of the Nth discharge gun group 10 are the 2*N-1th discharge gun and the 2*Nth discharge gun, respectively. The number of wireless control devices 22 corresponds to the number of discharge guns 11.

[0065] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.

[0066] In summary, to address the technical problem of cumbersome operation procedures that reduce user experience when using dual discharge guns in existing technologies, this invention provides a discharge control system and discharge device. Each pair of discharge guns is connected to a power battery. A wireless control device first receives and judges the status information of the discharge guns. If the status information indicates correct insertion, the wireless control device responds to the user's start-up operation and transmits the start-up operation information to the main control board of the control terminal. The main control board receives and processes the start-up operation information, generates a start-up control command, and transmits the start-up control command to the power battery through the discharge guns to control the power battery. The system initiates the discharge of the battery. If the discharge gun's status information indicates an incorrect insertion, an error message is returned, allowing the user to re-insert the gun and ensure correct insertion before restarting. This application, while achieving high-power output from the battery, can identify the current discharge gun's insertion status in real time. When the insertion is correct, it supports remote start-up; when the insertion is incorrect, it provides an error message, improving error correction capabilities. Simultaneously, this application enables remote shutdown, real-time monitoring of start / stop and fault status, simplifying the discharge process, improving user experience, and increasing discharge efficiency. Therefore, this application effectively overcomes the shortcomings of existing technologies and possesses high industrial applicability.

[0067] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
