[0033] In the field of energy management, current multi-battery management system container management solutions mainly involve each battery management system container managing its own container through its own energy management system. In other words, with several battery management system containers, management and control require sequential and repetitive operation of several energy management systems. It is evident that current multi-battery management system container management solutions involve a lot of repetitive work and have low management efficiency.

[0034] To address the aforementioned issues, this application proposes a master-slave battery management system, which aims to enable the management of multiple battery management system containers through a single energy management system, thereby reducing the workload when managing multiple battery management system containers simultaneously and improving management efficiency.

[0035] Figure 1 This is a schematic diagram of a master-slave battery management system structure provided in an embodiment of this application, as shown below. Figure 1 As shown, the master-slave battery management system may include: an energy management system master 11, at least one energy management system slave 13, a master container controller 12 corresponding to the energy management system master 11, at least one slave container controller 14 corresponding to the energy management system slave 13, and an energy storage converter 15.

[0036] The energy management system host 11 is communicatively connected to the energy storage converter 15, the host container controller 12, and the energy management system slave 13; the energy management system slave 13 is also communicatively connected to the corresponding slave container controller 14; the energy storage converter 15 is also connected to the host container controller 12 and at least one slave container controller 14.

[0037] For example, the energy management system host 11 and energy management system slave 13 may be devices such as computers with data processing and communication functions, which are communicatively connected to the host container controller 12 or the slave container controller 14.

[0038] The energy management system host 11 can generate and send corresponding control commands to the host container controller 12, slave container controller 14, or energy storage converter 15 based on the operations of the management personnel, so as to control the equipment in the host container or slave container, or control the electrical connection status between the energy storage converter 15 and the battery pack in the host container or slave container. The energy management system host 11 or the energy management system slave 13 can also receive sampling and detection data from, for example, the host container controller 12 and the slave container controller 14, and display it to the management personnel through, for example, the display screen of the energy management system host 11.

[0039] If the energy management system slave 13 receives sampling and detection data from the slave container controller 14, etc., the energy management system slave 13 can forward the sampling and detection data received from the slave container controller 14, etc. to the energy management system master 11 through the communication connection, and display the data on the display screen of the energy management system master 11, etc. for the manager, etc. Of course, the above is only an example, and the energy management system master 11 and the energy management system slave 13 can be any device and have any function according to the actual situation, which is not limited herein.

[0040] The master container controller 12 and the slave container controller 14 can be devices having data processing and communication functions, such as MCU (Microcontroller Unit), VCU (Vehicle Control Unit), ECU (Electronic Control Unit), etc., and can control the opening and closing of devices in the master container or the slave container, such as air conditioners, etc., according to the control instructions from the energy management system master 11 and the energy management system slave 13, etc. The master container controller 12 and the slave container controller 14 can also control the electrical connection state of the energy storage converter 15 and the battery pack in the master container or the slave container, such as AC charging or DC discharging, etc. The master container controller 12 and the slave container controller 14 can also collect the running state information of the air conditioners, the battery pack, etc. and send the information to the energy management system master 11 and the energy management system slave 13, etc. Of course, the above is only an example, and the master container controller 12 and the slave container controller 14 can be any device and have any function according to the actual situation, which is not limited herein.

[0041] The above-mentioned energy storage converter 15 can also be referred to as a PCS (Power Conversion System) in the related art, which is connected with the above-mentioned master container controller 12 and at least one of the above-mentioned slave container controller 14, for example, can refer to the energy storage converter 15 which is controlled to realize the electrical connection between the energy storage converter 15 and the battery pack in the master container or slave container according to the control instruction from the above-mentioned energy management system master 11, etc., through the above-mentioned master container controller 12 or slave container controller 14, and then controls the charging and discharging process of the battery pack in the master container or slave container, for example, performs AC-DC conversion, to realize, for example, the above-mentioned AC charging or DC discharging, etc. Of course, the above-mentioned content is all possible examples, and the specific model, parameter and specific function of the above-mentioned energy storage converter 15 can be selected and determined according to the actual situation, which is not limited here.

[0042] The communication connection between the above-mentioned devices can be, for example, a communication connection mode including but not limited to CAN (Controller Area Network, Controller Area Network) communication connection, Modbus TCP (Modbus Transmission Control Protocol, Modbus Transmission Control Protocol) communication connection, and COM (Cluster Communication Port, Serial Communication Interface) communication connection, etc. The specific communication connection mode can be selected and determined according to the actual situation.

[0043] The master-slave battery management system provided by the embodiment of the application comprises an energy management system master 11, at least one energy management system slave 13, a master container controller 12 corresponding to the energy management system master 11, at least one slave container controller 14 corresponding to the energy management system slave 13, and an energy storage converter 15. The energy management system master 11 is in communication connection with the energy storage converter 15, the master container controller 12 and the energy management system slave 13. The energy management system slave 13 is also in communication connection with the corresponding slave container controller 14. The energy storage converter 15 is also connected with the master container controller 12 and at least one slave container controller 14. By dividing a plurality of energy management systems into a master and at least one slave, the energy management system master 11 can be used to control or monitor the energy management system master 11 and each energy management system slave 13 at the same time, and it is not necessary to manage each battery management system container through the energy management system in the battery management system container one by one. Therefore, one energy management system can be used to manage a plurality of battery management system containers, which reduces the workload when a plurality of battery management system containers need to be managed at the same time and improves the management efficiency.

[0044] Figure 2 The structure schematic diagram of master-slave battery management system provided for another embodiment of the present application is shown in Figure 2 Figure 1 On the basis of the embodiment, the master-slave battery management system can further include: a communication manager host 21 corresponding to the energy management system host 11, and a communication manager slave 22 corresponding to each energy management system slave 13.

[0045] The energy management system host 11 is in communication connection with the host container controller 12 through the communication manager host 21, and the energy management system host 11 is in communication connection with the energy management system slave 13 through the communication manager host 21 and the communication manager slave 22.

[0046] The energy management system slave 13 is in communication connection with the corresponding slave container controller 14 through the corresponding communication manager slave 22.

[0047] For example, the communication manager host 21 and the communication manager slave 22 can also be called DPU (Data Processing Unit) in the related field. The communication manager host 21 and the communication manager slave 22 can have multiple downlink communication interfaces and one or more uplink network interfaces, so as to send the running state information of the air conditioner, the battery pack and other devices collected and obtained by the host container controller 12 and the slave container controller 14 to the corresponding energy management system host 11 or energy management system slave 13 after sorting and summarizing, and to forward the control instructions of the energy management system host 11 or the energy management system slave 13 to the host container controller 12, the slave container controller 14 or the energy storage converter 15.

[0048] Of course, the specific type, model, parameter, function and the like of the communication manager host 21 and the communication manager slave 22 can be selected and adjusted according to the actual situation, and are not limited to the above.

[0049] ​The brake system provided by the embodiment further comprises a communication manager master 21 corresponding to the energy management system master 11, and a communication manager slave 22 corresponding to each energy management system slave 13. The energy management system master 11 is in communication connection with the master container controller 12 through the communication manager master 21. The energy management system master 11 is in communication connection with the energy management system slave 13 through the communication manager master 21 and the communication manager slave 22. The energy management system slave 13 is in communication connection with the slave container controller 14 through the corresponding communication manager slave 22. The energy management system master 11 and the energy management system slave 13 are in communication connection with other devices through the corresponding communication manager master 21 or communication manager slave 22, which reduces the direct processing of data and information by the energy management system master 11 and the energy management system slave 13, thereby reducing the data processing pressure of the energy management system master 11 and the energy management system slave 13, and enhancing the data transmission efficiency and stability.

[0050] Figure 3 The master-slave battery management system structure schematic diagram provided by another embodiment of the application is shown in FIG. 4. Figure 3 In the above Figure 2 On the basis of the above embodiment, the energy management system master 11 can be integrated in the corresponding communication manager master 21. The communication manager master 21 comprises an internal communication interface and an external communication interface. The energy management system master 11 is in communication connection with the corresponding energy management system master 11 through the internal communication interface, and in communication connection with the master container controller 12 and each communication manager slave 22 through the external communication interface.

[0051] The energy management system slave 13 is integrated in the corresponding communication manager slave 22. The communication manager slave 22 comprises the internal communication interface and the external communication interface. The energy management system slave 13 is in communication connection with the corresponding energy management system slave 13 through the internal communication interface, and in communication connection with the corresponding slave container controller 14 and the communication manager master 21 through the external communication interface.

[0052] For example, the energy management system host 11 can be integrated into the corresponding communication manager host 21, and the energy management system slave 13 can be integrated into the corresponding communication manager slave 22. For example, it can be referred to that the communication manager host 21 includes an energy management system host 11, and the communication manager slave 22 includes an energy management system host 11 slave. The energy management system host 11 is connected to the communication manager host 21 through the internal interface of the communication manager host 21, and the energy management system slave 13 is connected to the communication manager slave 22 through the internal interface of the communication manager host 21. The internal communication interface and the external communication interface can be, for example, a communication interface corresponding to the communication connection mode of the CAN communication connection, the Modbus TCP communication connection, and the COM communication connection, but are not limited thereto.

[0053] The energy management system host 11 can be integrated into the corresponding communication manager host 21, and the energy management system slave 13 can be integrated into the corresponding communication manager slave 22. The communication manager host 21 and the communication manager slave 22 can also have the functions of the energy management system host 11 or the energy management system slave 13, so as to replace the energy management system host 11 or the energy management system slave 13 to realize the related functions. It can be understood that in this case, the energy management system host 11 or the energy management system slave 13 can not exist in the communication manager host 21 and the communication manager slave 22, and correspondingly, the internal communication interface can not exist. Of course, the above content is only an example, and the integration of the energy management system host 11 into the corresponding communication manager host 21 and the integration of the energy management system slave 13 into the corresponding communication manager slave 22 can be in any form, which can be selected and determined according to the actual situation, and is not limited to the above content.

[0054] The communication manager host 21 can be installed with a preset control program, when the preset control program runs, the communication manager host 21 can configure threads for the device objects that need to receive or send information according to a preset configuration file (for example, a thread can be configured for each communication manager slave 22, energy storage converter 15, host container controller 12 and slave container controller 14), each thread can receive or send information according to the preset rules in the preset configuration file, and after receiving the information, the communication manager host 21 can process and integrate the information according to the preset rules in the preset configuration file, and store the information before and after the processing and integration, so that the relevant staff can locate and troubleshoot the possible information transmission problems. It can be understood that the specific content of the configuration file and the preset rules can be determined according to the actual information type, information format, etc., and is not limited here.

[0055] Optionally, please continue to refer to Figure 3 On the basis of the above embodiment, the master-slave battery management system can further include at least two container bodies 31.

[0056] The communication manager host 21 and the host container controller 12 are placed in a corresponding container body 31.

[0057] The communication manager slave 22 and the corresponding slave container controller 14 are placed in a corresponding container body 31 as a group of devices.

[0058] For example, the material of the container body 31 can be metal or other composite material, and the container body 31 can be provided with holes for passing through wires, cables or communication harnesses, etc. In addition to the communication manager host 21 and the host container controller 12, the communication manager slave 22 and the corresponding slave container controller 14, the container body 31 can also include devices such as the battery pack and the air conditioner. The battery pack can be electrically connected to the external power grid through the energy storage converter 15 and the like, and when the external power grid has sufficient power, it can receive the charging of the battery pack by the external power grid through the energy storage converter 15 and the like, and when the external power grid has insufficient power, it can discharge the external power grid through the energy storage converter 15. The air conditioner can be used for cooling or heat preservation of the battery pack. Of course, the above content is only an example, and the material, shape, size of the container body 31, and the specific type, number and model of the devices inside the container body 31 can be selected and adjusted according to the actual situation, and are not limited to the above content.

[0059] Further, as Figure 3As shown, the master-slave battery management system can further include at least two uninterruptible power supplies 41. Each of the at least two uninterruptible power supplies 41 is arranged in a container 31. The uninterruptible power supply 41 is electrically connected to the communication manager master 21 or the communication manager slave 22 in the container 31.

[0060] For example, the number of the uninterruptible power supplies 41 can be equal to the number of the containers 31. The uninterruptible power supply 41 can be used to supply power to the communication manager master 21 and the communication manager slave 22 to ensure that the communication manager master 21 or the communication manager slave 22 can keep running to manage and detect the devices in the container 31 uninterruptedly.

[0061] It can be understood that when the container 31 is provided with devices or equipment for detecting the environment in the container 31 and ensuring the safe operation of the devices in the container 31, such as a gas detection device and a temperature detection device, the uninterruptible power supply 41 can also supply power to the devices or equipment for detecting the environment in the container 31 and ensuring the safe operation of the devices in the container 31, such as the gas detection device and the temperature detection device. Of course, the above is only an example, and the specific type, model, and purpose of the uninterruptible power supply 41 can be selected and determined according to actual needs, and are not limited to the above.

[0062] In addition, please continue to refer to Figure 3 The master-slave battery management system can further include at least two current sensors 42. Each of the at least two current sensors 42 is arranged in a container 31. The current sensor 42 is communicatively connected to the communication manager master 21 or the communication manager slave 22 in the container 31.

[0063] For example, the number of the current sensors 42 can be equal to the number of the containers 31. The current sensor 42 can be connected to the circuit in which the battery pack is arranged and used to detect the current value in the circuit. The detection can be real-time or periodic, for example, detection every 10 seconds or every 1 minute, which is not limited herein. After detecting the current value in the circuit in which the battery pack is arranged, the current sensor 42 can send the current value to the communication manager master 21 or the communication manager slave 22 through the communication connection. If the current value is sent to the communication manager slave 22, the communication manager slave 22 can further forward the current value to the communication manager master 21 through the communication connection.

[0064] In a possible scenario, the current sensor 42 can also be in communication connection with the master container controller 12 or the slave container controller 14, and send the detected current value to the communication manager master 21 or the communication manager slave 22 through the master container controller 12 or the slave container controller 14.

[0065] Of course, the above is only a possible example, and the specific type, model, function, communication connection object, etc. of the current sensor 42 can be selected and determined according to the actual situation, and is not limited to the above.

[0066] Further, please continue to refer to Figure 3 The master-slave battery management system can also include at least two gas detection devices 43, each of the at least two gas detection devices 43 is placed in a container body 31, and the gas detection device 43 is in communication connection with the communication manager master 21 or the communication manager slave 22 in the container body 31.

[0067] For example, the number of gas detection devices 43 can be equal to the number of container bodies 31, and the gas detection device 43 can be used for air composition detection in the container body 31, which can be real-time or periodic, such as detection every 10 seconds or every 1 minute, etc. without limitation. After detecting the air composition in the container body 31, the gas detection device 43 can send the air composition to the communication manager master 21 or the communication manager slave 22 through the communication connection, and if it is sent to the communication manager slave 22, the communication manager slave 22 can also forward the air composition to the communication manager master 21 through the communication connection.

[0068] In a possible scenario, the gas detection device 43 can also be in communication connection with the master container controller 12 or the slave container controller 14, and send the detected air composition to the communication manager master 21 or the communication manager slave 22 through the master container controller 12 or the slave container controller 14.

[0069] The change of the air composition can be used to indicate the occurrence of fire, etc. Of course, the above is only a possible example, and the specific type, model, function, communication connection object, etc. of the gas detection device 43, and the specific use of the air composition can be selected and determined according to the actual situation, and is not limited to the above.

[0070] Further, continue as Figure 3As shown, the master-slave battery management system can further include at least two temperature detection devices 44. Each of the at least two temperature detection devices 44 is arranged in a container body 31, and is in communication connection with the communication manager master 21 or the communication manager slave 22 in the container body 31.

[0071] For example, the number of temperature detection devices 44 can be equal to the number of container bodies 31, and the temperature detection devices 44 can be used for detecting the temperature in the container bodies 31, which can be real-time or periodic, for example, every 10 seconds or every 1 minute, etc. After detecting the temperature in the container body 31, the temperature detection device 44 can send the temperature value to the communication manager master 21 or the communication manager slave 22 through the communication connection. If the temperature value is sent to the communication manager slave 22, the communication manager slave 22 can further forward the temperature value to the communication manager master 21 through the communication connection.

[0072] In a possible solution, the temperature detection device 44 can also be in communication connection with the master container controller 12 or the slave container controller 14, and send the detected temperature value to the energy management system master 11 or the energy management system slave 13 through the master container controller 12 or the slave container controller 14.

[0073] When the temperature value is too high or too low, the communication manager master 21 can generate a control instruction to control the air conditioner or the like in the container body 31 with the too high or too low temperature value to start, so as to adjust the temperature in the container body 31.

[0074] Of course, the above is only a possible example, and the specific type, model, function, communication connection object of the temperature detection device 44, and the specific use of the temperature value can be selected and determined according to the actual situation, and are not limited to the above.

[0075] Figure 4 The master-slave battery management system structure schematic diagram provided by another embodiment of the application is shown in Figure 4 , the master-slave battery management system structure schematic diagram provided by another embodiment of the application is shown in Figure 1 On the basis of the embodiment, the energy storage converter 15 includes an energy storage converter master 151 and at least one energy storage converter slave 152.

[0076] The energy storage converter master 151 is connected with the master container controller 12, and the energy storage converter slave 152 is connected with the corresponding slave container controller 14.

[0077] Compared with the technical solution in which only one energy storage converter 15 is arranged, the arrangement of the energy storage converters can minimize the influence of the failure of the energy storage converter 15 on the overall system. Of course, the above content is only an example, and the specific purpose of the arrangement of the energy storage converters can be determined according to the actual situation, and is not limited to the above content.

[0078] It should be noted that the above Figures 1-4 The content shown is only a connection diagram, and does not represent the actual number and position relationship of the devices, and the actual number and position relationship of the devices can be selected and adjusted according to the actual situation.
