In the existing charging and discharging operation of the battery, a charging circuit and a discharging circuit are used to realize the charging and discharging operation of the battery. When charging, the main control chip sends a signal to turn on the charging circuit and the battery to realize the charging operation of the battery.

[0003] At present, in the discharging process, the direct current in the battery is converted into alternating current by an inverter module and fed back to the power grid. In the charging process, the alternating current of the power grid is converted into direct current by the inverter module to realize the charging operation of the battery. However, the inverter has its own power consumption and heat generation during operation.

DETAILED DESCRIPTION

[0035] The application will be further described in connection with the embodiments illustrated in the accompanying drawings.

[0036] With reference to Figures 1-4 To achieve the above object, the application provides the following technical scheme: an intelligent storage battery remote charging and discharging feedback type control cabinet, comprising a control cabinet body, a control mainboard 1 arranged in the control cabinet body, a serial port server 2 electrically connected with the control mainboard 1, a battery parameter measuring instrument for measuring parameters of a storage battery group in the control cabinet body, a mains power acquisition device for detecting the working state of mains power, and a feedback type power module 5 for charging and discharging the storage battery group. The serial port server 2 is further in communication connection with a central remote control platform 6 to receive a maintenance instruction sent by the central remote control platform 6 and forward the maintenance instruction to the control mainboard 1. When a staff needs to remotely maintain and detect the storage battery group, the staff can interact with the central remote control platform 6, the central remote control platform 6 sends a maintenance command to the serial port server 2, the serial port server 2 can be connected with multiple liquid crystal control terminals 7, so that multiple storage battery groups equipped with remote charging and discharging systems can be controlled uniformly by one serial port server 2, and the staff can conveniently control the multiple storage battery groups equipped with remote charging and discharging systems. The serial port server 2 forwards the maintenance command to the control mainboard 1, the control mainboard 1 controls the feedback type power module 5 to perform charging and discharging operation.

[0037] The battery parameter measuring instrument, the mains power acquisition device and the feedback power module 5 are electrically connected with the control mainboard 1, and the feedback power module 5 is further connected with external mains power to obtain power supply and feedback current; when the control mainboard 1 receives a maintenance instruction, the switch in the feedback power module 5 is controlled to turn on and off, and then the charging and discharging states of the feedback power module 5 are switched; when the control mainboard 1 receives mains power state information indicating that the mains power state is abnormal, the control mainboard 1 controls the feedback power module 5 to interrupt charging or discharging; when the control mainboard 1 receives battery parameter information indicating that the charging of the battery pack is completed, the control mainboard 1 controls the feedback power module 5 to interrupt the charging operation; during the charging process of the battery pack, the mains power acquisition device further detects mains power state information of external mains power, and the mains power acquisition device uses an existing C2000 A2-SDD6060-CAX mains power on-off state detector to conveniently detect whether the mains power is disconnected, and simultaneously sends the mains power state information to the control mainboard 1; the control mainboard 1 sends the mains power state information to the central remote control platform 6 through the serial server 2, so that the working staff can conveniently check the working state of the external mains power in real time; the battery parameter measuring instrument sends the detected battery parameter information to the control mainboard 1, wherein the control mainboard 1 is a circuit mainboard composed of an existing main control chip, a wireless communication chip and peripheral circuits thereof; the control mainboard 1 is provided with a parameter threshold value, and when the battery parameter information received by the control mainboard 1 exceeds the parameter threshold value, the control mainboard 1 controls the feedback power module 5 to stop charging the battery pack.

[0038] The feedback power module 5 includes a discharging load 51 for discharging operation of the battery and a bidirectional inverter module 52 for inverting operation of the current, so that the battery parameter measuring instrument detects the residual power of the battery pack and feeds back to the control mainboard 1, and the control mainboard 1 controls the feedback power module 5 to perform discharging operation or inverting operation. The control mainboard 1 has the following standards for the residual power: 1. the power at the intersection of the power consumption curve and the power generation curve of the bidirectional inverting module 52 mentioned below is the standard, and the power at the intersection of the power consumption curve and the power generation curve means that the power fed back to the power grid by the bidirectional inverting module 52 is consistent with the power consumed by itself, when the power is lower than the power at the intersection, the power consumption of the bidirectional inverting module 52 is greater than the power converted, at this time, if inverting conversion discharging is performed, it is actually a loss in energy conversion, which does not conform to the actual production benefit; 2. the power consumption curve and the power generation curve of the bidirectional inverting module 52 and the total heat generation of the discharging load 51 and the stage heat generation of the bidirectional inverting module 52 in different stages are mentioned below, and the user analyzes the power consumption, power conversion and heat generation, etc. to set the detection standard by himself. The bidirectional inverting module 52 can select the appropriate discharging path through the current in the battery to achieve the best energy consumption selection, which not only can reasonably protect the circuit and electrical components, but also can relatively select the lowest energy consumption to protect the interests of the company.

[0039] The regenerative power module 5 also includes an inverter detection and storage module 53, used to detect the real-time power consumption of the bidirectional inverter module 52 and the real-time conversion of the battery DC power to AC power, generating and storing power consumption curves and power generation curves; this inverter detection and storage module uses the real-time power consumption of the bidirectional inverter module 52 to create a power consumption curve, and the real-time conversion of the battery DC power to AC power to create a power generation curve, such as... Figure 4 As shown, the x-axis of the power generation curve and the y-axis of the power consumption curve represent time, the y-axis represents current, and Q represents the intersection point. This graph allows users to intuitively see the relationship between power generation and power consumption.

[0040] The inverter detection and storage module 53 is electrically connected to the control motherboard 1. The power consumption curve and power generation curve of the previous discharge inverter operation stored in the inverter detection and storage module 53 at the intersection point are used as the selection criteria for the control motherboard 1 to perform discharge or inverter operations in the next discharge operation. The power consumption curve and power generation curve of the bidirectional inverter module 52 at the intersection point are used as the standard. The significance of the power consumption curve and power generation curve at the intersection point is as follows: at this time, the power fed back to the grid by the bidirectional inverter module 52 is consistent with the power consumed by itself. When the power is lower than the power at the intersection point, the power consumption of the bidirectional inverter module 52 is greater than the power converted. If inverter conversion and discharge are performed at this time, it is actually a loss from the perspective of energy conversion, which is not in line with the actual production efficiency. When the power is higher than the power at the intersection point, the power consumption of the bidirectional inverter module 52 is less than the power converted, which is in line with the actual efficiency. In addition, the power consumption and conversion output of the bidirectional inverter module 52 will be affected by many factors such as the usage time of the bidirectional inverter module 52, the temperature of the computer room, and the region. Therefore, by using the intersection point of the power consumption curve and power generation curve of the previous discharge operation stored in the inverter detection and storage module as the detection standard of the control motherboard 1 in the next discharge operation, the detection standard is frequently and automatically updated, so as to achieve the most ideal energy-saving state without the need for human operation.

[0041] The regenerative power module 5 also includes a temperature detection module 54, used to detect the total heat generation of the discharge load 51 and the stage-specific heat generation of the bidirectional inverter module 52 at different stages. The temperature detection module 54 is designed to detect the heat generation of the load discharge and the bidirectional inverter module 52. Combined with the power consumption curve and power generation curve, this allows users to intuitively and clearly understand the various conditions at different times and determine whether to prioritize low heat generation or low power consumption based on actual needs, thus enabling the user to make the most suitable choice.

[0042] The control cabinet is equipped with an LCD control terminal 7, which is used to display the power consumption curve and power generation curve, the total heat generation of the discharge load 51 and the staged heat generation of the bidirectional inverter module 52 at different stages, as well as the detection parameters of the battery parameter measuring instrument and the mains power acquisition device. The LCD control terminal 7 facilitates on-site control by staff, while the cooperation between the central remote control platform 6 and the LCD control terminal 7 facilitates remote maintenance and testing by staff.

[0043] The LCD control terminal 7 includes a setting module 71, used for manually setting the selection criteria for the feedback power module 5 to perform discharge or inverter operations. The setting module 71 is also used for manually setting detection standards. Users can manually set the optimal and most practical method based on the obtained data, resulting in a more user-friendly design.

[0044] The battery pack includes a first battery pack 11 and a second battery pack 12. Both the first battery pack 11 and the second battery pack 12 are electrically connected to the regenerative power module 5. The regenerative power module 5 controls the charging and discharging of the first battery pack 11 and the second battery pack 12. The battery parameter measuring instrument includes a first battery parameter measuring instrument 31 and a second battery parameter measuring instrument 32. Both the first battery parameter measuring instrument 31 and the second battery parameter measuring instrument 32 are electrically connected to the control motherboard 1, and are also electrically connected to the first battery pack 11 and the second battery pack 12, respectively.

[0045] Control motherboard 1 includes:

[0046] Normally closed switch ZY1, one end of which is coupled to the first mains power supply, and the other end is coupled to the first battery pack 11 and the first discharge switch WH1;

[0047] Normally open switch BY1, one end of which is coupled to one end of diode D3, and the other end is coupled to the second battery pack 12;

[0048] Diode D3 is coupled between normally closed switch ZY1 and normally open switch BY1.

[0049] Normally closed switch ZY2, one end of which is coupled to the second mains power supply, and the other end is coupled to the second battery pack 12 and the second discharge switch WH2;

[0050] Normally open switch BY2, one end of which is coupled to one end of diode D4, and the other end is coupled to the first battery pack 11;

[0051] Diode D4 is coupled between normally closed switch ZY2 and normally open switch BY2;

[0052] One end of the second discharge switch WH2 is coupled to the feedback power module 5, and the other end is connected to the normally closed switch ZY2 and the normally open switch BY1 to connect or disconnect the connection between the feedback power module 5, the second mains power supply and the first battery pack 11, so as to control whether to discharge the first battery pack 11.

[0053] One end of the first discharge switch WH1 is coupled to the regenerative power module 5, and the other end is connected to the normally closed switch ZY1 and the normally open switch BY2 to connect or disconnect the connection between the regenerative power module 5, the first mains power supply and the second battery pack 12, so as to control whether the second battery pack 12 is discharged.

[0054] Through the above technical solution, when the first mains power is interrupted, the first battery pack 11 can transmit power to the electrical equipment through the first mains power line via switch ZY1. At this time, the power supply can be switched from the first mains power supply to the first battery pack 11. With the setting of the feedback power module 5, the first battery pack 11 can also be float-charged when the first mains power is available. In this embodiment, the first battery pack 11 can be in the states of discharging, waiting to be charged, and charging, while the second battery pack 12 is discharging, waiting to be charged, and charging, under different on / off states of various switches. When the control motherboard 1 receives the maintenance command, it can parse the switch code corresponding to the closing or opening of different switches. At this time, the main control motherboard can control the switch according to the switch code. Different switch opening and closing causes the first battery pack 11 and the second battery pack 12 to switch between different operating states. The second battery pack 12 can symmetrically operate the corresponding switch according to the distance of the first battery pack 11's operating state, thereby switching the operating state of the second battery pack 12. In this way, the operator only needs to send a maintenance preset command with switch code to enable the control board 1 to perform automated operation, without the need for the operator to remotely control the switches one by one. This also avoids damage to the first battery pack 11 or the second battery pack 12 due to improper operation sequence during remote control and avoids adverse effects on the mains power. The diodes D3 and D4 can isolate the first mains power and the second mains power to prevent mutual collision or interference.

[0055] The regenerative power module 5 includes:

[0056] A load switch, one end of which is coupled to the node of the first discharge switch WH1 and the second discharge switch WH2, and the other end is coupled to the discharge load 51, is used to control whether to perform a discharge operation.

[0057] An inverter switch is provided, with one end coupled to the node of the first discharge switch WH1 and the second discharge switch WH2, and the other end coupled to the bidirectional inverter module 52, for controlling whether to perform discharge inverter operation.

[0058] A mains switch, one end of which is coupled to an external mains power supply and the other end is coupled to a bidirectional inverter module 52, is used to control whether to perform regenerative discharge or charging operations.

[0059] The main control board 1 controls the load switch and the inverter switch to close selectively, and the mains switch closes simultaneously when the inverter switch closes.

[0060] Through the above technical solution, when the remaining power of the battery pack is less than the selection standard of the control motherboard 1, the load switch is closed, causing the current in the battery pack to flow to the discharge load 51 for discharge operation; when the remaining power of the battery pack is greater than the selection standard of the control motherboard 1, the inverter switch and the mains switch are closed, causing the current in the battery pack to flow to the bidirectional inverter module 52 for inverter operation and then fed back to the mains power.

[0061] The mains power acquisition device includes a first mains power acquisition unit 41 and a second mains power acquisition unit 42, both electrically connected to the control main board 1. The first mains power acquisition unit 41 and the second mains power acquisition unit 42 are respectively connected to an external first mains power supply and a second mains power supply to detect the operating status of the two mains power supplies. The use of two mains power acquisition units (41 and 42) to acquire data from both mains power supplies increases the accuracy of mains power monitoring and facilitates simultaneous monitoring of both mains power supplies, allowing staff to easily determine their operating status and facilitating subsequent testing and operation.

[0062] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
