[0035] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments.

[0036] It should be noted that the terms "first", "second" and the like in the description and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0037] The embodiment of the present application provides a signal monitoring system. Figure 1 A structural schematic diagram of a signal monitoring system provided by the embodiment of the present application is shown in the figure. Figure 1 The signal monitoring system 10 comprises a battery management module 1, a power test module 2 and a control module 3. The battery management module 1 is used to connect the battery pack 4; the battery management module 1 comprises at least one output channel, and the output channel is connected between the battery management module 1 and the battery pack 4. The power test module 2 is connected with the battery management module 1, and is used to output a test signal to the battery management module 1. The control module 3 is connected with the battery management module 1 and the power test module 2, and the control module 3 is used to control the power test module 2 to output the test signal according to the test requirement, and to select the output channel as a target test channel. The battery management module 1 is used to generate a target electric signal according to the test signal, and to output the target electric signal through the target test channel. The control module 3 is further used to judge the fault state of the target test channel according to the target electric signal.
[0038] The battery pack 4 can be a flow battery. When the battery cell in the flow battery is working, the internal electrolyte on the negative electrode surface of the battery cell will be reduced to metallic zinc and deposited on the negative electrode due to zinc ions obtaining electrons, forming crystalline solid zinc, which affects the performance of the flow battery. By setting the battery management module 1, an electrical signal can be input to the flow battery, so that the crystalline solid zinc loses electrons and is oxidized to zinc ions and enters the electrolyte, thereby changing the zinc from a crystalline solid state to an ionic state to improve the performance and efficiency of the flow battery and ensure the reliable discharge process of the flow battery. The electrical signal can be a constant voltage and current signal.
[0039] The battery management module 1 can have multiple output channels, each of which can be connected to one battery pack 4, and each output channel is used to output an electrical signal to each battery pack 4 to improve the performance of each battery pack 4.
[0040] When each output channel in the battery management module 1 needs to be detected, the control module 3 controls the power test module 2 to output a test signal to the battery management module 1. At the same time, the control module 3 connects each output channel as a target test channel according to the test requirements, and the target test channel can output a target electrical signal according to the test signal.
[0041] For example, when the battery management module 1 has 30 output channels, the control module 3 controls the 30 output channels to be the target test channels and output the target electrical signal. The control module 3 can determine whether each output channel has a fault according to the data of the target electrical signal output by each target test channel.
[0042] For example, when the test signal output by the power test module 2 to the battery management module 1 is a voltage signal, the 30 output channels can divide the voltage signal and output a target electrical signal through the target test channel. In an ideal state, the calculated value of the target electrical signal is one-thirtieth of the voltage signal. When the actual value of the target electrical signal is within ±2% of the calculated value of the target electrical signal, the voltage output by the target test channel is in a stable state, otherwise the target test channel is in a fault state.
[0043] When the test signal output by the power test module 2 to the battery management module 1 is a current signal, in an ideal state, the target electrical signal output by the target test channel is the same size as the current signal. When the actual value of the target electrical signal is within ±2% of the current signal, the current output by the target test channel is in a stable state, otherwise the target test channel is in a fault state.
[0044] Through detection of the target electric signal of the output of the target test channel, when the voltage and the current are both stable, it indicates that the target test channel is qualified.
[0045] The technical scheme provided by the embodiment of the utility model, through setting power test module, can output test signal to battery management module, make battery management module can generate target electric signal according to this test signal, and output by target test channel, through the detection of control module to target electric signal, realized the fault judgment to target test channel, improved the reduction effect of internal crystallization, the utility model discloses simple structure realizes the fault detection of each output channel, and full -scale automatic test has good detection effect.
[0046] Continue to refer to Figure 1 On the basis of each embodiment described above, optionally, the battery management module 1 further includes an input channel, the power test module 2 is connected with the input channel of the battery management module 1, and the power test module 2 is used to transmit test signals to the input channel of the battery management module 1.
[0047] When the input channel of the battery management module 1 inputs the test signal, each output channel in the battery management module 1 can receive the test signal, but does not output the target electric signal. When the control module 3 selects the output channel as the target test channel, the battery management module 1 only outputs the target electric signal through the target test channel.
[0048] Through this setting mode, when the battery management module 1 receives the test signal, each output channel can output the target electric signal as the target test channel at any time. Further, the respective test of each output channel of the battery management module is realized, and the output speed of the target electric signal is faster and the detection effect is better.

Reference Figure 2 On the basis of each embodiment described above, optionally, the battery management module 1 further includes an input channel, the power test module 2 is connected with the input channel of the battery management module 1, and the power test module 2 is used to transmit test signals to the input channel of the battery management module 1.
[0050] The target electric signal output by the battery management module 1 can be collected by the collection unit 11, and the collection unit 11 can convert the target electric signal into a digital signal and input the digital signal into the control module 3, the control module 3 converts the digital signal into an actual value of the target electric signal according to the digital signal, and then judges the fault state of the target test channel. By arranging the collection unit 11, the collection and conversion of the target electric signal are realized, the control module 3 can detect and judge the target electric signal, and then the state detection of the target test channel is realized.
[0051] Figure 3 Another signal monitoring system structure schematic diagram provided by the embodiment of the utility model. Reference Figure 3 On the basis of each of the above embodiments, the control module 3 can optionally include: a control board card 31 connected with the power test module 2; the control board card 31 is used for generating a power control signal according to test requirements, and the power test module 2 outputs a test signal according to the power control signal. The control board card 31 is also used for generating a gate signal according to test requirements, and the battery management module 1 is used for selecting the output channel as the target test channel according to the gate signal.
[0052] The control board card 31 can be a PCBA (Printed Circuit Board Assembly), which is an assembly of a printed circuit board. The control board card 31 can be used to generate a power control signal and a gate signal according to test requirements and output them simultaneously. When the power test module 2 receives the power control signal, the power test module 2 outputs a test signal to the battery management module 1. When the battery management module 1 receives the gate signal, the battery management module 1 can control the target test channel to output a target electric signal according to the gate signal.
[0053] The utility model discloses a control board card is arranged, realized the control of battery management module and power test module, make the power test module can output test signal to battery management module, and output target electric signal through the target test channel of battery management module. The signal transmission has better transmission effect and faster transmission speed through the control board card, and has better controllability and stability.
[0054] Continue to refer to Figure 3 On the basis of each of the above embodiments, the control module 3 can optionally include: an upper computer 32 connected with the battery management module 1 and the control board card 31, and used for outputting a control signal according to test requirements. The control board card 31 is used for generating a power control signal and a gate signal according to the control signal.
[0055] Wherein, the host computer 32 is intended to represent various forms of digital computers, such as laptops, desktops, workstations, personal digital assistants, servers, blade servers, mainframes, and other appropriate computers.
[0056] The host computer 32 can be used to issue test instructions. When it is necessary to detect the fault of the output channel of the battery management module 1, the host computer 32 can generate a control signal according to the test requirement and input it into the control board card 31, so that the control board card 31 can generate a power control signal and a selection signal according to the control signal.
[0057] Continuing to refer to Figure 3 On the basis of the above embodiments, optionally, the control board card 31 comprises: a first channel 311 connected with the host computer 32, used for receiving the control signal. A second channel 312 connected with the power test module 2, used for transmitting the power control signal. A third channel 313 connected with the battery management module 1, used for transmitting the selection signal.
[0058] Wherein, the control board card 31 can comprise multiple channels, which has higher scalability. For example, the host computer 32 can be connected through the first channel 311; the power test module 2 can be connected through the second channel 312; the battery management module 1 can be connected through the third channel 313.
[0059] Exemplarily, the number of outgoing lines of the third channel 313 can be the same as the number of output channels of the battery management module 1. When the battery management module 1 has 30 output channels, 30 outgoing lines can be set correspondingly. This setting mode can improve the controllability of the control board card 31 to the battery management module 1, so that the selection of the target test channel is more accurate and efficient.
[0060] Continuing to refer to Figure 3 On the basis of the above embodiments, optionally, the power test module comprises: a first direct current power supply 21 connected with the battery management module 1 and the control board card 31, used for outputting a current test signal according to the power control signal. The acquisition unit is used for acquiring a target current signal, and the control module 3 is used for judging the fault state of the target test channel according to the target current signal.
[0061] Wherein, the first direct current power supply 21 can be used to output the current test signal. Exemplarily, when the current test signal is 10A and the battery management module 1 has 30 output channels, the target current signal output by each target test channel should also be 10A. Considering the factors such as line loss, a threshold range of ±2% can be set. That is, when the output target current signal is greater than 10.2A or less than 9.8A, it is judged that the target test channel is in a fault state. When the output target current signal is greater than 9.8A and less than 10.2A, it is judged that the target test channel is in a normal state.
[0062] With reference to Figure 3 On the basis of the above embodiments, optionally, the power supply test module further comprises: a second DC power supply 22 connected with the battery management module 1 and the control board 31, used for outputting a voltage test signal according to a power supply control signal. The acquisition unit is used for acquiring a target voltage signal, and the control module is used for judging the fault state of the target test channel according to the target voltage signal.
[0063] The second DC power supply 22 can be used to output the voltage test signal. Exemplarily, the second DC power supply 22 can output a voltage test signal of 45V or 60V.
[0064] When the voltage test signal is 45V and the battery management module 1 has 30 output channels, each output channel can divide the voltage of 45V, so the target voltage signal output by each target test channel should be 1.5V. After setting a threshold range of ±2%, when the output target voltage signal is greater than 1.53V or less than 1.47V, the target test channel is judged to be in a fault state. When the output target voltage signal is greater than 1.47V and less than 1.53V, the target test channel is judged to be in a normal state under the voltage test signal of 45V.
[0065] When the voltage test signal is 60V and the battery management module 1 has 30 output channels, each output channel can divide the voltage of 60V, so the target voltage signal output by each target test channel should be 2V. After setting a threshold range of ±2%, when the output target voltage signal is greater than 20.4V or less than 1.98V, the target test channel is judged to be in a fault state. When the output target voltage signal is greater than 1.98V and less than 20.4V, the target test channel is judged to be in a normal state under the voltage test signal of 60V.
[0066] When the target test channel is in a normal state under both the voltage test signal of 45V and the voltage test signal of 60V, the target test channel is determined to be in a normal state.
[0067] The second DC power supply provided by the utility model can output two voltage test signals of different sizes, and the state of the target test channel is judged according to the two voltage test signals of different sizes, so that the detection effect is good and the accuracy is high,
[0068] With reference to Figure 3 On the basis of the above embodiments, optionally, the battery management module 1 comprises at least two output channels, and the at least two output channels are connected with at least two battery groups in one-to-one correspondence; each output channel is sequentially used as a target test channel.

[0070] With reference to the foregoing Figure 3 On the basis of the foregoing embodiments, optionally, the signal monitoring system further comprises a power supply 5 connected with the battery management module 1 and used for providing working power for the battery management module 1.
[0071] The power supply 5 can be used for supplying power to the battery management module 1, and the power supply 5 can provide 24V power for the battery management module 1, so as to ensure the normal operation of the battery management module 1.
