Description

Technical Field

[0001] The present disclosure relates to a wireless communication system and a control method, and more particularly to a wireless communication system and a control method for a battery management system (BMS). Background Art

[0002] In order to measure the battery voltage, the current battery management system has many wires connected to the monitoring circuit board. After the voltage, temperature, etc. are measured by the chip on the circuit board, the information is sent to the upper-level management device or control substrate. However, complex wiring has an adverse effect on mass production costs, quality and reliability. Some automated battery management systems have been proposed. If automated measurement is to be performed, each battery cell has its own measurement circuit board to avoid complex wiring and transmit measurement information through wireless communication. However, the use of radio frequency (RF) wireless communication is prone to signal interference. In addition, if the node density of the battery cell is too high, they will interfere with each other and affect the reliability of the system. In order to solve the above problems, some battery management systems using daisy chain topology (daily chain) have been proposed. However, this point-to-point transmission method will cause higher latency.

[0003] Therefore, how to effectively apply wireless communication transmission technology to the battery management system and reduce latency is one of the issues to be solved in this case. Summary of the invention

This wireless communication system includes a control substrate and a plurality of energy storage devices. The control substrate is used to generate control information. Each of the plurality of energy storage devices includes an energy storage component and a node substrate. The node substrate is electrically connected to the energy storage component. The node substrate includes a first antenna circuit and a second antenna circuit. The first antenna circuit includes a first antenna unit and a second antenna unit disposed on opposite sides of the node substrate, and the second antenna circuit includes a third antenna unit and a fourth antenna unit disposed on opposite sides of the node substrate. The first antenna circuit is used to receive control information from an adjacent control substrate or a first adjacent antenna circuit of a first adjacent node substrate of a first adjacent one of the plurality of energy storage devices, wherein the second antenna circuit is used to transmit reply information generated based on the control information to an adjacent control substrate or a second adjacent antenna circuit of a first adjacent node substrate of a first adjacent one of the plurality of energy storage devices.

[0005] The present disclosure also proposes a control method. This control method is applicable to a wireless communication system including a control substrate, multiple node substrates and multiple components to be tested, wherein each of the multiple node substrates includes a first antenna circuit and a second antenna circuit, wherein the first antenna circuit includes a first antenna unit and a second antenna unit disposed on opposite sides of each of the multiple node substrates, and the second antenna circuit includes a third antenna unit and a fourth antenna unit disposed on opposite sides of each of the multiple node substrates, wherein the control method includes the following steps: generating control information by the control substrate; receiving control information by the first antenna circuit from an adjacent control substrate or a first adjacent antenna circuit of a first adjacent node substrate ...

[0070] Please refer to Figure 2 . In some embodiments, after receiving the control information, the antenna circuit 231A not only directly transmits the control information to the adjacent next node substrate 132B1 via the antenna unit 232A2, but the antenna unit 232A1 in the antenna circuit 231A also transmits the control information to the communication unit 234A and the control unit 236. After the control unit 236 receives the control information, the control unit 236 determines whether to perform a measurement operation or other operation based on the control information. In some embodiments, the measurement operation is performed by the measurement unit 238.

[0079] When the switch is connected to the low noise amplifier, the communication unit is used to receive control information. On the other hand, when the switch is connected to the up-mixer, the communication unit is used to send reply information.

[0080] For example, Figure 3 As shown, since the switch S3A is connected to the low noise amplifier L3A, the communication unit 234A is used to receive the control information from the antenna circuit 231A. On the other hand, since the switch S3B is connected to the up-mixer M3B2, the communication unit 234B is used to send the reply information to the antenna circuit 231B.

Figure 5 Only the node substrate 132A2 is presented as an example. Figure 5 The structure and operation of the node substrate 132A2 shown in the figure are also applicable to Figure 1 The node substrates 132B, 132C and Figure 4 Node substrate 132B2 in.

[0096] like Figure 5 As shown, in some embodiments, the node substrate 132A2 includes an antenna circuit 431A, an antenna circuit 431B, a switch S4A, a communication unit 434, a control unit 436, and a measuring unit 438. In terms of connection, the antenna circuit 431A is coupled to the switch S4A, the switch S4A is coupled to the communication unit 434, and the communication unit 434 is coupled to the control unit 436. The control unit 436 is coupled to the measuring unit 438, and the antenna circuit 431B is coupled to the switch S4A.

[0097] about Figure 5 The structure and operation of the antenna circuits 431A and 431B are similar to those of Figure 4 The antenna circuits 431A and 431B in FIG. 4 are similar and will not be described in detail here.

[0098] like Figure 5 As shown, the communication unit 434 includes a switch S5, a low noise amplifier L5, mixers M5A and M5B, an analog-to-digital converter ADC5, and a digital-to-analog converter DAC5. In terms of connection, the low noise amplifier L5 is coupled to the switch S5, the mixer M5A is coupled to the low noise amplifier L5, the analog-to-digital converter ADC5 is coupled to the mixer M5A, the mixer M5B is coupled to the switch S5, and the digital-to-analog converter DAC5 is coupled to the mixer M5B.

[0099] In some embodiments, mixer M5A is a down-conversion mixer, and mixer M5B is an up-conversion mixer.

[0100] In operation, when the communication unit 434 is used to receive control information, the terminals P41 and P43 of the switch S4A are connected, and the terminals P51 and P52 of the switch S5 are connected, so that the communication unit 434 receives the control information via the antenna circuit 431A. On the other hand, when the communication unit 434 is used to send reply information, the terminals P42 and P43 of the switch S4A are connected, and the terminals P51 and P53 of the switch S5 are connected, so that the communication unit 434 sends the reply information via the antenna circuit 431B.

[0101] See also Figure 6 . Figure 6 According to some embodiments of the present invention, Figure 1 Schematic diagram of the operation mode 600 of the wireless communication system 100 in FIG. Figure 6 As shown, in one embodiment, the control substrate 110 transmits control information CS6 to the node substrates 132A, 132B, and 132C at time point T0. In some embodiments, the control information CS6 includes an instruction to request the node substrate 132B to measure the voltage and to return the measured data at time point T1. The node substrates 132A, 132B, and 132C synchronously receive the control information CS6 sent by the control substrate 110 via the control channel. Since the control information CS6 only requests the node substrate 132B to measure the voltage, according to the control information CS6, the control units of the node substrates 132A and 132C do not perform the operation of measuring the voltage, and only the control unit of the node substrate 132B performs the operation of measuring the voltage.

[0102] Therefore, based on the control information CS6, after the measuring unit of the node substrate 132B measures the voltage value of the energy storage component 134B, the control unit of the node substrate 132B generates the reply information RS61 according to the voltage value obtained after the measuring unit of the node substrate 132B measures the energy storage component 134B.

[0103] After the reply message RS61 is generated, the communication unit of the node substrate 132B transmits the reply message RS61 to the control substrate 110 through the data channel at the time point T1.

[0104] See also Figure 7 . Figure 7 According to some embodiments of the present invention, Figure 1 Schematic diagram of another operation mode 700 of the wireless communication system 100 in FIG. Figure 7 As shown, in one embodiment, the control substrate 110 transmits control information CS7 to the node substrates 132A, 132B, and 132C at time point T0. In some embodiments, the control information CS7 includes instructions for requesting the node substrates 132A, 132B, and 132C to measure voltage and return the measurement data at time points T1, T2, and T3, respectively. Specifically, the control information CS7 includes instructions for the node substrate 132A to return a response message at time point T1 after measuring the voltage, for the node substrate 132B to return a response message at time point T2 after measuring the voltage, and for the node substrate 132C to return a response message at time point T3 after measuring the voltage.

[0105] The node substrates 132A, 132B and 132C synchronously receive the control information CS7 sent by the control substrate 110 via the control channel. Based on the control information CS7, the control unit of the node substrate 132A controls the measuring unit of the node substrate 132A to measure the voltage value of the energy storage component 134A. The control unit of the node substrate 132A generates a reply information RS71 according to the voltage value obtained after the measuring unit of the node substrate 132A measures the energy storage component 134A, and transmits the reply information RS71 to the control substrate 110 through the data channel at time point T1 based on the control information CS7.

[0106] Similarly, based on the control information CS7, after the control unit of the node substrate 132B controls the measuring unit of the node substrate 132B to measure the voltage value of the energy storage component 134B, the control unit of the node substrate 132B generates a response message RS72 according to the voltage value obtained after the measuring unit of the node substrate 132B measures the energy storage component 134B, and transmits the response message RS72 to the control substrate 110 through the data channel at time point T2 based on the control information CS7.

[0107] Similarly, based on the control information CS7, after the control unit of the node substrate 132C controls the measuring unit of the node substrate 132C to measure the voltage value of the energy storage component 134C, the control unit of the node substrate 132C generates a reply message RS73 according to the voltage value obtained after the measuring unit of the node substrate 132C measures the energy storage component 134C, and transmits the reply message RS73 to the control substrate 110 through the data channel at time point T3 based on the control information CS7.

[0108] Although the reply messages RS71 to RS73 are all transmitted to the control substrate 110 via the data channel, based on the control message CS7, the reply messages RS71 to RS73 are transmitted in the data channel at different time points, thereby avoiding the problem of mutual interference between the reply messages.

[0109] See also Figure 8 . Figure 8 A top view 100C of another wireless communication system 100 is shown according to some embodiments of the present invention. Figure 8 A top view 100C of the wireless communication system 100 and Figure 2 The difference between the top view 100A of the wireless communication system 100 in FIG. 1 is that the configuration of the node substrate 132B1 in the top view 100C is that the node substrate 132B1 in the top view 100A is rotated 180 degrees on the XY plane.

[0110] That is to say, in the implementation of the present case, the node substrate can be flexibly placed and can still form a control channel and a data channel to transmit control information and reply information.

[0111] See also Fig. 9 . Fig. 9 A flow chart of a control method 900 is shown according to some embodiments of the present invention. Fig. 9 The control method 900 is applicable to Figure 1 , Figure 2 , Figure 4 and Figure 8 The wireless communication system shown in FIG. Fig. 9 As shown, the control method 900 includes steps S910 to 930. In step S910, control information is generated by the control substrate. In step S920, the first antenna circuit receives the control information from the first adjacent antenna circuit of the adjacent control substrate or the first adjacent node substrate of the first adjacent node substrate among the plurality of node substrates. In step S930, the second antenna circuit transmits the response information generated based on the control information to the second adjacent antenna circuit of the adjacent control substrate or the first adjacent node substrate of the first adjacent node substrate among the plurality of node substrates. The detailed operation method of the control method 900 is the same as that described above corresponding to Figures 1 to 8 The operation method is similar to that described in , and will not be described in detail here.

[0112] In summary, the disclosed embodiments provide a wireless communication system and control method. When the antenna circuit on the node substrate receives an uplink (e.g., reply information) or downlink (e.g., control information) signal, in addition to transmitting the signal or information to the communication unit and control unit on this node substrate, the signal or information is also directly sent to the node substrate of the next station through a signal amplifier or a signal retransmission device and an antenna unit. When the node substrate transmits the signal or information directly to the next adjacent node substrate, it does not pass through the communication unit and control unit of this node substrate, thereby achieving the purpose of low-latency signal or information transmission.

[0113] In addition, in the implementation of the present case, the wireless communication system can be composed of a controller and multiple energy storage devices. After the energy storage devices are placed in series (either forward or reverse, not limited to a fixed direction), an uplink and downlink wireless communication network (including a control channel and a data channel) is automatically formed. The controller can send instructions (such as control information) via the uplink and downlink wireless communication networks, and receive the measurement values ​​(such as reply information) sent back by the energy storage device. In summary, in the implementation of the present case, a set of radio frequency wireless communication architecture is designed, and a strong wave (transmission) component (such as a signal amplifier or a signal retransmission device) and an antenna are designed on the node substrate (i.e., the battery measurement communication board). After multiple node substrates and the control substrate are placed in series, the signal or information is transmitted to all node substrates through the near-field network communication technology and the signal strong wave (transmission) component, realizing a wireless broadcast communication architecture with low labor, low interference, low latency, and highly flexible combination.
