Description

Wireless Management System

The present disclosure relates to a wireless management system and method, and more particularly to a wireless management system and method for managing energy storage units.

In order to measure the voltage, current, temperature and other data of the energy storage device, the current battery management system (BMS) needs to lay many wires between the management end device and the energy storage device so that the management end device can directly measure the status of each energy storage device.

However, since each energy storage device needs to be equipped with corresponding connecting wires to the management end device, when the number of energy storage devices is large, the number of connecting wires required to connect to the management end device is also large. The complex connecting wires may bring many dangers to the energy storage device (for example: short circuit), and also increase the risk of wire pulling and installation. In addition, the complex connecting wires will increase the cost of the product, making it difficult to maintain quality and reliability. Therefore, the method of managing energy storage devices using wireless communication technology provides a new solution.

In the prior art, when wireless communication technology is used to manage energy storage devices, if optical communication technology is used, signal loss is likely to occur.

In view of this, providing optical communication wireless management technology solutions for managing energy storage units is a goal that the industry urgently needs to work on.

In order to solve the above problems, the present disclosure proposes a wireless management system, including a controller and a first energy storage unit. The controller includes a first transceiver, and the first transceiver is used to transmit or receive at least one optical signal to perform a management operation. The first energy storage unit includes a substrate, an energy storage device and a light-guiding element. The substrate has a first surface and a second surface, wherein the first surface of the substrate is provided with a second transceiver. The energy storage device is coupled to the second surface of the substrate. The light-guiding element has a first surface and a second surface. A first optical signal transmitted by the first transceiver of the controller passes through the light-guiding element of the first energy storage unit to the second transceiver of the first energy storage unit.

The present disclosure also provides a wireless management system, comprising a controller, a plurality of energy storage units and a light-guiding element. The controller comprises a first transceiver, which is used to transmit or receive at least one optical signal to perform a management operation. Each of the energy storage units comprises a substrate and an energy storage device. The substrate has a first surface and a second surface, wherein a second transceiver is provided on the first surface of the substrate. The energy storage device is coupled to the second surface of the substrate. The light-guiding element has a first surface and a second surface. A first optical signal transmitted by the first transceiver of the controller passes through the light-guiding element to the second transceiver of each of the energy storage units.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are intended to provide further explanation of the disclosure as claimed.

In order to make the description of the present disclosure more detailed and complete, reference may be made to the attached drawings and various embodiments described below, in which the same numbers in the drawings represent the same or similar elements.

Please refer to Figure 1, which is a schematic diagram of the wireless management system 1 in the first embodiment of the present disclosure. The wireless management system 1 includes a controller C1 and energy storage units E1, E2, E3 and E4. The controller C1 includes a transceiver TC1.

The energy storage units E1, E2, E3 and E4 in the wireless management system 1 have the same structure and function. In other words, the substrates B1, B2, B3 and B4 have the same structure and function, the light-guiding elements L1, L2, L3 and L4 have the same structure and function, and the energy storage devices D1, D2, D3 and D4 have the same structure and function.

It should be noted that the number of energy storage units in the wireless management system 1 shown in FIG. 1 is only used as an example, and the wireless management system may actually include other numbers of energy storage units.

As shown in FIG1 , the light guide elements L1 , L2 , L3 and L4 are in the shape of long strips, and one end of each of the light guide elements L1 , L2 , L3 and L4 is disposed toward the transceiver TC1 of the controller C1 . It should be noted that the light guide elements L1 , L2 , L3 and L4 are not limited to the shapes shown in FIG1 .

In some embodiments, each of the energy storage devices D1, D2, D3, and D4 includes a lithium battery, a lead-acid battery, and/or other devices having the function of storing energy.

Further, please refer to FIG. 3 for the structure of substrates B1, B2, B3 and B4, which is a schematic diagram of substrate B in the first embodiment of the present disclosure. Substrate B is an example of substrates B1, B2, B3 and B4 in the wireless management system 1 shown in FIG. 1. Substrate B includes a transceiver T and a sensor R, wherein the transceiver T is coupled to the sensor R. In some embodiments, substrate B includes a printed circuit board (PCB).

In some embodiments, the substrate B is coupled to an energy storage device (e.g., energy storage devices D1, D2, D3, and D4), and the sensor R is used to measure the operating state of the energy storage device to obtain state information. For example, the sensor R may include a voltmeter, an ammeter, a resistance meter, and/or a thermometer, which are respectively used to measure the voltage, current, resistance, and/or temperature values (i.e., state information) of the energy storage device.

For ease of understanding, please refer to FIG. 2 for one of the ways of connecting the energy storage devices in series and coupling the substrate and the energy storage device. As shown in FIG. 2, in some embodiments, energy storage devices D1, D2, D3, and D4 are connected in series by a bus bar BB, wherein the positive and negative poles of two adjacent energy storage devices among the energy storage devices D1, D2, D3, and D4 are alternately arranged, the positive pole of the energy storage device D1 is electrically connected to the negative pole of the energy storage device D2 through the bus bar BB, the positive pole of the energy storage device D2 is electrically connected to the negative pole of the energy storage device D3 through the bus bar BB, and the positive pole of the energy storage device D3 is electrically connected to the negative pole of the energy storage device D4 through the bus bar BB. In addition, the positive electrode and the negative electrode of the energy storage device are coupled to the surface of the corresponding substrate through a strip tab ST having a conductive material so that the substrate can measure the energy storage device.

In some embodiments, the transceiver TC1 and the transceiver T are optical signal transceivers (eg, infrared transceivers) for sending and receiving optical signals (eg, infrared signals).

Correspondingly, the light guide elements L1, L2, L3 and L4 can be made of light-transmissive (eg, infrared light-transmitting) materials such as silicone, polycarbonate (PC), acrylic (PMMA), etc., to transmit the optical signal (eg, infrared light signal) transmitted by the transceiver TC1 and/or the transceiver T.

In some embodiments, the transceiver TC1 is used to transmit or receive optical signals to perform management operations, whereby the wireless management system 1 can monitor and manage the energy storage units E1, E2, E3 and E4 through the controller C1, for example, measuring and obtaining the operating data of the energy storage device such as voltage, current, resistance, temperature, etc.

Specifically, the transceiver TC1 of the controller C1 can transmit control signals to the energy storage units E1, E2, E3 and E4, wherein the control signals are used to instruct the substrates B1, B2, B3 and B4 of the energy storage units E1, E2, E3 and E4 to respectively measure the energy storage devices D1, D2, D3 and D4 to generate status information, and the status information may include information measured by the sensor R, for example: the voltage, current, resistance and/or temperature of the energy storage devices D1, D2, D3 and D4.

In some embodiments, the substrate B may further include a microcontroller (not shown in the figure), the microcontroller is coupled to the transceiver T and the sensor R, and after the sensor R converts various status information into digital signals, the microcontroller stores the digital signals and can send the digital signals out through the transceiver T. In addition, the microcontroller can also receive instructions, such as starting measurement, starting to send information, sleeping, waking up, time correction, synchronous measurement, starting/stopping a battery balancing circuit, starting to measure electrochemical impedance spectroscopy (EIS) function, etc.

Furthermore, after the substrates B1, B2, B3 and B4 respectively sense the energy storage devices D1, D2, D3 and D4 and generate status information, the substrates B1, B2, B3 and B4 can respectively use the transceiver T to transmit status signals to the controller C1, wherein the status signals include the aforementioned status information. The aforementioned control signal and/or status signal can be transmitted through optical signals between the controller C1, the energy storage units E1, E2, E3 and E4. As for the structure of the light-guiding element and how the wireless management system 1 transmits the optical signal, please refer to FIG. 4, which is a cross-sectional view of the wireless management system 1 in the first embodiment of the present disclosure. As shown in FIG. 4, the light-guiding element L1 is disposed on a surface of the substrate B1 on which the transceiver T1 is disposed, and is disposed corresponding to the transceiver T1 of the substrate B1. In this way, the optical signal transmitted by the transceiver T1 can enter the light guide element L1. Similarly, the light guide elements L2, L3 and L4 and the substrates B2, B3 and B4 in the energy storage units E2, E3 and E4 are also arranged in the same manner.

As shown in FIG. 4 , a surface of the light guide element L1 opposite to the transceiver T1 has a pattern P11, and the pattern P11 may be a groove on the surface of the light guide element L1, and when the optical signal transmitted by the transceiver T1 is transmitted to the surface of the light guide element L1 located at the pattern P11 via the paths S1 and S2, the optical signal will be totally reflected and transmitted toward the two ends of the light guide element L1, wherein the optical signal on the path S1 is reflected to the end facing the transceiver TC1, and the optical signal on the path S2 is reflected to the end facing the light guide element L2. It should be noted that the optical signals on the paths S1 and S2 may be optical signals transmitted by the transceiver T1 once, and the light rays on different paths after the optical signal is transmitted are reflected to different directions when they contact the surface of the pattern P11 due to the different transmission paths. In this way, the optical signal on the path S1 can be transmitted to the transceiver TC1 and then received by the transceiver TC1, and the optical signal on the path S2 can be transmitted to one end of the light guide element L1.

In contrast, after the optical signals transmitted by other transceivers (e.g., the optical signals on path S3) are transmitted from the two ends of the light guide element L1 and enter the light guide element L1, when the optical signals are transmitted to the surface of the light guide element L1 located at the pattern P11, part of the light will be reflected along path S2 and transmitted to the transceiver T1, so that the transceiver T1 receives the optical signals. In this way, the optical signals originally transmitted to the two ends of the light guide element can be reflected to the transceiver above, for example, the optical signals on path S2 can be reflected by the patterns of the light guide elements L2, L3 and L4 to the transceivers T2, T3 and T4, respectively, so that the transceivers T2, T3 and T4 receive the optical signals.

Similarly, the optical signal transmitted by the transceiver TC1 may enter from one end of the light guide element and be reflected by the patterns of the light guide elements L1, L2, L3 and L4 to the transceivers T1, T2, T3 and T4 respectively, so that the transceivers T1, T2, T3 and T4 receive the optical signal.

Furthermore, a surface of the light-guiding element L1 corresponding to the transceiver T1 may also have a pattern P12. As shown in FIG. 4 , the pattern P12 may be a curved surface similar to a convex lens on the surface of the light-guiding element L1. Thus, when the optical signal transmitted by the transceiver T1 contacts the surface of the light-guiding element L1 located at the pattern P12 along the paths S1 and S2, the optical signal will be refracted and focused, so that the light can be transmitted to a specific location (for example, pattern P11) in a more concentrated manner, thereby making the optical signal intensity received by other transceivers higher.

It should be noted that the pattern on the light guide element may be located within the transmission range of the optical signal transmitted by the transceiver as shown in Fig. 4. However, in other embodiments, the pattern on the light guide element may also be distributed over the entire surface of the light guide element.

On the other hand, since the energy storage units E1, E2, E3 and E4 can be separately installed in the wireless management system 1 in a modular manner, as shown in FIG. 4 , there is a gap G between the light guide elements L1 and L2, which are installed separately without bonding or fixing. However, when the optical signal is transmitted from the light guide element L2 to the light guide element L1 along the path S3, it can still pass through the gap G and be transmitted to the light guide element L1.

It should be noted that when an optical signal is transmitted in a light-guiding element or in a gap between light-guiding elements, even if some light is scattered and the intensity is attenuated, making the intensity of the optical signal received by the transceiver weaker (for example, the intensity of the input optical signal received by the energy storage unit is only 8% of the original intensity of the optical signal), the transceiver of the controller or the transceiver of the energy storage unit can still receive the attenuated optical signal and interpret the information carried by the optical signal. In other words, the signal transmitted by the controller or the energy storage unit can still be recognized by the controller or the energy storage unit even if it passes through the gap.

Please further refer to FIG. 5, which is a cross-sectional view of the wireless management system 1 in the first embodiment of the present disclosure, wherein the light guide element L1 shown in FIG. 5 has another pattern P13. As shown in FIG. 5, the pattern P13 can be a microstructure or sawtooth groove on the surface of the light guide element L1 on the side opposite to the transceiver T1. Similar to the pattern P11, the pattern P13 can reflect the optical signal transmitted by the transceiver T1 and then transmit it to the two ends of the light guide element L1.

It should be noted that the aforementioned embodiment uses the light guide element L1 as an example. In fact, the light guide elements L1, L2, L3 and L4 also have the same or similar patterns so that the optical signals transmitted by the corresponding transceivers T1, T2, T3 and T4 can be transmitted toward the two ends of the light guide elements L1, L2, L3 and L4.

In some embodiments, patterns P11, P12 and P13 may be composed of the surface shape structure of the light-guiding element itself. However, in other embodiments, the light-guiding element may be made of a soft and plastic material (e.g., silicone), and the energy storage device has a shape corresponding to the pattern on the side surface that contacts the light-guiding element (e.g., the sawtooth shape of pattern P13 in FIG. 5). In this way, when the light-guiding element is pressed onto the surface of the energy storage device, the light-guiding element may form patterns P11 or P13 as shown in FIG. 4 or 5. In some embodiments, patterns P11, P12 and P13 may also be formed by patches attached to the surface of the light-guiding element, wherein the patches have corresponding microstructure patterns.

It should be noted that the paths shown in FIG. 4 and FIG. 5 (for example, paths S1, S2, and S3) are examples of partial light transmission paths in optical signals. In practice, after the transceiver of the controller or energy storage unit transmits an optical signal, the optical signal will be transmitted in the light-guiding element, and reflection, diffraction, refraction, etc. will occur at the same time. However, through the placement of the light-guiding element and the design of the pattern, the optical signal can be transmitted between the controller and the energy storage unit through the light-guiding element, and the intensity of the optical signal received by the transceiver of the controller and the energy storage unit is still sufficient for the controller or the energy storage unit to interpret the information carried by the optical signal.

For the paths of the optical signals transmitted in the light-guiding elements of the wireless management system 1, please refer to Figures 6 and 7. Figure 6 is a schematic diagram of the optical signal path S5 between the transceiver T1 and the transceiver TC1. Figure 7 is a schematic diagram of the optical signal path S6 between the transceiver T2 and the transceiver TC1. As shown in Figures 6 and 7, the optical signal transmitted by the transceiver TC1, part of which can be transmitted along the path S5 to the transceiver T1 and along the path S6 to the transceiver T2. Conversely, the optical signal transmitted by the transceiver T1, part of which can be transmitted along the path S5 to the transceiver TC1, and the optical signal transmitted by the transceiver T2, part of which can be transmitted along the path S6 to the transceiver TC1.

Further, please refer to FIG. 8, which is a schematic diagram of the transmission of optical signals between the controller C1 and the substrates B1 and B2 in the first embodiment of the present disclosure. As shown in FIG. 8, the optical signal transmitted by the transceiver TC1 of the controller C1 can be transmitted to the transceiver T1 of the substrate B1 through the light-guiding element L1; conversely, the optical signal transmitted by the transceiver T1 can also be transmitted to the transceiver TC1 through the light-guiding element L1. On the other hand, the optical signal transmitted by the transceiver TC1 can also be transmitted to the transceiver T2 of the substrate B2 through the light-guiding element L1, the gap G, and the light-guiding element L2 in sequence; conversely, the optical signal transmitted by the transceiver T2 can be transmitted to the transceiver TC1 through the light-guiding element L2, the gap G, and the light-guiding element L1 in sequence. Furthermore, the optical signal transmitted by the transceiver T1 can also be transmitted to the transceiver T2 through the light guide element L1, the gap G and the light guide element L2 in sequence; conversely, the optical signal transmitted by the transceiver T2 can also be transmitted to the transceiver T1 through the light guide element L2, the gap G and the light guide element L1 in sequence. In some embodiments, due to reasons such as the installation method, there is also a gap between the transceiver TC1 and the light guide element L1.

It should be noted that when the optical signal passes through the gap G or the gap between the transceiver TC1 and the light-guiding element L1, although some light will leak out and the intensity will be reduced, the optical signal can still be maintained at an intensity that the transceiver can receive and interpret its content when the width of the gap is within a reasonable range. In addition, if the energy storage unit or energy storage system fails and smoke enters the gap to block the light, the optical signal will be blocked and communication will fail. In other words, if communication failure occurs, it may mean that the energy storage unit or energy storage system has failed, so the gap described in the present disclosure can be used for a smoke detection mechanism.

In some embodiments, after the optical signal is transmitted by transceiver TC1, a portion of the optical signal is transmitted to transceiver T1 along the aforementioned path, and another portion of the optical signal is also transmitted to transceiver T2 along the aforementioned path. In other words, the optical signal transmitted by transceiver TC1 can be received by transceivers T1 and T2 at the same time. Similarly, the optical signal transmitted by transceiver T1 can also be received by transceivers TC1 and T2 at the same time, and the optical signal transmitted by transceiver T2 can also be received by transceivers TC1 and T1 at the same time.

It should be noted that for ease of explanation, FIG. 8 uses controller C1, substrates B1 and B2 as examples. In fact, the wireless management system may include other numbers of controllers and/or substrates, and the optical signals transmitted by the transceivers of the controllers and/or substrates may be received by the transceivers of other controllers and/or substrates at the same time.

According to the first embodiment, the controller C1 and the energy storage units E1, E2, E3 and E4 of the wireless management system 1 can transmit optical signals through the light guide elements L1, L2, L3 and L4. In this way, the controller C1 can transmit control signals to the energy storage units E1, E2, E3 and E4 to instruct the substrates B1, B2, B3 and B4 to measure the operating status of the energy storage devices D1, D2, D3 and D4, and the substrates B1, B2, B3 and B4 can transmit the status information obtained after the measurement to the controller C1, thereby achieving the technical purpose of managing the energy storage devices D1, D2, D3 and D4.

Regarding another embodiment of the present disclosure, please refer to FIG. 9, which is a schematic diagram of a wireless management system 2 in a second embodiment of the present disclosure. The wireless management system 2 includes a controller C2, energy storage units E5, E6 and E7, and a light-guiding element L. The controller C2 includes a transceiver TC2, wherein the structure and function of the controller C2 are the same as those of the controller C1 in the first embodiment. The energy storage unit E5 includes a substrate B5 and an energy storage device D5, the energy storage unit E6 includes a substrate B6 and an energy storage device D6, and the energy storage unit E6 includes a substrate B6 and an energy storage device D6, wherein the structure and function of the substrates B5, B6 and B7 are the same as those of the substrate B in the first embodiment, and the structure and function of the energy storage devices D5, D6 and D7 are the same as those of the energy storage devices D1, D2, D3 and D4 in the first embodiment.

It should be noted that the wireless management system 2 in the second embodiment has some components that are the same or similar to the wireless management system 1 in the first embodiment. For the sake of convenience, only the differences between the wireless management system 2 and the wireless management system 1 are described below.

Please further refer to FIG. 10, which is a cross-sectional view of the wireless management system 2 in the second embodiment of the present disclosure. As shown in FIG. 10, the light guide element L is disposed above the energy storage units E5, E6 and E7, and the light guide element L has patterns P5 and P6 on a surface opposite to the transceivers T5 and T6, wherein the patterns P5 and P6 may have the same shape as the patterns P11 and P13 in the first embodiment, and the light guide element L may be made of the same material as the light guide elements L1, L2, L3 and L4 in the first embodiment.

Similar to the first embodiment, the optical signals transmitted by the transceivers T5 and T6 can be respectively reflected by the patterns P5 and P6 and transmitted toward the two ends of the light guide element L (e.g., transmitted along the path S4); conversely, the patterns P5 and P6 can also reflect the optical signals transmitted from the two ends of the light guide element L and transmit to the transceivers T5 and T6 respectively (e.g., transmitted along the path S4). In this way, the optical signals transmitted by the transceivers TC2, T5 and/or T6 can pass through the light guide element L and be received by other transceivers in the wireless management system 2.

In some embodiments, the light guide element L can be disposed above the energy storage units E5, E6 and E7 as shown in FIGS. 9 and 10. In this way, when assembling the wireless management system 2, the light guide element L can be installed after the energy storage units E5, E6 and E7 are installed. In other embodiments, the light guide element L can also be installed between the substrate and the energy storage device of the energy storage units E5, E6 and E7, and correspondingly, the transceiver of the substrate B5, B6 and B7 is also changed to be disposed on a surface facing the light guide element L.

Furthermore, as shown in FIG. 11 , the light-guiding element L of the wireless management system 2 may be provided with arc-shaped patterns P7 and P8 on the surface corresponding to the sides of the substrates B5 and B6, wherein the shapes and functions of the patterns P7 and P8 are the same as those of the pattern P12 shown in FIG. 4 , and therefore will not be described in detail.

According to the second embodiment, the controller C2 and the energy storage units E5, E6 and E7 of the wireless management system 2 can transmit optical signals through the light guide element L. In this way, the controller C2 can transmit control signals to the energy storage units E5, E6 and E7 to instruct the substrates B5, B6 and B7 to measure the operating status of the energy storage devices D5, D6 and D7, and the substrates B5, B6 and B7 can transmit the status information obtained after the measurement to the controller C2, thereby achieving the technical purpose of managing the energy storage devices D5, D6 and D7.
