For example, it may be a fixed connection, a removable connection, or an integral connection. It may be a mechanical connection, an electrical connection, or mutual communication. It may be a direct connection, an indirect connection via an intermediate medium, or an internal connection between two elements or an interaction relationship between two elements.

[0019] In related technologies, when combining and mounting a plurality of battery boxes on a vehicle, it is restricted by the overall layout of the vehicle. Also, due to differences in the external dimensions of the battery boxes, the battery management unit and the battery monitoring unit of the battery management system cannot be mounted in the same area, and the communication harness between the battery management unit and the battery monitoring unit is too long, so there is a problem that signal distortion is likely to occur.

[0020] As shown in Figure 1, an embodiment of the present invention first provides a battery management system communication method applied to a relay unit 1 of the battery management system. The battery management system further includes a battery monitoring unit 2 and a battery management unit 3, and the battery monitoring unit 2, the battery management unit 3 and the relay unit 1 are connected to the same communication network. Here, the communication network may be a CAN (Controller Area Network) network, the battery monitoring unit 2 is used to collect battery status information data such as temperature and voltage of the battery modules in the battery box, and the battery management unit 3 is used to maintain the battery modules in a normal operating state by performing data processing and analysis on the battery status information collected by the battery monitoring unit 2 and then transmitting control commands to the battery monitoring unit 2, the battery modules and other related components. The relay unit 1 is installed in the middle position of the CAN network.

[0021] The battery management system of this embodiment generally includes one battery management unit 3 and multiple battery monitoring units 2, each of which monitors the status information of one battery module, and multiple battery modules correspond to multiple battery monitoring units 2.

[0022] The main entity executing the battery management system communication method in this embodiment is the relay unit 1, and as shown in Figure 2, it includes steps 101, 102, and 103. Specifically, it is as follows.

[0023] In step 101, battery status information is received from the battery monitoring unit 2, where the battery status information includes, but is not limited to, at least one of the following: the temperature of the battery module, the voltage of the battery module, etc.

[0024] In step 102, the battery status information is enhanced, and the enhanced battery status information is obtained.

[0025] In one embodiment, the above steps specifically include the step of performing filtering and / or amplification processing on the battery state information and obtaining the filtered and / or amplified battery state information.

[0026] In this way, by performing enhancement processing on the battery status information transmitted from the battery monitoring unit 2 by the relay unit 1, signal quality is improved, signal distortion is prevented, the effect of extending the communication network is achieved, and the effective communication distance is extended.

[0027] In one embodiment, step 102 further includes adjusting the baud rate of the enhanced battery status information to match the baud rate of the enhanced battery status information to the communication network.

[0028] In this way, the relay unit 1 matches battery status information to communication networks having different communication baud rates and can freely switch between the CAN network and the CANFD network, thereby ensuring normal communication between the battery management unit 3 and the battery monitoring unit 2. Here, the CANFD network is based on the CAN network with some upgrades and improvements.

[0029] In step 103, the enhanced battery status information is transmitted to the battery management unit 3, and the battery management unit 3 controls the battery's operating status according to the enhanced battery status information.

[0030] After enhancement processing by relay unit 1, situations such as signal power attenuation and signal distortion in the battery status information are avoided, and battery management unit 3 can receive accurate battery status information without distortion. If battery management unit 3 receives an incorrect message, it can cause an incorrect judgment and send an incorrect command, thus preventing a safety hazard to the vehicle's battery system.

[0031] In one embodiment, after step 101, The step of obtaining the signal power of the battery state information, It further includes the step of determining whether to perform enhancement processing on the battery state information according to the signal power of the battery state information.

[0032] Specifically, assume that the signal power of the battery state information is P1 and the first threshold is Pth1. Here, the first threshold is a predetermined fixed signal power value for determining whether to perform enhancement processing on the battery state information. Compare the magnitude relationship between the signal power P1 of the battery state information and the first threshold Pth1. [[ID=۸]]When P1 < Pth1, it is determined that there is significant signal attenuation in the current battery state information, there is a risk of signal distortion, and it is necessary to perform enhancement processing on the battery state information. Therefore, proceed to step 102. When P1 ≥ Pth1, it is determined that the current battery state information is normal and there is no need for enhancement processing. Therefore, directly transmit the battery state information to the battery management unit 3.

[0033] In the battery management system communication method of this embodiment, first, receive the battery state information from the battery monitoring unit 2, then perform enhancement processing on the battery state information, obtain the enhanced battery state information, and finally transmit the enhanced battery state information to the battery management unit 3, and control the operation status of the battery according to the enhanced battery state information by the battery management unit 3. In this embodiment, the relay unit 1 performs enhancement processing on the information transmitted between the battery monitoring unit 2 and the battery management unit 3, and reduces the attenuation in the information transportation process, thereby extending the transmission distance in the communication network between the battery monitoring unit 2 and the battery management unit 3, and alleviating the problem that the communication harness between the battery management unit 3 and the battery monitoring unit 2 is too long and signal distortion is likely to occur.

[0034] Embodiments of the present invention provide another battery management system communication method applicable to a relay unit 1 of a battery management system, the battery management system further comprising a battery monitoring unit 2 and a battery management unit 3, the battery monitoring unit 2, the battery management unit 3, and the relay unit 1 being connected to the same communication network. Here, the communication network may be a CAN network, the battery monitoring unit 2 is used to collect battery state information data such as temperature and voltage of the battery module, and the battery management unit 3 is used to maintain the battery module in a normal operating state by performing data processing and analysis on the battery state information collected by the battery monitoring unit 2 and then transmitting control commands to the battery monitoring unit 2, the battery module, and other related components. The relay unit 1 is installed in the middle of the CAN network.

[0035] The battery management system of this embodiment generally includes one battery management unit 3 and multiple battery monitoring units 2, each of which monitors the status information of one battery module, and multiple battery modules correspond to multiple battery monitoring units 2.

[0036] The main entity executing the battery management system communication method in this embodiment is the relay unit 1, and as shown in Figure 3, it includes steps 201, 202, and 203. Specifically, it is as follows.

[0037] Step 201: Receive command information from the battery management unit 3.

[0038] Step 202: Enhancement processing is performed on the command information, and the enhanced command information is obtained.

[0039] In one embodiment, the above steps may specifically include the step of performing filtering and / or amplification processing on the command information and obtaining the filtered and / or amplified command information.

[0040] In this way, by performing enhancement processing on the command information transmitted from the battery management unit 3 by the relay unit 1, signal quality is improved, signal distortion is prevented, the effect of extending the communication network is achieved, and the effective communication distance is extended.

[0041] In one embodiment, step 202 further includes adjusting the baud rate of the enhanced command information to match the baud rate of the enhanced command information to the communication network.

[0042] Thus, the relay unit 1 matches command information to communication networks having different communication baud rates and can freely switch between the CAN network and the CANFD network, thereby ensuring normal communication between the battery management unit 3 and the battery monitoring unit 2. Here, the CANFD network is based on the CAN network with some upgrades and improvements.

[0043] Step 203 includes transmitting the enhanced command information to the battery monitoring unit and causing the battery monitoring unit to execute the enhanced command information.

[0044] After enhancement processing by relay unit 1, situations such as signal power attenuation and signal distortion in the command information are avoided, allowing battery monitoring unit 2 to receive accurate command information without distortion. This prevents battery monitoring unit 2 from receiving incorrect commands and executing incorrect operations, thereby preventing safety hazards to the vehicle's battery system.

[0045] In one embodiment, after step 201, Steps include acquiring the signal power of the command information, The process includes the step of determining whether or not to perform enhancement processing on the command information according to the signal power of the command information.

[0046] Specifically, let the signal power of the command information be P2 and the second threshold be Pth1. Here, the second threshold is also a preset fixed signal power value, which is used to determine whether to perform enhancement processing on the command information. Compare the magnitude relationship between the signal power P2 of the command information and the second threshold Pth2. When P2 < Pth2, it is determined that there is significant signal attenuation in the current command information and there is a signal distortion situation, and it is necessary to perform enhancement processing on the command information. Therefore, proceed to step 202. When P2 ≥ Pth2, it is determined that the current command information is normal and there is no need to perform enhancement processing. Therefore, directly transmit the command information to the battery monitoring unit 2.

[0047] In the battery management system communication method of this embodiment, first, receive the command information from the battery management unit 3, then perform enhancement processing on the command information to obtain the enhanced command information, and finally, transmit the enhanced command information to the battery monitoring unit 2 to make the battery monitoring unit 2 execute the enhanced command information. In this embodiment, the relay unit 1 performs enhancement processing on the information transmitted between the battery monitoring unit 2 and the battery management unit 3, and reduces the attenuation in the information transportation process, thereby extending the transmission distance in the communication network between the battery monitoring unit 2 and the battery management unit 3, and alleviating the problem that the communication harness between the battery management unit 3 and the battery monitoring unit 2 is too long and signal distortion is likely to occur.

[0048] The embodiment of the present application simultaneously provides a battery management system applicable to the battery management system communication method provided in the above embodiment. As shown in FIG. 1, the battery management system includes a battery monitoring unit 2, a battery management unit 3, and a relay unit 1. Here, the battery monitoring unit 2 is used to collect battery state information and is connected to the communication network. The battery management unit 3 is used to control the operation status of the battery according to the battery state information and is connected to the communication network. The relay unit 1 is connected to the communication network, is located between the battery management unit 3 and the battery monitoring unit 2, and is used to enhance the information transmitted between the battery management unit 3 and the battery monitoring unit 2.

[0049] In the battery management system of this embodiment, the relay unit 1 performs enhancement processing on the information transmitted between the battery monitoring unit 2 and the battery management unit 3, reducing attenuation during the information transport process. This extends the transmission distance in the communication network between the battery monitoring unit 2 and the battery management unit 3, mitigating the problem of signal distortion that is likely to occur due to the excessive length of the communication harness between the battery management unit 3 and the battery monitoring unit 2.

[0050] In one embodiment, the relay unit 1 is located in the middle region of the communication network. This simplifies the wiring of the communication network between the battery monitoring unit 2 and the battery management unit 3, improves the relay effect of the relay unit 1, and prevents signal distortion from occurring in communication between the relatively distant battery monitoring unit 2 and the battery management unit 3.

[0051] In one embodiment, as shown in Figures 4 and 5, the relay unit 1 comprises a box 11 and a repeater 12, the repeater 12 being located inside the box 11 and connected to a communication network. Here, the box 11 may specifically be a low-voltage box. The low-voltage box can adequately protect the repeater 12, allowing the repeater 12 to operate normally, ensuring the relay effect of the repeater 12 unit, and enabling enhanced processing of information transmitted stably between the battery monitoring unit 2 and the battery management unit 3.

[0052] In one embodiment, the relay unit 1 further includes a connector 13, which is installed in the housing 11. One end of the connector 13 is connected to the repeater 12, and the other end is connected to the communication network. The connection action of the connector 13 enables the formation of a stable connection between the repeater 12 and the communication network.

[0053] In one embodiment, the connector 13 includes a first connector 131 and a second connector 132, wherein one end of the first connector 131 is connected to the repeater 12 and the other end is connected to the communication network, and one end of the second connector 132 is disconnected from the repeater 12 and the other end is connected to the communication network.

[0054] In this way, the necessity of the relay effect can be determined according to the actual situation. If it is necessary for the relay unit 1 to perform signal enhancement processing between the battery monitoring unit 2 and the battery management unit 3, the relay 12 can be connected to the communication network via the first connector 131. If it is not necessary for the relay unit 1 to perform signal enhancement processing between the battery monitoring unit 2 and the battery management unit 3, the relay 12 will not be connected to the communication network by directly connecting the communication network to the second connector 132.

[0055] In one embodiment, when the IP (ingress protection) protection level of the connector 13 reaches IP68 or higher, it is possible to completely prevent the ingress of external dust, prevent water ingress when submerged, and prevent the effects of prolonged immersion in water exceeding 1 meter in depth.

[0056] In one embodiment, as shown in Figures 6 to 11, the enclosure 11 comprises a housing 111 and a lid plate 112, and the lid plate 112 and the housing 111 are sealed together by a sealing member 15. Here, the sealing member 15 may be a sealing strip, and its material may be rubber. If the IP protection level of the enclosure 11 is IP67 level or higher, it can completely prevent the intrusion of external dust, prevent water ingress when submerged, and prevent the effects of submersion in water to a depth of 1 meter for 30 minutes. This ensures that the repeater 12 operates in a safe and stable environment.

[0057] In one embodiment, the lid plate 112 and the housing 111 are fixedly connected by a fixing member. The fixing member may be a bolt, which ensures the overall strength of the box body 11, allows it to withstand a certain amount of impact, and provides good protection for the repeater 12.

[0058] Specifically, sheet metal folding welding is employed for the housing 111. By fixing with bolts, the cover plate 112 and the housing 111 create a pressing action against the seal strip, eliminating the gap between the cover plate 112 and the housing 111 and fulfilling the IP protection requirements.

[0059] In one embodiment, the box body 11 further comprises a fixing sheet 14, to which the fixing sheet 14 is connected to the bottom of the housing 111, and the fixing sheet 14 is provided with fixing connection holes 141. The fixing sheet 14 is stably connected to the vehicle by fitting bolts into the fixing connection holes 141, thereby preventing the box body 11 from being displaced while the vehicle is in motion.

[0060] In one embodiment, the battery management system further includes a load carrier 4, which is provided in the communication network to stabilize the voltage of the communication network. This makes it possible to suppress fluctuations in the communication network.

[0061] The resistance of the load carrier 4 is between 100 ohms and 200 ohms, and specifically, it may be a resistance of 120 ohms, 150 ohms, etc. This effectively reduces fluctuations in the communication network.

[0062] The specific operation method of the battery management system in this embodiment is as follows:

[0063] First, the relay unit 1 receives battery status information from the battery monitoring unit 2, where the battery status information includes, but is not limited to, at least one of the following: the temperature and voltage of the battery module.

[0064] Next, the relay unit 1 performs enhancement processing on the battery status information and obtains the enhanced battery status information. Specifically, the relay unit 1 performs filtering and / or amplification processing on the battery status information and obtains the filtered and / or amplified battery status information. In this way, by performing enhancement processing on the battery status information transmitted from the battery monitoring unit 2 by the relay unit 1, the signal quality is improved, the signal is not distorted, the effect of extending the communication network is achieved, and the effective communication distance is extended. Furthermore, the relay unit 1 adjusts the baud rate of the enhanced battery status information to match the baud rate of the enhanced battery status information to that of the communication network.

[0065] Finally, the relay unit 1 transmits the enhanced battery status information to the battery management unit 3, and the battery management unit 3 controls the battery's operating status according to the enhanced battery status information.

[0066] On the other hand, the specific operation method of the battery management system may be as follows:

[0067] First, relay unit 1 receives command information from battery management unit 3.

[0068] Next, the relay unit 1 performs enhancement processing on the command information and obtains the enhanced command information. Specifically, it performs filtering and / or amplification processing on the command information and obtains the filtered and / or amplified command information. In this way, by performing enhancement processing on the command information transmitted from the battery management unit 3 by the relay unit 1, the signal quality is improved, the signal is not distorted, the effect of extending the communication network is achieved, and the effective communication distance is extended. Furthermore, the relay unit 1 adjusts the baud rate of the enhanced command information to match the baud rate of the enhanced command information to the communication network.

[0069] Finally, relay unit 1 transmits the enhanced command information to battery monitoring unit 2, causing battery monitoring unit 2 to execute the enhanced command information.

[0070] The battery management system of this embodiment implements the battery management system communication method provided in the above embodiment, and the relay unit 1 performs enhancement processing on the information transmitted between the battery monitoring unit 2 and the battery management unit 3, thereby reducing attenuation during the information transport process. This extends the transmission distance in the communication network between the battery monitoring unit 2 and the battery management unit 3, and mitigates the problem of signal distortion that is likely to occur due to the communication harness between the battery management unit 3 and the battery monitoring unit 2 being too long.
