[0056] FIG. 1 is a block diagram of a wireless battery management system according to one embodiment of the present invention.

[0057] Referring to FIG. 1, the wireless battery management system (100) of the present embodiment may include a memory (110) and a master controller (120), and each component (110, 120) may form a battery pack together with a battery managed by the BMS in the present embodiment.

[0058] At least one command executed by the master controller (120) described below may be stored in the memory (110). The memory (110) may be implemented as a volatile storage medium and / or a non-volatile storage medium, for example, as a read-only memory (ROM) and / or random access memory (RAM).

[0059] In addition, the memory (110) may store data related to the network environment of the wireless battery, such as RSSI (Received Signal Strength Indicator), PDR (Pedestrian Dead Reckoning), network delay, and EMI (Electromagnetic Interference) level.

[0060] Additionally, the memory (110) may store external factor data including at least one of vehicle vibration, temperature change, and ambient electromagnetic environment. This data may be used to optimize the dynamic network topology of the wireless battery by the master controller (120) described later.

[0061] The master controller (120) is the entity managing the wireless battery and can be implemented as a Central Processing Unit (CPU) or a System on Chip (SoC). It can control multiple hardware or software components connected to the master controller (120) by running an operating system or application, and can perform various data processing and calculations. The master controller (120) can be configured to execute at least one command stored in memory (110) and store the execution result data in memory (110).

[0062] Meanwhile, the master controller (120) may be implemented as a Battery Management System (BMS) provided in the battery pack or a Micro Controller Unit (MCU) inside the BMS, and may be configured to detect external factor data including at least one of vehicle vibration, temperature change, and surrounding electromagnetic environment as previously mentioned.

[0063] Below, the operation of the master controller (120) managing the wireless battery is described in detail.

[0064] The master controller (120) can collect data and store it in memory (110), and optimize the dynamic network topology of the wireless battery through AI-based data analysis. At this time, the master controller (120) can perform data analysis using a network topology optimization engine that uses a Deep Reinforcement Learning algorithm as a technical means.

[0065] At this time, the master controller (120) can manage the wireless battery by analyzing at least one of the data of RSSI, PDR, network delay, and EMI level based on AI and optimizing the dynamic network topology of the wireless battery.

[0066] Additionally, the master controller (120) can optimize the dynamic network topology of the wireless battery by analyzing external factor data including at least one of vehicle vibration, temperature change, and surrounding electromagnetic environment based on AI, and dynamically reconstructing the network structure by integrating the analysis results (including the previous analysis results).

[0067] To this end, the master controller (120) can collect data from each node within the topology of the wireless battery at regular intervals and perform data preprocessing on the collected data. That is, the master controller (120) can complete data preprocessing on the collected data by normalizing the collected data and then applying a moving average filter to the normalized data to remove noise.

[0068] For example, the master controller (120) can collect data such as RSSI, PDR, and EMI at 1-second intervals from each node and normalize the collected data as follows: '(RSSI + 100) / 100' for RSSI, 'PDR / 100' for PDR, and 'EMI / 10' for EMI. Then, the master controller (120) can complete the data preprocessing process by applying a moving average filter (window size: 5 seconds) to the normalized data to remove noise.

[0069] The master controller (120) can evaluate the network status of the wireless battery based on the preprocessed data and predict the optimal network configuration based on the evaluation result of the network status to determine the topology change of the wireless battery.

[0070] To this end, the master controller (120) can determine a Q-table based on the network state of the wireless battery and determine an active path and a standby path based on the Q-table using an epsilon-greed algorithm. For example, the master controller (120) can calculate Q(S_t, A) with the current network state S_5 as input and select an action according to an epsilon-greed policy (epsilon = 0.1). That is, the master controller (120) can select an action with the maximum Q value with a 90% probability and a random action with a 10% probability.

[0071] The master controller (120) can execute a selected action A_t (e.g., changing the path, adjusting the transmission power, etc.) and calculate an immediate reward R_t upon observing a new state S_t+1 (R_t = w1*△PDR + w2*△RSSI + w3*△EMI + w4*△Delay, w1=0.4, w2=0.3, w3=0.2, w4=0.1). The master controller (120) can store the experience (S_t, A_t, R_t, S_t+1) in a replay memory, randomly extract a batch (size: 32) from the replay memory, and perform training (learning rate: 0.001, discount rate: 0.99) and updating of a Deep Q-Network (DQN) model with the extracted batch.

[0072] According to one embodiment, the master controller (120) can reconfigure the topology around nodes that are less affected when the EMI level increases during driving. Additionally, the master controller (120) can distribute the load by adjusting the data transmission path of the battery module when the temperature of the battery module rises.

[0073] Meanwhile, the master controller (120) can reduce communication errors caused by EMI by learning and predicting EMI patterns based on AI to select the optimal frequency and modulation method, and by monitoring EMI intensity and adjusting communication parameters. To this end, the master controller (120) can determine a Q-table based on the network status of the wireless battery and determine a frequency change channel based on the Q-table using an epsilon-greedy algorithm.

[0074] At this time, the master controller (120) can monitor the EMI level of the frequency band in real time using AI-based spectrum sensing and dynamic frequency allocation algorithms as technical means, predict the EMI pattern through EMI pattern learning to select the optimal frequency band, and dynamically switch the modulation method according to the communication environment.

[0075] According to an embodiment, the master controller (120) can generate a frequency hopping sequence that avoids periodic EMI patterns that occur during high-speed driving after learning them. Additionally, the master controller (120) can automatically switch to a more robust modulation method (e.g., QPSK) by taking into account signal attenuation when entering a tunnel.

[0076] The master controller (120) can use an edge computing-based distributed AI processing system and a machine learning-based routing algorithm as technical means to deploy a lightweight AI model to each battery module and perform data preprocessing and initial analysis locally, and can optimize the entire network in cooperation with a central AI system.

[0077] According to the embodiment, the master controller (120) can immediately notify the central system when abnormal signs are detected, based on the results of the self-status analysis of each module. In addition, the master controller (120) can predict network congestion and dynamically set the priority transmission path for important data.

[0078] Meanwhile, the master controller (120) can reduce the power consumption of the BMS by dynamically adjusting the optimal power level for the RF antenna output through the analysis of at least one of the data of the battery status, communication requirements, and surrounding environment of each node in the AI-based topology.

[0079] At this time, the master controller (120) can use a deep learning-based power consumption prediction model and a dynamic power allocation algorithm as technical means to analyze the battery status, communication requirements, and surrounding environment of each node in real time, predict future power consumption patterns and determine the optimal power level, and dynamically adjust the transmission power of each node.

[0080] According to one embodiment, the master controller (120) can reduce the transmission power of a module with a low battery level and enable surrounding modules to strengthen the relay role, minimize unnecessary communication when the vehicle is stopped, and reduce standby power consumption.

[0081] Meanwhile, the master controller (120) can implement each function (topology optimization, EMI response, power management, etc.) as an independent AI module by utilizing a modularized AI system and online learning algorithm based on a microservices architecture as technical means, and can perform continuous model updates and performance improvements based on new data. In addition, the master controller (120) can learn the characteristics of each vehicle model and automatically adjust the optimization strategy.

[0082] According to one embodiment, when a new battery module is added, the master controller (120) can automatically learn the characteristics of the new battery module and integrate the newly added battery module into the existing system based on the learned characteristics. In addition, the master controller (120) can learn changes in battery performance according to changes in driving patterns and automatically adjust the BMS strategy.

[0083] The master controller (120) can use a time series prediction model based on an LSTM (Long Short-Term Memory) network as a technical means to analyze voltage, current, and temperature data at the individual cell and module level in a time series, and predict battery performance considering various operating conditions and environmental factors to detect signs of battery abnormalities early and predict battery life.

[0084] According to the embodiment, the master controller (120) can generate a preemptive warning when detecting a sudden temperature change or an excessive charge / discharge pattern. In addition, the master controller (120) can analyze the performance deviation of individual cells within the battery pack to establish an optimal balancing strategy.

[0085] The master controller (120) can learn normal communication patterns and detect abnormal behavior in real time by using a Generative Adversarial Network (GAN)-based anomaly detection model and a quantum-resistant encryption algorithm as technical means, and can dynamically adjust the encryption strength and method according to the detected threat. In addition, the master controller (120) can learn continuous security threats and update response strategies.

[0086] According to one embodiment, the master controller (120) may isolate the node and require additional authentication when an abnormal data request pattern is detected. Additionally, the master controller (120) may immediately deploy a defense strategy to the entire network when a new type of cyber attack is detected.

[0087] In addition, based on the combination of a lightweight AI model at the edge device and a cloud-based high-performance AI engine, real-time data processing and initial decision-making can be performed at the edge device level. Furthermore, the master controller (120) can process complex analysis and long-term learning in the cloud AI engine and perform overall system optimization through periodic model synchronization.

[0088] According to one embodiment, the master controller (120) may have edge AI handle real-time battery management during driving, and cloud AI handle detailed analysis and optimization after driving. Additionally, the master controller (120) may distribute a new optimization strategy learned in the cloud to edge devices via an OTA (Over-The-Air) update.

[0089]

[0090] Figures 2 and 3 are example diagrams illustrated to explain the xEX wireless BMS network structure and dynamic topology changes.

[0091] First, as shown in FIG. 2, the network structure of the xEV wireless BMS is based on a hierarchical mesh topology and consists of a master controller (MC) (120), relay nodes (RN) (210, 211, 212) and battery module nodes (BMN) (220, 221, 222, 223, 224) as its main components.

[0092] Here, the master controller (120) serves as the central control unit of the entire network, is equipped with an AI-based dynamic topology optimization engine, and is directly connected to the vehicle's main ECU to manage the entire battery system. The relay nodes (210, 211, 212) can act as communication relays between the master controller (120) and the battery module nodes (220, 221, 222, 223, 224). The relay nodes (210, 211, 212) can perform local network optimization and data aggregation functions, and can also perform dynamic routing and load balancing functions. The battery module nodes (220, 221, 222, 223, 224) are communication nodes directly connected to individual battery modules, and can collect and transmit real-time data such as voltage, current, and temperature, and perform local data processing by being equipped with a lightweight edge AI model.

[0093] Next, referring to FIG. 3, an example of a dynamic topology change is described as follows. When a high temperature is detected at battery module node 2 (BMN2) (221), the master controller (120) can change the direct communication path from relay node 1 (RN1) (210) to battery module node 2 (BMN2) (221) as in FIG. 2, as the connection weakens due to a deterioration in link quality between relay node 1 (RN1) (220) and battery module node 2 (BMN2) (221), to a path from relay node 1 (RN1) (210) to battery module node 3 (BMN3) via battery module node 1 (BMN1) (220) and battery module node 2 (BMN2) (221) as in FIG. 3.

[0094] When high temperature is detected at the battery module node (BMN5) (224), the master controller (120) can change the direct communication path from relay node 3 (RN3) (212) to the battery module node 5 (BMN5) (224) as shown in FIG. 2, as the connection weakens due to a deterioration in link quality between relay node 3 (RN3) (222) and the battery module node 5 (BMN5) (224), to a path from the battery module node 5 (BMN5) (224) to the battery module node 6 (BMN6) (225) as shown in FIG. 3. Additionally, the master controller (120) can set a priority path through the battery module node 5 (BMN5) (224) due to the occurrence of critical data at the battery module node 6 (BMN6) (225).

[0095] As described above, in this embodiment, the network structure can be adjusted in real time through AI-based dynamic topology optimization, EMI response capabilities can be improved by introducing AI-based frequency hopping technology and adaptive modulation schemes, and real-time data processing and latency can be minimized by implementing distributed AI processing and multi-hop routing optimization. In addition, in this embodiment, energy efficiency can be improved by introducing an AI-based adaptive power control system, and scalability and flexibility can be improved by significantly enhancing applicability to various xEV models through the provision of a system equipped with a modular AI architecture and self-learning capabilities.

[0096] According to the present invention, communication efficiency is significantly improved, and stable performance can be maintained even under various driving conditions. This is because the AI ​​continuously maintains an optimal network structure by analyzing RSSI, PDR, EMI levels, etc., in real time. Furthermore, according to the present invention, communication stability can be guaranteed by dynamically reconfiguring the network structure by considering various external factors such as vehicle vibration, temperature changes, and the surrounding electromagnetic environment.

[0097] Furthermore, according to the present invention, the communication error rate caused by EMI can be significantly reduced. This is because the AI ​​learns and predicts EMI patterns to select the optimal frequency and modulation method. In addition, according to the present invention, stable communication can be maintained even in high-voltage environments by monitoring EMI intensity in real time and immediately adjusting communication parameters accordingly.

[0098] Furthermore, according to the present invention, data processing delays can be significantly reduced and real-time control accuracy can be improved. This is because partial data processing is performed at each node, and the AI ​​continuously calculates the optimal routing path. Additionally, according to the present invention, critical information is rapidly transmitted through a priority-based data processing algorithm, and overall system responsiveness can be improved through the function of predicting and avoiding network congestion.

[0099] Furthermore, according to the present invention, the power consumption of the BMS can be significantly reduced. This is because the AI ​​dynamically adjusts the optimal power level for the RF antenna output by considering the battery status, communication requirements, and surrounding environment of each node. Additionally, according to the present invention, unnecessary power consumption can be prevented in advance through the prediction of usage patterns. Moreover, according to the present invention, the applicability to various xEV models can be greatly enhanced. This is because the system can automatically learn and optimize new battery configurations and vehicle characteristics. Furthermore, according to the present invention, network configurations can be flexibly changed by utilizing Software Defined Networking (SDN) technology, and continuous performance improvement can be enabled through cloud-based updates.
