[0053] Figure 2 This is a structural schematic diagram of a detector layout determination device in an electrochemical energy storage system provided in an embodiment of the present application. DETAILED DESCRIPTION

[0054] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0055] The rapid development of electrochemical energy storage (EES) systems, particularly breakthroughs in technologies such as lithium-ion batteries, has become the cornerstone of modern applications such as electric vehicles, renewable energy storage, and portable electronic devices. These systems are crucial in addressing the intermittent nature of renewable energy and improving energy efficiency in various fields. However, the widespread use and operational reliability of these systems require advanced monitoring solutions to ensure safety, efficiency, and long-term reliability.

[0056] Electrochemical energy storage systems are inherently complex and susceptible to various fault conditions, which can lead to reduced efficiency, shortened lifetime, or even hazardous situations such as fire or explosion. Effective monitoring through strategically placed detectors is crucial for timely detection and response to faults. However, deploying such detectors presents numerous challenges, including optimizing their placement to cover all potential fault points while minimizing associated costs and remaining within operational constraints.

[0057] The evolution of electrochemical energy storage systems, particularly in areas requiring high reliability, such as renewable energy integration and e-mobility, requires innovative approaches to system monitoring and fault detection. EES systems, such as lithium-ion technology, have played a significant role in energy storage solutions. However, they also present unique challenges, such as thermal runaway, electrode degradation, and electrolyte instability, which can lead to efficiency loss or catastrophic failure. These challenges highlight the importance of effective system monitoring that can predict and mitigate faults before they escalate.

[0058] Traditional monitoring techniques in EES systems focus primarily on voltage, current, and temperature measurements. While these methods provide essential data, they often fail to detect more subtle signs of degradation before they lead to failure. More advanced techniques, such as impedance spectroscopy and thermal imaging, have been introduced to provide more detailed diagnostic information. However, these techniques can be invasive or expensive, limiting their widespread adoption. The placement of sensors or detectors in EES systems often employs heuristics or is based on static configurations, failing to account for the dynamic nature of battery operation. Optimization models for sensor placement, typically using methods such as genetic algorithms, linear programming, or particle swarm optimization, improve performance by balancing coverage and cost. These models prioritize high-risk areas but often ignore operational variables and the probabilistic nature of failures.

[0059] To address this issue, the present invention provides a method for determining the layout of detectors in an electrochemical energy storage system. Figure 1 This is a flow chart of a method for determining detector layout in an electrochemical energy storage system provided in an embodiment of the present application. Figure 1 As shown, the method includes the following steps:

[0060] Step 101, obtaining the installation point of the detector and the position of the battery unit;

[0061] Step 102, determining the coverage variables of each battery cell at each installation point when the detector is installed based on the relationship between the installation point and the position of the battery cell;

[0062] Step 103, determining the total installation cost and the total detection effect based on the cost information, fault information and detection efficiency information of the detector;

[0063] Step 104: Optimize the installation decision variables according to preset constraints with the goal of reducing the sum of the total installation cost and the total detection effect, and obtain target values ​​of the installation decision variables;

[0064] Step 105: Install the detector at the corresponding installation point according to the target value of the installation decision variable.

[0065] In this example, probabilistic risk assessment is combined with an optimization framework to better address the uncertainty of battery failures. These methods dynamically optimize the placement and configuration of sensors by considering various failure scenarios and operating conditions. The use of scenario analysis allows for more adaptive monitoring strategies that are more resilient to potential operational disturbances. The integration of machine learning and artificial intelligence with EES monitoring systems represents a promising area for predictive maintenance. These technologies can learn from historical data to predict future failures, enabling proactive management of EES systems. In addition, the development of more sophisticated models, the integration of real-time data, and continuous learning can significantly improve the accuracy and effectiveness of monitoring systems.

[0066] Current detector placement methods primarily focus on static configurations that do not consider different operating conditions or the probabilistic nature of potential failures. There is an urgent need for a dynamic optimization model that considers not only cost and coverage, but also detector reliability and adaptability to different failure scenarios. This study aims to fill this gap by developing an optimization model that integrates cost, detection reliability, and responsiveness, providing a comprehensive detector deployment approach based on various operational scenarios.

[0067] In this embodiment, the electrochemical energy storage system includes multiple battery cells (also called battery cells). These battery cells are distributed according to a certain pattern. Common arrangements include:

[0068] 1. I-shaped layout: Early electric vehicle battery packs often adopted an I-shaped layout, with the battery cells arranged longitudinally in the center of the vehicle chassis, similar to the letter "I." This layout utilizes existing vehicle space. For example, when converting a fuel vehicle to an electric vehicle, the battery can be installed in the original engine compartment or trunk.

[0069] 2. T-shaped layout: This layout is often used when the battery pack needs to fit within specific vehicle space constraints. For example, in extended-range electric vehicles, the battery pack is designed in a T shape to accommodate the engine and fuel tank. This layout utilizes the center tunnel under the vehicle and the space under the rear seats, improving space utilization.

[0070] 3. U-shaped or L-shaped layout: This is designed to further increase battery capacity by expanding the size or shape of the battery pack to maximize the space under the vehicle. This layout increases the volume and weight of the battery pack, thereby improving the vehicle's range.

[0071] 4. Skateboard Layout: The skateboard layout (also known as flat-bed or integrated) is a common design in modern electric vehicles. The battery pack is designed as part of the vehicle chassis, with the battery cells laid flat under the vehicle floor. This layout helps lower the vehicle's center of gravity, improving vehicle handling and stability while maximizing battery pack size, increasing energy density and range.

[0072] 5. Matrix or honeycomb layout: A matrix or honeycomb layout arranges battery cells in a regular array or honeycomb pattern within the battery pack, facilitating management and cooling while also improving structural rigidity and safety. This layout is often coupled with an efficient thermal management system to ensure consistent battery cell temperatures and mitigate the risk of thermal runaway.

[0073] 6. Modular layout: Modular layout combines battery cells into independently replaceable modules, which facilitates production and maintenance. At the same time, the capacity and shape of the battery pack can be flexibly adjusted to suit different vehicle models and needs.

[0074] The electric vehicle's electronic control system uses a battery management system (BMS) to control battery operation, ensuring safe, efficient, and reliable operation. It monitors physical parameters such as battery voltage, current, and temperature to assess the battery's state of health and remaining charge (SOC). It regulates the voltage and state of charge between individual cells in the battery pack to prevent overcharging or over-discharging of individual cells, thereby extending the overall life of the battery pack. It controls battery temperature to ensure that the battery operates within the optimal temperature range, avoiding overheating or overcooling that can affect battery performance and life. It manages the battery's charge and discharge processes, including controlling charge current and voltage, to prevent overcharging or deep discharge, ensuring safe operation. By detecting faults in the battery system in real time, such as short circuits, open circuits, and overheating, it issues timely alarms and takes necessary protective measures, such as disconnecting the circuit.

[0075] Detectors are used to monitor parameters such as voltage, current, and temperature of each battery cell in the battery and provide early warning of faults. Due to the size of the battery and the cost of installing detectors, it is impossible to install a corresponding detector for every battery cell, so each detector needs to monitor multiple battery cells.

[0076] In order to reduce the installation cost of the detector as much as possible and improve the detection efficiency of the detector, this embodiment designs an optimization model, sets multiple constraints, optimizes the parameters in the model under the constraints of the constraints, and determines the optimal setting method. The detector is set at the corresponding installation point according to the target value of the installation decision variable.

[0077] Optionally, the installation point of the detector is i, the battery unit is j, and the coverage variable is y ij , where when y ij When the value of is 1, it indicates that the detection range of the detector at the installation point i can cover the battery cell j; when y ij When the value of is 0, it indicates that the detection range of the detector at installation point i cannot cover battery cell j.

[0078] In this embodiment, a plurality of installation points are preset in the electrochemical energy storage system, and these installation points are screened to obtain the optimal installation point for installing the detector.

[0079] Optionally, the detector cost information includes the installation cost C of the detector at position i. i , the maintenance cost O of the detector at position i i The fault information includes the fault probability F of the detector at position i i , the probability E that the detector at position i successfully detects battery cell j ij , the probability R that the detector at position i successfully responds to the failure of battery cell j in scenario s ijs , the failure probability P of battery cell j j The detection efficiency information includes the detection efficiency D of the detector at position i for battery cell j ij .

[0080] In this embodiment, the electrochemical energy storage system has multiple operating scenarios. The overall environmental conditions of the system in each operating scenario are quite different, which will cause the detector's success rate in detecting battery cell failures to change. Therefore, the probability R of the detector at position i successfully responding to the failure of battery cell j in scenario s is preset. ijs .

[0081] Optionally, the total installation cost is formulated as:

[0082] Where M is the total number of positions i, x i For the installation decision variable at position i, when x i The value is 1, indicating that the detector is installed at position i; when x i The value of is 1, indicating that the detector is not installed at position i;

[0083] The total detection effect is formulated as follows:

[0084]

[0085] Among them, W s is the weight of scenario s, S is the total number of scenarios, z ijsis the response priority of the detector at position i to battery cell j in scenario s, N is the total number of battery cells, λ is the balancing factor, and Z max,ijs is the upper limit of the detection effect of the detector at position i on battery cell j in scenario s.

[0086] In this embodiment, the installation decision variable is used to determine whether to install a detector at each installation point. Considering the cost of installing the detector and the subsequent dimensional cost of the detector throughout its life cycle, the total installation cost is The physical meaning of this part is that the economic costs of installing the detector and maintaining the operation are taken into account, with the goal of minimizing these costs.

[0087] Includes consideration of detection and response effectiveness, including It represents the sum of the response priorities of battery cells in different scenarios. This factor represents a consideration of detection efficiency and failure probability. The physical meaning of this component is to balance cost and efficiency, optimizing the detector deployment strategy to ensure the system remains efficient and safe in various scenarios. λ is a balancing factor that weighs the importance of cost against detection and response efficiency.

[0088] Optionally, the constraints include:

[0089] Coverage constraints: This constraint ensures that each battery cell is covered by at least one detector. The physical meaning of this constraint is to ensure that the system fully monitors all battery cells.

[0090] Budget constraints: Where B is the total budget; this constraint limits the total cost to within the budget. The physical meaning of this constraint is to ensure the economy and feasibility of the system.

[0091] Operational constraints, including the detector's failure probability and the required detection and response efficiency:

[0092] Constraints on detector installation and coverage: Where I is the set of installation points and J is the set of battery units. This constraint ensures the consistency of the detector layout and coverage relationship. The physical significance of this constraint is to avoid invalid detector layout.

[0093] Detector failure probability constraints: This constraint ensures the reliability and stability of the detector. The physical meaning of this constraint is to prevent the system from losing monitoring efficiency due to detector failure, where Pmin is the lower limit of the detector failure probability.

[0094] Monitoring efficiency constraints: This constraint ensures timely detection of faults. The physical meaning of this constraint is to ensure efficient fault monitoring by the system, where Emin is the lower limit of the monitoring efficiency.

[0095] Response success rate constraints:

[0096] Among them, R min is the lower bound on the probability of successfully responding to a battery cell failure;

[0097] Among them, d ij is the distance between the detector at position i and battery cell j, and β is an adjustment parameter used to adjust the sensitivity of coverage to distance, introducing nonlinear coverage effect attenuation. This constraint ensures timely response and handling of faults. The physical significance of this constraint is to ensure the system's efficient response and safe handling of faults.

[0098] False alarm rate constraint: F i ≤F max , where F i is the false alarm rate of the detector at position i, F max This constraint is used to ensure the reliability of the detector and minimize the operational disruption caused by false alarms.

[0099] Optionally, optimizing the installation decision variable with the goal of reducing the sum of the total installation cost and the total detection effect, and obtaining the target value of the installation decision variable, includes:

[0100] Adjusting the values ​​of the installation decision variables corresponding to each installation point according to the optimization algorithm to reduce the sum of the total installation cost and the total detection effect;

[0101] Obtain a target value of the installation decision variable corresponding to the solution that minimizes the sum of the total installation cost and the total detection effect.

[0102] In one possible embodiment, the minimum value of the objective function (total installation cost + total detection effect) is calculated using a minimum algorithm, for example:

[0103] 1. Gradient Descent: Gradient descent is an iterative optimization algorithm suitable for continuously differentiable objective functions. It updates parameters along the negative gradient, gradually decreasing the objective function. Gradient descent comes in many varieties, including batch gradient descent, stochastic gradient descent, and mini-batch gradient descent.

[0104] 2. Newton's method: The Newton method is a second-order optimization algorithm that uses the second-order Taylor expansion of the objective function to find the minimum. The Newton method has a fast convergence rate, but it requires calculating the second-order derivative matrix (Hessian matrix) of the objective function, which can consume a large amount of memory and computing resources for large problems.

[0105] 3. Quasi-Newton method: The quasi-Newton method is an improvement on the Newton method. Instead of directly calculating the Hessian matrix, it accelerates the optimization process by approximating the Hessian matrix. Typical quasi-Newton methods include BFGS (Broyden-Fletcher-Goldfarb-Shanno) and L-BFGS (Limited-memory BFGS).

[0106] 4. Conjugate Gradient Method: The conjugate gradient method is a first-order optimization algorithm suitable for quadratic objective functions. It can find the minimum value within a finite number of steps and does not require storing the entire gradient history.

[0107] 5. Chalk Method: The Chalk Method (Conjugate Direction Method) is a first-order optimization algorithm suitable for non-quadratic objective functions. The Chalk Method accelerates the optimization process by constructing a set of conjugate directions.

[0108] 6. Coordinate Descent: Coordinate descent is a first-order optimization algorithm that updates only one parameter at a time. It is suitable for situations where the objective function is independent of all parameters. Coordinate descent can be parallelized and is suitable for large-scale problems.

[0109] 7. Random Search: Random search is a simple optimization method that randomly generates parameters and evaluates them on the objective function to find the minimum. Random search is suitable for situations where there is no clear gradient information or the gradient is difficult to calculate.

[0110] 8. Genetic Algorithm: A genetic algorithm is a heuristic optimization method that mimics the biological evolution process and gradually improves parameters through crossover, mutation, and selection operations. Genetic algorithms are suitable for multimodal and non-convex objective functions.

[0111] 9. Particle Swarm Optimization: Particle swarm optimization is a swarm intelligence optimization algorithm that simulates the hunting behavior of flocks of birds to find the minimum value. Particle swarm optimization is applicable to global optimization problems.

[0112] 10. Simulated Annealing: Simulated annealing is a heuristic optimization method that simulates the cooling process of a solid and allows the solution to escape from the local optimum. Simulated annealing is suitable for complex objective functions.

[0113] Optionally, the step of placing the detector at a corresponding installation point according to the target value of the installation decision variable includes:

[0114] The detector is installed at an installation point where the value of the installation decision variable is 1.

[0115] In one possible implementation, an electrochemical energy storage system includes 10 battery cells, each with a different risk profile and operating requirements. The system operates under three different scenarios, reflecting varying operating stresses and failure probabilities: Scenario 1: Normal operation under standard load conditions. Scenario 2: High load conditions, which increase the likelihood of battery failure. Scenario 3: Emergency situations, where rapid system response is crucial.

[0116] The model was implemented to determine the optimal detector placement and configuration across the battery cells. The implementation considered predefined costs, probabilities, and scenario weights as input parameters to solve the optimization problem. The optimization process involved defining the problem constraints and objective function. System parameters and scenario data were input. The solver was run to find the optimal solution that minimized cost and maximized system reliability and responsiveness. The solution was analyzed to evaluate the detector placement and its assigned response priority under each scenario.

[0117] This study successfully developed a comprehensive model for optimizing the deployment of detectors in electrochemical energy storage systems, taking into account cost, efficiency and safety. The model not only helps to deploy detectors cost-effectively, but also ensures the system's responsiveness under various fault conditions. It takes into account potential detector failures and monitoring efficiency, ensuring that the system can maintain the necessary operating performance even when some detectors fail. In addition, the introduction of scenario weights enables the model to optimize the detector response strategy according to different operating conditions, enhancing the adaptability and robustness of the system. Optimized detector deployment can significantly improve the safety and reliability of electrochemical energy storage systems while adhering to budget constraints. The model serves as a decision support tool for designing and operating systems, suitable for the needs of different scales and energy storage applications.
