摘　　要：锂离子电池安全性的定量评估对于保障其稳定、高效运行至关重要。受制于锂离子电池的材料特性、电化学反应机制以及环境影响等复杂因素,目前的评价方法大多提供定性描述,缺乏定量评估。为了解决此问题,本文提出了一种基于势场理论的锂离子电池运行安全状态模型。该模型通过监测锂离子电池的电压、电流等信号,计算电池的运行安全数值,进而评估其安全状态。在此基础上,结合人为设定的安全阈值,该方法在未来的电池安全预警领域具有广阔的应用前景,并通过模拟驾驶条件的实验验证了该模型的可行性和适用性。The quantitative assessment of the safety of lithium-ion batteries is crucial for ensuring stable and efficient operation.Subject to the complex factors of lithium battery,most of the current evaluation methods provide qualitative description and lack of quantitative evaluation.To solve this problem,this paper proposes a lithium battery operation safety state model based on potential field theory.The model monitors signals such as battery voltage and current,calculates the battery's safety value,and then evaluates its safety status.Based on this,and with safety thresholds set by human experience,this method has broad application prospects in future battery safety warning systems.In addition,experiments simulating driving conditions verify the feasibility and applicability of the model.
