摘要

摘要为了保证锂离子电池的安全运行,需要对电池状态进行实时监控。锂离子电池的表面应变信号具有评估电池状态的潜力,但受温度影响较大。通常可以通过测量电池表面温度和热膨胀系数来量化和消除温度对应变的影响,但这增加了应变测量的成本和复杂性。本文提出了一种无需测量电池温度和材料参数的方法。通过同时测量电池表面的周向应变和轴向应变并计算其差值,可以最小化温度对应变的影响。最后,通过实验验证了该方法的有效性。结果表明,对商用锂离子电池进行温度补偿后,温度对应变的影响可以从16.4 ppm/°C降低到1.7 ppm/°C。该应变不再表现出对电流的敏感性,使其更适合评估锂离子电池的状态。

A Novel Temperature Compensation Method for Surface Strain of Cylindrical Lithium-ion Batteries
Abstract In order to ensure the safe operation of lithium-ion batteries, real-time monitoring of battery status is necessary. The surface strain signal of lithium-ion batteries has the potential to evaluate the battery’s state, but it is significantly affected by temperature. Generally, measuring the battery surface temperature and the thermal expansion coefficient can be performed to quantify and eliminate the influence of temperature on strain, but this increases the cost and complexity of strain measurement. This article proposes a method that eliminates the need to measure the battery temperature and material parameters. By simultaneously measuring the circumferential and axial strains on the battery surface and calculating their difference, the influence of temperature on strain can be minimized. Furthermore, the effectiveness of the proposed method is experimentally tested. Results demonstrate that after applying temperature compensation to commercial lithium-ion batteries, the influence of temperature on strain can be reduced from 16.4 ppm/°C to 1.7 ppm/°C. The strain no longer exhibits sensitivity to current, making it more suitable for evaluating the state of lithium-ion batteries.
