摘　　要：准确预测超级电容器使用寿命是其在电动汽车领域可靠应用的关键。通过超级电容器在不同充放电电流和温度条件下所表现的性能衰减规律,基于经典阿列纽斯模型,建立了包括温度、电流强度和循环次数因子的超级电容器容量衰减预测模型。验证结果表明,拟合结果与实际衰减数据的一致性较好,绝大部分相对误差在3%以内。该模型可适用于不同结构设计的超级电容器,并可用于指导超级电容器使用过程中的充放电电流和温度设置。Accurate prediction of the service life is the key for the reliable application of supercapacitors in the field of electric vehicles. Based on the classical Arrhenius model and the performance attenuation law of supercapacitors under different charging/discharging currents and temperatures, the prediction model for capacity loss of supercapacitors including temperature, current intensity and cycle factor was established. The verification results show that the fitting results are in good agreement with the actual attenuation data, and most of the relative errors are within 3%. The model can be applied to supercapacitors with different structures and can be used to guide the charging/discharging current and temperature setting during the use of supercapacitors.
