摘　　要：针对磷酸铁锂电池提出了一种融合多种特性的混合电路模型,综合考虑了容量衰减、温度、循环次数、存储时长、电流倍率、自身产热等影响因素,实现了对容量和电压两方面的建模,通过加速衰减实验和脉冲动态实验分别进行容量模型和电压模型参数辨识。最后在Matlab/Simulink中建模仿真,并与实测数据对比,结果表明该模型具有较高的准确性和实用性。A hybrid circuit model for the Li Fe PO4 battery integration of multiple models was proposed. Capacity attenuation, temperature, the number of cycles, the storage duration, the current ration, its own heat production and other factors were considered. Modeling of both capacity and voltage, and the model parameters were identified through accelerated attenuation experiments and pulse dynamics experiments. Then the model was constructed and simulated through Matlab/Simulink and compared with measured data. The results show that the model has relatively high accuracy and practicality.
