利用不受外围电路影响的单频阻抗进行锂离子电池在线温度估计

Online temperature monitoring is important for ensuring safe operation of lithium-ion batteries (LIBs). As the battery impedance is related to the internal physical and chemical processes, some efforts have been made to realize sensorless temperature estimation based on the impedance characteristics of LIBs. Unfortunately, the existing impedance-based temperature estimation models are usually deri...
