锂离子电池界面电容充放电深度的计算与分析
Calculation and analysis of depth of charge/discharge of interfacial capacitance for lithium ion battery
摘要
Abstract
Theoretical calculation and experimentl validation was conducted to answer how the resting time affect pulse current method ,aiming at parameter identification of circuit mode for lithium ion battery (LIB) .Firstly ,an analytical solution of a second‐order circuit model for LIB was solved under bi‐pulse excitement ,followed by simulation for transient response voltage .Subsequently ,the depth of charge /discharge was defined and formulated for interfacial capacitance ,and effect of resting time on charge stored in interfacial capacitance was quantitatively studied .Finally ,the test of charge/dis‐charge and AC impedance for 15AH‐NCM LIB were carried out with Solartron 1470E‐1455 worksta‐tion ,and experimental results were in agreement with the above conclusions .关键词
