Electrical Equivalence Model Research Based on Electrochemical Mechanism Characteristics of Lithium-ion Battery
To characterize the internal and external dynamic conditions of lithium-ion batteries under low-rate charging and discharging conditions more accurately,this paper derives a mechanism electrical equivalent model based on the electrochemical principles of lithium-ion batteries.It clarifies the calculation methods for related electrical component parameters of the mechanism electrical equivalent model,revealing the correlation between them and lithium-ion battery electrochemical parameters.The proposed mechanism electrical equivalent model combines the accuracy of lithium-ion electrochemical models and the convenience advantages of conventional empirical circuit models in energy storage control parameters tuning and large-scale energy storage station equivalent modeling.It is more suitable for modeling,simulation,parameter setting,and safety monitoring of energy storage power stations in new power system scenarios.
