With the large-scale development of lithium-ion battery energy storage power station

its operation safety and condition evaluation accuracy are facing severe challenges. Traditional monitoring methods have some problems

such as single evaluation index

poor data coordination

delay of fault early warning and so on

which are difficult to meet the actual engineering needs. This paper systematically analyzes the key parameters of intelligent monitoring technology of lithium-ion battery energy storage power station

discusses various intelligent monitoring technologies such as electrochemical impedance method

equivalent circuit model and data-driven method

and puts forward the operation guarantee method of lithium-ion battery energy storage power station

which provides important theoretical basis and engineering practice scheme for optimal management of energy storage power station.
