Operating Data of Echelon-Use Energy Storage Power Station

The power station consists of 4 parallel-connected battery clusters, with each cluster comprising 252 serially connected prismatic cells. The operating mode of this energy storage power station is to profit from the price difference between peak and off-peak electricity tariffs: charging from the power grid during low-tariff periods and discharging to the user side during high-tariff periods. The battery chemistry is lithium iron phosphate (LFP), and the factory capacity of the batteries before retirement is 120Ah.The recording period spans from November 2021 to May 2022.
