Each 1 MW/2 MWh energy storage container includes two sets of 500 kW PCS, 2 MWh battery and corresponding battery management system. In order to simulate various situations, this paper assumes that PCS units 1–100 are divided into 5 groups, every 20 is a group.
Thus, the safety early warning of LiFePO 4 batteries in energy storage systems is difficult. To address the problem of safety early warning in LiFePO 4 batteries in energy storage systems, we propose a multitime scale comprehensive early warning strategy based on the consistency deviation of electric and thermal characteristics.
