摘要：
Energy storage technology is critical for the efficient utilization of renewable energy and the development of the smart grid. Liquid metal battery (LMB) is a newly emerging storage technology with low cost and high efficiency. This paper established equivalent circuit model for the liquid metal battery to simulate its output characteristic accurately. Based on the equivalent circuit model, the estimation of state of charge (SOC) of LMBs was precisely achieved by using Extended Kalman Filter method. This work can be used to predict battery performance under various working conditions and also lay the foundation for the design of reliable, effective battery management for LMBs. © 2017 Chin.
