Online Parameter Identification and State of Charge Estimation of Lithium-Ion Batteries Based on Forgetting Factor Recursive Least Squares and Nonlinear Kalman Filter

Energies, 2017
State of charge (SOC) estimation is the core of any battery management system. Most closed-loop SOC estimation algorithms are based on the equivalent circuit model with fixed parameters. However, the parameters of the equivalent circuit model will change

Experimental demonstration of an atomtronic battery

New Journal of Physics, 2017
Operation of an atomtronic battery is demonstrated where a finite-temperature Bose–Einstein condensate stored in one half of a double-well potential is coupled to an initially empty load well that is impedance matched by a resonant terminator beam.

Voltage sag source identification based on the sign of internal resistance in a “Thevenin's equivalent circuit”

International Transactions on Electrical Energy Systems, 2017
Summary This paper briefly introduces the existing methods for voltage sag source location and theoretically analyzes some reasons why high accuracy cannot be achieved by using these methods. Based on the redefined voltage sag source location “reference direction” and the analysis of voltage sag source's influences in power network, it is pointed out ...
