The accurate state of charge (SoC) online estimation is a significant indicator that relates to driving ranges of electric vehicles (EV). The relationship between open circuit voltage (OCV) and SoC plays an important role in SoC estimation for lithium-ion batteries. To compare with the traditional incremental OCV (IO) test and the low current OCV (LO) test, a novel OCV test which combines IO test with LO test (CIL) is proposed in this paper. Based on the reliable parameters online identification of the dual polarization (DP) battery model, two SoC estimation algorithms are compared on the accuracy, robustness and convergence speed for the entire SoC region. Meanwhile, the comparative study of the three OCV-SoC relationships fits by the corresponding OCV tests is discussed in terms of the SoC online estimation under various temperatures. The results show that the adaptive extended Kalman filter (AEKF) algorithm can better improve the accuracy and robustness of SoC estimation than that of the extended Kalman filter (EKF) algorithm. Most importantly, the OCV-SoC relationship obtains from the CIL OCV test method is applied to the AEKF algorithm, which has higher accuracy and better statistical indices of SoC estimation, especially suitable for the low temperature.

For many years, Unmanned Aerial Vehicle Swarm (UAVs) have been implemented as standalone systems for various applications. Advances in technology necessitate the need for the complexity of the systems to rise to a level higher than ever. The capability needs today require the use of multiple systems to act together to accomplish a common goal that is unachievable with a single system. The use of multiple UAVs in an autonomous, or semi-autonomous, nature to accomplish this higher-level goal is known as a UAV Swarm system of systems. In designing a system with the complexity of a UAV Swarm there are many aspects that must be taken into careful consideration. This article will identify the SoS principles and considerations for developing and deploying a UAV Swarm for Battlefield Mapping using System Modeling Language. The design of the developed battlefield SoS will utilize standard Systems Engineering processes, adapted Systems Engineering processes for Systems of Systems, and architecture representation models. Each of these key utilities will be analyzed to provide guidance and considerations for SoS Engineering of the UAV Swarm.

Increasing penetration of wind power has led power system operators worldwide to develop new grid codes for integration of a wind power plant (WPP) onto the grid. According to the grid codes issued by Federal Energy Regulatory Commission (FERC) in the US, a WPP must have low voltage ride through (LVRT) capability, power factor design criteria, and supervisory control and data acquisition (SCADA) system to ensure power system reliability. Fast Fourier transform (FFT) is frequently used to measure root mean square (RMS) voltage, power factor, and for supervisory data acquisition in order to verify that a WPP conforms to the grid code requirements. However, FFT inherently assumes signal is periodic in nature, and it provides misleading results under unbalanced and distorted grid conditions. To overcome these issues, this work proposes a new method for wind power grid codes based on time-frequency analysis technique. Unlike FFT, it provides accurate result both in steady-state and transient conditions. The efficacy of the proposed method is verified by applying it to computer simulated and real-world cases provided by National Renewable Energy Laboratory (NREL) in the US. Time-frequency analysis is performed utilizing Time-Frequency Toolbox (TFTB) in MATLAB R developed for the analysis of non-stationary signals. INDEX TERMS Fast Fourier transform, grid codes, power systems, time-frequency distribution, wind power.
