With the widespread application of electric vehicles, study power lithium-ion battery (LIB) has broad prospects and great academic significance. The state charge (SOC) is one key parts in management system (BMS), which used to provide guarantee for safe efficient operation LIB. To obtain reliable SOC estimation result under influence simple model measurement noise, a novel method with adaptive ...

This study investigates the influence of considered Electric Equivalent Circuit Model (ECM) parameter dependencies and architectures on predicted heat generation rate by using Bernardi equation. For this purpose, whole workflow, from cell characterization tests to identification finally validation studies, is examined a cylindrical 5 Ah LG217000 Lithium-Ion-Battery (LIB) with nickel manganese c...

It is crucial to conduct highly accurate estimation of the state charge (SOC) lithium-ion batteries during real-time monitoring and safety control. Based on residual constraint fading factor unscented Kalman filter, paper proposes an SOC method improve accuracy online estimating SOC. A priori values terminal voltage were fitted using cubic Hermite interpolation. In combination with Thevenin equ...

Power Li-ion batteries are one of the core three powers systems new energy vehicles, and its accurate modeling state prediction have become technology scientific technological progress in industry. This paper takes ternary as research subject. Aiming at mathematical expressions different structural features, innovatively construct a second-order Thevenin equivalent circuit model with autoregres...

This paper proposes a new equivalent circuit model for rechargeable batteries by modifying double-capacitor proposed in [1]. It is known that the original can address rate capacity effect and energy recovery inherent to better than other models. However, it purely linear includes no representation of battery's nonlinear phenomena. Hence, this work transforms introducing nonlinear-mapping-based ...

Bu çalışmada, çok baralı bir güç sisteminin herhangi yük barasından görülen Thevenin empedansı ve kullanılarak barasına gerilim kararlılığı değerlendirmesi yapılmıştır. Gerilim analilizi yapılacak baradan eşdeğer devre optimizasyon esaslı yaklaşımla hesaplanmıştır. Optimizasyon yaklaşımı için yerel sadece akım, faktörü ölçümleri Hesaplanan baradaki yükün ile baraya ait empedans kararlılık indek...
