  • 본 논문에서는 Matlab을 이용하여 배터리의 전기적 모델과 내부 파라미터 추출 통해 시뮬레이션을 하였다. IR-drop에 의해 변화한 전압 데이터를 이용하여 부하 전류 변화로 인한 시뮬레이션과 실험 데이터 간의 오차 개선함으로써 배터리 전기적 모델과 실험 전압 데이터를 이용함으로써 확장 칼만 필터(extended kalman filter; EKF) 같은 적응 알고리즘을 사용하지 않고도 오차가 감소된 시뮬레이션이 가능함을 확인하였다.

  • Detailed expermental studies of theelectronic structure of the valence and conduction bands of the mixed conductor $\beta$-LiAlindicate that a quasi-gap opens at the Fermi level, and the conduction states are highlylocalized, as opposed to the theoretical band structure calculations that predict predominant metallic behavior. Evidence for complex lithium migration effects involving the surface of Lial , induced by particle (electron or ion) bombardment and mechanical treatment , has been obtained as a byproduct of these experiments.

  • The study on the hybrid power source for the IMT2000 application has been presented. The hybrid power source is composed of solar cell, super-capacitor and battery. To compensate for the pulse loader of the IMT2000 application, the super-capacitor is connected through the Lithium-ion battery to absorb the pulse current. The solar cell provides the additional current to compensate for the depleted current. The controller design for the hybrid source has been presented and verified through experiment.

  • A low-power design technique for lithium-ion Battery-Protection Integrated Circuit (BPIC) for multi cell configuration is proposed. The hardware sharing scheme with more precisely divided operating states in the detection range could reduce the power consumption significantly, especially during the normal state. The usefulness of the proposed scheme was confirmed through HSPICE simulations.

  • This paper presents a simulation model and analysis of grid-tied wind turbine generator with batteries using the PSCAD/EMTDC software. The modeled system is consist of two inverters and one bidirectional DC/DC converter. These inverter are to capture the maximum active power under varying wind conditions and to keep the DC-Link voltage magnitude at a specific level. And the bidirectional DC/DC converter makes battery charging or discharging depend on power gap between wind turbine output and local load. Aerodynamic models are applied for a wind turbine blade simulator.

  • Technical advances in manufacturing techniques and applied technologies have been made for bi cell manufacture, and are currently being implemented in the areas of discrete electrode / bi cell assembly, and electrode / separator lamination. Not only have improvements been noted in the reliability of the mechanical assembly and the increase in yields and decrease in costs, battery electrical performance has also been enhanced thru these assembly techniques. Evidence has been shown that the lamination techniques can influence porosity and electrolyte dispersion, and therefore electrical performance and long term reliability of the cells.
