  • construction of a three dimensional large scale shaking table and development of Core Technology
    Philosophical transactions - Royal Society. Mathematical physical and engineering sciences, 2001
    Co-Authors: Nobuyuki Ogawa, Keiichi Ohtani, Tsuneo Katayama, Heki Shibata
    Abstract:

    In 1995 the great Hanshin–Awaji earthquake disaster occurred in the Japanese city of Kobe and its vicinity, and more than 6000 people were killed as a result of the collapse of buildings. This was a clear demonstration of how very strong ground motion in the area near a seismic fault can cause severe structural damage beyond that which is usually estimated. It also emphasized the importance of earthquake engineering research in solving such problems as why and how structures collapse in real conditions. In response to this disaster, the National Research Institute for Earth Science and Disaster Prevention (NIED) and the Science and Technology Agency of the Japanese Government (STA) planned to build a three–dimensional, full–scale, earthquake–testing facility as one of the Core research facilities for earthquake disaster prevention. It is hoped to be able to carry large–scale structures and to simulate the process of dynamic collapse using three–dimensional, strong earthquake motion. For this purpose, the NIED and the STA began to develop large actuators and related components in 1995 and completed them in 1998. Through this development and testing, the design and manufacturing techniques of a large actuator system were successfully achieved. After that, the NIED and the STA began the design and construction of the new facility in the fiscal year of 1998. The construction work is now in progress in Miki City, near Kobe, Japan. It is scheduled to be completed by the beginning of 2005. In this paper, we summarize the performance and features of this new facility and the results of the technical developments.

  • ICTC - The CAN communication application on the BMS
    2013 International Conference on ICT Convergence (ICTC), 2013
    Co-Authors: Jeong-hyo Bae, Bai Zhiguo, Bong-jun Koo, Hong-ryoung Kim, Dae-gyeong Jang
    Abstract:

    In recent smart grid systems, the energy storage system (ESS) is known as a Core Technology. The Korean government faces an emergency. It must ensure reserve power because of the shortage of power in summer season. In 2013, the government began the AMI and ESS deployment projects to solve the problem of power shortage, allotting them a budget of 19.9 billion. ESS includes power management systems (PMS), power conditioning systems (PCS), battery management systems (BMS) and rechargeable battery systems. Among them, BMSs are Core Technology and are being developed globally. Therefore, we developed the BMS platform, based on a digital signal processing (DSP) platform, which is a Master-Slave structure. We adopted CAN communication Technology between the Master and Slave. The system is easily used to develop a new state of charge (SOC) and cell balancing technique. An interface that is able to communicate with other BMSs was added. Future research will continue the development of state of health (SOH) using the AC impedance method and the study of increased precision.

  • Battery management system by using CAN communication based on DSP platform
    2013 Fifth International Conference on Ubiquitous and Future Networks (ICUFN), 2013
    Co-Authors: Bai Zhiguo, Dae-gyeong Jang
    Abstract:

    In recent smart grid system of smart grid, ESS (Energy Storage System) is known as a Core Technology. Furthermore, because of the Fukushima Nuclear Power Plant accident in Japan and the 9.15 power outages in Korea in 2011 resulting in a lack of reserve power, development, demonstration and deployment of ESS are very popular in the world. Specially, Korea Ministry of Knowledge Economy has published K-ESS2020, which targets to be the Top 3 industrial countries of ESS and with a 30% global market share in the near future. In ESS, there are PMS (Power Management System), PCS (Power Conditioning System), BMS (Battery Management System) and Rechargeable Battery. Among them, BMS is the Core Technology and is being actively being developed in the world. Therefore, in this paper, we developed the BMS platform based on DSP (Digital Signal Processing) Platform which is a Master-Slave structure. We adopted CAN communication Technology between Master and Slave. This system allows for easier controllability and expandability. We also developed advanced SOC estimation and Cell Balancing function in our system.

  • acheulian giant Core Technology a worldwide perspective
    Current Anthropology, 2009
    Co-Authors: Gonen Sharon
    Abstract:

    The ability to detach large (larger than 10 cm) flakes from giant Cores and use them as blanks for the production of handaxes and cleavers is a technological hallmark distinguishing the Acheulian culture from its African predecessor, the Developed Oldowan, approximately 1.5 million years ago. Acheulian knappers applied a variety of fundamentally different, innovative, and sophisticated methods to large‐flake production that were perfectly suited to the size and shape of the naturally available raw materials. Yet the end products of all these methods were astonishingly similar across the geographical and chronological distribution of the Acheulian techno‐complex: large flakes that were suitable in size and morphology for the production of handaxes and cleavers.
