英文要約R&D of Practical and integrated Energy storage systems for smart community/
elemental technology development/Development of Energy Storage EMS at Commercial Building Essential for Smart & Compact Community
For fiscal year 2010, we have targeted our development for BEMS (Building Energy Management System) by gathering, visualization and analysis of energy consumption data from commercial facilities in our field test building. Our BEMS started on gathering and measuring energy consumption data through digital meters. Currently, we measure energy consumption of lightings, air conditioners and refrigeration facilities, which are estimated to be 80% of the total building's energy consumption. Energy consumption data are transferred to a management server in BEMS for visualization and analysis of energy consumption patterns for the building. "View" designs for visualization and analysis of data in the management server is already completed. Actual development/programming of "views" will be finished in first quarter of fiscal year 2011.
Specification of demonstration facilities to develop energy storage EMS at commercial building essential for smart & compact community has been designed. Demonstration facilities consist of photovoltaic facility, energy storage facility (Lithium ion battery and advanced lead battery) and load system such as lighting facility, HVAC equipment, refrigerated facility and EV charger. The vendor selection has been considered in terms of cost and capability. Installation location of these equipments has also been decided. These equipments installation and construction of demonstration facilities will be completed in first half of the fiscal year 2011. Demonstration test will be started in second half of the fiscal year 2011.
For the purpose of improving SOC property, SOP property, calendar life property and cycle life property, it is essential that we find out charge and discharge voltage limitation and measure lithium ion battery capacity/ voltage/ internal resistance at each charge and discharge condition. We have been preparing charge and discharge tests varying each condition such as temperature condition, current condition, degradation condition and SOC condition.
A lithium ion capacitor-battery combined electric power storage device has been designed and main parts of lithium ion capacitor modules, lithium ion battery modules, and DC-DC convertors have been manufactured. A system energy flow simulator has been completed by adding an electric vehicle battery imitation, also partly prepared some installations.
