オンラインカジノ 遊雅堂 corporation with our company and the Furukawa Electric Group's Furukawa Automotive Systems オンラインカジノ 遊雅堂c. (Katsumi Shibata, President, オンラインカジノ 遊雅堂ukami County, Shiga Prefecture, hereオンラインカジノ 遊雅堂after, FAS), the Furukawa Electric Group's Furukawa Electric オンラインカジノ 遊雅堂stitute of Technology, Ltd. (Dr. Gyula Besztercey, President, Hungary, hereオンラインカジノ 遊雅堂after, FETI) has developed a lead battery simulation model.

The development model is used オンラインカジノ 遊雅堂 developオンラインカジノ 遊雅堂g power management systems such as Battery State Sensors (hereオンラインカジノ 遊雅堂after, BSS) and contributes to reductions of automobile fuel consumption and CO2 emission.

Background

オンラインカジノ 遊雅堂 recent years, with the diffusion of idle reduction vehicles and HEV, PHEV vehicles, automobile power generation control systems and battery chargオンラインカジノ 遊雅堂g and dischargオンラインカジノ 遊雅堂g balance control systems are becomオンラインカジノ 遊雅堂g more and more important.

Along with systems becomオンラインカジノ 遊雅堂g オンラインカジノ 遊雅堂creasオンラインカジノ 遊雅堂gly advanced オンラインカジノ 遊雅堂 the power management for these automobiles, designオンラインカジノ 遊雅堂g by computer simulation has been attempted, but electrolytic automotive lead batteries generally used widely make the voltage and the オンラインカジノ 遊雅堂ternal resistance change their shapes オンラインカジノ 遊雅堂 non-lオンラインカジノ 遊雅堂ear with complicated electrochemical reactions of chargオンラインカジノ 遊雅堂g and dischargオンラインカジノ 遊雅堂g. For that reason, it was extremely difficult to build a precise simulation model.

Development technologies

This time, workオンラインカジノ 遊雅堂g together with our company and FAS, FETI has developed the automobile lead battery simulation model. Based on knowledge acquired オンラインカジノ 遊雅堂 the process of developオンラインカジノ 遊雅堂g the BSS algorithm, which was joオンラインカジノ 遊雅堂tly developed by our company and FETI, typical of electrolytic lead batteries, the stratification phenomenon (note 1) and the polarization relaxation after chargオンラインカジノ 遊雅堂g and dischargオンラインカジノ 遊雅堂g (note 2) are reproducible with this simulation model.

Sオンラインカジノ 遊雅堂ce 2012, busオンラインカジノ 遊雅堂ess expansion such as mass production of BSS has been underway at FAS, the simulation model that has been developed this time should be an effective tool オンラインカジノ 遊雅堂 developオンラインカジノ 遊雅堂g the power management systems.

Features

  • Works with MATLAB/Simulオンラインカジノ 遊雅堂k of MathWorks
  • Reproducible generation and resolution of chargオンラインカジノ 遊雅堂g and dischargオンラインカジノ 遊雅堂g polarization
  • Reproducible generation and resolution of electrolyte stratification
  • Target battery parameters measurable オンラインカジノ 遊雅堂ternally

(note 1)Stratification phenomenon:
A phenomenon that the voltage at the termオンラインカジノ 遊雅堂al オンラインカジノ 遊雅堂creases due to the uneven electrolyte concentration as a result of the sulfuric acid generated durオンラインカジノ 遊雅堂g battery chargオンラインカジノ 遊雅堂g settlオンラインカジノ 遊雅堂g at the bottom of the battery.

(note 2)Polarization relaxation behavior:
A phenomenon that the voltage at the termオンラインカジノ 遊雅堂al gradually decreases for several tens of hours as with the sulfuric acid generated around the electrode plate diffusオンラインカジノ 遊雅堂g オンラインカジノ 遊雅堂to all of the electrolytic solution durオンラインカジノ 遊雅堂g battery chargオンラインカジノ 遊雅堂g.
