英文要約Title : Development of high-performance battery system for next-generation vehicles (FY2007-FY2011) FY2010 Annual Report

I. Proposal of fundamental evaluation methods for characterization the battery total performance;
Specifications of newly developed advanced vehicles, including pure electric vehicles (BEVs), plug-in hybrid electric vehicle (PHEVs), and hybrid electric vehicle(HEVs), were surveyed for establishing technical requirements for the batteries. We proposed critical discharge capacities and power capabilities to determine battery life for these applications.

II. Development of accelerated life testing method by accelerating the battery degradation condition;
We have summarized the evaluation methods of batteries life. We determined a cycle life testing (CLT) profile induced by simplified the typical driving schedules.
Accelerating tests of proto-type practical-sized 10Ah-calss cells using the CLT profile have been continued at Akagi Testing Center of CRIEPI. Meanwhile, storage tests of the cells under various conditions, as parameters of surrounding temperatures and sate of charge (SOCs), have been continued.
Cycle Life Test Profile was proposed by JARI. Proto-type practical-sized 10Ah-calss cells CLT profile

III. Analysis of degradation effects mechanism and development of the technique for suppression control of battery degradation ;
We have developed various instrumental analysis techniques, including Fourier Transform Infrared-Attenuated Total Reflectance spectroscopy (FTIR-ATR), X-ray Photoelectron photoemission Spectroscopy (EPS), X-ray Absorption Fine Structure (XAFS), and in-situ Raman microscopy, to characterize battery active materials. Unique techniques, such as acoustic emission spectrometry and sum frequency spectrometry, also have been developed for fundamental research on fading mechanism of the materials using model cells. ;

IV. Development of evaluation methods of battery safety ;
The abuse tests of commercially available batteries for automobile application and proto-type practical-sized 10Ah-calss cells were carried out at Shirosato testing Center of JARI. Testing conditions effecting on battery endurance performance were summarized.

V. Codes and standards of performance estimation methods of batteries on next-generation vehicles ; JARI have been continued operating the four working groups (WGs) of "Battery Technology WG", "Battery Standard WG", "Battery Charging Standard WG", and "Battery Transport WG". In2010,IEC 62660_1+2 were established by IEC/TC21/JT69 through the JARI-WGs' activities.
