Directions for Vehicle Using System Aiming at a Long Life : Performance Evaluation of Convert EV, and a Battery Degradation Diagnostic Examination Which pointed to "up-grading"

Abstract

In this study, we have suggested the concept of "up-grading" product that can improve the performance and aim at a long life for the construction of the sustainable society. At that point, we converted the gasoline car into the electric vehicle (EV). we showed the effectiveness of driving at high-speed and the drive pattern that there are much stop and departure on produced convert EV. And the environmental load can be reduced by driving the convert EV more than 7000km. From the point of management of the parts life, we experimented the deterioration of the butteries on EV, we showed that the voltage and the current change were different according to the deterioration situation.
