Abstract
Recently it is required to shift consumer society to Recycling-based Society. Therefore we proposed a concept for the product upgrading by adopting the new environment-friendly technology without wasting its life. In this study we aim to prove the effectiveness for the protection of the environment and the resource with that concept. In this report, we upgraded the regenerative braking system of an electric vehicle that converted from an internal-combustion vehicle. As a result, the drive range by one time charge increased 20.6%, and it became 103.1km. And compared with the internal-combustion vehicle, our EV reduced 40% of CO_2 and 20% of NO_2.
