Mitsubishi Motors builds "i MiEV" for joint research with power companies
Mitsubishi Motors Corporation (MMC) has built a new research vehicle, the Mitsubishi innovative Electric Vehicle (MiEV) (*1) for a next-generation EV development project. The electric vehicle (EV) will be used for joint research programmes with power companies that have been working on the promotion of EVs. The power companies will conduct field tests, gather data and evaluate the commercial viability of the vehicle. Mitsubishi will provide power companies with EVs and analyse field test data collected by them.
The new research EV is based on Mitsubishi's "i" mini-car, and named "i MiEV". i MiEV is powered by a compact and lightweight motor and high-energy density lithium-ion batteries. After removing the i's combustion engine mounted on the platform with an original rear-midship layout, a single motor (*2) is mounted in its place. i MiEV became electric-powered with few modifications of the body structure. In addition to the joint research programmes, Mitsubishi will further improve the components of i MiEV such as the battery system, motor and EV electronic control unit for the future commercial application.
(Mitsubishi will display i MiEV at the 22nd International Battery, Hybrid and Fuel Cell Electric Vehicle Symposium & Exposition (EVS-22) at Pacifico Yokohama in Yokohama on October 23 - 28, 2006.)
Mitsubishi will begin joint research with Tokyo Electric Power Company, and The Chugoku Electric Power Co., Inc., in November 2006 and with Kyushu Electric Power Co., Ltd., in January 2007. MMC will provide each power company with i MiEVs. By testing i MiEV, the power companies will evaluate how the vehicle is applied to their business and how fast-charge infrastructure may be developed for EVs.
In the autumn of 2007, Mitsubishi will begin fleet testing in order to verify the vehicle's technical capabilities in daily use and to evaluate the commercial acceptance in collaboration with the power companies above along with, the Kansai Electric Power Co., Ltd., and Hokuriku Electric Power Company. Mitsubishi will provide the power companies with i MiEVs for the fleet tests. The data collected from the test of daily use shall be used to assess the commercial viability of EVs in the market place.
Mitsubishi takes environmental concerns seriously. Developing new environmental technologies and diversification of fuel sources are Mitsubishi's key challenges and the MiEV project is an approach to these. Mitsubishi is also working on other environmental technologies such as clean diesel engines and bio-fuel engines. On the social side, Mitsubishi launched a natural conservation project called the "Pajero Forest & Local Mountain Restoration Initiative", which supports conservation and management of Japan's forests.
*1 "MiEV" encompasses Mitsubishi's whole technological concept of lithium-ion battery, in-wheel motor and other technologies related to EV, hybrid electric vehicle and fuel cell vehicles. The MiEV concept is developed from MMC's former concept "Mitsubishi In-wheel motor Electric Vehicle (MIEV)", referring to a lithium-ion battery/in-wheel motor-driven vehicle. Mitsubishi continues to develop in-wheel motor technology.
*2 In this system a single electric motor is coupled to a reduction gear and differential to drive both rear wheels.
