The Li-Ion equipped Mitsubishi iMiEV w/ a range of 100 + miles on a single charge is advancing the future of transportation in Japan.

Kanagawa Prefecture, Japan which includes the cities of Yokohama and Kawasaki has started a program to promote the introduction of EV’s. As an Irishman living in Kanagawa, this took me a little by surprise. The program has set a goal of 3,000 EV’s or .1% of the current vehicle population on the road within 5 years and seeks to establish 150 fast recharge centers throughout the area. As a further incentive, the district will reduce parking charges for EV’s at public parking facilities and they will receive decreased toll charges on Japanese highways.

Kanagawa Prefecture has organized events to introduce the benefits of EV’s to the public with test drives of Li-Ion powered vehicles including the Subaru R1e and Mitsubishi iMieV. They have formed a working group between automotive makers including Nissan, Mitsubishi and Fuji Heavy Industries (Subaru), electric utilities including Tokyo electric power company (TEPCO), battery manufacturers including NEC Lamillion, GP Yuasa and Ministry of Environment as well as Universities and Fleet users.

TEPCO has previously announced a program to replace approximately 3,000 vehicles in its fleet with EV’s. It is currently testing 10 Subaru R1e’s and 1 Mitsubishi iMieV. It has developed a fast re-charger and the EV’s under evaluation are fast recharge capable from 0 to 80% SoC in 15 minutes or less. Both Subaru and Mitsubishi, have developed EV’s for this program based on their popular 660cc, Kei class series and will be competitively priced at approximately 1.5 million Yen or $12,000 US. The Kei class of automobiles currently hold 40% of new car market in Japan. With their high fuel economy ratings, they are a major reason for the current decrease in gasoline consumption throughout all of Japan.

As part of a New Energy Strategy 2006, the Japanese government has set up a program to reduce rechargeable battery costs to half by 2010, 1/7th by 2015 and 1/40th by 2030 of current levels as this is considered to be a major impediment to electric vehicle introduction. Although high volume Li-Ion cells are available for laptops, large format Li-Ion cells best suited for EV applications have not been mass produced. The traditional single track scenario was to use fuel cell vehicles with an expected market penetration of 50,000 by 2010. Battery technology is now considered to be the key for all next generation vehicles in Japan.

As battery costs continue to decrease with increasing manufacturing volumes from both the Kanagawa and TEPCO programs, placing EV’s on the road is a first step in the right direction A comparison of the performance goals for both EV’s are shown below. The goals listed for the models under evaluation are minimums with even better performance expected for the actual vehicles once introduced. As we all know from gasoline ICE vehicles, Your Range May Vary (YRMV) ;)

Only $11K for a 4-seat and streetable mini Electric Vehicle with 100 miles range? Where do we sign up!

Holy cow!! I want one of those!! :eek:

That's awesome, and thanks for a peek inside a culture that's
genuinely interested in solving the problem at the administrative
level! It's going to take that kind of mandates over here to
crack people loose from their lethargy and get 'em moving. Just
like the aggressive, get-it-done goals that Toyota set when
developing the Prius, they're going hard after developing the
right technologies and it sounds like they're not going to let
outfits like Cobasys stand in the way of progress. A society
where lawyers can defend the concept of making something BIGGER
with patents and licensing is just totally out of line.
.
Oh, and I assume people aren't expecting neck-snapping
acceleration out of these vehicles, right??

The iMiEV seems pretty impressive for such an inexpensive car. It seems to me that Mitsubishi is hoping its future EV sales will bring itself back into being a profitable company.

Wow, sounds great. I was wondering when the BEV's would start showing up mainstream in Japan.

Not to be redundant, but man, sounds great.

100 mile range is all I need. I could go to work and do errands easy.

This is a link to JAF, Japan Automobile Federation article in Japanese, but the pictures are of the i MieV, notice the fast charge(left) and household(right) connectors.

Keep dreaming...as much as you would for any kei car in the US. :(

Wow.
I commute 60 mi. each way to a regional power company - I could drive one of these if they let me plug in while at work.

Now let's see, do you think Detroit is going to try keep these out of the U.S.?

They seem pretty serious, running a commercial on Prime time TV.

Totally cool. Electric cars were once a big lemon of an idea. But the advancement of the battery is making this a reality. All we need now is an increase in efficiency for solar panels and we will be laughing! :Banane06:

Wow, how cool. These are the perfect second or third car at home. Actually, other way around, I'd have one of these for everyday driving and a Prius for longer trips :)

The reason they are getting of the ground in Japan is because even the regional government sees the possibilities, building charging stations and stuff. I wish we could get these things here :(

That body style doesn't look very aerodynamic. If most of your driving was highway, I bet you could increase both the range and the max speed (if the gearing allows the higher RPM's) by about a third by aero modding it.

Just an update, the Subaru R1e fast recharge performance has been improved.
8 minutes to reach 90% SOC to allow 72km on one fast charge.

http://www.greencarcongress.com/2007/09/fuji-heavy-spee.html#more

To be on the safe side, I am looking for an EV that can do a round trip commute of 140-180km but now a few fast charge stations on my commute and even the R1e looks promising.

Good Luck
Andrew
