~1.6 Mio. Units Hybrids and Electric vehicles sold in 2012 worldwide!
~1.4 Mio. units were Japanese brands!
~900 000 units sold in Japan!
Japan is the biggest producer and consumer
market for Electric vehicles & Hybrids
5 Hiroshi Shimizu
Why Japan was successful in the field of Electric vehicles and Hybrids ?
Japanese people have suffered from big air pollution in 1960’s and damaged economically by oil shock in 1973
Fundamental research and development activities (science and industry) have been done continuously from 1970’s supported by the government
Decision of car OEMs to go for EVs and HEVs
People’s mind, fundamental research and decisions of industry & government were combined together at an early stage
5
Government, OEMs and Suppliers all played a vital role with their efforts in the early stage

Realize by the performance of components and the structure of the vehicle.
Easy to drive & Comfort
Highest Driving Performance
Long enough Range per Charge
The value of outstanding electric vehicles
everyone want to buy
10 Hiroshi Shimizu
Which technology will survive ?
Other Key Success Factors have to be met
Consumer orientated - usability, service etc. Production orientated - low production costs, easy to make etc. High efficiency - running costs, energy consumption etc.
Technologies succeeded as a combination of these factors: LCD display (against plasma), ICE & TGV against Linear Magnet
10
Not necessarily the “best” technical solution survives!

12 Hiroshi Shimizu
Future trend of Electric vehicles.
Li-Ion Battery, Ne-Fe Magnet, IGBT invented and developed so far are enough to realize the high-performing EV
12
The evaluation of technology shows that currently EVs with range extender seems to be most promising.
In-wheel motor has a 30 % higher efficiency than the conventional drive system.
Only considering optimization of total drive system will create
the best electric vehicle

What is the next step of electric vehicles ?
Avoid accidents and traffic jam.
Save the time for traffics.
Everyone can go anytime and anywhere.
15
The automated driving. Electric vehicles should be driven without drivers.
16 Hiroshi Shimizu
Final Target
Developing the next generation vehicle – High performing and environmental friendly – Capability have to enough to be accepted in the society
Distribute the vehicle to all over the world
People in the world should have comfortable mobility and sustainable environment
Collaboration among all the people in the world are the key of developing mobility for the global future
