Development of Advanced Electric Vehicle with Driving Range of 333 KM by Japanese Start-up Company
A Japanese Start-up company by name of SIM-Drive Corporation has successfully developed an electric vehicle (EV) with a driving range of 333 KM per charge. The new EV with nickname of SIM-LEI, where LEI stands for Leading Efficiency In-Wheel motor, achieves this target using 24.5kWh capacity Lithium-ion (Li-ino) battery. However, the fundamental technologies contributing to this high performance are company’s original technology such as in-wheel motor as well as built-in frame.
In addition to these technology, steel monocoque body has resulted in reduced body weight and super low rolling friction resistance tire contributed to reduced friction resistance, plus the super low air drag body has reduced the drag drastically. The AC electrical power consumption rate on the SIM-LEI is at 77Wh/km, which is equivalent to 70km/L of the fuel efficiency rate on gasoline run automobiles. The SIM-Lei achieves a 4.8 seconds 0-100 km/h standing start acceleration. The vehicle comes in dimension of 4700mm x 1600mm x 1550mm, weighing 1650 kg, and a maximum speed of 150 km/h. In addition to all these benefits for those of us who choose not to use their EV during the day, it can be plugged in at night for storing electricity to be used for household use during the day, a perfect solution for energy shortage during the peak hours, which by the way is the most expensive time. Company is planning to put the SIM-LEI into full production by 2013. It would be interesting to see the price tag no these new nifty EVs, when they hit the market, where it opens up a huge competitive ground with local incumbents.
