The SMERA is now ready to commute into the urban and out-of-town traffic. Originally designed to shift and park with ease, the SMERA has a dreaming size: 86 cm width and 2,50 m length.
Do not suffer traffic jam or bad weather, park easily and safely drive.
The SMERA opens a new way of mobility. LUMENEO is currently working on the M1 European homologation for the SMERA. This car homologation is the first one for such innovative vehicle, final certificate will allow to drive on all European roads.
After several exhibitions where the SMERA has been presented, we have collected visitors' suggestions. This final version offers to the driver and his passenger more inside roominess.
For this first year of production, Lumeneo plans a progressive start. In 2011, rhythm will increase to match the French and European demands.
Entirely electric, a car driving licence is compulsory to drive the SMERA.
The alliance of aestheticism ...
A VERY URBAN LINE
Purity and delicacy of lines have guided the hand of the SMERA designers. With its only 86 cm of width and 2.50 m of length, the SMERA has an exclusive size to slip into the traffic and park without constraint. Its very fluid lines are emphasized by its automatic tilt in curves.
Getting onboard is easy, thanks to two large lateral doors. It allows getting in by the right or the left side, up to the place of parking. The SMERA has an aluminium protective 3D frame and a closed body. Seat belts and crash box complete the passive safety.
Five colours are available, but the choice of a specific colour is always possible.
A PREMIUM ONBOARD
Inside, the visibility is maximal with a wide glass surface which provides a panoramic view on traffic. The driver is comfortably held in his leather seat, protected by his seatbelt, without helmet. His seat can be fold away to let the passenger get in the back seat. Cockpit includes a LCD screen which displays all intuitive commands. The SMERA has a trunk which can easily receive daily bags (attaché-case, shopping bags...).
...and technology.
One special features of the SMERA is its automatic tilting system, to fit the curves with a new sensation. The driver is taking care of nothing, the intuitive handling provides a real driving comfort.
In the heart of the SMERA, an electronic system manages all the parameters of the vehicle, starting from the signals provided by an integrated inertial system. According to the dynamic parameters of the car, the turning curves, the selected driving mode and the road quality, it determines the optimal tilting angle. It is a servomotor controlled by the calculator which fulfils the function automatically by moving the cabin and the four wheels.
ECOLOGICAL BY NATURE
Electric since its design, the SMERA is particularly ecological. Its operation generates no local pollution, no noise and no smoke. Its maintenance is minimal because electric motor have a very long life and its recycling is simple.
The SMERA is equipped with two electric brushless motors with permanent magnets for its propulsion, especially designed for this purpose. These motors offer a 1,000 Nm torque at the rear wheels from the start unlike thermal engines, where the maximum torque is only available at high speed.
Each motor weighs less than 30 Kg and is made up 98 % of pure metals, aluminium, copper and irons o its recycling is simple. It also avoids all the pollution created by a thermal engine: oils, catalytic exhausts, heavy metals.
The motors have been developed to answer precisely to the needs of the SMERA and to optimise the weight/power ratio. At Eeach braking action, the motors are transformed into an alternator to convert kinetic energy into electricity injected in the batteries, increasing the autonomy of the SMERA.
Brushless motors offer the main advantage to have no friction parts that makes it possible to have no maintenance and an excellent lifetime, nearly 200 000 km.
ELECTRICTY, ENERGY OF THE FUTURE
The energy source of the SMERA is a pack of batteries offering a 133 V tension and a 10 kWh capacity. Made of Lithium technology, these up-to-date elements meet all the needs of the SMERA. Thanks to its integrated charger and a 3 meters cable, the SMERA can be reloaded in all domestic plugs (230 V, 16 A).
The global awareness of the electric revolution will cause the multiplication of the charging plugs inside buldings, parkings and streets.
You just have to get a new reflex : plug it in the night and unplug it in the always have a 150 km maximum autonomy.
For this, the SMERA asks only for a 0,7 euro/100Km refill (standard cost French electricity). This means a 6 000 € saving for 100.000 km versus a thermal motorisation (of average consumption 5 l /100km).
The SMERA Lithium batteries are designed to operate at least 8 years, even if used every day.
AN ELECTRONIC COMING FROM AEROSPACE
From motors to wheels, a direct belt transmission is installed. The electric motors display a maximal torque when starting and deliver their power in such manner that it is not necessary to couple them with a gearbox.
The SMERA has two motor controllers and a central UC. They always work and the central UC supervises the controllers via a CAN bus, checking all results and calculation. In case of problem, the
central UC is acting as arbitrator, by adjusting the data. This architecture, already approved in aerospace, allows having a high reliability system. The electronic manages each millisecond the rates and the couples of the motors, so the SMERA can easily operate.
