ecocar car : Electric Car Uses Bumps to Charge Battery

This strange looking car is an interesting concept designers, industrial Kim Jung Hoon was a record year for the 2010 Michelin Challenge Design competition. Unlike other electric cars, which is connected in particular in relation to the charging station or an extension cord, Eco-P has four piezoelectric devices to recharge the battery when the car is moving.

Kim thought the P-Eco, that the car is a lot of energy that can be collected and converted to lose. Whenever the vehicle is in motion, and vibration is reflective and could be used piezoelectric device to generate power that can recharge the battery. Piezo on both sides of each seat, this concept car can not be operated effectively without additional costs for electricity or gasoline.

Car, of course, the need for other energy sources, such as backup, especially if it is not used for some time. But it would be fairly easy to draw, and the batteries to charge only in the home network, and then keep moving car while on the road. Concept is based on the future effectiveness of the piezoelectric based, it makes sense, I know, but now will one day produce uneven road, it was really good.

Concept Car : BMW Vision EfficientDynamics 2010

For decades, BMW has made the reduction of emissions and fuel consumption a key part of its product development strategy, just as enhancements to the dynamic ability of each BMW have been a lasting, sustained brand value. BMW’s EfficientDynamics engineering philosophy – the pursuit of an enhanced, athletic driving experience while simultaneously lowering the consumption and emissions of each vehicle – resulted in the most dramatic drop in fleet consumption of any automaker from 1990 through 2005, according to an Environmental Defense study.

Now, the BMW Vision concept car clearly demonstrates that the EfficientDynamics objectives are fully compatible when applied to a sports car. Conceived as a 2+2-seater with plug-in full-hybrid technology, this unique car combines the performance of a BMW M vehicle with a standard of fuel efficiency and emission management that exceeds even the current levels achieved by the latest small cars. This outstanding result is made possible by the combination of BMW ActiveHybrid components with an extremely economical combustion engine, and outstanding aerodynamic qualities.

BMW Vision EfficientDynamics is the result of a “clean-sheet” development process to ensure that the correct achievements were made in the areas of efficiency, driving pleasure, technology, and emotional design. BMW Vision EfficientDynamics is the most comprehensive implementation of the EfficientDynamics philosophy seen so far. The powertrain provides a top speed limited electronically to 155 mph, with acceleration to 100 km/h in 4.8 seconds. Average fuel consumption in the EU test cycle is 3.76 liters/100 kilometers, equal to 62.6 mpg, and the CO2 emission rating is 99 grams per kilometer. CO2 emission management is even more outstanding when driving in the all-electric mode after charging the battery from a plug-in source: Taking all emissions in the generation of electricity into account, as prescribed by the EU formula, the car’s emission rating is just 50 grams per kilometer.

Through this unique balance of driving pleasure and fuel efficiency, the BMW Vision EfficientDynamics concept car clearly demonstrates the potential of BMW ActiveHybrid technology, which makes its world debut at the 2009 Frankfurt Motor Show in the BMW ActiveHybrid X6 and BMW ActiveHybrid 7 production models.

The power and performance are made possible by combining a fuel-efficient 3-cylinder turbodiesel with one electric motor on each axle. The intelligent combination of these units, together with precisely controlled energy management, simultaneously enhances the dynamic performance and the efficiency of the car. Overall system output is 356 horsepower, and peak torque is 590 lb-ft. The special arrangement of the two motors and diesel engine allows all-wheel drive when driving in all-electric mode. The result is minimum power loss and a harmonious transmission of the power available under all conditions.



In its design, BMW Vision EfficientDynamics for the first time conveys the dynamic look of a BMW sports car to a hybrid vehicle. Developed with decades of experience in Motorsport, the body of this unique sports car is a result of intelligent lightweight technology and aerodynamic efficiency. In the design of the interior, the focus was likewise on both the fascinating driving experience and, in particular, on transparent, hands-on technology and maximum reduction of weight.



Turbodiesel engine with unprecedented specific output



The combustion engine is a cutting-edge turbodiesel featured for the first time in the BMW Vision EfficientDynamics concept car. Displacing 1.5 liters on three cylinders, the engine consistently follows the downsizing principle of using a relatively small engine combined with a turbocharger to reduce fuel consumption.



Through its compact dimensions, the 3-cylinder fits conveniently in front of the rear axle like in an agile mid-engine sports car, despite the two seats at the rear. Fuel is injected by the latest generation of High Precision Direct Injection, and the turbocharger features variable intake geometry for maximum efficiency. Engine output is 163 hp with peak torque of 214 lb-ft.



The specific output of 109 hp per liter sets a new benchmark in diesel technology. The power delivered by the turbodiesel is conveyed to the rear axle by means of a double-clutch transmission (DCT). This advanced transmission technology, which already offers a particularly dynamic driving experience in BMW’s M3 and Z4 Roadster, allows the driver to shift gears without the slightest interruption of power. BMW Vision EfficientDynamics features a newly-developed version of BMW’s DCT with six speeds for maximum efficiency and flexibility.



Two electric motors for full-hybrid drive

The combustion engine is supplemented by two electric motors. Consistently applying the BMW ActiveHybrid philosophy, development engineers followed the principle of “Best of Hybrid,” choosing the optimum combination of a hybrid synchronous motor on the front axle and a full-hybrid system at the rear.



In this concept, the driver benefits from the efficiency of the electric motors over a far wider speed range than with a conventional hybrid car. The rear axle comes with a second-generation full-hybrid system corresponding to the technology in the BMW ActiveHybrid 7 production model. The compact electric motor positioned between the diesel engine and the DCT outputs a consistent 33 horsepower and is able to reach a peak of up to 51 hp. Maximum torque for the rear electric motor is 214 lb-ft, the power, either supporting the diesel engine or in all-electric motoring. When coasting or applying the brakes, the electric motor acts as a generator and feeds electric power to the lithium-polymer battery in the car. The electric energy developed in this way is therefore captured without any additional consumption of fuel through the principle of Brake Energy Regeneration. Energy wasted on the brakes of a conventional car is thus saved within the new power system for subsequent use in driving the car.



A second electric motor acts on the front axle. This engine, a hybrid synchronous motor, offers continuous output of 80 horsepower and peak torque of 162 lb-ft. Extra power of 112 horsepower is available for a period of up to 30 seconds, and, for a 10-second “burst,” the electric motor is able to develop 139 horsepower. The power is transmitted through a 2-stage, single-speed reduction gearbox.



BMW Vision EfficientDynamics is able to run completely under electric power, with the power of the turbodiesel engine alone, or through an infinite combination of the three power sources. Depending on driving conditions, the two electric motors may be used both for accelerating and for regenerating energy when applying the brakes and while coasting. This principle ensures efficient energy management, with the charge status of the lithium-polymer battery constantly remaining within the optimum range. When accelerating, the electric motors help to boost the car for even greater performance, ensuring immediate response and a significant reduction in fuel consumption. For a short time, such as in passing maneuvers, the cumulative maximum output of all three engines increases to 356 hp, with maximum torque generated by the three engines reaching 590 lb-ft.

Lithium-polymer battery for electrical energy



The energy cells featured in BMW Vision EfficientDynamics are housed in a chassis element running from front to rear through the middle of the car. The front unit is the lithium-polymer complex, an ongoing development of the lithium-ion battery. Overall, BMW Vision EfficientDynamics comes with a total of 98 lithium-polymer cells, each offering a capacity of 30 amp/hours and developing continuous output of 600 Amps at a voltage of 3.7 V. For a period of 30 seconds, each cell is even able to develop maximum output of 1,200 Amps.



Serial arrangement of the lithium-polymer cells serves to generate nominal voltage of 364 volts, the gross storage capacity of the battery is 10.8 kW/h. With an unusually high discharge capacity of 80 percent, the battery delivers 8.6 kW/h for driving the car. This superior performance comes on overall weight of the entire energy storage system of just 187 lb. A further advantage is that through their optimum dimensions tailored to the specific qualities and features of the car, the lithium-polymer cells, together with the operating strategy chosen with a concept of “forward looking” energy management, reduces the thermal load acting on the battery to such an extent that there is no need for active cooling.



Plug-in solution: convenient charging of the electric power system from a conventional power socket.



Brake Energy Regeneration captures electric power generated while driving without additional fuel consumption, which is subsequently used to supply power to the electric motors and on-board network. A further option is to connect the lithium-polymer cells to a conventional power socket for a simple and efficient charge process, using a plug-in connector in the front-right wing of the car. Connected to a standard EU power outlet (220 V, 16 Amps), the system requires a maximum of 2 ½ hours to fully charge the lithium-polymer cells. And wherever a power source with higher voltage and amperage (380 V, 32 Amps) is available, the charge time is an even shorter 44 minutes.

Concept car : Volvo S60 2010

 

A few weeks ago we brought you the first hint of Volvo's new S60 concept car and here are the first images of the vehicle that will be unveiled at the Detroit Auto Show in early January 2009. The Concept gives an indication of what the all-new Volvo S60 will look like when it's launched in 2010. The coupe-inspired lines that gave the original S60 its characteristic stance are more pronounced in this next generation.

"The concept car's exterior gives a clear indication of what customers can expect of the all-new S60. On the inside we've been even more daring," says Volvo Cars Design Director, Steve Mattin.

The front of the S60 Concept sports the enlarged iron mark in the trapezoidal grille. The two lamps that flank the grille emphasize the vertical stance of the front, highlighting the hood's V-shape. The angled headlamps flow into the sculptured hood and, combined with the lower air intake's reverse trapezoidal shape, gives the concept car an expressive "face".

Viewed from the side, the concept's slim coupe roofline and windows are accompanied by an entirely new shoulder line, forming a gentle double wave from the headlamps to the rear. Both the seven-spoke 20" wheels and the tread of the low-profile tyres have been specially designed, while the bronze brake calipers match the `Warm Liquid Copper' paint on the car.

The unique rear parallelogram doors offer a spectacular show when opened or closed. Door opening is initiated by pressing a button and the movement starts in the traditional way. In the next phase, the forward section swings away from the body and the door glides parallel with the side of the car until it reaches its end position by the rear wheel.
