Luxury electric sports car The New Tesla Roadster with green machine, Electric, Fantastic Efficiency Car (not need Fuel gasoline just electric for run this car).Electric cars just don't have to be as complex mechanically as the car you're probably driving now. Sophisticated electronics and software take the place of the pounds and pounds of machinery required to introduce a spark and ignite the fuel that powers an internal combustion engine.For example, the typical four-cylinder engine of a conventional car comprises over a hundred moving parts. By comparison, the motor of the Tesla Roadster has just one: the rotor.
The engine and transmission of a conventional car also need lubricating oils, filters, coolant, clutches, spark plugs and wires, a PCV valve, oxygen sensors, a timing belt, a fan belt, a water pump and hoses, a catalytic converter, and a muffler — all items requiring service, and all items that aren't needed in an electric car.
Sport car Tesla Roadster's elegantly designed powertrain consists of just the four main components:
Tesla Roadster Energy Storage System (ESS):
Tesla battery pack ( the car's "fuel tank") represents the biggest innovation in the Tesla Roadster and is one of the largest and most advanced battery packs, it's heavy, expensive, and offers limited power and range, combined basic proven lithium ion battery technology, with unique battery pack design to provide multiple layers of safety. It's light, durable, recyclable, and it is capable of delivering enough power to accelerate the Electric Tesla Roadster sport car from 0 to 60 mph in under 4 seconds.
Motor
More important than the motor's size or weight is its efficency. Without proper efficiency, a motor will convert electrical energy into heat instead of rotational energy. So Tesla designed the motor to have efficiencies of 85 to 95 percent; this way the precious stored energy of the battery pack ends up propelling you down the road instead of just heating up the trunk.
Transmission
Sport car Tesla Roadster transmission couples the fuel efficiency of a manual with the driving ease of an automatic. The Tesla Roadster has only two forward gears, allowing you to fine-tune your driving experience (but either gear will work for most driving scenarios). Unlike a manual transmission, the car will not stall if you have it in the wrong gear. There's also no clutch pedal. Just move the lever and the electronic control module takes care of the shift, so you can launch from a full stop to freeway speed without taking your focus off the road, your foot off the accelerator, or your hands off the wheel.
Power Electronics Module (PEM) :
Most of the subsystems in the Tesla Roadster Sport car are completely electronic and under direct software control. But unlike all other cars, these systems are not a hodge-podge of independent systems — instead, they are designed as an integrated system, the way complex network and computer systems are designed today.
See the hub of this network every time you pop the trunk — the Power Electronics Module. When you shift gears or accelerate in the Tesla Roadster, the PEM translates your commands into precisely timed voltages, telling the motor to respond with the proper speed and direction of rotation. The PEM also controls motor torque, charging, and regenerative braking, and it monitors things like the voltage delivered by the ESS, the speed of rotation of the motor, and the temperatures of the motor and power electronics. The Tesla PEM controls over 200 kW of electrical power during peak acceleration , enough power to illuminate 2,000 incandescent light bulbs.
