Tesla Roadster: The High Performance Electric Car

Now, Tesla is the world’s first high-performance electric car as a dreamed car for a lot of people. It is fast, fantastic and runs like a rocket shooting but it will never combust a single drop of gasoline. This way conserves our environment and provides the needs of consumers as well.
The Tesla Roadster can go a lot faster and farther than previous electric cars. The Roadster's estimated range is 250 miles on a single charge, at least 100 miles more than General Motors' EV1, which could go almost 150 miles under optimal conditions.

The Tesla Roadster is something different from a traditional gasoline-power car which is powered by just four main systems;
• The Energy Storage System (ESS)
• The Power Electronics Module (PEM)
• An electric motor
• A sequential manual transmission

The Tesla Roadster has been developed in a higher new technology of sport car that can run on the Energy Storage System (ESS). Tesla Roadster contains 6,831 of rechargeable lithium-ion batteries, (the technology proven in laptop field) in order to provide a fantastic performance. This makes us forget about gasoline-combustion engine in our current cars used. The batteries which provide four to five times the energy-density stores of other batteries, they are separated into 11 sectors with 621 each and all of them weigh 1,000 pounds. The efficient system of charging or discharging is controlled by a separated computer system in order to smoothly run the car. The car run up to the very high to peak speed by the electronic system which converts the DC power into AC power output by using 72 insulated gate bipolar transistors (IGBTs). This system is an efficiency of increasing much more power output than the first-generation electricity cars, a charging system and some other important functions which is called the Power Electronics Module (PEM). At the peak acceleration, the batteries can crank out 200 kW of energy -- enough to light 2,000 incandescent light bulbs.

The power Electronics Module’s functions are the charging and discharging system, the acceleration-detect control sensors, the voltage levels controlling, the motor's RPM (revolutions per minute), torque and the regenerative braking system. This braking system captures the kinetic energy usually lost through braking and transfers it back into the ESS. The efficiency and integration of the battery, PEM and motor systems is between 85 and 95 percent, allowing the motor to put out up to 185 kW of power. Aluminum heat dissipation fins and a rear-mounted ventilation port keep the power transistors from overheating.

The Tesla Roadster can be recharged in two different ways;
- Home Recharging; install a recharging station by an electrician in your
garage.
A completely dead battery can be full recharged of 220-volt, 70-amp outlet
within 3.5 hours. The way of recharging is quite familiar to our cell phone
recharging system, by plugging it in overnight and getting a fully-charged
power so the car is ready for driving in the morning.
- A Mobile Kit; No matter where you are, this allows the car to be recharged in
anywhere of electrical outlet as soon as it almost runs out of battery. The
different outlet- configuration of voltage levels using (110-volt or 220-
volt) differ the length of time recharging consumed.

Many people heavily concern about the reaction explosion which is the possible accident that they are afraid. In this case, the Tesla Roadster is designed and provided the highly safety energy system for it. First, the battery system was extensively "catastrophe tested," which involved heating individual cells until they burst into flames. The isolating of cell sets to prevent the adjacent flammable cause there will not allow any chain explosion.
Another important safety system in the Tesla Roadster’s PEM is the acceleration-detect control sensors that control the deceleration or detection even tilt, temperature and smoke as well. Whenever any abnormal are sensed, such as a car crash, the electrical power will be disconnect and shut down.

Tesla Roadster Motor and Other Features
The Tesla Roadster performance is not only its top speed of 130 mph or reaching of 60 mph within four seconds but also the unique properties of torque and power band.

Toque provides the turn and rotation of things in which the major horse power be generated by large amount of toque even at the very low RPM, the motor is able to reach quite high about 13,000 RPM and power band controls the speeds operation under the efficiently working engine.

The tree-phase, four-pole electric induction motor is the heart of the Tesla Roadster with the weight of 70 pounds. It can provide the high response of power for the driving. The Tesla Roadster has just three gears, with manual shifting and without clutch in order to eliminate the need for s complicated transmission.

As a status of new technology-electric car, the Tesla Roadster has been designed in a sports car’s feeling and looking. There are a few unique features which are the additional of the basics (heated seats, a stereo with CD player, ABS brakes and dual airbags) ;
• A unique PIN to start the car and prevent hot-wiring
• A Homelink transceiver you can program to control radio-frequency controlled devices such as your community gate and garage door
• A dock connector for your iPod
• Electrically-controlled door handles (there's no mechanical lock, which makes it more difficult to break into the car)
Since it's a convertible, the Roadster comes standard with a soft top. Options include a hard top as well as features like a full leather interior and a satellite navigation system.

Tesla Motors and the Future of Electric Cars
Martin Eberhard and his business partner Marc Tarpenning are the founder of the Tesla Company whom without any experience in the auto industry. The Tesla Roadster and the Tesla company have an unusual history. The company has almost no connection to the traditional American auto industry. They had an object to found a company to create the world’s first high-performance electric car which has to get mass appeal by the inspiration from a portable eBook. Eberhard often refers to the previous electric car s as “punishment cars” so this makes he decide to create the better ones himself.

Nikola Tesla
Eberhard named his new company after scientist, inventor and engineer Nikola Tesla. Tesla developed three-phase electric motors like the one used in the Tesla Roadster.
After netting $60 million in investment funds, (including over $30 million from Elon Musk, co-founder of PayPal), the new company chose a design from England-based Lotus. Eberhard took advantage of outsourcing, which made the various elements easy to acquire.

Tesla is a car-to-order manufacturer as the small runs production of their partner” Lotus' Hethel, England”. The Tesla Roadster is based on the Lotus Elise -- they look superficially similar and have the same basic chassis (though the Roadster's chassis is heavily modified) and other parts. This added to the convenience and savings. While most of the Roadster's parts and systems, such as the stereo, the brakes and the battery chargers are off-the-shelf, final assembly happens at Lotus facilities.

Are Electric Cars Finally the Next Big Thing?
It is the fact that cost of the first innovation-technology electric car always very high but for the time after, the price comes down then the cars are able to move down to the market. In this present time, still the Tesla sports cars are suited for only the high-end customers which are made in limited orders.
The company has been succeeded within the limited order of Roadster as the 100 limited edition "Signature Series" Roadsters sold out and the next 100 is ready to run the production for the new customers’ pre orders. A fully-loaded Roadster will cost $100,000, with a $75,000 down payment required to reserve one.
In 2008, Tesla plans to release “White Star”, a four-door electric sedan to the market.
Even though the purchase of an electric car seems to be much more expensive than a combustion-engine car but the environmental impact and saving in the long run of fuel cost are the very important substitution.
-An electric car has zero emissions and doesn't add to pollution.
-Driving an electric car a mile costs a fraction of what it costs to drive a gas-powered car a mile.
Tesla and other electric car proponents respond that electric cars are more efficient for several reasons.
First, generating power at a power plant, even a coal power plant, is more efficient and creates less pollution than millions of small combustion engines creating the power.
Plus, some of our electricity comes from cleaner power plants like hydroelectric plants, wind farms and solar cells.
In an interview with Wired.com, Eberhard claimed that the energy in a gallon of gasoline could drive an electric car 110 miles. Comparing average gas prices and electricity prices, the Roadster could go 150 miles for the price of one gallon of gas. Tesla reports twice the efficiency of even the greenest hybrid cars.
