Thermal Systems

Overview and Information

The price of oil is up; gas guzzling are out and the race for a fuel free electric car is on. This includes the suspects of Japan, Detroit, and but what shocked most car was a new company with virtually no building cars has entered the Silicon Valley. The jury is out as to whether or not electric cars can really be practical, but the computer in California are betting that inventiveness can beat out Detroit’s bureaucracy in producing a viable car.

One of the reasons electric have never taken off has battery technology. A few years ago began to wonder, “why not use the that they put in laptop called lithium ion batteries?” when the environmentally conscious tech industry in California in.

Figure 1 Tesla Roadster

1 is the first all electric roadster by Tesla Motors, a small in northern California. The chairman of Elon Musk says the Roadster can accelerate from to sixty in approximately 4 seconds and is by 6,831 rechargeable lithium ion and not a single drop of oil. Musk helped launched 5 years ago with no experience at all in the car and now has over 1,000 orders for high tech, sporty

While the roadster may be fuel it isn’t so friendly on the old pocketbook. it comes to the initial investment have to make in order to one of these vehicles in your The Tesla Roadster some a hefty price tag of $109,000 chairman and CEO Elon Musk “a steal with twice the of a Toyota Prius.”

From the Musk wanted to prove the innovative and nimble Silicon could build a better car than what he called lumbering bureaucratic Detroit.” the price of oil is down most due to the current election, as we learned in prices are believed to reach an all high between the years of and 2047. This doesn’t take into account the effect, which even the importance of “not just an all car but a green friendly vehicle.” Tom of DuPont Registry furthers thoughts by stating that the luxury marketplaces’ tradition of environmental chance, the technological and social implications that go with environmentally friendly are creating a social consciousness and the exotic car market.”

This year, 2008, the a new electric roadster wins International Design Excellence sponsored by Business Weekly and the Industrial Designers Society of With this accomplishment, electric and future vehicles are not too far out of the Quoted from Tesla “The very definition of is freedom of motion. The word originated as a literal way to define a that moves under its own without need for another – such as a horse or locomotive. the definition of automobile often association with an internal engine.

We’re here to this definition one car at a time. The will once again use the to transport us free of convention. Motors will be part of liberation. The Tesla Roadster not only under its own power, but free of the existing and increasingly petroleum-based infrastructure, [((bibcite )))].”

Founded in 2003 by Eberhard, Marc Tarpenning, and Musk, Tesla motors as a small company that and developed new, original for car enthusiasts. Elon Musk, Product Architect, and CEO, has the main funding source for the since the beginning. He is better for co-founding PayPal, Zip2, and SpaceX.

Now in 2008, Tesla is taking flight and has well 250 current employees. Their to create the most energy-efficient car on the while blending a beautiful style with high Their first production the 2008 Tesla Roadster, accomplishes this task.

To put into perspective, listed are some general specification to the performance of this new ground-breaking vehicle.

Unlike the current of automobiles, the Tesla Roadster is up of only four main the Energy Storage System the Power Electronics Module an Electric Motor, and a Sequential Transmission.

Energy Storage (ESS)

The Tesla Roadster a collection of 6,831 lithium-ion which takes the place of an combustion engine. They are in the rear of the vehicle mounted in 11 A computer then controls sector to ensure proper of charging and discharging of the energy.

batteries are pretty much the battery that one would for a present day laptop computer. the total weight of this is approximately 1,000 pounds, makes up the majority of the car’s weight. These batteries are to be able to provide five the energy-density of other batteries.

Morgan Electric Cars

the roadster runs strictly on it must have a way to be recharged. Motors has come up with two ways to accomplish this One possible way is to have a certified install a “recharging station” in home. This station of a 220 volt, 70 amp outlet that can those 6,831 batteries in about 3.5 to 4 hours from dead. The second option a mobile connection kit from Motors that can be plugged any standard outlet.

The vehicle can be plugged into this kit to the charging process to occur. option will take more time to charge the depending on the outlet configuration. A 110 volt outlet will approximately double the time of the 220 source [((bibcite (http://auto.howstuffworks.com/tesla-roadster.html

Now some may be thinking, Well, charging this car cause a increase in a home electric The Tesla Roadster will a slight jump in an electric but it sure is not what one would Tesla Motors claims it will cost roughly per mile driven. Since the car can over 220 miles on a single that equates to $2.20 for one charge.

This sounds way to to be true. Well, it just not stop there. Tesla also states that on where you live, you can also be to the following:

Single-occupancy access to all lanes

Income tax credit new legislation)

A luxury car that’s exempt from the luxury car tax

parking at charging stations at LAX

No meter fees in an increasing of major metropolitan areas

The price tag starts to seem and more reasonable.

Power Module (PEM)

The PEM system, locateded in the rear of the vehicle, is a power inverter and charging Its job is to convert DC power to AC power by 72 insulated gate bipolar (IGBTs). First generation powered cars did not use this technology which caused a lower power output the new Tesla Roadster.

In addition, the PEM is responsible for controlling the voltage RPM’s of the motor, torque, and the braking system. The regenerative system helps provide to the batteries by using energy braking to slow the car down. kinetic energy is transferred to the EES system, helping to improve the efficiency of the EES, PEM and motor by 85 to 90

In turn, this allow the motor to produce a maximum of of output power [((bibcite )))].

The Electric Motor

The Roadster motor is a 3-phase, electric induction motor. The is equivalent to the size of a large and weight about 100 lbs. really separates the power of a Roadster to a sports car is very At 0 rpm, the roadster can generate its torque of 276 ft-lbs.

This motor is also of reaching a 14,000 rpm redline, most combustion engines do. When the Roadster is put on the drag against its competition (Viper, Lamborghini, Porsche, Mclaren F1, ), this unique feature of the motor gives the car the ability to these prominent sports look like a joke. The car off the line and all of its power which is to the wheels goes directly to The roadster does not have any problems from acceleration due to its power band, unlike sports cars and finishes the in first. Tesla Motors that they play a on all of their new customers when sit in the car for the first time for a test

A favorite trick here at Motors is to invite a passenger and ask him to turn on the radio. At the precise we ask, we accelerate. Our passenger can’t sit forward enough to the dials!

Sequential Transmission

the motor to this vehicle is so it requires a simple transmission. The has just three gears. are two forward gears and one reverse The shifting is manual but there is no required.

If there is no clutch, there is no stalling, jerking, or a large gap to switch gears http://auto.howstuffworks.com/tesla-roadster1.htm ))].

In the new and upcoming models, a new transmission is going to be since some slight have come about. Its to reduce the two forward gears to one and still include the one reverse Because of this change, it slightly limit the performance of the acceleration. To make up for this, Motors is going to beef up the and add an new coolant system to compensate for the

All 2008 model owners have a recall in which will install the new motor and free of charge.

Well-to-Wheel

To put into perspective just how this vehicle is, it must be to other modern fuel vehicles in a well-to-wheel efficiency Tesla Motors claims and by their word that roadster presents double the of the top hybrid cars on the market and emits one-third of the carbon When this roadster is to our exotic sports cars, it has to be six times as efficient and emits of the pollution.

The following data below a comparison of the Tesla Roadster the latest fuel efficient [((bibcite http://www.teslamotors.com/efficiency/well_to_wheel.php ))].

Our hybrid vehicles can get up to 55mpg. seems incredible, but the Tesla blows the competition out of the water. It is by Tesla Motors that roadster contains a equivalent of 2.1 gallons of petroleum.

After for 220 miles, this shows to be a 100+ mpg equivalent, and costs a $2.20 for a fill up!

In conclusion, the Roadster has shown to a an astonishing that provides reliability, and performance to its owner. Its an environmentally machine that gives the an adrenaline rush as if driving a with the top down at 100mph. Its engineering has separated this into its own category. No other efficient automobile on the market can compare.

Tesla’s business is build off of the views of their key who believe that new and innovative can be very pricey. As technology the Roadster can move down the making it available to a wider of people. It is for this reason Tesla marketed its first as a high end sports car, to a very high end clientele.

Is its worth every penny? You can be the of that.
