NEW ELECTRIC SPORT CAR <img src="/styles/default/xenforo/smilies/default/yes.gif"  class="smilie" loading="lazy" alt=":yes:" title="Yes    :yes:" data-shortname=":yes:" /> <img src="/styles/default/xenforo/smilies/default/yes.gif"  class="smilie" loading="lazy" alt=":yes:" title="Yes    :yes:" data-shortname=":yes:" /> <img src="/styles/default/xenforo/smilies/default/yes.gif"  class="smilie" loading="lazy" alt=":yes:" title="Yes    :yes:" data-shortname=":yes:" />  <img src="http://www.fastcursor.com/vehicles/images/tesla-roadster-pic-1.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://peswiki.com/images/1/14/Tesla_Roadster_front_back_300.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> Unlike a traditional gasoline-powered car, the Tesla Roadster doesn't contain hundreds of moving parts. It's powered by just four main systems:     * The Energy Storage System (ESS)     * The Power Electronics Module (PEM)     * An electric motor     * A sequential manual transmission <img src="http://static.howstuffworks.com/gif/tesla-roadster-1.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> In place of an internal combustion engine, the Tesla Roadster sports a bank of batteries -- the Energy Storage System (ESS). In developing a power source befitting such a high-performance car, Tesla went with technology proven in the laptop computer field -- rechargeable lithium-ion batteries. The Roadster contains 6,831 of them. They weigh about 1,000 pounds in total, and Tesla claims that they provide "four to five times the energy-density stores of other batteries" . The batteries fit into 11 sectors with 621 batteries each. A separate computer processor controls each sector to make sure all of the charging and discharging is handled smoothly. <img src="http://static.howstuffworks.com/gif/tesla-roadster-11.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> The Energy Storage System is located in the rear of the vehicle. <img src="http://www.fastcursor.com/vehicles/images/tesla-roadster-pic-2.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> The Power Electronics Module (PEM) is a power inverter and charging system that converts DC power to AC power using 72 insulated gate bipolar transistors (IGBTs). This results in a marked increase in power output compared to first-generation electric cars. Under peak acceleration, the batteries can crank out 200 kW of energy -- enough to light 2,000 incandescent light bulbs. In addition to controlling charge and discharge rates, the Power Electronics Module controls voltage levels, 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. You can recharge the Roadster in two different ways. An electrician can install a recharging station in your garage. This 220-volt, 70-amp outlet allows for a full recharge in 3.5 hours from a completely dead battery. Tesla likens charging your car to charging your cell phone; you can plug it in at night and have a fully-charged car in the morning. There's also a mobile kit that allows recharging at any electrical outlet, no matter where you are. The length of time it takes to charge using the mobile kit depends on the outlet configuration that you're using (110-volt or 220-volt). <img src="http://static.howstuffworks.com/gif/tesla-roadster-2.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> Tesla Roadster Motor and Other Features The heart of the Tesla Roadster is its 3-phase, 4-pole electric induction motor, which weighs just 70 pounds. Tesla's claims and independent testing show that the Roadster can reach 60 mph in about four seconds and its speed will top out somewhere around 130 mph. But the Roadster's performance isn't just about speed and acceleration. The unique properties of an electric motor give it a huge advantage over a combustion engine in terms of torque, force that tends to rotate or turn things, and power band, the range of operating speeds under which the engine operates efficiently. The Roadster can generate large amounts of torque even at very low RPM, and the motor can always turn out major horsepower. It can reach over 13,000 RPM, something very few large combustion engines can do. The Tesla Web site includes the following: "A favorite trick here at Tesla Motors is to invite a passenger along and ask him to turn on the radio. At the precise moment we ask, we accelerate. Our passenger simply can't sit forward enough to reach the dials" <img src="http://static.howstuffworks.com/gif/tesla-roadster-4.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://nudo.nu/wp-content/tesla_roadster.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> IF YOUR REALLY INTERESTED FIND OUT MORE ABOUT THIS AMAZING CAR <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> <img src="/styles/default/xenforo/smilies/default/cool.gif"  class="smilie" loading="lazy" alt=":cool:" title="Cool    :cool:" data-shortname=":cool:" /> </blockquote>
