Tesla Roadster Breaks Distance Record For Electric Car

An anonymous reader writes "The CEO of an Australian ISP has driven his Tesla Roadster into the record books, completing 501km on a single electric charge in the 2009 Global Green Challenge — beating the Roadster's official specifications, which rate the all-electric sports car as being capable of a maximum of 390km per charge. The previous record was held by another Roadster in the 387km Rallye Monte Carlo d'Energies Alternatives in April this year. In a race specifically designed for alternative energy vehicles (such as hydrogen and electricity), the Roadster was the only vehicle to complete the entire course. Though to be fair, that race course was a mixture of twists, turns and hills."

      I think what they mean was that it requires less electricity to remain straight on a flat plane going at a fixed speed. When you slow down to complete an S-curve or start going up a hill, your fuel consumption is drastically affected. The driver of the Tesla Roadster kept the speed as close to 55 kmph as he could to achieve the best efficiency event though that's a modest pace and not really a racing speed. This wasn't a course making long straight lines through the salt flats and that's probably important to note. I don't think "race" is a good description for the course. It's more like a realistic challenge with completion time hardly a factor.

Iron, phosphorus, and manganese are ridiculously easy raw materials to come by, as I'm sure you know (cobalt, not so much). The anodes are generally various forms of carbon (graphite, amorphous, etc). Tesla had to go with the cobalt-type cells (which are the same type as found in laptops) because that's all that was affordable and available in bulk when they started.

The brine is pumped up to the surface into evaporation ponds, then precipitated to isolate the individual salts; the remaining brine is returned to the subsurface, minus whatever salts are of commercial viability. It's a very low impact production process -- much less than, say, iron mining and smelting for parts for internal combustion engines ;).

Thus, the Elise will have a better power-to-weight ratio (the 0-60 speed is based on the low-end torque of the electric motor being full-power from off the line until the maximum). When on the same suspension (which is one of the shared component sets) this weight increase can also drastically reduce the viability of a vehicle as a sports car since it now has a much harder time moving around corners.

      A normal car has tens of liters of gasoline in it, each with the energy of about a dozen hand grenades. What if something goes wrong?

      To elaborate the point, TNT has 6.92 MJ/liter, or 4.6 MJ/kg energy density. Lithium-ion batteries have 0.46-0.72 MJ/kg, or 0.83-0.9 MJ/liter. Gasoline has 46.4 MJ/kg, or 34.2 MJ/liter; this doesn't include the amount of oxidizer needed, though. A quick estimate would suggest that adding oxygen to the calculation (as a stoichiometric mixture of gasoline and oxygen) would about quarter that. Water has a specific heat capacity of 4186 J/(kg*K), which means a thermos containing almost boiling water contains (relative to 20 degrees Celsius) 0.33 MJ/kg, a bit lower than a lithium battery by mass.

      A more simple point is this: to move a certain car body (with occupants and luggage) a certain distance, you need a certain amount of energy, no matter how you store it. Therefore, two identically-sized cars that have the same range need to carry the same amount energy on them, irrespective of how that energy is stored. However, electrical cars are lighter, more efficient (storage-to-kinetic) and have lower range, therefore the energy-per-car density is much lower than a gasoline car.

      Third point: grenades are useful (for their purpose) because they release their energy _really_ quickly. They are expensive because it's quite hard to make things release their energy _really_ quickly.

    According to Tesla motors official specifications the motor has a output of 248 peak horsepower (185kW) and 276 ft/lbs (375 Nm) of torque. Also, for full charge it takes "3.5 hours using the Tesla Motors Home Connector at 240 Volts and 70 amps" which for simplicity and because they have neglected to disclose the actual kwh of full empty to full charge at room temperature (capacity will degrade with use) lets assume is 3.5hrs * (240V * 70A) = 58.8 kwh. Most likely this is an overly conservative estimate because of the constant current constant voltage nature of charging lithium batteries. This is more important than battery capacity because it is the load the power plant feels to charge your car and is the important quantity of interest. This will take you 244 miles on average (from same site) of course flat straight stretches will get better but it is the average that is most important. Total is 58.8 kwh/ 244 miles or about .241 kwh/mile. You can do the math on charging, but it should be obvious at this point that it is much cheaper than gasoline since electricity costs from around 7-20 cents/kwh in the US depending on numerous factors.

    Now go look at EPA official website for determining CO2 emissions (in the US) and you can see that generating one kwh gives you 7.18x10^-4 metric tons of CO2. In addition, they also state on the same page you generate 8.81*10-3 metric tons of CO2 per gallon gasoline.

    Lets do some simple math. At .241 kwh/mi this gives you (.241 kwh/mi * 7.18x10^-4 metric tons CO2/kwh) = 1.73 x 10^-4 tons of CO2/mile. At 8.81 x 10^-3 metric tons of CO2/gallon (from EPA) then you have the Tesla getting 50.91 MPG equivelant CO2 pollution. Note that hybrid vehicles and diesels both come close to or exceed this value making the CO2 pollution for a pure electric not as rosy as some have been led to believe.

After all, right now we power most of the electric grid with coal and until that changes it dosen't make sense to wish or just assert what things out to be instead of just doing some simple research and high school physics calculations.

    Let's look at the real data from the real sources...

    According to Tesla motors official specifications [teslamotors.com] the motor has a output of 248 peak horsepower (185kW) and 276 ft/lbs (375 Nm) of torque. Also, for full charge it takes "3.5 hours using the Tesla Motors Home Connector at 240 Volts and 70 amps" which for simplicity and because they have neglected to disclose the actual kwh of full empty to full charge at room temperature (capacity will degrade with use) lets assume is 3.5hrs * (240V * 70A) = 58.8 kwh. Most likely this is an overly conservative estimate because of the constant current constant voltage nature of charging lithium batteries. This is more important than battery capacity because it is the load the power plant feels to charge your car and is the important quantity of interest. This will take you 244 miles on average (from same site) of course flat straight stretches will get better but it is the average that is most important. Total is 58.8 kwh/ 244 miles or about .241 kwh/mile. You can do the math on charging, but it should be obvious at this point that it is much cheaper than gasoline since electricity costs from around 7-20 cents/kwh in the US depending on numerous factors.

    Now go look at EPA official website for determining CO2 emissions [epa.gov] (in the US) and you can see that generating one kwh gives you 7.18x10^-4 metric tons of CO2. In addition, they also state on the same page you generate 8.81*10-3 metric tons of CO2 per gallon gasoline.

    Lets do some simple math. At .241 kwh/mi this gives you (.241 kwh/mi * 7.18x10^-4 metric tons CO2/kwh) = 1.73 x 10^-4 tons of CO2/mile. At 8.81 x 10^-3 metric tons of CO2/gallon (from EPA) then you have the Tesla getting 50.91 MPG equivelant CO2 pollution. Note that hybrid vehicles and diesels both come close to or exceed this value making the CO2 pollution for a pure electric not as rosy as some have been led to believe.

    Note that this is bested by emissions from diesel vehicles at this point. Untill fission or fusion or solar or whatever comes on line, and given the cost of these vehicles, it dosent make sense. Even if the battery were somehow cheap *now* it still wouldn't make much enviornental sense over a efficent chemical fuel based design. the best bang for the buck, since CO2 polluters aren't all rich, is to utilize efficent fossil fuel vehicles
