    Some basic EV facts Part I

    Despite my posting a link to the Electric Auto Association's website, though I'd post info direct to educate a few of you non-believers.

    It's from

    Electric Vehicles FAQ's

    What is an electric vehicle?
    An electric vehicle (EV) is one that draws its power from electricity stored in batteries, instead of from the combustion of liquid fuels. EVs include handicapped carts, golf carts, industrial machines, and full-sized passenger cars.

    What are the advantages of an electric vehicle?
    EVs have many advantages which make them ideal commute vehicles or second cars.

    Convenience. EVs do not need tune-ups, oil changes, mufflers, fuel pumps, carburetors, etc. No pollution. EVs create no exhaust fumes, no gas, no coolant, and no waste oil. Even including the pollution from the utility's power plant, an electric car is 97% cleaner than a gas car. That's good for the environment, and it also means less hassle for the owner: no smog inspection needed, no complex and expensive emission control system to break down.

    Efficiency An electric motor provides useful energy more efficiently than a combustion engine. In addition, no energy is wasted when the car is sitting in stopped traffic. (In Los Angeles alone, 72 million gallons of gas are wasted annually by waiting in traffic)

    Quiet. EVs are almost completely silent.
    Durability. Even the best-kept gas car will eventually need a new engine. An electric motor has a virtually infinite life span, needing only an occasional change of brushes, which costs approximately $100.

    Also, starting July 1, 2000 electrics will be granted special access to HOV (car pool) lanes regardless of the number of passengers.

    What does an EV cost?
    Today's EVs are either kit cars, gas cars that have been converted to electric power or purpose built cars such as GM's EV-1, Ford's Ranger EV or Solectria's Sunrise or Force (Honda's EV-Plus, Toyota's RAV-4EV & Daimler-Chrysler EPIC are currently not available).

    All numbers given here are averages. The cost of conversion is about $7500 for components and batteries, and takes 200 hours. Depending on the features. Assuming you have a chassis, conversions that included parts and labor run approximately $15,000. Completed kit-cars run about $20,000 and purpose built cars are generally $25,000 to $60,000 or lease at $400 to $700 per month. Leased cars usually include full maintenance and in some cases will include the cost of insurance and a charger.

    What are the operating costs?

    An EV costs about 3 to 5 cents/mile for electricity, in any traffic. For comparison, at the cheap gas price of $1.50/gal., gas costs 7 to 8 cents/mile for fuel, depending on traffic. A gas car also requires maintenance services, averaging $400 to $600 per year, which an electric car does not need. Total expenses over 100,000 miles are about 8 cents/mile for an EV and 22 cents/mile for a gas car in the same use.

    • Pros & Cons.... give good pros...but what about cons...motor brushes cost $100.?What about labor, how long to change brushes? What about battery weight....what about an accident? What about all the toxic chemicals IN the batteries that can pollute the air? What an accident, the batteries get ruptured, and spew the chemicals (likely battery acid), all over the place? Cost of replacing batteries..(somewhere around $10K! How much to re-charge every 200 miles?
      What about cold weather....which batteries hate? Frozen car in an outdoor parking lot on a cold workday morning? How much heat do you get from a battery as compared to a gas engine? Ahhh ok... you live in Southern states...what about A/C? How much power is drawn from the A/C to keep you cool or run the radio, radio is hardly an issue, but draws power....GPS or other juice drawing toys inside the car? Drive at night?? How much power is drawn for running lights, thus cutting your travel distance before re-charge.. That also will affect the proposed 200 mile range.
      Clean, green & mean? Where does the electricity for re-charge come from? Ahhh good old coal...for the most part, since no one wants nuclear power lately....or at least until we can "properly & safely" dispose of nuke wastes.
      Coal is dirty....but still cheaper. save on gas, but you/we all would be putting more of a demand for electric power, thereby burning more coal.
      We don't get something for nothing. Energy is used to make the metal to make cars, and it takes energy to make the cars move!!
      Until we learn to live more conservatively & simply...we will have big problems! We don't NEED everything....big boats, 2nd homes (all air conditioned of course), luxury cruises, villas in Spain, expensive flights to wherever, pools, hot tubs....etc.
      We must learn to live simply.....or pay the price .

      • At least you choose to listen. These electric motors last for years (or many miles). Costs are cheaper considering, unlike a gas vehicle, you haven't had ANY oil changes, need for oil or fuel filters, etc. Ask the guys at Many drive their homebrew EVs for years before brushes are necessary. And yes, both heat or cold are concerns. Many Prius owners have proven that their cars in Michigan and other cold places have survived. Heat generally has not been as great an issue other than the need for AC. Calculations of auxiliary power using an extra auxiliary battery has not proven to be a great concern unless you're a young kid with booming stereo. Even then, traction batteries to drive the car has a greater need. Driving distance is NOT impacted due to separate batteries. If you want real answers ask my EAA buddies as they have driven cars for years with more experience. Too bad you aren't in Slicon Valley as you could ask them at the upcoming EV Rally, usually in October. I have my Prius, so that is my only experience. My twin electric motors plus gas engine smoke past many gas vehicles huffing and puffing for air going over Altamont Pass. For a real challenge, try driving Pike's Peak in Colorado. Electrics with pure battery power will smoke any gas vehicle. Lastly, coal power to recharge? Here in California we have a mix of hydroelectric power from dams. And while there is still coal, calculations prove time and time again that electric vehicles use less coal compared to pollution by gas vehicles. Wish you guys could hear the more facts from EAA members. I only posted but a few things from their website.

      • You both make very good points! Here's my take:I'm here to make money first.My 74 year old dad is pretty cool dude and all the time says hey solar is going to be great.Then I say oh yeah when you going to buy it?Well I do know the answer to that.Never!To make this tech tick you need a reason and that only reason is a whopping 2000.00 electric bill and it's got to monthly.With the EV it's going to take 10.00 gal for gas....and hope like hell the electric bill doesn't skyrocket at the same time.The stock???? Oh yeah hehehe people will buy that just to make themselves feel good.
