Try to get parts for an electric car from NAPA.
I thought you said electric cars dont need parts.

Care to quote me?
I said they don't require costly maintainence, only about $10 a year for brushes for the electric motor[s] (if you use a brush type motors). About every 6 years, they need to have the batteries replaced.
Nethier of which are available at NAPA.
I know this is going to sound foolish but what type of battery does and elec. car take? I always pictured it using something similar to a car battery they type sold at NAPA stores.
The problem with electric cars is the less they weigh, the further they go. Lead-acid batteries like in regular cars are not ideal for this because they contain lead. Most electric cars use lighter batteries than can deliver high-current, and can sustain sudden high current charges (regenerative braking).
The best battery for all these conditions right now is a Lithium Polymer type, or Lithium Ion as they are cheaper, but don't have the high current charge ability. This can be offset by a high charge/discharge capacitor. You can't get these types of batteries at NAPA.
Lead acid batteries also have a high 'fall off' discharge, where peak voltage and current are only available when the battery is fully charged, and diminished quickly as the battery loses that full charge. Li-Poly and Li-ion keep delivering full charge until they are nearly dead.
The biggest hinderance to the electric vehicle right now is the power storage density VS the available power from gasoline. When better batteries are available, electric cars will be exceeing ranges of IC cars.
