How do these new electric vehicles work?
What materials are used to produce power for these vehicles?
You charge the batteries from household AC power via a battery charger. Batteries get charged up and this is your power source to operate the motor.
Motors can be either DC or AC. AC motors require inverters to convert DC into AC and can use variable frequency drives to operate the AC motor at different speeds. AC is a much more expensive system but has advantages like ease of implimenting regenerative braking. DC motors can use PWM speed controls to control motor speed. DC regenerative braking usually requires switching gear.
Accessories that we are accustomed to in regular internal combustion engine cars can be difficult to provide. Power Steering, Power brakes and air conditioning are some examples. Power brakes would require an small electric motor vacuum pump and receiver as a vacuum source. Power steering and AC could also be driven off of accessory motor but can also be powered via a power take off from the main motor. Down side to this method is loss of these accessories when the motor is running at low speed or stopped.
I am conducting a little poll to see how many people would use an electric car if it were efficient to charge (multiple charging stations, long range, and low cost).
In other words, would you drive a car that you could pay $0.75 (per 40 miles) to fill up vs. $4.00 (per 40 miles).
Just say YES if you would. Or if you wouldn’t please state why.
Electric cars are a non-starter in the USA. People are too wigged out about the battery-range thing. Wait until plug-in hybrids are common, and people go a whole year without ever using the onboard gas engine, and they start going "hey wait, why did I pay $5000 extra for the gas engine?" And people will figure out that electrics CAN work.

Electric conversion refers to converting old models of cars into electric or hybrid vehicles by gutting the internal combustion engine and replacing them with electric drive components. Learn about the progress of electric conversion with information from a green car specialist in this free video on eco-friendly vehicles.
