electricity was preferred in automobile propulsion. Advances in internal combustion technology especially the. electric starter the greater range of gasoline cars quicker. refueling times and growing petroleum infrastructure along. with the mass production of gasoline vehicles reduced prices of. gasoline cars to less than half that of equivalent electric cars. which led to the decline of electric propulsion, The energy crisis of 1970s and 1980s brought a renewed. interest in electric vehicles, Further the global economic recession of late 2000s called to. abandon the fuel inefficient SUVs in favor of small cars hybrid. cars and electric cars,Indo German Winter Academy 2011 3.

Gasoline Engine, The Electric Motor gets its power from a controller. The Controller is powered from an array of rechargeable. http auto howstuffworks,com electric car,Indo German Winter Academy 2011 8.

Electric cars can use AC as well as DC motors,DC motors run on a voltage ranging roughly. between 96 to 192 volts Most of them come,from Forklift Industry. DC installations are simpler,Another feature of DC motors is that they can. be overdriven for short periods of time up to a,factor of 10 which is good for short bursts of. acceleration,One limitation is the heat build up May lead to.

Due to these limitations and other advantages provided. by AC motors like better torque and speed output for. same weight and size DC motors are not used, Any of the industrial 3 phase AC motors can be used. They allow the use of regenerative braking,Forklift Motor AC Motor. Courtesy DIY Electric car blog Courtesy DIY Electric car blog.

AC Controller, An AC controller creates 3 pseudo sine waves which. are 120 degree apart 3 phase AC,A three phase inverter. Using six sets of power transistors the controller. takes in 300 volts DC and produces 240 volts AC,Indo German Winter Academy 2011 15.
