[1] [2] It offers AC-induction traction motors. [3] The company produces electric vehicle drive systems featuring high performance, high efficiency induction motors and integrated high power battery charging. [3] [4] Previously, they built an electric sports car, the tzero [2] and the eBox, [2] an electric conversion based on the Scion XB. They ...
Lateral view of the AC Propulsion eBox. AC Propulsion executives announced their intention to convert Scion xBs to battery electric vehicles in October, 2003.

Where higher speed is desired, these motors can be operated in parallel, making a higher voltage available at each motor and so allowing ...
The formula for the cost of charging an electric car is: Cost to Charge = (CR / RPK) x CPK ... this percentage to create an apples-to-apples comparison. Using this math, the average car with a 360 ...
The tZero (a mathematical symbol meaning, 'time from a standing start in sequence') is a hand-built electric sports car designed and built in very limited numbers by the U.S. pioneering company AC Propulsion in the mid 1990's.
